摘　　要：为提升新能源特种车辆动力分配装置的响应速度和控制精度,提出一种新型的应用于新能源特种车辆的直动阀控动力分配装置。该装置由高功率密度的电-机械转换器直接驱动电磁阀阀芯,通过液压控制离合器的结合与分离实现动力分配。相较于传统的车用液压控制系统,省去了先导阀建压时间;由于减少了一级液压放大,从机构设计上减少了系统的非线性度,提升了新能源特种车辆动力分配装置的响应速度与控制精度。结果表明:该装置离合器的压力达到2 MPa的时间约为69 ms。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.
