JPS5839986Y2 - Front fender structure of motorcycles and tricycles - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a structure around the front fender of a small vehicle having a low footrest, such as a scooter type motorcycle or tricycle.

Vehicles such as scooter-type motorcycles and small tricycles have low floors so that the occupants can place their feet together on the floor and drive the vehicle.

In such a vehicle, when a front cover leg shield is provided at the front of the vehicle body, the front fender faces in front of this, and as is known, the front fender covers the front upper part of the front wheel to the rear lower part of the front wheel, and when steering, the front fender faces the front fender. To avoid interference <In the past, the leg shield was placed at the rear so as not to interfere with the rear part of the fender, so it was difficult to find enough space around the underbody, especially in the front and rear directions, so it was desired to improve the freedom of the underbody. There is.

On the other hand, a system in which the front fender and the leg shield are integrated has been proposed and put into practical use, but according to this, the leg shield part and the front fender part are integrated, so when the front fender part is turned, the front fender part is connected to the front wheel. Therefore, the fender part has to be formed wide to cover the entire steering area, which results in a large fender part, which is not the best in terms of molding. Furthermore, since the fender part and the leg shield part are integrally molded, molding is difficult, the cost is high, and furthermore, the appearance is not the best.

The present invention was developed to rationally solve the conflicting technical propositions of enlarging the footrest floor of this type of vehicle and attaching the fender to the wheel side. It is provided so as to cover the upper part of the front part and the upper part of the middle part, and the function of the rear part of the fender is performed by the leg shield facing above and behind the rear part of the front wheel, thereby avoiding interference between the rear part of the fender and the leg shield, Although it has a fender, the leg shield extends forward, expanding the space in front of the footrest floor, making the length of the vehicle itself the same as before, making it possible to reduce the size and improve the degree of freedom around the suspension. , a motorcycle designed to facilitate fender molding, improve appearance, etc.
To provide a structure around the front fender of an automatic tricycle.

Next, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a side view of the motorcycle 1, with a frame 2 extending diagonally downward and rearward from the rear lower part of the head tube 3, and the frame 2 hanging diagonally rearward and downward from the rear lower part of the herad tube 3. A front part 2a, an intermediate part 2b extending horizontally rearward from the lower end of the front part 2a, a seat post part 2c standing diagonally rearward and upward from the rear end of the front part 2b, and a seat post part 2c extending rearward from the upper end of the front part 2a. It consists of a rear part 2d.

The front lower part of a power unit 6 consisting of an engine 4 and a transmission case 5 is pivotally attached to the rear end of the middle M part 2 b of the frame via a link 1, and a rear wheel 8 is mounted and supported at the rear of the transmission case 5. In addition, the rear part of the transmission case 5 and the rear part of the frame 2
A rear cushion unit 9 is interposed between the rear cushion unit d and the rear cushion unit 9.

A fuel tank 10 is disposed on the upper part of the seat post part 2c, and a seat 11 is attached thereon.The middle part to the upper part of the seat post part 2c and around the fuel tank 100 are covered with a rear cover 12, and the frame is covered with a rear cover 12. rear 2d
and behind the seat and above the rear wheel 8.
covered with.

A front fork 14 is disposed below the head tube 3 via a steering stem 15, the upper end of the stem 15 protrudes above the head tube 3, and a bundle 16 is attached, and a headlight unit 17 is attached to the center of the bundle 16. is installed.

At the lower end of the front fork 14 is a front wheel 1 that serves as a steering wheel.
8, and above this is the front fender 19.
to be placed.

The front fender 19 is formed to cover the front half of the front wheel 18 and does not have a rear half.

The fender 19 has a hole 19a on the upper surface of the rear part through which the lower part of the stem 15 passes, and has an inverted U-shape end section as a whole as shown in FIG. rear wall 19b of hole 19a
It is tied to the lower part of the stem 15, and the rear left and right inner walls of the 7-ender 19 have locking parts 19c.

19c is provided, and this is engaged with the locking protrusions 14b provided on the members 14a, 14a, so that the fender 19 is attached and supported to the front fork 14, and the rear part of the fender 19 attachment support part is missing. There is.

A front cover 20 extending left and right is attached to the front surface of the head tube 3 to support it, the latter half of the head tube is covered with a cover 21, and a floor 22 as a footrest is provided on the middle part of the frame 2. The floor 22 extends left and right, and the floor surface 22a is formed flat in the embodiment.

At the front part of the floor 22, a cover part 22b is formed to stand up vertically in the center, surrounding the frame front part 2a except for the front surface, and on the left and right sides of this cover part 22b, leg shield parts 22c, 2 are provided.
2c is formed to bulge forward.

As shown in FIG. 4, the left and right leg shield parts 22c, 22c are bulged forward in a substantially V-shape, U-shape, etc. and are installed vertically, and the front inner wall 22d of the leg shield part covers the rear left and right sides of the front wheel 18. The rear rear and rear upper parts of the front wheel 18 are covered by a front wall 22e of a cover part 22b, and the inner wall 22d and the front wall 22e constitute the rear half of the front fender 19.

The leg shield parts 22c, 22c are formed so that their positions move forward to the rear left and right of the front wheel 18, so that the front left and right of the floor surface 22a are extended to the lower left and right of the cover part 22b, and the extending part 22f , 22f, the floor surface 22a becomes substantially longer in the front direction.

Since the fender 19 has no rear half while substantially extending the leg shield portion and the floor surface to the front, the fender 19 interferes with the inner walls 22d, 22d of the leg shield portion when the front wheel 18 is steered to the left or right. Never.

Although the illustrated embodiment has been described in detail above, it will be obvious that the front fork 14 may be of a cantilever type, and that the present invention can be easily applied to a tricycle having a low floor.

Further, in the embodiment, the floor and the leg shield are integrated, but they may be molded separately and the leg shield may be assembled separately.

As is clear from the above, according to the present invention, in a motorcycle or tricycle equipped with a low-floor floor and a leg shield, the leg shield is unevenly distributed in the front so that the floor surface extends forward, and the footrest part is It is possible to expand the space in the front and rear direction and improve the degree of freedom around the suspension, and the above functions can be secured and planned for the fender more than before, and the fender and leg shield are separate, and the wheel and Since the fender moves together, a small fender is sufficient, which provides an excellent design and appearance.The fender is also small because there is no rear part, making it easy to mold and contributing to cost reduction. It has many advantages.
