Accumulator Circuit Used in Hydraulic Hybrid Vehicle

设计了一种用于液驱混合动力车辆的蓄能器储能回路,搭建了试验台架,完成了蓄能器充压、保压试验,得出了系统配置参数对蓄能器充能效果的影响规律。试验结果表明:所设计的回路满足设计需求,电机转速1 000 r/min时,回路综合性能较好,变量泵排量范围34～46 cm^3/rev。

An energy storage circuit of accumulator for hydraulic hybrid vehicle was designed. The test bench was built. The pressure-filling and pressure-holding test of accumulator was completed, and the influence of the system configuration parameters on the energy-charging effect of the accumulator was obtained. The test results show that the designed circuit can meet the design demand, the overall performance of the circuit is better when the motor speed is 1 000 r/min, and the range of pump displacement is 34~46 cm 3/rev.
