Problems solved by technology

[0003] The existing wet brakes mostly use two sealing rings, a piston and a sealing chamber for the driving of the cylinder body. The high-pressure oil pushes the piston, and the piston pushes the dynamic and static friction plates to achieve braking. However, in the process of continuous braking, it is easy to cause braking. The temperature of the piston seal is too high to cause aging failure. At the same time, the temperature of the brake fluid is too high to vaporize in the brake pipeline to generate air resistance, which makes the sealing ring lose its sealing effect and causes oil leakage, which in turn leads to brake failure.

Abstract

The invention discloses a gap-adjustable multi-head threaded force-increasing wet brake. The brake comprises a connecting disc, a pad disc and static friction plates, movable friction plates and a supporting disc; a brake pressing disc and a gear ring pressing plate are further arranged between the friction plate set and the supporting disc, the two end faces of the brake pressing disc and the gear ring pressing disc are provided with multi-head threads which are matched with each other, the other end of the gear ring pressing disc is provided with an outer gear ring, the outer gear ring is meshed with one end, provided with a gear, of a gear shaft, and the other end of the gear shaft penetrates through a shaft hole in the supporting disc and is connected with an air chamber through a rocker arm. The brake is simple in structure, a multi-head threaded structure is adopted to replace a traditional oil pressure piston, the force-increasing brake is realized, after the friction plates areabraded, the gear shaft can be rotated manually, the distance between the friction plates is adjusted so as to guarantee the reliability of braking, and the service life of the brake can be prolonged.

Description

technical field [0001] The invention relates to the technical field of construction machinery brakes, in particular to a wet brake with adjustable clearance and multi-thread booster. Background technique [0002] The brake is one of the important components on the bridge. The brake can be divided into dry brake and wet brake. Since the wet brake is closed, it is not affected by the external environment, the braking torque is stable, and it has an explosion-proof function. Widely used in other fields. [0003] The existing wet brakes mostly use two sealing rings, a piston and a sealing chamber for the driving of the cylinder body. The high-pressure oil pushes the piston, and the piston pushes the dynamic and static friction plates to achieve braking. However, in the process of continuous braking, it is easy to cause braking. The temperature of the piston seal is too high to cause aging failure. At the same time, the temperature of the brake oil is too high to vaporize in the...
