Abstract

The stepless variable speed drive for an automobile has an input shaft (4) provided with coned discs (2) mounted on axial splines (5). The outer edges of the discs (2) are pressed between rings (3) which slide in splines (8) in the housing (7). The output shaft (13) is provided with a flange (12) which is pressed against the disc by springs (14) acting on toothed ring (17). The speed ratio of the drive is changed by shifting the input shaft sideways w.r.t. the axis of the output shaft (13). The smaller disc springs (23), reduce the shock when the engine is used as a brake and the output shaft drives the input shaft (4).
