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

Embodiment Construction

[0025] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0026] Combine below Figure 1-Figure 14 The differential 100 according to the embodiment of the present invention will be described in detail. The differential 100 can be used for inter-wheel differential or inter-axle differential. Taking the inter-wheel differential as an example, the differential 100 can enable The left and right driving wheels roll at different angular velocities when the vehicle is turning or driving on uneven roads, so as to ensure pure rolling motion between the driving wheels on both sides and the ground...

Abstract

The invention discloses a differential mechanism and a vehicle. The differential mechanism comprises two planetary gear mechanisms, a power joint device and a joint part driving device. Gear rings service as power output ends, input parts are include, the input parts and two planet carriers are coaxially arranged, and the input parts and the two planet carriers are in linkage. The power joint device comprises a first joint part body and a second joint part body, the first joint part body is connected with one of the two gear rings, the second joint part body and the two planet carriers synchronously rotate, and the two planet carriers form a power input end of the differential mechanism. The joint driving device comprises a driving needle and a driving part, the driving part is arranged tobe used for driving the driving needle to drive the second joint part body to move in the axial direction to the direction close to the first joint part body, and therefore the second joint part bodyis connected with the first joint part body. Therefore, two half shafts can be locked by the differential mechanism, and the escape capacity of the vehicle can be improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a differential and a vehicle with the differential. 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 [0003] The present invention aims to solve one of the technical problems in the related art a...
