Abstract
A transmission mechanism in particular for automobiles with a front wheel drive comprises a planetary forward-reverse gear set and a continuously variable pulley drive that is drivingly connected to a differential gearing. A forward friction disk clutch provided for obtaining a forward driving direction of the transmission mechanism may be selectively operated by a servo piston that is fixedly connected in an axially stationary manner to the adjusting piston of a hydraulic adjusting means provided for the selective adjustment of the movable sheave of a primary pulley of said pulley drive whereby the mutual arrangement is chosen in such a manner that the adjusting cylinder being fixedly connected to this movable sheave at least partly surrounds the servo piston. By this particular arrangement the axial dimension of the entire transmission mechanism may be reduced without the requirement of a separate starting clutch for the entire clutch assembly.
