車両用電磁クラッチ
Document Type and Number:
Japanese Patent JP7238832
Kind Code:
B2
Abstract:
A vehicle electromagnetic clutch (24) includes: an electromagnetic coil (52); an armature (54); a first cam member (58) and a second cam member (60) that are configured to be rotated relative to each other about a rotation axis (C); and a damping plate (74) disposed over a back surface (54c) of the armature (54) and configured to damp vibration of the armature (54), the back surface (54c) being an opposite surface of the armature (54) from an opposing surface (54b) facing the electromagnetic coil (52), and the damping plate (74) being disposed without being restrained in a rotational direction. When a current is applied to the electromagnetic coil (52), the electromagnetic coil (52) attracts the armature (54) and a friction force is applied to the armature (54), and the first cam member (58) and the second cam member (60) are rotated relative to each other by torque generated by the friction force to move the second cam member (60) in the direction of the rotation axis.
