本発明は、シャーシダイナモメータにおいて自動二輪車の固定に用いられる自動二輪車固定装置に関するものである。   The present invention relates to a motorcycle fixing device used for fixing a motorcycle in a chassis dynamometer.

シャーシダイナモメータにおいて自動二輪車の固定に用いられる自動二輪車固定装置としては、ローラ上に駆動輪である後輪を載せ置き、ハンドルをフレームに対して固定した自動二輪車の前輪の下部を左右から板状部材で挟み込んで固定する自動二輪車固定装置が知られている。   As a motorcycle fixing device used for fixing a motorcycle in a chassis dynamometer, a rear wheel as a driving wheel is placed on a roller, and a lower part of a front wheel of the motorcycle with a handle fixed to a frame is formed in a plate shape from the left and right. 2. Description of the Related Art A motorcycle fixing device that is sandwiched and fixed by members is known.

前述した自動二輪車の前輪の下部を左右から挟み込んで固定する自動二輪車固定装置によれば、左右から前輪を挟みつける板状部材と前輪と間の摩擦力のみによって前輪を固定しようとするものであるために、自動二輪車の前後方向等については、必ずしも充分に強固に前輪を固定することができないという問題があった。   According to the motorcycle fixing device that clamps and fixes the lower part of the front wheel of the motorcycle described above from the left and right, the front wheel is fixed only by the frictional force between the plate-like member that clamps the front wheel from the left and right and the front wheel. For this reason, there has been a problem that the front wheels cannot be fixed sufficiently firmly in the longitudinal direction of the motorcycle.

そこで、本発明は、より強固に自動二輪車の従輪を固定することのできる、シャシーダイナモメータの自動二輪車固定装置を提供することを課題とする。   Accordingly, an object of the present invention is to provide a chassis dynamometer motorcycle fixing device that can more securely fix a slave wheel of a motorcycle.

前記課題達成のために、本発明は、ピット内に配置されたシャシーダイナモメータのローラ上に駆動輪が載置された自動二輪車の従輪を固定する自動二輪車固定装置を、ピットに固定されるベース部と、前記ベース部に支持された、前記従輪のリムの内周側の面の左右二カ所と前記従輪のタイヤの外周側の面の一カ所との計三カ所を少なくとも含む複数箇所に接して、従輪を挟持するクランプ装置とより構成したものである。   In order to achieve the above object, the present invention provides a base for fixing a motorcycle fixing device for a motorcycle, which fixes a slave wheel of a motorcycle in which driving wheels are mounted on rollers of a chassis dynamometer arranged in the pit. And a plurality of locations including at least three locations, the left and right locations on the inner peripheral surface of the rim of the slave wheel, and one location on the outer peripheral surface of the tire of the secondary wheel, supported by the base portion. And a clamping device for clamping the slave wheel.

このようなシャシーダイナモメータのクランプ装置によれば、前記従輪のリムの内周側の面の左右二カ所と前記従輪のタイヤの外周側の面の一カ所との計三カ所を少なくとも含む複数箇所を挟持することにより自動二輪車の従輪を固定するので、自動二輪車の前後方向を含む各方向について、従輪とクランプ装置との掛合による拘束力をも用いた摩擦力のみによらない従輪の固定が実現される。したがって、左右から前輪を挟みつける板状部材と前輪と間の摩擦力のみによって前輪を固定する場合に比べ、より強固に自動二輪車の従輪を固定することができる。   According to such a chassis dynamometer clamping device, a plurality of locations including at least three locations in total, that is, two locations on the inner circumferential side of the rim of the secondary wheel and one location on the outer circumferential side of the tire of the secondary wheel. Since the slave wheel of the motorcycle is fixed by clamping the motorcycle, the slave wheel can be fixed not only by the frictional force using the binding force of the slave wheel and the clamping device in each direction including the front-rear direction of the motorcycle. Is done. Therefore, compared with the case where the front wheel is fixed only by the frictional force between the plate-like member that sandwiches the front wheel from the left and right and the front wheel, the slave wheel of the motorcycle can be fixed more firmly.

ここで、このようなシャシーダイナモメータの自動二輪車固定装置は、前記クランプ装置を、前記従輪の回転軸と等しい高さにおいて前記従輪を挟持可能なように、前記ベース部に対する高さを調整可能に当該ベース部で支持するように構成することが好ましい。
このように従輪の回転軸と等しい高さにおいて前記従輪を固定することにより、自動二輪車の前後方向の力に対して、より安定的に当該従輪を固定することができるようになる。
また、前記自動二輪車の従輪が当該自動二輪車の前輪である場合には、以上のシャシーダイナモメータの自動二輪車固定装置は、より具体的には、前記クランプ装置を、左右一対の開閉する、開いた状態において前記自動二輪車の後方方向に開いた開口を形成する爪と、記一対の爪の間に配置された、前記自動二輪車の前後方向に移動可能な背板とを備えて構成するようにしてもよい。ここで、前記従輪の回転軸と等しい高さにおいて前記従輪を挟持可能なように、前記クランプ装置の前記ベース部に対する高さが調整され、かつ、前記一対の爪が開いた状態において、当該一対の爪の間に前記自動二輪車の後方方向から進入された前記従輪のタイヤの前部の外周側の面に、前記背板は当接して前記自動二輪車の前方方向へ移動するものであり、前記一対の爪は、前記背板の前記自動二輪車の前方方向への移動に連動して閉じて、それぞれ進入した前記従輪の前部のリムの内周側の面の左右二カ所に各々当接するものである。また、このようにクランプ装置を構成する場合には、自動二輪車固定装置に、さらに、前記従輪のタイヤの前部の外周側の面に当接して自動二輪車の前方方向へ移動した前記背板を固定する固定機構を設けることが好ましい。
Here, the motorcycle dynamometer of such a chassis dynamometer can adjust the height relative to the base portion so that the clamping device can clamp the slave wheel at a height equal to the rotational axis of the slave wheel. It is preferable to constitute so as to be supported by the base portion.
By fixing the slave wheel at a height equal to the rotational axis of the follower wheel in this way, the slave wheel can be more stably fixed against the force in the front-rear direction of the motorcycle.
Further, when the slave wheel of the motorcycle is the front wheel of the motorcycle, the motorcycle fixing device of the above chassis dynamometer more specifically, the clamp device is opened to open and close a pair of left and right. A claw that forms an opening that opens in the rearward direction of the motorcycle in a state, and a back plate that is disposed between the pair of claws and that is movable in the front-rear direction of the motorcycle. Also good. Here, the height of the clamp device with respect to the base portion is adjusted so that the slave wheel can be clamped at a height equal to the rotation axis of the slave wheel, and the pair of claws are opened. The back plate is in contact with the outer peripheral surface of the front tire of the slave wheel that has entered from the rear direction of the motorcycle between the claws of the motorcycle, and moves in the forward direction of the motorcycle. The pair of claws are closed in conjunction with the movement of the motorcycle in the forward direction of the motorcycle, and abut against the two left and right sides of the inner peripheral surface of the front rim of the slave wheel, respectively It is. Further, when the clamp device is configured in this way, the back plate that has moved in the forward direction of the motorcycle in contact with the outer peripheral surface of the front portion of the tire of the slave wheel is attached to the motorcycle fixing device. It is preferable to provide a fixing mechanism for fixing.

これらのようにすることにより、作業者は自動二輪車の前輪を爪の間に押し込むだけの簡単な作業で、当該前輪を固定装置で固定することができるようになる。   By doing so, the operator can fix the front wheel with the fixing device by a simple operation of pushing the front wheel of the motorcycle between the claws.

以上のように、本発明によれば、より強固に自動二輪車の従輪を固定することができる。   As described above, according to the present invention, the slave wheel of the motorcycle can be fixed more firmly.

以下、本発明の一実施形態について説明する。
図1に、本実施形態に係るシャシーダイナモメータの構成を模式的に示す。
図示するようにシャシーダイナモメータは、試験車両の走行面となるピット10の上面に設けた開口に、ローラ11の天頂部が露出するようにピット10内に配置される。そして、このようなシャシーダイナモメータを用いた自動二輪車の試験は、ハンドルをフレームに対して固定した自動二輪車の駆動輪である後輪をローラ11の天頂部に載置すると共に、ピット10に対して固定した固定装置12で自動二輪車の前輪を固定した上で、ローラ11に連結した動力計で自動二輪車の各種特性を測定することにより行う。
Hereinafter, an embodiment of the present invention will be described.
FIG. 1 schematically shows the configuration of the chassis dynamometer according to this embodiment.
As shown in the drawing, the chassis dynamometer is disposed in the pit 10 so that the top of the roller 11 is exposed in an opening provided on the upper surface of the pit 10 that is a running surface of the test vehicle. A motorcycle test using such a chassis dynamometer is performed by placing a rear wheel, which is a driving wheel of a motorcycle having a handle fixed to a frame, on the top of the roller 11 and against the pit 10. This is done by fixing the front wheels of the motorcycle with the fixing device 12 fixed in place and measuring various characteristics of the motorcycle with a dynamometer connected to the roller 11.

以下、このように自動二輪車の前輪の固定に用いられる固定装置12の詳細について説明する。
まず、図2a、bに固定装置12の構成を示す。なお、図2aは固定装置12の上面を、図2bは固定装置12の側面を表している。
図示するように、固定装置12は、ピット10に対してボルトなどによって固定されるベース111、ベース111に垂直に立てられた二本のガイドポール112、ガイドポール112に対して固定される昇降ステージ113、開閉可能に設けた二つの爪1141を持つ、昇降ステージ113の上に配置されたクランプ114、昇降ステージ113の上に配置した、クランプ114を開閉するためのモータ115、クランプ114と連結された背板付ナット116とを備えている。
Hereinafter, details of the fixing device 12 used for fixing the front wheels of the motorcycle will be described.
First, the structure of the fixing device 12 is shown in FIGS. 2A shows the upper surface of the fixing device 12, and FIG. 2B shows the side surface of the fixing device 12.
As shown in the figure, the fixing device 12 includes a base 111 fixed to the pit 10 by bolts, two guide poles 112 standing vertically to the base 111, and a lifting stage fixed to the guide pole 112. 113, which has two claws 1141 that can be opened and closed, is connected to a clamp 114 disposed on the lifting stage 113, a motor 115 disposed on the lifting stage 113, and a clamp 114 for opening and closing the clamp 114. And a back plate nut 116.

ここで、昇降ステージ113は、二本のガイドポール112に沿って上下方向に移動することができると共に、上下方向の任意位置においてガイドポール112に対して固定できるように設けられている。また、モータ115は、昇降ステージ113の上に形成したガイド溝1131に沿って、自動二輪車の前後方向に所定範囲内でスライド可能に設けられている。   Here, the elevating stage 113 is provided so that it can move in the vertical direction along the two guide poles 112 and can be fixed to the guide pole 112 at an arbitrary position in the vertical direction. The motor 115 is provided so as to be slidable within a predetermined range in the front-rear direction of the motorcycle along a guide groove 1131 formed on the elevating stage 113.

また、二つの爪1141は、それぞれ昇降ステージ113に固定された軸1132を回転軸として回転することにより開閉する。また、二つの爪1141と背板付ナット116は、連結軸1161で当該連結軸1161を回転軸として回動可能に連結されている。そして、モータ115のモータ軸は雄ねじ1151となっており、この雄ねじ1151が背板付ナット116に螺合している。   The two claws 1141 are opened and closed by rotating about a shaft 1132 fixed to the elevating stage 113, respectively. The two claws 1141 and the nut 116 with the back plate are connected by a connecting shaft 1161 so as to be rotatable about the connecting shaft 1161 as a rotating shaft. The motor shaft of the motor 115 is a male screw 1151, and this male screw 1151 is screwed into the nut 116 with the back plate.

次に、このような固定装置12の動作について説明する。
まず、自動二輪車を固定する場合、作業者は、固定しようとする自動二輪車に応じた適当なピット10上の位置に固定装置12のベース111を固定し、図2cに示すように固定しようとする自動二輪車の前輪200の回転軸高さとクランプ114の高さが一致するように、昇降ステージ113の高さを調整した上で、昇降ステージ113をガイドポール112に固定する。
Next, the operation of the fixing device 12 will be described.
First, when fixing a motorcycle, the operator fixes the base 111 of the fixing device 12 at an appropriate position on the pit 10 corresponding to the motorcycle to be fixed, and attempts to fix the base as shown in FIG. 2c. The elevating stage 113 is fixed to the guide pole 112 after adjusting the height of the elevating stage 113 so that the rotational axis height of the front wheel 200 of the motorcycle matches the height of the clamp 114.

次に、作業者は、図3a1、b1、c1に示すように、雄ねじ1151の先端部のみが背板付ナット116に螺号し、モータ115が自動二輪車側にスライドしている状態とすることにより、クランプ114を開いた状態とした上で、自動二輪車の前輪200の前部を背板付ナット116の前輪側端に設けた背板部分に当接させてクランプ114の内側に押し込む。   Next, as shown in FIGS. 3 a 1, b 1, and c 1, the operator makes a state in which only the front end portion of the male screw 1151 is screwed to the nut 116 with the back plate, and the motor 115 is slid to the motorcycle side. After the clamp 114 is opened, the front portion of the front wheel 200 of the motorcycle is brought into contact with the back plate portion provided on the front wheel side end of the nut 116 with the back plate and pushed into the clamp 114.

なお、図3において、a1、a2、a3は固定装置12の上方よりみた状態を、b1、b2、b3は固定装置12の側方よりみた状態を、c1、c2、c3は側方よりみたモータ115、雄ねじ1151、背板付ナット116の位置と相互の関係を模式的に示したものである。   In FIG. 3, a1, a2, and a3 are viewed from above the fixing device 12, b1, b2, and b3 are viewed from the side of the fixing device 12, and c1, c2, and c3 are viewed from the side. 115, the positions of the male screw 1151 and the back plate nut 116 and their relations are schematically shown.

さて、作業者が、図3a1、b1、c1に示す状態において、自動二輪車の前輪200の前部を背板付ナット116の背板部分に当接させてクランプ114の内側に押し込むと、図3a2、b2、c2に示すように、背板付ナット116と雄ねじ1151とモータ115が、そのまま前輪200が押し込まれた方向に移動し、クランプ114の二つの爪1141が軸1132を中心に回転し閉じる。そして、この二つの爪1141と背板付ナット116の背板部分によって、前輪200が、リム二カ所と前輪200のタイヤ前面との計三カ所で挟み込まれる。   Now, in the state shown in FIGS. 3 a 1, b 1 and c 1, when the front part of the front wheel 200 of the motorcycle is brought into contact with the back plate part of the nut 116 with the back plate and pushed into the clamp 114, FIG. As shown in b2 and c2, the nut 116 with the back plate, the male screw 1151, and the motor 115 move in the direction in which the front wheel 200 is pushed in, and the two claws 1141 of the clamp 114 rotate around the shaft 1132 and close. The front wheel 200 is sandwiched between the two claws 1141 and the back plate portion of the nut 116 with the back plate at a total of three locations including two rims and the front surface of the tire of the front wheel 200.

次に、この状態において、モータ115で雄ねじ1151を背板付ナット116との螺合が進む方向に回転すると、図3a3、b3、c3に示すように、雄ねじ1151と背板付ナット116との螺合が深まり、モータ115が前輪方向側端まで移動すると共に、背板付ナット116を介して連結軸1161を前輪200方向と逆方向に引き込むことにより、クランプ114の二つの爪1141を強く閉じて固定する。そして、この結果、前輪200が、二つの爪1141と背板付ナット116の背板部分によって前輪200のリムの左右二カ所と前輪200のタイヤ前面との計三カ所で強く握持され、固定装置12に対して固定される。   Next, in this state, when the motor 115 rotates the male screw 1151 in a direction in which the screwing with the back plate nut 116 proceeds, as shown in FIGS. 3a3, b3, and c3, the male screw 1151 and the back plate nut 116 are screwed together. The motor 115 moves to the front wheel direction side end, and the connecting shaft 1161 is pulled in the direction opposite to the front wheel 200 direction via the nut 116 with the back plate, so that the two claws 1141 of the clamp 114 are firmly closed and fixed. . As a result, the front wheel 200 is strongly held by the two claws 1141 and the back plate portion of the back plate nut 116 at a total of three locations, the left and right rims of the front wheel 200, and the front surface of the tire of the front wheel 200. 12 is fixed.

なお、この状態からの前輪200の固定の解除は、モータ115で雄ねじ1151を背板付ナット116との螺合が戻る方向に回転すると共に、これによって前輪200方向と逆方向に移動したモータ115を前輪方向側にスライドすればよい。
以上、本発明の実施形態について説明した。
以上のように本実施形態によれば、前輪200のリムの内周側の面の左右二カ所と前記前輪200のタイヤの外周側の面の一カ所との計三カ所を、二つの爪1141と背板付ナット116の背板部分とで挟持することにより、前輪200を握るようにして固定するので、自動二輪車の前後方向を含む各方向について、摩擦力のみによらない前輪200と爪1141や背板部分との掛合による拘束力をも用いた前輪200の固定が実現される。したがって、左右から前輪200を挟みつける板状部材と前輪200と間の摩擦力のみによって前輪200を固定する場合に比べ、より強固に自動二輪車の前輪200を固定することができる。また、前輪200の回転軸と等しい高さにおいて当該前輪200を固定するようにしているので、自動二輪車の前後方向の力に対して、より安定的に当該前輪200を固定することができるようになる。また、背板付ナット116の背板部分に前輪200を押し込むことにより二つの爪1141が閉じるように構成されているので、作業者は自動二輪車の前輪200を二つの爪1141の間に押し込むだけの簡単な作業で、前輪200を固定することができるようになる。
To release the fixed state of the front wheel 200 from this state, the motor 115 rotates the male screw 1151 in a direction in which the screwing with the nut 116 with the back plate returns, and the motor 115 moved in the direction opposite to the direction of the front wheel 200 is thereby moved. What is necessary is just to slide to the front wheel direction side.
The embodiment of the present invention has been described above.
As described above, according to the present embodiment, the two claws 1141 include a total of three locations, two on the left and right of the inner peripheral surface of the front wheel 200 and one on the outer peripheral surface of the tire of the front wheel 200. And the back plate portion of the nut 116 with the back plate, so that the front wheel 200 is gripped and fixed. Therefore, the front wheel 200 and the claw 1141 that do not depend only on the frictional force are included in each direction including the front and rear direction of the motorcycle. The front wheel 200 can be fixed using the restraining force by engaging with the back plate portion. Therefore, the front wheel 200 of the motorcycle can be fixed more firmly than in the case where the front wheel 200 is fixed only by the frictional force between the plate-like member that sandwiches the front wheel 200 from the left and right and the front wheel 200. Further, since the front wheel 200 is fixed at a height equal to the rotational axis of the front wheel 200, the front wheel 200 can be fixed more stably against the force in the front-rear direction of the motorcycle. Become. Further, since the two claws 1141 are closed by pushing the front wheel 200 into the back plate portion of the nut 116 with the back plate, the operator only pushes the front wheel 200 of the motorcycle between the two claws 1141. The front wheel 200 can be fixed with a simple operation.
