Problems solved by technology

For example, in the patent literature (CN 105008729 A), an energy regeneration system for construction machinery is proposed, which uses a hybrid method to recycle the braking energy through a regeneration device composed of a hydraulic motor, an electric motor and a battery. The torque impact generated by the large inertial load is adjusted by setting the throttle valve before the energy recovery hydraulic motor. Although the stability of the braking process is improved, the throttling loss is increased, and this method requires multiple conversions to convert the energy. recycling, the efficiency is low

[0004] Analyzing the existing recycling methods, the disadvantage is that in the recycling process, in order to improve the controllability, throttling loss is unavoidable, and in the regeneration process, the energy conversion transmission chain is long and the loss is relatively large, so it is urgent to design a method for the existing Mechanical Engineering Equipment System for Recovery and Reuse of Loader Energy
