Description

[Detailed Description of the Invention] The purpose of the present invention is to facilitate the disassembly and assembly of the rear axle housing during maintenance and inspection of the rear axle related to the fender mounting structure of a vehicle such as a tractor.

2. Description of the Related Art Some vehicles, such as tractors, have a rear axle housing mounted on both sides of the rear part of the vehicle body through a large-diameter housing part, and a planetary speed reduction device, a brake device, etc. are built into the large-diameter housing part.

In this type of vehicle, the front end of the rear wheel fender is attached to the steps on both sides of the vehicle body, the middle part is attached to the floor cover below the driver's seat, and the rear end is attached to the rear axle housing. If there is a large-diameter housing part on the lateral inner end of the housing, this large-diameter housing part will interfere with the fender, so if you just disconnect the fender and the rear axle housing, the fender will get in the way and the rear axle will interfere with the fender. The housing could not be removed.

Therefore, when maintaining or inspecting the rear axle, it is necessary to remove the fender and open both rear sides of the vehicle body, and then disassemble the rear axle housing. In the case where the cabin frame and safety frame were attached to the vehicle, they had to be completely removed, making the work extremely complicated.

The present invention has been developed to solve these conventional problems, and its feature is that the rear axle housing can be attached and detached from the outside laterally through large-diameter housing parts on both sides of the vehicle body. In a vehicle fender mounting structure in which a part of the rear wheel fender that is freely mounted and is attached to another location on the vehicle body is supported by the rear axle housing, the edge of the fender that faces the rear axle housing. is located radially outward from the outer periphery of the large-diameter housing portion, and a mounting portion on the edge side of the fender is mounted to the rear axle housing via a removable spacer.

Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments.
In the drawings to FIG. 3, reference numeral 1 denotes a tractor body having a transmission case or the like as a structure, and a hydraulic system 2 for raising and lowering a working machine is mounted at the rear of the tractor body 1.

3 is a cabin that covers the driver's seat and the like.

A rear axle housing 4 rotatably holds the rear axle 5, and is provided laterally on both sides of the rear portion of the tractor body 1 via a large-diameter housing portion 6.

The large-diameter housing portion 6 is integral with or separate from the rear axle housing 4, and a planetary reduction gear and a brake device are built into the large-diameter housing portion 6.

7 is a rear wheel detachably attached to the flange portion 8 of the rear axle 5; 9 is a fender placed inside this rear wheel 7;
The front end is attached to a step, the middle part is a floor cover, and the rear end is attached to the rear axle housing 4 via a spacer 10, and a cabin 3 is mounted on the pair of left and right fenders 9.
The rear part of the is placed and fixed.

It goes without saying that the cabin 3 is attached to the tractor body 1 at other locations than the fender 9.

The fender 9 has a mounting portion 11 at the lower rear end thereof, and the mounting portion 11 is located radially outward from the large-diameter housing portion 6.

That is, the distance A between the mounting portion 11 of the fender 9 and the axis of the rear axle 5 is larger than the radius B of the large diameter housing portion 6.

The spacer 10 is removably attached to the rear axle housing 4 together with the check chain bracket 12 by bolts 13, and the mounting plate 14 of the spacer 10 is provided with vibration isolating materials 15, 16, as shown in FIG. bolt 1
7. A mounting portion 11 of the fender 9 is removably fastened via a nut 18 or the like.

The rear end edge 19 of the lower end portion of the fender 9 is also located forward of the large-diameter housing portion 6, similar to the mounting portion 11.

Next, the action will be explained.

During vehicle inspection etc., the rear axle 5 related items, especially the large diameter housing part 6.
When disassembling the planetary reduction gear, brake device, etc. inside the vehicle, first remove the rear wheel 7 from the flange portion 8 of the rear axle 5, and then remove the rear axle 5 from the rear axle housing 4.

Next, after removing the mounting portion 11 of the fender 9 from the spacer 10, the bolts 13 are removed and the spacer 10 and check chain bracket 12 are removed from the rear axle housing 4.

Then, the vicinity of the rear axle housing 4 becomes open, and the large diameter housing part 6 is exposed to the side. Next, remove the mounting bolts and remove the rear axle housing 4 and the large diameter housing part 6.
is removed from the tractor body 1 and pulled out laterally outward.

At this time, the mounting portion 11 and the rear end edge 19 of the fender 9 are positioned radially outward from the large-diameter housing portion 6, so they do not interfere with each other and are moved laterally along their axis. The rear axle housing 4 and the large diameter housing part 6 can be extracted outwardly.

Note that when the rear axle housing 4 is separate from the large diameter housing part 6, a mounting flange part having approximately the same diameter as the large diameter housing part 6 is provided at the inner end of the rear axle housing 4.

In some cases, only a brake device is provided within the large-diameter housing portion 6.

The structure of the spacer 10 is not limited to the embodiment, and may be in the form of a collar, for example.

In the present invention, the edge of the fender facing the rear axle housing is positioned radially outward from the outer periphery of the large-diameter housing portion, and the attachment portion on the edge side of the fender is attached via a removable spacer. Since it is attached to the rear axle housing, even though part of the rear wheel fender attached elsewhere on the vehicle body is supported by the rear axle housing, the entire fender is attached to the vehicle body. By removing the spacer, the rear axle housing can be pulled out laterally outward without interfering with the fender, and the rear axle housing can be easily disassembled and assembled.

In particular, since there is no need to remove the fender, it can be used on vehicles with cabins, safety frames, etc. attached to the fender.
Its practical value is extremely significant.
