Strap mounting structure of fuel tank for truck

The present invention relates to a strap mounting structure of a fuel tank for a truck, and in particular, the strap is in close contact with the upper surface and the side of the fuel tank so that the tightening force of the strap can be transmitted as it is to the fuel tank to prevent the flow of the fuel tank, This prevents the damage of the coupling portion of the strap, and relates to the strap mounting structure of the fuel tank for trucks that can be expected to improve the workability.

In general, fuel tanks installed in large trucks are mounted with straps on one side of the main body consisting of side frames and cross members.

1 to 3 show a strap mounting structure of a conventional fuel tank for trucks,

A support bracket (3) is formed horizontally at the lower end of one side of the main body (2) of the large truck, and the fuel tank (1) is placed on the upper side of the support bracket (3), and at the end of the support bracket (3) Coupling rods 5 for joining with the bolts 4 and 4 are formed, and bolt holes for inserting the bolts 6 are formed in the center of the coupling rods 5.

In the state where the fuel tank 1 is mounted on the support bracket 3, a strap 4 having a predetermined length for fixing the fuel tank 1 to the support bracket 3 and the main body 2 is provided with the fuel tank ( It is formed to surround one lower end from the upper side of 1), the end of the strap 4 is formed with a coupling portion 7 for coupling as a bolt (6).

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, FIGS. 4 to 7.

Reference numeral 10 denotes a fuel tank seated and fixed to a support bracket on one side of the main body of a heavy truck, and the edge 11 of the fuel tank 10 is rounded as shown in FIG. The bending force of the to be evenly transmitted to the flat portion of the fuel tank (10).

That is, the rounding radius of the corner 11 of the fuel tank 10 applied to the present invention is larger than the rounding radius of the conventional fuel tank.

In the present invention, the first strap 20 and the second strap 30 are provided as a means for bending the fuel tank 10.

The first strap 20 is configured to surround the side surface of the fuel tank 10 from a support bracket supporting the lower side of the fuel tank 10, and the second strap 30 covers the upper surface of the fuel tank 10. It is configured to wrap, the end of the first and second straps (20, 30) is coupled to the coupling means is bolted by the coupling bolt 40 in a state in which they are opposed to each other.

As shown in FIGS. 4 and 5, the coupling means may be formed by bending the ends of the first strap 20 and the second strap 30 in a circular manner so that the coupling rods 22 and 23 may be inserted, respectively. First and second coupling portions 21 and 31 are formed, and first and second coupling rods 22 and 32 are inserted into the coupling portions 21 and 31, respectively.
