Description

Technical Field

[0001] This utility model relates to a parking lock actuator for operating a parking lock, the parking lock actuator having an electric drive motor, a transmission unit and an operating element. Background Technology

[0002] Parking lock actuators of the type described at the beginning are known from the prior art and ensure that parked cars do not roll away.

[0003] For this purpose, a locking pawl is provided, which is coupled to the operating element and can be selectively moved in the locking or unlocking direction, for example by means of a parking lock wheel.

[0004] The parking lock actuator is just one of many components in a motor vehicle. Therefore, due to structural space constraints, it is desirable to provide a parking lock actuator that is as compact as possible, with its components arranged in a space-saving manner. Utility Model Content

[0005] This task is solved using a parking lock actuator with the following characteristics.

[0006] In this invention, the second transmission unit is arranged on the end side of the drive motor and the motor shaft, wherein the operating element is arranged perpendicular to the longitudinal direction of the drive motor and perpendicular to the motor shaft.

[0007] It has been confirmed that this arrangement meets the specific functional requirements of the parking lock actuator and simultaneously enables improved compact installation of the actuator into the vehicle. The parking lock actuator according to this invention can be integrated into a motor vehicle with minimal structural space.

[0008] To further reduce the structural space, an improvement of this invention involves embedding the drive motor with the motor shaft, the first transmission unit, and the second transmission unit within the housing. Embedding these components of the actuator saves space because there are virtually no gaps or movement spaces between the components and the walls of the housing. This also facilitates the preferred arrangement of the second transmission unit within the housing, beside and to the side of the motor shaft.

[0009] A possible variation of this invention involves equipping the drive motor with a retaining element. The retaining element is preferably disposed on the end side of the drive motor and is preferably formed of sheet metal. It can have an arched shape and advantageously ensures reinforced retention of the drive motor within the housing.

[0010] Preferably, the length between the operating element and the end of the drive motor that is furthest from the drive motor and furthest from the second transmission unit is a maximum of 120 mm. Attached Figure Description

[0011] The present invention will be described below with reference to the accompanying drawings. The schematic diagrams are as follows:

[0016] Figure 1 A segment of a parking lock actuator with reference numeral 100 is shown and includes: a drive motor 10, a motor shaft 11 connected to the drive motor 10, a first transmission unit 12 connected to the motor shaft 11, and a second transmission unit 13 connected to the first transmission unit 12.

[0017] The motor shaft 11 includes a transmission mechanism designed to engage with the first transmission unit 12. The transmission mechanism of the motor shaft 11 is a worm gear drive. The worm gear drive has a helical thread 14, which engages with the first transmission unit 12.

[0018] As from Figure 1 It is further learned that the first transmission unit 12 has a transmission device 15 and a pinion 16. The transmission device 15 has multiple transmission teeth arranged around its periphery. The motor shaft 11 is in the form of a worm gear transmission device that is engaged with the transmission device 15 of the first transmission unit 12.

[0019] like Figure 1 As further disclosed, the pinion 16 protrudes vertically from the bottom of the first transmission unit 12 in one direction and is a transmission device with multiple teeth 17 designed to engage with the second transmission unit 13, which has a greater number of teeth 19 and is used for... Figure 2 The receiving portion 20 of the switching element 21 shown. For example... Figure 1 As further shown, the pinion 16 is smaller than the first and second transmission units 12, 13 in terms of its extension range.

[0020] The first transmission unit 12, arranged next to and to the side of the motor shaft 11, is also provided with a shaft element 18 mounted on the first transmission unit 12 and the pinion 16. The shaft element 18 extends through the geometric center point of the first transmission unit 12 and the pinion 16.

[0021] As also from Figure 1 It is understood that the drive motor 10 with motor shaft 11, the first transmission unit 12, and the second transmission unit 13 are embedded in the housing 18a.

As shown, the operating element 21 is mounted on the second transmission unit 13 and extends through its geometric center.

[0023] The second transmission unit 13 is arranged on the end side, that is, on the end side 27 of the motor shaft 11, and staggered on the end side 28 of the drive motor 10, wherein the operating element 21 is arranged perpendicular to the longitudinal direction of the drive motor 10 and the motor shaft 11.

[0024] The length between the operating element 21 and the end side 28 of the drive motor 10 that is away from the drive motor 10 and the side 29 that is away from the second transmission unit 13 is a maximum of 120 mm.

[0025] As from Figure 2 It was also learned that a retaining element 22 was provided for the drive motor 10, which was directly arranged on the end side 26 of the drive motor 10 and fastened to the parking lock actuator 100 by fastening devices 23 and 24.
