Example Embodiment

[0037] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary, and are intended to explain the present invention, but should not be construed as limiting the present invention.

[0038] Reference below Figure 1-Figure 5 The differential gear 100 for a vehicle according to an embodiment of the present invention will be described in detail. The differential gear 100 can lock the two semi-axles when the vehicle is slipping, so as to improve the escape ability of the vehicle.

[0039] Such as figure 1 , figure 2 with image 3 As shown, the differential gear 100 according to the embodiment of the present invention may include: a housing 10, a power coupling device 20, and a coupling portion driving device 30. The power coupling device 20 can be used for the housing 10 and a side gear, and the coupling portion ...

Abstract

The invention discloses a differential and a vehicle. The differential comprises a shell, a power joint device and a joint part driving device; the shell is internally provided with a left half axle gear, a right half axle gear, a planet wheel and a planet wheel axle; the planet wheel is rotatably installed on the planet wheel axle, and engaged with the left half axle gear and the right half axlegear; the power joint device comprises a first joint part and a second joint part, and the first joint part is connected to the left half axle gear or the right half axle gear; the second joint part is rotated with the shell synchronously, and can be axially moved relative to the shell; the joint part driving device comprises a driving needle and a driving part, and the driving part is used for driving the driving needle to drive the second joint part to axially move in the direction close to the first joint part, so that the second joint part is in joint with the first joint part. In this way, two half axles can be locked by the differential, and the vehicle ability of getting out of trouble 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 art, the structure of the electric locking differential is complicated, there are many parts, and it takes up a lot of space, which makes the cost of the differential high, and the control is difficult, and the implementation process is cumbersome. In addition, the many parts also lead to The assembly is difficult, the assembly efficiency is low, and the space utilization rate of the vehicle is also reduced. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. For this reason, the present invention proposes a differential, which has a simple structure, reliable functions, and can improve the ability of the vehicle to get out of trouble. [0004] The invention further proposes a vehicl...
