  • Drive system
    Patent number: 6431929
    Abstract: A drive system includes a drive shaft with first and second shaft sections connected by a diaphragm clutch having a diaphragm assembly. The radially outer end of the diaphragm assembly is connected to a disk having a first toothing arranged on one face of the disk. The first toothing engages in corresponding second toothing on a flange connected to the first shaft section when the diaphragm assembly is subjected to an axial preload. A contact-pressure device that is controllable by remote control in the stationary condition acts against the disk to produce the preload.
