ABSTRACT:
A linear mechanical variator or stepless variable speed drive of the type wherein the transmission ratio between two members or shafts is varied by increasing or reducing the center distance between a radial discs unit of the variator associated with one of said shafts, and a roller crown unit of the variator, associated with the other of said shafts, the rollers being interposed between the discs. The variator further comprises: a sleeve portion on one of said shaft, a disc-holder shaft carrying an end disc of said radial discs, a bush sliding on said disc-holder shaft and carrying a second end disc of said radial discs, possible intermediate discs being located between said end discs; said discs being of tapering shape; said bush and disc-holder shaft being slightly spring urged to a position of approach for the end discs; means carried on one element, disc-holder shaft or bush, to engage the other element, and a cam on said sleeve; an edge of said sleeve acting against on the other of said elements, the whole being arranged to provide the adherence pressure of the discs on the rollers as a function of the transmitted torque.
