Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an improvement of a fuel tank storage section of a traveling vehicle such as a motorcycle or a tricycle.

(Conventional technology) Conventionally, motorcycles and tricycles of the type in which a fuel tank is disposed within a plate-shaped frame that makes up the floor have a plate-shaped frame, so the frame is hollow to ensure rigidity. was forming.

(Problems to be Solved by the Invention) However, in the above-mentioned conventional type of vehicle, it took time and effort to mold the plate-like frame, and the degree of freedom in appearance was low. Therefore, it was necessary to form the frame with a pipe, but if you wanted to install one pipe in the center of the car body and also install a fuel tank, you would need space for the height of the fuel tank and pipe. This increases the amount of protrusion of the low-floor footrest at the center in the width direction of the vehicle, which is disadvantageous in increasing the capacity of the fuel tank.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a vehicle of the type in which a fuel tank is disposed in a low-floor footrest of a motorcycle or tricycle. The goal is to both increase the capacity of the fuel tank and lower the center of gravity of the vehicle.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a low-floor footrest between the front wheels and the rear wheels, and arranges a fuel tank or the like in the footrest. In the traveling vehicle, the fuel tank and the vehicle body frame member are configured separately, and the low-floor footrest is configured with a cylindrical member that extends 19 spaces on the left and right of the frame member located on the lower surface, and , the fuel tank is disposed between the cylindrical members.

(Effect of the above means) According to the above means, since the fuel tank is disposed between the cylindrical members spaced apart on the left and right that constitute the low-floor footrest, the capacity of the fuel tank is increased and , the center of gravity of the vehicle can be lowered.

(Embodiment) Next, a preferred embodiment of the present invention will be described in detail based on the attached drawings.

FIG. 1 is a side view of a tricycle according to the present invention, and FIG. 2 is a plan view thereof.

In this embodiment, a tricycle is shown as the vehicle (1).

The tricycle (1) consists of a front body (2) and a rear body (3).

The front body (two have a low-floor structure similar to the body of a scooter, with a front fender section (4) at the very front, a front section (5) that slopes diagonally backward and downward from the rear of this section, and a front section ( 5) A floor part (6) is provided which extends rearward in a flat manner at a low position from the rear end.The floor part (6) is configured to rest the left and right feet, and the rear part thereof is provided with a floor part (6) that extends flatly to the rear at a low position. Box-shaped raised walls (7) are erected across the vehicle and function as foot guards to prevent the occupant's legs from moving backwards and from interfering with the swinging rear vehicle body (3). .

A front fork (8) is mounted on the front part (5) of the front body (2).
) is erected, a front fork (8) is installed longitudinally on this, and the downwardly extending portion of this (8) supports the single front steering wheel (10). . A bar handle (11) is provided at the upper end of the upwardly extending portion of the post (9) of the fork (8), and a case (12) for storing and supporting a headlight and instruments is provided in this portion. In addition, a seat boss (13) is provided on the center of the raised wall (7) at the rear of the front body (2).
13) A seat (14) for a passenger is placed on top.

The rear subframe (17) is located on the rear lower surface of the front body (2).
extends rearward, and a strut fork (18) is pivotally connected to the rear subframe (17) so as to be swingable about a pin (19). Mounted on the rear fork (18) is a case (21) that houses the engine (20), crankcase, transmission, and deceleration mechanism, and the drive unit (22) includes the two rear drive wheels (23). ,(
23) disposed between. The drive unit (22) is housed within the outline of the drive wheel (23), and is therefore hidden from the side by the drive wheel (23), as shown in broken lines in Figure 1, where (24) is 72 arms, this (24) is also a driving wheel (
It is housed within the outline of 23). Further, (25) a beamer fender member covers the upper parts of the left and right rear wheels (23) and the upper part of the drive unit (22).

A protrusion (332) having a box-shaped cross section and a predetermined width is provided in the front-rear direction at the widthwise central portion of the floor portion (6) of the front vehicle body (2). Footrests (
10B), form (10B), and this part (IH)
.

Therefore, the width of (10[1) is set to a width necessary and sufficient to place the foot on.

In the illustrated example, there is a battery (30) at the front and a fuel tank (30) at the rear in the box-shaped space of the bulging protrusion (132) formed at the center of the footrest (10B), (IOEI).
26), the outside of this (26) is covered, and the cap (27) of the fuel tank (26) is made to protrude above the upper surface (132a) of the protrusion (132).

This protrusion (132) has a structure as shown in the sectional view of FIG. Figure 3 shows the front body (2) made up of a pipe frame (202).
02) are the left and right pipe elements (202a), (202
a) is spaced apart from side to side and extends in the front and back directions, and left and right floor members (20B) and (208) are arranged on top of this, with a space (233) provided between them. This space (2
33) are the left and right pipe elements (202a), (202
Since the space extends below the underline in a), the capacity of the fuel tank accommodated within this space can be increased accordingly. Then cover the bottom of this space (233) with an undercover (2
34) to protect the fuel tank and cover (234).
The left and right ends are tied to the floor members (20B) and (20B), and the elements (202a) and (202a) are sandwiched therebetween.

The upper part of this space (233) is the upper cover (235)
Cover it and hide it from the outside.

In this embodiment, an example in which the present invention is applied to a three-wheeled motor vehicle has been described, but it goes without saying that the present invention can also be applied to a two-wheeled motor vehicle.

(Effects of the Invention) As described in detail above, according to the present invention, the fuel tank, etc. In addition, since the degree of freedom in the placement of the left and right cylindrical members is improved, the installation position of the footrest can be freely selected, and even if the vertical dimensions of the fuel tank are shortened. Since the dimensions in the longitudinal direction can be reduced, the capacity of the fuel tank can be increased, and the center of gravity of the vehicle body can be lowered.

[Brief explanation of drawings]
