CONICAL DISK TYPE FLEXIBLE DRIVE MECHANISM

WIPO Patent Application WO2004010029

A3

A conical disk type flexible drive mechanism consisting of an input and output conical disk pair, containing a shaft, a single-piece or multi-piece fixed disk, a travel disk connected in a rotationally fixed and axially displaceable manner to the shaft, a support ring which is fixed to the shaft at a distance from the rear side of the travel disk such that it cannot be displaced axially, and at least one pressure chamber which is formed between the support ring and the rear side of the travel disk and which is provided with a hydraulic pressure medium by means of one or several ducts formed in the shaft leading into a peripheral surface of the shaft, whereby the pressure thereof can be modified in order to displace the travel disk. An end area of an inner surface of the travel disk guided on the shaft at a maximum distance from the fixed disk acts as an opening for the duct and ensures a hydraulic medium connection between the duct and the pressure chamber essentially by means of leakage gaps between the inner surface of the travel disk and the outer surface of the shaft.
