A power shift control valve
By designing a combination structure of micro-motion valve core and micro-motion valve stem for the power shift control valve, automatic adjustment is achieved by utilizing the difference in spring force. This solves the problems of poor low-speed control smoothness and high operation difficulty of traditional power shift control valves under different ground conditions, improves the system's anti-pollution capability, and reduces costs.

AI Technical Summary
Traditional power shift control valves have poor low-speed control smoothness under different ground conditions, and long-term operation of half-clutch control is difficult. Mechanical control relies on driver experience, while electronic control systems are expensive and have poor pollution resistance.
A power shift control valve was designed. Through the combination structure of micro valve core and micro valve rod, and by utilizing the different elastic force relationship between balance spring and pressure regulating spring, the micro valve core can be automatically adjusted to automatically switch the semi-clutch state according to the oil pressure, thereby reducing the difficulty of operation.
It improves the smoothness of low-speed control of vehicles under different ground conditions, reduces the difficulty of operating the half-clutch control in gear for a long time, reduces the dependence on driver experience, reduces manufacturing costs, and improves the system's resistance to pollution.
