Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mudguard device for an automobile that prevents splashes thrown up by tires, particularly front wheel tires.

Water and mud adhering to automobile tires are splashed into the tire house by the centrifugal force caused by the rotation of the tires. Among the splashes thrown up in this way, relatively large particles cross the airflow induced by the rotation of the tire and adhere to the fenders, splash boards, etc. that form the tire house. However, small-sized splashes ride on the air flow and float inside the tire house.

In addition, since negative pressure or airflow turbulence occurs on the sides of the vehicle, especially on the outside of the front wheels, the splashes floating in the tire house as described above flow out to the outside of the fender. The negative pressure or turbulence of the airflow may cause the particles to be blown up and stain the sides of the vehicle.

In order to prevent such splashing, the volume of the tire house should be sufficiently large, or the outer wall of the fender forming the tire house should be It is effective to let the skirt hang down from the bottom edge.

However, due to structural constraints in a cap-over vehicle, it is not possible to make the front wheel tire house sufficiently large. In addition, if a highly rigid mound guard (skirt) made of plastic or metal molding is provided as in the latter case, the side opening area of the tire house will be reduced by the skirt, so the tire (wheel ), and if the steering angle of the front wheel becomes large, the tires of the front wheel will interfere with the muzzle guard, so there is a problem that the muzzle guard cannot be made sufficiently large. In order to solve this problem, if the muzzle guard is made of a highly flexible material such as synthetic rubber, it will be difficult to install the muzzle guard because its rigidity is low compared to its weight. There was a problem.

The present invention was developed to solve these conventional problems, and is a mudguard for automobiles that not only prevents the volume of the tire house from expanding, but also prevents splashing without impairing the workability of installing and removing tires. The purpose is to provide equipment.

In order to achieve such an object, the present invention includes bending the lower end of the outer wall of the fender, which forms the tire house in which the front wheel is housed, into the inner side of the tire house to form an engagement step, and An engaging stepped portion that abuts and engages with the mat guard from above is formed on the outer surface near the upper end of the mudguard made of a highly flexible material. Further, the head of a bolt for tightening and fixing the upper end of the mudguard to the inner surface of the lower end of the outer wall of the fender is fixed by welding in a recess provided on the outer surface of the fender, and the head of the bolt is fixed by welding in a recess provided on the outer surface of the fender. The recess is covered with a hardening plate.

This configuration improves the workability of installing the muzzle guard, which is made of a highly flexible material, and the muzzle guard, which normally reduces the side opening of the tire house to prevent splash from flowing out, When attaching or removing tires, the tires can be bent (elastically) deformed to widen the side of the tire house, and even if the steering angle becomes large and the front wheel tires interfere with the mudguard, , so as not to cause any particular trouble.

An embodiment of the present invention will be described in detail below based on the drawings.

In the figure, 1 is a front wheel, and 2 is a tire house that is a mounting space for the front wheel 1.

The tire house 2 includes a fender 4 and a splash board 4' attached to the cab 3, a side splash board (not shown) attached to the lower surface of the floor of the cab 3, and the like.

By bending the lower end of the outer wall of the fender 4 inward, an engagement step 4a is formed at the lower end. A recessed portion 4b is formed by recessing a predetermined portion of the outer wall relative to other portions.

Reference numeral 5 denotes a mud guard that hangs down from the outer wall of the fender 4, and is made of a highly flexible material such as synthetic rubber. This Matsudo Guard 5
An engaging stepped portion 5a is formed on the outer surface near the upper end of the mat guard 5 so as to abut and engage with the engaging stepped portion 4a from above, thereby positioning and holding the mud guard 5.

On the other hand, the engagement step portion 4 formed as described above
The mudguard 5, which is superimposed on the inner surface of the outer wall of the fender 4 by the positioning and engaging action of the bolts 6a and 5a,
The head 6a of the bolt 6 is directly welded and fixed in the recess 4b, and the head 6a is embedded in the outer surface of the fender 4. Then, the recess 4 is fixed by the kicking plate 7 attached to the outer surface of the fender 4.
It covers b. 6b is a cap nut that tightens and fixes the mudguard 5 to the fender 4 together with the bolt 6, 6c is a washer, and 5b is a positioning rib formed on the inner surface of the mudguard 5 to regulate the mounting position of the washer 6c.

In the above configuration, water, mud, etc. adhering to the tires become splash and float inside the tire house 2. Furthermore, since an air flow is generated in the tire house 2 as the tire rotates, the splash tends to flow out from the outer end of the fender 4 riding on this air flow.

However, since the muzzle guard 5 hangs down from the outer wall of the fender 4 as an extension thereof, the splash that is about to flow out as described above is blocked by the muzzle guard 5, and eventually spills onto the inner surface of the muzzle guard 5. It sticks and drips. Therefore, almost no splash flows out from the tire house 2, and the side surfaces of the vehicle body are prevented from becoming dirty.

For this reason, there is no need to make the outer wall of the fender 4 hang down significantly at the expense of the workability of attaching and detaching the wheel. Note that the muzzle guard 5 substantially extends the outer wall of the fender 4;
Since it can be bent freely, there is no risk of impairing the operability of attaching and removing the wheel.Moreover, even if the steering angle becomes large and the tire of the front wheel 1 interferes with the muzzle guard 5, the muzzle guard 5 can be freely bent and deformed. Therefore, no particular problems will occur.

Also, when installing Matsudo Guard 5,
First, the engaging step portion 5a provided on the outer surface near the upper end of the mud guard 5 is brought into abutment engagement with the engaging step portion 4a of the fender 4 from above, and the mud guard 5 and the fender 4 are brought into contact with each other.
Position (place) the and in the vertical direction. Next, using the engaging step portions 4a and 5a as guides, the mat guard 5 is
After moving them in the front-back direction and positioning them both in the front-back direction, they can be tightened and fixed with the bolts 6.

That is, the engagement step 5a of the mudguard 5 made of a highly flexible material such as synthetic rubber is brought into contact with (rests on) the engagement step 4a of the fender 4 from above, thereby positioning it in the vertical direction. Both can be positioned extremely easily by a two-step positioning operation in which the mud guard 5 is prevented from being deformed while doing so, and then the mud guard 5 is moved back and forth. In addition, since the engagement stepped portion 4a of the muzzle guard 5 is brought into abutting engagement with the engagement step portion 5a of the fender 4 from above to prevent deformation and falling off of the mound guard 5, the tightening position of the bolt 6 is not very large. Even if the muzzle guard 5 is made of a highly flexible material, the installation work of the muzzle guard 5 is as easy as the case of a rigid muzzle guard (skirt). can be made higher.

Furthermore, since the concave portion 4b is covered with the scratching plate 7 attached to the outer surface of the fender 4 to ensure the appearance of the fender 4, there is no need to use special cosmetic parts, and the number of parts can be reduced. The increase can be suppressed.

In the embodiment, the lower edge of the mud guard 5 is located at a height near the outer peripheral edge of the front wheel 1, but the mud guard 5 may cover the front wheel 1 to some extent.

As explained above, according to the present invention, since the outer wall of the fender is extended by the muzzle guard made of a highly flexible material, it is not necessary to use a shallow fender, such as in a cab-over vehicle. To prevent splashes from flying around even in a car with a large number of vehicles, without impairing the workability of attaching and detaching the front wheel.

In addition, the engaging stepped portion provided on the mud guard is brought into contact and engaged with the engaging stepped portion formed on the fender from above, and with the two securely positioned and engaged in the vertical direction, the screws are tightened and fixed with bolts. As a result, the installation workability and installation stability of the mudguard can be improved. Furthermore, since the concave part of the fender, to which the head of the bolt is welded, is covered using the tightening plate attached to the outer surface of the fender, the concave part (the head of the bolt) is covered. Therefore, there is no need to provide special cosmetic parts to improve the appearance of the fender, and an increase in the number of parts can be suppressed.
