Embodiment Construction

[0011] The present invention will be further described below through specific embodiments. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, some modifications and improvements can also be made, and these should also be regarded as belonging to the present invention. protection scope of the invention.

[0012] like figure 1 As shown, the parking brake includes a spring 1, an end cover 2, a brake piston 3, a brake disc 4, a friction plate 5, a sealing ring 6 and a brake housing 7, and the cavity formed between the brake piston 3 and the transmission shaft There is a brake disc 4 and a friction plate 5 used in conjunction with it. Both the brake piston 3 and the brake disc 4 are connected to one end of the spring 1, and the other end of the spring 1 is fixed on the end cover 2; on the brake piston 3 is provided with a brake housing 7 connected to the end cover 2 on the outer periphery, and a seal...

Abstract

The invention discloses a parking brake, and belongs to the technical field of brakes. The parking brake comprises a spring, an end cover, a brake piston, a brake puck, a friction plate and a brake shell, wherein the brake puck and the friction plate are matched for use in a cavity formed by the brake piston and a transmission shaft. The brake piston and the brake puck are both connected with one end of the spring, the other end of the spring is fixed on the end cover, and the brake shell connected with the end cover is arranged on the periphery of the brake piston. The brake puck is connected with the brake shell through an outer spline, the friction plate is connected with the transmission shaft through a spline shaft, the brake shell is of a full-seal structure, and cooling oil liquid is filled in the brake shell. The brake not only avoids influence of water, dust, impurities and the like, but also is rapid and stable in a brake process, improves brake moment of force, and reduces wastage and maintaining costs of equipment.

Description

technical field [0001] The invention belongs to the technical field of brakes, in particular to a parking brake. Background technique [0002] The parking brake is used to stabilize the vehicle after the vehicle has come to a complete stop, so as to avoid accidents caused by rolling when the vehicle is parked on a slope. When working underground in coal mines, higher requirements are placed on the parking brake, which requires a large braking torque and can adapt to harsh working environments. The performance of the traditional parking brake is unstable, and the equipment loss is relatively large. Frequent maintenance of the equipment is required, which increases the production cost. Contents of the invention [0003] Purpose of the invention: Aiming at the deficiencies in the prior art, the purpose of the invention is to provide a parking brake, which can not only adapt to the harsh working environment in coal mines, but also run smoothly and reliably, with low equipment...
