Knowledge about air spring
1, the origin of air spring
Not long after cars were invented, when comfort was very poor, inventors wanted to use this property of air to make air springs for cars. The aim is to improve the comfort of the car through shock absorption. Early attempts, due to manufacturing technology and raw material problems, did not achieve the durability of these early air springs. In 1901, William W. Humphreys, an American, patented his design for a cushioning air cushion that would reduce the vibrations transmitted to the cabin, but the suspension was still a metal spring. Messier, a Frenchman, designed the earliest automobile air springs in the 1920s, and in 1929 the Czechoslovakian TATRA automobile Company experimented with installing air springs on the rear axle of its T24 truck.
It was not until 1946, after the end of World War II, that the StoutStout Scarab, designed by American inventor William Bushnell, was equipped with an air spring designed and manufactured by Firestone. It was the world's first car with an all-air spring suspension.
2, the role of air spring
The main air spring is: 1, shock absorption. 2. Comfort. 3. Adjust the height according to specific requirements. Compared with the ordinary metal spring with fixed elastic damping coefficient, the elastic coefficient of air spring not only has the characteristics of adaptive adjustment of damping, but also solves many small vibrations on the road surface, so the improvement of vehicle riding comfort is self-evident. Air because of the shock absorber air bag in the air spring can reduce the vibration transmitted to the cabin, so when the wheels bump on the road, the body and seat hardly vibrate, so as to improve the vehicle ride.
3, why to install the air spring?
1) Improve the comfort of car driving
2) The balance of car shock absorption, the applicable life of the car can be extended
3) Achieve the balance of multi-bridge axle load and braking force
