CLUTCH ARRANGEMENT FOR A HYBRID VEHICLE POWERTRAIN

A clutch arrangement for a hybrid vehicle powertrain, comprises: 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 () for comprising an inner race () connected to rotate with the input shaft () and an outer race (); a coupling hub () rotationally coupled with the output shaft (); and 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. A coupling sleeve unit () is selectively and axially moveable across the coupling hub (), synchronizer ring () and outer race () between three positions: a neutral position, a first position where the coupling sleeve unit couples in rotation said 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. Also presented is a powertrain comprising such clutch arrangement.
