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-driven system and a vehicle. The driving shaft locking device comprises a planetary gear mechanism, a first driving shaft, a second driving shaft and a power joint device and further comprises a joint part driving device, the power joint device comprises a first joint part and a second joint part, the first driving shaft is connectedto a sun wheel and is further configured to synchronously rotate with the first joint part, the second driving shaft is connected to a gear ring and is further configured to synchronously rotate withthe second joint part, the joint part driving device comprises a driving pin and a driving part, the driving pin can rotate along with the center axis of the sun wheel along with a planet carrier andcan move axially, and the driving part is used for driving the driving pin to drive the second joint part to move in the direction close to the first joint part in the axial direction so as to enablethe second joint part to be connected to the first joint part. According to the driving shaft locking device, the two driving shafts can be locked, and the escape capability of the vehicle can be improved.

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...
