The invention relates to a change-speed gearbox for motor vehicles, in particular manual gearboxes, having a plurality of forward gears and, optionally, one reverse gear, at least one input shaft, an output shaft and, optionally, a layshaft, between which the idler gears, which can be shifted via synchronous clutches, and the fixed gears of the gearwheel sets are arranged. At least one of the shafts (14; 16; 46) has a two-part design and is mounted in the transmission housing with mutually different axes of rotation, an annular gear stage (20) is functionally provided between the sub-shafts (14a, 14b; 16a, 16b; 46a, 46b) and comprises a internally-toothed annular gear (20a) and an externally-toothed spur gear (20b) that meshes therewith, the sub-shaft (14b; 16b; 46b) which has the larger axial distance (a1) to the other shaft (16; 14; 44) bearing gearwheels of the lower forward gears (1, 2) and, optionally, of the reverse gear (R). |
