Description
本発明は、自動車等車輌の防振用ブツシュで、捩り方向
の負荷に対して剛性を低くおさえる摺動型ブツシュ及び
その製造方法に関するものである。The present invention relates to a vibration-isolating bushing for vehicles such as automobiles, which has low rigidity against loads in the torsional direction, and a method for manufacturing the same.
従来より板バネの端部等に使用されるスタビライザー用

そこで、こうした問題を解決するために実願平１−４４

案されている。Rubber bushings for stabilizers, which are conventionally used at the ends of leaf springs, have a cylindrical elastic body (2
1) A sliding cloth (
23) is known. However, such bushings have a problem in that dirt, sand, water, etc. enter the bushings, causing them to wear quickly and making it impossible to maintain long-term performance. Therefore, in order to solve these problems,
In No. 830, as shown in Fig. 6, a cylindrical elastic body (21
) is provided with a sealing protrusion (24), and the sealing protrusion (24) is provided on the sealing protrusion (24).
A sliding type bushing in which the bushing (24) is covered with a sliding cloth (23) has been proposed.

た。However, although this structure certainly improves the durability of the sliding body, mud, sand, etc. can get caught in the seal protrusion or the mesh of the sliding fabric on the outside, causing damage to the other party. There was a problem in that the paint on the stabilizer bar was peeled off, rust occurred, and the stabilizer bar eventually broke. In addition, in the case of a conventional bushing in which a sliding cloth is attached to the inner peripheral surface of the cylindrical elastic body (21), since the sliding cloth is exposed at the end surface, it is difficult to hold both ends between the molding molds and hold them for molding. It was possible. However, when the structure of the present invention, which solves the above-mentioned problems described later, has seal protrusions at both ends, it is impossible to hold the sliding cloth and the position shifts due to the pressure when molding the elastic material. It was not possible to mold and fix it in position.

材を注入成形することとしたのである。As a result of various studies, we found that the structural problems of the sliding bushing were resolved by providing sealing protrusions (5) outward from the sliding cloth on the inner peripheral surface of the cylindrical elastic body and at both ends in the axial direction. That's what I did. In addition, a problem in manufacturing such a sliding bushing is that a protrusion (11) is provided in the molding die (10) so as to form a concave part inward in the axial direction from the seal protrusion (5), and the convex part (11) to hold the sliding cloth (4), and divide the mold so that one end is separated from the inner end of the axis of the convex part (11), and A tapered holding surface (12) is formed, and the tapered holding surface (12) is formed.
) to grip and hold the end of the sliding cloth (4), and then injection mold the elastic member.

In addition, in the method of manufacturing such a sliding bushing, the convex portion (11) of the mold for forming the seal protrusion (5) is
) and the tapered holding surface (12), the sliding cloth does not shift due to the injection pressure and can be molded and fixed in a predetermined position.

In the figure, reference numeral (1) is an insertion hole for a load member such as a stabilizer bar, in which a cylindrical elastic body (3) is provided via a sliding cloth (4). These cylindrical elastic bodies (3) have sliding cloths (4) on their inner peripheral surfaces and both ends in the axial direction.
) is provided with a sealing protrusion (5) (5) outwardly. In the example shown in Fig. 1, the seal protrusion (5) is provided in one thread near both ends of the inner circumference of the cylindrical elastic body (3), but as shown in Fig. 2, it is provided in two threads, or even more. Good too. Next, an example of a method for manufacturing a sliding bushing as described above will be described. In manufacturing the sliding bushing of the present invention, as shown in Fig. 3.4, in order to form four parts axially inward from the seal protrusion (5) of the cylindrical elastic body (3),
A convex portion (11) is provided on the molding die (10), and the convex portion (
11) to hold the sliding cloth (4). Furthermore, at one end of the molding die (upper part of the drawing), the molding die is divided in the direction perpendicular to the axis so as to separate the molding die from the inner end of the axis of the convex portion (11), and the dividing surface (J3) is tapered on the outer peripheral side. Holding surface (12)
is formed, and the sliding cloth (4) is formed on its tapered holding surface (12).
) After gripping and holding the peripheral edge of the end, an elastic member is injected from the injection port (14) and molded. As a result, the sliding cloth (4) is stably held at a predetermined position on the inner peripheral surface of the cylindrical elastic body (3) without being displaced by the injection pressure.
