为提高履带车辆电传动系统电机功率在全行驶工况的利用程度,降低电机功率,分析了履带车辆双侧独立电传动方案的优缺点,按照行星传动连接关系提出了可实现履带车辆转向功率机械回流的六种电传动方案。建立了这些方案的运动学、动力学数学模型,并进行了运动学、动力学及部件功率需求特性仿真分析,绘制了不同转向工况下的功率流图,并分析了各种方案的可行性。提出的行星差速机构可以有效地降低履带车辆对电机的功率需求。采用齿圈和行星架两种连接方式的差速机构方案是可以满足系统要求的。研究成果对履带车辆电传动的方案选择有一定的启发和指导作用。
In order to improve the utilization of motor power of electric drive system of tracked vehicle under all driving conditions and reduce the motor power, the advantages and disadvantages of two independent electric drive schemes of tracked vehicles are analyzed. According to the planetary transmission connection, Six kinds of electric drive back to the program. The kinematics and dynamics mathematical models of these schemes are established, and the kinematics, dynamics and power demand characteristics of the components are simulated and analyzed. The power flow charts are drawn under different steering conditions and the feasibility of various schemes is analyzed . The proposed planetary differential mechanism can effectively reduce the power requirement of the crawler vehicle to the motor. The use of gear and planet carrier connection of two differential mechanism program is to meet the system requirements. The research results have a certain inspiration and guidance for the choice of electric drive of tracked vehicles.
