Problems solved by technology

Due to torsional vibrations, in particular caused by the drive, the tooth flanks of intermeshing unloaded gears can collide with each other within a given backlash, which leads to undesired rattling noises

Embodiment Construction

[0027] figure 1 A gear set for a shift transmission of a motor vehicle is schematically shown. The shift transmission has an input shaft 10 , which is connected on the drive side or engine side 1 , preferably via a clutch, to a drive or engine (not shown here) of the motor vehicle. The output shaft 30 is arranged parallel to the input shaft 10 . Furthermore, the shift transmission has an additional shaft 50 which is likewise arranged parallel to the input shaft 10 .

[0028] Six fixed gear wheels 11 , 12 , 13 , 14 , 15 and 16 are arranged on the input shaft 10 . In this case, the fixed gear 11 meshes with an idler gear 31 arranged on the first output shaft 30 . Further idler gears, ie idler gears 32 , 33 , 34 , 35 and 36 , are located on output shaft 30 . The idler gear 31 is non-rotatably connected to the output shaft 30 via a shift clutch 37 designed as a double shift clutch. In this case, the double clutch 37 has a sliding sleeve 38 which, starting from the neutral pos...

Abstract

The invention relates to a transmission for a motor vehicle, comprising an input shaft (10) and an output shaft (30), fixed gears (11 to 16), idler gears (31 to 36), and gear couplings (37, 40, 41) for the rotationably fixed connection of the idler gears (31 to 36) to the input shaft (10) or the output shaft (30), a plurality of gears (I to VI), wherein one of the idler gears (31 to 36) and one of the gear couplings (37, 40, 41) is assigned to each gear. The idler gear is connected in a rotatably fixed manner to the shaft bearing the idler gear by way of the gear coupling, whenever the corresponding gear is engaged. The transmission further comprises a ring gear (2) meshing with a first pinion (39) arranged on the output shaft (30), an additional shaft (50), on which a second pinion (52) that meshes with the ring gear (2), an additional toothed gear (51), and an additional gear coupling (53) are arranged, wherein the additional shaft (50) and the additional gear coupling (53) are assigned to an additional gear. The transmission is characterized in that the second pinion (52) is rotatably arranged on the addition shaft (50), and when the additional gear engaged, is connected to the second pinion (52) in a rotationally fixed manner.

Description

technical field [0001] The invention relates to a shift transmission for motor vehicles, which comprises an input shaft, an output shaft and a fixed gear, an idler gear and a gear for non-rotatably connecting the idler gear with the input shaft or the output shaft Shift clutch. Background technique [0002] Such a shift transmission is known, for example, from EP 0 560 202 B1. The shift transmission has six forward gears and one reverse gear. In this case, each gear is assigned an idler gear and a shifting clutch, wherein when the corresponding gear is engaged, the idler gear is non-rotatably connected via the shifting clutch to the shaft carrying the idler gear . For example, in the embodiment of EP 0560 202 B1, a first forward idler gear arranged on the output shaft meshes with a fixed gear on the input shaft. The shift clutch associated with the first gear (first forward gear) is part of a double shift clutch via which the idler gear of the second forward gear can als...
