Abstract

A torque transfer mechanism includes an input member to receive from a propulsion source, an input torque about an axis of rotation and an output member coupled to the input member to transfer the input torque to a downstream driveline component. The torque transfer mechanism also includes at least one clock spring to restrict relative rotation between the input member and the output member. The torque transfer further includes a mass plate coupled to the output member and configured to rotate about the axis of rotation. The torque transfer mechanism further includes a plurality of pendulum masses movably coupled to the mass plate, wherein the clock spring is arranged to attenuate a first range of input torque vibration and a plurality of pendulum masses are arranged to attenuate a secondrange of input torque vibration.

Description

technical field [0001] The present invention relates to damping driveline disturbances while transmitting torque. Background technique [0002] Engine torque disturbances not absorbed by a driveline device, such as a torque converter, may pass directly to downstream portions of the driveline and vehicle structure through one or more torque couplings, such as clutches. Those torque disturbances can create unwanted jolts, back and forth, and / or vibrations that may be perceived by passengers. The use of torque coupling clutches may be limited to certain limited vehicle operating conditions in an attempt to minimize some of the undesired effects here. However, it may be difficult to identify acceptable conditions to use conventional powertrain controllers to activate torque coupling clutches to avoid these disturbances. Contents of the invention [0003] The torque transmitting mechanism includes an input member that receives an input torque about the axis of rotation from a...
