本発明は自動車等の懸架機構部に設けられる車両用スタ
ビライザ装置に関する。DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention relates to a vehicle stabilizer device provided in a suspension mechanism of an automobile or the like.
周知のように自動車においては、ロール剛性を補助する
一手段として懸架機構部にスタビライザが使用される。As is well known, in automobiles, stabilizers are used in suspension mechanisms as a means of assisting roll rigidity.

る。この種のスタビライザは、良路におけるコーナリン
グ時などでは車体姿勢を効果的に安定させ得るが、悪路
走行時にはかえって車輪の接地性を損う原因ともなる。A conventional stabilizer includes a torsion part 1 along the left-right direction of the vehicle, as shown in FIG. 8 and FIG.
When the axle 3 swings up and down and the amount of swing of the axle 3 relative to the frame 4 differs from side to side, twisting occurs in the torsion part 1. The force that opposes this appears as a stabilizer effect, which attempts to keep the vehicle body horizontal. Although this type of stabilizer can effectively stabilize the vehicle body posture when cornering on a good road, it can actually impair the ground contact of the wheels when driving on a rough road.
このため、例えば悪路走行の頻度の高い車両にあっては
、必要に応じてスタビライザ効果をオン・オフできるよ
うにすることが望まれる。For this reason, for example, in vehicles that frequently drive on rough roads, it is desirable to be able to turn the stabilizer effect on and off as needed.

場合があるが、これはコストを全く無視したものであり
、簡便さあるいはコスト的な面で一般自動車には適応が
難しい。However, in the past, there was no vehicle in general use that could turn on and off the stabilizer effect with a simple structure. For example, a special device called an adjustable stabilizer is sometimes installed in competition cars, but this completely ignores cost and is difficult to apply to general cars due to simplicity and cost.
本発明は上記事情に基づきなされたものでその目的とす

用スタビライザ装置を提供することにある。The present invention has been made based on the above circumstances, and its purpose is to provide a stabilizer device for a vehicle that can turn the stabilizer effect on and off depending on driving conditions and has a relatively simple structure. It is in.

- In a vehicle stabilizer device comprising arm parts located at both ends of a John part, at least one of the arm parts has a first rotating member and a second rotating part connected to each other by a pivot shaft so as to rotate in a specific direction. A hinge-type joint capable of swinging is provided so as to be rotatable around the axis of the arm portion, and a joint driving means is provided to rotate the joint in the direction around the axis and stop at a specific rotational position. That's true.

となる。In the stabilizer device having the above configuration, while the vehicle is running, bending is applied to the left and right arm portions due to unevenness of the road surface, etc., like in a general stabilizer. However, if the joint is rotated so that the direction in which the first rotating member and the second rotating member of the joint swing coincide with the direction in which bending is applied to the arm portion, the bending force applied to the arm portion can be Since the first rotating member and the second rotating member freely swing around the pivot, the left and right arm portions are substantially not interlocked with each other, and therefore the stabilizer effect is no longer exhibited. In other words, it is in an off state. On the other hand, if the joint is rotated, for example, by about 90 degrees so that the direction in which the first rotating member and the second rotating member can swing does not match the direction in which bending is applied to the arm, the bending applied to the arm can be avoided. On the other hand, since the first rotating member and the second rotating member are in a mutually restrained state, the bending applied to one arm can be transmitted to the other arm via the 1-john, similar to a general stabilizer. This allows the stabilizer effect to be demonstrated. In other words, it is in an on state.

2a, the joint 18 is locked in the first rotational position described above. Also 90° from this position
Another toothless portion 42b is installed on the gear 34 so that the joint 18 can be locked in a second, out-of-phase rotational position. By exciting the electromagnetic coil 45, the lock par 40 can be moved in the direction of extraction from the toothless portion 42a or 4, 2b. That is, the locking member 40 is controlled in a sequence as illustrated in FIG. 6, and in short, the joint 18 is repeatedly rotated and locked by 90 degrees. Note that it is of course possible to use a locking mechanism other than the structure described above.

。On the other hand, when driving on a good road, the joint 18 is rotated 90 degrees to the second rotation position, so that the first rotation member 19
and the direction in which the second rotating member 21 can swing is determined by the arm portion 15
perpendicular to the direction of bending. By doing this, the first rotating member 19 and the second rotating member 21 are restrained from each other with respect to the bending direction of the arm portion.
Similar to a general stabilizer, the bending applied to one arm can be transmitted to the other arm via the torsion part 10, and the stabilizer effect is exhibited. In other words, it is in an on state. Therefore, the vehicle body posture can be effectively stabilized when cornering on a good road.
