What is a hydraulic steering gear?
Hydraulic steering systems are devices that use hydraulic fluid pressure to assist the driver in turning the steering wheel, reducing the steering effort and improving the steering sensitivity. Hydraulic steering systems mainly consist of a hydraulic pump, a hydraulic cylinder, a hydraulic control valve, a reservoir tank and pipes. The hydraulic pump is driven by the engine and provides high-pressure fluid to the hydraulic cylinder. The hydraulic control valve controls the direction and flow of the fluid according to the direction and angle of the steering wheel, making the hydraulic cylinder generate corresponding thrust or pull force, helping the steering gear to push the steering wheel to deflect. The reservoir tank is used to store and replenish the fluid, and the pipes are used to connect the components.
Steering gear principle for small loaders and articulated forklifts
Loader(forklift) steering systems(Articulated four-wheel drive forklift) are a type of hydraulic device that controls the direction of travel of loaders, which are machines that load materials such as sand, gravel or soil onto trucks or other vehicles. They usually consist of a hydraulic pump, a hydraulic cylinder, a hydraulic control valve, a steering gear and pipes. Loader steering systems work by using the high-pressure fluid provided by the hydraulic pump, changing the direction and flow of the fluid through the hydraulic control valve, making the hydraulic cylinder generate thrust or pull force, driving the steering gear to push the front wheels or front frame to deflect, achieving the steering of the loader.
Articulated Steering Features
According to the structure of the steering gear, loader(forklift) steering systems can be divided into articulated, deflection wheel and skid types. Articulated steering systems connect the front and rear frames with a hinge pin, and steer by controlling the swing of the front frame. This type of steering system has the advantages of small turning radius and flexible maneuverability, suitable for narrow work sites. Deflection wheel steering systems steer by controlling the deflection angle of the front wheels. This type of steering system has the advantages of simple structure and easy maintenance, suitable for flat work sites. Skid steering systems steer by controlling the speed difference between the left and right drive wheels. This type of steering system has the advantages of compact structure and simple operation, suitable for wet and slippery work sites.
When choosing a loader(forklift) steering system, you should consider factors such as your work site conditions, your budget, your maintenance needs and your safety requirements. Different types of loader steering systems have different advantages and disadvantages, so you should choose the one that best suits your needs and preferences.
