Problems solved by technology

[0004] In the prior art, due to the low transmission efficiency of the hydraulic torque converter and the low combustion efficiency of the engine, the energy utilization rate of the loader is too low and the environmental pollution is serious.
Moreover, because the existing loader control cannot be decoupled and there is no closed-loop control, the hydraulic system overflows, and the hydraulic power provided cannot be effectively utilized

Abstract

The invention discloses an electric loader power control device and a control method thereof, and relates to the technical field of loading vehicles. The electric loader power control device comprisesa main controller, a first controller, a second controller and a third controller, wherein the first controller, the second controller and the third controller are respectively connected with the main controller through CAN buses. The first controller is connected with a walking motor and used for controlling the output power of the walking motor according to the control instruction of the main controller. The second controller is connected with a working motor and is used for controlling the output power of the working motor according to the control instruction of the main controller. The third controller is connected with a steering motor and is used for controlling the output power of the steering motor according to the control instruction of the main controller. Environmental pollution can be reduced, and the energy utilization rate during hydraulic control is increased.

Description

technical field [0001] The present invention relates to the technical field of loading vehicles, in particular to an electric loader power control device and a control method thereof. Background technique [0002] Loader is a kind of earthwork construction machinery widely used in highway, railway, construction, hydropower, port, mine and other construction projects. It is mainly used for shoveling bulk materials such as soil, sand, lime, coal, etc. , hard soil, etc. for light shoveling and digging operations. It can also carry out bulldozing, lifting and loading and unloading of other materials such as wood by changing different auxiliary working devices. Because fork-lift truck has operating speed fast, efficiency tall, maneuverability good, operation is light wait for an advantage, the main machine that accordingly it makes construction of the cubic metro of earth and stone in project is planted one of. [0003] With the general environmental trend of energy saving and ...
