Abstract

PURPOSE:To prevent the occurrence of stress concentration due to the sudden change of a section modulus by connecting reinforcing members to the inner side of a pair of body side frames having a U-shaped cross section so that part of the cross section opening part of the side frames can be remained to connect brackets supporting an engine to these reinforcing members. CONSTITUTION:Side frames 2 have a U-shaped cross section, and reinforcing members 4 are fitted respectively to the inner sides of portions to which engine brackets 6 and 8 are connected. These portions have a half-opening cross section, and a section modulus is higher than that of a portion having a U-shaped cross section and is lower than in a case where a reinforcing part has a box state. Consequently a section modulus is not suddenly changed between a reinforced portion and an unreinforced portion to cause no stress concentration in a boundary line. Presser members 18 are connected to the tilted surfaces of the reinforcing members 4, and wiring and piping, etc., 22 arranged in the cross section opening part of the side frame 2 are pushed in the inside to be fixed. This work is to only fixing by the presser member 18, improving the efficiency of arranging work.

2. Description of the Related Art The body frame of a light truck is composed of a pair of side frames extending in the front-rear direction of the vehicle, and a plurality of cross members connected between the side frames. In the case of a small truck, the side frame is generally U-shaped in cross section.

However, since the portion of the side frame to which the bracket for supporting the engine is connected is reinforced in the shape of a box, the section modulus is larger than that of the portion of the side frame having a U-shaped cross section. It is quite high. Generally, where the section modulus changes rapidly,
Since stress concentration occurs, it is desirable to reinforce the side frame so that the section modulus does not change as rapidly as possible.

Wiring, piping and the like are arranged inside the side frame, but since the bracket mounting bolts and the like project inside the side frame reinforced in a box shape, There was a problem that the outer skin of the wiring and piping was damaged when the wiring and piping were passed through. Also, such work is very inefficient.

The side frame 2 has a U-shaped cross section, and reinforcing members 4 are attached to the insides of the side frame 2 at the portions where the brackets 6 and 8 are connected. The portion of the side frame 2 reinforced by the reinforcing member 4 has a half-open cross section, has a higher section modulus than a section having a U-shaped section, and has a lower section coefficient than when the reinforcing section is box-shaped. Therefore, the section modulus does not change abruptly between the portion reinforced by the reinforcing member 4 and the portion not reinforced, and stress concentration does not occur at the boundary between the reinforced portion of the side frame 2 and the other portion. .
