Description

A New Type of Rotating Rapid Air Release Structure

technical field

The present invention relates to the technical field of auto parts, in particular to a novel rotating and fast deflating structure.

Background technique

The clutch wheel cylinder is a part of the braking system. Its main function is to push the brake pads, and the brake pads rub the brake drum to reduce the speed and stop the vehicle. It is an indispensable and important part in the braking system.

However, the existing clutch wheel pump is not designed with the auxiliary function of self-exhausting. When it is assembled and assembled in the car factory, it is evacuated through the vacuum equipment of the car factory, evacuated through the oil cup port of the brake master cylinder, and then quickly filled with oil. The interior is a blind space, and it is difficult to remove the gas. Therefore, it is necessary to repeatedly evacuate the gas before it can be discharged. However, because there is no equipment for exhausting in the after-sales market, it is difficult to replace it. Although a vent screw structure is currently designed for venting (for example, the solution adopted in the application number: CN201720701390.4), a torque wrench needs to be used to apply the specified torque to lock the vent screw when installing the vent screw; It is necessary to use a torque wrench of the appropriate specification, which is inconvenient to disassemble and inefficient.

In view of this, the inventor specially designed a new type of rotating and rapid deflation structure, and this case came into being.
