Driving shaft locking device, power-driven system and vehicle

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, a planet carrier, the first drive shaft and the first joint part synchronously rotate, the first joint part can move in the axial direction relative to the first driving shaft, the second driving shaft, the second joint part and a sun wheel synchronously rotate, the joint part driving device comprises a driving pin and a driving part, the driving pin can rotate around the sun wheel along with a gear ring and can axially move relativeto the gear ring, the driving part is used for driving the driving pin to drive the first jointing part to move in the direction close to the second jointing part in the axial direction so as to enable the first joint part to be connected to the second joint part, and a rolling structure is arranged at least one end of the drive pin. According to the driving shaft locking device, the two drivingshafts 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...
