Abstract

(57) [Abstract] [Purpose] To improve the assembling accuracy of the upper rod hanger and the lower rod hanger that swingably support one end of the upper rod and the lower rod that suspend the rear wheel. [Structure] An upper rod hanger 16 and a lower rod hanger 17 that swingably support one end of an upper rod 4 and a lower rod 5 that suspend the rear wheel 2 are assembled to a rear suspension bracket 15, and the rear suspension bracket 15 is attached to the left and right. This is because the side frame 6 is separately mounted.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention aims to improve dimensional accuracy,
In addition, the present invention relates to a vehicle body structure that can reduce costs.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 8, there is a rear suspension of a four-wheeled vehicle that employs a 5-link rear suspension 1. This rear suspension 1
9, an axle beam 3 provided with wheels 2 on both sides thereof is swingably supported by a side frame 6 via an upper rod 4 and a lower rod 5, and both sides of the axle beam 3 are coil springs 7 respectively. And, it is supported by the shock absorber 8. A lateral rod 9 forming a 5-link is provided between the axle beam 3 and one axle.

The upper rod 4 and the lower rod 5 of the rear suspension 1 are shown in FIG.
0 and attached as shown in FIG. An extension 10 and a lower rod hanger 11 are welded to the left and right side frames 6, respectively, and a cross member 12 is mounted between the extensions 10. A pair of upper rod hangers 13 are welded to the cross member 12. The upper rod 4 and the lower rod 5 are swingably attached to the upper rod hanger 13 and the lower rod hanger 11 by means of bolts 14 and nads 14a. As shown in FIG. 12, the lower rod hanger 11 is composed of left and right two parts 11a and 11b.

[0004]

According to the above-mentioned conventional technique, the upper rod hanger 13 is provided with the cross member 12.
Since the cross member 12 is welded to the side frame 6, and the cross member 12 is mounted between the extensions 10 welded to the side frame 6, there is a problem that the mounting work is difficult and it is difficult to obtain dimensional accuracy with the lower rod hanger 11.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems of the prior art and to provide a vehicle body structure which is easy to mount, easy to obtain dimensional accuracy and easy to layout.

[0006]

In order to solve the above problems, the present invention assembles an upper rod hanger for suspending a rear wheel and an upper rod hanger for swingably supporting one end of a lower rod and a lower rod hanger into a rear suspension bracket. The rear suspension brackets are attached to the left and right side frames separately.

[0007]

[Operation] Assemble the upper rod hanger and the lower rod hanger to the rear suspension bracket. Then, attach the rear suspension brackets to the left and right side frames separately. Since the rear suspension bracket is simply attached to the frame, dimensional accuracy is easy to obtain.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings. 1 to 4 show an embodiment of the present invention in which the same parts as those in FIG. 10 are designated by the same reference numerals and the description thereof is omitted, and FIG. 1 shows that the rear suspension bracket 15 is attached to the side frame 6 by welding. FIG.

As shown in FIGS. 2 to 4, the rear suspension bracket 15 is a box-shaped bracket having an opening on one side and projecting mounting sides 15a and 15b for the frame 6 on the four sides of the opening. An upper rod hanger 16 and a lower rod hanger 17 are welded to the bracket 15.

The upper rod hanger 16 and the lower rod hanger 17 are each formed of a U-shaped plate, and the lower rod hanger 17 is reinforced by assembling a U-shaped reinforcing plate 18.

The upper rod hanger 16 and the lower rod hanger 17 have mounting holes 16a, 17a for axially supporting the upper rod or the lower rod on the plate surface.
Are drilled respectively.

According to the above construction, the upper rod hanger 16 and the lower rod hanger 17 are welded to the rear suspension bracket 15 in advance. A reinforcing plate 18 is welded to the lower rod hanger 16. And
The rear suspension brackets 15 are welded to the left and right frames 6, respectively. Rear suspension bracket 1
Since the upper rod hanger 16 and the lower rod hanger 17 are welded to the frame 5 in advance, the dimensional accuracy when the frame 5 is welded can be easily obtained.

Next, FIGS. 5 to 7 show another embodiment of the present invention, in which the same parts as those in FIG. 1 are designated by the same reference numerals and the description thereof is omitted. In this case, the engine mount bracket 19 and the tightening hook 20 are attached to the rear suspension bracket 15. Since the engine mount bracket 19 and the tightening hook 20 are required to withstand a large load, sufficient strength can be maintained by mounting the engine mount bracket 19 and the tightening hook 20 on the rigid rear suspension bracket 15.

[0014]

As described above, according to the vehicle body structure of the present invention, the upper rod hanger and the lower rod hanger that swingably support one end of the upper rod and the lower rod for suspending the rear wheel are mounted on the rear suspension bracket. Since the assembling and the rear suspension brackets are separately attached to the left and right side frames, the dimensional accuracy can be easily obtained in the assembling work, and the workability can be improved. Moreover, since the upper rod hanger and the lower rod hanger are attached to the rear suspension bracket, the dimensional accuracy between the upper rod hanger and the lower rod hanger is improved. Furthermore, since components that require mounting strength, such as the engine mount bracket and the tightening hooks, can be attached to the rear suspension bracket at the same time, it is possible to improve work efficiency and reduce costs.
