In order to improve the response speed and control accuracy of the power distribution device of new energy special vehicles,a new direct-acting valve-controlled power distribution device applied to new energy special vehicles was proposed.The solenoid valve spool was directly driven by the electro-mechanical converter with high power density,and the power distribution was realized through the combination and separation of the hydraulic control clutch.Compared with the traditional vehicle hydraulic control system,the pressure building time of the pilot valve is saved.Due to the reduction of first-stage hydraulic amplification,the nonlinearity of the system is reduced from the mechanism design,and the response speed and control accuracy of the power distribution device of new energy special vehicles are improved.The result shows that the clutch pressure of the device reaches 2 MPa in about 69 ms.
