Abstract: Transmissions and clutch assemblies for transmissions are disclosed herein. A transmission includes an input shaft, an output shaft, and a clutch assembly. The input shaft is configured to receive rotational power. The output shaft is configured to transmit rotational power to a load. The clutch assembly is coupled between the input shaft and the output shaft to selectively transmit rotational power therebetween in use of the transmission. The clutch assembly includes a housing, a piston, and a disc spring. The piston is movable relative to the housing and cooperates with the housing to at least partially define a first cavity that is configured to receive hydraulic fluid such that a first centrifugal pressure force is created in use of the clutch assembly. The disc spring is movable relative to the housing.

Abstract: Vehicles, powertrains for vehicles, and methods of mounting powertrains to chassis of vehicles are disclosed herein. A vehicle includes a chassis, a plurality of wheels, and a powertrain. The chassis extends along a longitudinal axis from a first end to a second end arranged opposite the first end. The plurality of wheels are coupled to the chassis between the first end and the second end and configured for rotation about a rotational axis. The powertrain is mounted to the chassis transverse to the longitudinal axis between the first end and the second end. The powertrain is configured to drive rotation of the plurality of wheels about the rotational axis in use of the vehicle.

Abstract: A transmission system efficiently performs efficiently and also provides the ability to perform full-power shifts. For example, a secondary clutch actuator, independent of fluid actuation, may eliminate the need for a pump to continuously provide high pressure during regular vehicle operation such that high pressures are only required during a shift event. This eliminates the need for energy at the pump to maintain application of the clutch, thereby allowing such energy to be used of other systems in the EV or to facilitate increased vehicle range.
