Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a support structure for suspension members such as leaf springs.

[0002]

[Prior art]

 For example, as disclosed in Japanese Utility Model Application Laid-Open No. 60-170207, a support bracket for supporting a leaf spring has a support bracket provided with a pair of opposing support pieces on a side member arranged at a lower portion of a vehicle body. By fixing, by inserting the support shaft supporting the end portion in the length direction of the leaf spring into the insertion hole formed in the support piece, and screwing the nut on the insertion end portion of the support shaft, While supporting the leaf spring on the support shaft installed between the both support brackets, a reinforcing member is disposed inward of the support bracket in the vehicle width direction in order to increase the support rigidity of the support bracket. Then, a welding flange provided at the end of the reinforcing member is fixed to the inner wall of one of the support pieces by spot welding.

[0003]

[Problems to be solved by the device]

 By the way, in order to further increase the support rigidity of the support bracket by the reinforcing member, the area of the welding flange may be widened and fixed to the support piece. In such a method, the support piece of the welding flange is used. The number of spot welding spots for the spot welding increases, and the spot welding work becomes complicated accordingly.

The present invention was developed in view of the above circumstances, and it is an object of the present invention to effectively utilize a support shaft inserted through and supported by the support bracket and a nut screwed to the support shaft, It is an object of the present invention to provide a support structure for a suspension member that can reasonably enhance the support rigidity of the suspension member without increasing the spot welding points.

[0005]

According to the present invention, the side member 1 is provided with a support bracket 3 having a pair of first and second support pieces 3a and 3b facing each other. The support shaft 4 supporting the suspension member 5 is inserted into the insertion holes 31a and 31b formed in the support shaft 3 and the support shaft 4 is fixed by a nut 40 screwed to the support shaft 4, while the first In the vehicle in which the end portion of the reinforcing member 6 is fixed to the side surface of the support piece 3a, the extended wall portion 7 that overlaps around the insertion hole 31a in the first support piece 3a is provided at the end portion of the reinforcement member 6. The extension wall 7 is formed with a communication hole 70 communicating with the insertion hole 31a, and the nut 40 is screwed to the support shaft 4 inserted into the insertion hole 31a and the communication hole 70. The extension wall portion 7 is attached to the support piece 3a. It is characterized in that the tanning was.

[0006]

[Action]

 According to the present invention, the extension wall portion 7 is fixed to the support piece 3a through the support shaft 4 and the nut 40 around the insertion hole 31a of the support piece 3a. The load input from the suspension member 5 to the support shaft 4 without being connected to the 3a by spot welding can be directly supported not only by the support bracket 3 but also by the reinforcing member 6 through the extension wall portion 7. The support rigidity of the suspension member 5 can be increased.

【Example】

 In the figure, reference numeral 1 denotes a side member having a substantially U-shaped cross section disposed in the lower surface of a floor panel 2 and 3 denotes a support bracket fixed to the side member 1. The support bracket 3 is a pair of opposing members. The first and second support pieces 3a and 3b are provided, and the upper end portions of the first and second support pieces 3a and 3b are fixed to the left and right side wall portions 1a and 1b of the side member 1 by welding. . Insertion holes 31a and 31b are provided opposite to the support pieces 3a and 3b, and the support shaft 4 inserted and supported in the insertion holes 31a and 31b supports the lengthwise end portion of the leaf spring 5 that constitutes the suspension member. I have it.

The front ends of the support pieces 3a and 3b are connected by a connecting wall 3c.

Further, the support bracket 3 is provided inwardly of the support bracket 3 in the vehicle width direction with opposed wall portions 6a and 6b facing each other and a connecting wall portion 6c connecting the lower ends of the opposed wall portions 6a and 6b. A reinforcing member 6 having a substantially U-shaped cross section is provided, and first and second welding flanges 61 and 62 provided on the upper edges of the opposing wall portions 6a and 6b are fixed to the lower surface of the floor panel 2 by welding. In addition, the inner wall of the side member 1 is provided with the third flange 63 provided at the longitudinal ends of the reinforcing member 6, that is, at the longitudinal ends of the facing wall portions 6a and 6b and the connecting wall portion 6c. The portions 1a and the inner surfaces of the first support pieces 3a in the vehicle width direction are fixed by welding.

With the above configuration, in the embodiment shown in the drawings, an extension that overlaps the lower end portion of the third flange 63 of the reinforcing member 6 around the insertion hole 31a of the first support piece 3a. The wall portion 7 is extended and a communication hole 70 communicating with the insertion hole 31a is formed in the extension wall portion 7.

Then, the support shaft 4 supporting the leaf spring 5 is inserted from the insertion hole 31b of the second support piece 3b into the insertion hole 31a of the first support piece 3a and the communication hole 70 of the extension wall portion 7. Then, the supporting shaft 4 is assembled to the support bracket 3 by simultaneously tightening the nut 40 on the insertion end portion thereof, and at the same time, the extension wall portion 7 is inserted into the insertion hole 31a of the first support piece 3a. Tighten it around you.

Thus, since the extension wall portion 7 is fastened together with the support shaft 4 and the nut 40 to the support portion of the support shaft 4 in the support piece 3 a, the extension wall portion 7 is fixed. It is not necessary to connect the supporting piece 3a to the supporting piece 3a by spot welding, and the load input from the leaf spring 5 to the supporting shaft 4 is not limited to the supporting bracket 3 but via the extension wall portion 7 to the reinforcing member 6. However, the leaf spring 5 is directly supported, so that the supporting rigidity of the leaf spring 5 is increased.

In the above embodiments, the suspension member is applied to the support structure of the leaf spring, but the suspension member may be applied to a support structure of, for example, a lateral rod or a trailing arm.

[0014]

[Effect of device]

 As described above, according to the present invention, the support shaft 4 for supporting the suspension member 5 is inserted into the through holes 31a, 31b formed in the support pieces 3a, 3b of the support bracket 3 to support the support shaft 4. In a vehicle in which the end of the reinforcing member 6 is fixed to the side surface of the first supporting piece 3a while being fixed by the nut 40 screwed to the shaft 4, the first supporting piece 3a is attached to the end of the reinforcing member 6. The extension wall portion 7 that overlaps around the insertion hole 31a is provided, and a communication hole 70 that communicates with the insertion hole 31a is formed in the extension wall portion 7 and is inserted into the insertion hole 31a and the communication hole 70. By connecting the extension wall 7 to the support piece 3a by screwing the nut 40 onto the support shaft 4, the extension wall 7 is not joined to the support piece 3a by spot welding. The leaf sp The load input from the ring 5 to the support shaft 4 can be directly supported not only by the support bracket 3 but also by the reinforcing member 6 through the extension wall portion 7, and thus the addition of spot welding points is caused. Without this, the support rigidity of the suspension member 5 can be sufficiently enhanced.
