Description

  When the road surface is wet or when it rains, water splashes behind the tires due to the running of the car, splashes it up, makes the rear part of the car muddy, and diffuses backward to contaminate the rear periphery. The present invention relates to a diffusion suppression device that is provided around the tire of such an automobile and prevents the dispersion of scattered matter such as water spray and mud of the tire, and more particularly to a diffusion suppression device around the tire of a transport vehicle such as a truck or a trailer. .

  Usually, rubber tire mudguards on the fender and the rear lower side of the fender are attached to the tire house of the wheel of an automobile, and the splash and mud that are repelled from the tire by the fender and rubber mudguard of the tire house are suppressed. By the way, a transport vehicle such as a truck has a large tire diameter and is wide, and a plurality of tires are arranged adjacent to each other. For this reason, conventional tire houses and mudguards do not have sufficient effects of suppressing splashing, and the splashing hinders driving of the following vehicle and oncoming vehicle.

  The anti-splash system for preventing the splash of water from the tires of the traveling vehicle is a system that mainly reduces the atomization and splashing of the splashed water. In addition to the anti-splash device, this anti-splash system consists of mudguards, rear-infrared, and balance. Of these, the anti-splash device comprises an air / water separator and a spray energy absorber for mist-like spray. Mudguard consists of a rigid or semi-rigid component intended to prevent the water splashed from the tires during travel and to direct the splash water toward the road surface. This mudguard is usually integrated with a part such as a body part or a lower part of the loading platform, or partly integrated. A lainup is a flexible part mounted perpendicular to the rear of the wheel below the chassis or loading surface or on the mudguard. This lean-up reduces the impact of small things on the road, especially pebbles, on the tires and hitting people on the road by flying upwards or sideways.

  In order to prevent such splashing and splashing of transport vehicles such as trucks, various splashing prevention devices have been developed. For example, there are mudguards with vegetation with surface shapes such as artificial turf on the surface, but this is loosely provided with projections and is effective for splashing, but it is effective for scattering mud etc. It was not enough. In addition, during snowfall, there is a risk that the snow freezes on this device and the snow mass frozen during traveling and the scattering prevention device itself that snow has fallen fall off.

  For this reason, these devices were used only on rainy days, and it was not possible to sufficiently prevent the scattering of scattered objects on the road surface in fine weather. In addition, the drainage ribs are arranged with an appropriate space between the protrusions in the vertical direction and guided, and the splashes covered with the triangular cross-section net are made to easily pass through, making it difficult to return, and wind pressure. Splash reduction devices for heavy trucks that are difficult to turn up are commercially available. Furthermore, a mudguard device has been developed that includes a weakening device and a guide groove that are attached to the surface of the fender around the conventional tire and the rear of the fender and used (see, for example, Patent Document 1 and Non-Patent Document 1). This is to collect splashing water at a certain location by the guide groove and to flow down, and is excellent in preventing splashing of rainwater. However, this mudguard device is provided with a multi-stage vane obliquely upward, for example, from the lower part of the vertical plane to the vicinity of about 125 degrees. It was found that the effect of weakening the splashing can be obtained sufficiently, but there is almost no effect of diffusing the scattered matter. That is, in these prior art mudguards and splash prevention devices, there is a problem that various scattered objects from the road surface must be captured more effectively. Furthermore, there is a problem that the apparatus can be easily cleaned.

Japanese Patent Laid-Open No. 10-316037 Registered Design No. 1060901 Design Gazette

  The problem to be solved by the present invention is to solve the above-mentioned problems of the prior art, which can suppress re-scattered objects from vehicles such as automobiles, and in addition to these, snow adheres and falls. This is to provide a vehicle diffusion prevention device for roadside environment-friendly vehicles such as roadside environment-friendly vehicles, such as excellent visibility of rainy days, prevention of rear-end collisions, and compatibility with all weather conditions. .

  The means of the present invention for solving the above-mentioned problems is a synthetic rubber or synthetic resin flat plate made of a rectangular main body formed by arranging thin blades that protrude horizontally and obliquely downward on the surface in a multistage manner, A vertical pipe made of a circular pipe having an opening extending over the entire length in the vertical direction on both sides of the flat plate, and left and right vertical ends of the flat plate having multistage thin blades at the opening of the vertical pipe This is a device for suppressing the dispersion of scattered matter such as water spray and mud of a vehicle tire.

  2. The vehicle according to claim 1, wherein the thin blades projecting horizontally and obliquely downward on the surface of the flat plate have a blade projection angle of 30 to 45 degrees with respect to the downward surface of the flat plate. This is a device for suppressing the dispersion of scattered matter such as water spray and mud.

  Further, the thin slats projecting horizontally and obliquely downward on the surface of the flat plate have a circular arc shape whose tip is directed downwards. It is a device for suppressing the diffusion of scattered matter such as mud.

  The scattered matter diffusion suppressing device of the present invention efficiently collects splashes splashed by the tire of a traveling vehicle from the road surface, and further improves the rear field of view by suppressing re-scattering as a diverging material from the device. It has excellent effects such as preventing the occurrence of rear-end collisions.

  The best mode for carrying out the present invention will be described with reference to the drawings. FIG. 2 shows the air flow around the rotating tire 2 when the vehicle 1 is traveling. The wind A that is wound up from the road surface 3 by the tire 2 and the wind B that is generated by the traveling collide violently around the point 4, and the wind C is vigorously ejected to the outer side of the vehicle 1. This wind C is a genius that diffuses various scattered objects into the surrounding environment.

  Therefore, as shown in FIG. 3, when only the element of the wind A wound up from the road surface 3 by the tire 2 was taken out and the flow of the air was examined, it reflected on the inner surface of the rubber mudguard 5 and the inner surface of the fender 6, There was no wind C as shown in FIG.

  On the other hand, as shown in FIG. 4, when only the wind B element generated when the vehicle 1 travels is taken out and the flow of air is examined, it is reflected on the upper surface of the tire 2 and the inner surface of the fender 6. C was not generated.

  From this, if either element of the wind A wound up from the road surface 3 by the tire 2 or the wind B generated by traveling is suppressed, the wind C is suppressed.

  Therefore, as shown in FIG. 5, by attaching the diffusion suppressing device 7 for splashes and mud of the present invention to the inner surface of the mudguard 5 and the inner surface of the fender 6 a at the rear of the fender 6, By receiving the wind A that is wound up from 3 and making the wind B generated by traveling easier to flow, the generation of the wind C to the rear side due to the collision of these winds can be suppressed.

  That is, as shown in FIG. 1, in the diffusion suppressing device 7, the tip 9 in the shape of the blade 8 protrudes downward and inward, so that the wind A can be received more easily, and the flow of the wind B The shape is difficult to buffer, and the direction of the flow of the wind A can be the same as the direction of the wind B, and the collision at the point 4 shown in FIG. 2 is suppressed. The wind A reliably received in this way is discharged to the lower road surface 3 through the discharge grooves 12 of the longitudinal conduit 10 formed of circular pipes provided at both ends of the diffusion suppressing device 7. In this way, the spray and mud are discharged only into the discharge grooves 12 of the two longitudinal conduits 10 provided on the left and right of the diffusion suppressing device 7.

Furthermore, the optimum angle α shown in FIG. 6 was obtained for the angle α of the protruding shape of the tip 9 of the blade 8 of the diffusion suppressing device 7 by the test device shown in FIG. In the flat plate 13 having the tip of the blade 8 having the cross-sectional shape shown in FIG. 6A facing downward, the angle of each blade 8 from the downward direction of the flat plate 13 as shown in FIG. The angle α was changed from 0 to 180 degrees, and the relationship between the angle α of the blade 8 and the water diffusivity was examined. The test method is based on the European Community part certification test shown in FIG. 7, and the 200 μm sand particles are monitored by the pressure reducing valve 21 with the injection device 20 of the high pressure blast machine 19 and the injection pressure of 2 kg / mm ³ is used. Rated injection was performed on the test plate 22 of the diffusion suppressing device 7 of 750 mm × 500 mm having the movable vane plate 8 as a total injection amount of 4 kg.

  In FIG. 7, when all the ejected particles are collected by the measuring instrument 23, the scattering rate is 0%. The scattering rate SP (%) was determined by the following equation (1) from the mass Q1 of sand before spraying and the mass Q2 of sand absorbed by the test plate.

  SP (%) = 100 · (Q1-Q2) / Q1 (1)

  The results are shown in Table 1 and FIG.

  As a result of the above test, when the angle α of the blade 8 was 45 degrees, the scattering rate was 42.1% and the efficiency was the lowest. In the conventional apparatus, the angle α of the blade plate 8 is set to around 125 degrees, but it has been found that a sufficient effect cannot be obtained at this angle.

  Therefore, the present invention provides a flat plate 13 composed of a rectangular main body in which thin blades 8 that protrude horizontally and obliquely downward are provided on the surface of the flat plate 13 and the total length in the vertical direction on both sides of the flat plate 13. A vertical pipe 10 composed of a circular pipe having an opening 11 extending up and down is provided, and the flat plate 13 of the rectangular main body and the left and right openings 11 of the multistage thin blades 8 are formed in the opening 11 of the vertical pipe 10. It is a diffusion suppression device 7 for splashed matter such as splashes and mud generated during traveling from the tire 2 of the vehicle 1, characterized in that the vertical end portion 18 is inserted into the longitudinal conduit 10. Is also formed from synthetic rubber or synthetic resin.

  Furthermore, the thin blade 8 that projects horizontally and obliquely downward on the surface of the flat plate 13 of the diffusion suppressing device 7 having the above-described configuration has an angle α at which the blade 8 protrudes with respect to the downward surface of the flat plate 30 by 30. -45 degrees.

  Further, the thin blade 8 that projects horizontally and obliquely downward on the surface of the flat plate 13 of the diffusion suppressing device 7 having the above-described configuration has a circular arc shape with the tip 9 facing downward.

As shown in FIG. 9, the blades 8 projecting obliquely downward in an arc shape and having a tip 9 at a 45-degree angle from the projecting root and having a thickness of 2.5 mm, a height of 11 mm, and a width of 13 mm are multi-staged at intervals of 20 mm. The flat plate 13 serving as a basic unit having a length of 441 mm is formed from synthetic rubber. The thickness of the portion of the flat plate 13 is 3 mm. By providing engagement recesses 15 and engagement protrusions 17 that fit each other at both ends of the upper end 14 and the lower end 16 of the flat plate 13, the length of the flat plate 13 can be extended. The lateral width of the flat plate 13 is set to match the width of the tire 2 of the vehicle 1. When this flat plate 8 is mounted on the fender 6 of the vehicle 1, it is locked with a rivet or the like as appropriate. The longitudinal conduit 10 is fitted to the longitudinal end portion of the flat plate 13. FIG. 10 shows a cross-sectional view of the longitudinal conduit 10.
