Embodiment Construction

[0030] The seven-speed dual-clutch transmission of the present invention includes two clutches K1, K2, the input ends of which are connected to a drive shaft w_an. Furthermore, a torsional vibration damper 17 can be arranged on the drive shaft w_an. The outputs of the clutches K1 , K2 are each connected to one of two coaxially arranged transmission input shafts w_K1 , w_K2 . The first transmission input shaft w_K1 is designed as a solid shaft, and the second transmission input shaft w_K2 is designed as a hollow shaft. Furthermore, two countershafts w_v1 , w_v2 are provided, which are arranged axially parallel to one another. The coupling of the two transmission input shafts w_K1 and w_K2 takes place here with shift elements L and M via gear meshing, so that the transmission input shafts w_K1 and w_K2 are relative to each other.

[0031] In the seven-speed dual clutch transmission according to the invention, only five gear planes are provided. in accordance with figure 1 In...

Abstract

A double clutch transmission with two clutches connected to a drive shaft and to one of two transmission input shafts. Fixed gears are coupled to the input shafts and engage idler gears. Several coupling devices connect the idler gears to a countershaft which have an output gear that couple gears of an output shaft such that at least seven power shift forward gears and at least one reverse gear can be shifted, and four gear wheel planes are arranged in such a way that at least one power shift winding-path gear can be shifted via the shifting device, such that at least seven power shift forward gears and at least one reverse gear can be shifted, and five gear planes are positioned in such a way that at least one power shift winding-path gear can be shifted via a shifting device.

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 each of two transmission input shafts. The two transmission input shafts are arranged coaxially with one another. Furthermore, two countershafts are arranged axially parallel to the two transmission input shafts, the idler gears of which mesh with the fixed gears of the respective transmission input shafts. In addition, a plurality of axially displaceable coupling devices are mounted on the countershafts in a rotationally fixed manner in order to be able to engage the corresponding gearwheels. The correspondingly selected transmission ratio is transmitted via the ...
