Problems solved by technology

[0002] In the related technology, the new energy vehicle adopts a distributed drive mode, and two motors drive the wheels on both sides respectively. The speed and torque of the left and right wheels can be independently adjusted by the controller, which cancels the differential. In some slippery road conditions, it is still necessary to lock the left and right axle shafts to improve vehicle passability
If the traditional electric locking differential is applied to distributed drive new energy vehicles, the differential function of the differential will be wasted, and the traditional electric locking differential has a complex structure and many parts. takes up more space

Abstract

The invention discloses a driving shaft locking device, a power drive system and a vehicle. The driving shaft locking device includes: a planetary gear mechanism; The joint part, the first drive shaft is connected with the sun gear, the first drive shaft rotates synchronously with the first joint part, the second drive shaft is connected with the ring gear, and the second drive shaft rotates synchronously with the second joint part; it includes: a drive needle and In the manual driving device of the manual driving part, the driving pin can rotate with the planetary carrier around the central axis of the sun gear and can move axially relative to the planetary carrier. The manual driving part is configured to drive the driving pin to drive the second engaging part along the Move toward the direction close to the first engaging portion, so that the second engaging portion engages the first engaging portion. In this way, the drive shaft locking device can lock the two drive shafts, which can improve the ability of the vehicle to get out of trouble.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a drive shaft locking device for a vehicle, a power drive system with the drive shaft lock device, and a vehicle with the power drive system. Background technique [0002] In the related technology, the new energy vehicle adopts a distributed drive mode, and two motors drive the wheels on both sides respectively. The speed and torque of the left and right wheels can be independently adjusted by the controller, which cancels the differential, but in a In some slippery road conditions, it is still necessary to lock the left and right axle shafts to improve vehicle passability. If the traditional electric locking differential is applied to distributed drive new energy vehicles, the differential function of the differential will be wasted, and the traditional electric locking differential has a complex structure and many parts. Take up more space. Contents of the invention [00...
