Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a front wheel cover device for a scooter.

[Conventional technology and its problems]

The scooter has a mudguard cover above the front wheels. See, for example, JP-A-59-2976. When a bottom link type front hawk is used for the front wheels, another cover is attached to the swing arm portion below the bottom link hawk to improve the appearance. However, if the mudguard cover and the cover for covering the swing arm portion are separately attached in this manner, the number of parts increases, the manufacturing cost increases, and the assembling work becomes troublesome.

Furthermore, since the front end of the mudguard cover is a free end, it easily vibrates. Although it is conceivable to increase the thickness of the cover in order to prevent this vibration, there is a problem that the cover becomes heavy.

[Purpose of the Invention] The invention is to integrally form a cover for covering the upper part of the front wheel for protecting the mud and a cover for covering the swing arm part of the lower part of the bottom link fork into a single cover part, and to perform the assembling work. It is possible to provide a front wheel cover device for a scooter which is simple and can reduce the cost, can reduce the wind resistance due to running, can suppress the vibration of the front end portion without increasing the thickness, and can reduce the weight. To aim.

[Constitution of device]

Hereinafter, a front wheel cover device 1A for a scooter according to the present invention will be described with reference to an embodiment shown in the drawings.

The scooter A straddles the front wheel 2 so as to straddle the front wheel 2 across the lower left and right sides of the front hawk 6 operably supported by the head pipe A ′.
To the left and right to form the ends 6a, 6a (only one of them is shown in the drawing), and the ends 6a, 6a and the ends 9a, 9a of the axle 9 of the front wheel 2 are connected to the swing arm 7. 7 (only one is shown in the drawing), and a cushion is provided between the substantially central portion of the swinging arm 7 and the upper left and right front forks 6b and 6b (only one is shown in the drawing). It is provided with a bottom link type front hawk 6 in which a front wheel 2 is swingable by interposing units 8 and 8 (only one of which is shown in the drawing).

The front wheel cover 1 is attached to the front wheel 2 of the scooter A.

The front wheel cover 1 extends forward and backward so as to cover the upper side of the front wheel 2 and a front cover 1a. The front cover 1 extends laterally from both front sides of the front wheel cover 1 and extends obliquely downward and rearward. The front fork 6 is integrally formed with the cover portions 4 and 4 which cover the outer lower portions of the branch arms 6a and 6a. The upper cover portion 1a and the cover portions 4 and 4 of the front wheel cover 1 are provided with bosses 3 and 5 and bosses 5 and 5, respectively.
5 are provided, and these bosses 3 and 3 and bosses 5 and
A front wheel cover device 1A that is fastened to the front fork 6 of the scooter is formed by passing through 5. The bosses 3 and 3 and the bosses 5 and 5 are provided on the central rear side of the upper cover portion 1a and on the substantially central portion of the cover portions 4 and 4, respectively.

The front hawk 6 is a bottom link type, and the lower ends of the branched arms 6a and 6a that extend to the left and right of the front hawk 6 are
The swing arms 7, 7 are pivotally attached. And swinging arm 7 ・ 7
Is swung by the cushion unit 8 (only one of which is shown in the drawing), so that the front fork 6
Acts as a suspension. Also, the swing arm 7 ・ 7
The axle 9 of the front wheel 2 is attached to the tip of the. Then, the front fork 6 is provided with a stay 10 for connecting the left and right branched arms 6a, 6a to the upper part thereof, and the branched arms 6a, 6a and the cover portion 4 are provided at the lower ends of the branched arms 6a, 6a. Arm pieces 11 and 11 (only one of which is shown in the drawing) provided to connect 4 and 4 are projected.

Thus, the front wheel cover device 1A is passed between the left and right branch arms 6a, 6a from the front side of the scooter A so that the upper cover portion 1a covers the upper part of the front wheel 2, and the bosses 3, 3 are connected to the scooter A. The front hawk 6 is fastened to the stay 10 with screws 12 and 12 (only one of which is shown in the drawing).
Attached to. After that, the cover portions 4 and 4 on both sides are attached to the lower end portion of the front fork 6 to cover them, and the bosses 5 and 5 of the cover portion 4 and 4 are attached to the arm pieces 11 and 11 by screws 13 and 13 (only one is shown in the drawing. There is)), and the cover parts 4 and 4 are branched arms 6a and 6a.
Integrated with.

In this way, when the front wheel cover device 1A is attached to the front fork 6, since the swing arms 7 and 7 are pivotally attached to the lower ends of the branch arms 6a and 6a as described above, the cover portions 4 and 4 are provided. By appropriately adjusting the length, the cover covers the lower ends of the branch arms 6a, 6a, and also covers the swing arms 7, 7.

[Function of device]

The front wheel cover device 1A can cover the upper side of the front wheel 2, and the left and right cover parts 4 and 4 can cover the lower end parts of the left and right arm parts 6a and 6a of the front hawk 6. The front wheel cover 1 in the front wheel cover device 1A is integrally formed with the left and right cover parts 4 in a state where the left and right cover parts 4 spread laterally on both sides of the front end and extend obliquely downward and rearward. Compared to the case where the cover for mudguard and the cover for covering the swinging arm portion below the bottom link fork are separately attached, the number of parts is reduced and the fastening points are reduced.

Further, the line connecting the front end of the front wheel cover 1 and the free ends of the left and right cover parts 4, 4 has a streamlined shape. Therefore, when such a front wheel cover device 1A is mounted on the scooter A for traveling, the rectifying effect is enhanced and the air resistance received during traveling is reduced.

Then, the front end portion of the front wheel cover 1 has the right and left cover portions 4
・ Because it is attached to the front hawk via 4, it is no longer a free end. Therefore, the front end portion of the front wheel cover device 1A has increased rigidity.

Further, in the front wheel cover device 1A, it suffices to pass the upper cover portion 1a of the front wheel cover 1 between the front side of the scooter and the left and right front forks 6 and fasten the upper end and the cover portion 4 with the screws 12 and 13.

[Effect of device]

As described above, in the front wheel cover device for a scooter of the present invention, an upper cover portion that covers the upper portion of the front wheel and extends in the front-rear direction, and side cover portions that extend obliquely rearward and downward from both front portions of the upper cover portion. Since the front wheel cover formed by integrally molding the above-mentioned parts is attached to the front fork with the side cover part covering the lower part of the front fork and the swing arm part, the cover for the mudguard and the bottom link fork. Compared to the case where a cover for covering the lower swing arm portion is attached separately, the number of parts is small and the number of fastening points can be reduced. Therefore, the assembling work becomes easy.

Further, the line connecting the front end of the front wheel cover and the free ends of the left and right cover parts has a streamlined shape. Therefore, when the front wheel cover device including such a front wheel cover is mounted on the scooter for traveling, the rectifying effect is enhanced and the air resistance received during traveling is reduced.

Further, since the front end of the front wheel cover is attached to the front hawk via the left and right cover parts, it is no longer a free end.
Therefore, the rigidity of the front end portion of the front wheel cover is increased, the thickness of the front wheel cover can be reduced, and the weight can be reduced.
