1 racing grip
Introduction:
body generally to a force to the ground. It depends on tires, vehicle weight, body shape and so on. Grip size affects the car start, acceleration, cornering and braking, and so on.
increasing the tire grip several ways:
a, increasing friction tire and the ground
To increase the tire and the ground friction there are two ways to achieve this purpose. The first is to increase the friction coefficient of the road surface, so-called ldquo; friction coefficient rdquo; pavement is offered in grip ability of the tire, the greater the coefficient of friction greater grip is attached. Asphalt, concrete pavement, gravel roads have different coefficients of friction. Offered in grip tire is also different. Second is to increase the coefficient of friction of the tire itself, which can be selected to achieve a softer tire. Softer tire provides strong grip, but the relative wear faster. Here the so-called ldquo; soft tire rdquo; refers to the tire tread rubber material is relatively soft, and if higher than the flat tire and tire pressure caused by insufficient road of softer, more comfortable associate it would be wrong!
Second, the increase of the tire ground-contacting area
and to increase the area of the tire contacting the road surface, the easiest way is to put wider tires, again it is to use less of the tire tread, so to increase the actual contact area between the tire and the ground, but it will also affect the wet traction performance. Finally, and most important is that at a given ground area, through proper tire pressure and suspension of precision-tuned to take full advantage of the potential of the tires. Ground area of the tire even when driving on a flat straight road will still be less than, or more uneven road passing through because of the force of beating up and down or sideways, causing a significant reduction in the contact patch when cornering, even vacant. Suspended ultimate goal is to improve as much as possible at all times to keep the tires in contact with the ground, especially in the pastBend when passing or uneven pavement.
Third, the increase in the vertical load of the tire
is the vertical load of the tire of the vehicle itself plus the weight of the tire is administered at a pressure of the aerodynamic effect of the generated sum. Rubber tires because of the increase of the vertical load and closer contact with the ground, the grip performance of the tire also be more fully exploited. Unlike everyone cognition, increase the vertical load of the tire does not increase the ground area of the tire, at least in modern high-performance tires and racing tires are almost always the case, increase the vertical load is increased within the tire contact area , within each unit area of ground rubber and adhesion molecules. In the case of the ground contact area is constant, increasing the grip of the tire due to the pressure exerted by the rubber molecules increases. We can do a little experiment: Move the eraser on a smooth plane, in the case of no pressure is applied above the eraser, we can very easily move freely erasers, eraser when we are pressing, it becomes to move less likely, the stronger the greater the adhesion strength rubber pressure generated, that is, the better the grip. Vertical load of the tire seems to be achieved by increasing the vehicle weight, although this can increase the tire’s grip, but because the tire is subjected to load from the vehicle weight increases, so cornering speed, braking distance, acceleration performance is not improved . In fact the overall performance but because of an increase in vehicle weight deteriorate. To improve the vertical load of the tire without damaging the overall performance, the only way is through the aerodynamic design of the body to learn to achieve.
