Description
【発明の詳細な説明】 （産業上の利用分野） 本発明は、車両のロードシミュレータ装置に関するもの
である。The present invention relates to a vehicle road simulator device.
（従来の技術） 一般に自動車等の車両は、その開発に際して、また製造
完了後の性能評価等に際して各種の性能試験が行われ
る。(Prior Art) Generally, a vehicle such as an automobile is subjected to various performance tests at the time of its development and at the time of performance evaluation after completion of manufacturing.
その中でも特に実路面の変位に対応して快適な乗心地を
維持できるか否かを測定評価する振動乗心地試験には、
各種の路面形態を形成したテストコースを実走して測定
評価する方法と人工的な加振手段を備え、該加振手段に
より車両に対し実路面の形態に応じた加振状態を形成し
て測定評価するロードシミュレーション法の２つの方法
がある。前者の場合には、設備自体がはるかに大がかり
なものになることに加え、実路面に対応した形態の路面
形成にも実際上限界があり、余り複雑な加振状態を形成
することは不可能である。また、横風の有無等部条件の
変化によって測定条件が変化しやすい。これに対して後
者の場合には、測定条件を常に一定に保つことができる
とともに相当に複雑な加振状態をも比較的自由に形成す

にはない利点がある。Among them, especially for the vibration ride comfort test that measures and evaluates whether a comfortable ride comfort can be maintained in response to the displacement of the actual road surface,
Equipped with a method for actually measuring and evaluating a test course on which various road surface shapes have been formed, and an artificial vibration means, and the vibration means forms a vibration state according to the shape of the actual road surface on the vehicle. There are two methods, a road simulation method for measuring and evaluating. In the former case, the equipment itself will be much larger, and there is also a practical limit to the formation of the road surface that corresponds to the actual road surface, and it is impossible to form a too complicated vibration state. Is. In addition, the measurement conditions are likely to change due to changes in conditions such as the presence or absence of cross wind. On the other hand, in the latter case, the measurement conditions can always be kept constant, a considerably complicated vibration state can be formed relatively freely, and the measurement is easy. There are advantages that the former does not have.
そして、このロードシミュレーション法には、従来は例

方向の振動は、本来当該タイヤを介して加振状態を形成
するのでなければ正確に実走状態をシミュレーションし
たことにはならない、と言った問題もある。(Problems to be Solved by the Invention) However, in the above-described configuration of the related art, only vibrations in the vertical direction of the axle are simply formed, and a complicated driving condition corresponding to a combination of vibrations in the vehicle front-rear direction is applied. There is a problem that the vibration state cannot be realized. In addition, the vehicle vertical vibration that is actually loaded via the tire, which is an elastic body, simulates the actual running state unless the vibration state is originally formed through the tire. There is also a problem saying that this is not the case.

の近似度はさらに高くなる。Moreover, the vehicle vertical vibration force is applied to the tire 5 itself via the base portion 10 supporting the tire 5 and transmitted to the vehicle body via the tire, while the axle 2 Since the vibration in the vehicle front-rear direction is applied to the vehicle through the holding portion 12 including the U-shaped rod 17 that holds the axle 2 only in the front-back direction, the tire 5 itself is eventually moved in the up-down direction. The movement is free without any restriction, and the case where the tire 5 rebounds due to the sudden vibration in the vehicle vertical direction can be freely reproduced. Therefore, the degree of approximation to the actual running state becomes higher.

Is not limited to the case where the U-shaped rod 17 is used. For example, it is constituted by an H-shaped member 17 'as shown in FIG. 2 as the second embodiment, and the center of the H-shaped member 17' is used. The side 17a 'is thinned to form an engaging space A for the axle 2 extending in the vertical direction on the inside, while the central side 1
The displacement of the axle 2 in the vehicle width direction may be prevented by 7a '.

近似させることができる。Therefore, according to the present invention, in addition to the vehicle vertical direction vibration means, the vehicle longitudinal direction vibration means is further provided, and therefore, the vehicle vertical direction and longitudinal direction vibration states are formed as well as both directions thereof. It is possible to easily form a considerably complicated vibration state in which the vibrations of 1 are combined and to approximate the actual running state.

Since the addition of the vibration of the tire is made through the sandwiching portion that sandwiches the axle only in the front-rear direction, the tire itself can move freely in the up-down direction, and the vibration of the vehicle in the up-down direction causes the tire to move. It is possible to freely reproduce the case where is rebound. Therefore, the degree of approximation to the actual running state becomes higher.
