Patent ID: 10816061

Abstract:
The invention proposes a dual-clutch transmission with two clutches (K1, K2), the input sides of which are connected with an input shaft (w_an) and the output sides of which are respectively connected with one of two coaxially disposed transmission input shafts (w_K1, w_K2). Further provided are at least two countershafts (w_v1, w_v2) on which idlers (i2, i3, i4, i5, iR) are rotatably mounted. The dual-clutch transmission comprises fixed gears (F1, F2, F3), which are disposed on the two transmission input shafts (w_K1, w_K2) in a rotationally fixed manner and in engagement with the idlers, and output gears (iab1, iab2) respectively provided on the two countershafts (w_v1, w_v2), each of which is coupled to a gearing of an output shaft (w_ab), wherein the output shaft (w_ab) is not coaxially disposed to the input shaft (w_an). A plurality of shift elements (S1, S2, S3) is provided as well, so that at least six power-shiftable forward gears (1, 2, 3, 4, 5, 6) and at least one reverse gear (R1, R2) are shiftable. Only three double-acting shift elements (S1, S2, S3) are provided according to the invention, wherein two idlers (i2, i3, i4, i5, iR) of the countershafts (w_v1, w_v2) are allocated to each double-acting shift element (S1, S2, S3), wherein, in a first operating direction (S1a), one of the shift elements (S1) connects an idler (i3) with the associated countershaft (w_v1) and, in a second operating direction (S1b), connects the two associated idlers (i3, i4) with one another, and wherein two shift elements (S2, S3) respectively connect the associated idlers (i2, i5; i4, iR) with the associated countershafts (w_v1, w_v2) in a rotationally fixed manner.
