Description

[Detailed Description of the Invention] The present invention relates to a mounting structure for covers such as under cowls and radiator covers of motorcycles.

Motorcycles equipped with water-cooled engines are equipped with a radiator, and if the radiator is placed in front of the down tube due to space layout,
The radiuator cover is usually mounted and supported on the frame side by providing a stay on the down tube, or mounted and supported on the radiuator with a stay. on the other hand,
When a radiator is provided and an undercowl is provided below the radiator, the undercowl is mounted and supported via a stay provided on the down tube.

In such a conventional structure, the number of parts increases because the stays are provided on the frame side, and the structure of the frame becomes complicated because these parts are welded to the down tube, etc., and the manufacturing of the frame is also complicated and troublesome. It requires more man-hours, and since the radiator cover and under cowl are attached via separate stays, assembly errors are likely to occur.
There is also a problem in terms of appearance because there is a step between the radiator cover and the undercowl.

The present invention has been developed in view of the above, and its purpose is to attach and support the radiator cover via the radiator, and to attach and support the under cowl via the radiator, and to attach and support the frame support stays. The number of parts has been reduced by eliminating the radiator cover, the frame structure has been simplified, and the mounting accuracy of both parts has been improved by supporting the radiator cover and under cowl. It is an object of the present invention to provide a cover mounting structure for a motorcycle that achieves mounting support and improves appearance.

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

FIG. 1 is a schematic side view of a motorcycle 1, in which a front fork 4 supporting a front wheel 5 is supported in a steerable manner on a head tube 3 at the front end of a frame 2, a handle 7 is provided on a top bridge 6, and a handle 7 is provided in front of this. The provided headlight 8 and meter unit 9 are covered with a fairing 10.

A fuel tank 11 is installed at the front upper part of the frame 2.
Also, an engine 12 is mounted below this, a seat 13 is extended behind the fuel tank 11, and a frame 2 is mounted.
A rear fork 14 that supports a rear wheel 15 is pivoted and extends rearward from the lower rear end of the front part.

The engine 12 is of a water-cooled type and includes a radiator 16. The radiator 16 is provided in front of and parallel to a down tube 2a that extends downwardly and rearward from the lower part of the head tube 3 of the frame 2. A locking projection 17 projecting from the upper end is fitted and locked to a stay 18 projecting forward from the top of the down tube via a mount rubber 19. A stay 20 is provided rearwardly at the bottom of the radiuator 16, while a down tube 2
a A brachit 21 that protrudes laterally is provided at the middle lower part, and a mounting hole 20a provided in a part of the stay 20.
Insert the rubber bush 22 into the bracket 21.
Attach the rubber bush 2 to the nut 23 fixed inside the
2 and screw the bolt 24 through the radiator 1.
The lower part of 6 is mounted and supported on the down tube 2a for vibration isolation. 25 in the figure is a washer. This is shown in Figure 3.

For example, a bracket 26 is provided hanging downwardly at the middle part of the bottom surface 16a of the radiuator 16, and the upper piece 27a of the stay 27, which has an approximately inverted U-shaped side surface, is attached to the supporting piece 26a bent and protruding from the side of the bracket 26 with a screw 28. ,
The lower piece 2 is connected by a nut 29 and extends backward and downward from the lower end of the vertical piece 27b of the stay 27.
7c to under cowl 30, screw 31, nut 32
It concludes with. The under cowl 30 covers the lower part of the down tube 2a and the front part of the down tube blower 2b extending rearward from the lower end of the down tube.
A hole 30b is provided in the hole 30b, the stay 27 is passed through it, and the upper wall 3
Mounting piece 3 extending downward and rearward from the front end of 0a
0c and the lower piece 27c of the stay 27 are connected with a screw 31 and a nut 32. Undercowl 30 like this
is mounted and supported on the radiuator 16. A rear part 30d of the under cowl 30 faces the front side of the down tube 2b, and a nut 33 is welded to the side of the lower cowl 2b, and an inner piece 35a of a planar U-shaped stay 35 is fastened to this via a bolt 34. The outer piece 35b of this is tied to the rear part 30d via a screw 36, a nut 37 and a collar 38. Thus, Undercowl 30
The rear part will be attached and supported to the frame side. This is shown in Figure 4.

Cover 39 the front and side surfaces of the radiuator 16
The front piece 39a is covered with
A number of slits 39c are provided on the top and bottom of the cover 39, and the left and right upper pieces 39d bent and extended rearward from the upper end of the front piece 39a of the cover 39 are connected to the radiator upper surface 16.
Fit and lock the locking protrusions 40 protruding on the left and right sides of b through the mount rubber 41, and attach by bending the rear end of the lower piece 39e, which is bent backward from the lower end of the front piece 39a, downward. A piece 39f is formed, and this is attached to a stay 42 hanging from the left and right sides of the lower surface 16a of the radiuator 16.
are connected to each other via screws 43 and nuts 44.

The front and side surfaces of the radiuator cover 39 and the front end and side surfaces of the under cowl 30 are set to be flush with each other without any difference in level, and the front portion of the radiuator cover 39 is located below the front of the fuel tank 11. A front side cover 45 is provided so as to fit with the side surface.

As is clear from the above, according to the present invention, since the radiator cover and under cowl are attached and supported on the radiator as described above, there is no need to provide dedicated stays for each of the down tubes, and the number of parts can therefore be reduced. These stays are not attached to the frame, which simplifies the frame structure and makes manufacturing easier. On the other hand, since the stays are attached to the radiator, it can be easily welded during the manufacturing process. Furthermore, since the cover and under cowl are attached to the radiator, it is easy to align and assemble both, and this results in a front cover structure with excellent appearance and no stepped parts, as well as a mounting part for the under cowl. It has many advantages such as not being exposed to the outside.
