Abstract

(57) [Abstract] [Purpose] The object is to provide a simple structure and versatility. [Structure] When the side member 10 and the cross member 11 are riveted by the flange portions 10A and 10B of the side member 10, a plate 15 having a rivet escape hole 17 is formed on the upper surface of the flange portion 10A of the side member 10. A vehicle frame characterized by being installed.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a frame for a vehicle in which a cross member is laterally fixed to left and right side members to form a ladder shape.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, as a vehicle frame of this type, as shown in FIG. 4, a conventional example of Japanese Utility Model Laid-Open No. 58-3375, that is, a side member 1 and a cross member 2, a rivet 3 is formed on a flange surface 1A of the side member 1. However, when mounting a bodywork on the upper surface of the flange surface 1A of the side member 1, it is necessary to provide a notch 4A for rivet relief in the vertical joist 4, which is a troublesome process. is there.

Therefore, in the device disclosed in Japanese Utility Model Laid-Open No. 58-3375, the upper flange surface 1A of the side member 1 is partially depressed as shown in FIG. 5, and the cross member is formed at the depressed portion 1B. It has been proposed to rivetly couple the two.

[0004]

[Problems to be solved by the device]

 By adopting the device disclosed in Japanese Utility Model Laid-Open No. 58-3375, it is not necessary to provide a cutout for rivet relief in the vertical joist 4, but the upper flange surface of the side member 1 is not provided. When a large press work such as partially crushing 1A is required, the structure of the side member 1 differs depending on the vehicle model, and the rivet connection part with the cross member 2 also differs. There is also a problem.

[0005]

[Means for solving problems]

 The present invention has been made to solve the above-mentioned conventional problems, and an object thereof is to provide a simple structure and versatility. A vehicle frame is characterized in that a plate having a rivet escape hole is mounted on the upper surface of the flange of the side member when the side member and the cross member are riveted together at the flange of the side member.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in FIGS. 1 is an enlarged partial view of a vehicle frame according to the present invention, FIG. 2 is a sectional view taken along the line II-II of FIG. 1, and FIG. 3 is a plan view of the vehicle frame.

In the figure, reference numeral 10 denotes a side member having a U-shaped cross-section. A cross member 11 having the same cross-section is horizontally placed at a desired interval between a pair of the side members 10 and 10 arranged in parallel. The member 10 and the cross member 11 are connected to each other by upper gussets 12A and 12B with upper flanges 10A and 11A and lower flanges 10B and 11B, respectively, and are connected to each other by rivets 13. The frame 14 is configured.

Reference numeral 15 denotes a plate, which is fixed to the upper surface of the upper flange 10 A of the side member 10 by welding 16. The plate 15 has the rivet 13 at the rivet joint portion between the side member 10 and the cross member 11. An escape hole 17 having a size for accommodating the head portion 13A is formed. In the figure, 18 is a vertical joist.

Since the head portion 13A of the rivet 13 is completely immersed in the escape hole 17 of the plate 15, when the vertical joist 18 is mounted on the upper surface of the upper flange 10A of the side member 10. The vertical joist 18 is good for sitting. Although the side member 10 and the cross member 11 are riveted to each other via the gussets 12A and 12B in the above embodiment, the gussets 12A and 12B may be omitted and the rivets may be directly connected to each other.

[0010]

As described above, in the vehicle frame according to the present invention, when the side member and the cross member are riveted with the flange portion of the side member through the gusset, the flange portion of the side member is Since a plate having a rivet escape hole is mounted on the upper surface, it is only necessary to add plates, and it is not necessary to perform any processing on joists or side members. Therefore, there are various effects such that the side member having the conventional structure can be used as it is while it can be provided at a low price, and it has versatility.
