Coil springs are widely used in independent suspensions, especially in front-wheel independent suspensions. However, in the rear suspension of some cars, the elastic elements also use coil springs. Compared with the leaf spring, the coil spring has the following advantages: no lubrication is required, and the longitudinal installation space required for the dirt is not large; the quality of the spring itself is small.
The coil spring itself has no damping effect, so a shock absorber must be installed in the coil spring suspension. In addition, the coil spring can only withstand vertical loads, so a guide mechanism must be installed to transmit various forces and moments other than the vertical force.
The coil spring is made of spring steel bar material and can be made into equal pitch or variable pitch. The former has a constant stiffness and the latter stiffness is variable.
The Auto Gas Springs is filled with a compressed gas in a sealed container, and the spring is acted upon by the compressibility of the gas. The stiffness of such a spring is variable because the amount of gas in the container is compressed as the load acting on the spring is increased, and the stiffness of the spring is increased, and the stiffness of the spring is increased. Conversely, when the load is reduced, the pressure inside the spring is increased. It has a lower stiffness and a lower stiffness, so it has an ideal variable stiffness characteristic.
Gas springs are available in both air springs and oil and gas springs. The air spring is divided into a capsule type and a membrane type. The oil and gas spring includes a single air chamber oil and gas spring, a double air chamber oil and gas spring, and a two-stage pressure type oil and gas spring.
