Abstract

<P>PROBLEM TO BE SOLVED: To solve such problems of a twin roller chassis dynamometer that it is poor in strength for large-size cars, and slipping occurs between a tire and a free roller when setting a car. <P>SOLUTION: A reinforcement beam is disposed between support bases for supporting the free roller, so as to be positioned at the lower part of the free roller. An opening is formed in the reinforcement beam, and a cylinder mechanism is fixed to the opening, and a stopper section is disposed at the head of its movable part. This stopper section presses and fixes the free roller from below when setting the car, thereby preventing the slipping from occurring between the tire and the free roller. Furthermore, since the position of the opening in the reinforcement beam is in the form of an inverted trapezoid, operations of other link mechanisms are not obstructed. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

本発明は、ツインローラシャシーダイナモメータに係り、特にツインローにおけるフリーローラのストッパ装置に関するものである。   The present invention relates to a twin roller chassis dynamometer, and more particularly to a stopper device for a free roller in a twin row.

ツインローラシャシーダイナモメータとしては、特許文献１のものが公知となっている。ツインローラシャシーダイナモメータは、図４及び図５で示すように被試験車両のタイヤで回動されるロードローラＲＬとフリーローラＲＦを有し、ロードローラＲＬはダイナモメータに連結されている。フリーローラＲＦは軸受アーム３に軸受を介して回動自在に取り付けられ、この軸受アーム３は支持台４とは枢軸５を介して高さ方向に調節可能に取り付けられ、高さ方向に調節することによりロードローラＲＬとフリーローラＲＦ間にかかる分荷重を調節するよう構成される。   As a twin roller chassis dynamometer, the one disclosed in Patent Document 1 is known. As shown in FIGS. 4 and 5, the twin roller chassis dynamometer has a load roller RL and a free roller RF that are rotated by the tire of the vehicle under test, and the load roller RL is connected to the dynamometer. The free roller RF is rotatably attached to the bearing arm 3 via a bearing. The bearing arm 3 is attached to the support base 4 so as to be adjustable in the height direction via the pivot 5, and is adjusted in the height direction. Thus, the load applied between the load roller RL and the free roller RF is adjusted.

６は押上装置で、被試験車両の設置時にタイヤがローラＲＬ、ＲＦ間に落ち込まないよう動作させて各ローラの頂上が略同じ高さとなるよう車両をセットする。
７はリンク機構、８はサーボモータで、このサーボモータ８を制御することによりリンク機構７が動作する。この動作により枢軸５を支点として軸受アーム３が回動してフリーローラＲＦの位置調整を行い、要求するテスト路面の摩擦係数を得る。９はローラロック装置で、被試験車両の搬入時に車両の駆動輪がスリップしないようロードローラＲＬをロックする。
特開２０００−３４６７５２号公報 Reference numeral 6 denotes a push-up device that operates so that the tire does not fall between the rollers RL and RF when the vehicle under test is installed, and sets the vehicle so that the tops of the rollers are substantially at the same height.
Reference numeral 7 denotes a link mechanism, and reference numeral 8 denotes a servo motor. By controlling the servo motor 8, the link mechanism 7 operates. By this operation, the bearing arm 3 is rotated about the pivot 5 as a fulcrum, and the position of the free roller RF is adjusted, and the required friction coefficient of the test road surface is obtained. A roller lock device 9 locks the road roller RL so that the driving wheel of the vehicle does not slip when the vehicle under test is carried in.
JP 2000-346752 A

図４で示すようなツインローラシャシーダイナモメータにおいては、ロードローラＲＬ側にはローラロック装置９が存在しているためローラ固定が可能であるが、フリーローラＲＦ側は摩擦係数の変化を模擬する機能を実現している機構上、ロック装置が設けられていない。
ところで、近年の四輪駆動車の増加と大型化により、従来のツインローラシャシーダイナモメータでは、被試験車両の搬入時にフリーローラＲＦとのスリップ現象が発生し、且つ大型車の荷重によりフリーローラＲＦ側の強度不足が発生している。 In the twin roller chassis dynamometer as shown in FIG. 4, the roller lock device 9 exists on the load roller RL side, so that the roller can be fixed, but the free roller RF side simulates the change of the friction coefficient. No locking device is provided on the mechanism realizing the function.
By the way, due to the recent increase in the number of four-wheel drive vehicles and the increase in size, the conventional twin roller chassis dynamometer causes a slip phenomenon with the free roller RF when the vehicle under test is loaded, and the free roller RF due to the load of the large vehicle. There is a lack of strength on the side.

そこで、本発明が目的とするところは、機能上の制約を有するフリーローラ側の補強とロック機構を備えたストッパ装置を提供することにある。   Accordingly, an object of the present invention is to provide a stopper device provided with a reinforcing and locking mechanism on the free roller side having functional restrictions.

本発明は、支持台を介して回動並びに揺動自在にフリーローラを設け、両側の支持台間にフリーローラの位置調整用のリンク機構を有するツインローラシャシーダイナモメータにおいて、
前記支持台間に、フリーローラの下部に位置させて補強梁を設け、この補強梁に可動部を有するシリンダ機構を固定し、この可動部の先端にストッパ部を設け、このストッパ部によりフリーローラと接合、開放自在に構成したことを特徴としたものである。 The present invention provides a twin-roller chassis dynamometer having a free roller that can be rotated and swung via a support base, and a link mechanism for adjusting the position of the free roller between the support bases on both sides.
A reinforcing beam is provided between the support bases at the lower portion of the free roller, a cylinder mechanism having a movable portion is fixed to the reinforcing beam, and a stopper portion is provided at the tip of the movable portion. It is characterized in that it can be joined and opened freely.

また、本発明は、前記補強梁に逆台形状部を形成し、この逆台形状部に孔を穿設して前記シリンダ機構を固着し、シリンダ機構の可動部先端に固定されたストッパ部は、逆台形状部とフリーローラ間に形成された空間で可動自在に設けたことを特徴としたものである。   In the present invention, an inverted trapezoidal portion is formed in the reinforcing beam, a hole is formed in the inverted trapezoidal portion to fix the cylinder mechanism, and a stopper portion fixed to the tip of the movable portion of the cylinder mechanism is Further, it is characterized in that it is movably provided in a space formed between the inverted trapezoidal portion and the free roller.

さらに、本発明は、前記ストッパ部は、前記フリーローラとの接触面を樹脂製のブレーキ材で形成したことを特徴としたものである。   Furthermore, the present invention is characterized in that the stopper portion is formed of a resin brake material on a contact surface with the free roller.

以上のとおり、本発明によれば、フリーローラの下部に位置させて補強梁を設け、且つストッパ部によって固定できるようにしたことから、被試験車両が大型となっても強度的には十分対応できるものである。また、フリーローラはストッパ部による固定で被試験車両のセッテングが容易に可能となるものである。   As described above, according to the present invention, the reinforcing beam is provided at the lower portion of the free roller and can be fixed by the stopper portion. It can be done. In addition, the free roller can be easily set by a fixed stopper.

図１は、本発明の実施例を示す斜視図、図２はストッパ装置の部分正面図で、図４及び図５と同一部分、若しくは相当部分に同一符合を付してその説明を省略する。１０は補強梁で、この補強梁１０は一部に逆台形状部１０ａを形成してその両端は軸受アーム３に固着される。逆台形状部１０ａには孔１０ｂが穿設され、その孔にシリンダ機構１１の一端が固着されている。したがって、このシリンダ機構１１は補強梁１０と一体的に設けられ、軸受アーム３の揺動時には補強梁１０と共に揺動する。   FIG. 1 is a perspective view showing an embodiment of the present invention, and FIG. 2 is a partial front view of a stopper device. The same or corresponding parts as those in FIGS. Reference numeral 10 denotes a reinforcing beam. The reinforcing beam 10 is partially formed with an inverted trapezoidal portion 10 a and both ends thereof are fixed to the bearing arm 3. A hole 10b is formed in the inverted trapezoidal portion 10a, and one end of the cylinder mechanism 11 is fixed to the hole. Therefore, the cylinder mechanism 11 is provided integrally with the reinforcing beam 10 and swings with the reinforcing beam 10 when the bearing arm 3 swings.

シリンダ機構１１は図３で示すように可動部１１ａが補強梁１０とフリーローラＲＦとの間に突出してその先端にストッパ部１２が固着され、図示省略された液圧機構などによって可動部１１ａは駆動される。ストッパ部１２は、可動部１１ａが液圧などによって押上げられたときフリーローラＲＦと接触するように構成され、そのために、フリーローラＲＦとの接触部分側は樹脂製などのブレーキ材１２ａよりなっており、可動部１１ａ側は金属部１２ｂなどによって構成されている。   As shown in FIG. 3, in the cylinder mechanism 11, the movable part 11a protrudes between the reinforcing beam 10 and the free roller RF, and the stopper part 12 is fixed to the tip thereof. The movable part 11a is Driven. The stopper portion 12 is configured to come into contact with the free roller RF when the movable portion 11a is pushed up by a hydraulic pressure or the like. For this reason, the contact portion side with the free roller RF is made of a brake material 12a made of resin or the like. The movable part 11a side is constituted by a metal part 12b or the like.

なお、可動部１１ａを有するシリンダ機構は、左右の支持台４の間に設置されているリンク機構７と併設されることから、動作時には互いに干渉し合うのを防止しなければならない。このため、逆台形状部１０ａの形成位置は、ここでは中心位置に対して図面左側に寄せた位置に設けられ、リンク機構７のパッド７ａとの接触を防止している。   In addition, since the cylinder mechanism having the movable portion 11a is provided with the link mechanism 7 installed between the left and right support bases 4, it must be prevented from interfering with each other during operation. For this reason, the formation position of the inverted trapezoidal portion 10a is provided here at a position close to the left side of the drawing with respect to the center position to prevent contact with the pad 7a of the link mechanism 7.

次に動作を説明する。
被試験車両の搬入に先立って、従来と同様にローラロック装置９によりロードローラＲＬをロックする。その後、本発明ではシリンダ機構を駆動して可動部１１ａを上方に押上げてストッパ部のブレーキ材１２ａによりフリーローラＲＦの下方から圧接してその回動を固定する。したがって、搬入された時の被試験車両のタイヤとローラ間でのスリップ現象は防止され、良好状態で車両のセットが可能となる。 Next, the operation will be described.
Prior to carrying in the vehicle under test, the load roller RL is locked by the roller lock device 9 as in the prior art. After that, in the present invention, the cylinder mechanism is driven to push up the movable portion 11a, and is pressed from below the free roller RF by the brake member 12a of the stopper portion to fix its rotation. Therefore, the slip phenomenon between the tire and the roller of the vehicle under test when it is carried in is prevented, and the vehicle can be set in a good state.

ローラ上への車両セット後は、押上装置６の駆動部を動作させることによってフリーローラＲＦの下方にまで下げ、押上装置６がフリーローラＲＦの動作の妨げとならないよう逃がしておく。また、シリンダ機構１１を駆動して可動部を下方に押下げることにより、フリーローラＲＦとストッパ部１２との接合を解離する。その時の可動部１１ａのストロークは短い移動距離で両者の接合状態は解除される。以降は試験手順に基づいて実行される。   After the vehicle is set on the roller, the drive unit of the push-up device 6 is operated to lower it below the free roller RF, and the push-up device 6 is released so as not to interfere with the operation of the free roller RF. Further, the cylinder mechanism 11 is driven to push the movable part downward, so that the joining of the free roller RF and the stopper part 12 is dissociated. The stroke of the movable part 11a at that time is a short movement distance, and the joining state of both is released. Thereafter, the test procedure is executed.
