A gas spring consists of a sealed cylinder filled with a charge of high-pressure [5] gas, a piston rod attached to a piston with a sliding seal, and some oil. [1] The piston (or the cylinder wall) contains a number of channels that allow the gas to transfer between the lower chamber (between the piston and the closed end of the cylinder) and the upper chamber (between the piston and the head ...
The spring rate (or suspension rate) is a component in setting the vehicle's ride height or its location in the suspension stroke. When a spring is compressed or stretched, the force it exerts, is proportional to its change in length. The spring rate or spring constant of a spring is the change in the force it exerts, divided by the change in ...
Torsion bar suspension inside Leopard 2 Schematic of a front axle highlighted to show torsion bar. A torsion bar suspension, also known as a torsion spring suspension, is any vehicle suspension that uses a torsion bar as its main weight-bearing spring. One end of a long metal bar is attached firmly to the vehicle chassis; the opposite end ...
The longer spring allows for more controlled flexion and potentially longer throw. Christie suspensions are generally more difficult to maintain because the wheels and suspension are mounted separately, and a broken spring can be difficult to reach without removing the wheels.
In addition to spring type (multi-leaf steel, FRP), a distinction can be drawn between systems where the spring also acts as a locating link and those where the spring only acts as a spring member. The AC Cobra is an example of a transverse, multi-leaf steel spring suspension that uses the leaf spring as the upper suspension arm.
Very early cars had a design flaw in their front suspension which caused dangerous handling. While it was corrected before full-scale sales began, the Marina was still criticized for its poor handling, road holding, and refinement. The Daily Telegraph included the Marina on its list of "10 Cars That Should Have Never Been Produced". [52]

The MacPherson strut is a type of automotive suspension system that uses the top of a telescopic damper as the upper steering pivot. It is widely used in the front suspension of modern vehicles.
Automotive suspension design is an aspect of automotive engineering, concerned with designing the suspension for cars and trucks. Suspension design for other vehicles is similar, though the process may not be as well established. The process entails Selecting appropriate vehicle level targets; Selecting a system architecture
