Study on Hydraulic System for Full Hybrid Transmission

Article Preview

Abstract:

Design method of hydraulic system of full hybrid transmission was analyzed. At first, oil volume flow and pressure requirement was confirmed according to the vehicle control strategy. Mechanical gear pump and electric pump were used to supply oil flow for all driving modes. Self-adapted pressure regulation circuit was designed to supply high pressure oil for brake engagement. Structure dimension of valves and cooling orifices was designed by theoretical calculation. Cooling flow can be distributed proportionally among electric motors and planetary gears.
