Embodiment Construction

[0024] The gearbox 1 , which is constructed as a double clutch gearbox, has a first input shaft 2 with a first gear set 3 and a second input shaft 4 with a second gear set 5 and a gearbox with corresponding gear sets 7 , 8 . Driven shaft 6 with gears in first gear set 3 meshing with gears in third gear set 7 and gears in second gear set 5 meshing with gears in fourth gear set 8 . The driven wheel is denoted by reference numeral 9 . The first input shaft 2 can be driven by the drive shaft 11 of the internal combustion engine 15 via the first shifting clutch 10 , and the second input shaft 4 can be driven by the drive shaft 11 of the internal combustion engine 15 via the second shifting clutch 12 . Therefore, two different primary transmissions 13, 14 can be used to drive the input shafts 2, 4, wherein the primary transmissions 13, 14 can have different gear ratios. Use G1, G2, G3, G4, G5, G6 to represent the gears.

Abstract

The invention relates to a transmission (1) for a vehicle, embodied as a twin-clutch transmission, the toothed wheels being combined to form groups of toothed wheels (3, 5) arranged on input shafts (2, 4) and on an output shaft (6). The toothed wheels pertaining to the toothed wheel groups (3, 5) of the input shafts (2, 4) are permanently engaged with the toothed wheels of at least one toothed wheel group (7, 8, 16) of the output shaft (6), and a first input shaft (2) is connected to a drive shaft (11) of a drive motor by means of a first clutch (10), and a second input shaft (4) is connected to a drive shaft (11) of a drive motor by means of a second clutch. The aim of the invention is to enable a compact construction, low production costs, and rapid shifting times. To this end, a first primary gear (13) is arranged between the drive shaft (11) and the first input shaft (2), and a second primary gear (14) is arranged between the drive shaft (11) and the second input shaft (4). Preferably, the first and second primary gears (13, 14) have different gear ratios.

Description

technical field [0001] The invention relates to a vehicular gearbox configured as a double clutch gearbox in which gears are combined into a gear set arranged on an input shaft and a driven shaft, wherein the gears in the gear set of the input shaft and the driven shaft The gears in at least one gear set of the shaft are permanently meshed, and wherein the first input shaft can be connected to the drive shaft of the engine through a first shift clutch and the second input shaft can be connected to the drive shaft of the engine through a second shift clutch. connect. Background technique [0002] In DE 198 07 374 A1 a double clutch gearbox is disclosed, in which the gears of the gearbox are combined into gear sets on which shifting elements act. In this case, the shifting clutches are arranged on different end faces of the clutches and are driven by a single engine. In this case, the shifting element for shifting between the different gears is designed in such a way that it...
