1、 附 录 外文翻译 McPherson model of the independent suspension McPherson front suspension in the car on the other is the breadth of application of the hoisting second to none. To the big BMW M3, Porsche 911 such high-performance cars, small Fiat STILO, Ford FOCUS, even before Chinas Hafei van Maifuxunshi h

2、oisting and are based on the design. What is the reason in the end allow the hoisting of the McPherson such wide application This so commonly used hoisted in the end what characteristics it We start with the design of structural understanding from the bar. Diagram below is a typical example of the h

3、oisting of the McPherson Construction of the -1: Figure -1 McPherson hoisted chart McPherson usually hoisted by two basic components: A pillar of shock absorbers and fonts care arm. The reason is because it is the pillar of shock absorber damping is also available in addition to supporting the role

4、of the whole body, his structure is compact, the shock absorber damping and spring together to form a movement from top to bottom can slip column； under A boom is usually entrusted the design fonts, for the wheels to provide some of the lateral support and direction to bear all the stress before and

5、 after. The weight of the entire body and vehicle movement to bear all the wheels on the impact of these two components * commitment. So McPherson one of the greatest features of the design is simple, simple structure will bring direct benefits of the two that is: the hoisting of light weight and sm

6、all space. We know that the car belongs to the hoisting of moving parts, moving parts the light, then hoisted response rate of speed and resilience will be sooner, so the hoisting of the shock absorption capacity of more strong and reduce the quality of the hoisting of spring also means reducing the

7、 quality, then in Body weight certain circumstances, the comfort is also better. Space on the direct benefits of the designer is in store layout engine under greater engine and the engine can be placed arbitrary manner. In medium-sized car engine can be put aside large, small car in the medium can a

8、lso lay down their engines, so that all the matching engine more flexible. We allKnow, the BMW inline six-cylinder engine is designed, in the pursuit of sport, the layout of its center of gravity in the front axle, so the engine to use up a lot of warehouse space of the engine, then the choice of a

9、simple structure, the hoisting of the small space It is by design is important. McPherson suspended from the upward journey, that is, in the event to roll, wheel angle, will automatically increase, so that tires can better integrate with the road, the vehicle to provide greater lateral force, to imp

10、rove the Control limit. Have excellent control and responsiveness coupled with the tight structure, it is clear on a BMW designers before hoisting the preferred option. For small cars and mini-cars, as far as possible in a small engine stores make room layout engine becomes even more important, so t

11、hey have no choice but to select McPherson hoisted Moreover, if a reasonable match, McPherson Whether manipulation and comfort are very good. That so much has been hoisted at the merits of McPherson, the talk about the shortcomings. It is also precisely because McPherson is too simple structure, cau

12、sing the hoisting of the stiffness limited. As McPherson hoisted only * care arm and shock absorber to withstand a strong pillar of the wheel impact, it is easier in geometry deformation. This deformation of the driving experience, is that motorists will obviously feel the stability of poor body. Wh

13、ether turning roll or brake nod phenomenon, are very obvious. Of course, the designers also like a lot of ways to solve the problem of instability. We have often heard that the horizontal Wending Gan, the anti-roll bars, balance, etc.-are used to increase the hoisting of Mai Fus geometric stiffness

14、and lateral stability of the components. However,WenDinggan optical increase by improving the performance is limited,the use of Wending Gan design can improve the stability of certain extent,geometry and suspension stiffness. If in order to fundamentally solve these problems, we must change the hois

15、ting of the geometric shapes, and then multi-link double-rocker hoisted on behalf of the hoisting of a high-performance. McPherson addition to the hoisting of stability and rigidity in regard to inferior to multi-link, on the durability and multi-link can not be hoisted at par. As McPherson hoisted pillars need to bear the shock absorber of the horizontal, from top to bottom at the same time a campaign to reduce the purpose of vibration, shock absorber supporting bar the friction is very uneven, shock absorber oil seal to wear a hydraulic oil Damping effect of reducing leakage.
