Manual transmission for a motor vehicle

摘要

A manual transmission of a motor vehicle, is actuated by manually shifting a shift lever in a gearshift console having a selector gate and shifting gates in a multiple-H shifting pattern, with coaxial input and output shafts and a parallel countershaft, and with a number of gearset planes. Transmission gears are implemented by engaging at least two associated gear clutches. The gear clutches are divided into a selection group and a shifting group. The selection group gear clutches can be actuated exclusively by moving the shift lever in the selection gate so as to couple the input and counter-shafts. The shifting group gear clutches can be actuated exclusively by moving the shift lever in the shifting gates so as to couple the output and counter-shafts, and the gear clutch respectively engaged in the shifting gates having the two opposite gears is a selection group gear clutch.

主权项

1. A manual transmission (1) of a motor vehicle which is actuatable by a manual shifting device, the manual transmission (1) comprising:
a gearshift console (6) with a selection gate (7) in the form of a transverse slot and a plurality of shifting gates (8a, 8b, 8c, 8d, 8e) in the form of longitudinal slots for guiding a shift lever in a multiple-H shifting pattern (5); an input shaft (2); an output shaft (3) arranged coaxially with and behind the input shaft (2); a countershaft (4) arranged with an axis thereof extending parallel to the input and the output shafts (2, 3); gearwheels arranged in a number of gearset planes (a, b, c, d, e, f), which comprise fixed wheels (a2, b2, c2, d2, e2, f2) or loose wheels (a1, b1, c1, d1, e1, f1) arranged on the input shaft, the output shaft and the countershaft (2, 3, 4) or able to be coupled, in a rotationally fixed manner, to the input shaft, the output shaft and the countershaft (2, 3, 4) by gear clutches (S1, S2, S3, S4, S5, S6, S7); transmission gears being engaged by engagement, in each case, of at least two of the gear clutches (S1, S2, S3, S4, S5, S6, S7), the shifting gates (8b, 8c, 8d) that have opposite gears, in each case, one of the gear clutches (S1, S2, S3) is engaged in the two opposite gears, the gear clutches (S1, S2, S3, S4, S5, S6, S7) are divided into a selection group and a shifting group, such that:
the gear clutches (S1, S2, S3) of the selection group are exclusively actuatable by selection movements of the shift lever in the selection gate (7) so that the input shaft (2) is coupled to the countershaft (4), andthe gear clutches (S4, S5, S6, S7) of the shifting group are exclusively actuatable by shifting movements of the shift lever in the shifting gates (8a, 8b, 8c, 8d, 8e) so that the output shaft (3) is coupled to the countershaft (4), and the gear clutch (S1, S2, S3) respectively engaged in the two opposite gears in the shifting gates (8b, 8c, 8d) that have opposite gears is a gear clutch of the selection group wherein six gearset planes (a, b, c, d, e, f) are arranged so as to produce seven forward gears (1G, 2G, 3G, 4G, 5G, 6G, 7G) and at least one reverse gear (R1), all the loose wheels (a1, b1, c1, d1, e1, f1) and all the gear clutches (S1, S2, S3, S4, S5, S6, S7) are arranged on the input shaft (2) and the output shaft (3) and all the fixed wheels (a2, b2, c2, d2, e2, f2) are arranged on the countershaft (4).
