Abstract

The invention discloses a drive control system for a pure electric loader and belongs to the technical field of shoveling-transferring engineering mechanical vehicles. A traveling system is connectedto the lower side of a machine body. The machine body is provided with a hydraulic system and further provided with a hydraulic motor and a traveling motor. The hydraulic motor is connected with a hydraulic pump. The hydraulic pump supplies power to the hydraulic system. The traveling motor is connected with a traveling system through a transmission system. The transmission system comprises a fully-automatic speed changing box connected with the hydraulic motor. The output end of the fully-automatic speed changing box is connected with a transfer case. The transfer case is connected with the traveling system and supplies power to the traveling system. According to the drive control system, the traveling system is driven by the traveling motor, and the hydraulic system is driven by the hydraulic motor; compared with mechanical transmission adopted in the prior art, the traveling system is high in transmission efficiency, electrodeless speed changing can be achieved, and gear shifting isachieved easily; the power is great; the hydraulic system can provide stable and efficient powerful driving force; the drive control system is great in universality and convenient to maintain; and defects of an existing loader are overcome.

Description

technical field [0001] The invention relates to a pure electric loader technology, in particular to a driving control system applied to a pure electric loader, and belongs to the technical field of shoveling construction machinery vehicles. Background technique [0002] Loaders are used for loading, unloading, pushing, construction and other operations of bulk materials such as soil, gravel, coal, etc., and are widely used in various construction sites. Loaders in the prior art are divided into fuel-driven loaders and natural gas loaders. Fuel-fuel loaders are powered by an internal combustion engine such as a diesel engine, and natural gas loaders are powered by a gas-burning engine. At present, a large number of wheel loader transmission systems use internal combustion engine power, and the transmission device is hydraulic transmission, which is mainly composed of engine, torque converter, power shift transmission, transmission shaft, drive axle and so on. The power trans...
