Embodiment Construction

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

[0067] The eight-speed dual-clutch transmission includes two clutches K1, K2, the input side of which is connected to a drive shaft w_an, and its output side is respectively connected to one of the two coaxial transmission input shafts w_k1, w_k2 connect. Furthermore, a torsional vibration damper 22 can be arranged on the drive shaft w_an. In addition, there are two countershafts w_v1, w_v2, gear gears formed as idler gears 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18 are rotatably mounted on the on the intermediate shaft. The gearwheels arranged in a rotationally fixed manner on the two transmission input shafts w_k1 , w_k2 and designed a...

Abstract

A double clutch transmission with two clutches (K1, K2) which each have input sides connected with an input shaft (w_an) and output sides respectively connected with one of two coaxially arranged transmission input shafts (w_k1, w_k2). At least two countershafts (w_v1, w_v2) are provided on which are mounted idler gearwheels (8, 9, 10, 11, 12, 13, 14, 15) while, on the two transmission input shafts (w_k1, w_k2), are mounted fixed gearwheels (1, 2, 3, 4, 5). At least several power-shiftable forward gears and at least one reverse gear are shiftable by the transmission. Five gear planes (8-12, 9-2, 3-13, 10-14, 11-15) are provided so that at least one power-shiftable winding path gear can be shifted via at least one shift element (M).

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. Furthermore, two countershafts are arranged with axes parallel to the two transmission input shafts, the idler gears of which mesh with the fixed gears of the transmission input shafts. In addition, the coupling device is fixed axially displaceable on the intermediate shaft in a rotationally fixed manner in order to be able to engage (shift) the corresponding gearwheel. The correspondingly selected transmission ratio is transmitted to the differential via the output gear. In ...
