Why do I need a spoiler for a car? Its advantages and disadvantages
Tuning cars now in vogue. In addition to various skirts and other fashion elements, spoilers on the car are popular. Some drivers perceive them as design elements, others are confident that this body element provides some advantages. Let's try to figure this out.
Why a spoiler by car?
Let's start with a simple one. This element sets the style of the whole car and makes it sporty, unique. It is for styling cars that it is used in the first place. Secondly, it is used as a practical element, which improves the aerodynamics of the car, redirecting the flow of air. In simple words, the spoiler at high speed allows you to squeeze the back of the car to the track, which will contribute to better traction of the wheels with asphalt. On machines without a spoiler at high speed, the rear is raised by the flow of air under the body of the machine. Clutch for this reason is getting worse.
How does the spoiler work on the machine?
At high speed, counter-flow of airbecomes strong. He gets under the bottom of the car and raises the body above the road. At the rear of the car, vortex streams of air are formed, which slow it down a little. All this increases the aerodynamic loads on the machine. The spoiler allows you to direct the streams in the right direction, which will eliminate unnecessary loads.
It is recommended to install two spoilers: in the front and in the back. The rear presses the rear of the car to the track at high speeds, which allows you to slightly unload the front axle. The front element presses the front axle. It also can be integrated deflectors, which direct air flow to the brake pads or disks, which contributes to their better cooling.
Depending on what exactly the owner wants to achieve by introducing this constructive element into the design, the spoilers can be divided.
According to the design they are:
- Custom. Produced according to the individual design of the customer. It is an expensive unique thing that no longer meets anywhere.
- Factory. Produced in the factory, produced in large batches and have the appearance of a factory structural element.
By the method of fastening:
- Support. Mounted with the help of special supports, which are often simple screws or bolts. Despite the rudeness, it is quite reliable fasteners.
- Sticky. You can guess the method of fixing already from the name. Such spoilers are attached with the help of double-sided adhesive tape or glue. The reliability of such fastening is not credible. There were cases when at high speed such elements banally flew from cars.
In the place of installation:
- The rear. Usually they are installed on the trunk or below the rear window.
- For the roof. Most often installed on hatchbacks, rear doors.
- Skirts for the rear and front bumper.
- Diffusers. They can not be noticed, because they are installed under the bottom of the body.
- Side spoilers, which are the lining on the threshold of the machine.
- Universal - can be installed on many machines.
- Special - are placed only on a specific model at the factory.
A spoiler on a car can have both advantages,and shortcomings. To begin with, this is not just an expensive toy, but an expensive construction element that can even harm the car. If it is installed by a person who is not versed in the topic, he will most likely perform the installation incorrectly. And then such an element on the machine will be useless, and at high speed even dangerous. Then why do you need a spoiler by car? Its main purpose is to strengthen the adhesion of tires to the road, improve handling. This can only be achieved if the installation is correct.
So, the main advantage of installing thisconstructive element - improving the controllability of the car by increasing the coefficient of adhesion of the rear wheels to the road. The car will not tear apart.
The second advantage is a reduction in fuel consumption.Air streams at high speed create resistance to the movement of the car, because of what there is a feeling that it slows down. The driver at the same time tries to maintain the speed and presses the gas pedal, which leads to a fuel overrun. The spoiler allows to reduce air resistance, which causes a reduction in the consumption of gasoline.
Additional security is anotherThe reason explaining why a spoiler is needed on a car. Due to the fact that this part redirects the flow of air during the movement, the probability of transport skidding is reduced, and it becomes more maneuverable. The risk of an accident is reduced. He also makes braking more effective, especially in winter. And if additional threshold expanders are installed on the sides, the braking efficiency will be even higher.
Disadvantages occur only ifthis item will not be installed correctly. Incorrect position relative to the opposite airflow will significantly worsen aerodynamics, air resistance will be increased, and this will lead to an additional fuel consumption. Also, in the event of a drop in handling, the car is much more difficult to straighten, and at high speed, the clearance between the road and the bottom will greatly decrease. This is dangerous in bad roads. All these shortcomings are clearly visible in plastic spoilers on the car.
The properly installed spoiler is indeeduseful and effective, so the desire of many owners to establish it is logical. Some drivers want to know how to make a spoiler for a car on their own, but the occupation is bad. To make yourself a spoiler, you need to make an aerodynamic calculation of the car and only then determine the shape of the future element and the location of its installation. Otherwise it will go to the detriment, therefore independently it to make and establish it does not turn out.
