Embodiment Construction

[0071] exist figure 1 , 3 , 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33 and 35 respectively show possible implementations of the eight-speed dual clutch transmission. The corresponding shift diagrams for different implementations are in figure 2 , 4 , 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34, and 36 are represented graphically.

[0072] The eight-speed dual-clutch transmission includes two clutches K1 , K2 , whose input sides are connected to the drive shaft w_an and whose output sides are each connected to one of two transmission input shafts w_k1 , w_k2 arranged coaxially with one another. Furthermore, a torsional vibration damper 19 can be arranged on the drive shaft w_an. In addition, two countershafts w_v1 , w_v2 are provided, on which gearwheels in the form of idler gears 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 are rotatably mounted. On the two transmission input shafts w_k1 , w_k2 , gearwheels in the form of fixed gearwheels 1 , 2 , 3 , 4 ,...

Abstract

A double clutch transmission with two clutches with input sides connected to a drive shaft and output sides each respectively connected to one of two transmission input shafts arranged coaxially with each other. At least two countershafts on which toothed idler gearwheels are rotatably supported. There are toothed fixed gearwheels arranged on the two transmission input shafts in a rotationally fixed manner. At least one first shift element is provided for connecting two idler toothed gears in a rotationally fixed manner whereby at least several power-shift forward gears at least one reverse gear are capable of being implemented. There are a maximum of seven gear planes so that at least one winding path gear is shifted with a disengaged first output coupling device that is allocated to the first power take-off gear.

Description

technical field [0001] The invention relates to a dual clutch transmission of the type specified in the preamble of claim 1 . Background technique [0002] A six-speed or seven-speed dual clutch transmission is known from DE 103 05 241 A1. The dual clutch transmission comprises two clutches which are each connected with their input sides to a drive shaft and with their output sides to each of the two transmission input shafts. The two transmission input shafts are arranged coaxially with each other. The other two countershafts are arranged with axes parallel to the two transmission input shafts, and the idler gears of the two countershafts mesh with the fixed gears of the transmission input shafts. In addition, the coupling device is fastened in an axially displaceable, rotationally fixed manner on the countershaft in order to be able to engage the corresponding gearwheel. The correspondingly selected transmission ratio is transmitted to the differential via the output ge...
