Description

本発明は、自動車用のホィールの荷重付加による変位を計測するためのホィール変位計測装置に関するものである。   The present invention relates to a wheel displacement measuring device for measuring displacement due to load addition of a wheel for an automobile.

従来、自動車用のホィールの荷重付加による変位を計測するためのホィール変位計測装置は、図３に示される如く、ベースとなる本体フレーム１から、先端部にホィール２の変位基準点Ｏが位置するよう該ホィール２を取り付けるための取付シャフト３を略水平方向へ突設し、該取付シャフト３に取り付けられたホィール２に対して荷重を付与するための荷重付与装置４を前記本体フレーム１上に設置し、該本体フレーム１から支持アーム５，６を張り出させると共に、該支持アーム５，６に対し、前記荷重付与装置４によって荷重が付与されたホィール２の変位基準点Ｏに対する各部の変位を計測するためのセンサ７，８を配設してなる構成を有している。   2. Description of the Related Art Conventionally, a wheel displacement measuring device for measuring displacement due to load addition of a wheel for an automobile has a displacement reference point O of a wheel 2 positioned at the tip from a main body frame 1 as shown in FIG. A mounting shaft 3 for mounting the wheel 2 is projected in a substantially horizontal direction, and a load applying device 4 for applying a load to the wheel 2 mounted on the mounting shaft 3 is provided on the main body frame 1. The supporting arms 5 and 6 are extended from the main body frame 1, and the displacement of each part with respect to the displacement reference point O of the wheel 2 to which the load is applied by the load applying device 4 is applied to the supporting arms 5 and 6. It has the structure which arrange | positions the sensors 7 and 8 for measuring this.

前記荷重付与装置４は、ホィール２に嵌着されたタイヤ９に対し、その半径方向並びに軸線方向へ所望の荷重を作用させることにより、ホィール２に対して荷重を付与することができるようになっている。   The load applying device 4 can apply a load to the wheel 2 by applying a desired load to the tire 9 fitted to the wheel 2 in the radial direction and the axial direction. ing.

又、前記センサ７，８は、ホィール２の外表面並びに内周面に対向するよう支持アーム５，６に取り付けられ、例えば、光学式や渦電流式等の変位検出器が用いられており、ホィール２の外表面並びに内周面に対して非接触で変位基準点Ｏに対する変位を計測できるようになっている。   The sensors 7 and 8 are attached to the support arms 5 and 6 so as to face the outer surface and the inner peripheral surface of the wheel 2, for example, optical or eddy current type displacement detectors are used. The displacement with respect to the displacement reference point O can be measured without contact with the outer surface and the inner peripheral surface of the wheel 2.

前述の如きホィール変位計測装置においては、ホィール２を取付シャフト３の先端部に対し、図示していないボルト・ナットを用いて取り付け、先ず、ホィール２に対し荷重付与装置４によって荷重を付与しない無負荷の状態で、センサ７，８によりホィール２の外表面並びに内周面の所定箇所における変位基準点Ｏを原点とする座標を予め計測しておき、続いて、前記荷重付与装置４によってホィール２に嵌着されたタイヤ９に対し、その半径方向並びに軸線方向へ所望の荷重を作用させることにより、ホィール２に対して荷重を付与した状態で、前記センサ７，８によりホィール２の外表面並びに内周面の所定箇所における変位基準点Ｏを原点とする座標を計測し、該荷重付与時における座標と前記無負荷時における座標との差に基づいて、ホィール２の変位基準点Ｏに対する各部の変位を求めるようになっている。   In the wheel displacement measuring device as described above, the wheel 2 is attached to the tip of the mounting shaft 3 using bolts and nuts (not shown). First, no load is applied to the wheel 2 by the load applying device 4. In the state of load, the sensors 7 and 8 measure in advance coordinates with reference to the displacement reference point O at predetermined locations on the outer surface and the inner peripheral surface of the wheel 2, and then the load applying device 4 controls the wheel 2. By applying a desired load to the tire 9 fitted to the tire 9 in the radial direction and the axial direction, the outer surface of the wheel 2 and the wheel 2 are applied by the sensors 7 and 8 with the load applied to the wheel 2. Measure the coordinates with the origin of the displacement reference point O at a predetermined location on the inner peripheral surface, and based on the difference between the coordinates when the load is applied and the coordinates when there is no load , And obtains the displacement of each part with respect to the displacement reference point O of the wheel 2.

尚、図３に示されるような構造のホィール変位計測装置は、特許文献、非特許文献には見当たらないが、ホィールアライメント等、ホィールの車両への取付位置や取付角度を計測するものとしては、例えば特許文献１がある。
特開平６−３４４９４２号公報 In addition, although the wheel displacement measuring device of the structure as shown in FIG. 3 is not found in patent documents and non-patent documents, as a device for measuring the mounting position and mounting angle of the wheel on the vehicle, such as wheel alignment, For example, there is Patent Document 1.
Japanese Patent Laid-Open No. 6-344942

しかしながら、図３に示されるような従来のホィール変位計測装置の場合、センサ７，８は本体フレーム１から張り出させた支持アーム５，６に対して配設してあるため、ホィール２に対する荷重付与に伴って取付シャフト３が変形してホィール２の変位基準点Ｏが移動すると、該ホィール２の変位基準点Ｏに対するセンサ７，８の相対位置が変化してしまい、取付シャフト３の変形をホィール２自体の変形と切り離して無視することが困難となり、この結果、前記センサ７，８によって計測されるホィール２の各部の変位は、取付シャフト３の変形分を含んだものとなってしまい、計測精度が低下するという欠点を有していた。   However, in the case of the conventional wheel displacement measuring device as shown in FIG. 3, the sensors 7 and 8 are arranged with respect to the support arms 5 and 6 projecting from the main body frame 1, and therefore the load on the wheel 2. When the attachment shaft 3 is deformed with the application and the displacement reference point O of the wheel 2 moves, the relative positions of the sensors 7 and 8 with respect to the displacement reference point O of the wheel 2 change, and the attachment shaft 3 is deformed. It becomes difficult to disregard it separately from the deformation of the wheel 2 itself. As a result, the displacement of each part of the wheel 2 measured by the sensors 7 and 8 includes the deformation of the mounting shaft 3. There was a drawback that the measurement accuracy was lowered.

因みに、例えば、一般の乗用車の場合、ホィール２に対する荷重付与に伴って取付シャフト３に作用する垂直（半径方向）荷重と該取付シャフト３先端の軸たわみ量の関係は、図４に表わされるようになり、又、ホィール２に対する荷重付与に伴って取付シャフト３に作用する垂直（半径方向）荷重一定（図４のＡ点に相当）時に、水平（軸線方向）荷重を変化させたときの取付シャフト３先端の軸たわみ量の変化は、図５に示されるようになり、こうした軸たわみが取付シャフト３に発生することが、計測精度低下の要因となるわけである。   Incidentally, for example, in the case of a general passenger car, the relationship between the vertical (radial direction) load acting on the mounting shaft 3 as a load is applied to the wheel 2 and the amount of axial deflection at the tip of the mounting shaft 3 is shown in FIG. In addition, when the vertical (radial direction) load acting on the mounting shaft 3 with a load applied to the wheel 2 is constant (corresponding to point A in FIG. 4), the horizontal (axial direction) load is changed. The change in the amount of axial deflection at the tip of the shaft 3 is as shown in FIG. 5, and the occurrence of such axial deflection in the mounting shaft 3 causes a decrease in measurement accuracy.

本発明は、斯かる実情に鑑み、ホィールに対する荷重付与に伴う取付シャフトの変形の影響を受けなくすることができ、計測精度の向上を図り得るホィール変位計測装置を提供しようとするものである。   In view of such circumstances, the present invention is intended to provide a wheel displacement measuring device that can be prevented from being affected by deformation of the mounting shaft accompanying load application to the wheel and can improve measurement accuracy.

該取付シャフトに取り付けられたホィールに対して荷重を付与し得るよう前記本体フレーム上に設置された荷重付与装置と、

A load applying device installed on the main body frame so as to apply a load to a wheel attached to the attachment shaft;
A support arm attached to the tip of the mounting shaft so as to extend with the displacement reference point of the wheel as a support point;
A wheel displacement measuring device comprising: a sensor disposed on the support arm so as to measure a displacement of each part relative to a displacement reference point of the wheel to which a load is applied by the load applying device. Is.

上記手段によれば、以下のような作用が得られる。   According to the above means, the following operation can be obtained.

ホィールはその変位基準点が取付シャフトの先端部に位置するよう取り付けてあり、且つセンサは取付シャフトの先端部から延出させた支持アームに対して配設してあるため、ホィールに対する荷重付与に伴って取付シャフトがたとえ変形し、軸たわみが発生してホィールの変位基準点が移動したとしても、該ホィールの変位基準点に対するセンサの相対位置は変化せず、取付シャフトの変形をホィール自体の変形と切り離して無視することが可能となり、この結果、前記センサによって計測されるホィールの各部の変位は、あくまでもその変位基準点に対するものとなり、計測精度が高められることとなる。   The wheel is mounted so that its displacement reference point is located at the tip of the mounting shaft, and the sensor is mounted on the support arm that extends from the tip of the mounting shaft. As a result, even if the mounting shaft is deformed and axial deflection occurs and the wheel displacement reference point moves, the relative position of the sensor with respect to the wheel displacement reference point does not change, and the deformation of the mounting shaft does not change. It becomes possible to ignore the deformation separately from the deformation. As a result, the displacement of each part of the wheel measured by the sensor is only relative to the displacement reference point, and the measurement accuracy is improved.

以上、説明したように本発明のホィール変位計測装置によれば、ホィールに対する荷重付与に伴う取付シャフトの変形の影響を受けなくすることができ、計測精度の向上を図り得るという優れた効果を奏し得る。   As described above, according to the wheel displacement measuring device of the present invention, it is possible to eliminate the influence of the deformation of the mounting shaft accompanying the load application to the wheel, and it is possible to improve the measurement accuracy. obtain.

以下、本発明の実施の形態を図示例と共に説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１及び図２は本発明を実施する形態の一例であって、図中、図３と同一の符号を付した部分は同一物を表わしており、基本的な構成は図３に示す従来のものと同様であるが、本図示例の特徴とするところは、図１及び図２に示す如く、取付シャフト３の先端部に剛性の高い支持アーム５，６を、ホィール２の変位基準点Ｏを支持点として延出されるよう取り付け、該支持アーム５，６に対してセンサ７，８を配設した点にある。   1 and 2 show an example of an embodiment of the present invention. In the figure, the same reference numerals as those in FIG. 3 denote the same components, and the basic configuration is the conventional configuration shown in FIG. As shown in FIGS. 1 and 2, the features of the illustrated example are the same as those described above, except that the rigid support arms 5 and 6 are attached to the distal end portion of the mounting shaft 3 and the displacement reference point O of the wheel 2. Is attached to be extended as a support point, and sensors 7 and 8 are disposed on the support arms 5 and 6.

本図示例の場合、前記支持アーム５は、剛性の高い棒状体であって、ホィール２の軸心部に穿設されている中心孔１０を貫通させてホィール２の外表面側（図１及び図２中、左方）へ延ばし、該支持アーム５の先端部から垂下させた鉛直ステージ１１に、ホィール２の軸線方向ヘ延びる水平ステージ１２を上下方向へ位置調整可能に配設し、該水平ステージ１２に、前記センサ７をホィール２の軸線方向ヘ位置調整可能且つ円筒面からなる角度調整座１３を有する角度調整アタッチメント１４を介して角度調整可能に取り付けるようにしてあり、又、前記支持アーム６は、剛性の高い半割の筒状体であって、取付シャフト３の外周に沿ってその基端側（図１及び図２中、右方）へ延ばし、該支持アーム６の端部から垂下させた鉛直ステージ１５に、ホィール２の軸線方向ヘ延びる水平ステージ１６を上下方向へ位置調整可能に配設し、該水平ステージ１６に、前記センサ８をホィール２の軸線方向ヘ位置調整可能且つ円筒面からなる角度調整座１７を有する角度調整アタッチメント１８を介して角度調整可能に取り付けてある。   In the case of this illustrated example, the support arm 5 is a highly rigid rod-like body, and penetrates the center hole 10 drilled in the axial center portion of the wheel 2 so that the outer surface side of the wheel 2 (FIG. 1 and FIG. A horizontal stage 12 extending in the axial direction of the wheel 2 is disposed on the vertical stage 11 extending leftward in FIG. 2 and suspended from the tip of the support arm 5 so that the position of the horizontal stage 12 can be adjusted in the vertical direction. The sensor 7 is attached to the stage 12 via an angle adjustment attachment 14 having an angle adjustment seat 13 formed of a cylindrical surface so that the position of the sensor 7 can be adjusted in the axial direction of the wheel 2 and the support arm. 6 is a highly rigid half-divided cylindrical body that extends along the outer periphery of the mounting shaft 3 toward the base end side (to the right in FIGS. 1 and 2), from the end of the support arm 6. Vertical stage 1 drooped Further, a horizontal stage 16 extending in the axial direction of the wheel 2 is disposed so as to be adjustable in the vertical direction, and the angle of the sensor 8 can be adjusted in the axial direction of the wheel 2 on the horizontal stage 16 and the angle is made of a cylindrical surface. An angle adjustment attachment 18 having a seat 17 is attached so that the angle can be adjusted.

尚、前記センサ７が装着される角度調整アタッチメント１４は、該センサ７が下向き或いは横向きとなるよう９０°位相を変えて水平ステージ１２に取り付けられるようになっており、センサ７を下向きにした状態で、ホィール２の外表面に取り付けた周方向測定用ターゲット１９に対向させその変位を測定したり、或いはセンサ７を横向きにした状態で、ホィール２の外表面に対向させその変位を測定できるようにしてある。又、同様に、前記センサ８が装着される角度調整アタッチメント１８は、該センサ８が下向き或いは横向きとなるよう９０°位相を変えて水平ステージ１６に取り付けられるようになっており、センサ８を下向きにした状態で、ホィール２の内周面に対向させその変位を測定したり、或いはセンサ８を横向きにした状態で、ホィール２の内面に対向させその変位を測定できるようにしてある。   The angle adjustment attachment 14 to which the sensor 7 is attached is attached to the horizontal stage 12 with a 90 ° phase change so that the sensor 7 is directed downward or laterally, and the sensor 7 is directed downward. Thus, it is possible to measure the displacement by facing the circumferential measuring target 19 attached to the outer surface of the wheel 2 or to measure the displacement by facing the outer surface of the wheel 2 in a state where the sensor 7 is turned sideways. It is. Similarly, the angle adjustment attachment 18 to which the sensor 8 is mounted is attached to the horizontal stage 16 with the phase shifted by 90 ° so that the sensor 8 faces downward or sideways, and the sensor 8 faces downward. In such a state, the displacement is measured by making it face the inner peripheral surface of the wheel 2, or the displacement can be measured by making the sensor 8 face to face the inner surface of the wheel 2.

次に、上記図示例の作用を説明する。   Next, the operation of the illustrated example will be described.

ホィール２の変位基準点Ｏに対する各部の変位を求める際には、ホィール２を取付シャフト３の先端部に対し、図示していないボルト・ナットを用いて取り付け、先ず、ホィール２に対し荷重付与装置４によって荷重を付与しない無負荷の状態で、センサ７，８の位置調整を行って該センサ７，８をホィール２の外表面並びに内周面の所定箇所に対向させ、その箇所における変位基準点Ｏを原点とする座標が予め計測され、続いて、前記荷重付与装置４によってホィール２に嵌着されたタイヤ９に対し、その半径方向並びに軸線方向へ所望の荷重を作用させることにより、ホィール２に対して荷重を付与した状態で、前記センサ７，８によりホィール２の外表面並びに内周面の所定箇所における変位基準点Ｏを原点とする座標が計測され、該荷重付与時における座標と前記無負荷時における座標との差に基づいて、ホィール２の変位基準点Ｏに対する各部の変位が求められる。尚、前記ホィール２の外表面並びに内周面それぞれに複数箇所の変位計測点がある場合には、前述と同様の操作（即ち、一箇所について無負荷時と荷重付与時の計測を行う操作）を複数箇所に対して順次行えば高精度の鉛直ステージ１１，１５、水平ステージ１２，１６でなくとも、ステージの位置決め誤差をキャンセルした計測が行えるため、高精度の計測が行える。別のやり方としては、高精度の鉛直ステージ１１，１５、水平ステージ１２，１６を用い無負荷の状態で複数箇所全部に対し変位基準点Ｏを原点とする座標を予め計測した後、荷重を付与した状態で対応する箇所に対し変位基準点Ｏを原点とする座標を計測することもできる。   When determining the displacement of each part with respect to the displacement reference point O of the wheel 2, the wheel 2 is attached to the distal end portion of the mounting shaft 3 using bolts and nuts (not shown). First, a load applying device is applied to the wheel 2. 4, in a no-load state where no load is applied, the positions of the sensors 7 and 8 are adjusted so that the sensors 7 and 8 are opposed to predetermined positions on the outer surface and the inner peripheral surface of the wheel 2, and a displacement reference point at that position Coordinates having O as the origin are measured in advance, and then, by applying a desired load in the radial direction and the axial direction to the tire 9 fitted to the wheel 2 by the load applying device 4, the wheel 2 In the state where a load is applied to the sensor, the sensors 7 and 8 measure the coordinates with the displacement reference point O at a predetermined position on the outer surface and the inner peripheral surface of the wheel 2 as the origin, Based on the difference between the coordinates at the time of coordinates and the no-load at heavy granted, each part of the displacement is determined with respect to the displacement reference point O of the wheel 2. In addition, when there are a plurality of displacement measurement points on each of the outer surface and the inner peripheral surface of the wheel 2, the same operation as described above (that is, an operation for performing measurement when no load is applied and when a load is applied). Are sequentially performed on a plurality of locations, even if the vertical stages 11 and 15 and the horizontal stages 12 and 16 are not accurate, the measurement can be performed with cancellation of the positioning error of the stage, so that highly accurate measurement can be performed. Another method is to use high-precision vertical stages 11 and 15 and horizontal stages 12 and 16 to measure the coordinates with the displacement reference point O as the origin for all of a plurality of locations in an unloaded state, and then apply a load. In this state, it is possible to measure the coordinates with the displacement reference point O as the origin for the corresponding location.

ここで、前記ホィール２はその変位基準点Ｏが取付シャフト３の先端部に位置するよう取り付けてあり、且つセンサ７，８は取付シャフト３の先端部から延出させた支持アーム５，６に対して配設してあるため、ホィール２に対する荷重付与に伴って取付シャフト３がたとえ変形し、図４及び図５に示されるような軸たわみが発生してホィール２の変位基準点Ｏが移動したとしても、該ホィール２の変位基準点Ｏに対するセンサ７，８の相対位置は変化せず、取付シャフト３の変形をホィール２自体の変形と切り離して無視することが可能となり、この結果、前記センサ７，８によって計測されるホィール２の各部の変位は、あくまでもその変位基準点Ｏに対するものとなり、計測精度が高められることとなる。   Here, the wheel 2 is mounted such that its displacement reference point O is positioned at the tip of the mounting shaft 3, and the sensors 7 and 8 are attached to the support arms 5 and 6 extended from the tip of the mounting shaft 3. Therefore, the mounting shaft 3 is deformed as the load is applied to the wheel 2, and the shaft deflection as shown in FIGS. 4 and 5 occurs to move the displacement reference point O of the wheel 2. Even so, the relative positions of the sensors 7 and 8 with respect to the displacement reference point O of the wheel 2 do not change, and the deformation of the mounting shaft 3 can be disregarded separately from the deformation of the wheel 2 itself. The displacement of each part of the wheel 2 measured by the sensors 7 and 8 is only relative to the displacement reference point O, and the measurement accuracy is improved.

こうして、ホィール２に対する荷重付与に伴う取付シャフト３の変形の影響を受けなくすることができ、計測精度の向上を図り得る。   Thus, it is possible to eliminate the influence of the deformation of the mounting shaft 3 accompanying the load application to the wheel 2 and to improve the measurement accuracy.

尚、本発明のホィール変位計測装置は、上述の図示例にのみ限定されるものではなく、本発明の要旨を逸脱しない範囲内において種々変更を加え得ることは勿論である。   Note that the wheel displacement measuring device of the present invention is not limited to the above-described illustrated examples, and it is needless to say that various changes can be made without departing from the gist of the present invention.
