Abstract
A decoupler for damping torque transmission irregularities between a vehicle drive shaft and a belt pulley for driving vehicle auxiliary components. The decoupler includes first and second ramp rings for transmitting torque delivered by the drive shaft to the belt pulley. A spring arrangement provides for axial engagement of the ramp rings. The ramp rings have respective sloped push and pull ramps directed toward the adjacent ramp ring so that in a coasting mode of the vehicle the ramp rings rotate relative to each other and in a vehicle drive mode the ramp rings are drawn toward one another. The decoupler includes a pulley damper for damping torque transmission irregularities to reduce noise emission.
