1. dual-clutch transmission, has:

  • i.e. one first clutch (K1) of two clutches (K1, K2) and second clutchDevice (K2), input side and a drive shaft (w_an) of described clutch (K1, K2) are connected, and the outlet side of described clutchRespectively with i.e. one the first transmission input shaft (w_K1) of two transmission input shafts being mutually coaxially disposed (w_K1, w_K2) andOne in one the second transmission input shaft (w_K2) is connected;

    At least two jackshaft (w_v1, w_v2) i.e. at least oneFirst jackshaft and second jackshaft, rotatably support on described first jackshaft and the second jackshaft and be configured to emptySix shift gears of sleeve gear (5,6,7,8,9,10);

    Two transmission input shafts (w_K1, w_K2) rotationally fixedly setThat put and be configured to four shift gears of fixed gear (1,2,3,4), described fixed gear at least in part with described empty setGear (5,6,7,8,9,10) is meshed;

    Multiple couplings (A, B, C, D, E, F), be used for making free gear (5,6,7,8,9,10) rotationally fixedly it is connected with jackshaft (w_v1, w_v2);

    The each output being arranged on two jackshafts (w_v1, w_v2)Gear (12,13), described output gear teeth portion with an output shaft (w_ab) respectively engages;

    Wherein, can turn on multiple motilityThe forward gear (G1, G2, G3, G4, G5, G6) of gearshift and at least one reverse gear shift (R1, R2, R3, R4, R5);

    It is characterized in that, shouldDual-clutch transmission has 4+1 the gear plane with 13 shift gears provides at least 7+2 individual and before at most 7+4Entering gear, wherein the gear stage (i_3) of the 3rd forward gear (G3) and the gear stage (i_5) of the 5th forward gear (G5) are disposed in one respectivelyIndividual individual gears plane (5-1,2-8), in described individual gears plane, a free gear (5,8) of jackshaft (w_v1, w_v2)It is disposed in a fixed gear (1,2) of one of transmission input shaft (w_K1, w_K2), the gear stage (i_2) of the second forward gear,The gear stage (i_R) of the gear stage (i_4) of the 4th forward gear, the gear stage (i_6) of the 6th forward gear and reverse gear shift is disposed in twoIndividual Double-gear plane (6-9,7-10), in each Double-gear plane (6-9,7-10), first and second jackshaft (w_v1, w_V2) each free gear (6,9;

    7,10) fixed gear of one of transmission input shaft (w_K1, w_K2) it is disposed in(1、

    2、

    3、

    4);

    Wherein, in each Double-gear plane (6-9,7-10), at least one free gear (6,9;

    7,10) can be used forAt least two gear, thus at least one the roundabout gear of power shifting can pass through at least one first switching device (K)And/or by the coupling (S_ab2) of at least one output gear (13) being disposed in the second jackshaft (w_v2) openedConnect.
