Abstract

In the case of a vehicle transmission (2) with two counter shafts placed in a transmission housing (8) for the distribution of load, with one input shaft (4) and one main shaft (20) coaxially aligned with the input shaft (4), a gear (24) is placed in the area between the input shaft (4) and the main shaft (20). The gear (24) is secured by a bearing (26, 28) between the input shaft (4) and the main shaft (20) and secured radially by bearings between the two counter shafts. The bearing (26, 28) constitutes the exclusive axial bearing between the input shaft (4) and output shaft (20). The axial bearing comprises two axial effective roller bearings (26, 28) which lie on opposed sides of a projection (30) of the gear (24).
