摘要
研究一种车辆用控制式差动齿轮式无级变速机的转速、效率、功率流以及转矩特性。结果表明，随iA变化，功率流、转矩在低速段变化很大。在此基础上进而探讨了模型试验机的齿轮疲劳强度核核计算点的确定问题，以及尖峰负荷下静强度校校的处理方法。最后指出实用设计时应按车型研究，
The article illustraes the roation speed, transmission defficiency, power flow and torqup properties of the differential gear variable - speed transmission for vehicles. In slower rotation. The power flow and torque change greatly with iA. based on which the calculation of gear endurance of the trial model transmission is determined. In design, the types of veces have to be taken into consideration.
