Abstract: A two-speed transmission for a vehicle is provided including 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 sun gear, at least one ring gear meshingly engaged with the pinion, and a carrier. The carrier supports the 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 different combinations of the sun gear, the pinion, the ring gear, the input shaft, and the carrier with one another or a ground. Such elements may include combinations of clutches, brakes, and dog clutches.

Abstract: A transmission includes a housing, a first shaft rotatably supported relative to the housing, and a second shaft rotatably coupled to the first shaft. A switch-type clutch assembly is movable between an engaged state having a first clutch member coupled to a second clutch member and a disengaged state having the first clutch member separated from the second clutch member. The housing rotates with the first shaft when the switch-type clutch assembly is in the engaged state. A friction clutch is movable between an engaged state having a first friction plate coupled to a second friction plate and a disengaged state having the first frication plate separated from the second frication plate. The second shaft is fixed for rotation with the first shaft via the housing when the switch-type clutch assembly and the friction clutch assembly are both in the engaged state.

Abstract: A dual-clutch transmission assembly and method for controlling the same is provided where the torque generated by an engine is split between first and second shafts. Torque is supplied to the first shaft by a first clutch and torque is supplied to the second shaft by a second clutch. A first gearset is carried on the first shaft and a second gearset is carried on the second shaft. The first gearset includes a primary first gear and the second gearset includes a duplicate first gear. The first and second shafts receive torque from a 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.

Abstract: A clutch assembly that is less prone to overheating is disclosed. The clutch assembly includes 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.

Abstract: A torque split dual-clutch transmission assembly is disclosed that splits the torque generated by an engine between at least two sets of transfer gears that are selectively coupled to first and second layshafts or intermediate shafts. 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. Each set of transfer gears receives torque from either the transmission input shaft or the first and second layshafts in response to contemporaneous engagement of the first clutch and the second clutch, which can be used during vehicle launch to split the torque applied to the first and second clutches.

Abstract: A clutch assembly is disclosed having a clutch housing and a shaft. A clutch pack selectively couples rotation of the clutch housing and the shaft. The clutch pack includes a primary backing plate, a reaction plate, first and second friction plates disposed between the backing plate and the reaction plate, and a secondary backing plate disposed between the first and second friction plates. A first actuator selectively applies pressure to the reaction plate to move the reaction plate toward the primary backing plate. A second actuator controls movement of the secondary backing plate to switch the clutch pack between a low torque state and a high torque state. In the low torque state, the secondary backing plate cannot move longitudinally toward the primary backing plate beyond a locked position. In the high torque state, the secondary backing plate can move beyond the locked position.

The clutch pack includes a first apply plate, a second apply plate, a plurality of friction plates, and a plurality of reaction plates. The clutch assembly further includes a first actuator and a second actuator. The first actuator applies pressure to the first apply plate in a first direction to move the first apply plate toward the second apply plate. The second actuator applies pressure to the second apply plate in a second direction to move the second apply plate toward the first apply plate. The first direction is opposite the second direction such that the first and second actuators apply pressure to the clutch pack in opposing directions. This reduces localized temperature spikes in the clutch pack.

Abstract: A fuel pump assembly including a fuel pump and a variable drive mechanism is provided. The fuel pump has a pump input shaft rotatably coupled to an impeller. The variable drive mechanism has a drive input shaft that receives torque from the engine of a vehicle and a drive output shaft that is rotatably coupled to the pump input shaft. The variable drive mechanism further comprises a planetary gearset interconnecting the drive input shaft and the drive output shaft. The planetary gearset has a variable gear ratio that varies rotational speed of the drive output shaft and therefore the pump input shaft relative to the rotational speed of the drive input shaft. Accordingly, the rotational speed of the pump input shaft and thus the volume flowrate of the fuel pump can be adjusted for any given engine speed to minimize pump related losses.
