Description

Rainwater drainage tire {RAIN DRAIN TIRE}

The present invention relates to a rainwater drainage tire, and more particularly, to a rainwater drainage tire that minimizes slip due to rainwater during driving.

In general, automobiles are provided with tires to support a load and transmit rotational force from an engine to the ground, and performance such as driving speed, fuel efficiency, and noise of the automobile is greatly affected by the tires mounted on the automobile. Accordingly, recent tires require excellent durability as well as stability at high speeds, and performance that allows them to run stably on rain or snowy roads is required.

In particular, not only the climate continuously changes, but also the instantaneous precipitation increases every year, driving on rainy roads becomes more frequent, and as a result, the importance of the drainage performance of tires is increasing. If the tire does not have sufficient drainage performance, an aquaplaning phenomenon occurs between the tire and the road surface, making it impossible to maneuver the vehicle. To solve this problem, improvement of the drainage performance of the tire is inevitable.

The tread of a general pneumatic tire is formed in a substantially flat shape or a flat shape having a fine curvature so as to secure a sufficient contact area and distribute a load. However, such a pneumatic tire equipped with a flat tread has a disadvantage in that it is vulnerable to a hydroplaning phenomenon.

The hydroplaning phenomenon refers to a phenomenon in which controllability is suddenly lost when a vehicle travels at high speed on a road covered with water. In other words, when there is water on the road surface due to heavy rain or the like, when the car is running at low or medium speed, the water under the tire is splashed off and the contact between the tire and the road surface is maintained, but the speed exceeds a certain level. When this happens, there is no room for water to splash between the tire and the road surface, the tire loses contact with the road surface, and the tire slides on a thin film of water, which makes steering and braking difficult, resulting in an accident. .

For this reason, in the tread of a pneumatic tire, longitudinal grooves are formed along the running direction of the tire and transverse grooves are formed along the width direction of the tire so as to secure various performances required of the tire. The longitudinal groove of a tire is related to drainage performance, and the transverse groove is related to grounding performance.

A technology related to a tire for actively discharging water flowing into a groove extending in the circumferential direction of the tire has been proposed in Korean Patent Registration No. 1002919.

However, Patent Document 1 has a problem in that the drainage area is small and the performance of preventing water film is not sufficient.

It is a side view showing a state in which rainwater is introduced in a state where the rainwater drainage tire is in contact with the road surface.

1 to 4, the rainwater drainage tire 100 according to an embodiment of the present invention includes a tire body 110, a suction port 120, an outlet 130, and a discharge path 140, and Between the furnace 140 and the discharge path 140, patterns by the inlet 120 and the outlet 130 having a polygonal structure are continuously formed along the circumferential direction.

As shown in FIG. 1, the tire body 110 is provided in a form extending in a circumferential direction around a central axis, and a rim (not shown in the drawing) is coupled therein.

As shown in FIGS. 1 to 4 , the inlet 120 is recessed on the surface of the tire body 110 at set intervals in the circumferential direction, and when in contact with the road surface during driving, the pressure formed inside the inlet 120 removes rainwater and the like. induce inhalation. In this case, the subject to be sucked in includes not only rainwater (water) but also dust, which is a foreign substance remaining on the road surface.

That is, the suction port 120 is sucked into the inside of the suction port 120 while pressure is formed when the suction port 120 contacts the road in a state where rainwater or the like is accumulated on the road.

As shown in FIGS. 1 to 4, the outlet 130 is radially formed with respect to the inlet 120, and the side surface of the inlet 120 and the discharge opposite thereto are spaced apart from the surface of the tire body 110. It communicates with the side of furnace 140.

At this time, the outlet 130 includes an inner outlet 132 and an outer outlet 134 .

The inner outlet 132 is a passage radially formed around the inlet 120 .

The outer outlet 134 is a passage through which the end of the inner outlet 132 and the end of the inner outlet 132 adjacent thereto communicate with each other.

In addition, the front and rear corners of the outer outlet 134 communicate with the front and rear corners of the outer outlet 134 extending from the adjacent suction port 120 .

Moreover, the outer outlet 134 and the inner outlet 132 are provided in a symmetrical structure in both the circumferential direction of the tire body 110 and the wheel axial direction at the center of the inlet 120 .

On the other hand, the outer outlet 134 is in communication with the hexagonal structure, etc., and the end of the radial inner outlet 132 communicates with the inlet 120 at each corner, and the outer outlet 134 and the outlet 140 are adjacent to each other. The openings 136 communicate with each other at two corners where the outer outlet 134 is connected. This means that the inlet 120 communicates with the outlet 140 via the inner outlet 132 and the outer outlet 134 .

In this way, since the outer outlet 134 and the inner outlet 132 are provided in a hexagonal structure, etc., and are formed symmetrically in the longitudinal and lateral directions, the front of the hexagonal structure gradually touches the road surface when driving while mounted on the vehicle As it gradually widens, it helps to prevent slip and provide the instantaneous force necessary for hitting and running, and the contact area at the back of the hexagonal structure gradually becomes smaller, which helps with braking. In addition, the center and left and right sides of the hexagonal structure maintain the center of the body due to the symmetrical structure, enabling safe driving.

On the other hand, when the outer outlet 134 and the inner outlet 132 are provided in a hexagonal structure, the same function is performed even when the vehicle moves forward or backward, and the rainwater discharge tire 100 is moved from the driver's seat (passenger's seat) to the passenger's seat for tire replacement. If you move it to the opposite side like (driver's seat), the same function will be performed.

In addition, the outlet 130 may be formed inside the surface of the tire body 110 by separately manufacturing the upper and lower portions during the molding process of the tire body 110, for example, and then bonding them together.

In addition, although not shown in the drawing, the outer outlet 134 is inclined so that each intermediate inner diameter is narrower than the inner diameter of the inlet and outlet.

In this way, the outer outlet 134 applies Bernoulli's theorem that the speed increases when the area is narrowed so that the inner area is smaller than the area of the inlet communicating with the inlet 120, thereby increasing the flow rate of the incoming rainwater and discharging the rainwater more quickly. possible.

In addition, although not shown in the drawing, the opening 136 is provided with an opening for opening and closing at one end so as to be foldable, and is closed when rainwater or the like is sucked through the inlet 120 to the inside of the outer outlet 134 and the inner outlet 132. The suction of rainwater is facilitated by the pressure applied while being sealed, and when rainwater is discharged from the outer outlet 134 to the discharge passage 140, it can be opened by rainwater.

As shown in FIGS. 1 to 3 , a plurality of discharge passages 140 are formed along the surface of the tire body 110 in the circumferential direction, so that fluid or foreign matter sucked through the suction port 120 is transported through the inner discharge port 132 and It is formed to be discharged to the outside of the tire body 110 through the outer discharge port 134.

At this time, a plurality of discharge passages 140 are formed between both edges (beads) of the tire body 110 and therebetween, and a pattern for discharging rainwater is continuously formed between them.

Therefore, the process of discharging rainwater and the like through the rainwater drainage tire 100 of the present invention will be described as follows.

First, when the vehicle is driving on a road with accumulated rainwater, when the suction port 120 of the tire body 110 comes into contact with the road surface, pressure is formed inside the suction port 120, and the rainwater collected on the road surface is removed due to the pressure difference with the outside. is inhaled At this time, since only the inlet 120 is exposed to the outside on the outer surface of the tire body 110, rainwater flows in through the inlet 120.

Next, the rainwater introduced through the inlet 120 moves from the inlet 120 to the radially communicated inner outlet 132, and some rainwater moves from the inner outlet 132 to the outer outlet 134 while moving to the outer outlet. It is discharged to the discharge path 140 through the opening 136 formed at the corner where the 134 and the outer discharge port 134 are connected.

Next, the remaining rainwater moves from the inner outlet 132 to the outer outlet 134 while moving to the inner outlet 132 and the outer outlet 134 of the adjacent front and rear patterns, and subsequently flows in through the inlet 120. It is combined with the rainwater and discharged to the discharge path 140.

Next, the rainwater discharged to the discharge path 140 through the opening 136 is discharged to the road surface through the discharge paths 140 on both sides.

Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art to which the present invention pertains can be implemented in other specific forms without changing the technical spirit or essential features of the present invention. you will be able to understand Therefore, the embodiments described above should be understood as illustrative in all respects and not limiting.
