Average Spring Constant of Car Suspension
It is important that the proper wheel width be used for a given tire size. Drag race cars will normally use a lighter rate spring about 30 to promote weight transfer while a street car will use a firmer rate spring about 25. Vehicle Typical Damping Coefficient Download Table Inspect the rubber bushings on the track bars control arms strut rods sway bars and many more. . Once you have calculated all these take worst case scenario and assume that the entire card weight is on a single wheel. F k x. We will likely settle on a lower SF for the rear of the. This is because the energy input into the contact patch will be taken more by the suspension spring and less by the tyre. Example 500lbin 56 89K Spring Rate. To properly design a suspension for a cars weight aerodynamics and tires we often use suspension natural frequencies as a starting point for picking wheel rates and spring rates. So for a 8 kgmm spring y...
