Embodiment Construction

[0039] a press figure 1 The transmission for automobiles has six gear set planes a, b, c, d, e, f and seven gear clutches S1, S2, S3, S4, S5, S6, S7. Depend on figure 2 The transmission structure can be easily seen.

[0040] The transmission 1 is designed as an intermediate shaft transmission comprising a drive-side input shaft 2 , a driven-side output shaft 3 arranged coaxially behind the input shaft, and an intermediate shaft 4 arranged axially parallel to these transmission shafts 2 , 3 .

[0041] The six gear set planes a to f are respectively formed as spur gear pairs a1 / a2, b1 / b2, c1 / c2, d1 / d2, e1 / e2, f1 / f2 in meshing toothing, with the last gear set plane f A steering reversal gear f3 with a rotatable bearing is added in order to enable the respective reverse gears. The spur gear pairs a1 / a2, b1 / b2, c1 / c2, d1 / d2, e1 / e2, f1 / f2 respectively have: idler gears a1, b1, c1, d1, e1, f1, which are rotatably supported on On the input shaft 2 or the output shaft 3 and can be...

Abstract

The invention relates to a transmission (1) for a motor vehicle. Gear clutches (S1, S2, S3, S4, S5, S6, S7) are divided into a selection group and a shifting group. The selection group gear clutches (S1, S2, S3) can be actuated exclusively by moving a shift lever in the selection gate (7) so as to couple an input shaft (2) and a counter shaft (4). The shifting group gear clutches (S4, S5, S6, S7) can be actuated exclusively by moving a shift lever in the shifting gates (8a, 8b, 8c, 8d, 8e) so as to couple an output shaft (3) and the counter shaft (4), and the gear clutch (S1, S2, S3) respectively engaged in the shifting gates (8b, 8c, 8d) having the two opposite gears is a selection group gear clutch.

Description

technical field [0001] The invention relates to a motor vehicle transmission according to the preamble of claim 1 . Background technique [0002] Transmissions have been used for a long time in the powertrains of motor vehicles, which are constructed in the manner of a countershaft and which can be actuated by manual shifting. In conventional countershaft transmissions, idler gears and fixed gears are provided in multiple gear set planes, which are in tooth meshing in pairs. In particular, the switching of the transmission gear is realized by opening the first gear clutch of the connected gear and closing the gear clutch of a target gear, and the non-relatively rotatable connection between an idler gear and a transmission wheel is disengaged at this time, involving The idler gear is rotatably supported on the transmission shaft, creating another non-rotatable connection between an idler gear and a transmission shaft. The rotating components of the target gear to be engaged...
