  • Device for guiding a moveable conical pulley disc of a CVT variator
    Patent number: 6997834
    Abstract: A device, in a continuously variable belt transmission system, for guiding a conical pulley (3) of a variator on a variator shaft (1). The moveable conical pulley (3) is fitted onto two bearing sections (4, 5) of the variation shaft (1). At least one cylindrical pin (6), which is fitted into an axial guide grove (7) in the variator shaft (1) and an axial guide groove (8) of the movable conical pulley (3), is provided to transfer torque between the movable conical pulley (3) and the variator shaft (1).

  • Variator
    Patent number: 6840876
    Abstract: A variator for ratio adjustment of a continuously variable chain drive transmission having one variator shaft (1) and one variator pulley (2) supported upon the variator shaft (1) and axially movable by pressurizing a variator pressure chamber (31). The variator shaft (1) has on one end an axial hole (10) through which the variator pressure chamber (31) and a second pressure chamber (8) can be loaded with pressure independent of each other. The pressure is supplied to the variator pressure chamber (31) via a first section (13) of the axial hole (10) and the pressure is supplied to the second pressure chamber (8) via a non-rotating pipe (7) and a second section (15) of the axial hole (10), the pipe (7) is situated within the first hole section (13).
