Oil chamber housing assembly

Abstract

The invention provides an oil chamber shell assembly. The oil chamber shell assembly comprises a top sealing cover (1), an oil chamber shell (2) and a bottom sealing cover (3), wherein the top sealing cover (1), the oil chamber shell (2) and the bottom sealing cover (3) are sequentially connected from top to bottom. The top sealing cover (1) is provided with an installation side wall (1.1) for installation of a proportional valve and provided with an air inflow channel (1.2) communicated with an air outlet of the proportional valve. An oil chamber (2.1) is formed in an inner cavity of the oil chamber shell (2), an inner oil way (2.2) with an oil inlet in the lower end communicated with the oil chamber (2.1) is arranged on the inner wall of the oil chamber (2.1), the air inflow channel (1.2) is communicated with the oil chamber (2.1), and a distance is reserved between the bottom wall of the bottom sealing cover (3) and the oil inlet in the lower end of the inner oil way (2.2). By the adoption of the oil chamber shell assembly, overall waste caused by local damage can be avoided, and parts are conveniently installed.

Description

technical field [0001] The invention relates to the technical field of hydraulic buffers, in particular to an oil chamber housing assembly. Background technique [0002] For the downhill deceleration of heavy trucks, it is often decelerated by the vehicle brake safety auxiliary device. The core component of the device is the hydraulic buffer, through which the speed of the main shaft of the vehicle can be reduced, thereby achieving downhill deceleration the goal of. [0003] The hydraulic buffer mainly includes an oil chamber shell, heat exchangers and working chamber shells respectively arranged on both ends of the oil chamber shell. The more common oil chamber housing is generally an integral structure, and when one of the parts, such as the top plate or the bottom plate, is damaged, the entire oil chamber housing is also scrapped, and the waste is serious. [0004] In addition, because the proportional valve needs to be directly installed on the oil chamber shell, and t...

Problems solved by technology

The more common oil chamber shell is generally an integral structure, and when one part, such as the top plate or bottom plate, is damaged, the entire oil chamber shell is also scrapped, and the waste is serious

[0004] In addition, because the proportional valve needs to be directly installed on the oil chamber shell, and the oil chamber shell is made of steel material, the overall volume is large and the weight is heavy. During the installation process of the proportional valve, the oil chamber shell needs to be It is not very convenient to move and flip
