Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fuel tank supporting structure for supporting a cylindrical gas fuel tank on a vehicle.

[0002]

2. Description of the Related Art A fuel tank of a vehicle using natural gas or liquefied petroleum gas as a fuel has a cylindrical shape, and a supporting structure for mounting the fuel tank on the vehicle includes a horizontal rail frame and a vertical rail as shown in FIG. A bracket 10 comprising a frame portion is fixed to the frame of a vehicle by fixing the vertical frame portion to a vehicle frame, a non-slip rubber plate 11 is attached to the horizontal rail frame portion, and a fuel tank is mounted on the rubber plate 11 to form a vertical rail frame. As shown in FIG. 5, a structure in which the body of the fuel tank is fastened and fixed by a band (not shown) which is detachably laid over the top of the frame and the upper end of the horizontal rail frame, and as shown in FIG. The vertical surface of the arm 12 is fixed to the frame 2 of the vehicle, the fuel tank 1 is mounted on the curved surface, and the band is detachably wrapped over the vertical surface and the tip of the curved surface. A structure is used in which the body of the fuel tank is tightened and fixed.

[0003]

Since the bracket 10 is large, expensive and heavy, it is not easy to assemble it on a production line. The fuel tank 1 mounted on a rubber plate 11 is shown in FIG. As described above, since the rubber plate 11 is received in line contact, the anti-slipping action is not sufficient and stable support cannot be obtained, and the bracket 10 hinders the attachment / detachment of the fuel tank 1 and the vehicle is lifted by a lift or the like. Cannot be slid laterally to the side of the fuel tank 1 and must be detached from above, but this may require removal of an upper object such as a deck. Have disadvantages.

The arm 12 has a simple structure, a light weight, a low cost, and an advantage that it can be easily assembled on a production line. Cannot be slid in the lateral direction because of the interference of the front end of the fuel tank 1, which has a problem in the workability of attaching and detaching the fuel tank 1 like the bracket 10.

An object of the present invention is to provide a cylindrical fuel tank support structure which has improved workability in assembling, fuel tank support, and demounting work in a production line.

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention provides a fuel system in which a cylindrical fuel tank is fastened and supported to a vehicle frame by a band with a longitudinal direction of the fuel tank directed in a longitudinal direction of the vehicle. A support structure for a tank, wherein at least two L-shaped arms each including a vertical surface and a horizontal surface are attached at predetermined intervals in the front-rear direction of the vehicle with the front end of the horizontal surface facing the side of the vehicle. A surface is fixed to the frame, and one of two fuel tank receiving members forming an arc surface along a curved surface of the fuel tank on a lateral surface of the arm is detachably attached to a distal end side of the lateral surface. The other one of the fuel tank receiving members is fixed to the rear side of the lateral surface, and a band for tightening the body of the fuel tank placed on these two fuel tank receiving members is attached to the upper end of the vertical surface of the arm and to the side. Detachable between the tip of the surface It is characterized in that the.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a cylindrical fuel tank for storing natural gas or liquefied petroleum gas.

According to the present invention, at least two L-shaped arms 3 each having a vertical surface 3a and a horizontal surface 3b are oriented at predetermined intervals in the front-rear direction of the vehicle such that the ends of the horizontal surfaces 3b are directed to the side of the vehicle. The vertical surface 3a is fixed to the frame 2 of the vehicle.

On the lateral surface 3b of the arm 3, one fuel tank receiving member 4a of two fuel tank receiving members 4a, 4b forming arcuate surfaces 5a, 5b along the curved surface of the fuel tank 1 is provided. The other side of the fuel tank receiving member 4b is detachably attached to a tip end of the lateral surface 3b by a bolt 7.
Is fixed to the back side of the lateral surface 3b. A rubber plate 6 is mounted on the arcuate surfaces 5a, 5b of the fuel tank receiving members 4a, 4b along the arcuate surfaces 5a, 5b, and on a lateral surface 3b between the two fuel tank receiving members 4a, 4b. The rubber plate 6 is also attached.

Further, these two fuel tank receiving members 4
The arm 8 has a structure in which a band 8 for tightening the body of the fuel tank 1 placed on the a and 4b is detachably mounted between the upper end of the vertical surface 3a of the arm 3 and the tip of the lateral surface 3b.

Since the present invention has the structure as described above, the fuel tank 1 is provided on the lateral surface 3b of the arm 3.
The fuel tank 1 is supported on the vehicle via the arm 3 by being mounted on the arcuate surfaces 5a, 5b of the two fuel tank receiving members 4a, 4b and tightening and fixing the body of the fuel tank 1 with the band 8.

The fuel tank 1 supported by the vehicle via the arm 3 is supported by the rubber plates 6 on the arcuate surfaces 5a and 5b of the two fuel tank receiving members 4a and 4b. The rubber plate 6 also supports the lateral surface 3b between the receiving members 4a and 4b with wires. Therefore, the fuel tank 1
Is supported by the rubber plate 6 at three places of two surfaces and one line, so that the anti-slip action is sufficient and stable support is obtained.

The attachment and detachment of the fuel tank 1 can be performed from the lateral side of the vehicle. In particular, when the fuel tank 1 is taken out from the arm 3, the fuel tank receiving member 4a removably attached to the distal end side of the lateral surface 3b is removed, and the fuel tank receiving member 4a is removed from the lateral surface 3b to thereby lift or the like. Can be slid laterally to the side of the vehicle.

Therefore, as shown in FIG.
Even if there is an upper object 9 such as a deck above the fuel tank 1, if there is a small gap G, the fuel tank 1 does not need to be removed.
Can be easily detached.

The arm 3 uses a member used to support a rectangular liquid fuel tank, and is equipped with two fuel tank receiving members 4a and 4b. Since the fuel tank has a cylindrical fuel tank support structure for a vehicle using fuel, common parts can be obtained.

The number of the arms 3 is not limited to two, but two or more arms 3 are used according to the length of the fuel tank 1.

[0017]

As described above, according to the present invention, in the support of a fuel tank of a vehicle using natural gas or liquefied petroleum gas as a fuel, a sufficient anti-slip action and stable support can be obtained. Can be carried out from the lateral side of the vehicle, so that the detachability can be improved. In addition, since the structure is simple and lightweight, it is easy to assemble it on the production line, and the members used to support the liquid fuel tank can be used. it can.
