Title: Electromagnetic clutch and driving force transmission device using the same
Inventor: SAITO YASUNARI
IPC: F16D27/115
Filed: 2000-12-12
Abstract: PROBLEM TO BE SOLVED: To suppress fluctuation of a clutch characteristic of an electromagnetic clutch and to prevent generation of abnormal sound by reducing the fluctuation width of repeated fluctuation of energizing current to an electromagnetic coil of the electromagnetic clutch when performing a duty control for the energizing current. SOLUTION: A copper ring 18 is disposed in a state of the coated copper ring 18 (coating layers 16a and 18a) in the vicinity of a circulation magnetic path X of the electromagnetic clutch. By disposing the copper ring 18, counter electromotive voltage caused by fluctuation of the number of magnetic fluxes is generated and reverse direction current in a direction reverse to current fluctuation of the electromagnetic coil is generated. The reverse direction current acts so as to offset fluctuation of energizing current, to reduce the fluctuation width of repeated fluctuation of energizing current, to maintain engaging force of the electromagnetic clutch in a small fluctuation width state and to reduce generation of abnormal sound caused by repeated fluctuation of the engaging force. The coating layers 16a and 18a prevent electric corrosion and oxidation of the copper ring 18a.
