  • Hybrid brake-by-wire system using a motor-magnetostrictive actuator combination
    Patent number: 10940845
    Abstract: The present invention discloses a motor-magnetostrictive actuator hybrid brake-by-wire system. The system includes a motor, a transmission mechanism, a magnetostrictive-driving piston mechanism and a floating-caliper disc mechanism. The transmission mechanism includes a planetary gear set and a screw set, and is driven by the motor. The linear motion of the sleeve is achieved by the planetary gear set and screw set. The sleeve pushes forward the piston head of the magnetostrictive-driving piston mechanism and the piston head pushes forward the brake pad back plate of the floating-caliper disc mechanism to clamp the brake disc, which accomplishes braking.
