Snow Folan Mai Rui Bao suspension interpretation

Mai Po sharp front suspension with McPherson independent structure, with excellent steering response, the driver provides excellent handling performance. The four-link rear suspension independent structure to ensure that the manipulation comparable limousine ride comfort. In addition, the Mai Po sharp whole system comes standard with speed booster after a special adjust the rack and pinion EPS electronic steering mechanism, large-size four-wheel disc brake system, high-quality material bushing and numerous aluminum alloy lightweight parts, vehicle driving and riding performance to new heights.

Mai Po sharp front suspension with McPherson independent structure, the structure is more common, but the chassis on the details of the deal would still show a generic European R & D center tuning skill.
In order to achieve the the unsprung best quality and vehicle before and after the mass ratio, the Mai Po sharp before the suspension using a large number of lightweight materials such as: aluminum alloy knuckle and lower control arms, in unprecedented stabilizer bar, lightweight polymer 18% decline in the overall quality of material before the stabilizer bar connecting rod, front suspension, lighter weight to achieve the maximum level of security, enhance vehicle dynamics control sensitivity.
In addition to reducing quality, to achieve the same level of the leading driving feel, Mai Po sharp use of "full-frame" subframe common in luxury cars. Full box closed shaped subframe structure like chassis frame, compared to the traditional "ingot beam," with better structural rigidity, thereby enhancing the body longitudinal, lateral rigidity and vehicle torsional rigidity, stable performance dramatically limit state The real heavy, calm driving experience. In addition, the Mai Po sharp front shock absorber buffer block optimization, lengthened design make suspension to keep the initial stage of soft and comfortable at the same time, has better support for the performance of the rear section, may be losing the day-to-day riding comfort at the same time, improve the ability to control body posture, inhibit substantial body roll under the steering. Mai Po sharp front stabilizer bar, bold design, diameter 26.4mm thick front stabilizer bar greatly improve the vehicle into the corners and ultimate stability.
Improve the Mai Po sharp ride comfort, the engineers also spent a lot of effort. Chassis vibration and noise are two main factors affecting ride comfort. Mai Po sharp front suspension control arm and subframe connections using aluminum hydraulic bush - a more luxury car connection. Hydraulic bushing to bring better suppression earthquake passengers, noise reduction, high-speed 100-120km / h driving time, can significantly reduce the annoying steering wheel jitter. Mai Po sharp front shock absorber hidden mystery, shock absorber top of pillar bushing dual channel, passed to the spring and shock absorber load independent body, provides better shock absorption effect; compared with the lower part of the shock absorber level models, increase the one MCU polyurethane polymer isolation pads to further enhance the chassis vibration filtering capabilities.

Fit to participate in the Pan-PRD race modified multi-link rear suspension

Guangzhou Honda Fit original suspension is torsion beam type, this suspension there making maintenance simple, low cost and by all economic models favored. But it also has a non-independent suspension innate shortcomings, when changes in the side of the wheel movement (encounter bump) will affect the other side, the rear-wheel angle available for tuning, special occasions (such as racing), often flexibility in turning the above disadvantage. So, Guangzhou KY Racing Serene produces a modified rear suspension ideas to improve steering performance, is here to create the best lap decisive.

Relying on such a picture guess the car, I was able to may not be correct to say.

First, they found a length Fit body width is almost the same sub-frame, the rear suspension of most of the rod member wherein the one articulation point is mounted on the subframe, since the role of a bridge between the suspension rods and the body things, but the fixing of this "bridge" is itself a very test the knowledge of the person, the hand level of processing technology, it is estimated that in this process the shape of the sub-frame has been modified, its four fixing points can be "posted" body convenient tapping next to the body.

With this basis of the above, then we must determine the position after claw. From the current shape of the shock machine guess the Serene is shock machine to accommodate croissants, so it was welded on an adapter seat. Similarly accommodate the claw under vertical putter, it is also an adapter. Eventually, two transverse links, a vertical putter, a shock absorber unit became Fit rear suspension. From a formal point of view, this is the multi-link suspension, so that, including the tilt angle of the rear wheels, the beam angle adjustable function etc., an introvert rear wheel tires can help in the corners for more touchdown area, increase the centripetal force, under the premise of the other conditions remain unchanged, cornering speed can be raised even higher, out of the corners, the greater the initial velocity, which decide the outcome.

Before, Fit to create 1:58 the fastest lap with a Track Day tires. Now, after flying the dual role of qualitative change + slicks, and stood the ideal theoretical angle Fit is expected to move forward about 4 seconds, which is a comparable Honda Integra type cells (DC) results. Of course, this is just a nice wish, even the master of Serene not guarantee what the strength of how the outcome this weekend!

The rear sub-frames plays a role of a bridge connected to the suspension rods and the body, the suspension can be seen from this figure there is a plurality of angles can be adjusted.

  

The frame structure crude solution

Before two of the most basic and simple frame body, this paper introduces a more complex integration space frame and tube Zhenshi frame.

The integration-frame:

1, the traditional integrated frame

The two no branched structure frame in the form introduced after the remainder of the two forms has a branched structure. The first is the integration of the frame design, called Monocoque. Integrated frame in the traditional sense, that is, the main frame, the load beam, the housing, etc. as a whole, and the various parts bonded by welding. Explained literally integrated design will be more complex, but standing on the point of view of the depot, the emergence of integrated design, production speed of the vehicle can make the unprecedented increase, although the need for production frame processing machine huge cost, production efficiency, automation equipment, widely used, so reduce the cost of production of single-piece parts, so some depot annual production capacity of one million, if it was the other agencies, it is impossible to achieve.

Frame Design of the RX-8, belonging to the more traditional integration layout.

FORD's Mustand is also traditional integration layout can be seen carrying beams, fender, etc., are all part of the frame by welding the various components are joined together.

Although almost all of the production models are integrated frame design, but it also has many disadvantages, such as weight and metal material consumption is inevitable, but because it has a good impact resistance, the effective use of space large, and many a little, this design is still preserved, more car manufacturers spare no effort to explore effective solution based on the design, which come out of a variety of integration in the form.

Jaguar's integrated aluminum frame, a change in the era of all sheet metal, aluminum can effectively solve the problem of corrosion, weight, but to increase the rigidity you need even greater mechanical design.  

Talk about lightweight car with security

Two years ago, I wrote a article on the relationship between the lightweight automobile and traffic safety, but not officially published, this, once again the old title renegotiated.

Order to reduce body weight, such as high-performance models of the BMW M6 like to spend a carbon fiber roof, of course, in order of appearance.
Car lightweight for most of the the driving original car owners, there is not a negative factor, on the contrary, I have seen in all likelihood the owners of the car, will think that the car is heavier, the better outside. "Accord not too light, only one ton VI, not crashworthiness!"; "Benz good small one E-Class, almost two tons, security!" This is It is said that "for security", but this is simply is a fallacy. The increase in body weight for the depot is concerned, in fact, is a too awkward, consumers want their own car, foot interior space, luxury equipment naturally as possible, so that the car can be easy to sell, in order to reach the market demand, the depot Only consumes more steel, leather, plastic, even wood, the more exaggerated spend really marble to create a cabin atmosphere the car naturally generation than a generation, access to vehicle data will find most of the facelift car weight will surpass the previous generations. However, the increase in body weight, smattering of consumers on the car, which is a good thing, they think of is "thick steel plate"; "there are real leather"; "space many" but for these engine displacement increases, or to re-writing the trip computer, engine and more work is done, all know that the law of conservation of mass, right? Acting more, in addition to the technical factors in part from the increased combustion efficiency, more or because the fuel consumption increased. Increase in weight of the vehicle body, which also causes the other part of the load is also increased, the suspension system loads increase, inevitably lead to a decline in flexibility; naturally mention tire load; There are braking systems, a large weight, inertia the big braking system in addition to controlling the rolling friction, but also to control sliding friction, the great impact of the latter for security, I had tested a domestic facelift car, Body weight has been much greater than the previous generation, although the tires, etc. upgrade, but test the performance of the braking system, brake inertia people cold sweats.
