Embodiment Construction

[0066] exist figure 1 , 3 , 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27 and 29 respectively show a possible implementation of an eight-speed dual-clutch transmission. The respective shift diagrams for the different implementations are in figure 2 , 4 , 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, and 30 are shown in tabular form.

[0067] The eight-speed dual-clutch transmission includes two clutches K1 , K2 , whose input side is connected to a drive shaft w_an and whose output side is each connected to one of two transmission input shafts w_k1 , w_k2 arranged coaxially with one another. Furthermore, a torsional vibration damper 22 can be arranged on the drive shaft w_an. In addition, two intermediate shafts w_v1, w_v2 are provided, and gear gears formed as idler gears 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18 are rotatably supported in the intermediate on axis. On the two transmission input shafts w_k1, w_k2 there are gearwheels arranged in a rotationally fixed mann...

Abstract

A double clutch transmission with inputs of two clutches (K1, K2) connected to a drive shaft (wan) and output sides connected to a respective transmission input shaft (w_k1 or w_k2) positioned coaxially to each other, two countershafts (w_v1, w_v2) each having toothed idler gearwheels, toothed fixed gearwheels (1, 2, 3, 4, 5, 6) are positioned in a fixed manner on the two transmission input shafts, at least one shift element (N) is provided for connecting two toothed gear wheels with one another so that a plurality of power-shiftable forward gears and a shiftable reverse gear (R1, R2) is provided. A maximum of six gear planes (7-13, 2-14, 9-15, 4-16, 5-17, 6-18) are provided so that at least one power-shiftable winding path gear (G1, R2, O1) is shiftable by the shift element (N).

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 10305241 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 two transmission input shafts. The two transmission input shafts are arranged coaxially with each other. In addition, 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 layshaft in order to be able to engage the corresponding gearwheel. The correspondingly selected transmission ratio is transmitted to the differential via the output gear. In...
