摘要：A drive arrangement (1) is disclosed where a driving gear (13) is engageable witha shaft (14) by engaging an axially movable sleeve (19) with a dog (23). One of the sleeve(19) or dog (23) is drivably connected to the gear (13) and the other to the shaft (14). Apiston (21) is engaged via fork (22) with the sleeve (19); axial movement of the piston (21)causes axial movement of the sleeve (19). A delay device is included which preventengagement between the sleeve (19) and dog (23) until the rotational speeds of thoseelements is equalised. The delay device include a friction plates (24) which create afriction drive between the driving force (e.g. gear (13)) and the element to be driven. Thefriction drive is actuated by actuator (25) under the same compressed air supply that actson piston (21). Torque acting between the friction plates (24) and sleeve (19) prevent thesleeve (19) from moving into engagement with the dog (23) before the speeds of thesleeve (19) and dog (23) have equalised.
