Embodiment Construction
[0046] exist figure 1 , 3 , 5, 7, 9 and 11 respectively show a possible implementation of an eight-speed dual-clutch transmission. figure 2 , 4 , 6, 8, 10 and 12 show the corresponding shift diagrams for various embodiments in tabular form.
[0047] The eight-speed dual-clutch transmission comprises two clutches K1, K2, the inputs of which are connected to a drive shaft w_an and the outputs of which are each connected to one of the two coaxially arranged transmission input shafts w_k1, w_k2 connected. Furthermore, a torsional vibration damper 22 can be arranged on the drive shaft w_an. Furthermore, two countershafts w_v1 , w_v2 are provided, on which gearwheels formed as idler gearwheels 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 are rotatably mounted. On the two transmission input shafts w_k1, w_k2, the gear gears configured as fixed gears 1, 2, 3, 4, 5 are fixedly rotated and arranged, which are at least partially connected with the idler gears 7, 8, 9, 10, 11, ...

Abstract
A double clutch transmission comprising two clutches (K1, K2) the input sides of which are each connected to a drive shaft (w_an) and the output sides of which are respectively connected to one of two coaxially disposed transmission input shafts (w_k1, w_k2). Toothed idler gearwheels (8, 9, 10, 11, 12, 13, 14, 15) are mounted on the two countershafts (w_v1, w_v2) while toothed fixed gearwheels (1, 2, 3, 4) are provided on the two transmission input shafts (w_k1, w_k2) whereby several power shiftable forward gears (1, 2, 3, 4, 5, 6, 7, 8) and at least one reverse gear (R1, R2, R3) are shiftable. A maximum of five gear planes (8-12, 9-13, 10-14, 11-15) are provided so that at least one power shiftable winding path gear (G8, C3) is shifted by the shift element (M) and at least one power shiftable winding path gear (R1) is shifted by the shift element (P).
Description
technical field [0001] The invention relates to a dual clutch transmission for a motor vehicle 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 laid-open publication DE 103 05 241 A1. The dual-clutch transmission includes two clutches, each of which is connected with its input to a drive shaft and with its output to one of the two transmission input shafts. The two transmission input shafts are arranged coaxially with one another. Furthermore, two countershafts are arranged parallel to the axes of the two transmission input shafts, the idler gears of which mesh with the fixed gears of the respective transmission input shafts. Furthermore, a plurality of axially displaceable coupling devices are held rotationally fixed on the countershafts in order to be able to engage the corresponding gearwheels. The correspondingly selected transmission ratio is transmitted via the output g...
