The provided are a brake-by-wire (BBW) electronic control actuator unit and a use thereof. The BBW electronic control actuator unit includes a machine body, as well as a permanent magnet brushless direct-current motor (PMBDCM) and speed-reducing torque-increasing gear sets integrated in the machine body, where the PMBDCM includes a stator assembly and a rotor assembly; the rotor assembly is connected to one end of a motor shaft; the other end of the motor shaft is connected to an input end of each of the speed-reducing torque-increasing gear sets; an output end of the speed-reducing torque-increasing gear set is connected to an output shaft; and the output shaft extends out of the machine body. According to the BBW electronic control actuator unit and the use thereof, by assembling the PMBDCM and the speed-reducing torque-increasing gear set, there are advantages of a high mounting accuracy, and a compact structure.

Brake-by-wire (BBW) electronic control actuator unit and use thereof

An electro-hydraulic braking system includes a main casing. A hydraulic unit brake master cylinder is provided in the main casing. An outer end of a piston rod of the brake master cylinder is connected to an output top rod. Another end of the output top rod is provided with an input rod. The input rod is slidably connected in the main casing along only a length direction of the input rod, and another end of the input rod is provided with a push rod that is configured to transmit a brake pedal force. The main casing is further provided therein with a reset member configured to push the push rod away from the brake master cylinder to reset and a displacement sensor configured to sense a displacement of the push rod. The input rod and the output top rod include a spacing state and an abutment state.
