Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle fuel pipe piping structure, and more particularly to a vehicle fuel pipe piping structure which can prevent a fuel pipe from interfering with the layout of other parts.

[0002]

2. Description of the Related Art In a vehicle, there is provided a fuel supply device having a fuel pipe for guiding fuel from a fuel tank to an engine.

In the fuel piping structure of this fuel supply device, a fuel supply hose for guiding the fuel in the fuel tank to the engine in the engine room, a fuel supply pipe, and a fuel return hose for returning excess fuel to the fuel tank, a fuel return. A pipe and the like are provided. Fuel pipes such as fuel supply pipes and fuel return pipes extend along the vehicle body frame and are arranged side by side with pipes such as brake pipes and evaporative pipes in the engine room. It is fixed to the dash panel, which is the vehicle body side panel.

Examples of such a piping structure include, for example, Japanese Utility Model Laid-Open No. 60-75782 and Japanese Utility Model Laid-Open No. 61-170786.
No. 6,086,045. In Japanese Utility Model Laid-Open No. 60-75782, a bending piece is provided in a piping clamp member having at least one pipe holding portion, and a notch corresponding to the bending piece is formed in a mounting portion of the clamp member. Place the pipe holding part on one surface side of the mounting part, insert the bending piece into the notch and place it facing the other surface side of the mounting part, and under this condition, place the clamp member on the mounting part. It is fixed with screws. Further, the one disclosed in Japanese Utility Model Application Laid-Open No. 61-170786 discloses that a plurality of piping materials having a relatively small diameter are mutually provided on the resin layer of a plate-shaped metal clamp body having a resin layer adhered to the surface thereof. The pipes are arranged in parallel with a gap maintained, and each of the pipe members is held by a series of belt-shaped resin members and welded and fixed to the resin layer.

[0005]

However, in the conventional fuel piping structure, since the fuel pipe is simply arranged along with other pipes such as a brake pipe in the engine room, the fuel pipe is The occupied area in the engine room becomes large, which hinders the layout of other parts such as the engine mounting member.

Further, when the fuel pipe is arranged in the engine room at the rear of the vehicle body, the assembling property of the fuel pipe and the piping such as the fuel hose connected to the fuel pipe is deteriorated.

[0007]

Therefore, in order to eliminate the above-mentioned inconvenience, the present invention provides a vehicle fuel pipe piping structure in which a fuel pipe and a brake pipe are fixedly mounted on a vehicle body side panel by at least one clamp. ,
The fuel pipe and the brake pipe arranged on the front side of the vehicle body are fixed to the vehicle body side panel by the clamp, and the fuel pipe on the engine side of the clamp is located on the vehicle body front side of the brake pipe. Along with the brake pipe, the fuel pipe on the fuel tank side of the clamp is vertically overlapped with the brake pipe on the front side of the vehicle body.

[0008]

According to the structure of the present invention, since the fuel pipe on the engine side of the clamp is juxtaposed with the brake pipe on the vehicle front side, a space is formed in the engine room in the vertical direction. The pipes do not interfere with the layout of other parts, which increases the flexibility of the layout of other parts, and the fuel pipe is installed in the engine room on the front side of the vehicle. It is possible to improve the assemblability of the connected fuel hose.
