Double steering wheel electronic control system for electric forklift truck

Abstract

The invention discloses a double steering wheel electronic control system for an electric forklift truck, belonging to the technical field of new energy control of construction machinery. The double steering wheel electronic control system for an electric forklift truck comprises a main steering wheel, a sub-steering wheel, an electronic control unit, and a battery for supplying power to the electronic control unit, wherein the electronic control unit is connected with an angle sensor, a main steering wheel potentiometer, a sub steering wheel potentiometer and a display screen. The angle sensor is installed on the steering wheel of the electric forklift truck, the main steering wheel potentiometer is installed on the main steering wheel, and the auxiliary steering wheel potentiometer is installed on the auxiliary steering wheel. The sub-control unit is also connected with a solenoid valve which controls the steering cylinder connected to the electric forklift truck. The invention has good energy-saving performance: the steering system and the working device are separated, so that the operation efficiency can be improved and the energy consumption can be reduced; More ergonomic: Introducing directional potentiometers to steer for greater maneuverability and comfort.

Description

technical field [0001] The invention relates to a walking machinery control technology, in particular to a dual steering wheel electric control system for an electric forklift, belonging to the technical field of engineering machinery new energy control. Background technique [0002] Forklifts have been widely used in agricultural production and industrial construction around the world, and are indispensable construction machinery. Traditional internal combustion forklifts have gradually withdrawn from the market due to loud noise and serious pollution, and have been replaced by electric forklifts. Although the control technology of electric forklifts is becoming more and more mature, people put forward higher requirements for the operating comfort, energy saving and noise reduction of electric forklifts, and work efficiency. requirements. [0003] At present, the steering control of electric forklifts is still the traditional hydraulic steering wheel, which consumes a lot ...

AI Technical Summary

Problems solved by technology

[0003] At present, the steering control of electric forklifts is still the traditional hydraulic power steering wheel, which consumes a lot of energy and has poor comfort

Although various control methods are adopted to reduce system energy consumption and improve comfort, they still cannot fundamentally solve the problem. For example, using an auxiliary handle to control steering, the control is to control angular acceleration, that is, to control the speed of steering, which can be improved to a certain extent. Comfortable, but the control accuracy is not high, and the response speed is slow. At the same time, the troubleshooting only stops at prompting the fault, and cannot intelligently judge the type of fault, and the efficiency of troubleshooting is relatively low.
