Vehicle gearbox

A vehicle gearbox with an input shaft (9), a drive shaft (10) and a countershaft (11), the countershaft (11), is arranged parallel to an axis of the input and drive shafts (9 and 10) and can be connected power-wise over a first, second, third, fourth, fifth and sixth gear sets (I, II, III, IV, V and VI) and reversing near set (W) by means of a plurality of separating clutches (a, b, C, d, e, f and g), wherein a main gearbox group (28) has the first, second, third, fourth and reversing gear sets (I, II, III, IV and W), each respectively having an idler (20, 21, 22, 23, and 26) and a fixed gear (13, 14, 15, 16, and 19), and a downstream area gearbox group (29) has the fifth and sixth gear sets (V and VI) each respectively having an idler (24 or 25) and a fixed gear (17 or 18), the separating clutches (a, b, c, d, and g) and the idlers (20, 21, 22, 23, 26) of the main gearbox group (28) are arranged on the input shaft (11), the idlers (24 and 25) of the range gearbox group (29) are arranged on the countershaft (11), and wherein a gearbox schematic, a shifting mechanism and a gearbox housing for a vehicle gearbox with six forward gears (1 through 6) are equivalent to a gearbox schematic, a shifting mechanism and a gearbox housing for a vehicle gearbox with eight forward gears (1 to 8).
