て、複数点での厚さを平均する等して測定している。The clutch disc is made of a friction material whose friction fading has a large variation in dimensional accuracy, and the cushion plate sandwiched by this friction fading is a corrugated spring material with a large variation in dimensional accuracy. The thickness, the compression thickness when the clutch is compressed by the flywheel and the pressure plate,
There is variation in the parallelism of the two friction fadings. Such a clutch disc will not operate normally if the variation in external dimensions exceeds the allowable range.Therefore, when the clutch disc is used alone, the free thickness, compression thickness, and parallelism can be measured with a dial gauge or a micrometer. The needles are applied to a plurality of points at equal intervals on the periphery of the clutch disk, and the thicknesses at the plurality of points are averaged for measurement.

The clutch disc (1) at this time corresponds to the state of the clutch disc when incorporated in the clutch mechanism of the automobile, and the free thickness D 1 of the clutch disc (1) at this time is determined by the three disc thickness measuring means (8).
To measure. That is, when the clutch disc (1) is lightly contacted with the upper pressing body (3) by the lower pressing body (2), the measuring needles (19) of the three disc thickness measuring means (8).
... is pushed up by the peripheral portion of the upper surface of the lower pressing body (2),
The distance between each of the lower pressing body (2) and the upper pressing body (3) is measured at three points of 120 ° around the periphery. The average of the measured values at these three points is the free thickness D 1 of the clutch disc (1).
And the parallelism due to the warp of the clutch disc (1) is detected by the difference between the measured values at the three points. Such measurement is performed with high accuracy for the following reasons.

の測定値の差から正確な平行度が測定される。That is, when the clutch disc (1) is swung back and forth, left and right, and pressed against the upper pressing body (3) of the head portion (5) whose apparent weight is set to zero, the clutch disc (1) The head portion (5) swings so as to correspond to the variation in the thickness, and comes into contact with the clutch disc (1). For example, when the clutch disc (1) is warped as shown in FIG. 4 and the thickness varies, when the clutch disc (1) is pressed against the upper pressing body (3), the clutch disc ( Under the load of 1), the portion hitting the thicker portion is pushed up more strongly, the head portion (5) swings around the point P by this load, and the upper pressing body (3) has a warped clutch disc (3). Following 1), they are contacted with an average contact pressure. Therefore, at this time, if the distance between the upper and lower pressing bodies (2) and (3) is measured, the average accurate thickness of the clutch disk (1) can be measured, and the accurate difference can be obtained from the difference between a plurality of measured values. The parallelism is measured.

回転するので、圧縮厚、平行度の測定が正確になる。Next, the compression thickness measurement will be described. When the free thickness measurement is completed as described above, the lower pressing body (2) is further raised,
The upper pressing body (3) is pushed up while compressing the clutch disc (1), and the spacer (16) integrated with the upper pressing body (3) is pressed against the rocking body (4). From this time, the lower pressing body (2) is further raised, and the time when the clutch disc (1) is compressed by the same load as when the clutch is turned on during actual use is detected by the load checking means (13), and the lower pressing is performed. Stop the rise of body (2). This is the state shown in FIG. 5, and at this time, the intervals between the peripheral portions of the upper and lower pressing bodies (2) and (3) are measured by three disk thickness measuring means (8), and the average value is obtained. , Clutch disc (1) compression thickness
D 2 is measured, and the parallelism at the time of compression is measured from the difference between the measured values. Also in this case, since the head portion (5) swings and rotates according to the variation in the thickness of the compressed clutch disc (1), the compression thickness and parallelism can be measured accurately.

する。According to the present invention, when the clutch disk is brought into contact with the upper pressing body of the head section by the raising of the lower pressing body, the head section is rotatably held by the head supporting body and apparently by the head lifting means. Since the weight is set to zero,
When the clutch disc is pressed, the head part oscillates and rotates according to the variation in the thickness of the clutch disc, and comes into contact with the clutch disc following the clutch disc. When measured by the measuring means, it becomes possible to more accurately measure the free thickness of the clutch disk, the compression thickness, and the parallelism between free and compressed by averaging a plurality of measured values. Also, since these measurements are performed in the same state as when the clutch disc is actually used, there is a concern that it may cause troubles such as later clutch disengagement even if a good product of the measurement result is incorporated into the clutch mechanism of the automobile. It almost disappears, and the reliability of measured values is further improved.
