    摘要: A switching device for a motor vehicle transmission includes a coupling component, several transmission shafts which each are rotatable about a transmission axis, a frictional contact ring including a friction cone and being substantially non-rotatably and axially shiftably connected with a transmission shaft, a form-fit ring including a cone surface and being substantially non-rotatably and axially shiftably connected with the coupling component, as well as an actuating body including a cone surface and being substantially non-rotatably and axially shiftably connected with the coupling component. The friction cone of the frictional contact ring extends between the cone surface of the form-fit ring and the cone surface of the actuating body. The transmission shaft and the coupling component are decoupled in direction of rotation in an axial starting position of the actuating body, frictionally coupled in direction of rotation in an axial frictional contact position of the actuating body and positively coupled in direction of rotation in an axial form-fit position of the actuating body. The form-fit ring in a form-fit position is positively connected with the transmission shaft and in a release position is not positively connected with the transmission shaft. The form-fit ring is axially movable between its form-fit position and its release position and is urged into the release position. In addition, a method for actuating a motor vehicle transmission is provided.

    摘要: A multi-plate clutch is disclosed, including an outer plate carrier, an inner plate carrier, and a set of plates of alternately arranged radially between the outer plate carrier and the inner plate carrier and which is delimited by two end plates engaging at opposite ends of the set of plates, wherein each end plate rests against an annular axial supporting contour on the end face facing away from the set of plates, wherein the supporting contours differ in their effective diameter at which the supporting contours contact the associated end plate, and wherein the supporting contours apply an axial force on the set of plates such that the plates are elastically deformed into a conical shape.

    摘要: A synchronizing device for a transmission has a sliding sleeve comprising an internal toothing with a plurality of sliding sleeve teeth and a clutch body of a gear wheel, comprising n external toothing with a plurality of clutch body teeth formed without meshing bevel at their axial tooth end close to the sliding teeth, into which the internal toothing of the sliding sleeve can engage. A synchronizing unit is provided which can block axial movement of the sliding sleeve, until the speeds of the sliding sleeve and clutch body are adapted. During operation, an axial force of the sliding sleeve against the clutch body is built up and a speed difference between the sliding sleeve and the clutch body is produced, so that the end faces of the sliding sleeve teeth and the clutch body teeth slide along each other, and the sliding sleeve teeth finally are meshed between the clutch body teeth.

There is provided a synchronizing unit which can block an axial movement of the sliding sleeve (112), wherein the clutch body teeth (120) are formed without meshing bevel at their axial tooth end (130) close to the sliding sleeve teeth (118). During the shifting operation the speeds of the sliding sleeve (112) and of the clutch body are adapted. There is built up an axial force (F) of the sliding sleeve against the clutch body and a speed difference between the sliding sleeve (112) and the clutch body is produced, so that the end faces (136, 134) of the sliding sleeve teeth (118) and the clutch body teeth (120) slide along each other, and the sliding sleeve teeth (118) finally are meshed between the clutch body teeth (120).
