Wet type multi-disc brake

Abstract

The invention discloses a wet type multi-disc brake integrating functions of speed lowering, braking and parking. The wet type multi-disc brake which is mainly applicable to the harsh-condition and inconvenient-to-maintain brake systems of various machines is characterized in that parts are mounted by using a shell as a base, the brake is fixed by the connection of a stud and an axle, and a drive wheel is connected with a hub through a connecting bolt to synchronously rotate with car wheels; each friction plate working cavity is a sealed cavity which can effectively deal with external harsh work conditions, circulation cooling oil is fed into the sealed cavity, temperature rise can be lowered effectively, consumption is reduced, stable work performance is achieved, slight abrasion is achieved, and adjustment is generally not needed during use; each friction plate is annular and large in working area, the multi-disc structure is used, and large brake torque can be obtained under small gasket pressure; the brake torque can be adjusted by changing the number of friction pairs, and friction pair standardization can be achieved easily; good radiating and cooling effect, low working temperature and long service life are achieved, and the service life of the wet type multi-disc brake is generally 3-5 times of that of a dry type brake.

Description

technical field [0001] The invention relates to a wet multi-disc brake integrating retarding, braking, parking and other functions, which is mainly used for the braking system of various machines with harsh conditions and inconvenient maintenance, such as engineering machinery and mining machinery. , heavy trucks, loaders, etc. Background technique [0002] Traditional construction machinery brakes generally use dry friction plates, which are exposed to brake, relying on natural cooling or air cooling, which cannot effectively solve the problem of frequent braking temperature rise and the impact of external harsh environments such as high dust during use. Intensity, brake failure is prone to occur during long-term operation, bringing potential safety hazards, frequent maintenance and frequent replacement of friction plates are required, which cannot meet the needs of users. Contents of the invention [0003] In view of the above-mentioned problems, in order to solve the p...

[0002] Traditional construction machinery brakes generally use dry friction plates, the friction plates are exposed for braking, relying on natural cooling or air cooling, which cannot effectively solve the problem of frequent braking temperature rise and the impact of external harsh environments such as high dust during use. Intensity, brake failure is prone to occur during long-term operation, which brings potential safety hazards, frequent maintenance and frequent replacement of friction plates are required, which cannot meet the needs of users
