Problems solved by technology

The traditional brake master cylinder needs to process a Φ0.7mm compensation hole on the cylinder body. By setting the compensation hole, the filling and discharge of the brake oil inside the cylinder body can be accelerated, but the processing technology of this small hole is extremely difficult. Big, difficult to control the quality

Abstract

The invention discloses a brake master cylinder assembly with double one-way valves. The invention relates to the technical field of automobile parts. The assembly comprises a brake master cylinder, apiston I and a piston II, a cylindrical cavity with a leftward opening is formed in the brake master cylinder; an L-shaped front oil inlet is formed in the upper portion, close to the right end, of the outer wall of the brake master cylinder. A rear oil inlet is formed in the upper portion, close to the left side, of the outer wall of the brake master cylinder. The outer wall of the brake mastercylinder is provided with a front oil outlet on the left side of the front oil inlet; a rear oil outlet is formed in the right side of the rear oil inlet in the outer wall of the brake master cylinder; the front oil inlet, the rear oil inlet, the front oil outlet and the rear oil outlet are all communicated with the cavity, a rhombic installation lug is arranged on the left side of the outer wallof the brake master cylinder, a hole check ring is installed on the left side of the cavity of the brake master cylinder, and the first piston and the second piston are arranged in cavities in the inner side of the hole check ring in a right-to-left mode respectively. According to the brake master cylinder assembly with the double one-way valves, the situation that a compensation hole with the diameter phi of 0.7 mm needs to be machined in a cylinder body of a traditional brake master cylinder is avoided.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a brake master cylinder assembly with double check valves. Background technique [0002] Brake master cylinder, also known as hydraulic brake master cylinder, is the power source of the service brake system. The braking force comes from the pedal force applied by the driver on the brake pedal and the vacuum (vacuum boost) of the engine intake manifold, where the vacuum is the main power source of the master cylinder. The main function of the master cylinder is to convert the mechanical force exerted by the driver on the brake pedal and the force of the vacuum booster into brake oil pressure, and send the brake fluid with a certain pressure to each wheel through the brake pipeline. The brake wheel cylinder (slave cylinder) is converted into wheel braking force by the wheel brake. The traditional brake master cylinder needs to process a Φ0.7mm compensation hole on the cylinder...
