Description

Aerodynamic device for tires.

Object of the invention

This utility model refers to a device that allows aerodynamic improvement of the vehicle while this is underway, thanks to the incorporation of a transparent sheet that covers the gaps existing in the car's tire at high speeds, generating better air circulation without producing high visual impact.

Background of the invention

At present, they tend to create models of tires with large free surfaces between spokes. These free surfaces have a high aesthetic function, but they also help improve internal brake cooling, thanks to the constant circulation of refrigerated air at high speeds, and the evacuation of waste resulting from wear of the brake pads, if the vehicle is equipped with disc brakes.

However, such tires so designed, cause in turn certain problems caused largely by the low aerodynamic efficiency of the set. This problem may not. show up during urban traffic due to low speed Cruising that is maintained. With the increase of said speed of cruise, this problem is becoming more important. Therefore, the number and intensity of the turbulence in the tires  It is directly proportional to the cruising speed, damaging the overall aerodynamic efficiency of the set.

Similarly, a seemingly solution obvious, as is to constantly cover free gaps, it would cause premature depletion of the brakes, especially in urban driving, where most of the braking

Description of the invention

To alleviate the problem mentioned above, it presents the aerodynamic device for tires, object of present utility model because, thanks to it, you get a correct balance between braking efficiency and aerodynamic efficiency of the car. Said device comprises, at least:

A.- A plastic sheet interposed between the set of brakes and the tire, covering the hollow spaces between radios, comprising, in turn:

(i)

A plurality of weakened areas; Y

(ii)

A plurality of holes.

B.- A protection ring arranged in the area back of the sheet.

Where said plurality of weakened areas cause, at low speeds, the segments between these areas bend; similarly, at high speeds it would unfold thanks to the performance of the centrifugal force.

Likewise, if during the course of the circulation by a fast track there is a strong braking, the force itself of braking would boost the bending of the segments, reaching extra cooling of the brakes.

The protection ring allows the support of the blade when it is in a folded position preventing everything case the possible rubbing with internal mechanical elements, ensuring Good system operation.

The fixation of the device must be as sufficiently stable, preventing any displacement that reduce the effectiveness of the whole. Therefore, it has been considered the use of the holes through which the screws that are inserted fix the tire to the rest of the shield. Although because they exist different screw sizes and arrangements must be made several sheet models, at least one for each arrangement of sheet.

Thus, with the device thus described, it manages to maintain adequate cooling of the system restrained on urban roads, since it does not cover free spaces, while in interurban roads you get a better aerodynamics being these holes covered, assuming that in such fast roads the use of the brake is not as frequent as in urban roads.

The operation of the device is the next: With the vehicle stationary the blade is in folded position, that is, the different segments that make up The blade is supported by the protective ring. To the undertake the march, and circulating at low speeds, the system remains folded, ensuring proper system cooling of braking This phenomenon is due to the fact that on urban roads it is when the action of the braking system and the refrigeration must be correct to avoid depletion premature. When reaching a certain speed, when the force centrifuge is high enough, the segments of the foil unfold through weakened areas, occupying spaces free that exist between the spokes of the tire. Thanks to this occupation is achieved a better aerodynamic flow conduction, improving the aerodynamic properties of the vehicle, which translates into a small increase in acceleration and a reduction of consumption. In this position the braking system does not receive a extra cooling, since its use on fast roads is reduced to specific cases or emergency braking. In the event of a emergency braking, the braking force itself would push the segments of the blade towards the inside of the tire, emptying the free spaces to some extent and allowing a correct cooling of the braking system.

The main advantage of the present innovation responds to the need to improve the aerodynamic parameter of vehicle. Thanks to the incorporation of the aerodynamic device for rims a better aerodynamic flow guidance is achieved by the exterior of the vehicle, improving acceleration to some extent of the vehicle and consumption. A remarkable advantage of the device proposed is that proper cooling of the system is maintained of braking in the conditions where a good one is required performance of such a system, but this cooling is dispensed with unnecessary for fast road traffic, where this System does not act as regularly. As an additional advantage, the aerodynamic tire device can have a character aesthetic, customizing to the user's taste through paints or decorations, providing in any case a differential aspect and Shocking in the vehicle.
