Detailed Description

As shown in fig. 1 and 2, the present embodiment includes: an input assembly 19 for two times vertical torque transmission, and a locking mechanism 18, a pawl 15 and a parking gear 16 arranged in the same plane, wherein: the input member 19, the locking mechanism 18, and the pawl 15 are connected by the connector 7, and the pawl 15 is connected to the connector 7 by the connector shaft 8 and engaged with the parking gear 16.

As shown in fig. 3, the input module 19 includes: the shift motor 1, motor shaft 2, the axle of shifting 3, castellated plate 4 and the connecting rod 6 of shifting that connect gradually, wherein: the gear shifting connecting rod 6 is connected with the connector 7, and the motor shaft 2 and the gear shifting shaft 3 are connected through a flat square structure to adapt to gear shifting motors 1 of different specifications.

As shown in fig. 4, the locking mechanism 18 includes: locking axle base 10, locking axle spring 11, locking axle 12, locking conical head 13 and locking locating piece 14, wherein: the locking shaft base 10, the locking shaft 12, the locking conical head 13 and the locking positioning block 14 are sequentially connected, the locking shaft spring 11 is arranged on the outer side of the locking shaft 12, the locking shaft base 10 is connected with the connector 7 through the driven connecting rod 9, and the locking conical head 13 is in contact with the pawl 15.

As shown in fig. 5, the top of the locking shaft 12 is provided with a boss 17 and the radius of the boss is larger than the inner hole of the locking conical head 13 so as to hard connect the locking shaft 12 and the locking conical head 13 and facilitate quick P shift.

As shown in fig. 3, the castellated plate 3 is provided with a resilient locating pin 5 for controlling the angle of rotation.

The castellated plate 3 corresponds P, R, N, D and S fender from left to right in turn.

The above device works by the following ways: the gear shifting motor 1 outputs power, the torque output by the motor shaft 2 can be modularly designed through one-time flat square structure transmission, the corresponding interface of the gear shifting shaft 3 can be adjusted when the gear shifting motor is matched with motors of different specifications, and the application universality of the device is improved. As shown in fig. 6, the torque transmitted from the shift motor 1 to the shift shaft 3 drives the toothed plate 4 to rotate clockwise around the shift shaft 3, so that the torque direction is vertically transmitted for the first time, the toothed plate 4 drives the shift link 6 to rotate, the vertically upward force on the shift link 6 rotates clockwise around the connector shaft 8, then the driven link 9 drives the locking mechanism 18 to move horizontally to the right, the vertical transmission for the second time is generated here, the internal space is saved by the two vertical transmissions, and the axial space occupation is further reduced.
