Embodiment Construction

[0029] Two possible embodiment variants of the dual clutch transmission according to the invention are shown by way of example in the drawing. For example, a dual-clutch transmission with nine or eight gears preferably has two reverse gears R1 and R2, wherein, in addition to other load-controlled gears, at least the first eight forward gears can be implemented sequentially load-shiftable and in addition at least one forward gear The block can be realized as a direct block. However, the number of gears described is merely exemplary, so that other gear stages can also be provided without difficulty.

[0030] Irrespective of the variants, the dual clutch transmission comprises two clutches K1, K2, whose input side is connected to the drive shaft w0, and whose output side is connected to the two transmission input shafts of the two partial transmissions arranged coaxially with one another. One connection for each of w1 and w2. The first transmission input shaft w1 is, for exampl...

Abstract

A double clutch transmission with two clutches (K1, K2) is proposed in which each clutch inputs is connected with a drive shaft (w0) and the clutch outputs are respectively coupled with two, coaxial positioned transmission input shaft (w1, w2) of partial transmissions. The double clutch transmission comprises two counter shafts (w3, w6), coaxial positioned with respect to one another. Each partial transmission has several, shiftable gear ratio steps assigned thereto which each can be coupled with the output shaft (w5), via the assigned counter shaft (w3, w6) and via a main shaft (w4) which is linked to an input section of a planetary transmission which is designed as range group, The output shaft (w5) is positioned coaxially with respect to the driveshaft (w0). At least one shiftable gear ratio step, of at least one of the partial transmissions, can be coupled with the output shaft (w5) independent from the range group.

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] For example, DE 10 2005 044 068 A1 discloses a load-shiftable combined transmission with a double clutch, in which a drive shaft and an output shaft are arranged coaxially with one another. The transmission input shafts assigned to the two partial transmissions each mesh with one of the countershafts via input constants, wherein the countershafts are arranged coaxially with one another. Furthermore, the known transmission also includes a main shaft, which can be coupled to one of the transmission input shafts for shifting direct gears. The output-side end of the main shaft is connected to the sun gear, which forms the input part of a range group configured as a planetary gear. The planet carrier is connected in a rotationally fixed manner to the transmission output shaft or driven shaft. All gears are therefore transfe...
