Research on the Application of Double-action Vane-type Secondary Component in Vehicle Transmission System

The principle of double-action vane secondary component and its application was studied. The size and position of windows for oil discharge and entry are changed to achieve changes of flux and oil flowing direction. Under the variable pressure system, the energy saving theory of vehicle transmission system with application of the double-action vane-type secondary component was analyzed,the mathematical model of the bus hydrostatic transmission system has been set up, then the simulations of the performance of the transmission system has been conducted through the way which are adopted to reclaim the bus inertial energy by constant-power control. Simulation results show that the pressure of the system is not constant , and there is no energy transmitting between the secondary component and the vehicle engine. The inertial energy can be reclaimed and reused in the system by the application of the secondary regulation technology, and the power of the system can be reduced.
