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.

    本发明提供了一种电动助力制动系统,其包括踏板模拟器装置、助力传动机构、助力回位装置和支撑壳体,踏板模拟器装置安装在支撑壳体的一端部,并向支撑壳体内延伸;助力传动机构安装在支撑壳体的另一端部,并向支撑壳体内延伸;踏板模拟器装置的踏板推杆与助力传动机构的助力推杆相互串联在一起,实现电动助力时的解耦及无助力时的耦合;助力回位装置安装在助力传动机构上,用于带动助力传动机构的助力推杆回位。本发明通过采用丝杠和齿轮结合的方式设置传动机构,配合大弹簧和小弹簧并联的踏板模拟器装置,可以提高传动结构的传动效率,加快制动响应速度,用户在踩踏板过程中,脚感更加的平滑,且踏板感可调。
