Abstract
A clutch arrangement for a hybrid vehicle powertrain including an input shaft to be connected to a crankshaft of an internal combustion engine, an output shaft for connection to a transmission, a one-way clutch comprising an inner race connected to rotate with the input shaft and an outer race, a coupling hub rotationally coupled with the output shaft, a synchronizer ring arranged between the coupling hub and the one-way clutch, the synchronizer ring cooperating with the outer race of the one-way clutch, and a coupling sleeve unit that is selectively and axially moveable across the coupling hub. The synchronizer ring and the outer race include three positions, a neutral position, a first position, and a second position.

A clutch arrangement for a hybrid vehicle powertrain, comprising:
- an input shaft to be connected to a crankshaft of an internal combustion engine;
- an output shaft for connection to a transmission;
- a one-way clutch comprising an inner race connected to rotate with the input shaft and an outer race;
- a coupling hub rotationally coupled with the output shaft;
- a synchronizer ring arranged between the coupling hub and the one-way clutch, the synchronizer ring cooperating with the outer race of the one-way clutch;
- and
- a coupling sleeve unit that is selectively and axially moveable across the coupling hub,
- wherein the synchronizer ring and the outer race include three positions:
- a neutral position,
- a first position where the coupling sleeve unit couples in rotation the coupling hub, the synchronizer ring, and the outer race, and
- a second position where the coupling sleeve unit couples in rotation the coupling hub, the synchronizer ring, the outer race, and the inner race.
