Brake disc with friction ring and sheet metal holder

摘要

The brake disc has a sheet metal holder (6) which is dish-shaped and is positively coupled to the friction ring (1), whose inner edge section has inwards open recesses dividing the inner edge section into inwards protruding teeth (5). The outer edge section (10) of the holder is fitted with securing tongues (11) and with stops (12) alternating over the periphery. The radially outwards folded ends of the securing tongues engage positively the friction ring recesses, while the radially outwards bent ends of the stops grip round the friction ring teeth.
