What kind of car suspension system, the advantages and disadvantages of the order of comparison
The following structural forms, McPherson, double A-arm (double-bar), trailing arm, torsion beam and multi-link. McPherson suspension for the front wheel, is a separate suspension, and is a very simple structure, compact layout, save space, front wheel positioning changes, with good driving stability. Therefore, most of the car before the suspension are used in this structure, the difference is mainly in the selection and shock absorbers, spring adjustment above. But the McPherson suspension in the use of shortcomings, that is, driving in the uneven road, the wheel is easy to automatically turn, so the driver must be forced to maintain the direction of the steering wheel, when subjected to severe impact, the shock absorber is easy to bend, thus affecting Steering performance, so many do not begrudge space and cost of luxury cars above and did not use this form. Double A arm hanging with two rocker from top to bottom, from the horizontal force by the two rocker at the same time absorption, pillars only carry body weight. So the lateral stiffness is large. As a result of the use of unequal long rocker (long short), so that the wheel in the up and down movement can automatically change the camber and reduce the track changes to reduce tire wear. And can also adapt to the road, tire ground area, good affixed. But because of the more on a rocker arm, so need to stand with a larger space, Honda's car before the suspension like to use this structure, Civic called the manipulation of the former, the front of the double arm A have some credit, sorry Is the 8th generation civic did not follow this structure, and the use of a lot of fans of McPherson regret.
Non-independent suspension, independent suspension, cross-arm suspension, multi-link suspension, longitudinal arm suspension, candle suspension, McPherson suspension, active suspension. Comfort and handling stability requirements are getting higher and higher, so non-independent suspension system has been gradually eliminated. The independent suspension system because of its good wheel touch, ride comfort and handling stability greatly improved, about two rounds of free movement, the freedom of the tire and the ground, the vehicle handling is better and other advantages are widely used by car manufacturers The Common stand-alone suspension system with multi-link suspension system, McPherson suspension system, trailing arm suspension system and so on.
Divided into separate suspension and non-independent suspension ~! Non-independent suspension is a rigid connection with a bar on both sides of the wheel, the impact of the side of the wheel, the vibration must affect the other side of the wheel, so naturally do not get better handling stability and comfort , While the wheels on both sides of the mutual influence, but also easy to affect the stability of the body in the steering time is more prone to rollover. Independent suspension chassis feel very obvious. As the use of independent suspension car on both sides of the wheels are independent of each other with the body connected, so from the use of the process, when the side of the wheel by the impact of vibration through the elastic element itself can absorb the impact force, this impact will not spread to another Side wheels, making the manufacturers at the beginning of the design of the model through the appropriate adjustment of the car ride comfort, stability, handling stability in three areas to obtain a reasonable configuration. Selection of independent suspension car in general, its handling and comfort are significantly better than the choice of non-independent suspension of the car.
In general, the car's front and rear suspension system includes spring and shock absorbers in two parts
