Rear Suspension Cylinder Hydro-Pneumatic Spring Formining Dump Truck

Product Description

Product Description

The hydro-pneumatic suspension uses inert gas (nitrogen) as the elastic medium and oil as the force transmission medium, showing superior nonlinear elastic characteristics and good damping performance, which can meet the ride comfort requirements of engineering vehicles to the greatest extent.

Compared with other types of suspension, hydro-pneumatic suspension has significant advantages such as nonlinear stiffness, compact structure, and adjustable posture. It has a wide range of needs in Special vehicles, off-road vehicles, construction vehicles and construction machinery.

Our product advantages lies in:
• The suspension cylinder adopts imported sealing ring to meet the harsh working conditions of the mining area

• The suspension cylinder is designed to match the stiffness and damping characteristics according to the customer's vehicle parameters.

• The suspension cylinder is made of high-strength materials, and special heat meter treatment ensures that the suspension cylinder has a very high fatigue life under high-frequency, high-pressure and heavy-duty conditions.

• The piston accumulator is designed with two high and low pressure chambers to meet the empty and full load driving performance of the vehicle

• Steering cylinder have built-in displacement sensor, real-time monitoring cylinder stroke

• Can be customized according to customer needs design, provide integrated solutions

Machining Equipment 

Our company have 700 sets manufacturing equipment, such as cold drawing production line, heat treatment production line, surface treatment production line, testing equipment, various digital-control machining equipment, gantry style linear electroplating production line.
Every piece of hydraulic cylinder are processed through dozens of steps, including raw material processing, cylinder assembly, painting, etc. Each step is indispensable, and we also have advanced processing equipment to ensure that the processing dimensions of raw materials meet the requirements of product production.

Quality Inspection

Raw Material Inspection:The material of raw materials is detected by carbon and sulfur analyzers and spectrometers.
Material Performance Inspection:The tensile strength, yield strength, hardness and other properties of the material are tested by the material tensile test bench,Brinell hardness tester, Vickers hardness tester and other equipment.
Process Inspection:The geometric shape, shape and position tolerance and finish of semi-finished products are detected by three coordinates, profilometer and ultrasonic roughness meter.
Chrome Plating Control:The thickness, hardness and corrosion resistance of the product coating are tested by ultrasonic hardness tester, ultrasonic thickness gauge and salt spray test bench.
Every piece of hydraulic cylinder are tested and will send out only after they are pasted the each test. Our company has abundant technical force and perfect testing means. By making wide technical and business cooperation with many related enterprises, universities, colleges and institutes both at home and abroad, and employing senior engineers and software engineers, we have greatly strengthened and improved our designing, processing, and testing abilities.
