Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a rear fender device for a saddle type vehicle such as an off-road motorcycle.

[Prior Art] In a motorcycle in which a rear wheel is supported by a swing arm that is pivotally supported on a vehicle body in a vertically swingable manner, and a rear cushion unit is installed between the swing arm and the vehicle body, a rear fender that covers the rear wheel is provided. Those provided on the side of the swing arm are known from Japanese Utility Model Publication No. 53-2685 and Japanese Utility Model Publication No. 61-19993.

[Problems to be solved by the invention] By the way, conventionally, since the rear cushion unit is exposed between the swing arm and the vehicle body, for example, if pebbles, mud, sand, etc. hit the rear cushion unit during traveling on an uneven terrain, This may cause damage or decrease the buffer function due to mud clogging.

Therefore, an object of the present invention is to provide a rear fender device for a straddle type vehicle such as an off-road motorcycle, which covers and protects the rear cushion unit and also improves the appearance of the vehicle.

[Means for Solving the Problems] In order to solve the above problems, the present invention provides a rear cushion unit between a swing arm and a vehicle body, in which a rear wheel is supported by a swing arm pivotally supported by the vehicle body in a vertically swingable manner. In a saddle-ride type vehicle in which a rear fender that covers the rear wheels and the swing arm from above and a cover that covers the rear cushion unit from both sides and from the rear are integrally formed to form a rear fender. It is characterized in that it is attached and supported on the swing arm side.

[Operation] Since the rear cushion unit 11 is covered with the cover portion 22,
The cover portion 22 can protect the rear cushion unit 11, and, for example, pebbles, mud, sand, and the like are less likely to hit during traveling on uneven terrain, and therefore damage can be prevented, and deterioration of the cushioning function due to mud clogging can be prevented.

Since the rear cushion unit 11 is covered by the cover portion 22, the appearance of the vehicle is improved.

For example, a rear fender mounted and supported on the swing arm 8 side
If a cover 22 that covers one rear cushion unit 11 located in front of the rear wheel 6 is integrally formed on the front portion of the rear wheel 6, the front portion of the rear fender 20 supported on the swing arm 8 side can be formed. Rear cushion unit cover
The integral molding of 22 makes it possible to obtain a sense of unity with the vehicle body, which contributes to improving the appearance of the vehicle.

[Example] An example will be described below with reference to the accompanying drawings.

In FIG. 1 showing an off-road motorcycle as an example of a saddle-ride type vehicle to which the present invention is applied, 1 is a full cowl that covers an entire body frame equipped with an engine, 2 is a seat,
3 is a steering wheel, 4 is a front wheel, 5 is a front fork, and 6 is a rear wheel. As shown in FIG. 2, the rear wheel 6 is rotatably supported by a rear portion of a swing arm 8 whose front portion is pivotally supported by a rear portion of a vehicle body frame 7 so as to be vertically swingable. A single rear cushion unit 11 is installed between and. The rear cushion unit 11 is composed of a hydraulic damper 12 and a coil spring 13, and is arranged in front of the rear wheel 6 on the vehicle width center line. A chain 16 is mounted on the drive sprocket 14 on the engine side and the driven sprocket 15 on the rear wheel side, and 17 is a chain case.

In the above, the cover portion 22 that covers the rear cushion unit 11 is provided integrally with the rear fender 20 that covers the rear wheel 6. That is, as shown in FIGS. 3 and 4, the rear fender
Reference numeral 20 denotes a cover portion that covers the rear cushion unit 11 from both sides and from the rear of the fender portion 21 that covers the rear wheel 6 from above.
It is made of resin that 22 is integrally molded. Then, the partition plate portion 23 between the fender portion 21 and the cover portion 22 is formed inside, and mounting pieces 24, 25 extending in the front-rear direction are formed on the lower sides of both side portions of the rear fender 20, and further from the rear portion of one mounting piece 24. A chain guard portion 26 extending downward is vertically provided.

Next, the mounting of the rear fender 20 will be described.

First, the swing arm 8 is a rear fork having left and right rectangular fork pipes 9, 9 as shown in FIG. 5, one fork pipe 9 is housed in a chain case 17, and the other fork pipe 9 is a dummy case 18. It is stored inside. This dummy case 18 has a U-shaped cross-section with an open inner side, similar to the chain case 17, and the front and rear stays of the two fork pipes 9 and 9 are vertically long as shown in FIG. 19 and 19 are provided respectively, and each stay 19 has a U-shaped cross section similar to the inner surface shape of both cases 17 and 18, and the outer surface of both fork pipes 9 and 9 as shown in FIG. It is fixed by welding. A chain case 17 and a dummy case 18 are screwed to the upper and lower sides of the stays 19 ,.

Then, both mounting pieces 24 and 25 of the rear fender 20 are overlapped on the upper surfaces of the chain case 17 and the dummy case 18 and fixed to the stay 19 with screws in common, and the rear fender 20 is attached to the swing arm 8.
The fender portion 21 covers the rear wheel 6 from above, and the front cover portion 22 covers the rear cushion unit 11 from both sides and from the rear. In addition, a chain guard 26 is provided on one side of the front of the rear wheel 6.
Is located, thereby preventing interference with the chain 16 and a chain guide in a portion along the rotation locus of the rear wheel 6 on the inner open surface of the chain case 17. Further, a protrusion 27a on the lower surface of the chain case 17 is fitted in a groove 26a at the lower edge of the chain guard portion 26 to prevent the chain guard portion 26 from stabilizing.

As described above, since the cover portion 22 for covering the front rear cushion unit 11 is provided integrally with the rear fender 20 provided on the swing arm 8 side, the rear cushion unit 11 can be protected and pebbles, mud, sand, etc. The cushioning function is prevented from being deteriorated due to damage and clogging, and the appearance is improved because the rear cushion unit 11 is not exposed. Especially, although the rear fender 20 is supported on the swing arm 8 side, the front rear cushion unit By integrally molding the cover portion 22 for a vehicle, as shown in FIG. 1, a sense of unity with the body line of the full cowl 1 of the vehicle body is provided, and the appearance of the motorcycle is enhanced.

Although the embodiment describes the off-road motorcycle, the present invention is also applicable to other saddle-ride type vehicles such as off-road motorcycles.

[Advantages of the Invention] As is apparent from the above description, according to the rear fender device for a saddle-ride type vehicle according to the present invention, the fender portion that covers the rear wheel and the swing arm from above, and the rear cushion unit from both sides and from behind are covered. Since the rear fender is formed by integrally molding with the cover part and this rear fender is mounted and supported on the swing arm side, the rear cushion unit can be protected and the buffer function deterioration due to damage and mud clogging can be prevented and the appearance of the vehicle can be improved. Can be improved.
