Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a fuel tank mounting structure for an automobile, and more particularly to a fuel tank mounting structure for an automobile that prevents the fuel tank from falling off in the event of a collision.

[Conventional technology]

Many of the conventional fuel tank mounting structures for automobiles have a suspension band around the bottom of the fuel tank and both ends of the suspension band are fixed to the vehicle body, or the flange of the fuel tank is fixed by mounting bolts. It is fixed to the vehicle body.

As a prior art of this type of fuel tank mounting structure for an automobile, there is one disclosed in Japanese Patent Publication No. 59-11435.

[Problems to be solved by the invention]

However, in the conventional vehicle fuel tank mounting structure as described above, when the suspension band is cut or the bolt is removed (most of the accidents are rear collisions),
There was a problem that the fuel tank fell off the car body and caused a secondary disaster.

So, in this device, in the unlikely event of an accident, the suspension band is cut, or the bolts that secure the fuel tank come off,
Even if it breaks, the purpose is to prevent it from falling off the vehicle body to the end.

[Means for solving problems]

In order to achieve the above-mentioned object, the present invention provides a suspension band and a fuel tank mounting structure for an automobile suspended and mounted on a vehicle body by a mounting bolt, wherein an upper portion of the fuel tank is in close contact with the body. A rear suspension cross member is arranged behind the lower portion, and inclined surfaces where the rear rises are formed in the upper and lower portions of the rear portion of the fuel tank, and the lower end of the fuel tank is formed at the upper end portion of the side surface of the rear suspension cross member. Is formed so that the rear portion of the fuel tank is sandwiched between the body and the rear suspension cross member.

[Action]

Even if the suspension band of the fuel tank is cut or the mounting bolt is removed due to an accident such as a rear surface collision, the fuel tank is not caught between the body and the rear suspension cross member and does not fall off.

〔Example〕

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. First, in the figure, reference numeral 6c indicates a body, and the body 6c and the upper portion (inclined surface) 5C of the fuel tank are in close contact with each other.
A propeller shaft 2 is arranged below the center of the fuel tank 5, and the propeller shaft 2 is input to a diff mechanism 3 via a universal joint 2A. The diff mechanism 3 is covered with the inverted U-shaped rear. A suspension cross member 4 is attached. An inclined surface 4A having an upper end inclined rearward is formed on the side surface of the rear suspension cross member 4, and the inclined surface 4A is associated with the fuel tank and extends along the length direction of the rear suspension cross member 4. Has been formed.

The fuel tank 5 is located between the body 6c and the rear suspension cross member 4, and the upper and lower portions of the fuel tank 5 at the rear have slopes 5C and 5A that rise rearward, and the lower slopes. 5A is defined so as to face the inclined surface 4A at the upper end of the side surface of the rear suspension cross member. The inclined surface 5A extends in the width direction of the fuel tank 5.

This fuel tank 5 is a cross member 4 for the rear suspension.
The two slanted surfaces 4A, 5A are placed on the top with a slight gap, and one end is fixed to the body 6 with the bolt 7A, and the other end 7B is fixed to the body 6B. It is turned around and suspended.

At this time, the fuel tank 5 is lifted by the lifting band 7.
The rear end upper surface 5x is housed inside the body 6 in the convex portion 6A.

In the state where the mounting is completed, the propeller shaft 2, the differential mechanism 3, and the rear suspension cross member 4 are located in the lower space and the rear space of the fuel tank 5, respectively.

Should the suspension band 7 break due to an accident, or
Even if the bolt 7A is broken, the fuel tank 5
The inclined surface 5A of the rear end is placed on the inclined surface 4A of the cross member 4 for the rear suspension, and the inclined surfaces 5A and 5c of the fuel tank 5 are inserted between the inclined surface 4A and the body 6c. It does not fall downward, in the case of a rear impact,
The differential mechanism 3 and the rear suspension cross member 4 protect the fuel tank 5.

Further, when removing the fuel tank 5, the bolt 7A is removed and the rear suspension cross member 4 is hung downward together with the rear suspension link, so that the gap between the inclined surfaces 4A and 5A becomes large and the fuel tank 5 is removed. It can be removed downward.

The bolt holes in the mounting portion of the rear suspension cross member 4 and the chassis are not elongated holes but are round holes so that the wheel alignment can be prevented from being misaligned and readjustment becomes unnecessary.

[Effect of device]

As is apparent from the above description, in the fuel tank mounting structure for an automobile of the present invention, the rear portion of the fuel tank is mounted on the rear suspension cross member and is sandwiched between the rear suspension cross member and the body. Since it is configured so that the fuel tank does not fall off even if an accident such as the suspension band breaks, the fuel tank is extremely effective for safety measures.
