Abstract:
A continuously variable transmission for motor vehicles comprising:a hollow primary shaft; a first cone pulley pair located on the primary shaft and the first cone pulley pair having a stationary primary pulley and a movable primary pulley which is movable in an axial direction relative to the stationary primary pulley by a pressurize medium supplied to an adjustment space of the movable primary pulley for moving the movable primary pulley toward the stationary primary pulley; a housing supporting the primary shaft and the first cone pulley pair, and the housing having an opening sealed by a removable cover; an electronic control unit for determining a pressure level of a pressure medium supplied to the adjustment space of the movable primary pulley; a projection, provided on an inwardly facing surface of the removable cover, communicating with a hollow end of the primary shaft located adjacent the removable cover, and the projection has a conduit extending therethrough; a primary pressure line extending substantially radially toward a center of the primary shaft to supply the pressure medium to an inner cover which facilitates with supplying the pressure medium along an exterior surface of the projection of the removable cover to the adjustment space of the movable primary pulley; and the conduit of the projection of the removable cover communicates with a lubrication line to supply a lubricating pressure medium to the hollow primary shaft.
