A built-in multi-plate wet brake

Abstract

The invention relates to the technical field of brakes, in particular to a built-in multi-plate wet brake, which includes a housing and a sealing plate, the housing and the sealing plate are fixedly connected by bolts, and the housing is provided with a plurality of dynamic friction plates and a plurality of A static friction plate, and a plurality of dynamic friction plates and a plurality of static friction plates are stacked at intervals inside the housing, a brake push rod is provided on the top of the sealing plate, the brake push rod runs through the top of the sealing plate, and the bottom end of the brake push rod Fixed welding with sealing plate. The internal structure of the brake can be simplified by setting the elastic diaphragm, and the setting of the elastic diaphragm makes the return time of the friction plate shorter and the separation is more thorough. In addition, the design of the buffer structure makes the contact pressure of the friction plate gradually increase, changing the direct increase in the past. The unique braking method prevents the occurrence of tire locking, not only improves the safety of the brake, but also greatly reduces the damage of the friction plate. The structure is simple, the braking effect is better, and it is suitable for promotion.

Description

technical field [0001] The invention relates to the technical field of brakes, in particular to a built-in multi-plate wet brake. Background technique [0002] Automobile brakes are one of the most important components of automobiles, and their braking performance directly affects the safety of automobiles. Brakes are used to slow down the automobile or stop the automobile within the shortest distance according to demand. They are mainly divided into drum type and disc type. . Although the drum brake vehicle is low in cost and dustproof, it is large in size and heavy in weight, and is not easy to dissipate heat. Disc brakes have good heat dissipation, good braking stability, and small size and weight. Among the disc brakes, the multi-disc wet brake is a disc brake whose friction plates work in an oil-immersed closed environment. It has the advantages of large braking torque, long service life, strong anti-fading and anti-pollution capabilities, and maintenance-free. Theref...

Problems solved by technology

The arrangement of the helical spring will easily lead to an increase in the axial dimension of the brake housing, which will lead to an increase in the size of the brake and a complex structure. When the helical spring is released, the piston will be pushed back to its original position, which will take a long time to return and the separation of the friction plate will not be complete.

The uneven distribution of the compression force of the coil spring will also cause the brake to be unstable and affect the braking performance

Therefore, we designed a joint action of the dynamic and static friction plates by squeezing the friction disc with the elastic diaphragm, and the separation of the inner and outer friction plates by means of the diaphragm spring can ensure fast and complete separation of the inner and outer friction plates, thereby improving braking reliability. The elasticity of the disc itself is too large, and a slight bending will generate a large amount of elastic recovery force. Squeezing the friction disc can easily cause the wheel to lock. have an accident
