Abstract
A selectable torque transfer system includes an input member to receive an input torque, and an output member that is selectively coupled to the input member. The selectable torque transfer system also includes an engaging member disposed between the input member and the output member and a biasing element configured to urge the engaging member towards a first position. The selectable torque transfer system further includes an electrically-powered solenoid configured to actuate the engaging member to a second position thereby enabling torque transfer from the input member to the output member.
Claims20
A selectable torque transfer system comprising:
- an input member to receive an input torque;
- an output member selectively coupled to the input member;
- an engaging member disposed between the input member and the output member;
- a biasing element configured to urge the engaging member towards a first position;
- and
- an electrically-powered solenoid configured to actuate the engaging member to a second position thereby enabling torque transfer from the input member to the output member.
A propulsion system comprising:
- a transmission having a plurality of gear elements to convert a first input torque into a second output torque;
- at least one selectable torque transfer element disposed within the transmission to selectively decouple a torque flow from the first input torque to the second output torque;
- an electrically-powered solenoid configured to actuate the at least one selectable torque transfer element to engage at least one gear element when energized;
- and
- at least one biasing element to bias the selectable torque element to decouple torque flow when the solenoid is de-energized.
A propulsion system comprising:
- a transmission having a plurality of gear elements to convert a first input torque into a second output torque;
- an input member to receive an input torque from a propulsion source;
- an engaging member configured to selectably actuate to control a transfer of the input torque to an output member;
- a biasing element configured to urge the engaging member towards one of a first position and a second position;
- and
- an electrically-powered solenoid configured to actuate the engaging member to the other of the first position and the second position enabling torque transfer from the input member to the output member.
