JP 2013-244877 A

The side stand is retracted while the vehicle is running. In this state, the ground surface of the side stand faces rearward. In the conventional configuration, there are cases where muddy water splashed during running bounces off the ground contact surface of the side stand and reaches the intake port of the air cleaner located above the ground contact surface.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a straddle-type vehicle capable of preventing muddy water bounced off the ground contact surface of a side stand from reaching an intake port of an air cleaner while the vehicle is running.

As means for solving the above problems, a straddle-type vehicle according to one aspect includes a vehicle body (11), an exterior cover (C) covering the vehicle body (11), and a retracted position and a standing position by the vehicle body (11). a side stand (20) rotatably supported between the side stand (20) and having a ground contact surface (23a) in contact with the ground when in the standing position; The exterior cover (C) includes an undercover (50) covering the vehicle body (11) from below and a side cover (40) erected from a side edge of the undercover (50). The under cover (50) and the side cover (40) form an opening (O) through which part of the side stand (20) passes, and the exterior cover (C) includes the side stand (20 ) is located above the ground contact surface (23a) and below the intake port (18a) when the air conditioner is in the retracted position. overlaps the ground contact surface (23a) when the side stand (20) is in the retracted position.

According to the above aspect, the protection wall provided on the exterior cover is positioned above the ground contact surface and below the intake port of the air cleaner. Furthermore, the protection wall overlaps the ground surface when viewed from below. For this reason, even if muddy water hits the ground surface and bounces upward while the vehicle is running, the muddy water can be received by the protective wall. Therefore, it is possible to prevent muddy water from reaching the intake port located above the ground contact surface.

Here, the protection wall (54) may be formed in the undercover (50).

In this case, the protection wall can be provided at a position close to the ground contact surface of the side stand by forming the protection wall on the lowermost undercover of the exterior covers. Therefore, the muddy water bounced off the ground contact surface can be more reliably received by the protective wall.

Further, the protection wall (54) may have a linear shape extending in the longitudinal direction of the vehicle.

In this case, it is possible to prevent the protective wall from obstructing the flow of the air that has flowed into the exterior cover while the vehicle is running and is discharged to the rear of the straddle-type vehicle. Therefore, air resistance during running can be reduced.

Further, the protection wall (54) may be positioned on a straight line connecting the ground contact surface (23a) and the intake port (18a) when the side stand (20) is in the retracted position.

In this case, the protective wall can receive the muddy water that bounces off the ground surface and travels straight toward the intake port. Therefore, it is possible to more effectively prevent muddy water from reaching the intake port.

According to the aspect of the present invention, it is possible to provide a straddle-type vehicle that can prevent muddy water bounced off the ground contact surface of the side stand from reaching the intake port of the air cleaner while the vehicle is running.

A seat 5 on which passengers including the driver are seated is supported above the rear cover 9 .

The undercover 50 covers the lower portion of the vehicle body. The pair of side covers 40 are erected upward from left and right side edges of the under cover 50 . FIG. 2 is a left side view showing a state in which the side cover 40 and the undercover 50 are combined. 3 is a left side view of the undercover 50 alone, and FIG. 4 is a top view of the undercover 50 alone. As shown in FIGS. 3 and 4 , the undercover 50 has a bottom plate portion 51 , a left side wall portion 52 and a right side wall portion 53 . The bottom plate portion 51 extends along the front-rear direction and the left-right direction. The left side wall portion 52 extends upward from the left edge portion of the bottom plate portion 51 , and the right side wall portion 53 extends upward from the right edge portion of the bottom plate portion 51 .

As shown in FIG. 3, the vertical dimension of the left side wall portion 52 increases toward the rear. The left side wall portion 52 is formed with a notch portion 52a (first notch portion) that opens upward in a side view. The notch 52a is formed so as to avoid the side stand 20 and surrounding structures. A pair of side covers 40 are attached to the left side wall portion 52 and the right side wall portion 53, respectively. The left side cover 40 and the right side cover 40 may have different shapes. The shape, arrangement, etc. of the left side cover 40 (the side on which the side stand 20 is provided) will be described below.

As shown in FIG. 2, the side cover 40 extends in the front-rear direction. The side cover 40 is formed with a cutout portion 41 (second cutout portion) that opens downward in a side view. The cutout portion 41 of the side cover 40 is positioned to face the cutout portion 52a of the undercover 50 in the vertical direction. An opening O is formed in the exterior cover C by combining these cutouts 41 and 52a. As shown in FIG. 5, a portion of the side stand 20 and its surrounding structures are exposed to the outside of the exterior cover C through the opening O. As shown in FIG.

<Side stand>
As shown in FIG. 1 , the side stand 20 is attached to the left lower frame 14 of the vehicle body frame 11 . The side stand 20 is of a foldable type and configured to support the body of the motorcycle 1 in an upright state tilted to the left.
As shown in FIG. 5, the side stand 20 is rotatably supported by a stand bracket 30 fixed to the left lower frame 14. As shown in FIG. The side stand 20 rotates between a retracted position in which the tip side (ground side) is flipped up behind the rotating shaft 35 and a use position (upright position) in which the tip side extends below the rotating shaft 35. It is possible. In the figure, the side stand 20 in the use position is indicated by a dashed line.

The side stand 20 includes a stand bar 21, a pivot portion 22, and a ground portion 23 which are integrally formed. The stand bar 21 is, for example, a straight steel pipe or steel column. The pivot part 22 is provided on one end side (the base end side, the rotating shaft 35 side) of the stand bar 21 and is rotatably connected to the vehicle body side. The pivot portion 22 is attached to the vehicle body via a rotation shaft 35 and is rotatable around the rotation shaft 35 . A line C1 in the drawing indicates the central axis of the rotation shaft 35 . The grounding portion 23 is provided on the other end side (front end side, grounding side) of the stand bar 21 to support the vehicle body. A surface of the ground portion 23 facing the other end side is used as a ground surface 23a. When the side stand 20 is in the use position, the ground contact surface 23a faces downward and contacts the ground to support the vehicle body.

The rotating shaft 35 is inclined upward so as to be positioned upward toward the outer side in the vehicle width direction. As a result, the side stand 20 is projected outward in the vehicle width direction when the side stand 20 is at the standing position, and is prevented from projecting outward in the vehicle width direction when the side stand 20 is at the retracted position. Since the side stand 20 in the upright position protrudes outward in the vehicle width direction, the ground contact portion 23 is arranged outward in the vehicle width direction, and the body of the motorcycle 1 can be easily supported. By suppressing the outward protrusion of the side stand 20 in the retracted position in the vehicle width direction, the side stand 20 is less likely to touch the ground when the vehicle body is banked. The rotation shaft 35 is also inclined in the front-rear direction so that the outer side in the vehicle width direction is located on the front side.

The side stand 20 and its peripheral parts may unintentionally touch the ground when the vehicle body is greatly banked during cornering or when the vehicle rides over an uneven road surface. Therefore, in order to prevent the side stand 20 from affecting the bank angle and minimum ground clearance of the vehicle body, it is preferable that the side stand 20 is installed at a position as high as possible.

As shown in FIG. 5, the side stand 20 is provided with a locking hook 26 for locking one end of a stand spring (tension coil spring) 25 . The locking hook 26 is formed so as to protrude outward in the vehicle width direction from the middle portion in the longitudinal direction of the stand bar 21 and is welded and fixed to the stand bar 21 . A part of this locking hook 26 serves as a footrest 26a for the user to rotate the side stand 20 with his/her foot.

When the motorcycle 1 travels, the side stand 20 is positioned at the retracted position. Here, when the side stand 20 is in the retracted position, the ground contact surface 23a of the ground contact portion 23 faces substantially rearward. More specifically, the ground contact surface 23a extends obliquely upward and rearward. Therefore, when the muddy water splashes on the road surface while the motorcycle 1 is running, the muddy water hitting the ground contact surface 23a may rebound obliquely upward and rearward. The engine E and its related parts (for example, the air cleaner 18) are arranged behind and obliquely above the ground contact portion 23. As shown in FIG. In particular, as shown in FIG. 6, when the intake port 18a of the air cleaner 18 is arranged on an imaginary straight line L extending along the ground surface 23a, muddy water bounced off the ground surface 23a may reach the vicinity of the intake port 18a. have a nature.

Therefore, in this embodiment, a protective wall 54 is provided between the ground surface 23a and the intake port 18a. As shown in FIG. 4 , the protective wall 54 of this embodiment is formed to extend rearward from the undercover 50 . More specifically, the protective wall 54 is formed so as to protrude rearward from a portion of the left side wall portion 52 located rearward of the notch portion 52a. A through hole 54 a is formed in the rear end portion of the protective wall 54 . A screw B (see FIG. 7) inserted through the through-hole 54a is fastened to a screw hole (not shown) of the side cover 40, thereby increasing the strength of the protective wall 54. As shown in FIG. As shown in FIG. 3, the protection wall 54 is inclined upward as it goes rearward. The protection wall 54 is arranged along the lower surface of the side cover 40 .

An imaginary straight line L shown in FIG. 6 is a straight line extending along the ground plane 23a, and is also a straight line connecting the ground plane 23a and the intake port 18a. A protective wall 54 is positioned on the imaginary straight line L. As shown in FIG. Therefore, the protective wall 54 can effectively receive the muddy water that bounces off the ground contact surface 23a and tries to move straight toward the intake port 18a.

The muddy water bounced off the ground surface 23a does not always go straight to the intake port 18a, but may, for example, draw a parabola toward the intake port 18a. Therefore, the protective wall 54 does not necessarily have to be positioned on the imaginary straight line L. In this embodiment, the protective wall 54 is arranged above the ground surface 23a and below the intake port 18a. Furthermore, as shown in FIG. 7, the protective wall 54 is arranged so as to overlap the ground surface 23a when viewed from below. With this arrangement, the protective wall 54 can receive muddy water that bounces off the ground contact surface 23a during running and tries to move toward the intake port 18a located above the ground contact surface 23a.

In addition, the protective wall 54 of this embodiment is provided so as to suppress an increase in the air resistance of the motorcycle 1 . Specifically, when the motorcycle 1 travels, air flows into the exterior cover C from a gap in the exterior cover C (for example, between the front fender 16 and the body cowl 17 shown in FIG. 1). . Part of the air passes through the inside of the side cover 40 in the left-right direction and escapes to the rear of the motorcycle 1, as indicated by arrow F in FIG. Here, if the protective wall 54 itself or a member for providing the protective wall 54 is arranged so as to block the air flow indicated by the arrow F, the air resistance of the motorcycle 1 increases.

Therefore, in this embodiment, the protective wall 54 is arranged along the lower surface of the side cover 40 . Moreover, the protection wall 54 has a linear shape extending in the front-rear direction of the vehicle. The airflow indicated by arrow F in FIG. 7 flows through the space above the protection wall 54 and inside the side cover 40 . With such an arrangement, it is possible to suppress an increase in air resistance due to the protective wall 54 . Further, in this embodiment, the rear end portion of the side cover 40 is formed in a substantially linear shape along the front-rear direction. More specifically, the rear portion 42 of the side cover 40 is not provided with a portion that protrudes inward in the left-right direction. The rear portion 42 in this specification is a portion of the side cover 40 that is located behind the ground contact portion 23 when the side stand 20 is in the retracted position. Since the rear portion 42 does not have a portion that protrudes inward in the left-right direction, the air flow indicated by the arrow F becomes smooth, and the air resistance of the motorcycle 1 can be reduced.

As described above, the motorcycle 1 (saddle type vehicle) of this embodiment includes the body frame 11 (body), the exterior cover C that covers the body frame 11, and the body frame 11 that allows the stored position and the standing position to be adjusted. A side stand 20 is rotatably supported between the side stand 20 and has a ground surface 23a that contacts the ground when it is in an upright position, and an air cleaner 18 that purifies the air sucked from the intake port 18a. The exterior cover C includes an undercover 50 that covers the vehicle body frame 11 from below, and side covers 40 that stand upright from side edges of the undercover 50 . The under cover 50 and the side cover 40 form an opening O through which a part of the side stand 20 is passed, and the exterior cover C has an opening 0 above the ground contact surface 23a when the side stand 20 is in the retracted position and above the intake port 18a. A protective wall 54 positioned below is provided, and in a bottom view, the protective wall 54 overlaps the ground surface 23a when the side stand 20 is in the retracted position.

According to this configuration, even if muddy water strikes the ground contact surface 23 a during running and bounces upward, the muddy water can be received by the protective wall 54 . Therefore, it is possible to prevent the muddy water from reaching the intake port 18a located above the protective wall 54 .

Also, the protection wall 54 is formed in the undercover 50 . According to this configuration, by forming the protective wall 54 on the undercover 50 located at the lowest position in the exterior cover C, the protective wall 54 can be provided at a position close to the ground surface 23 a of the side stand 20 . Therefore, the muddy water bounced off the ground contact surface 23a can be more reliably received by the protective wall 54. - 特許庁

The protection wall (54) has a linear shape extending in the longitudinal direction of the vehicle. This configuration prevents the protective wall 54 from blocking the flow of air that flows into the outer cover C through the gaps in the outer cover C during running and is discharged to the rear of the motorcycle 1. can. Therefore, air resistance during running can be reduced.

In addition, the protective wall 54 is positioned on a straight line (imaginary straight line L) connecting the ground contact surface 23a and the intake port 18a when the side stand 20 is in the retracted position. With this configuration, the protective wall 54 can receive the muddy water that bounces off the ground surface 23a and travels linearly toward the intake port 18a. Therefore, it is possible to more effectively prevent muddy water from reaching the intake port 18a.

The technical scope of the present invention is not limited to the above embodiments, and various modifications can be made without departing from the scope of the present invention.

For example, the protection wall 54 may extend from a portion other than the left side wall portion 52 of the undercover 50 . Alternatively, the protection wall 54 may be formed on the exterior cover C other than the undercover 50 .
Further, the vehicle body to which the side stand 20 is attached is not limited to the vehicle body frame 11, and may be a structure attached to the vehicle body frame 11 or a power unit such as the engine E.

Straddle-type vehicles to which the present invention is applied include not only motorcycles but also vehicles in general that are equipped with a side stand.

In addition, it is possible to appropriately replace the components in the above-described embodiments with well-known components without departing from the scope of the present invention, and the above-described embodiments and modifications may be combined as appropriate.
