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 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.

Abstract: A baffle for disposition in a sump having a fluid containing cavity is disclosed. A first portion of the baffle has an outside edge abutting a side wall of the sump and an inner edge defining an opening. A second portion of the baffle extends downwardly from the inner edge to a lower edge abutting a bottom wall of the sump. At least one jalousie divider is disposed along the second portion of the baffle to regulate fluid flow through the baffle based on fluid temperature. A controller is coupled to the jalousie divider to selectively drive the jalousie divider to a closed position that prevents fluid flow through the baffle when the fluid temperature is below a temperature threshold and an open position that permits fluid flow through the second portion of the baffle when the fluid temperature is above the temperature threshold.

Abstract: A power transmitting device for a vehicle having a power plant and a drivetrain is provided. The power transmitting device includes an output shaft that provides torque to the drivetrain and a manual transmission selectable between a first gear set having a first gear ratio and a second gear set having a second gear ratio that transmits power to the output shaft at different rotational speeds. The power transmitting device also includes a hydraulic torque converter that multiplies torque. Torque is multiplied through the torque converter and is transmitted to the output shaft from the torque converter when the first gear set is selected and is not multiplied through the torque converter when the second gear set is selected.

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.
