Why do air springs have better shock absorption than steel plates?
1. Comfort. Leaf spring independent suspension, heavy weight, large
stiffness, poor comfort, long longitudinal size, is not conducive
to shortening the car's front suspension and rear suspension, and
the connection of the leaf spring pin is easy to wear and so on.
2. Security. For multi-axle vehicles, air suspension ensures that
the load between each axle is uniform, which avoids the whole load
of single bearing in leaf spring suspension. For a single axle, air
suspension basically ensures that the forces on both sides of the
vehicle's wheels are evenly distributed. Air spring suspension can
make the tire and the ground as far as possible to maintain pure
rolling contact, basic can achieve the best braking effect.
Therefore, air spring suspension is safer than leaf spring
suspension.
3. Reliability. The parts and components of air spring suspension
have accepted the rigorous fatigue test of foreign laboratories and
the reliability test in harsh environment, and have been verified
by the real car operation of our customers for many years. The use
of air spring can improve the reliability of the chassis and body
electrical system, overcome the rigid contact and friction, not
only ease the impact between parts and greatly improve the
reliability of the system. It can be seen that air spring
suspension than leaf spring suspension del higher reliability.
