Abstract

PROBLEM TO BE SOLVED: To prevent damage of a radiator based on contact with an obstacle and a fall, etc., by mounting the radiator on a protector covering outward in the vehicle width direction of the radiator and supporting the protector on a vehicle body by a mounting member which is lower than the protector in rigidity. SOLUTION: A radiator 20 is mounted on a protector 21 covering the front side of the radiator 20 from outward of the vehicle width direction of the radiator 20. An upper bracket 40 and a lower bracket 50 mounting the protector 21 on a vehicle body are formed by a mounting member which is lower than the protector 21 in rigidity, that is, a plate which is thin in plate thickness, when the protector 21 is aluminum diecast, for instance. The protector 21 is supported on the vehicle body with each bolt 46, 53 via only upper bracket 40 and lower bracket 50. Therefore, when the radiator comes into contact with an obstacle or is fallen, the damage can be prevented because the upper and lower brackets 40, 50 are deformed and the radiator is displaced together with the protector 21.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a motorcycle having a radiator.

[0002]

2. Description of the Related Art Some motorcycles are equipped with a water-cooled engine, and are provided with a radiator for cooling the cooling water by a traveling wind. The radiator is long in the vehicle width direction so as to efficiently receive the traveling wind, but may be damaged due to contact with an obstacle or a fall.

[0003]

For this reason, there is a type in which the radiator is covered and protected by a protector attached to the frame by means different from the radiator, but the protector to be protected is deformed due to contact with an obstacle or a fall. However, the deformed protector may damage the radiator. Further, if the protector is made of high rigidity without deformation, the protector mounting portion on the frame side will be deformed, which makes the repair troublesome and expensive.

[0004] The present invention has been made in view of such circumstances, and has as its object to provide a motorcycle that prevents damage to a radiator due to contact with an obstacle or fall.

[0005]

According to a first aspect of the present invention, there is provided a motorcycle having a vehicle body provided with a radiator, wherein the radiator includes at least a vehicle width of the radiator. Attached to a protector that covers the outside in the direction, the protector is supported by the vehicle body only through an attachment member having a lower rigidity than the protector. The protector that covers and protects the radiator may come into contact with obstacles or fall over.If a more than predetermined impact is applied to the protector, the mounting member that is less rigid than the protector will deform and reduce the impact on the protector. Since it is displaced together with the protector, its damage can be prevented.

The invention according to claim 2 is characterized in that the mounting member having low rigidity is detachable from the protector and the vehicle body. When the mounting member having a lower rigidity than the protector is deformed, it can be removed from the protector and the vehicle body and only the mounting member can be replaced, and the handling is easy and inexpensive.

The vehicle body mounting portion 40c of the upper bracket 40 is
Collar 4 is attached to bracket 44 fixed to cross member 43.
It is tightened and fixed by a bolt 46 via the connector 5 and is detachable from the vehicle body 2. The cross member 43 connects the main frame 4 and the upper down tube 5.

The lower mounting portion 21b of the protector 21 includes:
A mounting hole 21b3 and a mounting boss 21b4 are formed. Lower bracket 5 attached to lower attachment portion 21b
0 is formed as shown in FIGS.
That is, the lower bracket 50 constituting the mounting member is formed by pressing a sheet metal, has a mounting nut portion 50a, a mounting boss engagement notch 50b, and further has a vehicle body mounting portion 50c.
have. The lower bracket 50 engages the mounting boss notch 50b with the mounting boss portion 21b4 of the protector 21, fits the mounting nut portion 50a into the mounting hole 21b3, and is fixed by a bolt 51 to be detachable.
The vehicle body mounting portion 50c of the lower bracket 50 is fastened and fixed to a bracket 52 fixed to the lower down tube 6 by bolts 53, and is detachable from the vehicle body 2.

The outer mounting portion 21c of the protector 21 includes
The mounting notch 21c1 is formed, and the mounting notch 21c is formed.
1, the inside of the radiator cover 18 is fixed. That is,
A nut 99 is attached to the inside of the radiator cover 18 with a screw 54. The nut 99 is deformed by tightening the screw 54, and the radiator cover 18 is fixed to the mounting notch 21c1. The radiator cover 18 is fastened and fixed to the side of the fuel tank 16 at two upper and lower portions, extends from the side of the fuel tank 16 to the front, covers the upper side of the radiator 20, and the component 42 is not visible from the side of the vehicle body. Like that.

A fuel tank 16 is disposed behind the radiator 20 at a predetermined distance as shown in FIG.
A supply pipe 60 from the engine 12 is connected to an upper position of the radiator 20, and a return pipe 61 to the engine 12 is connected to a lower position of the radiator 20 so that cooling water flows from above to below to cool the cooling water. I have.

A protector 21 covers the side of the radiator 20 from the front side, and a component 42 is disposed behind the radiator 20. The part 42 is located between the position above the radiator 20 and the fuel tank 16 and the radiator cover 18.
It is arranged in the dead space of the portion covered by. As shown in FIG. 3, a portion B in which the radiator cover 18 is notched and a portion A in which the passage of the traveling wind is relatively restricted as compared with the lower region C of the radiator cover 18 are formed.

The component 42 is disposed behind the portion A where the passage of the traveling wind is restricted by the radiator 20, the protector 21 and the radiator cover 18, so that the air that has cooled the radiator 20 is prevented from hitting the component 42, This prevents the component 42 from being affected by heat. Further, since the radiator cover 18 covers the side of the component 42, the appearance of the component 42 can be reduced even if the component 42 is arranged.

As described above, the radiator 20 is attached to the protector 21 which covers the front side of the radiator 20 from the outside in the vehicle width direction, and the upper bracket 40 and the lower bracket 50 for attaching the protector 21 to the vehicle body have lower rigidity than the protector 21. When the mounting member, for example, the protector 21 is an aluminum die-cast, it is formed of a thin sheet metal. The protector 21 is supported on the vehicle body 2 only through the upper bracket 40 and the lower bracket 50.

Therefore, if the protector 21 that covers and protects the radiator 20 comes into contact with an obstacle or falls down and a given impact is applied to the protector 21, the upper bracket 40 and the lower bracket 50 having lower rigidity than the protector 21 are deformed. Thus, the impact applied to the protector 21 is reduced, and the radiator is displaced together with the protector 21, so that the breakage can be prevented.

The upper bracket 40 and the lower bracket 50 constituting the low-rigid mounting member are provided with the protector 21.
When the upper bracket 40 and the lower bracket 50 are deformed, the upper bracket 40 and the lower bracket 50 can be easily removed from the protector 21 and the vehicle body 2, and only the upper bracket 40 and the lower bracket 50 can be replaced. It is.

[0023]

As described above, according to the first aspect of the present invention, the protector that covers and protects the radiator may come into contact with an obstacle or fall, and when the protector is subjected to a predetermined impact or more, the protector is more rigid than the protector. The impact of the lower mounting member on the protector due to deformation is reduced, and the radiator is displaced together with the protector.

According to the second aspect of the present invention, when the mounting member having a lower rigidity than the protector is deformed, the mounting member can be removed from the protector and the vehicle body and only the mounting member can be replaced, and the handling is easy and inexpensive.
