Abstract: A dual clutch transmission including two sub-transmissions, each having an input shaft arranged on an input axis, an intermediate shaft and an output shaft which is the drive output of both sub-transmissions. The intermediate shaft can be connected to the input and output shafts. The transmission also has wheel planes, shifting elements, two clutches and countershafts. A first countershaft can be connected to transmission elements of all the wheel planes on the countershaft axis and a second countershaft is connected to transmission elements of at least two wheel planes. The shifting elements include at least one single shifting element, but most of the shifting elements are double shifting elements. Two shifting elements are arranged on the input axis between two wheel planes, whose transmission elements are connected to the second countershaft. Opposite sides of the intermediate shaft are respectively connected to a range group and the output shaft.

Abstract: A cooling assembly fluidly communicating with a vehicle cooling system includes a coolant tube and a mounting plate. The cooling assembly is configured for cooling a support bearing disposed in a dual clutch transmission. The coolant tube includes (i) an inlet end that receives a cooling medium, (ii) an outlet end that returns the cooling medium to the vehicle cooling system and (iii) a heat transfer portion incorporated between the inlet end and the outlet end. The mounting plate has a plate body including a bearing opposing surface and a transmission housing opposing surface. The bearing opposing surface contacts the support bearing. The heat transfer portion of the coolant tube is attached to the mounting plate such that cooling medium communicated through the coolant tube reduces temperature of the mounting plate and therefore the support bearing.

Abstract: A constant mesh gear transmission has an input shaft (21, 22), two layshafts (31, 35) and an output shaft (23). Gear wheels are selectively connectable to shafts to provide forward and reverse speed ratios. A common central web (39) provides central support bearings for the shafts. The transmission is stiffened, and allows assembly of components from either end to the middle.

Abstract: A multi-speed, dual clutch transmission includes an input shaft, an output shaft, and first and second countershafts. The first and second countershafts are axially displaced from the input shaft, the output shaft and from one another. Four intermeshing gear pairs, an interconnecting gear set having first, second and third members, a first single gear and an idler gear, some of which are engageable with at least some of the shafts via a first clutch, a second clutch, and six torque-transmitting mechanisms, establish eight forward speed ratios and one reverse speed ratio. Furthermore, shifting between the forward speed ratios is dynamic.
