る。 In general, the front suspension of an automobile has a spindle 1 connected to a strut 2, as shown in Figure 1.
A transverse link 3 is provided to support the vehicle body (not shown), and one end of a tension rod 4 is attached to the transverse link 3 with a bolt 5, and is attached to a side member and a cross member (not shown) of the vehicle body. The other end of the tension rod 4 is attached to a bracket 6 attached to the bracket 6.
A pair of anti-vibration rubber bushings (only one of them is shown as 7 in Figure 1) is placed at the attachment point of the tension rod and bracket 6 to prevent shocks and vibrations without reducing the maneuverability or stability of the vehicle while it is running. It is designed to buffer the air and improve the ride comfort of the car.

て衝撃や振動を緩衝するよう構成されている。 FIG. 2 shows the conventional structure of the connection between the tension rod 4 and the bracket 6, which includes a pair of anti-vibration rubber bushings 7, which have hollowed out portions 8, 8' on the outer circumferential side surface.
7' are placed on both sides of the bracket 6, the collar 10 is inserted into the end of the tension rod 4 which is inserted into the mounting hole 9 of the bracket 6, and the anti-vibration rubber bushings 7,
Bush seats 11, 11' and 1 from the front and rear of 7'.
2, 12' with a nut 13,
This initial tightening force gives axial pre-compression determined by the length of the collar 10 to the vibration isolating rubber bushing to eliminate any looseness in the installation, thereby causing the tension rod 4 to receive an axial external force P1 or P. 2 compresses the vibration-proof rubber bushing 7 or 7' of the elastic body and tightens the tension rod 4.
is constructed so as to buffer shock and vibration by acting relative to the bracket 6.

る。 As a vibration-proof rubber bushing inserted in the connection between the tension rod 4 and the bracket 6 having the above-mentioned structure, a disc-shaped seat is provided on one side of the hollowed out part 8 on the outer circumferential side, as shown in the shape in the free state in Fig. 3. 14, and a canvas laminate (rubber sheet and cloth layered) 15 is embedded integrally inside this seat 14 by vulcanization, and has a soft characteristic against the initial load and sufficiently absorbs vibration. A conventional vibration damping structure has a seat 16 that is inclined on the other side of the hollowed out part 8 to absorb vibration, and a seat surface 17 that is inclined inward from the outer periphery (ascending slope), and has a through hole 18 in the center. When a rubber bushing is used, after the inclined seat 16 comes into contact with the cup-shaped bushing receiver 12 during installation of the anti-vibration rubber bushing, the seat 16 is deformed by being pre-compressed in the axial direction, as shown in FIG. tends to bulge outward over the wall surface 19 of the cup-shaped bushing receiver 12, and as a result, it is not possible to obtain the desired spring characteristics during use, and at the same time when an external force in the axial direction is applied during use, the bushing jumps out from the bushing receiver. There are problems such as changes in spring characteristics and deterioration of the bushing.

解消しようとするものである。 In view of the above-mentioned problems, an object of the present invention is to provide a concave portion in the inclined seat surface of the vibration-isolating rubber bushing, thereby absorbing the bulge during pre-compression during installation of the vibration-isolating rubber bushing and deformation during use. This is an attempt to solve the above-mentioned problems by configuring it so that the
以下、本発明を図面につき説明する。 The invention will now be explained with reference to the drawings.

してはみ出るのを防止する。 5 and 6 show an example of a vibration-proof rubber bushing according to the present invention.
A plurality of recesses 20 are provided at intervals in the circumferential direction on the inclined seating surface 17 extending inward from the outer circumference of the seat 6, and these recesses 20 are used to prevent preliminary compression during installation and bulge during deformation during use. It is absorbed and prevents it from riding on or climbing over the wall surface 19 of the cup-shaped receiving seat 12.
凹部２０の半径方向位置は取付に際しての予備

外側位置、すなわち、くり抜き部８の底８ａが位

つてゴム体の移動が拘束され、変形量を吸収する
効果をも発揮し得なくなるからである。 The radial position of the recess 20 is located outside the portion related to the tightening characteristics for providing preliminary compression during installation, that is, outside the radius D where the bottom 8a of the hollowed out portion 8 is located. The reason for this is that when the recess is provided inside the radius D mentioned above, such as in the peripheral area of the through hole 18, the axial stress applied for pre-compression in the axial direction does not act effectively, and the axial This is because not only the directional stress becomes unstable and the durability is impaired, but also the movement of the rubber body is restricted by the axial stress, and the effect of absorbing the amount of deformation cannot be exhibited.
図示の例では、矩形の凹所２０を設けている
が、円形その他の形状でも良く、また、必ずしも
同一円周上に設ける必要もない。 In the illustrated example, a rectangular recess 20 is provided, but the recess 20 may have a circular or other shape, and does not necessarily need to be provided on the same circumference.

ともない。 According to the present invention, by providing a recess in the inclined seat surface of the inclined seat, it is possible to effectively absorb the protrusion due to deformation during compression, which not only does not adversely affect the spring characteristics, but also prevents It has been confirmed that the spring constant of the vibrating rubber bushing does not increase even when subjected to 10 to 100 cycles of vibration, and a soft spring can be obtained. Furthermore, the durability of the rubber bushing can be improved, and since the concave portion is provided in the middle part of the seat surface rather than on the outer periphery, the strength of the bushing will not be reduced.
