MECHANICAL TRANSMISSION SYSTEM OF LOADER BASED ON HYDRAULIC HYBRID TECHNOLOGY

ABSTRACT
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.
