  • Patent number: 10487872
    Abstract: A rolling bearing arrangement is provided for a switching device for switching a manual transmission. The rolling bearing arrangement includes at least one rolling bearing having an outer shell, a cage axially displaceable in the outer shell, and a plurality of rolling elements guided by the cage and radially supported on the outer shell. A rod having a switch axis is supported rotatably and axially displaceably by the rolling elements. The rod has an axial stop for securing the cage in a form-fitting manner with vertically aligned rod in an upper position against a downward axial displacement.
    Type: Grant

  • Patent number: 8117935
    Abstract: A synchronizer actuating system with selectives for use in dual clutch transmission is provided. The synchronizer actuating system includes an apply finger and a fork mounted on a shift rail. The fork grips a synchronizer sleeve that supports a synchronizer. The synchronizer is moveable to a neutral position. A three area piston assembly is operable to engage and actuate the apply finger. The three area piston assembly includes a hydraulic neutral position. A selective element is coupled to the synchronizer actuating system to calibrate the hydraulic neutral position of the three area piston assembly to the neutral position of the synchronizer sleeve.
