Embodiment Construction

[0019] figure 1 A shift transmission, generally designated 1, is shown. The shift transmission 1 has an input shaft 10 and two output shafts 30 , 50 arranged parallel to the input shaft. exist figure 1 The lower output shaft in the illustration of is marked as the first output shaft 30 here, figure 1 The upper output shaft in the illustration is designated as the second output shaft 50 .

[0020] Fixed wheels 11 , 12 , 13 , 14 , 15 and 16 are arranged on input shaft 10 . The fixed wheel 11 here meshes with a driven wheel 31 arranged on the first output shaft 30 . Further runners, namely runner 32 , runner 33 and runner 34 , are arranged on first output shaft 30 . The other runners are arranged on the second output shaft 50 , these being the runner 51 , the runner 52 and the runner 53 .

[0021] The first drive wheel 31 and the second drive wheel 32 are non-rotatably connected to the first output shaft 30 via a first double-shift clutch 35 . The first double-shift clutch...

Abstract

The gearbox (1) has two output shafts (30, 50) connected with forward gears (I-VI) or a reverse gear (R) in a torque-proof manner when the appropriate gear is inserted. A switchable unit comprises two double-gear clutches (35, 36) that are arranged on one of the output shafts. A single gear clutch (55) is located on the other output shaft. Each of a set of fixed wheels (11-15) is meshed with each of a set of idle gears (31-34, 51-53) of the forward gears. The idle gears of the one of the forward gears are meshed with the idle gears of the reverse gear. The idle gears are designed as gradated gear wheels.

Description

technical field [0001] The invention relates to a shift transmission for a vehicle, comprising an input shaft, a first output shaft and a second output shaft, wherein a fixed wheel is arranged on the input shaft without relative rotation and is connected to the first output shaft. shaft or the pulley on the second output shaft engages. Background technique [0002] Such a shift transmission is known, for example, from DE 41 16 189 C2. The driving wheel can be non-rotatably connected with the first output shaft or the second output shaft through a shiftable device. Wherein, the shiftable device includes a first double-speed clutch and a second double-speed clutch, and the two shift clutches are arranged on the first output shaft. Furthermore, a third gear clutch and a further gearshift clutch are provided, which are arranged on the second output shaft. With the gear set proposed in patent document DE 41 16 189 C2, a shift transmission with six forward gears and one reverse...
