A bi-directional drive assembly for a work vehicle has a reaction member fixed with respect to or a part of a drive housing. A driveshaft is rotatable about a drive axis relative to the reaction member in a first rotation direction and alternatively in a second rotation direction. A planetary set is coupled to the drive shaft and configured to rotate an output hub in the first or second rotation direction. A clutch assembly is coupled to the reaction member and includes a first clutch and a second clutch. The first clutch is configured to interface the planetary set with the reaction member to effect a first rotation speed of the output hub in the first rotation direction and alternatively the second rotation direction. The second clutch is configured to interface the planetary set with the reaction member to effect a second rotation speed of the output hub in the first rotation direction and alternatively the second rotation direction. An actuator arrangement is configured to effect movement of the first clutch and the second clutch along the drive axis to selectively engage the planetary set.

A power train for an electric vehicle may include an input shaft to which a motor is fixedly connected; an output shaft mounted in parallel to the input shaft; a first driving gear and a first driven gear mounted on the input shaft and the output shaft, respectively, to be gear-engaged with each other; a second driving gear and a second driven gear mounted on the input shaft and the output shaft, respectively, to be gear-engaged with each other; a one-way clutch mounted in a first path where power is transmitted from the input shaft to the output shaft through the first driving gear and the first driven gear; a restraining mechanism mounted to selectively restrain the one-way clutch from freely rotating; and a friction clutch mounted to regulate a second path where power is transmitted from the input shaft to the output shaft through the second driving gear and the second driven gear.

The present invention is a variable ratio shower mixing valve actuator. The system provides distinct advantages over existing shower valve actuators. The primary advantage is that the system allows a user to adjust the magnitude of the effect that a given actuation lever input will have on the output flow.

The first range clutching assembly is selectively drivingly engaged with the second clutching assembly and the second range clutching assembly.

The present disclosure provides a power-drive system for a vehicle and a vehicle. The power-drive system comprises: an engine; a plurality of input shafts; a plurality of output shafts, the plurality of output shafts linking with a differential of the vehicle; a first clutch device, arranged between the engine and the plurality of input shafts, so that the engine selectively engages with at least one of the plurality of input shafts; a first motor generator, configured to link with the differential of the vehicle; and a second motor generator, wherein the second motor generator and the engine are located on an input side of the first clutch device, the plurality of input shafts is located on an output side of the first clutch device, and the second motor generator is configured to carry out stationary power generation using at least part of power of the engine when the vehicle is parked.

A dual clutch transmission arrangement (4) includes a first clutch (K1) and a second clutch (K2) for connecting a drive unit (2) to a first sub-transmission and to a second sub-transmission. The first clutch (K1) is connected to both transmission input shafts. A motor vehicle with the dual clutch transmission arrangement (4) is also provided.

A transmission includes an input shaft coupled to a prime mover, a countershaft, main shaft, and an output shaft, with gears between the countershaft and the main shaft. The shift actuator is mounted on an exterior wall of a housing including the countershaft and the main shaft. A shift control circuit operates a shift actuator using a first opposing pulse command and a first actuating pulse command, and releases pressure with shift actuating and opposing volumes of the shift actuator upon determining a shift completion event.
