AB - In order to solve the problems of high energy consumption, high noise and  pollution gas emission existing in the mechanical transmission system of  loader, a research on the mechanical transmission system of loader based on  hydraulic hybrid technology is proposed. The mechanical energy and heat  energy are generated by the mechanical operation of the loader, which are  converted into hydraulic energy and output to the drive system. According  to the fast response characteristics and high power density characteristics  of the hydraulic power system relative to the thermal engine, the dynamic  model of the hydraulic hybrid drive system of the loader is established. The  double fuzzy PID control method is used to identify and modify the unknown  load and power parameters of the drive system. Through the experiment, it  is concluded that the power parameter matching of the transmission system  using the hydraulic hybrid technology is more optimized, the application  effect is good, and the efficiency of the power transmission system can be  maximized.
