Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a cargo loading device for a vehicle in which an engine is mounted at the rear between a pair of left and right front steering wheels.

(Prior Art) There have conventionally been four-wheeled vehicles that have an engine mounted at the rear between a pair of left and right steering front wheels. If a large cargo loading space is required for this type of vehicle, it may be possible to use the relatively large space between the front wheels of one vehicle. A problem arises in that it becomes difficult for the wind to hit the vehicle.

(Object of the Invention) The present invention was made in view of the above circumstances, and an object thereof is to provide a cargo loading device for a vehicle that can secure a large cargo loading space without deteriorating engine cooling performance.

(Structure of the Invention) In order to achieve this object, the present invention provides a vehicle in which an engine is mounted behind a pair of left and right steering front wheels.

A cargo loading platform is provided near the front wheels, and a cooling air passage is formed between the cargo loading platform and the front wheels to guide the running air to the engine. The present invention will be described in detail below based on the illustrated embodiments.

(Example) Figures 1 and 2 are a perspective view and a front view of a four-wheeled vehicle for traveling on rough terrain, which is an embodiment of the present invention, Figure 3 is a perspective view of the vehicle body frame, and Figure 4 is a front fender in the center. FIG. 5 is a cross-sectional side view of the front part of the vehicle body, FIG. 5 is a cross-sectional view taken along line v-v, and FIG. 6 is a plan view of the handle stopper.

In these figures, reference numerals 10 and 10 are front steering wheels, and reference numeral 12 (only one of which is shown) is a driving rear wheel, and wide ultra-low pressure tires are mounted on these wheels. The vehicle body frame 14 has two front wheels 1
A pair of front tubes 18 degrees 18 rise upward from the front axle 16 degrees connected at 0.10F, and a main tube 20 extends rearward from the upper end gathering portion of both front tubes. A bracket plate 22 is fixed to the front surface of the gathering part of the front tube plate and the main tube 20. The steering shaft 26 to which the steering handle 24 is fixed is rotatably supported at its upper part by the bracket plate 22 and by a bracket 28 fixed at its lower end by the front axle 16. A handle stopper 30 is fixed to this steering shaft 26, and a handle stopper 30 is fixed to the steering shaft 26.
4, this stopper 30 is connected to the bracket plate 22 at the maximum steering angle.
and restricts its rotation (Fig. 6). Note that 32 is a bracket fixed between the rear surface of this bracket plate 22 and the upper surface of the main tube 20.

A substantially U-shaped king pin bracket 34 is fixed to both ends of the front axle 16, and the knuckle 36 is attached to the king pin 38 here.
(Fig. 5).

A front wheel shaft 40 that supports the front wheel 10 and a knuckle arm 42 are integrally formed on the knuckle 36.

The knuckle arm 42 is connected to a pitman arm 44 fixed to the lower part of the steering shaft 26 by a tie rod 46. Furthermore, when the main wheels 10 are steered at maximum, the knuckle arm 42
comes into contact with the king pin bracket 34 (see imaginary line in FIG. 5).

Reference numeral 50 denotes a cargo loading platform, which, as shown in FIGS. 4 and 5, includes a substantially horizontal ladder-shaped loading section 52 and support legs 54. The rear end of the loading section 52 is fixed to the front tube 18.18, and the lower end of the support foot 54 is fixed to the front axle 16. As shown in FIG. 1.2, this loading section 52 is located at a height near the upper end of both front wheels 10.degree.
It is located between 10 and 10, and its lower part is open to the front. That is, between this loading portion 52 and both front wheels 10.10, there is a cooling air passage 58 that guides running air to the engine 56 located at the rear between both front wheels 10.10.

60 is a front fender. The front fender 60 is integrally formed on the left and right sides, and has a front central portion cut out toward the front so as to surround the loading section 52 from three sides, and a tongue portion protruding downward near the left and right inner edges of the cutout portion. 62 (only one of which is shown) is fixed to arms 64 and 64 that stand upward and outward from the loading section 52.

Further, a support arm 66 bent into a substantially portal shape is fixed to the front tube 18.18 by a bracket 68.68. The lower surface of the front fender 60 is fixed to the bracket 70, 70 and the lower end of the support arm 66. The rear central portion of the fender 60 includes the steering shaft 26 and the front tube 18.
It is notched towards the rear to avoid interference with 18. Therefore, the fender 60 can be easily attached and detached from the front of the steering shaft 26.

In this way, the loading portion 52 of the loading platform 50 is located at a height near the upper edges of both front wheels 10 and 10, lower than the top surface of the fender 60,
Since the front central part of the fender 60 is cut out so as to surround the loading section 52, a large cargo loading space can be secured above the loading section 52.

Further, by opening the lower part toward the front, it is possible to sufficiently guide the running wind to the engine 56.

In FIG. 1, 72 is a rear fender, and 74 is a driver's seat.

In this embodiment, since the loading portion 52 is located at a height near the upper edge of the front wheel 10, the G-forced tire does not hit the loading portion 52 when the front wheel 10 is steered, making it possible to increase the area of the loading portion 52. be. However, the present invention is not limited to this,
The loading platform can be placed at a lower position as long as sufficient wind is guided to the engine.

It may also be provided at the rear of the front tube 18).

In this embodiment, the notch edge at the center of the front of the front fender 60 is located higher than the loading section 52 and surrounds the loading section 52 from three sides, so this notched edge has the function of preventing cargo from falling off. Become.

FIG. 7 is a side view of another embodiment, in which a guard member 76 is attached above the loading platform 50A so as to surround the upper front and upper left and right sides of the loading section 52A. According to this embodiment, not only is it difficult for the cargo to fall in front of the loading section 52A, but also the light does not shine directly on the left and right edges of the front notch of the fender 60, so that the cargo may damage the seventh ender 60. There will be no fear.

(Effects of the Invention) As described above, the present invention provides a cargo loading platform near the left and right front wheels, and forms a traveling wind passage between this and both front wheels. Therefore, it is possible to secure a large cargo loading space without sacrificing engine cooling performance.
