Description

Stable brake chamber Technical Field The utility model relates to the technical field of brake chambers, in particular to a stable brake chamber. Background The braking air chamber is also called a branch pump, and the function of the braking air chamber is to convert the pressure of compressed air into mechanical force for rotating a braking cam shaft, so that braking action is realized, when an automobile brakes, air enters the braking air chamber from an air inlet, the diaphragm deforms under the action of the air pressure, the push rod is pushed, the braking adjusting arm is driven, the braking cam is rotated, and the brake shoe friction plate is pressed towards the braking drum to generate braking. After the brake chamber in the market is used for a long time, the internal spring is easy to deform, because the spring continuously bears the compression and extension acting force in the frequent braking process and is in a high-stress state for a long time, the crystal structure of the metal material of the spring is gradually changed, so that fatigue phenomenon occurs, deformation is finally initiated, and the use of the brake chamber can be directly influenced after the spring is deformed. Disclosure of utility model The utility model aims to solve the defects in the prior art that after the brake chamber in the market is used for a long time, the internal spring is easy to deform, because the spring continuously bears the compression and extension acting force in the frequent braking process and is in a high-stress state for a long time, the crystal structure of a metal material of the spring is gradually changed, so that the fatigue phenomenon occurs, the deformation is finally initiated, the use of the brake chamber is directly influenced after the spring is deformed, and the brake chamber is stable.
