Abstract

The invention relates to the research design field of the balance of a fork lift truck, in particular to an electronic control system for a balance control system of a four-wheel counter balanced fork lift truck. The system comprises a processing module and a power driving module, wherein the processing module is used for receiving signals sent from a throttle sensor, a brake pedal position sensor, an oil pressure sensor of a total system oil passage, a gyroscope sensor, a steering wheel angle sensor, an engine speed sensor, a vehicle speed sensor, a braking oil pressure sensor of four wheels, and a wheel speed sensor of the four wheels. After the signals are processed, control signals are output to the power driving module. The power driving module is used for outputting driving electric energy to drive the balance control system of the fork lift truck to act. By the collection and the processing of the signals of the sensors, the accurate control of the balance control system of the fork lift truck is realized, the controllability of the fork lift truck is improved, the possibility of the tipping generated by the ascending, descending, speeding, braking and steering for the fork lift truck is reduced, and the driving safety of the fork lift truck is furthest ensured.

Description

technical field [0001] The invention relates to the field of forklift balance research and design, in particular to an electric control system for a balance control system of a four-wheel counterweight forklift. Background technique [0002] Due to its compact body, flexible steering, various types and models, and high site adaptability, forklifts are more and more widely used in the field of logistics, and the handling and loading and unloading of goods are basically completed by forklifts. Except for a few types of special-purpose forklifts or special forklifts, most forklifts adopt a four-wheel counterweight layout in the design of the whole vehicle, that is, in the forward direction of the forklift, the front of the fork frame is arranged, and the whole vehicle is supported by four wheels. Cargo Weight, Front Wheel Drive, Rear Wheel Steering. Four-wheel counterbalanced forklifts generally use mechanical steering or hydraulically assisted power steering in steering opera...
