Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to the mounting structure of tension rods in the suspension of vehicles such as large buses. do.

0002

[Conventional technology]

In the air suspension of large vehicles such as buses, the frame and Secure the position of the lateral rod and axle to prevent lateral vibration of the vehicle body. A tension rod such as a radius rod (torque rod) is installed.

0003 For example, in the rear suspension shown in FIG. 4, the vehicle The middle part of the support beam 2 extending in the front-rear direction is attached, and these supports Two lower radius rods 3 are installed between the front end of the beam 2 and the frame (not shown). , 3 are stretched vertically, and the intermediate part (differential part) of the rear axle 1 and the Similarly, one upper radius rod 4 is vertically stretched between the arm and the arm. Also , one lateral rod 5 is installed between one end of the axle 1 and the frame. It will be strung up. In Figure 4, 6 is an air spring and 7 is a shock absorber. , 8 is a stabilizer.

0004 The lower radius rod 3 and the like are fitted at both ends thereof by press-fitting or the like. Mounting bracket on the frame or axle side via bush 9 as shown in Figures 5 and 6. It was connected to the kit 10 with a bolt 11.

[0005] That is, the bushing 9 has an inner collar 13 having bolt insertion holes 12 at both ends. Then, the metal fitting 14 and the outer collar are fitted in order to the outer periphery of the intermediate part of the inner collar 13. A dust cover 16 is interposed between the collar 15, the inner collar 13, and the metal fitting 14. between the resin bearing 17 mounted on the metal fitting 14 and the outer collar 15. The inner collar 13 has a yoke shape at both ends. The mounting bracket 10 is connected to both ends of the mounting bracket 10 with bolts 11.

[0006]

[Problem that the idea aims to solve]

However, in the conventional tension rod mounting structure as described above, two tension rods are attached. Use of bolts increases assembly man-hours and costs. There was a problem with that.

[0007] Therefore, the purpose of this invention is to improve assembly ease and reduce costs by reducing the number of parts. We have decided to provide a tension rod mounting structure that can achieve this.

[0008]

[Means to solve the problem]

In order to achieve the above object, the structure of the present invention is a suspension system for a vehicle. At least one end of a tension rod stretched between the arm and the axle is fitted into the end. A through-bolt that can pass through the inner collar of the bushing attached to the frame or axle. It is characterized by being coupled to a U-shaped mounting bracket attached to the handle.

[0009]

[Effect]

According to the above configuration, at least one end of the tension rod is assembled with one through bolt. This reduces the number of man-hours required.

0010

【Example】

Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings. Figure 1 is a plan view showing how the upper radius rod is installed as a tension rod, Figure 2 3 is a side view of the upper radius rod, and FIG. 3 is a half sectional view of the bushing. Furthermore, Figure 1 - In Fig. 3, the same members as in Figs. 4 to 6 are given the same reference numerals and duplicate explanations are omitted. Omitted.

[0011] As shown in FIGS. 1 and 2, one end of the upper radius rod 4 has a bushing shown in FIG. The bushing 9 is press-fitted, and the bushing 20 according to the present invention is press-fitted to the other end. So The one bushing 9 is mounted in a yoke shape similar to the conventional one using two bolts 11. The other bushing 20 is connected to the attached bracket 10, and the other bushing 20 is connected to the rear axle 1. One through bolt is attached to the U-shaped sheet metal mounting bracket 21 according to the present invention attached to the 22.

0012 The other bushing 20 has a shorter orifice diameter than the aforementioned one, as also shown in FIG. inner collar 23, metal fittings 24 and fittings fitted to the outer periphery of this inner collar 23 in sequence. A dust cover 26 is installed between the outer collar 25, the inner collar 23, and the metal fittings 24. The resin bearing 27 attached via the metal fitting 24 and the outer collar 2 5 and a rubber 28 installed between the inner collar 23 and the inner collar 23. The mounting bracket 21 is arranged to sandwich the collar 23 at both end faces thereof. However, they are connected by a through bolt 22 passing through the inner collar 23.

[0013] Because of this configuration, the other end of the upper radius rod 4 has one through-bore. It can be connected to the rear axle 1 side with the bolt 22, improving the ease of installation. In addition, Appara A bushing similar to the bushing 20 at the other end can also be used on one end of the dias rod. Needless to say, it can be connected to the frame side with a single through bolt in the same way as the other end. Nor. In addition, it is not limited to the upper radius rod 4, but also the lower radius rod 3 and the latex rod. It goes without saying that the present invention can also be applied to Ral Rod 5.

[0014]

[Effect of the idea]

As explained above, according to the present invention, the ends of the tension rods are connected with one through bolt. Since the number of parts can be reduced, ease of assembly and cost reduction can be achieved. I can figure it out.
