摘要： 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.

摘要： A motor vehicle transmission includes an infinitely variable V-belt transmission having a primary (driving) pulley connected to an annular channel which is radially closed from the outside and into which a stationary pitot tube terminates for sensing the pressure of the fluid present in the channel in order to produce a fluid-pressure signal proportional to the speed of rotation of the primary pulley and further includes an input shaft which can be connected to the primary pulley through a fluid-pressure-operated driving away clutch. The input shaft of the transmission is connected to a second annular channel radially closed from the outside into which a second stationary pitot tube terminates for sensing the pressure of the fluid present in the second channel in order to produce a second fluid-pressure signal proportional to the speed of rotation of the input shaft. A fluid pressure transmitting device continuously transmits the higher one of the two fluid-pressure signals and a control device responsive to the transmitted signal regulates the fluid pressure employed for the operation of the clutch.
