Abstract

(57) [Summary] (Corrected) [Purpose] To extend the effective life of the silencer for leaf springs and prevent squeaking. [Structure] Regarding a silencer for a leaf spring, a wall thickness a on the tip end side of the leaf is formed in a wedge shape thicker than a wall thickness b on the leaf center side.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a silencer structure of leaf springs interposed between leaves of leaf springs of vehicles such as automobiles.

[0002]

[Prior Art]

 As is well known, a silencer made of synthetic resin or hard rubber is usually interposed between the leaves of the leaf spring in order to reduce wear of the leaves.

In the conventional silencer 10 shown in FIGS. 7 to 8, the leaf tip end side end portion 10a and the leaf center side end portion 10b have the same thickness b.

[0004]

[Problems to be solved by the device]

 Therefore, the wear of the leaf tip end 10a of the silencer 10 is larger than the wear of the leaf center end 10b. For this reason, the effect life of the silencer 10 is short, and the leaf tip comes into contact with the metal to cause squeak noise.

An object of the present invention is to provide a silencer structure of a leaf spring that extends the effective life and prevents generation of squeak noise.

[0006]

[Means for Solving the Problems]

 According to the present invention, in the silencer structure of the leaf spring interposed between the leaves of the leaf spring of the vehicle, the silencer is formed in a wedge shape in which the thickness of the leaf tip side is thicker than the thickness of the leaf center side. .

[0007]

[Action]

 In the leaf spring silencer structure configured as described above, by making the thickness of the leaf spring tip side where the silencer wears larger than the leaf center side, the life of securing the leaf tip gap is longer than that of the conventional silencer. By extending the leaf tip, it is possible to secure a leaf tip gap that does not cause any practical problems without curling the leaf tip unlike the prior art.

[0008]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 to 3, a leaf spring generally designated by reference numeral 6 is attached to a frame 1 via a front spring bracket 2, a rear spring bracket 3 and a shackle 4, and a central portion of the leaf spring 6 and the frame. A shock absorber 5 is interposed between the first and second shock absorbers. Further, silencers 7 and 8 are provided between the tip of the second leaf 6b and the first leaf 6a of the leaf spring 6 and between the tip of the third leaf 6c and the second leaf 6b, respectively. The leaf No. 6b and the No. 3 leaf 6c are set and inserted in silencer mounting holes 9a, 9b formed in the No. 3 leaf 6c.

The silencer 7 will be described as an example with reference to FIGS. 4 to 6. The silencer 7 has a wedge shape in which the wall thickness a of the leaf tip side end portion 7a is thicker than the wall thickness b of the leaf center side end portion 7b. The lower surface is provided with a protrusion 7c that fits into the silencer mounting hole 9a. The reference numeral 7d in the drawing denotes a tab of a protrusion provided on the silencer side so that the silencer does not fall out of the leaf hole.

Therefore, by forming the wall thickness a of the leaf tip side end portion 7a, where the silencer wears a lot, to be thicker than the wall thickness b of the leaf center side end portion 7b, the leaf tip clearance can be made smaller than in the conventional silencer. The life of the leaf can be extended and the leaf tip clearance can be secured without any problem in practice without curling the leaf tip unlike the prior art.

[0012]

[Effect of the device]

 Since the present invention is configured as described above, it is possible to extend the effective life and prevent the generation of squeaking noise.
