BACKGROUND

Usually, in a vehicle transmission, the selection of transmission ratio steps or control of switching programs takes place by means of an actuating device arranged in the reaching re o the hands of the driver. For this purpose, actuating elements, such as gearshift levers or selector levers, are used, which are arranged between the front seats, in the area of the steering wheel or in different areas of the vehicle interior. Usually, shift actuations are developed in accordance with a specific vehicle model to fulfill the different requirements regarding accessibility and ergonomics, as well as the resulting angles of activation.

The actuating device is characterized by an exchangeable module adapter, which is arranged between the lever housing and the transmission device. The module adapter is used to adapt the ergonomics point of the actuating device in the vertical and/or horizontal direction and thus to different installation situations.

BRIEF SUMMARY

Against this background, the present disclosure provides an improved transmission device for transmitting an angle of activation of a selector lever for a shift actuation of a vehicle transmission, a method for producing a respective transmission device for transmitting an angle of activation of a selector lever for a shift actuation of a vehicle transmission, as well as a method for transmitting an angle of activation of a selector lever for a shift actuation of a vehicle transmission. Advantageous embodiments are included in following description.

By means of a thrust-loaded transmission, an angular position of an actuating element or selector lever can be transmitted to a sensor device, wherein a configurable force application point of the pivot bearing of the thrust-loaded transmission can cause on one of the levers a change in transmission. At the same time, the actuating element can cause a rotation of a transmission lever, wherein the rotation or deflection of the transmission lever is transmitted to a second lever, which is equipped with a sensor or which responds to a sensor. In the process, it is important that a transmission or a proportional value can be adjusted when the rotation or deflection of the transmission lever is transmitted to the second lever.

A transmission device for transmitting an angle of activation of a selector lever for a shift actuation of a vehicle transmission comprises: a transmission lever, which is pivoted about a first axis to receive the angle of activation of the selector lever; a signal lever, which is pivoted about a second axis to provide a transducer angle for a transmitter element of a sensor; and a drive device, which couples the transmission lever with the signal lever to transmit the angle of activation to the transducer angle of the signal lever, wherein a force application point between the transmission lever and the signal lever can be configured to adjust a proportional value between the angle of activation and the transducer angle.

A vehicle, especially a motor vehicle, can comprise a transmission or vehicle transmission. The vehicle transmission can have a plurality of transmission steps or shifting programs. A selection of a transmission step of the plurality of transmission steps or a selection of a shifting program of the plurality of shifting programs can be performed by means of a selector lever. For this purpose, the selector lever can assume a plurality of angles of activation. An angle of activation can be assigned a transmission step or a shifting program of the vehicle transmission. Usually, a selector lever involves an actuating device or a gearshift lever. The transmission lever can have an interface to receive the angle of activation of the selector lever. The first axis and the second axis can be spaced apart. The first axis and the second axis can be aligned in parallel at a tolerance range. The angle of activation and the transducer angle can be arranged proportional to each other. For example, the transducer angle can be set to respond to the angle of activation and a proportional value. The force application point of the drive device can be firmly connected with the transmission lever and simultaneously or additionally with the signal lever.

The drive device can comprise a coupling element and a guide unit for the coupling element. In particular, the drive device can comprise a linear guide unit. At the same time, the coupling element can be arranged in a receptacle at the transmission lever, and the guide unit can be arranged at the signal lever. In an alternative embodiment, the coupling element can be arranged in a receptacle at the signal lever, and the guide unit can be arranged at the transmission lever. The guide unit can be connected in form-fitting manner and additionally or alternatively in force-fitting manner with the transmission lever or the signal lever. The coupling element can engage in the guide unit. The guide unit can be designed in the form of a groove, a profile or a track.

The coupling element can be designed in the form of a pin or a bolt or can comprise a pin or a bolt. The coupling element can also be designed in the form of a pin or bolt with a sliding component. For example, the coupling element can be designed in the form of a push-in pin, a screw or a connector pin. The coupling element can move in the guide unit along a predetermined guide track. At the same time, the guide track can have a linear design. When the coupling element is designed in the form of a pin or bolt, one side of the coupling element can be arranged in the receptacle in the transmission lever or signal lever, and the other side can be guided in the guide unit. As a result, the angles of both levers can change in relation to each other. The angle of activation and the transducer angle can be different from one another. Alternatively, a pin or bolt can also be combined with a sliding component. As a result, the sliding component can glide in the guide unit. The sliding component can have a pivot bearing, in which part of the pin or bolt is arranged. Furthermore, the sliding component can comprise at least one slide bearing.

It is also advantageous when the transmission lever has at least one further receptacle. The at least one further receptacle and the at least one receptacle can be arranged radially to the rotation axis of the transmission lever. The receptacle and the further receptacle can each be spaced differently from the first axis. At the same time, the coupling element can be arranged in the at least one receptacle and in addition or alternatively in the at least one further receptacle. In an alternative embodiment, the signal lever can have one receptacle and at least one further receptacle, wherein the coupling element can be arranged in the receptacle or alternatively in the at least one further receptacle. By means of two receptacles placed at different locations, i.e., spaced at different locations in relation to the assigned axis, the proportional value between the angle of activation and the transducer angle can be configured or adjusted.

Furthermore, it is possible to arrange at least one magnet at the signal lever to be used as a transmitter element. In an alternative embodiment, a transmitter element in the form of a sensor can be arranged at the signal lever. When a magnet is used as transmitter element and arranged at the signal lever, a position or an angle, especially the transducer angle of the signal lever, can be detected easily and cost-effectively by a sensor, a plurality of sensors or a sensor field.

Next to the signal lever, it is possible to arrange a circuit board. The circuit board can comprise at least one sensor. The at least one sensor can be integrated in the circuit board or arranged on the circuit board. The circuit board can have a sensor field or a plurality of sensors. The transmitter element can be moved along a circular path over the circuit board in a plane that is in a tolerance range parallel to the circuit board. The at least one sensor or the sensor field can be designed to set a position of the transmitter element or a transducer angle of the signal lever. A signal of the at least one sensor or the sensor field can represent a position of the transmitter element, a transducer angle, a transmission step or a shifting program of the vehicle transmission.

Furthermore, the transmission device can comprise a locking device, which is designed to block in a locked condition a movement of the transmission lever and in addition or alternatively the signal lever. For this purpose, the locking device is able in locked condition to engage in a locking recess of the transmission lever. For example, the transmission lever and in addition or alternatively the signal lever can have a recess or a drill hole into which a locking device can engage. The locking device can be moved mechanically or electrically and can be moved into a position which blocks the transmission lever or signal lever in a rotational movement or angular change.

It is also advantageous when in one embodiment the transmission device has a housing. As a result, it is possible to support with the use of the housing the first axis and additionally or alternatively the second axis. The first axis and additionally or alternatively the second axis can be supported at the housing. A housing can protect the transmission device. A housing can also provide an easy assembly of a pre-assembled transmission device.

A method for producing a transmission device for transmitting an angle of activation of a selector lever for a shift actuation of a vehicle transmission comprises the following steps: providing a transmission lever, a signal lever and a drive device; configuring a force application point of the drive device between the transmission lever and the signal lever to adjust a proportional value between the angle of activation and a transducer angle of the signal lever; and arranging the transmission lever, the drive device and the signal lever, wherein the transmission lever for assuming the angle of activation of the selector lever is pivoted about a first axis, wherein the signal lever for providing the transducer angle for a transmitter element of a sensor is pivoted about a second axis, and wherein the drive device couples the transmission device with the signal lever to transmit the angle of activation to the transducer angle of the signal lever.

The present embodiments can also be cost-effectively and effectively implemented by means of a method for producing a transmission device for transmitting an angle of activation of a selector lever to a transducer angle for a shift actuation of a vehicle transmission. In the step of configuration, an element of the drive device, such as a bolt or a pin, can be arranged in a receptacle of the transmission lever to adjust the proportional value between the angle of activation and the transducer angle of the signal lever.

A method for transmitting an angle of activation of a selector lever for a shift actuation of a vehicle transmission comprises the following steps: rotating the transmission lever about a first axis in response to an actuation of the selector lever to adjust an angle of activation; transmitting the movement of the transmission lever to a signal lever, wherein the angle of activation is transmitted to a transducer angle of the signal lever, wherein a proportional value between the angle of activation and the transducer angle can be adjusted by means of a configurable force application point between the transmission lever and the signal lever; and providing the transducer angle for a transmitter element of a sensor by means of the signal lever, which is pivoted about a second axis.

One aspect of the present disclosure is to provide a variable circuit with an integrated transmission system. Advantageously, it is possible to avoid a multiple development to accommodate different requirements regarding attainability and ergonomics, as well as the resulting angles of activation and actuating travel. For example, one model of the idea presented provides a shift actuation, which allows for different variations regarding angle of activation and actuating travel by using a uniform electronics and mechanical module.

DETAILED DESCRIPTION

In the following description of preferred embodiments of the present disclosure, the same or similar reference numerals are used for components having a similar working mechanism that are shown in the different figures, wherein the description of the respective components is not repeated.

FIG. 1 shows a diagram of a vehicle 100 with a vehicle transmission 102 and a transmission device 104 for a shift actuation of the vehicle transmission according to an embodiment of the present disclosure. The vehicle 100 comprises a motor 106, which drives at least one axis of the vehicle 100 via a vehicle transmission 102. The transmission device 104 comprises a transmission lever 108, a drive device 110, as well as a signal lever 112. The vehicle transmission 102 comprises a plurality of transmission steps or a plurality of shifting programs, which can be adjusted by an actuating element 114 connected with the transmission device 104, which is designed in the embodiment shown in the form of a selector lever 114. The transmission lever 108 is designed to be rotated about a first axis in response to actuating the selector lever 114. When a rotation of the transmission lever 108 is completed, the transmission lever has assumed an angle of activation, which corresponds in this embodiment to the position of the selector lever 114, i.e., to an angle of activation of the selector lever 114. The drive device 110 is designed to transmit the movement of the transmission lever 108 to the signal lever 112, wherein the angle of activation is transmitted to a transducer angle of the signal lever 112. For this purpose, the signal lever 112 is pivoted about a second axis. A proportional value between the angle of activation and the transducer angle can be adjusted by means of a configurable force application point between the transmission lever 108 and the signal lever 112. According to this embodiment, the transducer angle has a value that is different from the angle of activation and represents the position of the selector lever 114. By means of the signal lever 112, it is possible to adjust the transducer angle for a transmitter element of a sensor. In this way, it is possible to detect by the sensor and via the transmission lever 108 and the signal lever 112 a current angle of activation of the selector lever 114.

FIG. 2 shows a diagram of a transmission device 104 of an angle of activation α to a transducer angle β for a shift actuation of a vehicle transmission according to an embodiment of the present disclosure. The vehicle transmission can involve an embodiment of a vehicle transmission shown in FIG. 1 and depicted with the reference numeral 102. The transmission device 104 can involve a model of an embodiment of the transmission device 104 shown in FIG. 1. The transmission device comprises a transmission lever 108 and a signal lever 112, which are coupled via a drive device 110. In one embodiment, the drive device 110 is designed in the form of a thrust-loaded transmission. With one of the two levers 108, 112, i.e., with the transmission lever 108 or the signal lever 112, the drive device 110 is firmly connected to a force application point 220. With the other lever 112, 108, i.e., the signal lever 112 or the transmission lever 108, the drive device 110 is connected via a shear connector, which can be moved in linear direction along the lever 112, 108. The force application point 220 can be moved in linear direction in the shear connection. The drive device 110 couples the transmission lever 108 with the signal lever 112.

The transmission lever 108 is pivoted about a first axis 222. The signal lever is pivoted about a second axis. FIG. 2 does not show an interface for receiving an angle of activation α. The drive device 110 is designed to transmit the angle of activation α adjusted by the transmission lever 108 to a transducer angle β of the signal lever. In one embodiment, the position of the force application point 220 can be easily configured in relation to the transmission lever, and in a further embodiment, in relation to the signal lever. By changing the force application point 220 at the transmission lever 108, it is possible to adjust or configure a proportional value between the angle of activation α and the transducer angle β.

One aspect of the present disclosure involves the possibility of allowing for different variations regarding angle of activation and actuating travel by using a uniform electronics and mechanical module. In one embodiment, this objective is achieved with a transmission lever 112, which has a fixed point of rotation 222 and the force application point can be defined in variable manner. The resulting different lever ratios make it possible to represent different actuating travels at the operating area of the outer lever, which is transmitted to a movement of the signal transducer 112. The position of the actuating lever (shown in FIG. 1 with the reference numeral 114) is determined by means of a grid system.

This allows for a variant-independent same-part concept for the sensor unit. In addition, independent of the actual lever, a signal transducer (for example, a magnet) can be positioned in such a way that it results in a compact size of the overall system.

The practical application can be generated for a uniform shift-by-wire shift actuation, for which multiple different versions of actuation should be available. The type of signaling is not affected by the concept presented here. For example, it is possible to represent contact-dependent or non-contact sensors. The idea can be used for latching, as well as monostable actuation systems.

FIG. 3 shows a sectional view of a transmission device 104 according to an embodiment of the present disclosure. The transmission device 104 can involve a model of the embodiment of a transmission device 104 shown in FIG. 1 or FIG. 2.

The transmission device 104 comprises a transmission lever 108, which is pivoted about a first axis 222 for receiving the angle of activation of the selector lever 114. Furthermore, the transmission device 104 comprises a signal lever 112, which is pivoted bout a second axis 224 for providing a transducer angle for a transmitter element 330, for example, a magnet, of a sensor 332. Finally, the transmission device 104 comprises a drive device 110, by means of which a movement of the transmission lever 108 is transmitted to the signal lever 112. As a result, the angle of activation can be transmitted to the transducer angle of the signal lever 112. At the same time, it is possible to configure a force application point between the transmission lever 108 and the signal lever 112 to adjust a proportional value between the angle of activation and the transducer angle.

The drive device 110 comprises a coupling element 334 in the form of a pin and an, especially linear, guide unit for the coupling element 334. The coupling element 334 is arranged in a receptacle 336 on the transmission lever 108. At the same time, the coupling element can be connected with the transmission lever 108 in detachable and non-detachable manner. The guide unit of the drive device is arranged on the signal lever 112. Alternatively, a coupling element can be arranged in a receptacle on the signal lever 112 and the guide unit on the transmission lever 108.

The transmission lever 108 comprises at least one further receptacle 336, here three receptacles 336. The receptacles 336 are designed in the form of pocket holes or drill holes. The receptacles 336 are arranged radially to the rotation axis of the transmission lever. The receptacles 336 are arranged at different spaces from the first axis 222. The coupling element 334 is arranged in one selected receptacle 336. Depending on the arrangement of the coupling element 334 in one of the receptacles 336, a different proportional value is adjusted between the angel of activation and the transducer angle.

A circuit board 338 is arranged next to the signal lever 112. At least one sensor 332 is arranged at the circuit board 338. The transmitter element 330 can be moved about the second axis 224 along a circular path over the circuit board 338 in a plane that is parallel in a tolerance range to the circuit board. According to this embodiment, the circuit board 338 has a plurality of sensors 332. The sensors 332 are arranged in a sensor field.

According to this embodiment, the transmission device 104 comprises a locking device 340. The locking device 340 blocks in a locked condition a movement of the transmission lever 108 or the signal lever 112. For this purpose, the locking device 340 engages in the locked condition in a locking recess of the transmission lever 108.

According to this embodiment, the transmission device 104 comprises a housing 342. The housing can consist of several parts. The axes 222, 224 are supported by the housing 342. As a result, the transmission lever 108 is supported by the housing 342 or pivoted about the first axis 222. Correspondingly, the signal lever 112 is supported by the housing 342 or pivoted about the second axis 224.
