Torque transmission device with enhanced ability to absorb change in rotation between torque input and output member

Abstract

A torque transmission device which may be used to transmit torque, as inputted from an automotive engine through a belt, to an accessory such as an alternator and is designed to have enhanced ability to absorb a change in rotation of a torque input member relative to an torque output member. The torque transmission device includes a slider sensitive to a given change in rotation of the input member relative to the output member to experience sliding motion and an elastic absorber which suppresses the sliding motion elastically to absorb the change in rotation of the input member. The elastic absorber is mechanically retained by the output member and inertially independent of the input member, so that the moment of inertia of the input member will be small, thus resulting in enhanced ability to absorb the change in rotation of the input member.
