The present invention relates to a lateral pressure measurement apparatus in a wheel plate, and is characterized by comprising; a plurality of strain gages for lateral pressure measurement installed on an outside face of a wheel plate; a gage bridge for lateral pressure measurement to change the deformation of a measurement subject sensed from the strain gage for lateral pressure measurement to a resistance change for conversion to a voltage change; an A/D converter to change deformation signals of the measurement subject from the gage bridge for lateral pressure measurement to digital signals; and a data processing means to convert the digital signals converted by the A/D converter to lateral pressure data. According to the present invention, sensitivity similar to that of the existing method of lateral pressure measurement with attachment of strain gages for lateral pressures measurement on both the outside and inside of the wheel plate may be obtained by attaching a strain gage for lateral pressure measurement only on the outside of the wheel plate to measure lateral pressure in the wheel plate. |
