以下、この発明を実施するための最良の形態を図面とともに説明する。図１はこの発明の実施最良形態によるトランスアクスルの試験装置の平面図である。取付架台２に取り付けられたトランスアクスル１の入力軸には入力軸用トルクメータ３を介して駆動モータ４を連結するとともに、トランスアクスル１の一対の出力軸には角度のない（入力軸及び出力軸と平行な）アクスル軸５，６を介して出力軸用トルクメータ７，８を連結し、一方の出力軸用トルクメータ７には一方のダイナモメータ（動力吸収部）９を連結し、他方の出力軸用トルクメータ８には他方の位置固定のダイナモメータ（動力吸収部）１０を等速ボールジョイント１３を介して連結する。１４はレール１５上に入力軸と直角方向に移動可能に設けられた第１の移動台であり、第１の移動台１４上には一方の出力軸用トルクメータ７及びダイナモメータ９が取り付けられる。又、他方の出力軸用トルクメータ８はレール１６上に入力軸と直角方向に移動可能に設けられた第２の移動台１７上に取り付けられる。   The best mode for carrying out the present invention will be described below with reference to the drawings. FIG. 1 is a plan view of a transaxle testing apparatus according to the best mode of the present invention. A drive motor 4 is connected to the input shaft of the transaxle 1 attached to the mounting base 2 via an input shaft torque meter 3, and the pair of output shafts of the transaxle 1 have no angle (input shaft and output shaft). Output shaft torque meters 7 and 8 are connected through axle shafts 5 and 6 (parallel to the shaft), and one dynamometer (power absorbing portion) 9 is connected to one output shaft torque meter 7 and the other. The output shaft torque meter 8 is connected to the other position fixed dynamometer (power absorbing portion) 10 via a constant velocity ball joint 13. Reference numeral 14 denotes a first moving table provided on the rail 15 so as to be movable in a direction perpendicular to the input shaft. One output shaft torque meter 7 and a dynamometer 9 are mounted on the first moving table 14. . The other output shaft torque meter 8 is mounted on a second moving table 17 provided on the rail 16 so as to be movable in a direction perpendicular to the input shaft.

上記構成において、駆動モータ４を回転させると、トルクメータ３を介してトランスアクスル１の入力側及び出力側が駆動され、この駆動はアクセル軸５、６及びトルクメータ７，８、さらには等速ボールジョイント１３を介してダイナモメータ９，１０に伝えられ、動力が吸収される。ここで、トランスアクスル１の機種が異なり、その入力軸と出力軸の間隔Ａが異なった場合、トランスアクスル１の出力軸の位置が異なり、この出力軸と平行なアクスル軸５，６の位置も異なってくる。この場合、一方の出力側では第１の移動台１４をレール１５に沿って入力軸と直角方向に移動させ、トルクメータ７及びダイナモメータ９の回転軸の位置をアクスル軸５に合わせ、連結する。又、他方の出力側では第２の移動台１７をレール１６に沿って入力軸と直角方向に移動させ、トルクメータ８の回転軸の位置をアクセル軸６と合わせ、連結する。ダイナモメータ１０は位置固定であるが、等速ボールジョイント１３がトルクメータ８及びダイナモメータ１０と自在に連結されているので、トルクメータ８の回転軸の位置が軸方向に変化しても何ら支障はない。   In the above configuration, when the drive motor 4 is rotated, the input side and the output side of the transaxle 1 are driven via the torque meter 3, which is driven by the accelerator shafts 5 and 6, the torque meters 7 and 8, and the constant velocity ball. It is transmitted to the dynamometers 9 and 10 through the joint 13 and power is absorbed. Here, when the transaxle 1 is of a different model and the distance A between the input shaft and the output shaft is different, the position of the output shaft of the transaxle 1 is different, and the positions of the axle shafts 5 and 6 parallel to the output shaft are also different.

On the other output side, the second moving table 17 is moved along the rail 16 in a direction perpendicular to the input shaft, and the position of the rotating shaft of the torque meter 8 is aligned with the accelerator shaft 6 and connected. Although the position of the dynamometer 10 is fixed, the constant velocity ball joint 13 is freely connected to the torque meter 8 and the dynamometer 10, so that no problem occurs even if the rotational axis position of the torque meter 8 changes in the axial direction. There is no.

上記した実施最良形態においては、試験をするトランスアクスル１の入力軸と出力軸の間隔Ａが異なっても、第１及び第２の移動台１４，１７を入力軸と直角方向に移動させることにより、対応することができる。又、アクスル軸５，６はトランスアクスル１の入力軸及び出力軸と平行で角度を持たないので、長時間の走行試験を行っても支障が生じず、寿命を長くすることができる。   In the above-described best embodiment, even if the distance A between the input shaft and the output shaft of the transaxle 1 to be tested is different, the first and second moving platforms 14 and 17 are moved in the direction perpendicular to the input shaft. Can respond. Further, since the axle shafts 5 and 6 are parallel to the input shaft and the output shaft of the transaxle 1 and have no angle, no trouble occurs even if a long-time running test is performed, and the life can be extended.

なお、上記実施最良形態においては、一方の出力側ではトルクメータ７及びダイナモメータ９を第１の移動台１４上に取り付け、他方の出力側ではトルクメータ８を第２の移動台１７上に取り付け、トルクメータ８と位置固定のダイナモメータ１０とを等速ボールジョイント１３により連結したが、両方の出力側でトルクメータ７，８及びダイナモメータ９，１０をそれぞれ第１の移動台１４上に取り付けても良く、また両方の出力側でトルクメータ７，８をそれぞれ第２の移動台１７上に取り付け、このトルクメータ７，８と位置固定のダイナモメータ９，１０とを等速ボールジョイント１３により連結するようにしても良い。何れの場合も、上記した実施最良形態と同様の効果を奏する。   In the above embodiment, the torque meter 7 and the dynamometer 9 are mounted on the first moving base 14 on one output side, and the torque meter 8 is mounted on the second moving base 17 on the other output side. The torque meter 8 and the fixed dynamometer 10 are connected by a constant velocity ball joint 13, but the torque meters 7 and 8 and the dynamometers 9 and 10 are respectively mounted on the first moving table 14 on both output sides. The torque meters 7 and 8 may be mounted on the second moving table 17 on both output sides, and the torque meters 7 and 8 and the fixed dynamometers 9 and 10 may be connected by a constant velocity ball joint 13. You may make it connect. In either case, the same effect as the above-described best embodiment can be obtained.
