<p>Locking mechanism for releasably locking a component, eg a road wheel axle, on a vehicle in a desired position comprises means (23, 21) for moving the component, or allowing it to move, to that position, a latch member (31) on the component and a locking member (33) movable into and cut of operative engagement with the latch member by an air operated actuator (28) to retain the component in, and release it from, the position. One application of the mechanism is to hold in a raised in -operative position a suspended axle (16) of a freight carrying road trailer adapted for rail travel. The latch member (31) and actuator (28) are mounted on the axle (16) which is raised to the in-operative position by an air bag (23). The actuator (28) pivots a brake lever (26), also on the axle, into ergagement with a pivoted arm (34) of the locking member (33) which pivots a hook (36) of an associated arm (35) towards engagement with the latch member (31) to hold the axle raised when the air bag (23) is de-pressurised. <IMAGE></p> |
