Embodiment Construction

[0021] A possible embodiment variant of the dual-clutch transmission is shown in the drawing by means of a seven-speed dual-clutch transmission. exist figure 2 The exemplary shift diagram for this embodiment variant is shown in a table in .

[0022] When e.g. changing several gears from figure 2 When omitted from the shift diagram, the figure 1 The gear set shown in the figure for the dual clutch transmission according to the invention can also be used without mechanical modifications for a six-speed or a five-speed dual clutch transmission.

[0023] The 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 each of two coaxially arranged transmission input shafts w_k1, w_k2, wherein the first transmission The input shaft w_k1 is assigned to the first sub-transmission and the second sub-transmission input shaft w_k2 is assigned to the second sub-transmission. The output shaft w_a...

Abstract

The invention relates to a dual clutch transmission comprising two clutches (K1, K2), the input sides of which are connected to an input shaft (w_an) and the output sides of which are connected to one of two transmission input shafts (w_k1, w_k2) that are arranged coaxially relative to each other. The dual clutch transmission comprises at least two countershafts (w_v1, w_v2) which are arranged coaxially relative to each other and an output shaft (w_ab) which is coaxially arranged relative to the drive shaft (w_an), wherein several gear planes (I, II, III, IV, V) and at least one reverse gear gear plane (R) are provided, to which several switching elements (A, B, C, D, E, F, H) for switching idler gears (3, 5, 7, 10, 11) and / or shaft connections are associated so that several forward gears (V1, V2, V3, V4, V5, V6, V7) and at least one reverse gear (R1) can be shifted. According to the invention, five gear planes (I, II, III, IV, V) are arranged in such a manner that at least seven forward gears (V1, V2, V3, V4, V5, V6, V7) can be shifted under load.

Description

technical field [0001] The invention relates to a dual clutch transmission according to the type defined in detail in the preamble of claim 1 . Background technique [0002] For example, DE 10 2007 037 568 A1 discloses a dual clutch transmission with seven or eight forward gears and two reverse gears. In this dual-clutch transmission, the input shaft is connected to the main shaft via a first sub-transmission and a second sub-transmission, which are arranged parallel to one another in the force flow diagram. Each subtransmission is assigned a frictionally engaging power shift clutch and an countershaft in each case, wherein the countershaft axes are arranged concentrically with respect to one another. In addition, four shifting elements acting on both sides are provided, each with a sliding sleeve, in order to be able to shift different gears. In order to be able to realize power shiftable gears, the dual clutch transmission must include six gear planes and additionally a ...
