Locking device to prevent engagement of reverse gear in gearbox - uses locking pin actuated by centrifugal force

摘要

Locking device within a vehicle gearbox for preventing the engagement of reverse gear during travel in a forward gear in which a locking pin (31) actuatable by centrifugal force against a spring (33) is arranged axially between two synchronisation rings (27 28) and radially between the gear sleeve carrier (24) and the gear sleeve (25). The gear sleeve carrier has a radially arranged bush (29) in which the locking pin is radially movable outwards the against the resistance of the spring. ADVANTAGE - Compact design for a gear box locking device with few individual parts.
