Abstract

The invention discloses a double-control integration valve. A two-position two-way mechanical-controlled valve and a two-position five-way air control valve are integrated effectively, an auxiliary box synchronizer is not out of gear during operation, an inverted T-shaped valve body is adopted, the two-position two-way mechanical-controlled valve and the two-position five-way air control valve are in an integrated structure, machining and production are facilitated, and cost is reduced. Channel distance between the air valves is shortened, and the auxiliary box synchronizer is prevented from being out of gear. The two-position two-way mechanical-controlled valve and the two-position five-way air control valve are replaced with the double-control integration valve, an air pipe between the two air valves is omitted, a connecting support of the two-position five-way air valve is omitted, cost is reduced greatly, assembling efficiency is improved, the auxiliary box synchronizer is not out of gear, and the whole integration valve is convenient to arrange, impact in structure and simple and has low cost, high assembling efficiency and reliability.

Description

technical field [0001] The invention relates to a double control integrated valve. Background technique [0002] For mechanical transmissions with main and auxiliary box structures, air valves and actuators (cylinders) must be used to realize the gear shift of the auxiliary box. At present, the air valve used in the main and auxiliary box structure transmission is a two-position five-way structure. According to the different gear positions, the air valve can be divided into mechanical control and pneumatic control. The existing main and auxiliary box structure transmission uses a two-position five-way mechanically controlled air valve, which has a simple structure, convenient layout and reliable performance. However, some transmissions with main and auxiliary box structures are affected by the control structure, and a two-position two-way mechanical control valve is added to the front end of the two-position five-way air valve, and a gas pipe is connected between the two va...
