Problems solved by technology

[0002] In the related art, the drive axle installed in the vehicle has a large volume and weight, which is not only inconvenient to assemble, but also takes up a large assembly space when the drive axle is installed, thereby increasing the difficulty of assembling other parts in the vehicle. The layout form is also relatively complicated, which greatly reduces the transmission efficiency of the drive system

Abstract

The invention discloses a drive axle and a vehicle with the drive axle. The drive axle comprises an axle housing assembly, a motor, a planetary reduction gear and a differential mechanism. The motor comprises a motor shaft and a motor shell, the motor shaft is a hollow shaft, and the motor shell is fixed to the axle housing assembly. The planetary reduction gear comprises an input sun gear, an inner gear ring and an output planet carrier, wherein the input sun gear is connected with the motor shaft, the inner gear ring is fixed to the axle housing assembly, and the output planet carrier is theoutput end of the planetary reduction gear. The differential mechanism is arranged on the axle housing assembly and comprises a differential mechanism shell and two half axle gears, wherein the differential mechanism shell and the output planet carrier are integrally formed, the two half axle gears are connected with two wheel end half axles respectively, and one wheel end half axle penetrates through the motor shaft. According to the drive axle, the output planet carrier in the planetary reduction gear and the differential mechanism shell of the differential mechanism are arranged to be an integrally-formed part, such that the light weight and function centralized integrated design of the drive axle can be achieved, and the assembly space of a chassis is greatly saved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a drive axle and a vehicle with the same. Background technique [0002] In the related art, the drive axle installed in the vehicle has a large volume and weight, which is not only inconvenient to assemble, but also takes up a large assembly space when the drive axle is installed, thereby increasing the difficulty of assembling other parts in the vehicle. The layout form of the drive system is also relatively complicated, which greatly reduces the transmission efficiency of the drive system. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, it is an object of the invention to propose a transaxle which has the advantage of being compact. [0004] The present invention also proposes a vehicle provided with the above drive axle. [0005] The driving axle according to the embodim...
