DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rear fender of an industrial vehicle such as a wheel loader which is located in an opening / closing path of an engine room door of an industrial vehicle and covers a rear wheel tire to perform a mudguard function.

[0002]

2. Description of the Related Art As an industrial vehicle, there is known a construction work machine called a wheel loader which is equipped with a work machine for scooping earth and sand on a self-propelled vehicle running on wheels. In this wheel loader, an engine room is installed at a position where a rear wheel tire called a rear tire is located, and an engine room door is provided on a side of the engine room.
Wheel loaders have these structural features not found in ordinary automobiles. For this reason, in the wheel loader, it is necessary to open and close the engine room door, and a cover that functions as a mudguard on the rear wheel side, which is called a rear fender, cannot be provided easily as in a general automobile. On the other hand, the wheel loader is also characterized in that it is used in a relatively remote place such as a gravel pit. Under these circumstances, rear fenders that act as mudguards for the rear wheels were not provided on at least the standard model. Some wheel loaders were provided with such a rear fender, but were not of a normal size that could cover the rear tire as widely as ordinary cars. This is because, in the wheel loader, the engine room is provided at the rear position where the rear tire is located as described above, so that the rear fender needs to be small so as not to obstruct the opening and closing of the engine room door. Wheel loaders without such rear fenders or with very small ones were not so problematic as long as they were used at specific work sites where traffic was low, such as gravel pits. . However, in recent years, the number of uses not only in remote places but also in the vicinity of houses, such as for snow removal, has increased. In such a case, if the road conditions are not good, splashes of muddy water and splashes to the neighborhood are widespread, so that not only the own vehicle is soiled but also nearby traveling vehicles, pedestrians and the like are inevitably inconvenienced. D) Under such circumstances, recently, a wheel loader has been proposed that has a large rear fender that can widely cover the rear tire and that is devised so that opening and closing of the engine compartment door does not occur. . As an example of such a proposal, Japanese Utility Model Laid-Open No. 3-130775 and Japanese Utility Model Laid-Open No. 3-13 are disclosed.
No. 0776 can be mentioned.

[0003] The former technology disclosed in Japanese Utility Model Application Laid-Open No. 3-130775 discloses "a rear fender of an industrial vehicle such as a wheel loader provided so as to be located in an opening / closing path of an engine room door is provided with an engine room. The front part which is not located in the opening and closing path of the door and the rear part which is located in the opening and closing path are divided into two parts, the front end of the rear part is swingably attached to the vehicle body side and the rear end of the rear part is the body The rear fender can be swung up to a position where it does not interfere with the opening and closing of the engine room door by releasing the lock when the engine room door is opened. I did it. " In addition, the latter Kaikaihei 3
The technology described in Japanese Unexamined Patent Publication No. 130776 discloses a technique for “a rear fender of an industrial vehicle such as a wheel loader provided to be located in an opening / closing path of an engine room door.
The rear fender is divided into two parts: a front part that is not located in the opening and closing path of the engine compartment door, and a rear part that is located in the opening and closing path. Both ends of the rear part are attached to the vehicle body so as to be able to move up and down. To release the lock when the engine compartment door is opened, so that the engine compartment door can be lowered to a position where it does not interfere with the opening and closing of the door. "

[0004]

In each of these prior arts, the operation of displacing the rear fender to a position that does not hinder the opening and closing of the engine room door when opening and closing the engine room door, and the operation of displacing the body of the rear fender. It is necessary to always perform two types of operations of unlocking and locking the mounting portion to the rear fender, and the operation of the rear fender is complicated. On the other hand, since the rear fender is subjected to vibration and impact during the operation of the wheel loader, it is originally desirable that the rear fender be securely fixed to the vehicle body. However,
In such conventional technology, every time the engine room door is opened and closed, an operation of unlocking and locking the attachment portion of the rear fender to the vehicle body is required. There is a possibility that rattling may occur at the mounting portion of the rear fender to the vehicle body, and there is a problem in terms of mounting structure and durability. These problems are not limited to wheel loaders.In the case of an industrial vehicle in which an engine room is installed at a position where a rear tire is provided and an engine room door is provided on the side of this engine room, the rear fender can be opened and closed by opening and closing the engine room door. This is a common problem when trying to attach to a route.

An object of the present invention is to solve such a problem which is observed in a conventional rear fender of an industrial vehicle. The technical problem is that the operation for opening and closing an engine room door can be easily performed and the durability is excellent. An object of the present invention is to provide a rear fender for an industrial vehicle having an attachment structure.

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to provide an industrial vehicle which is mounted on an opening / closing path of an engine room door on the side of an engine room and covers a tire of a rear wheel so as to perform a mudguard function. In the rear fender of the vehicle, at least a portion located in the opening / closing path of the engine room door is configured by an elastic fender made of an elastic material, and the elastic fender is curved in an arc shape in the same direction as the tire of the rear wheel. By attaching both sides of the fender to a place outside the engine room door so that at least one side can swing freely, it performs a click motion operation that reverses and deforms when a pressing force is applied and maintains the deformed state It does not disturb the opening and closing of the engine room door when it is formed by deforming it by inverting it by applying the pressing force Is achieved by a rear fender of industrial vehicle as described in claim 1., wherein the "possible to be able to hold the shape state.

Since the rear fender of the present invention has the above-described structure, when an operator applies a pressing force to the elastic fender, at least one side of the elastic fender starts to deform while swinging, When the deformation progresses to a certain point, the motion is reversed and deformed to perform a click motion operation, and the deformed state is maintained in the inverted state. At this time, the elastic fender constituting the rear fender maintains a deformed state that does not hinder the opening and closing of the engine room door, so that the engine room door can be opened and closed. In the case where the rear fender of the present invention is embodied, when the configuration of claim 6 of the claims is employed, when the pressing force is applied, only one side of the elastic fender easily swings in the reverse direction. Then, after the inversion, it is deformed into a substantially S-shape, and the deformed state is maintained. Claim 7 of the claims
When the configuration is adopted, both sides of the elastic fender are likely to swing in the inversion direction, and after the inversion, the elastic fender is deformed into a substantially arc shape to maintain the deformed state. In the case where the rear fender of the present invention is embodied, when the configuration of claim 8 or claim 9 is employed, one side of the elastic fender may be detachable via a detachable tool. Because it is attached, by removing the attachment / detachment and displacing the elastic fender to a place where it does not interfere, not only can the engine room door be opened and closed, but also the worker can easily access the engine room .

In each of the rear fenders of the first to fifth embodiments of the present invention, the engine room 3 is installed at a position where the rear tire is located, as in the above-described conventional technology.
In the industrial vehicle having the engine room door 4 provided on the side of the engine room door, the engine is installed so as to be located in the opening and closing path of the engine room door 4, and covers the rear tire 1c so as to perform a mudguard function. , The same as the prior art.

First, an overall image of a standard wheel loader will be described with reference to FIG. 1. The wheel loader 1 is equipped with a work machine 1a for scooping soil and the like on a self-propelled body running on wheels. It is an industrial vehicle for construction work that loads earth and sand. As shown in FIG. 1, a frame 6 that forms a skeleton of a vehicle body is provided at a bottom portion, and the frame 6 includes a bucket 1.
b is installed at the front part, and the engine room 3 is located at the position where the rear tire 1c at the rear of the vehicle body is located.
An engine room building for forming the vehicle is provided, and an operator cab 2 is provided in the center of the vehicle body. In an engine room 3 formed by an engine room building, an engine and its related devices are housed, and an engine room door 4 for opening and closing is provided at a side portion for inspection and maintenance thereof. When working with the wheel loader 1, the operator operates the operation machine 1a by operating the operation lever in the cab 2 to scoop up the soil and the like with the bucket 1b, carry it to a carrier such as a dump truck, and load it. Wheel loader 1
Is usually used for snow removal in snowy areas,
An attachment for plowing, which is called a plow, is attached to the plow. When snow removal is performed, the plow is replaced with the bucket 1b.

Next, a description will be given of a rear fender according to a first embodiment of the present invention with reference to FIGS. 1 to 3. Reference numeral 5 denotes a small fender provided so as not to be located in the opening / closing path of the engine room door 4, and reference numeral 7 denotes an elastic fender. The elastic fender 10 which is made of a material and is provided in the opening / closing path of the engine room door 4 includes an angle material 10a and a flat bar material 10b.
And a rear bracket 11 connected to each other by a hinge 12 and fixed to a side portion of the frame 6 by appropriate means such as welding or bolt fastening. Reference numeral 11 denotes a front bracket formed of a plate-like member. The rear fender of the present embodiment is broadly classified so that the small fender 5 and the elastic fender 7 can widely cover the rear tire 1c, which is the rear wheel tire. The small fender 5 is attached adjacent to and behind the driver's cab 2 at a predetermined interval from the rear tire 1c,
The front end of the front bracket 11 is attached to the rear end with bolts 16. The elastic fender 7 is attached to the rear end of the bracket 11 with bolts 17 so as to be sandwiched by the plate 14, and is integrally connected to the small fender 5 via the front bracket 11. Also,
The rear end of the elastic fender 7 is attached to the flat bar member 10b of the rear bracket 10 with a bolt 15 so as to be sandwiched by the plate 13.

When the both sides of the elastic fender 7 are attached to locations outside the engine compartment door, the elastic fender 7 is bent in a substantially arc shape so as to substantially follow the curved surface at a predetermined interval from the rear tire 1c. Thus, the rear fender is formed so that when the pressing force is applied, the rear fender is inverted and deformed to maintain the deformed state. When the rear fender is inverted and deformed by applying a pressing force to the elastic body fender 7, the rear fender can maintain a deformed state that does not hinder the opening and closing of the engine room door 4. In other words,
The rear fender is displaced outside the opening / closing path of the engine room door 4 due to the deformation of the elastic body fender 7 at the time of inversion. The operation in which the elastic body is inverted and deformed by the application of the pressing force and maintains the deformed state is generally called a click motion, and such a phenomenon is also called a jump buckling phenomenon. In order to form the rear fender of this embodiment so as to perform such a click motion operation, a portion located in the opening / closing path of the engine room door 4 is constituted by an elastic fender 7 made of an elastic material. Both ends of the elastic fender 7 are attached to locations outside the engine room door 4 in a state of being curved in an arc shape. In that case,
To ensure that the rear fender performs the click motion operation reliably and smoothly, the rear end of the elastic fender 7 is
In particular, it is mounted via a rear bracket 10 which is rotatably connected with a hinge 12. That is, by attaching the attachment portion of the elastic fender 7 via the rear bracket 10 so as to be rotatable, the attachment portion is attached so as to be swingable, in other words, so as to be easier to swing as compared with the case where the attachment is simply performed. As a result, the elastic fender 7 can be turned over smoothly and surely in a deformed state at the time of the turning over, and the end of the elastic fender 7 can be prevented from being locally deformed.

The elastic fender 7 may be made of any metal or nonmetal as long as it is made of an elastic material. In this embodiment, the elastic fender 7 is made of a nonmetal such as rubber or synthetic resin. It is made of an elastic material. Therefore, it is lightweight and easy to handle as compared with the case where it is formed of a metal material. Also,
Since the plate material made of such an elastic material is a non-brittle body, it is not damaged by vibration or impact during operation of the wheel loader. When the elastic fender 7 is made of a nonmetallic elastic material such as rubber or synthetic resin, in this embodiment, the elastic fender 7 is made of a plate material whose thickness and material do not change so as to facilitate manufacture. As shown in FIGS. 4 and 5, a corrugated plate 7a having a mountain-shaped convex portion is joined to one surface of a flat plate 7b to form a hollow portion at the mountain portion, and the hollow portion is formed in the longitudinal direction of the elastic fender 7. You may make it extend toward.
When the elastic body fender 7 has such a structure, when the elastic body fender 7 is mounted in a state of being curved in a substantially circular arc shape, a hollow portion is provided in the direction of the circular arc of the substantially circular arc surface, and the rigidity of the elastic body is particularly improved. Since the strength can be increased at the hollow portion, the elastic fender 7 having an appropriate elastic force can be obtained even if the corrugated plate 7a or the flat plate 7b is thinned. Further, a core material 8 having moderate elasticity and rigidity may be attached to the hollow portion formed in the elastic body fender 7 as shown in FIGS. By selecting the material of the core member 8 and adjusting the elastic force at the time of mounting, the elastic fender 7 can be given an appropriate elasticity. In the case of manufacturing the rear fender of this embodiment, naturally, the elastic body fender 7 allows the operator to perform a reversing operation by human power, and generates a force (vibration generated by shock or vibration during operation of the wheel loader 1). The elastic fender 7 is designed so as not to be substantially deformed by the force based on the acceleration due to the shock or vibration and the own weight). Therefore, the material and structure of the elastic fender 7 are appropriately adjusted using the above-described means. And its dimensions and mounting method are appropriately selected. As shown in FIGS. 4 and 5, when the elastic core material 8 is attached to the hollow portion of the elastic fender 7, as described above, the elastic fender 7 is appropriately adjusted by adjusting the elastic force of the core material 8. Since elasticity can be provided, the elastic fender 7 meeting such conditions can be easily obtained.

A rear fender according to a first embodiment of the present invention comprises:
Since the operator has the structure described above, when the operator pushes the finger portion shown in FIG. 2 in order to flip the elastic fender 7, the rear bracket 10 of the elastic fender 7 is pressed.
The side swings around the hinge 12 and starts deforming. When the deformation proceeds to a point where the deformation exceeds the neutral point, a jumping buckling phenomenon occurs and the reversal occurs. Deform and maintain the deformed state. In this case, since the elastic body fender 7 is mounted so that only one side is swingable in this embodiment, the elastic body fender 7 is deformed into a substantially S-shape as shown by a chain line in FIG. I do. As a result, the portion of the elastic fender 7 constituting the rear fender is displaced out of the opening / closing path of the engine room door 4,
The engine room door 4 can be opened and closed, and daily inspection and maintenance work in the engine room 3 can be performed. As described above, the rear fender of this embodiment is used when opening and closing the engine room door 4 for daily inspection and maintenance work.
Unlike the conventional one, it is sufficient to perform only the operation of displacing to the position that does not obstruct the opening and closing or the original position, and it is not necessary to perform the operation of unlocking or locking the mounting part to the vehicle body, In addition, since there are no movable parts other than the hinge 12, the operation can be performed easily, and even when used for a long period of time, the rear fender does not rattle at the attachment part to the vehicle body. Therefore, according to this embodiment, the rear fender of the industrial vehicle having the mounting structure with excellent durability can be obtained in which the operation for opening and closing the engine room door 4 can be easily performed. In the present embodiment, the rear end of the elastic fender 7 is particularly mounted so as to be swingable by the rear bracket 10 having the hinge 12, but depending on the arrangement of the engine room door 4, the front end of the elastic fender 7 may be provided. The part may be swingably mounted by such a bracket.

The rear fender of the second embodiment of the present invention will be described with reference to FIGS. 6 and 7. The rear fender of the second embodiment is the same as the rear fender of the first embodiment of the present invention. Is divided into a front piece 11a and a rear piece 11b and connected by a hinge 18, so that the front end of the elastic fender 7 is also swingably mounted. It is not different from that of the chemical example. The rear fender of the second embodiment is mounted so that not only the rear end but also the front end of the elastic fender can swing freely.
It is easy to swing in the reverse direction at both ends, as a result,
After the inversion, it is deformed into a substantially arc shape as shown by a chain line in FIG. 7 and the deformed state is maintained. The rear fender of the second embodiment is deformed into a substantially arc shape after inversion, and is significantly displaced downward from that of the first embodiment, as apparent from FIG. 7 in comparison with FIG. Even if the position to be displaced accordingly fluctuates slightly, it can always be reliably displaced outside the opening / closing path of the engine room door 4. In the above embodiments of the present invention, the hinges 12 and 18 are used as means for attaching the elastic fender 7 so as to be swingable.
However, any type of mounting means that can be mounted so as to be more easily oscillated than when the elastic fender 7 is simply mounted, and that enables the fender 7 to be turned over smoothly can be used. Does not matter.

The rear fender of the third embodiment of the present invention will be described with reference to FIGS. 8 to 12. The rear fender of the third embodiment is the same as the rear fender of the first embodiment of the present invention. When the front end of the elastic fender 7 is attached to the front bracket 11 through the attachment / detachment tool of the catch assembly operation, the front end of the elastic fender 7 is made detachable. Then, it is not different from that of the first embodiment.
The attachment / detachment tool of the catch assembly operation uses a mechanism similar to a clasp commonly used for a travel bag, a basket, or the like. Therefore, the attachment / detachment tool of the catch assembly operation will be described in detail.
a is a handle of a catch assembly which is rotatably mounted on a plate 24 serving as a mounting board via a bracket, 20b.
Is a lever having a rear end pivotally attached to the handle 1a, 20c is a latch having a hook insertion hole, 21 is a hook for inserting the hook into the hook insertion hole of the latch 20c, and 23 is a cross-sectional key serving as a mounting board for the hook 21. Angled material, 24,
Reference numeral 25 denotes upper and lower plates for holding the elastic fender 7. Catch assembly can be roughly divided into handle 2
0a, a lever 20b and a latch 20c. As shown in FIG. 10, the lever 20b is formed by bending a plate into a substantially U-shaped cross-section and axially attaching the lever 20b to sandwich the handle 20a at both ends. A latch 20c is fitted into the front end of the lever 20b, and is urged by a spring provided in the central space of the lever 20b. The base of the hook 21 is fixed to a horizontal piece of the angle member 23 with a bolt 22, and a hook-side stopper 27 is attached to a vertical piece. The angle member 23 is attached to the front bracket 11. Upper and lower plates 2
