Multi-disk wet-type brake for loading machine

Abstract

The invention relates to a multi-disk wet-type brake for a loading machine, and belongs to the technical field of mechanical braking. The multi-disk wet-type brake for the loading machine is characterized in that: a planet wheel carrier is arranged on a wheel shell; a check ring, a left bearing plate, a right bearing plate, friction sheets and braking sheets are arranged in a brake shell; the check ring is used for limiting the left bearing plate, the right bearing plate and the friction sheets and the braking sheets which are arranged at intervals in the brake shell; the brake shell is connected with an oil cylinder and a supporting shaft through bolts to form a whole; the supporting shaft is fixed with a bridge shell; the friction sheets which are arranged at intervals are connected with the wheel shell through a spline, and can move along an axial direction; the braking sheets which are arranged at intervals, the left bearing plate and the right bearing plate are connected with the brake shell through splines, and can move along the axial direction; and a piston of the oil cylinder can move along the axial direction to push the bearing plates, and is provided with a resetting mechanism. The multi-disk wet-type brake has the advantages of simple structure, convenience for assembly and disassembly, steady braking property, safe and reliable performance, high sealing and heat dissipation performance, low cost, long service life and the like.

Description

technical field [0001] The invention belongs to the technical field of mechanical brakes, in particular to a multi-disc wet brake for a loader. Background technique [0002] At present, the brakes for drive axles of construction machinery loaders generally use dry-type caliper disc brakes. Compared with wet brakes, caliper-disc brakes have simple structure and stable braking performance, but they have obvious disadvantages: 1. Because they are always If it is exposed to the outside, the brake disc is easy to stick to oil and rust, which affects the braking effect and poses a great safety hazard; 2. The friction braking area of ​​a single disc is small, the unit pressure is high, the working temperature is high, and the heat dissipation condition is poor Friction material performance requirements are high. The shortcomings of dry brakes that are difficult to overcome limit the scope of use of the corresponding drive axles, and the research and development of wet brakes for d...

[0002] At present, the brakes for drive axles of construction machinery loaders generally use dry-type caliper disc brakes. Compared with wet brakes, caliper-disc brakes have simple structure and stable braking performance, but they have obvious disadvantages: 1. Because they are always If it is exposed to the outside, the brake disc is easy to stick to oil and rust, which affects the braking effect and poses a great safety hazard; 2. The friction braking area of ​​a single disc is small, the unit pressure is high, the working temperature is high, and the heat dissipation condition is poor Friction material performance requirements are high

As a fully enclosed structure, the existing wet brake has technical problems such as complex structure, poor braking performance, unstable operation, and short service life.
