McPherson suspension and multi-link suspension, the pros and cons
Although according to grade and complexity of the suspension and the materials used to rank, multi-link is the best, followed by double-wishbone followed by McPherson, although the grade of this division.
In the three suspension McPherson is the most simple structure, and it is the lowest manufacturing cost of the most versatile. It is mainly used in the majority of small and medium-sized car on the bridge. It simple dominates. It is also because he simply so he light, fast response. And a lower rocker and pillar geometry can automatically adjust the wheel camber, let the road, so the tire contact area to maximize adaptive cornering, and a small footprint for small cars, and most of the mid-sized car to use. However, due to the simple structure so that the suspension stiffness is weak, poor stability, cornering roll obvious.
Double difference arm suspension with upper and lower rocker from the lateral force absorption by both rocker, the pillars carrying only body weight. Therefore, the lateral stiffness. As the use of unequal length rocker up and down (long and short), the wheel in the up and down movement can automatically change the camber and reduces tread changes to reduce tire wear. And adaptive road, the tire ground area, affixed to the good. However, due to more than one on the rocker, so the need to stand with larger space, the small car's front axle is generally arranged no less than such a suspension. The following code fragment:
Through a variety of link configuration (usually three-link and four-link, five-link suspension, multi-link), the first to achieve all the performance of the double-wishbone suspension, then on the basis of the double-wishbone link connecting shaft the binding effect of the tire in the vertical movement of the toe angle can also be changed accordingly, which means that the bend better adaptability, with front drive a front suspension, can to some extent alleviate the understeer, brings precise steering feel;, if used in the correct rear suspension, rear wheel toe angle change in the steering roll, which means that the rear wheels can to a certain extent with the front wheel with steering reach comfortable manipulation purposes. Like double-wishbone, multi-link suspension also needs to take up more space, and the multi-link suspension manufacturing costs and R & D costs are the highest so commonly used in senior car's rear axle.
On the whole, the most economical, the most cost-effective independent front suspension is McPherson, do high-performance tuning and matching multi-link double-wishbone suspension. The most complex structure to achieve maximum performance of multi-link. However, due to its quality after both structure heavier Therefore, in order to achieve a better response rate commonly used aluminum to create, then the cost can be imagined. more visite http://www.motor-
