  • Synchronizer clutch for a motor vehicle multistep transmission
    Patent number: 7445103
    Abstract: A synchronizer clutch for a motor vehicle multistep transmission, having a guide sleeve which is fixedly arranged on a shaft, and a synchronizer ring which is mounted so as to be moveable relative to the guide sleeve. The guide sleeve has an axial contact face which an axial face of the synchronizer ring can abut against when the latter is in a rest position. At least one of the axial contact face and the axial face has at least one depression which is not significant in terms of the general function of the synchronizer clutch, but reduces the contact area between the axial contact face and the axial face in the rest position. Thus, when the synchronizer ring moves axially away from the guide sleeve, there is essentially no adhesion on account of lubricating oil.
