A transmission mechanism for automotive vehicles or other machines, which comprises a drive shaft, a friction-type, single-stage variable-speed system comprising internally tangent male and female disks adapted to be clamped together by means of a fluid-actuated piston, wherein at least one driving male disk rigid with the input shaft of the variable-speed system is interposed between female disks rotatably solid with a drum adapted to rotate about the axis of said male and female disks, a disk clutch adapted to be engaged by the action of a plate, dog means permitting the change from forward motion to reverse motion of the vehicle, said transmission mechanism being characterized in that the piston for clamping the variable-speed disks is axially movable within the bore of said drum carrying the clutch disks and the driven disks of said variable-speed system, and that said drum is axially movable in relation to said clutch disk clamping plate.
