This invention also includes a regulation device composed of an end cover, a test device and regulation bolts, and the cover is connected with the baffle by the bolt and a test device testing the space between the cover and the baffle is set on the end cover connected to the shell.

Description

technical field [0001] The invention relates to the field of hydraulic brakes, in particular to disc hydraulic brakes with adjustable braking force. Background technique [0002] At present, disc hydraulic brakes that can provide large braking torque, reliable braking, and stability have been increasingly used in large construction machinery and industrial equipment. Its main working parts include: dynamic friction plate, static friction plate, hydraulic components, springs, etc. The principle is to use the interaction between the spring force and the hydraulic pressure to realize the normally closed and normally open states. The existing disc hydraulic brakes have the following problems. One is that the components are complex in structure and expensive; For braking, the wear rate of the friction plate is high, and it is difficult to detect the friction plate, and it is difficult to judge the amount of wear; the fourth is that the braking force cannot be adjusted, and ther...
