Design of Double-Disc Friction and Electromagnetic Hybrid Brake System of Passenger Car

The electromagnetic brake has already been acknowledged by users as one kind of contactless brake. In this paper, the basic principle and application of electromagnetic braking technology were briefly introduced first. Then the structure of the innovative hybrid brake with double disc was put forward. It employed an electromagnetic braking to reduce brake pad wear and braking system thermal recession. Based on the design requirements, the friction brake and the electromagnetic brake were designed respectively. Finally, in order to verify that whether the designed hybrid brake meets the design requirements, a bench test was carried out. The electromagnetic braking torque characteristic was tested. The results showed that the electromagnetic braking torque could approach 198N·m.Thus the design method is feasible..
