Hydraulic motor integrating wet brake

Abstract

The invention discloses a hydraulic motor integrating a wet brake. The hydraulic motor integrating the wet brake comprises a hydraulic motor body and a brake body, wherein the brake body is arranged on the tail portion of the hydraulic motor body, the brake body comprises a brake outer shell, braking pistons, a driving friction plate, a driven friction plate, reset springs, first reset spring bases, second reset spring bases and a transition disk, wherein the braking pistons, the driving friction plate, the driven friction plate, the reset springs, the first reset spring bases, the second reset spring bases and the transition disk are arranged in the brake outer shell. Internal teeth of the transition disk are meshed with external teeth of a transmission shaft of the hydraulic motor body, and the driving friction plate can rotate along with the transmission shaft of the hydraulic motor body when the transmission shaft rotates. When braking is not carried out, the driving friction plate and the driven friction plate are in a separated state. When braking is carried out, the braking pistons overcome force of the reset springs to move left, and braking begins when the reset springs make contact with the driving friction plate and the driven friction plate. Due to the facts that a braking mode of dynamic braking is adopted, and braking torque changes along with braking pressure in a linear mode, the slowly-opened function and the slowly-closed function can be achieved, and due to the fact that a braking cooling oil port is formed, the defect that a motor is poor in heat dissipation capacity can be overcome.

Description

technical field [0001] The invention relates to a hydraulic motor integrating a wet brake. Background technique [0002] At present, the service braking of hydraulic motors mainly relies on external drum brakes or disc brakes. Although drum brakes and disc brakes are widely used in the field of vehicle braking, and the technology is very mature, they are relatively large in size, complex in structure, and frequently replaced by friction linings. At the same time, the braking working surface is directly exposed, and water, sand, gravel, mud, dust and other debris on the driving road enter the working surface, making the braking effect worse, especially in harsh working conditions such as underground, mines, and disaster areas. , but also formed a huge security risk. [0003] In recent years, the application of wet braking technology has become more and more extensive, and the technology has become more and more mature. Its advantages are mainly reflected in its simple struc...
