Energy-saving Potential and Influencing Factors for Hydraulic Hybrid Wheel Loader

Abstract:

According to the operating characteristics of wheel loaders, the energy distribution and saving potential of loader were researched through calculation and simulation. Combing the characteristics of hydraulic hybrid system, the parallel configuration of hydraulic hybrid wheel loader was presented, and the influencing factors for hydraulic hybrid wheel loader energysaving potential were analyzed. Finally, the key parameters were optimized. The results show that optimization of hydraulic hybrid power system, selection of the appropriate parameters in control strategy, recovering the braking energy and long slope potential energy of loaders are helpful to improve the energy saving effect of hydraulic hybrid loader.
