Embodiment Construction

[0017] The present invention provides a differential, which can bear a relatively high rotational speed difference and can bear relatively large torque. The following will refer to Figure 1 to Figure 3 Describe in detail.

[0018] refer to Figure 1 to Figure 2 , The differential according to the exemplary embodiment may include a planetary gear shaft, a planetary gear assembly and a load sharing assembly disposed on the planetary gear shaft, an output assembly, and a case assembly.

[0019] The planetary gear shaft 17 may have a cross-shaped structure, and have a first shaft and a second shaft disposed opposite to each other and a third shaft and a fourth shaft disposed opposite to each other, the first shaft may have a cross-shaped structure from the planetary gear shaft 17 A shaft body, a shaft shoulder, and a shaft neck that extend outward from the center of the shaft, and the size of the shaft shoulder is larger than the size of the shaft body, and the size of the shaf...

Abstract

The invention relates to a differential mechanism. The differential mechanism comprises a planet gear shaft, a planet gear assembly, a uniform load assembly, an output assembly and a shell assembly, wherein the planet gear assembly and the uniform load assembly are arranged on the planet gear shaft. By means of the planet gear assembly and the uniform load assembly, the differential mechanism can bear high rotating speed difference and large torque.

Description

technical field [0001] The invention belongs to the field of vehicles, in particular to a differential for vehicles. Background technique [0002] The vehicle's differential can make the left and right (or front and rear) drive wheels rotate at different speeds, so that the left and right wheels can roll at different speeds when the vehicle is turning or driving on uneven roads. However, the existing differentials are generally unable to bear a high rotational speed difference, and cannot transmit a large torque, so that its application to vehicles is limited. Contents of the invention [0003] The purpose of the present invention is to propose a differential gear, which can withstand a relatively high rotational speed difference and a relatively large torque. [0004] Specifically, it is achieved through the following technical means: [0005] A differential, comprising: a planetary gear shaft having a cross-shaped structure, and having a first shaft and a second shaft ...
