Abstract: An architecture for coupling the output of a prime mover to a rotationally driven device. The architecture includes a selectable switching device, a terminal output member and a torque transfer device having an intermediate output member. The selectable switching device is coupled to the output of the prime mover and is selectively and alternately coupled between first and second states; in the first state with the torque transfer device, whereby the torque transfer device is rotatably driven by the prime mover and the terminal output member is rotatably driven by the intermediate output member of the torque transfer device; and in the second state with the terminal output member, whereby the terminal output member is rotatably driven by the prime mover and the torque transfer device is rotatably disconnected from the prime mover and is not rotatably driven.

Abstract: Systems and methods for an electric powertrain. The method, in one example, includes responsive to receiving a shift command, engaging a second friction clutch while disengaging a first friction clutch to transition from a first operating gear ratio to a second operating gear ratio. The method, further includes during the gear ratio transition, operating a traction motor under a peak condition, the peak condition denotes a condition where the motor speed is greater than a maximum continuous torque curve of the motor.

Abstract: A dual clutch power shift transmission is provided. The transmission includes an input shaft, a main shaft rotationally coupled to the input shaft, and an output shaft coupled to the input shaft. An odd shaft and an even shaft carry a plurality of gears. The gears define a predetermined gear ratio between the input shaft and output shaft. The odd shaft and even shaft are coupled to the input shaft via an odd clutch, and even clutch, and a master clutch. A forward clutch and a reverse clutch are interposed between the master clutch, odd clutch, and even clutch. The forward and reverse clutch are alternatively coupled to the input shaft. An intermediate shaft assembly, rotationally coupled to the gears, is interposed between the odd shaft and even shaft. An auxiliary shaft is interposed between the odd shaft and output shaft and carries range gears defining a predetermined gear ratio.

Abstract: A transmission includes a primary gear including primary teeth, each having a primary surface; a secondary gear including secondary teeth; an intermediate gear including intermediate teeth, each comprising a primary intermediate part having a primary intermediate surface and a secondary intermediate part having a secondary intermediate surface, where the primary intermediate part is axially offset from the secondary intermediate part. The intermediate gear is axially displaceable to an engaged position. The primary surface contacts the primary intermediate surface in a contact region and the secondary intermediate surface contacts one of the secondary teeth. In the engaged position, one primary tooth and one intermediate tooth form an overlap, radially inside the contact region, for preventing the intermediate gear from being displaced from the engaged position to a disengaged position.

A plurality of shiftable first gear wheel sets connect the input shaft and the layshaft and are each associated with at least one gear stage. A machine gear which is connected or can be connected to one of the shafts and into which the drive torque of an electric machine can be introduced. The first gear wheel sets form a first part-gear mechanism, wherein at least one second shiftable gear wheel set connects the layshaft and the output shaft and forms a second part-gear mechanism. The at least one second gear wheel set is associated with at least one gear stage. The housing defines a cooling fluid sump.

Abstract: A powershift transmission has a split group with a plurality of powershift stages and an input shaft that can be rotatably driven by a drive shaft of a motorized drive. The input shaft transmits in a stepped-up manner to an output shaft of the split group a rotational movement corresponding to a selected powershiftable stage transmission. A synchromesh transmission group has at least four gear stages and can be rotatably driven by the output shaft of the split group via an intermediate group located therebetween, and via the output shaft of the synchromesh transmission group an axle transmission of the motor vehicle can be rotatably driven. The intermediate group has first and second switching elements each having an output shaft that can be coupled by means of a switchable clutch to an idler. First and second output gears are arranged on the output shaft of the synchromesh transmission group.
