Synchroniser clutch for gearbox - has tapered friction ring and tapered sleeve extending from shaft gear

摘要

A gearbox (6) includes a synchronizing coupling (1) with a tapered friction ring (8) that encloses a ring chamber (10). The coupling friction ring (8)9 is located inside a tapered sleeve (9) which extends axially from the shaft gear (18). Radial holes (11) in the tapered sleeve, axially offset from the friction ring location provide lubrication oil transfer from the gear box space (5) into the ring chamber (10). ADVANTAGE - Tapered friction ring on synchronizing coupling in gearbox, is provided with improved lubrication oil supply.
