  • Automatic selector of a motor vehicle epicyclic change-speed gearbox
    Patent number: 5246407
    Abstract: In an automatic selector device of an epicyclic change-speed gearbox, a frictional connection, i.e. a clutch or brake, participating in the selection of a forward gear is engaged by a pressure medium setting element and disengaged by a spring device. In a neutral selection condition, a partial quantity of the pressure medium filling of the selector setting element is accommodated in a pressure reservoir so that the friction surfaces are just unloaded and does not transmit torque.
