Embodiment Construction

[0045] exist figure 1 , 3 , 5, 7 and 9 respectively show a possible implementation of the eight-speed dual clutch transmission. exist figure 2 , 4 , 6 and 8 diagrammatically show the corresponding shift diagrams for the different embodiments.

[0046] The eight-speed dual-clutch transmission comprises two clutches K1, K2, whose input side is connected to the drive shaft w_an, and whose output side is connected to one of the two transmission input shafts w_k1, w_k2 arranged coaxially with each other. Transmission input shaft connection. Furthermore, a torsional vibration damper 19 can also be arranged on the drive shaft w_an. Furthermore, two countershafts w_v1 , w_v2 are provided, on which gearwheels formed as idler gearwheels 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 are rotatably mounted. On the two transmission input shafts w_k1 , w_k2 , gearwheels designed as fixed gearwheels 1 , 2 , 3 , 4 , 5 , 6 are arranged in a rotationally fixed manner, said gearwheels being at least...

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 disposed coaxially to one another. At least two countershafts are provided upon which toothed idler gearwheels are mounted in a rotatable manner and toothed fixed gearwheels are disposed on the two transmission input shafts in a rotationally fixed manner. At least one shift element is provided for connecting two idler gearwheels in a rotationally fixed manner such that at least several power shiftable forwards gears and / or at least one reverse gear can be shifted. A maximum of six gear planes are provided so that at least one power shiftable winding path gear can be shifted using the at least one shift element.

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 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 order to real...
