Description

The invention relates to a two-wheeled motorcycle with a spare side cover covering the side of the main frame of the two-wheeled motorcycle which can be freely assembled and disassembled.

It is well known to support auxiliary parts on a main frame part including a main frame part protruding rearwardly from a front tube of a motorcycle, and to cover the auxiliary parts of the frame part with a cover. As an example, see JP-A-3-167084.

This kind of car cover is generally composed of multiple separate parts. The side cover covering the side of the main frame is wider than the side of the main frame, and is generally installed directly on the main frame with small screws. of.

The rear of a general two-wheeled motorcycle is equipped with a tubular seat rail from the main frame to the rear. When auxiliary parts are arranged at the rear of the vehicle body, the structure is to weld or fix brackets on the seat rail. parts to support.

That is, in order to extend the seat rail as a reinforcing member around the rear fender, there is a side where the space is sacrificed by using the pipe of the seat rail.

Here, in order to constitute the rear part of the vehicle body, although there are examples where the seat rails are not extended, in the example described in the Japanese Unexamined Publication No. 62-97892, the seats are clamped from the reinforcing plates installed on the left and right sides of the frame. For the rear fender, the plate-shaped holding plate is extended to the rear, and the rear fender is supported on the rear seat together with the holding bar.

Unexamined Patent Application Publication No. 1-150186 shows an example in which an auxiliary part is mounted on a rear fender.

However, even if the vehicle is manufactured by attaching side covers, it is popular to remove the side covers, and the main frame has a large side, and in order to make it an attractive part, a design is sometimes used to expose it.

However, in the above-mentioned former example, the side cover exceeds the side width of the main frame, and generally covers auxiliary parts such as lubricating oil tanks and electrical components. When the side cover is removed, due to the exposure of these auxiliary parts, the two The motorcycle does not look good.

Even if the main frame is flexibly used as an appearance part, generally small screws are used to directly install the side cover and the like on the side of the main frame. Such installation traces, even if the side of the main frame is deliberately used, is difficult.

Therefore, in fact, it is difficult to change the structure made into an additional side cover into a person who simply removes the side cover. When two methods are expected, two forms must be considered separately, which is uneconomical as a result.

In the previous example of the rear structure of the car body, for the former example, since the auxiliary parts are not arranged at the rear of the car body, it is necessary to ensure more space for the auxiliary parts elsewhere. up the appearance. Especially because of the large number of parts such as holding hostages.

On the other hand, in the latter case, the auxiliary parts are arranged at the rear of the vehicle body, and the places where these are arranged are the side positions, and are placed on the frame above the rear fender, so there is no room for placing the auxiliary parts.

In order to solve these problems, an object of the present invention is to prevent the appearance of the vehicle body from being exposed even when the side cover is taken or disassembled at the front of the vehicle body.

Another object is to secure sufficient space for auxiliary parts and the like in the rear of the vehicle body, and to provide a rear structure of the vehicle body capable of forming a slender vehicle body appearance.

In order to solve the above-mentioned problems, the two-wheeled motorcycle of the present application is equipped with a vertically long main frame with a predetermined side width from the front pipe to the lower central part of the vehicle body in the up and down direction and the engine below the main frame. It is characterized in that: The separate part constitutes a car cover that covers the aforementioned main frame and the engine substantially continuously, while making one of the separate covers freely removable along the side of the aforementioned main frame.

In addition, the above-mentioned car cover is composed of a plurality of separate parts as follows: an upper cover extending forward and rearward along the upper surface of the main frame to cover the upper part of the main frame; The cover and the lower cover arranged under the side cover along the lower side of the main frame and whose upper end is connected to the lower end of the side cover, the side cover is arranged to extend forward and rearward along the side of the main frame with approximately the same width, and at the same time it is adjacent to the car cover Other components can be freely disassembled.

In this way, once the separated car cover along the side of the main frame is removed with approximately the same width, the outer side of the main frame is exposed, and no installation traces are left on this surface, and it is difficult to expose the appearance of auxiliary parts. , so the main frame can be made into a desired surface with a conceived appearance.

Furthermore, since the side cover can be separated from the upper cover and the lower cover respectively, even if the side cover is removed, the upper cover and the lower cover can still be installed on the car body, keeping the function of the original car cover. Auxiliary parts and the like having a poor appearance are covered without being exposed, and these auxiliary parts and the like can be protected.

Therefore, it is possible to change conveniently and quickly between the two methods of simply disassembling and assembling the side cover, not exposing the main frame with the side cover, and adopting the exposed side cover as an appearance part, and it is also economical.

Also, add the above-mentioned side cover, cover the side of the engine radiator with at least a part of the lower cover, and form the air outlet of the radiator at the side of the lower cover.

Furthermore, a rear fender formed by a plate-shaped frame may also be provided on a structural member of the rear frame behind the aforementioned main frame at the rear portion of the vehicle body, and auxiliary components may be arranged on the rear fender.

In this way, the rear fender is formed according to the plate-shaped frame instead of the tubular frame, and the space for auxiliary parts is ensured. The auxiliary parts are arranged on the rear fender. Get slim.

An upper frame connected front and rear is provided between the main frame and the rear frame behind it, a fuel tank can be arranged on the upper frame, and the upper end of the shock absorber for rear wheel suspension is arranged below it.

In this way, since the fuel tank is arranged on the upper frame, the wheel suspension damper and other auxiliary parts can be accommodated in the space below, and the width of the vehicle body is narrow, and the appearance of the entire vehicle body is slim.
