Abstract

A pulley which can be driven by the output element of the engine in a motor vehicle to transmit torque to one or more endless belts or chains has a rotary input member, a rotary output member and a damper which yieldably opposes rotation of the input and output members relative to each other about a common axis and is at least partially confined in an annular chamber defined by at least one of the input and output members. The chamber can further receive a friction bearing which operates between the input and output members, as well as a vibration absorbing device. Such device can have a mass which is adjacent a flange of one of the input and output members and one or more energy storing elements acting in the circumferential direction of the pulley.
