Abstract: This paper focuses on the definition, structure, working principle, advantages and disadvantages of the split type solenoid valve. Combined with the split type solenoid valve products on the market and the demand characteristics of automatic transmission, through theoretical calculation, simulation analysis and optimization, test verification, consistency influence factor analysis, a high precision split type solenoid valve suitable for wet dual clutch automatic transmission is designed. And in the design process to form a complete split type solenoid valve design theory and method, at the same time in the split type solenoid valve hydraulic module application and cost reduction to achieve a great breakthrough, for the design of the solenoid valve laid the foundation.
