The output shafts 4 and 5 are automatically connected to the output shaft 1b, and the shift 11 is also automatically connected. When the DC motor 3 is rotated in this state, the input side of the transmission 1 rotates via the input shaft 2 and the clutch portion 12, and the output side of the transmission 1 rotates via the transmission mechanism. This rotation is transmitted to the connecting shaft 6 via the output shafts 4, 5 and the belts 7, 8, and the DC motor 9 also rotates to absorb power. When shifting, the clutch unit 12 is disengaged, and the transmission 11 is shifted by the shift 11.
The transmission mechanism is operated to reconnect the clutch portion 12.

5 to 7 are a plan view, a front view, and an enlarged semi-longitudinal plan view of an input side portion of a conventional transmission test apparatus, and 13 is a clutch disc, which is attached to the input shaft 2. Has been. Reference numeral 14 denotes an inner clutch cover integrated with the clutch disc 13, which has a pressure contact plate inside. Numeral 15 is a clutch drive unit composed of a cylinder mechanism, and one end of a release lever 16 is freely connected to the tip of a ball pin 15b which is a piston protruding from the cylinder 15a. 17 is the spline shaft 1
8 is a first bearing that rotatably supports the thrust bearing portion 1 provided at the center of the release lever 16.
6a is also movably supported by the cylindrical thrust guide 17a of the bearing 17. The tip of the spline shaft 18 is splined to the pressure contact plate (driven side) of the clutch portion 12. The other end of the release lever 16 is engaged with the head of a bolt 20 screwed to a bearing support 19 that supports the bearing 17 via a nut 30. 21 is the clutch unit 1
An outer cover 2 and a spur gear 22 are fitted to the spline shaft 18, and are for detecting rotation by a pulse pickup.

It is a connection drive unit composed of a mechanism.

Next, in the configuration shown in FIGS. 5 to 7, when the ball pin 15b is moved to the left by the driving of the clutch drive unit 15, the release lever 16 rotates counterclockwise about the engaging portion with the bolt 20. Then, the press-contact plate in the clutch inner cover 14 is press-contacted to the clutch disc 13,
Is connected. On the contrary, when the ball pin 15b is moved to the right, the release lever 16 rotates clockwise, the pressure contact of the pressure contact plate is released, and the clutch portion 12 is disengaged.
Further, when the connection driving unit 29 is driven to move the slide arm 23 to the left along the rail 24b, the bearing 27 also moves to the left,
The automatic connecting portion 28 also moves to the left and is automatically connected to the input side of the transmission 1. If the slide arm 23 is moved to the right, the transmission 1
The connection with is released.

By the way, when the transmission 1 is repeatedly tested, the clutch disc 13 and the pressure contact plate are worn, so that it is necessary to shift gears. This exchange procedure will be described. First, the length A of the ball pin 15b from the tip of the cylinder 15a of the clutch drive unit 15 to the connecting portion with the release lever 16 is A.
Then, the length B of the bolt 20 from the reference surface 19a of the bearing support 19 to the root is measured and recorded. Next, the bolt 15b
And the clutch outer cover 21 having a split structure is also removed. Next, the stopper 26 is removed, and the LM guide 24

Next, a new pressure plate and clutch disc 13 are set, assembled in the reverse order of the above, and finally A,
Set to B size.

[0009]

In the above-mentioned conventional apparatus, since the spline shaft 18 needs to be taken out in the direction of arrow C when the clutch disc 13 or the like is exchanged, the slide arm 23 or the like is taken out before that. It is necessary, in addition to the stopper 26, the block 2 of the LM guide 24
4a and the rail 24b also had to be removed, which required time and labor for removal and installation, and also required time for centering the slide arm 23 and the LM guide 24. Also, the LM guide 24 is attached to the support base 25,
The slide arm 23 needs to be centered with the LM guide 24 as described above, while the bearing 17 is attached to the bearing support 19 and the spline shaft 18 has to be centered with respect to this bearing 17. Moreover, it is necessary to perform centering between the spline shaft 18 and the automatic connecting portion 28, and it is necessary to set the center runout allowable value to ± 0.03 mm or less. It was very difficult. Further, in the release lever 16, it is necessary to adjust the length of the bolt 20, and it is necessary to measure and adjust the A and B dimensions at the time of attachment and detachment.

The present invention has been made in order to solve the above-mentioned problems, and it is easy to attach and detach the components when the clutch portion is replaced, and it is easy to perform centering and adjustment between the components. The purpose is to obtain a transmission test device.
