Abstract

The present invention provides a caliper vent screw. The caliper vent screw comprises a one-way valve body and a gas storage structure, wherein a pressure-maintaining valve core is arranged at the bottom of the one-way valve body; a shell body is arranged on the outer side of the one-way valve body, and an O-shaped ring is disposed between the shell body and the pressure-retaining valve core; a pressure-retaining valve return spring is disposed in the middle of the one-way valve body, and a valve core of a one-way valve is disposed on the upper side of the pressure-retaining valve return spring; a one-way valve spring is connected to the upper end of the valve core of the one-way valve, and a valve seat of the one-way valve is arranged at the top end of the one-way valve body; and the one-way valve body is provided with the gas storage structure. The caliper air bleed screw can press gas in a pipeline and a caliper piston into a collecting room in the vent screw to a certain extent, then the gas is discharged into the atmosphere to prevent the gas in the system from lowering the performance of a brake system, and the safety performance of a car is improved.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a caliper deflation screw. Background technique [0002] When the car is running at high speed, a large amount of frictional heat is generated due to frequent braking, which increases the temperature of the braking system. If the brake fluid with a low boiling point and easy to evaporate is used, the evaporation of the brake fluid will cause The pipes of the local braking system are filled with steam, causing air resistance and causing brake failure. The current brake fluid has a certain degree of water absorption, and it will automatically absorb moisture in the air when it is exposed to the air. The boiling point of water is 100°C, and the high temperature of disc brakes can reach 400°C during continuous braking. There will be air bubbles in the road, resulting in air resistance. Contents of the invention [0003] The technical problem to be solved by the present invention is to o...
