Embodiment Construction

[0013] Such as figure 1 As shown, the steering controller collects signals such as the steering mode switch in the cab, the frame inclination sensor, the boom length and luffing angle sensor, the boom luffing pressure sensor, the vehicle speed sensor, the fork system inclination sensor and other signals, and receives them through bus communication For information such as engine speed, the controller controls the action of the corresponding steering valve through internal logic operations, and controls the engine speed through bus commands, and can display fault alarms and other information through the display.

[0014] Forklift steering control logic methods such as figure 2 Shown. After the forklift is powered on, the controller obtains the steering mode switch signal in the cab to determine whether to switch the steering mode. If the steering mode is switched, the forklift speed signal is collected to determine whether the forklift is in a stationary state. If it is not in a s...

Abstract

The invention discloses a forklift steering control device and method. The control device comprises a steering controller, a steering mode switch connected with the steering controller and mounted in a cab, a forklift frame inclination sensor mounted on a forklift frame, an arm rest length and amplitude-change angle sensor, an arm rest amplitude-change pressure sensor, forklift speed sensors mounted on a front wheel and a rear wheel of a forklift, forklift wheel steering angle sensors mounted on the front wheel and the rear wheel of the forklift, a pallet fork system inclination sensor and a steering valve. According to the forklift steering control device and method, forklift steering modes can be switched, the safety is high, and the manual misoperation risks are greatly reduced; when the forklift drives with cargos, safety control such as engine speed limiting is conducted according to cargo moment, and the safety of cargo carrying driving is improved; and the purpose of rapid and safe forklift steering is achieved.

Description

Technical field [0001] The invention relates to a forklift steering control device and a control method. Background technique [0002] Forklift steering system is an important system that affects the stability and safety of forklift handling. The forklift steering system plays an important role in ensuring the safe driving of the forklift and protecting the working conditions of the driver's personal safety. At the same time, due to the requirements of production and technological innovation, people’s requirements for forklifts are becoming higher and higher. In order to enable forklifts to turn in smaller places, they require a small turning radius to meet the requirements of different working conditions and achieve a variety of Steering control mode. [0003] Forklift steering system operation and mode switching are unreasonable, it is easy to steer wrong, which affects the normal driving of the forklift, such as aggravating the friction between the tire and the ground, or caus...
