As shown in the figure, the axle 3 into which both wheels 2a and 2b are press-fitted,
It is arranged between the left and right press cylinders 6a and 6b, and firstly, the wheel 2a on one end 3a side of the axle 3 and the one press cylinder 6a
A predetermined test load is applied to the surface of the other end 3b of the axle 3 by the other press cylinder 6b with the press load receiving metal 23a interposed therebetween. Then, the displacement of the rod 6 'of the press cylinder 6b at this time is detected. If the displacement is equal to or more than a predetermined value, it is determined that the interference of one of the wheels 2a is loose and a displacement (displacement) has occurred.

いた。As described above, in the conventional test operation, the wheels 2a and 2b press-fitted on both sides of the axle 3 are used.
, It was necessary to repeat the same pressure measurement operation twice, which required a considerable amount of time. Further, since the left and right end surfaces of the axle 3 are pressurizing surfaces of the press cylinders 6a and 6b, damage to the both end surfaces due to high surface pressure is likely to occur. In addition, when the end surface of the axle 3 is pressurized, the amount of shrinkage from the axle end of the axle 3 to the wheel boss surface also increases.

精度な検圧測定を行なうことができる。As described above, according to the pressure detecting device of the present invention, a pressure test load is simultaneously applied to the wheels press-fitted on both sides of the axle by one press cylinder on one side, and both wheels are pressed. The resulting displacement can be detected simultaneously. Therefore, it is not necessary to repeat the same inspection work twice for the wheels on both sides of the axle, and the operation time is greatly reduced. Also,
A load is not applied to the end surface of the axle and the structure presses the boss surfaces of both wheels, so an even load is applied and there is almost no adverse effect due to the shrinkage of the axle. A measurement can be made.

項１又は２に記載の車輪の検圧装置。3. A displacement generated on one of the wheels to which the test pressure load is applied via a wheel presser is detected by a detection value of a sensor for detecting a displacement of a rod of a press cylinder, and the test pressure load is detected by a wheel. The displacement generated on the other wheel added via the receiving metal is detected by a detection value of either a sensor for detecting the displacement of the axle or the sensor for detecting the displacement of the rod, and is simultaneously generated on both wheels. The displacement that occurred on the other wheel is detected by a detection value of a sensor that detects displacement of the axle, and the displacement that occurs on one wheel is detected by a detection value of a sensor that detects displacement of the rod. The wheel pressure detecting device according to claim 1, wherein the detection is performed as a difference from a detection value of a sensor that detects a displacement of the wheel.
