Positive coupling for the transmission of torques between a shaft and a friction disc of a friction clutch

摘要

In a positive coupling between a shaft and a friction disc of a friction clutch, a radial slot in one half of the coupling, said half having an inner axial drive toothing, guides a sliding block in a manner which allows the said block to move radially and this sliding block is pressed by spring means against a corresponding outer axial drive toothing on the other half of the coupling.
