Abstract: An axle assembly for a vehicle includes a frame, a motor, and a pair of gear reduction subassemblies. The frame extends between a first distal end and a second distal end. The second distal end opposes the first distal end. The motor is secured to the frame between the first distal end and the second distal end. The pair of gear reduction subassemblies are rotatably coupled to the first distal end and the second distal end and configured to drive rotation from the motor to a pair of wheels. Each gear reduction subassembly includes a plurality of gears defining a plurality of gear ratios.

Abstract: A two-speed transmission for an electric vehicle includes a planetary gear set selectively coupling an input shaft and an output shaft. The planetary gear set is configured to provide two forward gear ratios and neutral. The planetary gear set includes at least one sun gear, at least one pinion in meshing engagement with the at least one sun gear, at least one ring gear meshingly engaged with the at least one pinion, and a carrier. The carrier supports the at least one pinion and is connected to the output shaft such that rotation of the carrier drives the output shaft. The two-speed transmission also includes one or more elements that rotatably couple the at least sun gear, the at least one pinion, the at least one ring gear, the input shaft, and the carrier with one another and/or a ground. Examples of such elements include clutches, brakes, and mechanical diodes.

Abstract: A method for reducing overheating in a clutch assembly having a clutch housing, a shaft, and a clutch pack. The clutch pack includes a backing plate, an applied plate, a plurality of friction plates, and a plurality of reaction plates. A primary actuator applies pressure to the applied plate to longitudinally compress the entire clutch pack and couple rotation of the clutch housing and the shaft. A secondary actuator applies pressure to at least one plate in the plurality of friction plates and the plurality of reaction plates to longitudinally move the at least one plates independently of the applied plate. This relieves some of the torque transmitted across the clutch pack adjacent the applied plate and reduces localized temperature spikes in the clutch pack adjacent to the applied plate.

Such elements may include combinations of clutches, brakes, and dog clutches.

Abstract: An opposed piston engine may include a first housing, first and second pistons, and first, second, and third fuel injector nozzles. The first housing may define a first passage extending along a first longitudinal axis. The first and second pistons may be slidably disposed within the first passage. The first, second, and third fuel injector nozzles may be in fluid communication with the first passage. At least one of the first, second, and third fuel injector nozzles may be angularly offset from another one of the first, second, and third fuel injector nozzles by an oblique angle about the first longitudinal axis.

Abstract: A torque converter for coupling an engine to a manual transmission and a method of controlling the same are provided. The torque converter includes a housing rotating with the engine, a cover abutting the housing, a stator, a pump circulating fluid within the torque converter, and a turbine driven by the circulating fluid. An integrated disconnect clutch controls pump speed and a torsional damper attenuates vibrations transmitted through the housing. A first output shaft is coupled with the turbine and drives a first forward gear of the manual transmission while permitting slip. A second output shaft is coupled with the torsional damper, the integrated disconnect clutch, and the pump and drives at least one other forward gear of the manual transmission without slip. An output connection member rotatably couples the pump with the torsional damper, the integrated disconnect clutch, and the second output shaft.

Abstract: A clutch assembly is provided that includes a first shaft, a second shaft, a housing, a two-way over-running clutch, and a friction clutch assembly. The two-way over-running clutch includes an inner race and an outer race. At least one torque transmitting member is disposed between the inner race and the outer race that selectively transfers torque from the inner race to the outer race. The inner race defines at least one cam that receives the torque transmitting member. An inner race actuator selectively controls lock-up of the two-way over-running clutch by moving the inner race relative to the first shaft and the outer race between a concentric position and at least one eccentric position.

Abstract: A dual-clutch transmission assembly is disclosed that splits the torque generated by an engine between first and second layshafts. A first input hub is connected to the first layshaft by a first clutch and a second input hub is connected to the second layshaft by a second clutch. A first gearset is carried on the first layshaft and a second gearset is carried on the second layshaft. The first gearset includes a primary first gear and the second gearset includes a duplicate first gear. The first and second layshafts receive torque from the transmission input shaft in response to contemporaneous engagement of the primary first gear, the duplicate first gear, and the first and second clutches, which can be used during vehicle launch to split the torque applied to the first and second clutches.
