Description

Technical Field

[0001] The utility model relates to the technical field of axle housings, in particular to an interrupted integrated drive axle housing. Background Art

[0002] The axle housing is the base for installing the main reducer, differential, half-axle and wheel assembly. Its main function is to support and protect the main reducer, differential and half-axle. Generally speaking, the axle housing of an ordinary non-disconnecting drive axle is a rigid hollow beam supported on the left and right drive wheels. The main reducer, differential, half-axle and other transmission parts are installed in it. The axle housing is connected to the frame or carriage through a longitudinal leaf spring. It is an important part of the drive axle and one of the main components of the travel system. The drive axle housing should have sufficient strength and rigidity, small mass, and be easy to disassemble and adjust the main reducer.

[0003] The inner cavity of the bridge housing body is filled with lubricating oil, which can lubricate the gears in the inner cavity of the bridge housing body to reduce the wear of the gears when they rotate. However, although the rotation of the gears is protected by the lubricating oil, a certain amount of iron filings will still be generated on the surface of the gears during rotation. The iron filings fall into the lubricating oil, so that the iron filings will accelerate the wear of the gears when the gears rotate. When the lubricating oil is replaced, after the oil drain bolt is separated from the oil drain through hole, the lubricating oil will be discharged from the oil drain through hole in sequence, causing the lubricating oil to adhere to the hands, which is very inconvenient to operate. In order to solve the above problems, an interrupted integrated drive bridge housing is proposed in the present application. Utility Model Content

The oil drain hole can be closed by abutting the lower pressure pad and the rubber pad. When replacing the lubricating oil, the lubricating oil can be prevented from adhering to the hands after the oil drain bolt is disassembled.
