ABSTRACT:
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.
