Differential shell

Abstract

A differential shell comprises a first shell (10) and a second shell (20) fixedly connected with each other. A first oil port (11) arranged on the first shell (10) penetrates from the outer periphery to the inner periphery along the periphery of the first shell (10); the extension direction of the first oil port (11) deviates from the central line of the first shell (10); a second oil port (21) arranged on the second shell (20) penetrates from the outer periphery to the inner periphery along the periphery of the second shell (20); the extension direction of the second oil port (21) deviates from the central line of the second shell (20); and one of the first oil port (11) and the second oil port (21) is an oil outlet and the other one is an oil inlet. In the differential shell, by improving a lubricating oil port, lubricating oil can be forcibly fed in or discharged from the differential shell, thereby enhancing circulation of the lubricating oil in the differential shell, reducing abrasion of parts in the differential shell, and prolonging the service life of the differential.

Description

technical field [0001] The invention relates to the field of drive axles of vehicles, in particular to a differential case suitable for drive axles. Background technique [0002] As we all know, when a car is turning or driving on an uneven road, the differential can allow the left and right wheels to rotate at different speeds, making the wheels purely roll on the ground. Wherein, the planetary gears and the side gears are meshed in the differential housing. In order to reduce wear and tear, it is necessary to inject lubricating oil into the differential housing to lubricate the parts inside the differential housing. common way. [0003] Such as Figure 1A and Figure 1B Shown is a differential case in the prior art. It can be seen that the oil inlet hole 1 and the oil outlet hole 2 for filling lubricating oil are respectively provided on the left and right housings of the differential, and the extension direction of the oil inlet hole 1 and the oil outlet hole 2 on the ...

AI Technical Summary

Problems solved by technology

However, since the web 3 of the differential housing needs to occupy a large space, when the housing space of the drive axle is small, the web 3 is not easy to arrange

Moreover, the working torque of the differential is large, and the differential case needs to be manufactured by forging process. After adding the web plate 3, the structure of the differential is relatively complicated, which leads to the complicated forming process of the blank of the differential case.
