Integrated master cylinder for part-time braking systems

Abstract

The invention discloses an integrated type main cylinder suitable for a time division brake system. The problems that in the prior art, a pedal sensory simulator cannot be adjusted, the occupied space is large, a separate pressure source needs to be additionally arranged, and the energy utilization ratio is low are solved. The integrated type main cylinder comprises a main cylinder body, a first main cylinder, a first main cylinder return spring, a second main cylinder piston, a second main cylinder return spring, a pushing rod piston, a brake pedal, a spring assembly and a sleeve piston; the first main cylinder return spring, the first main cylinder piston, the second main cylinder return spring, the second main cylinder piston, the sleeve piton, the spring assembly and the pushing rod piston are sequentially mounted in the main cylinder body from left to right, and the sleeve piston, the spring assembly and the pushing rod piston are mounted in a right cylinder body of the main cylinder body; the spring assembly is mounted between the sleeve piston and the pushing rod piston and mounted on the periphery of the pushing rod portion, between the sleeve piston and the pushing rod piston, of the pushing rod piston in a sleeving mode; and one end of the spring assembly is fixedly connected with the right side face of the sleeve piston, and the brake pedal is hinged to the right end of the pushing rod piston.

Description

technical field [0001] The invention relates to a device belonging to an automobile brake system, more precisely, the invention relates to an integrated master cylinder suitable for a time-sharing brake system. Background technique [0002] In the structure of modern automobiles, the braking system is an indispensable system of the vehicle, and it is a necessary structure to ensure the safety of the vehicle. The brake-by-wire system is divided into an electro-hydraulic brake system and an electro-mechanical brake system. Because the electro-mechanical brake system cannot be used when the system is powered off, there are great hidden dangers, so the current brake-by-wire systems are mostly electro-hydraulic hybrid. Controlled electro-hydraulic braking system. [0003] According to the control mode of the four wheel cylinders, the electronic hydraulic braking system can be divided into full-time braking type and time-sharing braking type. The full-time braking electronic hyd...
