Abstract
A torque transfer mechanism includes an input member to receive an input torque from a propulsion source, and an output member coupled to the input member to transfer the input torque to a driveline component. A multi-component damping mechanism is disposed between the input member and the output member which includes a first spring element cooperating with a second spring element to couple the input member to the output member. The first spring element defines a greater stiffness and shorter deflection relative to the second spring element.
Claims20
A torque transfer mechanism comprising:
- an input member to receive an input torque from a propulsion source;
- an output member coupled to the input member to transfer the input torque to a driveline component;
- and
- a multi-component damping mechanism disposed between the input member and the output member including a first spring element cooperating with a second spring element to couple the input member to the output member, wherein the first spring element defines a greater stiffness and shorter deflection relative to the second spring element.
A torque transfer mechanism comprising:
- a rotatable input member to receive an input torque from a propulsion source;
- a first member coupled to the input member to transfer torque;
- at least one elastic second member arranged to receive transferred torque from the first member;
- an output member torsionally coupled to the elastic second member, the output member configured to transfer an output torque to a downstream element in a vehicle powertrain, wherein actuation of the first member changes a resistive torque response of the elastic second member.
A torque transfer mechanism comprising:
- an input member to receive an input torque from a propulsion source;
- an output member coupled to the input member to transfer the input torque to a driveline component;
- and
- a multi-component damping mechanism arranged to restrict relative rotation between the input member and the output member and provide a first spring rate during a first portion of relative rotation and a second spring rate during a second portion of relative rotation.
