  • Patent number: 6845690
    Abstract: A transmission system for a motor vehicle, which contains a vehicle transmission equipped for longitudinal installation with a gear output shaft that points in the direction of the rear of the motor vehicle in the installed state is provided, wherein the shaft can be connected and be supported for rotation on an input shaft of a front axle gear unit via a driven shaft of a lateral drive unit and via a cardan shaft. For the purpose of reducing at least one deflection angle of the cardan shaft, at least one shaft corresponding to the cardan shaft is swiveled towards the gear output shaft of the vehicle transmission system.
    Type: Grant

  • Patent number: 4730713
    Abstract: In a plate clutch, an annular cylinder chamber with a moveable annular cylinder portion is located in a transition region between a radial flange and a cylindrical external plate carrier integral with the radial flange. The position of the annular cylinder portion is fixed in the radial and axial directions relative to the external plate carrier by the flange which fixes the annular cylinder in one axial direction of the clutch axis and by means of a circlip in the other axial direction of the clutch axis. In order to improve the sealing of the working pressure chamber enclosed by the annular cylinder portion, the annular cylinder is supported in the radial directions by means of a ring seal, so that it can move and be also elastically carried on the external plate carrier.

  • Patent number: 4628795
    Abstract: A piston for actuating a brake-band end of a transmission band system includes a piston for actuating a band in a transmission. The piston includes a piston body, and an elongated guide shaft having a proximal end fixed to one side of the piston body and a distal end defining a first annular support surface. The guide shaft is formed to include an axial bore having an opening in the first annular support surface. The piston further includes a piston rod having an outer end for engaging the transmission band, an inner end for reception in the axial bore, and a second annular support surface situated to confront the first annular support surface when the inner end of the piston rod is received in the axial bore of the elongated guide shaft. An O-ring is positioned along the inner end of the piston rod, to retain the inner end within the axial bore of the elongated shaft.

  • Patent number: 4534457
    Abstract: In a multi-disc clutch or brake, several lamellae in the form of annular discs cannot only be fixed essentially non-rotatably, relative to a lamella carrier fixed in terms of rotation in relation to one of the two clutch or brake parts, by means of a releasable positive connection but can also each be supported radially exclusively at an individual point on the lamella carrier, each by means of its own resilient clamping means, the clamping means being retained on the lamella carrier. At least one central annular gap located, in the peripheral direction of the axis of rotation, between two engaging teeth of the positive connection and open in the two directions of the axis of rotation is limited radially in one directions by a cylindrical shell portion of a lamella and in the other direction by a cylindrical shell portion of the lamella carrier. The engagement surface of the clamping means, used for the purpose of support, is located in the annular gap and interacts with the shell portion of the lamella.
