Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a motorcycle cowling lower mounting device.

[Conventional technology and its problems]

On high-speed motorcycles, the front part of the motorcycle body is covered with a streamlined cowling to reduce wind resistance and to reduce wind hitting the rider, reducing fatigue. Typically, cowlings are made of synthetic resin by molding, and the cowlings are molded into several pieces and then connected using screws or the like. A stay is provided protruding from the front end of the vehicle body, and brackets are fastened to the sides and bottom of the vehicle body, and a cowling is fastened to the stay and bracket with bolts. The cowling is a large piece that covers the front of the vehicle, and it is difficult to achieve dimensional accuracy in the mounting part, which can cause the cowling to flex, making it difficult to install.

[Purpose of the invention] In this invention, a bar is attached to the lower surface of the engine case, facing laterally, and cylindrical protrusions provided inside the lower parts of the left and right cowlings are fitted to both ends of this bar, so that the cowling can be correctly distributed in the left and right direction. The object of the present invention is to obtain a motorcycle cowling lower part mounting device which allows the lower part to be mounted.

[Structure of the idea]

The present invention will be explained below with reference to embodiments shown in the drawings.

The cowling is divided into an upper cowling 1 and left and right cowlings 2, molded with synthetic resin.
It is connected with screws. A transparent screen 3 is attached to the upper surface of the upper cowling 1. A boss 6 is provided protruding from the lower surface of an engine case 5 mounted on the front lower part of the vehicle body 4, and the central part of a bar 7 directed in the left-right direction is fastened to the boss 6 with a bolt 8. Then, elastic cups 9 are fitted into both ends of the bar 7. A cylindrical protrusion 10 is integrally molded on the inside of the lower part of the left and right cowlings 2, and this cylindrical protrusion 10 is fitted into the elastic cup 9, and the left and right cowlings 2 are assembled.
Install the lower part of the. The lower edges of the left and right cowlings 2 are bent to the lower side of the engine case 5, and the lower edges are overlapped at the center and tightened with screws 11. The upper cowling 1 is fastened to a stay 12 protruding from the front end of the vehicle body 4, and the upper portions of the left and right cowlings 2 are fastened to brackets 13 provided on the sides of the vehicle body 4.

[Operation of the invention] The bar 7 is fastened to a boss 6 provided on the lower surface of the engine case 5, so that the length of the bar 7 protruding from side to side can be made equal. Cylindrical protrusions 10 are provided at both ends of this bar 7 on the inside of the lower portions of the left and right cowlings 2.
Since the cowlings 2 are fitted together, the right and left cowlings 2 can be correctly distributed. A slight dimensional difference can be absorbed by the elastic cup 9, the mounting accuracy can be increased, and the left and right cowlings 2 can be mounted without being forcibly distorted.

[Effect of idea]

As explained above, this idea involves horizontally tightening a bar with elastic cups fitted at both ends to the boss provided on the bottom surface of the engine case, and integrally forming cylindrical protrusions inside the lower portions of the left and right cowlings. The cylindrical protrusion is fitted into the elastic cup, and the lower edges of the left and right cowlings are overlapped and tightened on the lower surface, so the left and right distribution positions of the lower parts of the left and right cowlings can be determined by the bar fastened to the engine case. It can be installed correctly, and slight dimensional differences can be absorbed by the elastic cup, allowing for highly accurate installation without causing undue distortion to the left and right cowlings. The cylindrical protrusion is located on the inside and is not exposed on the outside, giving it a good appearance.
In addition, the elastic cup can also prevent vibrations.
