Abstract

The invention discloses an elastic rubber band energy accumulator type loader movable arm potential energy recovery and regeneration control system which comprises a front axle frame, a movable arm, an elastic rubber band energy accumulator, a hydraulic electromagnetic reversing valve, a steel wire rope, a fixed pulley, a movable arm control rod lifting gear switch, a movable arm control rod descending gear switch, a movable arm lifting limiting switch and an electric control unit. The elastic rubber band energy accumulator type loader movable arm potential energy recovery and regeneration control system automatically recognizes operating intents of a driver to the movable arm of a working device of a loader and controls storage and release of elastic potential energy of an elastic rubber band so as to realize recovery, regeneration and utilization of the potential energy of the movable arm of the loader and realize energy conservation and emission reduction.

Description

technical field [0001] The invention relates to a potential energy recovery and regeneration control system for a loader arm, more precisely, an elastic rubber belt energy storage type loader arm potential energy recovery and regeneration control system. Background technique [0002] During the loading operation of the loader, the arm of the loader needs to be lifted and lowered frequently. During the lifting process of the arm, the engine drives the hydraulic pump to control the oil cylinder of the arm through the hydraulic reversing valve, and the arm together with the bucket and rocker Lift together to the unloading height. After the bucket is unloaded, the engine drives the hydraulic pump to control the boom cylinder through the hydraulic reversing valve, and lowers the boom, bucket and rocker to the loading height together. During the descent process, the engine is required to provide power, and the gravitational potential energy of the boom is wasted in vain, so that t...
