Aluminum anti-roll bar is too soft?

In fact, many readers do not understand all the anti-roll bar actuation principle, let alone understand the anti-roll bar material differences between what different to the vehicle. In the vehicle suspension system, BMW Camber Plates the support vehicle and absorb the own weight, cushioning the impact surface is the greatest contributor to four shock absorbers, when the vehicle is in the course of steering, the vehicle will be transferred to the other side of the center of gravity of the steering, which condition will cause the side shock absorber compression force, while the other side is to reduce stress and tension, this situation will result in the case of the so-called roll, a roll condition reaches a limit but, for handling or comfort nature will be greatly reduced.

In order to reduce the vehicle is cornering roll over a big problem, if the shock absorber damping increase, spring bold, can indeed inhibit the degree of roll, but it will generate too much bounce, shock absorbers too hard problem, which not a good idea, and anti-roll bar is to solve this problem and the emergence of the chassis kit. Anti-roll bars are mostly made ​​of the same elastic spring steel, speak a little it is actually a white springs, coil-like shape not only under the general perception, but somewhat similar to the "mo" shaped structure. Anti-roll bar device will usually lower the tripod position, near I-beam or under the arm, crossbar section uses a rubber gasket and holder fixed to the vehicle, the ends are known through the "Li Tsai signed 'fixed symmetrical position shock absorbers or tripod foot, under the arm, etc., the principle is that by moving up and down as the displacement of the unilateral suspension system by anti-roll bars to withstand the stresses to disperse to the other side of the shock absorbers, this will not only be able to strengthen the capacity of the vehicle suspension system is also able to roll restraining enhance handling performance, so the market most of the vehicles are configured anti-roll bar this institution.

Most of the anti-roll bar of the material used, M3 camber arms and the spring are made ​​of the same high tensile alloy steel, this steel regardless of modulus of elasticity, tensile strength, yield strength (deformation restoring force) is quite excellent, and Manufacturing Technology mature, low manufacturing costs, and therefore long been used in the automobile manufacturing, such as the common coil springs, leaf springs, torsion bars, anti-roll bars, etc., but is not without its shortcomings, steel is the biggest Achilles Heel that the weight, the weight of the same volume of steel alloy material is aluminum or even titanium material at least three times or more, so a lot of the depot will be manufactured using advanced aluminum car bodies, and high-end aluminum alloy wheels are almost always the . However, in the part of the spring / anti-roll bar is why so few aluminum material it? In fact, not aluminum is not suitable for the manufacture of such products to the same size for the anti-roll bars, aluminum anti-roll bar tensile strength, yield strength are superior to steel, aluminum alloy speaking white point is less likely to deform damaged, but poor elasticity of aluminum alloys, such as steel of 22mm anti-roll bars, aluminum may want to 24mm-26mm in order to achieve the same elasticity, but the same elasticity anti-roll bars, aluminum products, only about weight steel alloys about half, for lightweight, but still quite an advantage.
