Abstract

The invention provides an integrated electric servo brake system for a vehicle. The system comprises a brake operating mechanism, a brake main cylinder assembly, a wheel brake assembly and a hydraulicloop. The brake main cylinder assembly comprises a liquid storage tank; the brake operating mechanism is in transmission connection with the brake main cylinder assembly; the wheel brake assembly includes a brake wheel cylinder; the brake main cylinder assembly is communicated with the brake wheel cylinder; the hydraulic loop includes a supercharging module; the supercharging module comprises a supercharging cylinder body, a motor and a ball screw which is in rigid connection with the motor, wherein a hydraulic piston is arranged in the supercharging cylinder body and installed on the inner side of a ball screw cylinder body; the ball screw is also connected with the hydraulic piston, the motor drives the ball screw to move, and correspondingly the ball screw drives the hydraulic piston to move; one end of the supercharging module is communicated with the liquid storage tank, and the other end of the supercharging module is communicated with the brake wheel cylinder. The whole reliability of the system is improved, and working noise, installation volume and weight are reduced.

Description

technical field [0001] The invention relates to the field of new energy vehicle braking systems, in particular to a vehicle integrated electric servo braking system. Background technique [0002] In the current car market, the braking system of most cars has been powered by the engine-driven vacuum booster pump for 40 years. The potential for reducing costs and improving functions under this principle is already very small. The market potential of pure electric / hybrid vehicles in the future is huge. While continuing to use the existing vacuum booster / electronic vacuum booster structure, OEMs urgently need a new type of brake-by-wire system that can not only reduce cost, size, and energy consumption, but also seamlessly cooperate to achieve braking energy recovery, auxiliary Braking, active braking and other advanced functions. [0003] The brake-by-wire system was first proposed in the late 1980s, and has been recognized as the development trend of the future brake system....
