Abstract

The invention discloses a differential mechanism, a drive axle with the same and a vehicle. The differential mechanism comprises a shell, a connection shaft, a planetary gear and a half axle gear. A holding space is defined in the shell. The connection shaft is arranged in the holding space and is fixed to the shell so as to rotate synchronously along with the shell. The planetary gear is arrangedon the connection shaft in a sleeving mode and can rotate relative to the connection shaft. A first gasket is arranged between the planetary gear and the shell. The surface, toward the planetary gear, of the first gasket is provided with a first oil passing groove. The half axle gear is arranged in the holding space and is in meshing fit with the planetary gear. Through the differential mechanism, the dry abrasion phenomenon between the first gasket and the planetary gear can be reduced, reliability of the differential mechanism is improved, and the service life of the differential mechanismcan be prolonged.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a differential, a drive axle with the same, and a vehicle. Background technique [0002] In the differential of the related art, the lubricating effect between the first gasket and the planetary gear is poor, so dry grinding phenomenon easily occurs between the first gasket and the planetary gear, thereby affecting the reliability of the differential and service life. 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 differential gear that can reduce the dry grinding phenomenon between the first washer and the planetary gears. Improving the reliability of the differential is beneficial to prolonging the service life of the differential. [0004] The present invention also proposes a drive axle, including the abo...
