ABSTRACT:
A motor-vehicle transmission has a housing extending along an axis and having axially spaced front and rear sides, a main input shaft centered on the axis and having a front end at the front housing side and a rear end spaced axially backward therefrom, a main output shaft centered on the axis and having a front end at the input-shaft rear end and a rear end at the rear housing side, and a secondary countershaft adjacent the input and output shafts and having front and rear ends respectively at the front and rear housing sides. A cylindrical-roller bearing supports the output-shaft front end on the input-shaft rear end for rotation therein and prevents relative radial movement but permits relative axial movement of the input-shaft rear end and output-shaft front end. Roller-type axial-thrust bearings support the input-shaft front end, the output-shaft rear end, and one of the ends of the countershaft on the housing. A main support element braced axially rearward against the output-shaft front end and the input-shaft rear end is rotationally coupled to one of the main shafts and a main spring braced between the one main shaft and the support element urges same axially against the other main shaft. A secondary support element braced axially between the other end of the countershaft and the housing is carried in another axial-thrust bearing on the housing and is rotationally coupled to the countershaft. A secondary spring braced between the countershaft and the secondary support element urges same axially apart.
