Oil way circulation structure of brake

Abstract

The invention provides an oil way circulation structure of a brake, and belongs to the technical field of brakes. The oil way circulation structure solves the problem that the temperature of gear oilused for cooling a dynamic friction plate and a static friction plate of a brake in the prior art is too high. According to the oil way circulation structure of the brake, the brake comprises a shafthead, a hub arranged on the shaft head in a sleeving mode and a cylinder body arranged at the front end of the hub in a sleeving mode, the shaft head is connected with the hub through a bearing, a mounting cavity is formed in the cylinder body, and a brake pad arranged on the cylinder body and a friction plate arranged on the hub are arranged in the mounting cavity. The oil way circulation structure comprises a front oil cavity located in the front side of the bearing and a rear oil cavity located in the rear side of the bearing, the front oil cavity communicates with the rear oil cavity, andthe front oil cavity communicates with the mounting cavity. The oil way circulation structure further comprises an oil return hole located between the mounting cavity and the rear oil cavity, and theoil return hole is formed in the hub. The oil way circulation structure of the brake can prevent the situation that the sealing effect and the service life of a sealing piece are affected due to the fact that the temperature of the hydraulic oil in the mounting cavity is too high.

Description

technical field [0001] The invention belongs to the technical field of brakes, in particular to an oil circuit circulation structure of a brake. Background technique [0002] In the process of coal mining, rail cars are usually used to transport the coal in the mine to the outside of the mine. After the coal is stacked on the rail cars, the weight of the rail cars is very heavy. When the rail cars drive out of the mine, the rail cars need to be carried out Braking, because the rail car has a very large kinetic energy after running, generally a hydraulic brake is installed on the rail car to brake the rail car. [0003] For example, China Patent Network discloses a wet brake that prevents oil from leaking through holes [Application Publication No.: CN109707766A], which includes a hub, a brake housing, a hollow shaft head, a rotating piston, an elastic member, a dynamic friction plate, a static friction plate and an intermediate disc. The outer circumference of the hollow sha...
