Abstract

The invention discloses a drive axle and a vehicle with the same. The drive axle comprises a motor assembly which comprises a motor shaft; an axle housing assembly which comprises an axle housing cavity; and a speed reducing device which is arranged in the axle housing cavity. The motor shaft is connected with the speed reducing device, a planet wheel and a first connecting shaft are arranged in the speed reducing device, the first connecting shaft penetrates through the planet wheel and is connected with the planet wheel through a roller bearing, and an oil inlet channel is formed in the first connecting shaft so that the axle housing cavity can be communicated with the interior of the speed reducion device. According to the drive axle, all components in the speed reducing device can be lubricated, the reliability of the drive axle is improved, and the service life of the drive axle is prolonged.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a drive axle and a vehicle with it. Background technique [0002] In the drive axle of the related art, the lubricating effect between the components inside the reduction gear is poor, which affects the reliability and service life of the drive axle to a certain extent. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, an object of the present invention is to provide a driving axle, which can lubricate the components in the reduction gear, improve the reliability of the driving axle, and prolong the service life of the driving axle. [0004] The present invention also proposes a vehicle, including the above drive axle. [0005] The driving axle according to the embodiment of the present invention includes: a motor assembly, the motor assembly includes a motor sha...
