Patent attributes
A transmission (1) having at least one transmission input shaft (4), at least one countershaft (5), one reverse gear shaft (30) and at last one transmission output shaft (6) in which, upon at least one transmission input shaft and at least one countershaft, idler gears designed as helical-cut spur gears are supported and fixed gears are fastened which forming gear pairs are in tooth contact with each other, and having shifting sets (32, 33, 34, 35) situated on the transmission input shaft and the countershaft. To implement a low shaft deflection, it is posed that the helix angles (39, 40, 42, 43) of the toothings of gear wheels (21, 22, 24, 25) driving the countershaft and the helix angle (41) of the driven gear wheel (23) on the countershaft be selected so that the toothing forces and bending torques resulting therefrom which act on the countershaft dissolve at least partly in relation to the shaft.
