[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle body structure of a skid steer loader, and more particularly, to an improvement of a fender extending from a vehicle body frame.

[0002]

2. Description of the Related Art A skid steer loader (hereinafter simply referred to as a loader) can perform work on soft ground or in a narrow place with a unique vehicle structure such as a four-wheel drive and skid steering system. At the time of work, there is a problem that the splashed mud easily enters the driver's seat. Moreover, the loader has lift cylinders a for loading and unloading on both sides of the driver's seat because of the body structure, and fenders are indispensable to protect the lift cylinders a from contamination of muddy soil. Is the side wall b of the body frame
At present, a fender d that covers the upper side of the tire c extends along the side of the tire c, and the side end thereof is bent downward for safety considerations (FIG. 2).

[0003]

The above-mentioned loader is provided with optional narrow tires and wide tires in addition to the standard tires so that the loader can be widely applied to work in a narrow place or work requiring strong propulsion. These tires are used at any time depending on the type of cargo handling. For this reason, ideally, it is desirable to adjust the fender according to the mounted tire, or to equip the vehicle with a fender suitable for each tire, but in both cases it is extremely difficult from the viewpoint of productivity Disadvantageous. Therefore, the fender is conventionally provided in a fixed form for the standard tire.

In order for such a fender to exert a mudguard effect, it is necessary to protrude a certain amount upward from the tire, that is, to secure a minimum width W. On the other hand, the line of sight V is blocked by this fender. This makes it difficult to visually recognize the tire (FIG. 3). In other words, the inability to recognize the wheel position based on the tires is a very important safety issue for the driver of the loader who often handles cargo in relatively narrow places. It goes without saying that the same problem occurs when using narrow tires.

An object of the present invention is to make it possible to recognize the wheel position without impairing the mudguard function by improving a fender.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a fender for covering the upper side of a tire extends along a side wall of a vehicle body frame, and the fender has a width aligned with an outer edge of a narrow tire. And a novel configuration is adopted in which the side end portions are bent at a depression angle that does not hinder the visibility of the standard tire.

[0007]

According to the present invention, when used for narrow tires,
With the width of the fender aligned with its outer edge, the wheel position can be recognized properly, while when using standard tires, the tilting and bending formed at the side end of the fender allows the tire to be visually recognized while retaining the mudguard function. Since the range is effectively enlarged, the wheel position can be accurately recognized based on the visual recognition of the tire also in this case.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be specifically described below with reference to FIG. Note that the basic configuration of the loader is not particularly different from that shown in FIG. In the drawing, a driver seat 2 is disposed via a support member at a central upper portion of a body frame 1 having an integrated welding structure, and a side wall 1 of the body frame 1 is provided.
A fender 4 that covers the upper side of the tire 3 and extends along the front-rear direction line of the side wall 1a is provided at the upper end of a. The tire 3a indicated by a solid line in the figure is a narrow tire,
Similarly, a tire 3b indicated by a chain line is a standard tire, and 5 is a lift cylinder disposed immediately above the fender 4.
The side end of the fender 4 is bent 4b at a depression angle that does not hinder the visibility of the standard tire 3b according to the line of sight V passing through the edge 4a, and the width W of the fender 4 determined by the edge 4a. Is configured to be aligned with the outer edge of the narrow tire 3a.

Therefore, when the narrow tire 3a is used, the width W of the fender 4 aligned with the outer edge thereof is set.
(Edge 4a), the wheel position can be accurately recognized. On the other hand, when the standard tire 3b is used, the fender 4
The bend 4b formed at the side end of the standard tire 3b effectively expands the visible range of the standard tire 3b while maintaining the mudguard function (without reducing the width W of the fender 4). The wheel position can be accurately recognized based on the visual recognition. It should be noted that the wide tire (not shown) is wider than the standard tire 3b and does not cause any trouble in the visual recognition of the tire.

[0010]

As described in detail above, the loader fender according to the present invention has a width that matches the outer edge of the narrow tire, and the side end of the fender does not hinder the visibility of the standard tire. /> Because it is bent at the corner, it fully demonstrates the mudguard function of the fender, steadily protects the driver's seat and lift cylinder from contamination on mud, and at the same time, Even during use, safety of cargo handling work can be ensured through accurate recognition of wheel positions.
