Abstract
The utility model discloses a speed changing box back power-taking control system with a gear locking mechanism. The speed changing box back power-taking control system comprises a parking power-taking control switch, a power supply, a magnetic type two-position four-way valve, a two-position three-way valve with a valve rod, an operating assembly and a gear-engaging cylinder assembly. When the parking power-taking control switch is in a switched-on state, a combined piston of the gear-engaging cylinder assembly moves towards the left and stops at the partition plate position under the air pressure effect. A piston of the gear-engaging cylinder assembly moves towards the right, is blocked by the combined piston and stops at the middle neutral gear position, and gear engagement of an auxiliary box is not in place. A gear locking piston pin quits from a gear locking groove of a gear locking control block of the operating assembly under the effect of spring force, a transverse gear shifting rod can freely rotate to achieve gear engagement. When parking and power taking are not needed, the gear locking mechanism can protect a speed changing box. When the parking and power taking are needed, the gear locking mechanism does not influence a parking power-taking function of a back power-taking device. An existing gear locking mechanism and an auxiliary box forced neutral-gear engaging system are effectively integrated through the magnetic type two-position four-way valve, system parts are few, and the cost is low.
