Abstract

1,000,494. Positive clutches. FIAT S.p.A. Jan. 7, 1964 [Jan. 12, 1963], No. 693/64. Heading F2C. An internally coned balk ring 8, having the usual chamfered teeth 9 for preventing asynchronous engagement between an internally toothed axially slidable clutch sleeve 6, splined on a shaft hub 1, and clutch teeth 11 on a freely mounted gear-wheel 12 in a motor vehicle change-speed gear, is permanently loaded into frictional engagement with the complementary cone of the wheel 12 by axially projecting tongues 14 of a spring ring 13 arranged between the balk ring 8 and shaft hub 1, with respect to which latter the balk ring 8 has circumferential play limited by projections 15 on the ring engaging recesses 4 in the hub.
