Description

車両性能試験装置の車輪センタリング装置Wheel centering device for vehicle performance test equipment
　本発明は、試験車両の駆動輪を一軸ドラム(以下、ドラム）上に載せて、該ドラムで上記駆動輪を回転させて、試験車両の各種性能試験を行なうシャシーダイナモメータ等の車両性能試験装置において、試験車両の駆動輪を上記ドラムの真上に載せるための車輪センタリング装置に関するものである。 The present invention relates to a vehicle performance test apparatus such as a chassis dynamometer for performing various performance tests on a test vehicle by placing the drive wheels of a test vehicle on a uniaxial drum (hereinafter referred to as a drum) and rotating the drive wheels with the drum. The present invention relates to a wheel centering device for placing a driving wheel of a test vehicle directly above the drum.
　シャシーダイナモメータにおいて、試験車両の試験を正確に行なうためには、試験車両の駆動輪を上記ドラムの真上、即ち、上記駆動輪の回転中心と上記ドラムの回転中心を結ぶ線が垂直となるように配置する必要がある。車輪センタリング装置は、上述の要求に応えるものである。 In the chassis dynamometer, in order to accurately test the test vehicle, the drive wheel of the test vehicle is directly above the drum, that is, the line connecting the rotation center of the drive wheel and the rotation center of the drum is vertical. It is necessary to arrange so that. The wheel centering device meets the above requirements.
　図７～図９に示すように、車輪センタリング装置１０１として、上記試験車両の駆動輪１０２を載せるドラム１０３の軸線を通る鉛直線ＶＬの前後に配置した位置決め部材としての前後一対のローラ１０４，１０５と、これら一対のローラ１０４，１０５を前後方向に移動させて上記駆動輪を押圧する駆動機構１０６，１０７と、上記ローラ１０４，１０５と上記駆動輪１０２とが所定の圧力で接触した場合にその旨を示す接触信号を出力する接触センサ（図示省略）と、上記ローラ１０４，１０５の位置を検出する位置センサ（図示省略）と、上記駆動機構１０６，１０７を制御して上記各ローラ１０４，１０５を上記駆動輪１０２の軸線を上記鉛直線ＶＬ上に位置付け可能な作動位置と、上記駆動輪１０２に接触しない非作動位置との間で移動させる制御機構１０８と、を備えていて、上記制御機構１０８は、上記接触信号が出力された時点での位置センサから得られる位置を上記作動位置として設定する構成になっている。 As shown in FIGS. 7 to 9, as the wheel centering device 101, a pair of front and rear rollers 104, 105 as positioning members arranged before and after a vertical line VL passing through the axis of the drum 103 on which the driving wheel 102 of the test vehicle is placed. When the driving mechanisms 106 and 107 that move the pair of rollers 104 and 105 in the front-rear direction to press the driving wheel and the rollers 104 and 105 and the driving wheel 102 come into contact with each other with a predetermined pressure, A contact sensor (not shown) that outputs a contact signal indicating the effect, a position sensor (not shown) that detects the positions of the rollers 104 and 105, and the drive mechanisms 106 and 107 to control the rollers 104 and 105. Between an operating position where the axis of the driving wheel 102 can be positioned on the vertical line VL and a non-operating position where the driving wheel 102 does not contact the driving wheel 102. In a control mechanism 108 for moving, it has a, the control mechanism 108, the position obtained from the position sensor at a time when the contact signal is outputted has a configuration to set as the operating position.
　図８に示すように、上記車輪センタリング装置１０１は、上記駆動輪１０２が上記ドラム１０３の周面およびピットカバー面（車両走行床面）１０９のドラム用の開口部１１０の周縁部に接触したときに、上記駆動機構１０６，１０７のモータを駆動して、一対のローラ１０４，１０５を駆動輪１０２に向かってスライドさせる。 As shown in FIG. 8, the wheel centering device 101 is configured such that the driving wheel 102 contacts the peripheral surface of the drum 103 and the peripheral portion of the drum opening 110 on the pit cover surface (vehicle traveling floor surface) 109. In addition, the motors of the drive mechanisms 106 and 107 are driven to slide the pair of rollers 104 and 105 toward the drive wheel 102.
　上記駆動輪１０２に近い一方（駆動輪後方）のローラ１０５が駆動輪１０２に接触すると上記モータの負荷が増大し、該モータへの供給電流が増加する。上記接触センサは、上記供給電流が所定値以上になったことを検知することでローラ１０５が上記駆動輪１０２に接触したことを検知して接触信号を出力する。 When one of the rollers 105 close to the drive wheel 102 (the rear of the drive wheel) comes into contact with the drive wheel 102, the load on the motor increases and the supply current to the motor increases. The contact sensor detects that the roller 105 has contacted the driving wheel 102 by detecting that the supply current has become a predetermined value or more, and outputs a contact signal.
　上記駆動輪１０２に接触している一方のローラ１０５のスライドに伴って上記駆動輪１０２は、上記ドラム１０３の頂上部に向かって移動する。 The driving wheel 102 moves toward the top of the drum 103 as one roller 105 that is in contact with the driving wheel 102 slides.
　そして、図９に示すように、上記駆動輪１０２がドラム１０３の頂上部に達すると他方（駆動輪前方）のローラ１０４も上記駆動輪１０２の他側面に接触して該駆動輪１０２を支持する。このとき、他側の接触センサも接触を検知して接触信号を出力する。ローラ１０４側の接触センサと、ローラ１０５側の接触センサの両方から接触信号が出力されたときにローラ１０４，１０５のスライドを停止させて、センタリング動作は終了する（例えば、特許文献１）。 As shown in FIG. 9, when the driving wheel 102 reaches the top of the drum 103, the other roller 104 (front of the driving wheel) also contacts the other side of the driving wheel 102 to support the driving wheel 102. . At this time, the contact sensor on the other side also detects contact and outputs a contact signal. When contact signals are output from both the contact sensor on the roller 104 side and the contact sensor on the roller 105 side, the sliding of the rollers 104 and 105 is stopped, and the centering operation ends (for example, Patent Document 1).
特開２００５－２３３６６８号公報（段落００４２～００４６、段落００６１～００６５等参照）。Japanese Patent Laying-Open No. 2005-233668 (see paragraphs 0042-0046, paragraphs 0061-0065, etc.).
　ところで、上記従来の車輪センタリング装置は、上述したように、一方のローラ１０５によって駆動輪１０２がドラム１０３の頂上部に移動して来て、該駆動輪１０２が他方のローラ１０４側の接触センサを所定の接触圧で押圧したことを検知して、センタリングを行なう構成になっていたために、駆動輪１０２の材質やスタッドレスか否か、あるいは空気圧の高低等によって、接触センサで検出される駆動輪１０２の検出位置に差異が生じる虞があるという問題点があった。 In the conventional wheel centering device, as described above, the driving wheel 102 is moved to the top of the drum 103 by one roller 105, and the driving wheel 102 detects the contact sensor on the other roller 104 side. The driving wheel 102 is detected by the contact sensor depending on the material of the driving wheel 102, whether it is studless, or whether the air pressure is high, because the centering is performed by detecting the pressing with a predetermined contact pressure. There is a problem that a difference may occur in the detection position.
　本発明の目的は、駆動輪の材質や空気圧等に関係なく正確に駆動輪の外周端の位置を検知することのできる車輪センタリング装置を提供することにある。 An object of the present invention is to provide a wheel centering device that can accurately detect the position of the outer peripheral end of a drive wheel regardless of the material, air pressure, etc. of the drive wheel.
　本発明は、ピット内に配置したドラムの頂上部をピットカバー面に設けた開口部に臨ませて上記ドラムの頂上部に試験車両の駆動輪を載せて試験車両の試験を行なう車両性能試験装置において、上記駆動輪を上記ドラムの頂上部にセンタリングする車輪センタリング装置であって、上記ドラムの軸心を通る鉛直線の前後に配置された前後一対のローラと、ローラをローラホルダによりロッドの先端部に取り付けた前後一対の電動シリンダと、上記ローラと共に上記ローラホルダに取り付けられていて駆動輪を検出する駆動輪検出センサと、上記前後一対の電動シリンダの駆動を制御する制御装置と、を備えた車輪センタリング装置において、上記駆動輪検出センサに光電センサを使用した。 The present invention relates to a vehicle performance testing apparatus for testing a test vehicle by placing a driving wheel of a test vehicle on the top of the drum with the top of the drum arranged in the pit facing an opening provided on the pit cover surface. A wheel centering device for centering the drive wheel on the top of the drum, wherein the front end of the rod is mounted by a roller holder with a pair of front and rear rollers disposed before and after a vertical line passing through the axis of the drum. A pair of front and rear electric cylinders attached to the unit, a drive wheel detection sensor that is attached to the roller holder together with the roller and detects a drive wheel, and a control device that controls the driving of the front and rear pair of electric cylinders. In the wheel centering device, a photoelectric sensor is used as the driving wheel detection sensor.
　上記光電センサを、上記ローラホルダに、上記ピットカバー面に沿わせて上記ローラと並べて略水平方向に配置した。また、上記光電センサを、上記ローラホルダに、上記ローラよりもロッドの先端側に該ロッドの移動方向に直列に並べて配置した。 The photoelectric sensor was arranged in a substantially horizontal direction along with the roller along the pit cover surface on the roller holder. Further, the photoelectric sensor is arranged on the roller holder in a line in series in the moving direction of the rod on the tip end side of the rod from the roller.
　本発明の車輪センタリング装置は、駆動輪検出センサに光電センサを使用したので、駆動輪の材質や空気圧等に関係なく駆動輪の外周端のエッジ位置を正確に検出することができる。特に、光電センサとローラを、ピットカバー面に沿わせて略水平方向に並べてローラホルダに配置したので、光電センサによる駆動輪の検出と、ローラの駆動輪の接触を略同時に行なうことができる。また、上記光電センサを、上記ローラよりもロッドの先端側に該ロッドの移動方向に直列に並べてローラホルダに配置したので、光電センサによる駆動輪の検出と、ローラの駆動輪への接触に時間差をもたせ、光電センサにより駆動輪を検出した後、所定の時間後に、ローラを駆動輪に接触させることができる。 Since the wheel centering device of the present invention uses a photoelectric sensor as the driving wheel detection sensor, the edge position of the outer peripheral end of the driving wheel can be accurately detected regardless of the material of the driving wheel, the air pressure, and the like. Particularly, since the photoelectric sensor and the roller are arranged in the roller holder along the pit cover surface in a substantially horizontal direction, the detection of the driving wheel by the photoelectric sensor and the contact of the driving wheel of the roller can be performed substantially simultaneously. Further, since the photoelectric sensor is arranged in the roller holder in series with the moving direction of the rod on the tip side of the rod from the roller, there is a time difference between detection of the driving wheel by the photoelectric sensor and contact of the roller with the driving wheel. The roller can be brought into contact with the driving wheel after a predetermined time after the driving wheel is detected by the photoelectric sensor.

　図２，図３に示すように、前後一対の電動シリンダ５，６の左右一対のロッド４，４の先端は、上記ローラホルダ３によって連結されている。上記ローラホルダ３は、上記左右一対のロッド４，４の先端部を連結している連結部２１と、該連結部２１の両端部に設けられた一対のローラ支持アーム部２２，２３と、からなっていて、これら一対のローラ支持アーム部２２，２３の間に上記ローラ２が回転自在に取り付けられている。 2 and 3, the ends of the pair of left and right rods 4 and 4 of the pair of front and rear electric cylinders 5 and 6 are connected by the roller holder 3 described above. The roller holder 3 includes a connecting portion 21 that connects the distal ends of the pair of left and right rods 4 and 4, and a pair of roller support arm portions 22 and 23 provided at both ends of the connecting portion 21. The roller 2 is rotatably mounted between the pair of roller support arm portions 22 and 23.
　ローラ支持アーム部２２，２３の上記ローラ２近傍位置には上記駆動輪検出センサとしての光電センサ７が配置されている。 A photoelectric sensor 7 serving as the driving wheel detection sensor is disposed in the vicinity of the roller 2 of the roller support arm portions 22 and 23.
　光電センサ７は、一方のローラ支持アーム部２２の内面に取り付けられた発光素子７ａと、他方のローラ支持アーム部２３の内面に上記発光素子７ａと対向させて取り付けられた受光素子７ｂと、からなっていて、上記発光素子７ａと受光素子７ｂの間に駆動輪１０２が侵入すると該駆動輪１０２により上記発光素子７ａから発射された検出光が遮断されて駆動輪１０２を検出する。 The photoelectric sensor 7 includes a light emitting element 7a attached to the inner surface of one roller support arm portion 22, and a light receiving element 7b attached to the inner surface of the other roller support arm portion 23 so as to face the light emitting element 7a. When the driving wheel 102 enters between the light emitting element 7a and the light receiving element 7b, the detection light emitted from the light emitting element 7a is blocked by the driving wheel 102 and the driving wheel 102 is detected.
　図４に拡大して示すように、ローラホルダ３の先端、即ちローラ支持アーム部２２，２３の先端は、上記ピットカバー面１０９と平行になるように水平に形成されている。ローラ支持アーム部２２，２３の先端には、ローラ２をピット内に収納したときに上記ドラム用開口部１１０の一部を閉塞する蓋板２４が取り付けられている。また、ローラホルダ３の先端には、ローラ２と光電センサ７が水平方向に並べた状態で配置されていて、光電センサ７で駆動輪１０２を検出するのと略同時にローラ２が駆動輪１０２に接触するようになっている。 4, the tip of the roller holder 3, that is, the tips of the roller support arm portions 22 and 23, is formed horizontally so as to be parallel to the pit cover surface 109. A cover plate 24 that closes a part of the drum opening 110 when the roller 2 is housed in the pit is attached to the tips of the roller support arm portions 22 and 23. In addition, the roller 2 and the photoelectric sensor 7 are arranged in the horizontal direction at the tip of the roller holder 3, and the roller 2 moves to the driving wheel 102 almost simultaneously with the detection of the driving wheel 102 by the photoelectric sensor 7. It comes to contact.
　ローラホルダ３は、移動ガイド部材２５によって上下動をガイドされる。ローラホルダ３にはアーム２６を介してリミットスイッチ操作体２７が設けられている。 The roller holder 3 is guided to move up and down by the moving guide member 25. The roller holder 3 is provided with a limit switch operating body 27 via an arm 26.
　そして、図１に実線で示すように、ローラホルダ３が下限位置（移動基準位置）まで移動すると、スイッチ操作体２７で下端リミットスイッチ２８が押圧操作されてローラホルダ３が下限位置（移動基準位置）に在ることが検知される。また、図１に２点鎖線で示すように、ローラホルダ３を上限位置まで移動させると、スイッチ操作体２７で上端リミットスイッチ２９が押圧操作され、ローラホルダ３が上限位置に在ることが検知され、ローラホルダ３の更なる移動を阻止する。なお、前後一対の電動シリンダ５，６は、ピットカバー面１０９に対するロッド４の傾斜角度θを調整可能にシリンダ保持部材３０によりピット内に取り付けられている。 1, when the roller holder 3 moves to the lower limit position (movement reference position), the lower limit switch 28 is pressed by the switch operating body 27 and the roller holder 3 is moved to the lower limit position (movement reference position). ) Is detected. Further, as shown by a two-dot chain line in FIG. 1, when the roller holder 3 is moved to the upper limit position, the upper limit switch 29 is pressed by the switch operating body 27, and it is detected that the roller holder 3 is at the upper limit position. Then, further movement of the roller holder 3 is prevented. The pair of front and rear electric cylinders 5 and 6 are mounted in the pit by a cylinder holding member 30 so that the inclination angle θ of the rod 4 with respect to the pit cover surface 109 can be adjusted.
　次に、車輪センタリング装置１の作用について説明する。先ず、試験車両の駆動輪１０２をシャシーダイナモメータのドラム１０３と、ピットカバー面１０９のドラム用の開口部１１０の周縁部の間に載せる。次に、前後一対の電動シリンダ５，６でローラホルダ３を下降させて、スイッチ操作体２７で下端リミットスイッチ２８を押圧操作して基準位置となる下限位置を検出する。 Next, the operation of the wheel centering device 1 will be described. First, the driving wheel 102 of the test vehicle is placed between the drum 103 of the chassis dynamometer and the peripheral portion of the drum opening 110 on the pit cover surface 109. Next, the roller holder 3 is lowered by the pair of front and rear electric cylinders 5 and 6, and the lower limit switch 28 is pressed by the switch operating body 27 to detect the lower limit position serving as the reference position.
　下限位置を検出したら、前後一対の電動シリンダ５，６のロッド４を上昇させる。一対の電動シリンダ５，６のロッド４を上昇させると、駆動輪１０２に近い一方の電動シリンダ、即ち駆動輪１０２の後方側の電動シリンダ６の光電センサ７が駆動輪１０２を検出するのと略同時にローラ２が駆動輪１０２に接触する。 When the lower limit position is detected, the rods 4 of the pair of front and rear electric cylinders 5 and 6 are raised. When the rods 4 of the pair of electric cylinders 5 and 6 are raised, it is almost the same as detecting the driving wheel 102 by one of the electric cylinders close to the driving wheel 102, that is, the photoelectric sensor 7 of the electric cylinder 6 on the rear side of the driving wheel 102. At the same time, the roller 2 comes into contact with the drive wheel 102.
　更に、前後一対の電動シリンダ５，６のロッド４を上昇させると、他方の電動シリンダ、即ち駆動輪１０２の前方側の電動シリンダ５の光電センサ７が駆動輪１０２を検出するのと略同時にローラ２が駆動輪１０２に接触してセンタリングが行なわれる。 Further, when the rods 4 of the pair of front and rear electric cylinders 5 and 6 are raised, the roller is substantially simultaneously with the other electric cylinder, that is, the photoelectric sensor 7 of the electric cylinder 5 on the front side of the driving wheel 102 detects the driving wheel 102. 2 is brought into contact with the drive wheel 102 for centering.
　上記センタリング終了後においても、駆動輪１０２がドラム１０３から浮き上がらない程度に、更に、前後一対の電動シリンダ５，６のロッド４、ロッドホルダ３およびローラ２を上昇させて、駆動輪１０２を所定の荷重圧でドラム１０３に圧着させる。そして、上記ローラ２を回転させて駆動輪１０２や試験車両の姿勢制御を行なう。上記駆動輪１０２がドラム１０３から浮き上がったか否かは図示省略の圧力センサによって検出する。なお、前後一対の電動シリンダ５，６は、それぞれ別々にピット内で組み付け固定されるので不可避的に両者の間には組付誤差が発生する。そして、組付位置の誤差により、ロッド４のストローク偏差を生じる場合がある。このような、場合は、前後一対の電動シリンダ５，６のロッド４のストロークの偏差を演算して、前後一対の電動シリンダ５，６のロッド４のストロークが同じになるように補正する。図５は、上記車輪センタリング装置１の動作の一例を示すフロー図を示し、付記した３１は操作盤を示す。 Even after the centering is completed, the rods 4, the rod holders 3 and the rollers 2 of the pair of front and rear electric cylinders 5 and 6 are further raised so that the drive wheels 102 do not float from the drum 103, so that the drive wheels 102 Crimp to the drum 103 with load pressure. Then, the rollers 2 are rotated to control the attitude of the drive wheels 102 and the test vehicle. Whether or not the driving wheel 102 is lifted from the drum 103 is detected by a pressure sensor (not shown). Since the pair of front and rear electric cylinders 5 and 6 are separately assembled and fixed in the pits, an assembly error is inevitably generated between them. Then, a stroke deviation of the rod 4 may occur due to an error in the assembly position. In such a case, the deviation of the stroke of the rod 4 of the pair of front and rear electric cylinders 5 and 6 is calculated and corrected so that the stroke of the rod 4 of the pair of front and rear electric cylinders 5 and 6 becomes the same. FIG. 5 is a flow chart showing an example of the operation of the wheel centering device 1, and 31 is an operation panel.
　図６は本発明の車輪センタリング装置１の他の実施例を示す。この実施例において、駆動輪１０２の前方側に位置する光電センサ７は、ローラ２よりもロッドホルダ３の先端側に位置するように、ロッド４のスライド方向の前方に直列にロッドホルダ３に配置されている。そして、光電センサ７による駆動輪１０２の検出と、ローラ２の駆動輪１０２への接触に時間差をもたせ、光電センサ７により駆動輪１０２を検出した後、所定の時間後に、ローラ２を駆動輪１０２に接触させることができる。その他の構成、作用効果は、上記基本となる実施例の場合と同じであるので重複する説明は省略する。 FIG. 6 shows another embodiment of the wheel centering device 1 of the present invention. In this embodiment, the photoelectric sensor 7 located on the front side of the drive wheel 102 is arranged in the rod holder 3 in series in the slide direction of the rod 4 so as to be located on the tip side of the rod holder 3 relative to the roller 2. Has been. A time difference is provided between the detection of the driving wheel 102 by the photoelectric sensor 7 and the contact of the roller 2 with the driving wheel 102, and after detecting the driving wheel 102 by the photoelectric sensor 7, the roller 2 is moved to the driving wheel 102 after a predetermined time. Can be contacted. Other configurations and functions and effects are the same as those in the above-described basic embodiment, and thus redundant description is omitted.
　上記実施例においては、本発明の車輪センタリング装置を、シャシーダイナモメータにおいて一軸ドラムに試験車両の駆動輪をセンタリングする場合を例にとって説明したが、シャシーダイナモメータに限らず広く車両性能試験装置において試験車両の駆動輪等をセンタリングする場合に用いられる。 In the above embodiment, the wheel centering device of the present invention has been described by taking as an example the case where the driving wheel of the test vehicle is centered on the single-axis drum in the chassis dynamometer. This is used when centering driving wheels of a vehicle.
