Abstract

A clutch and a compressor including the same, and may include a hub fastened to a rotary shaft of a compressor and rotatable with the rotary shaft in a state where its position has been fixed, a disk fastened to the hub and rotatable with the hub, a pulley rotated by receiving power from a driving source of the compressor, an elastic member fastening the hub and the disk, fastening the hub and the disk so that the disk approaches or is away from the pulley based on the hub, a field coil assembly magnetized when power is applied to contact or space the disk and the pulley, an attenuation member interposed between the elastic member and the disk, thereby reducing the noise and vibration due to the contact and spacing between the disk and the pulley by the elastic member and the attenuation member.

Dependent claims

A clutch, comprising:

a hub fastened to a rotary shaft of a compressor and rotatable with the rotary shaft in a state where its position has been fixed;
a disk fastened to the hub and rotatable with the hub;
a pulley rotated by receiving power from a driving source of the compressor;
an elastic member fastening the hub and the disk, and fastening the hub and the disk so that the disk approaches or is away from the pulley based on the hub;
a field coil assembly magnetized when power is applied to contact or space the disk and the pulley;
and
an attenuation member interposed between the elastic member and the disk,
wherein the attenuation member comprises a first attenuation member contacting the disk and the elastic member during a contact period and a spacing period between the disk and the pulley, and a second attenuation member contacting the disk and the elastic member during a spacing period between the disk and the pulley, and spaced apart from one of the disk and the elastic member during a contact period between the disk and the pulley, and
wherein the second attenuation member spaces a contact surface between the elastic member and the disk during the spacing period between the disk and the pulley from a position such as a contact surface between the elastic member and the hub to the pulley side.
