摘要： A dual-clutch transmission for use in a vehicle has a housing, a clutch pack drum adapted to rotate inside the housing, a central clutch gear connected to the clutch pack drum, a first clutch pack, a first clutch hub, a first pressure plate disposed on the first side of the central clutch gear, and a first shaft connected to the first clutch hub. The first shaft drives at least one first transmission gear when the first pressure plate squeezes the first clutch pack. The dual-clutch transmission further includes a second clutch pack, a second clutch hub, a second pressure plate disposed on the second side of the central clutch gear, and a second shaft connected to the second clutch hub. The second shaft drives at least one second transmission gear when the second pressure plate squeezes the second clutch pack. A vehicle having a dual-clutch transmission is also encompassed.

摘要： Methods and systems for a vehicle transmission are provided. A transmission system includes, in one example, an intermediate shaft rotationally coupled to an input shaft and an output shaft, wherein the input shaft is configured to receive rotational input from an electric machine. The system further includes a first gear coupled to the intermediate shaft, and a plurality of clutches coupled to the input shaft and the output shaft and configured to in a first mode, transfer power directly between a second gear coupled to the input shaft, the first gear, and a third gear coupled to the output shaft, and in a second mode, transfer power indirectly between the second gear, the first gear, and/or the third gear.

摘要： A powershift transmission of a motor vehicle has a split group with a plurality of powershift stages. An input shaft can be rotatably driven by a drive shaft of a motorized drive and transmits rotational movement in a stepped-up manner to an output shaft of the split group corresponding to one of several powershiftable stage transmissions. The powershiftable stage transmissions can be rotatably driven in a stepped-up manner by the output shaft of the split group via an intermediate group located therebetween, and via an input shaft of a synchromesh transmission group having a plurality of gear stages. A vehicle axle transmission can be rotatably driven by the output shaft of the synchromesh transmission group. The intermediate group has a multiple powershift intermediate transmission, in which each switching position the input shaft of the synchromesh transmission group can be rotatably driven by means of an associated transmission.

摘要： A method and system for operating a transmission that includes a power take off is described. The transmission selectively delivers mechanical power to the power take off from one of two electric traction motors via selective engagement of either a first or a second power take off clutch based on drive mode. The transmission also allows for powershifting between a first and second operating gear.

摘要： The invention relates to a lubricating device for controlling lubrication in a stepped transmission comprising a splitter section (10, 20) with an input shaft (I) and a main gear section (30, 40, 50, 60) with an output shaft (O) and a countershaft (C); where the splitter section (10, 20) comprises a first splitter gear set (10) connectable to the input shaft (I) by a first gear shift mechanism (23); and a second splitter gear set (20) connectable to the input shaft (I) by the first gear shift mechanism (23); and connectable to the output shaft (O) by a second gear shift mechanism (33). A lubrication arrangement for the second splitter gear set (20) is arranged to be controlled by the current positions of the first and the second gear shift mechanisms (23, 33); wherein the lubrication arrangement is controlled to at least reduce lubrication when the first and the second gear shift mechanisms (23, 33) are simultaneously connected to or disconnected from the second splitter gear set (20).

摘要： A dual-clutch transmission includes first and second partial transmissions, a first countershaft to which a first output gear is permanently connected in a rotationally fixed manner, and a second countershaft to which a second output gear is permanently connected in a rotationally fixed manner. A first idler assigned to the first partial transmission and a second idler assigned to the second partial transmission are respectively arranged coaxially to the first countershaft and are couplable to each other in a rotationally fixed manner by a bridge switching element. The first partial transmission includes exactly three single-gear planes, including a first single-gear plane, second single-gear plane having the first idler, and third single-gear plane. The second partial transmission includes exactly two single-gear planes, including a fourth single-gear plane having the second idler and a fifth single-gear plane, and which is equipped such that eight transmission gears can be implemented with a falling transmission ratio.

摘要： A dual-clutch transmission includes an odd gears clutch, an odd gears shaft supporting at least two odd-numbered rotary gears, an even gears clutch, and an even gears shaft supporting at least two even-numbered rotary gears. A driven rotary shaft is selectively connectable to one respective said odd- or even-numbered gear at a time. The dual-clutch transmission includes first and second range selection gears to transfer drive from the driven rotary shaft to an output shaft so as selectively to permit selection of at least a first range transmission ratio or a second range transmission ratio. The dual-clutch transmission further includes a first bypass drive line to drive engagement of at least two mutually engaged bypass rotary gears with the output shaft, giving rise to a first intermediate transmission ratio.
