Abstract

PURPOSE:To prevent a front wheel driving section from being damaged by pebbles jumping up at bad road running by suspending a cover plate forming an elastic body at the front side lower part of a front wheel side wheel house section. CONSTITUTION:A fender stay 16 that reinforces a front fender panel 11 is provided at the front side lower end of a wheel house section 14 between the front fender 11 and a hood-ridge panel 12. A cover plate 17 forming an elastic body made of such as rubber material is fixed to the perpendicular plate section 16d of this fender stay 16 with a rivet 18. As a result, the pebbles jumping up at bad road running are checked by the cover 17 and a universal joint and such are prevented from being damaged.

Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a drive shaft protection device for a type of vehicle in which the front wheels are driven, such as a FF vehicle (front wheel drive vehicle) or a 4WD vehicle (4 wheel drive vehicle). It is.

Generally speaking, in this type of automobile, as shown in FIG. Even if the steering angle of the front axle 1, which is the steering shaft, changes, power can be transmitted to the front axle 1.

A universal joint 4 is provided. Since this universal joint 4 is exposed inside the wheel house 3, that is, outside the vehicle, it is covered with a bellows-shaped dust boot 5 (Automotive Engineering Handbook, Volume 5, Chapter 1, page 37, published by the Society of Automotive Engineers of Japan, November 1983). reference).

However, the dust boots 5 are made of rubber or the like to deform as the universal joint 4 moves. There was a risk that the dust boot 5 would be hit and damaged, and that muddy water or the like would enter the dust boot 5 and interfere with the smooth movement of the universal joint 4.

In order to solve the troublesome problem of determining the distance between the front and rear wheels, the present invention provides a structure in which the front lower end of the front wheel house of an automobile in which the front axle is driven is provided with a
The drive shaft protection device for an automobile is characterized in that a fender stay connecting a front fender panel and a vehicle body plate is provided, and a cover plate made of an elastic body is vertically provided on the fender stay.

Example Hereinafter, the present invention will be explained based on examples.

1 to 3 are diagrams showing one embodiment of the present invention.

First, to explain the structure, reference numeral 11 in the figure is a front fender panel, 12 is a hood ridge panel, and 13 is a fender protector. These form a wheel house part 14. Inside this wheel house part 14, there is a conventional A front shaft 15 connected to a drive shaft having a universal joint is provided.

and the front lower end portion of this wheel house portion 14.

In other words, on the lower front side of the fender protector 13, there is a fender stay 16 that reinforces the front fender panel 11.
is provided between the front fender panel 11 and the vehicle body panel, here the footridge panel 12. The fender tie 16 is made of a steel plate, has a cross-sectional shape as shown in FIG. 2, and has insertion holes 16b and 16c formed at both ends 16e and 16f of a horizontal plate portion 16a.

And to the vertical plate portion 16d of this fender stay 16.

A cover plate 17 made of an elastic body made of rubber material is fixed with rivets 18 and is provided vertically.

Further, one end 16e of the horizontal plate portion 16a of the fender stay 16 on which the cover plate 17 is vertically installed is inserted into the flange portion 11a at the lower end of the front fender panel 11 through the insertion hole 16b with bolts (not shown). While fixed with a NAND, the other end 16f of the horizontal plate portion 16a is inserted into the insertion hole 16c.
It is fixed to the flange portion 12a at the lower end of the hood ridge panel 12 via bolts and nuts (not shown). Of course, this other end 16f is connected to the hood ridge panel 1.
It can also be attached to a flange portion of a front side member (not shown) joined to the lower end portion of 2.

Next, to explain the effect, when a pebble A is thrown up by the vehicle in front, as shown in Figure 3, when driving on a rough road, etc.
This pebble A is blocked by a cover plate 17 vertically installed on the fender stay 16, and does not directly hit the dust boot 19 covering the universal joint, thereby preventing damage to the dust boot 19. As a result, the smooth movement of the universal joint is maintained.

Furthermore, if there is a step or the like on the ground, the cover plate 17 hits the corner B, but since the cover plate 17 is an elastic body, it deforms elastically in the upward direction shown by the two-dot chain line in FIG. Damage to the cover plate 17 itself is also prevented.

Furthermore, since the cover plate 17 is attached using the fender stay 16, there is no need for a new member for attaching the cover plate 17, and the fender stay 16 can be used effectively, and the cover plate 17 is not required. There is an advantage that the fender stay 16 can be used in common with a vehicle that does not use the vehicle, that is, a vehicle that is not used for driving on rough roads, and a vehicle that requires the cover plate 17.

Further, FIG. 4 shows another embodiment.

The cover plate 27 of this embodiment has a frame portion 27a made of, for example, a rubber material, and a rope portion 27b provided within the frame portion 27a. During running, wind passes through the rope portion 27b, so that the cooling performance of the brakes (not shown) is better than in the first embodiment, and the air resistance during running is also reduced compared to the first embodiment.

By the way, this cover plate 27 cannot block all the splash, but since the splash does not damage the dust boots, there is no problem, and this cover plate 27
Since it is sufficient to block JN stones A, etc., the mesh size is set so that pebbles A cannot pass through.

The other configurations and operations are the same as those in the first embodiment, so their explanations will be omitted.

In addition, if slits are formed in the cover plate 17 of the above embodiment, the same function as the mesh of the above other embodiment can be achieved.

3rd lesson Uυ line of confusion - As explained above, according to this invention.

The cover plate can block pebbles and the like thrown up when driving on rough roads, prevent damage to the dust boots, and maintain smooth movement to the universal joint 1. Since the cover plate is attached to the fender stay that was previously used, there is no need for a new member for attaching the cover plate, and the fender stay can be used effectively, which is a practically beneficial effect.
