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 and a power-driven system and a vehicle. The driving shaft locking device comprises a planet gear mechanism, a first driving shaft, a second driving shaft, a power joint device, and a joint part driving device. The power joint device comprises a first join part and a second joint part, a planet frame and the first driving shaft rotate with thefirst joint part synchronously, the first joint part can move in the axial direction relative to the first driving shaft, and the second driving shaft, the second joint part and a sun wheel rotate synchronously. The joint part driving device comprises a driving needle and a driving part, the driving needle is arranged to be capable of rotating around the center axis of the sun wheel along a gearring and move in the axial direction relative to the gear ring, and the driving part is used for driving the driving needle to drive the first joint part to move to the direction close to the second joint part in the axial direction, so that the first joint part is in joint with the second joint part. The driving shaft locking device can lock two driving shafts, and the off-the-hook capacity 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...
