Abstract

The invention provides an electric power-assisted braking system which comprises a pedal simulator device, a power-assisted transmission mechanism, a power-assisted return device and a supporting shell, and the pedal simulator device is installed at one end of the supporting shell and extends into the supporting shell; the power-assisted transmission mechanism is installed at the other end of thesupporting shell and extends into the supporting shell. A pedal push rod of the pedal simulator device is connected in series with a power-assisted push rod of the power-assisted transmission mechanism, so that decoupling during electric power assistance and coupling without power assistance are realized; the power-assisted return device is installed on the power-assisted transmission mechanism and used for driving a power-assisted push rod of the power-assisted transmission mechanism to return. According to the invention, the transmission mechanism is arranged in the mode that a lead screw and a gear are combined, the pedal simulator device with a large spring and a small spring connected in parallel is matched, the transmission efficiency of the transmission mechanism can be improved, and the brake response speed is increased; and in the pedal treading process of a user, the foot feeling is smoother and the pedal feeling is adjustable.

Description

technical field [0001] The invention relates to the field of braking systems, in particular to an electric power-assisted braking system. Background technique [0002] In the prior art, with the vigorous development and application of new energy vehicles represented by electric vehicles and hybrid vehicles, the cruising range of vehicles has always been a major concern of the majority of users. The braking system has always been a key research object of automobiles. The current development trend of intelligence and electrification has put forward higher requirements and challenges for the braking system to be able to actively build pressure and realize the function of braking energy recovery. In addition to satisfying the adjustable brake pedal and active braking functions of intelligent driving, the braking system also needs to work with the regenerative braking system to ensure the efficiency of braking energy recovery and maintain a good brake pedal feel. [0003] The el...
