Abstract

A vehicle powertrain includes a power source, a clutch arrangement and a housing, the clutch arrangement arranged between the power source and a transmission. The clutch arrangement includes: a first clutch arranged to couple the power source to a first input shaft of the transmission and a second clutch arranged to couple the power source to a second input shaft of the transmission; and a torque transmission member having an extension in a radial direction and adapted to transmit torque from the power source to one of the first or second input shafts. The torque transmission member includes clutch lamellae carriers for the first and second clutches. The torque transmission member is journaled at a radially inner portion against the housing via one or more first bearings, and an output rotor shaft of the power source is journaled against the housing via one or more second bearings.
