Description

straddle vehicle

The present invention relates to a straddle type vehicle.

In a straddle-type vehicle, the handle and the front housing are integrally rotated. For example, in the straddle vehicle disclosed in Patent Document 1, the front housing is supported by the front fork. The front housing and the front fork are rotated together by the rider turning the handlebars to the left and right. [Prior Art Literature] [Patent Document]

[Patent Document 1] Japanese Patent Laid-Open No. 2007-126126

[Problem to be solved by the invention]

In the above-mentioned straddle-type vehicle, the footboard is disposed behind and below the front housing. When the front housing and the front fork rotate together, in order to prevent the front housing and the pedals from interfering with each other, a gap is provided between the front housing and the pedals. However, the gap causes muddy water splashed during driving to easily adhere to the rider's feet.

Also, because the front housing rotates, the front housing is likely to bump into objects around the vehicle. Therefore, even if the front case is damaged, it is not easy to maintain the front case. Furthermore, if the front case is enlarged in order to prevent splashing of muddy water, the front case will be damaged more easily.

Moreover, if the front housing becomes heavy due to the enlargement of the front housing, the steering operability decreases. An object of the present invention is to provide a straddle type vehicle that can suppress interference caused by the rotation of the front casing, suppress deterioration of steering operability, prevent muddy water from splashing on the rider's feet, and facilitate maintenance of the damaged front casing. [Technical means to solve the problem]

A straddle vehicle according to an aspect of the present invention includes a head pipe, a seat, a pedal, a steering device, a front wheel, and a front housing. The seat is arranged behind the head pipe. The pedals are arranged in front of and below the seat. The steering device is rotatably supported by the head pipe. The front wheels are rotatably supported by the steering device. The front shell covers the head pipe. The front housing is attached to the steering gear. The front housing swivels together with the steering.

The steering device includes a steering shaft, a bottom bracket, and a front suspension. The steering shaft is rotatably supported by the head pipe. The bottom bracket is connected to the steering shaft. The front suspension consists of an inner tube and an outer tube. The inner tube is connected to the bottom bracket. The outer tube supports the front wheel so that it can rotate.

The front case includes a center case portion, side case portions, and side guards. The center shell overlaps the head pipe when viewed from the front of the vehicle. The side shell part is arranged on the side of the central shell part. The side guards are separate entities from the side shell portions. The side guards are attached to the side housing parts.

The side guards are detachably attached to the side housing parts. The side guard is arranged with a gap between the side shell part and the side shell part. When viewed from the side of the vehicle, the side guards are arranged in front of the pedals. The side guards extend further below the bottom bracket.

In the straddle type vehicle of this aspect, the side guards which are separate from the side shell parts are attached to the side shell parts. Therefore, by downsizing the side housing portion, interference due to the swiveling of the front housing can be suppressed. Moreover, even if the gap between the side shell part and the footboard becomes large by the miniaturization of the side shell part, splashing of muddy water can be suppressed by the side guard greatly extending downward.

Furthermore, since the side guards are detachable, even if the side guards are damaged, it is easy to replace the side guards. Therefore, it is easy to maintain the shell before damage. Also, the side guard is disposed with a gap provided between the side guard and the side shell portion. Thereby, an increase in the weight of the front housing can be suppressed, and a reduction in steering operability can be suppressed.

The upper end of the side protector can also be located higher than the seat portion. In this case, the higher positions up to the side shell parts are protected by the side guards. The lower end of the side guard may be located further below the side shell portion. In this case, the lower positions up to the side shell parts are protected by the side guards.

When viewed from the side of the vehicle, the side protector can also extend from above the head tube to below the upper end of the outer tube along the axis of the front suspension. In this case, a large area of the side shell portion can be protected by the large side guard.

The side protector may also overlap at least a portion of the front suspension when viewed from the side of the vehicle. In this case, the front suspension can be protected by side guards. The side guards may also contain notches. In this case, the weight of the side guard can be reduced.

The side guard may include a first fixing portion and a second fixing portion. The first fixing part may be located above the notch. The first fixing portion may also be fixed to the side housing portion. The second fixing portion may be located below the notch. The second fixing part may also be fixed to the side case part. In this case, the reduction in the strength of the side guard due to the notch can be suppressed.

The side guards may also be formed from a higher strength material than the front shell. In this case, the strength of the side guard increases. The side guards may also be formed from transparent or translucent materials. In this case, the damage to the side guard is less conspicuous.

A straddle-type vehicle may furthermore be equipped with a flasher. The flasher can also be arranged above the side guard when the vehicle is viewed from the side. In this case, even if the side guards are enlarged, the visibility of the flasher can be ensured.

When viewed from the side of the vehicle, the flasher can also be arranged along the upper edge of the side shell. The front case may further include a cover. The cover part can also be installed on the upper edge of the side shell part. The cover may also cover the flasher from above. In this case, the installation of the flasher becomes easy.
