Description

[Detailed Description of the Invention] The present invention relates to a rear fender for a tractor that tows a semi-trailer.

A tractor towing a semi-trailer has a coupler 1 on the hoop near the rear axle, as shown in Figure 1.
is arranged, and the lower surface of the front end of the semi-trailer is placed on the upper surface of the connecting plate 2 of the coupler 1 to be attached. Since the vehicle height in this installed state is regulated by law (3.8 m or less), the installation height of the coupler 1 is made to be as low as possible.

On the other hand, a rear fender 4 is provided to cover the rear wheels 3 in order to prevent the coupler 1 and the semi-trailer from being contaminated by mud and splashes thrown up by the rear wheels 3.

However, if the installation height of the coupler 1 is lowered as described above, when a semi-trailer is coupled to the coupler 1, the lower surface of the front end of the semi-trailer will be lower than the rear fender 4.
easy to interfere with. For this reason, the center portion 5 of the rear fender 4 is made of an elastic material and is fixed to the front and rear fenders with bolts or the like, but despite this, there has been a problem in that the fender 4 is damaged due to interference from above and below.

The present invention is intended to solve the above-mentioned problems.The rear fender is composed of front and rear fixed fenders and a central movable fender that is movable by an elastic body. It is an object of the present invention to provide a rear fender for a tractor that can be easily displaced elastically.

Hereinafter, embodiments will be described based on the drawings.

In Figure 2, rear wheels (indicated by two-dot chain lines) 3
The front fender 7 is attached to the stay 8 on the front frame 6.
Further, a rear fender 9 is fixed to the frame 6 behind the rear wheel 3 via a stay 10.

An arc-shaped central movable fender 11 is disposed above the rear wheel 3, and the rear edge of the central movable fender 11 is connected to the support portion 1 of the upper edge of the rear fender 9.
2 with bolts 13, and the front edge is fixed with bolts 16 by holding one end of the elastic plate 14 with a counterweight 17 as shown in FIG.
The other end of the elastic plate 14 is attached to and supported by a support portion 15 on the upper edge of the front fender 7 with bolts 16 and a stop plate 18. This central movable fender 11 is made of, for example, FRP, but is not limited to this.

The elastic plate 14 is made by folding a rubber plate into a U-shaped groove, for example, and connects the lower surface of the front end of the central movable fender 11 and the upper edge of the front fender 7 so that the U-shaped opening faces the upper surface of the front fender 7. It is clamped between the support part 15 of the. Then, a stopper rubber 19 is attached to the contact plate 18 of the upper edge support portion 15 of the front fender 7.
is fixedly installed.

Further, the location where the elastic plate 14 is disposed is not limited to the support portion 15 of the front fender 7, but may also be provided at the support portion 12 of the rear fender 9. In that case, the central movable fender 11 is located on the front fender 7. Support part 15
is fixed by bolts 13. Alternatively, the support parts 15 and 12 of the front and rear fenders 7 and 9
The elastic plate 14 may be provided on both sides.

With this structure, as shown by the two-dot chain line in Fig. 1, when the semitrailer is initially connected, the lower surface of the front end of the semitrailer contacts the inclined surface of the connecting plate 2, and the lower surface of the front end is in the center. When the central movable fender 11 is at a position lower than the upper surface of the movable fender 11, the central movable fender 11 is pressed downward by the lower surface of the front end of the semi-trailer, but the U-shaped movable fender 11 provided on the support portion 15 of the front fender 7 shown in FIG. Groove-shaped elastic plate 1
Together with the deformation of 4, the central movable fender 11 deforms as shown by the two-dot chain line, thereby being able to escape from the lower surface of the front end of the semi-trailer. When the connection is completed, the central movable fender 11 and the elastic plate 14 return to their original states by their respective elastic forces.

Furthermore, when the semitrailer is detached from the tractor, the central movable fender 11 operates in the same manner as described above. Furthermore, since the space between the central movable fender 11 and the front fender 7 is covered with an elastic plate 14, mud and
Droplets are not scattered to the outside, and since a counterweight 17 is attached to the front edge of the central movable fender 11, rattling during driving can be suppressed.

As explained above, according to the present invention, the central movable fender is supported by the front and rear fixed fenders via elastic plates, making it easy to move up and down. Furthermore, even if the rear wheel hits the central movable fender when the tractor is traveling on a rough road, the central movable fender can deform and escape upwards, preventing rear wheel collisions. It will not be damaged by.

In addition, in this invention, an elastic body made of a rubber plate is bent into a U shape, and one end of the elastic body is attached to a central movable fender.
Since the other ends are supported by the fixed fenders, the central movable fender can be movably supported despite the simple structure, and no noise is generated due to vibrations during running.

In addition, since a counterweight is attached to the central movable fender, it is possible to suppress the rattling of the central movable fender during driving, thereby preventing the central movable fender from colliding with the bottom of the semi-trailer, thereby preventing a collision. The accompanying noise generation can be reduced.

In addition, since the stopper rubber is fixed to the front fender facing the movable fender, even if the U-shaped elastic plate deforms and the lower surface of the front end of the movable fender collides, the stopper rubber will absorb the impact. This prevents cracks from forming in the movable fender made of plastic, etc., suppresses the occurrence of collision noise, and also prevents the bolts used to secure the U-shaped elastic body from hitting the opposing surface. You can also do that.
