High Quality Truck Suspension Parts Shock Absorbers Air Suspension Springs for MAN 81417226075 8147226003

Load-bearing Capacity: According to the design load range of MAN models, the shock absorber air suspension spring should have sufficient load-bearing capacity to safely and stably support the weight of the fully loaded truck cab and cargo. Generally, the load-bearing range needs to reach several tons to dozens of tons. And within the rated load-bearing range, ensure that there is no permanent deformation or damage to the structure and maintain stable elasticity and shock absorption performance.
Stroke Range: Design a reasonable compression and extension stroke to meet the relative displacement needs between the cab and the frame of the truck during driving, such as when passing over uneven roads, speed bumps, and potholes. Generally, the stroke is between several tens of millimeters and several hundred millimeters. It can not only provide sufficient buffer space but also avoid shock absorber failure or component collision damage caused by excessive or insufficient stroke.
Stiffness Characteristics: Present a nonlinear stiffness change curve. Maintain a low stiffness when lightly loaded to ensure good driving comfort and filter out small vibrations. As the load increases, the stiffness gradually increases to ensure the driving stability and maneuverability of the vehicle under heavy loads and harsh road conditions, effectively preventing excessive sinking or shaking of the cab and maintaining the overall balance of the vehicle's posture.
Damping Characteristics: Can generate accurate and appropriate damping forces in both compression and extension strokes. The damping force in the compression stroke is moderate, which can effectively buffer impact energy and avoid rigid collisions. The damping force in the extension stroke is stronger, which can quickly attenuate vibrations, prevent rebound and aftershock phenomena, and make the vehicle drive smoothly. Moreover, the damping force can be intelligently adjusted according to factors such as vehicle speed, road conditions, and driving modes to optimize the shock absorption effect.
