Abstract
One or both end faces of the flange of the hub in a clutch disc have radially or nearly radially extending teeth which are caused to penetrate into adjacent shoulders of the sleeve-like other component of the hub so that the flange and the sleeve-like component are compelled to rotate as a unit. At least one of the shoulders is formed by upsetting the corresponding portion of the sleeve-like component.
Claims23
A composite structural element, particularly a hub for a clutch disc for use in a friction clutch of a motor vehicle, comprising an annular female component;
- a male component extending through said female component and having first and second shoulders flanking said female component to hold said components against axial movements relative to each other, said male component including at least one upset portion which defines one of said shoulders;
- and means for transmitting torque between said components, including protuberances provided on at least one of said components and extending substantially radially of said female component, and other of said componets having sockets for said protuberances, said sockets and said protuberances cooperating with said shoulders to rigidly connect said componets to each other and to hold said components against angular movement relative to each other and said sockets being defined by portions of said other component which are displaced by and disposed between said protuberances.
