It is attached to the mounting base 4. A transaxle specimen is used as the specimen 5, and the torque meter 3 is connected to an input shaft of the transaxle. Reference numerals 7 and 8 denote two output shafts of the specimen 5, which are connected to oscillating transmissions 11 and 12 via torque meters 9 and 10, respectively, and the output shafts of the oscillating transmissions 11 and 12 are connected. Interconnected by a shaft 13,
It is connected via a flywheel 14 to a power absorber 15 such as a DC dynamometer.

In the above-described configuration, the specimen 5 is driven by the driving body 1 via the transmission 2 and the torque meter 3, and the two output shafts 7, 8 of the specimen 5 are connected to the torque meters 9, 10, respectively. The output sides of the oscillating transmissions 11 and 12 are connected by a connecting shaft 13 so as to rotate in the same direction as each other, and this output is transmitted via a flywheel 14.

[0005]

FIGS. 6 (a) and 6 (b) show a plan view and a side view of the specimen 5, in which the output shafts 7 and 8 are at the same position, and the input shaft and the output shafts 7 and 8 are shown. Assuming that the horizontal distance of the specimen 5 is A and the vertical distance is B, the dimensions A and B differ depending on the type and model number of the specimen 5. For this reason, if the position of the input shaft 17 is fixed, the positions of the output shafts 7 and 8 will be different. Therefore, conventionally, the rocking type transmissions 11 and 12 are used,
Alternatively, the speed-increasing gears 19 and 20 are of the swing type. However, if two rocking types are used, the structure becomes complicated,
The adjustment operation was complicated and large and expensive.

The present invention has been made to solve the above-described problems, and has as its object to provide a power train test apparatus that can be easily adjusted and that is relatively small and inexpensive.

[0007]

A power train test apparatus according to the present invention connects a drive unit to one input shaft of a power train via an oscillating transmission and simultaneously outputs two outputs of the power train. A power absorber is connected to a shaft via a fixed transmission.

[0008]

In the present invention, a drive unit is connected to one input shaft of the power train via a swing transmission, and two output shafts of the power train are connected via a fixed transmission. A power absorber is connected, and when the positional relationship between the input shaft and the output shaft of the power train changes depending on the model or the like, the oscillating transmission is oscillated and adjusted.

[0009]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view showing a configuration of a power train test apparatus according to this embodiment. An input shaft 17 of a transaxle specimen 5 is connected to a driving body 1 via an oscillating transmission 25 and a torque meter 3. Is done. The specimen 5 is attached to the specimen mounting base 4 via the face plate 26. The input sides of fixed transmissions 27 and 28 are connected to output shafts 7 and 8 of specimen 5 via torque meters 9 and 10, and the output sides of fixed transmissions 27 and 28 are mutually connected by connection shaft 13. And is connected to a power absorber 15 via a flywheel 14.

[0010] In the above configuration, the specimen 5 is driven by the driving body 1 via the oscillating transmission 25 and the torque meter 3.
And its output is transmitted from the output shafts 7 and 8 to the fixed transmissions 27 and 28 via the torque meters 9 and 10,
Outputs of the fixed transmissions 27 and 28 are absorbed by the power absorber 15 via the flywheel 14.

2 (a) and 2 (b) are a plan view and a front view of the oscillating transmission 25, wherein 29 is a mount, 30 is a support provided on the mount 29, and 31 is one end. An arm rotatably supported by the support unit 30, and an input shaft 32 connected to the driver 1 is provided at the center of rotation of the arm 31 of the support unit 30.
Is provided. Reference numeral 33 denotes an output shaft provided at the other end of the arm 31, and reference numeral 34 denotes a mounting portion provided on the mounting base 29, which has an elongated hole 34a. Reference numeral 35 denotes a pedestal for the arm 31, which is movably attached to the elongated hole 34a via a pin 36. Reference numeral 37 denotes a refueling unit similarly provided on the mounting base 29.

In the oscillating transmission 25 having the above structure,
When the dimensions of the specimen 5 are different and the positions of the output shafts 7 and 8 are fixed and the position of the input shaft 17 is moved, the pedestal 35 is moved accordingly to rotate the arm 31 and the output shaft 33.
Can be moved to match the position of the input shaft 17. The position of the input shaft 32 is not moved. Further, the torque arm 3 and the specimen mounting base 4 are also rotated together with the arm 31. Therefore, if the face plate 26 is also rotated, the mounting of the specimen 5 becomes defective. Therefore, as shown in FIG. 3, the mounting holes 26 of the face plate 26 to the test specimen mounting base 4 are formed.
a is a long hole, and the face plate 26 is not rotated.

As described above, according to the first embodiment, when the positional relationship between the input shaft 17 of the specimen 5 and the output shafts 7 and 8 changes, one oscillating transmission 25 is oscillated. The adjustment work can be facilitated. Also, fixed transmissions 27, 2
Since the structure 8 is simple, the size and cost can be reduced, and the flexibility of the system can be increased because there are few structural restrictions.

[0014]

As described above, according to the present invention, when the positional relationship between the input shaft and the output shaft of the power train changes, one rocking type transmission connected to the input shaft is rocked. By doing so, this can be adjusted, and adjustment is facilitated. In addition, the fixed type transmission has a simple structure, has few restrictions, is small and inexpensive, and can increase system flexibility.
