The structure and control method on the electromagnetic brake system with electromagnetic clutch function

摘要

Electromagnetic brake system with electromagnetic clutch includes frictional function and electromagnetic brake device brake, friction brakes and electromagnetic brake are mounted coaxially on the rear axle, and the friction brake disc friction braking and electromagnetic brake device are provided with matching chuck and electromagnetic clutch disc clutch engagement. When the car brakes, the controller will control the output current to the electromagnetic clutch sucker, sucker electromagnetic clutch after clutch engagement will energize the disc against the spring force of pulling, the rolling bearing moves toward the direction of the electromagnetic clutch sucker and eventually pull together. After calculating the torque of the electromagnetic brake system with electromagnetic clutch function, the simulation and experiment are carried out. As the result shows that the electromagnetic brake system can recover the energy of the car during the brake process, and let the car brake effectively.
