摘　　要：针对传统电动汽车动力形式单一带来的缺陷,提出机电液动力耦合电动汽车的工作原理,利用机电液耦合器实现电能、机械能和液压能的任意相互转化,克服了传统电动汽车的诸多弊端。阐述机电液动力耦合电动汽车动力传动的5种基本模式。建立了机电液动力耦合电动汽车的机械、电、液压动力匹配的数学模型。基于CLTC工况,利用AMESim与Simulink联合仿真了机电液动力耦合电动汽车跟随性、电动力、储能器压力、耗电量等特性参数,验证了机电液动力耦合电动汽车动力传动原理的可行性。In view of the defects brought by the single power form of traditional electric vehicle, the working principle of electro-mechanical-hydraulic power-coupled electric vehicle was proposed, in which electromechanical-hydraulic coupling was used to realize the arbitrary mutual transformation of electrical energy, mechanical energy and hydraulic energy, overcoming many disadvantages of traditional electric vehicles.The five basic modes of the power transmission of electro-mechanical-hydraulic power-coupled electric vehicles were described.A mathematical model of the mechanical, electrical and hydraulic power matching of the electro-mechanical-hydraulic power coupled electric vehicle was established.Based on the CLTC operating conditions, AMESim and Simulink were used to jointly simulate the characteristics parameters of the electro-mechanical-hydraulic power coupled electric vehicle such as following, electric power, energy storage pressure and power consumption.The feasibility of the electro-mechanical-hydraulic power coupled electric vehicle power transmission principle is verified.
