Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an inlet pipe piping structure of an air cleaner in a four-wheel buggy vehicle.

[Conventional technology]

In a four-wheeled buggy with a front cover that has a pair of side covers that cover the left and right front wheels fixed to the vehicle body, the inlet pipe of the air cleaner has the inlet port of the air cleaner depending on the vehicle body structure or the location where the air cleaner is installed. Alternatively, it is arranged inside the front cover or behind the radiator.

[Problems to be solved by the device]

However, when the inlet port of the inlet pipe of the air cleaner is located in the front part of the vehicle such as in the front cover, the four-wheel buggy vehicle has a structure in which the side covers that cover the upper left and right front wheels are located at the high position of the vehicle. There is a problem that mud, water, and the like that are splashed up by the water easily enter through the suction port.

Therefore, in the present invention, in a four-wheel buggy vehicle, even if the inlet port of the inlet pipe of the air cleaner is arranged at the front part of the vehicle body,
It is an object of the present invention to provide an inlet pipe piping structure having a structure in which mud, water, etc. splashed up by a front wheel do not easily enter.

[Means for Solving the Problems]

In order to achieve the above object, the present invention provides a four-wheel buggy vehicle having a front cover fixed to a vehicle body, the front cover having a pair of side covers covering the left and right front wheels. It is composed of an upper plate and a lower plate arranged between the covers, and the inlet port of the inlet pipe of the air cleaner is arranged in a space surrounded by the both side covers and the upper plate and the lower plate. There is.

[Action]

Therefore, the mud and water splashed up by the front wheels are blocked by the side covers, the upper plate and the lower plate and do not directly enter the inlet port of the inlet pipe of the air cleaner.

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows an outline of a four-wheel buggy vehicle, which is a vehicle body frame 1
The lower end of the substantially U-shaped main pipe 2 having an opening at the bottom is connected by an underpipe 3 and a substay 4, and the central portion is reinforced by vertical center pipes 5 and 6 to form a pair of frames. In addition, both frames are connected by a plurality of cross members.

At the front upper part of the main pipe 2, a head pipe 9 is fixedly provided at the front part of a cross member 8 supported by a stay 7.
A steering shaft 12 for steering the front wheels 11, 11 is rotatably supported on the head pipe 9 by steering a bar handle 10.

A seat rail 13 is provided at a rear portion of the main pipe 2 so as to extend rearward of the vehicle body, and a rear end of the seat rail 13 is slanted at a lower portion of the rail 13 so that a seat rail stay 14 is provided between the body frame 1 and
The rear wheels 15 and 15 are suspended on both sides of the lower portion of the seat rail stay 14 while being supported by.

In this vehicle body frame 1, an engine 16 is mounted in a space between a main pipe 2 and an underpipe 3, a radiator 17 is supported in front of it by a main pipe 2 and a center pipe 5, and a seat rail on the left side of the vehicle body. A reserve tank 18 for supplying cooling water to the radiator 17 is fixedly provided on the outer surface of the stay 14.

A resin fuel tank 19 is provided on the upper surface of the main pipe 2 on the rear side of the cross member 8, and a front cover 20 for covering the front portion of the vehicle body is provided in front of the fuel tank 19.

As shown in detail in FIGS. 2 and 3, the front cover 20 includes a pair of left and right side covers 21, 21 and an under cover 22 that is continuously provided below the both side covers 21, 21.
And an upper cover 23 that is continuously provided above both side covers 21 and 21.

The side cover 21 is integrally formed with a fender 21a that covers the front wheels 11 and a side plate 21b that covers the front side surface of the vehicle body. A bracket 21c for attaching an upper cover 23 to the inside of the upper portion of the side plate 21b and an under cover. Brackets 21d for attaching 22 are formed to project at predetermined positions,
Further, a bolt hole 21e for bolting the rear portion to the upper portion of the main pipe 2 is formed in the rear portion of the side plate 21b.

The under cover 22 is provided with a radiator grille 22a for introducing a traveling wind in a front portion thereof, and the radiator grille 2a is provided at an upper portion thereof.
In order to guide the traveling wind introduced from 2a to the radiator 17 and to guide it to the radiator 17, a lateral baffle plate 22b extending to a position above the radiator 17 is provided, and this baffle plate 22b is used for the upper cover 23. It will be the bottom plate. Side plates 22c, 22c are formed so as to extend downward on both sides of the baffle plate 22b.
A bottom plate 22d integrally formed with these is provided between the lower portions of 2c. Further, a projection having a step is formed on both upper sides of the baffle plate 22b, and mounting portions 22e, 22f to the brackets 21d, 21d of the side cover 21 are formed on the projection, and the bottom plate 22d is formed. A bracket 22g for attaching to the main pipe 2 protruding downward is formed at the rear end.

The upper cover 23 which is an upper plate with respect to the baffle plate 22b,
The front part is formed to be slightly bent downward, and a notch 23a for inserting the steering shaft 12 is provided in the rear part.
Further, mounting portions 23b for mounting to the brackets 21c of the side cover 21 are formed on both sides of the lower surface of the upper cover 23.

Then, the side cover 21, the under cover 22, and the upper cover 23 configured as described above have the brackets 21d, 21d of the side cover 21, the mounting portions 22e, 22f of the under cover 22, the brackets 21c, 21c of the side cover 21, The upper cover mounting portions 23b, 23b, 23b are integrally fastened to the 21c by bolts 24 to be integrally assembled, and an opening 25 for introducing traveling air between the front ends of the under cover 22 and the upper cover 23.
Is formed.

As shown in FIG. 3, the front cover 20 integrally assembled in this manner projects a bracket 22g protruding from the rear end of the bottom plate 22d of the under cover 22 onto the front portion of the main pipe 2 via the mount rubber 26. By engaging with the pin 27 provided and inserting the bolt into the bolt hole 21e formed at the rear end of the side cover 21 as shown in FIG. It is attached to the body frame 1.

The front cover 20 attached to the vehicle body frame 1 includes both side covers 21, 21, an upper cover 23, and a baffle plate 2.
The inside of the space surrounded by 2b is shielded from the front wheels 11, 11. In addition, the air cleaner 28 placed at the desired position on the vehicle body
As shown in FIG. 4, an inlet pipe 29 is connected to the inlet pipe 29, and the inlet pipe 29 is provided above the radiator 17 and close to the front of the radiator 17.

Then, the inlet port 29a opened downwardly of the inlet pipe 29 is shielded from the front wheels 11, 11 by the both side covers.
21,21 and upper cover 23 which is upper plate and baffle plate 2 which is lower plate
It is arranged in a space surrounded by 2b.

Thus, by disposing the inlet port 29a of the inlet pipe 29 of the air cleaner 28 in the space surrounded by the both side covers 21, 21, the upper cover 23 and the baffle plate 22b, the front wheel 11 bounces. The raised mud, water, etc. are blocked by both side covers 21, 21, the upper cover 23, and the baffle plate 22b, and the inlet port 29a of the inlet pipe 29 of the air cleaner 28 is blocked.
Will not intrude through.

[Effect of device]

As described above, according to the present invention, the front cover including the pair of side covers that covers the upper left and right front wheels and the upper plate and the lower plate disposed between the side covers are fixed to the vehicle body of the four-wheel buggy vehicle. However, since the inlet port of the inlet pipe of the air cleaner is placed in the space surrounded by the side covers, the upper plate and the lower plate, the mud and water splashed by the front wheels will not be caught on both sides of the front cover. The cover, the upper plate, and the lower plate block the invasion of the inlet pipe from the inlet.
