Have you ever driven a light truck?But if a few people have driven, they will not think that the high-speed drifting is caused by the light car.
This idea is as absurd as the idea that if you grow short, you can't eat the fruit on the tall branches, because you can use other means to eat the fruit, and there is no doubt that the car has nothing to do with running at high speed. As a chassis system that can directly carry the handling height and low, its design and tuning is a very systematic and complex work.
The performance of the handling can be directly fed back to the high-speed driving state.
To put it simply, the design direction of the chassis system determines its overall use effect, and the high-speed driving experience is only a reflection.
The chassis system is not simply what you think is only one chassis, the suspension system, the four-wheel drive system, the weight configuration, and the steering system are all points that should be considered in the design of the chassis system.
In fact, whether you run at high speed or not, the key depends on the following factors.
1. Wind resistance coefficient.
The drag coefficient is still the focus of consideration, the mass of hundreds of kilograms of sports cars can ride the wind and waves at a speed of 200km h, the fundamental reason is that the aerodynamic design is excellent enough, enough downforce can press the vehicle on the ground, the drag coefficient needs to consider the chassis layout, ground clearance, vehicle shaping, for family cars, the drag coefficient is more workmanship is to reduce driving resistance, improve the performance of a small amount of fuel consumption.
But even so, it's still a design focus.
2. Suspension travel.
This is the point, the length of the suspension travel is crucial, the long stroke suspension can provide a better support platform for comfort and off-road, but cornering is really a little less confident, after all, the greater the compression travel of the one-sided suspension, the confidence of the driver is also an impact.
Generally speaking, long-stroke suspension is more used in off-road, family cars, and the style is more homely, but it is obvious that this suspension can not bring better handling performance.
The vast majority of sports cars use a relatively short suspension compression stroke, and the wheels and body can interact closely at all times, which can provide a greater and better premise for excellent handling.
3. Steering system.
Whether the control is good or not, the feel is very important, the era of mechanical assistance is gone, replaced by the era of electronic assistance, how to adjust, how to have a texture of the tune is very important, light means that there is no texture, needless to say, there is toughness on behalf of the vehicle can have a good interaction process with the driver.
Therefore, a good steering system must not simply release gravity for women's considerations, it should be a resilient feedback, so electronic power companies have their own play points, a good steering system is accurate, tough, and has a sense of pulling, so as to bring stronger confidence to the owner.
In fact, fundamentally speaking, the suspension stroke is more important, if you want to fly close to the ground, the suspension must not be long, and the steering feel should always interact with the driver, maintaining toughness and pulling, which is very important.
