が図られている。As shown in FIG. 10, one end of the lateral rod 2 is pivotally connected to the vehicle body side 4, and the other end is pivotally connected to the axle side 6, so as to support lateral loads generated when the automobile turns. Rubber pushers 8 and 10 are provided at both ends where the pivot connection is made, so that vibrations on the axle side are absorbed by the lateral rod 2.
This prevents it from being transmitted to the vehicle body side 4 through the. An axial view of this rubber pusher 8.10 is shown in FIG. 11, and a longitudinal sectional view is shown in FIG. 12. Further, the cross section of the lateral rod is U-shaped as shown in FIG. 13, and weight reduction is achieved.

体側４に伝わってしまうことがある。Problems to be Solved by the Invention However, even with the prior art described above, vibrations on the axle side 6 may be transmitted to the vehicle body side 4 through the lateral rod 2, and vibration-proofing measures are not sufficient. In particular, in cars with a 5-link suspension or 3-link suspension in the rear suspension and equipped with a rear differential 12, the gear sound of the rear differential is relatively loud, and the link mechanism of the rear suspension, especially the lateral rod 2. When the vibrations are transmitted to the vehicle body side 4, resonance may occur, the vibrations may be amplified, and large vibrations may be transmitted to the vehicle body side 4.

4 has an enlarged U-shaped cross section, and the other divided end 16 has a closed U-shaped cross section to have a circular cross section, and is provided with a collar 18. Inside the enlarged one divided end 14,
The other divided end 16 is inserted, and a rubber material 24, which is an elastic body, is filled between the inner wall 20 of the one divided end 14 and the outer wall 22 of the other divided end 16. Note that the end of one of the enlarged divided ends 4 is approximately closed by a flange 26, and the rubber material 24 is confined therein. Further, the collar 18 of the other divided end 16 is located inside the rubber material 24.

共振を生じることが抑止され、増幅した振動が伝えられ
ることを防止できる。The operation of this embodiment will be explained below. The vibrations transmitted through the lateral rod 2 must necessarily pass through the rubber material 24 at this divided portion, and the vibrations are absorbed at this time. In other words, this means changing the resonant frequency (natural frequency) of the entire lateral rod 2. Therefore, vibrations on the axle side 6 generated by the rear differential I2 (see FIG. 10) are suppressed from causing resonance in the lateral rod 2 as in the conventional case, and transmission of amplified vibrations can be prevented.

That is, the lateral rod 2 can have a large rigidity against a lateral load that is a large input in the longitudinal force direction, and can ensure maneuverability. Further, the collar 18 not only ensures the above-mentioned maneuverability, but also ensures the connection of both divided ends even if the rubber material 24 or the like is peeled or cracked, thereby ensuring safety.

In the above figures, the same parts as in the figures showing the first embodiment are given the same numbers. The difference from the first embodiment is that the flanges 18 provided on the other divided end 16 are provided at two locations in the longitudinal direction. In this embodiment as well, the function of the rubber material 24 greatly changes the resonant frequency of the entire lateral rod 2 to suppress resonance, and at the same time, the function of the collar 18 makes it possible to ensure maneuverability. In particular, by providing the flanges 18 at two locations, the maneuverability can be further improved, and at the same time, sufficient rigidity can be ensured against twisting and bending of the lateral rod 2.

The dotted line in the figure shows the case where the cap l8 is not provided. On the other hand, it can be seen that in the present embodiment in which the collar 18 is provided, the displacement can be made small against a large force, and the steering stability can be further improved.

It is formed. This recess 3
A pin hole 34 is formed in the bottom surface of 2, and corresponds to the pin hole 30 of the one split end 14, through which the pin 28 passes. Further, the inside of the recess 32 is filled with a rubber material 24, and this rubber material 24 is fixed to the wall surface of the recess 32, the inner wall of the one split end 14, the outer surface of the bottle 28, etc., so that the lateral rod 2 The divided parts of are connected. As shown in FIG. 9, the pin hole 30 is a long hole, so that when a lateral load is applied to the lateral rod 2, the pin 28

の実施例においては２対以上設けることも可能である。The operation of this embodiment will be explained below. Since the divided portions of the lateral rod 2 are connected via the rubber material 24, which is an elastic body, vibrations are attenuated by the action of the rubber material 24 when passing through the divided portions, and the vibrations of the lateral rod 2 are attenuated as before. It is possible to prevent resonance from occurring and being amplified. In other words, this means changing the resonance frequency of the entire lateral rod to suppress resonance. Further, the lateral load input when the lateral rod 2 performs its original function is also sufficiently supported through the rubber material 24. In particular, in this embodiment, compared to the above two embodiments, the rubber material 24 is confined inside the recess 32, and therefore can sufficiently support the lateral load. In addition, the cross section of the lateral rod at the divided portion is circular, and the recess 3
2 can also be easily crushed and processed using a cylindrical processing tool, and processing is also easy. Moreover, both divided ends 14.
Even if the rubber material 24 peels or cracks, the pin 28 penetrating through the rubber material 24 acts as a stopper to ensure safety. In this embodiment, two pairs of recesses 24 are provided in the longitudinal direction of the lateral rod 2, but in other embodiments, two or more pairs may be provided.
