Definition of Aquaplaning


1 Meaning of Aquaplaning

Hydroplaning (more rarely, aquaplaning or hydrofoils) is the situation in which a vehicle crosses a surface water, leading to a loss of traction and control by the driver on the road at a certain speed. If esto occurs in all of the wheels, the vehicle becomes indeed, an uncontrollable sleigh. It is important to differentiate the hydrofoils of the effect that causes the water to act merely as a lubricant. Reduces traction on wet pavement even when the hydrofoils is not happening.

Causes of Aquaplaning

All function of a vehicle intended to change the direction or speed of the same, depends on the friction between the covers and the surface of the soil to act. The grooves on the cover are designed to drain the water that may lie underneath, increasing friction and ensuring control. Hydroplaning occurs when for various reasons, the cover is more water which is capable of evicting. The pressure of the water in front of the cover then forms a wedging under it, pulling it up from the floor and thus reducing or annulling the friction. Wheel, then, begins to skate over the surface of water with little or no contact with the pavement, drastically reducing control and braking capacity. The vehicle, once in I hydrofoils, it slips to collide with an obstacle or until its speed decreases enough so that wheels resume contact with the soil surface and friction is restored. The risk of hydrofoils increases with the depth of the water table and the sensitivity of vehicle to the same.


2. Definition of Aquaplaning

The phenomenon of aquaplaning (also known in Spanish as "hydrofoils") is a very common phenomenon that happens when a car or vehicle moves along a wet surface or with water, which makes the tires or tires to lose contact with asphalt or ground and can lose control of the vehicle.
It is understood that aquaplaning is a very common phenomenon, this does not make it less dangerous. This is so since it involves a possible loss of control of the car or vehicle when it ceases to have contact with the soil in which is moved by the presence of water. Thus, a highway or street flooded can generate aquaplaning causing the driver can not dominate as always the vehicle and it starts to scroll or move independently. Both the brakes and the steering wheel no longer have control over the car as it is moved or displaced by the water.
More is that the greater the amount of water present on the surface, harder it will control the vehicle, and can the same float even in the event that the water level is higher than normal. In other cases, when the water level the surface, loss of control is minimal and can be reencausarse easily.
Aquaplaning, as he said, arises from the moment in which the tires lose contact with the surface. They are specially designed to benefit the grip on different types of soil, which have highlighted and designed forms that allow a better grip and safety. However, when the surface is covered in water or other liquid, that grip is lost and tires are no longer stay on the ground. In addition to become difficult to maneuver, a car that suffers from the phenomenon of hydroplaning can not stop, by which this situation can easily lead to an accident or shock depending on driving. If we add to this that hydroplaning can happen at a moment in which the vehicle possesses much speed, the shock can be even worse.


3 Concept of Aquaplaning

What is hydroplaning?

The dangerous phenomenon of aquaplaning is the gradual loss of contact between the tire and the road surface, caused by the entrance of a thin layer of water, thickness greater than half a millimeter, between the two. To increase the speed of the vehicle, water cannot be quickly evicted from the front of the tire outward from its footprint, or expelled by the grooves in the same drawing, so the pressure on its base begins to increase. If the water is not evicted to the outside of the track, gets then between the tire and the road, literally lifting the wheel. Thus, aquaplaning comprises three stages. At first, the water pressure is increased by increasing the speed. Then, part of the water is evicted to the outside of the track and part is driven by the grooves of the tread. Finally, when the pressure value on the sheet of water not evicted nor driven is greater than the value of the weight on the wheel, tire comes off of the road. The direct consequences of this phenomenon are, aside the considerable increase in the distance of braking, and another, the loss of direction of the vehicle. Try to correct the aquaplaning has become one of the main concerns of the tyre manufacturers
