Abstract
A clutch assembly comprises a first clutch member configured to selectively couple a first torque input and a second torque input for torque transmission therebetween. The clutch assembly includes a second clutch member configured to selectively couple the second torque input and a third torque input for torque transmission therebetween. In one embodiment, the first clutch member is nested radially inside the first torque input, the second torque input is nested radially inside the first clutch member, the second clutch member is nested radially within the second torque input, and the third torque input is nested radially within the second clutch member.
Claims18
A clutch assembly comprising:
- a first clutch member configured to selectively couple a first torque input and a second torque input for torque transmission therebetween;
- a second clutch member configured to selectively couple the second torque input and a third torque input for torque transmission therebetween;
- and
- wherein the first clutch member is nested radially inside the first torque input, the second torque input is nested radially inside the first clutch member, the second clutch member is nested radially within the second torque input, and the third torque input is nested radially within the second clutch member.
A clutch assembly comprising:
- a first clutch member movable between an engaged position and a disengaged position to selectively couple a first torque input and a second torque input for torque transmission therebetween;
- and
- a second clutch member movable between an engaged position and a disengaged position to selectively couple the second torque input and a third torque input for torque transmission therebetween,
- wherein:
- in a first mode of operation, the first clutch member and the second clutch member are both in the disengaged position such that the first torque input is decoupled from the second torque input and the second torque input is decoupled from the third torque input;
- in a second mode of operation, the first clutch member is in the engaged position such that the first torque input is coupled to the second torque input and the second clutch member is in the disengaged position such that the second torque input is decoupled from the third torque input;
- in a third mode of operation, the first clutch member is in the disengaged position such that the first torque input is decoupled from the second torque input and the second clutch member is in the engaged position such that the second torque input is coupled to the third torque input;
- and
- in a fourth mode of operation, the first clutch member and the second clutch member are both in the engaged position such that the first torque input is coupled to the second torque input and the second torque input is coupled to the third torque input.
A method of operating a clutch assembly having a first clutch member and a second clutch member, the method comprising:
- moving the first clutch member between a first position where a first torque input is coupled to a second torque input to transmit torque therebetween and a second position where the first torque input is decoupled from the second torque input such that there is no torque transmission therebetween;
- and
- moving the second clutch member between a first position where the second torque input is coupled to a third torque input to transmit torque therebetween and a second position where the second torque input is decoupled from the third torque input such that there is no torque transmission therebetween,
- wherein the first clutch member is disposed radially between the first torque input and the second torque input, and the second clutch member is disposed radially inward of the first clutch member and radially between the second torque input and the third torque input.
