Description

Description: TECHNICAL FIELD [0001] The present invention relates to a motorcycle, and more particularly, to a motorcycle having a vehicle body cover that covers above a rear wheel.

[Related Art] For example, in some scooter-type motorcycles, the upper part of a rear wheel is covered with a body cover such as a rear cowl or a mudguard. Further, there is a type in which, for example, a tandem seat is provided on an upper portion of the rear cowl so that another person can ride on the rear portion of the seat in addition to the driver.

[Problem to be Solved by the Invention] When the vehicle is driven by such a motorcycle, a phenomenon occurs in which the traveling wind becomes turbulent due to the body cover that covers the upper part of the rear wheel, or a negative pressure occurs behind the body cover. . For this reason, especially when traveling with a passenger on the rear part of the tandem seat, mud and dust, etc., jumped up by the rear wheel on the passenger above the rear wheel may cause turbulent running wind or a negative wind. The pressure causes the air to be sucked into the body, which detracts from a comfortable ride.

The present invention has been made in view of the above circumstances, and has as its object to provide a motorcycle that prevents splashed mud, dust, and the like from hitting a passenger.

Means for Solving the Problems In order to solve the problems described above, according to the present invention, a lower portion of a seat is covered with a rear cowl, and a rear wheel that is vertically swingable with respect to a vehicle body is disposed below the rear cowl. A motorcycle in which a mudguard is provided at a lower rear portion of the rear cowl, the mudguard extending from the upper rear wheel toward the lower rear and extending rearward and downward to cover the rear upper portion of the rear wheel.
A fender portion formed with a U-shaped cross section that has a side wall that is bent forward of the vehicle body on both sides and opens forward of the vehicle body, and is integrally formed on both sides of the fender portion and outside the side wall,
A louver portion is provided, which has a plurality of rectifying passages extending in the front-rear direction and extending in the front-rear direction and formed at positions on the rear surface of the mudguard, and connected to the outlets.

According to the present invention, the fenders have side walls bent toward the front of the vehicle body, so that mud and dust jumped up by the rear wheels can be prevented from hitting the rider. The turbulence that occurs behind the rider when traveling is not only prevented because it takes in and rectifies and flows backward, and since there is no negative pressure, mud and dust splashed by the rear wheel are applied to the rider Can be prevented.

Further, since the louver portions are integrally formed on both sides of the fender portion and outside the side wall, the louver portions can be easily formed without interfering with the rear wheel.

Further, both sides of the fender portion are formed to have a U-shaped cross section having a side wall which is bent forward of the vehicle body and opens forward of the vehicle body, and a louver portion is integrally formed outside the side wall, and the side wall and the louver portion are connected to the fender portion. And the rigidity is improved.

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

1 is a side view of a motorcycle to which the present invention is applied, FIG. 2 is a plan view of the motorcycle, FIG. 3 is a rear view of the motorcycle, FIG. 4 is a front view of a mudguard, and FIG. FIG. 6 is a sectional view taken along the line VI-VI of FIG.

In the figure, reference numeral 1 denotes a scooter as a motorcycle. This scooter 1 is provided with a low-floor, substantially plate-shaped footrest 4 between a handlebar 2 and a tandem seat 3. A leg shield 5 is provided in front of the footrest 4, and the leg shield 5 covers the front of the footrest space. A front wheel 7 supported by a vehicle body via a front fork 6 is located below the leg shield 5.

Further, the front side of the power unit 8 is supported by the vehicle body behind the footrest 4, and the rear side of the power unit 8 is supported by the vehicle body via a rear cushion 9, and can swing. The power unit 8 supports a rear wheel 10.

Rear cowl 11 above power unit 8 and rear wheel 10
The rear cowl 11 is provided with a tandem seat 3, in which a driver sits at a seat front portion 3a and a passenger sits at a seat rear portion 3b. A carrier 12 is attached to an upper rear portion of the rear cowl 11, and a tail lamp 13 is provided to a lower rear portion.

A mud guard 14 is attached to a lower rear end of the rear cowl 11, and the mud guard 14 extends obliquely downward from above the rear wheel 10 so as to cover the rear of the rear wheel 10. The rear cowl 11 of the mudguard 14 has an upper side mounting portion 14a
And the upper rear central mounting portion 14b with mounting screws 15, 16 respectively.
It is fixed and fastened with.

The mudguard 14 has a fender section 140 formed in a U-shaped cross section having a side wall 140a that is bent forward on the both sides and opens forward on the vehicle body, and a fender section 140 on both sides of the fender section 140.
A plurality of rectification passages 18 formed integrally with the outside of the 140b and connected to the outlet 18b extending in the front-rear direction and having the introduction port 18a and extending in the front-rear direction and serving as the rear surface of the mudguard are provided in the vertical direction along the side wall 140b. And a louver section 141.

The mudguard 14 is formed to be wider toward the upper side, and a plurality of straightening passages 18 in the louver portion of the mudguard 14 are formed.
Are formed such that the larger the upper one, the larger the area. Since the upper side of the mudguard 14 is wide, there is a margin for increasing the area of the rectifying passage 18, and the muddy water that has jumped up is difficult to reach the upper side of the mudguard 14. Therefore, while sufficiently securing the fender function (without deteriorating the fender function), the total area of the entire rectifying passage 18 in the louver part 141 can be easily enlarged, and mud and the like jumped up by the rear wheel 10 can be applied to the occupant. The effect of preventing such a situation can be further improved.

Therefore, for example, when a rider sits on the front part 3a of the tandem seat 3 and the passenger sits on the rear part 3b of the tandem seat 3 and travels, traveling wind is taken in from the straightening passage 18 formed in the louver part 141 of the mudguard 14. . The traveling wind is rectified in the rectification passage 18 and is guided to the outlet 18b formed in the louver portion 141 and flows backward.

When the vehicle travels in this manner, since the traveling wind is taken in from the louver portions 141 on both sides of the mudguard 14 by the flow straightening passage 18 and rectified and flows rearward, turbulence generated behind the fender portion 140 when traveling is prevented. In addition, since the pressure does not become negative, it is possible to prevent the mud and dust splashed by the rear wheel by the fender portion 140 from hitting the rider.

Further, since the louver portion 141 is integrally formed on both sides of the fender portion 140 and outside the side wall, the louver portion 141 can be easily formed without interfering with the rear wheel 10.

Furthermore, both sides of the fender portion 140 are formed in a U-shaped cross section having side walls that are bent forward of the vehicle body and open forward of the vehicle body,
The louver portion 141 is integrally formed outside the side wall 140b, and the side wall 140b and the louver portion 141 reinforce the fender portion 140 to improve rigidity.

Further, a louver portion 141 is formed on the mud guard 14 covering the rear wheel 10, and a lead-out port 18b is provided on the rear surface of the louver portion 141, and a rectifying passage 1 that takes in the traveling wind into the lead-out port 18b and guides it straight.
8 is provided, and can be easily formed by processing the mudguard 14.

In addition, without being limited to this embodiment, an outlet can be provided on the rear surface of the rear cowl 11 constituting the vehicle body cover, and a rectifying passage can be provided in the outlet to take in and rectify the traveling wind.

[Effects of the Invention] As described above, according to the present invention, mud and dust jumped up by the rear wheels can be prevented from hitting the rider by the side walls having both sides of the fender bent forward of the vehicle body. In addition, since the traveling wind is taken in from the louver section by the straightening passage and straightened and flowed backward, not only is turbulence generated behind the rider when traveling, but also it does not become negative pressure, so it bounces with the rear wheel Raised mud and dust can be prevented from hitting the rider.

Further, since the louver portions are integrally formed on both sides of the fender portion and outside the side wall, the louver portions can be easily formed without interfering with the rear wheel.

Further, both sides of the fender portion are formed to have a U-shaped cross section having a side wall which is bent forward of the vehicle body and opens forward of the vehicle body, and a louver portion is integrally formed outside the side wall, and the side wall and the louver portion are connected to the fender portion. And the rigidity is improved.
