Method of measuring the wheel stiffness and wheel stiffness measurement device

摘要

PPROBLEM TO BE SOLVED: To provide a wheel rigidity measuring instrument and a wheel rigidity measuring method for easily measuring the rigidity of a wheel in all directions with respect to the wheel radial direction. PSOLUTION: This wheel rigidity measuring instrument includes a seat 14 for fixing the periphery of the wheel 4, a driving means 26 for rotating the seat 14, a load arm 18 fixed on a hub face of the wheel 4, a load generating means 19 for imposing a load on the wheel 4 by inclining the load arm 18, a target member 21 connected to the load arm 18 and/or the wheel 4 with its measurement surface 20 disposed thereon, a distance measuring means 22 for measuring a distance from the measurement surface 20 to the target member 21, and a rotation angle measuring means 23 for measuring a rotation angle of the wheel 4. The inclination of the measurement surface 20 is detected from the measuring means 22. While rotating the wheel 4, the rigidity of the wheel 4 is measured from the inclination of the measurement surface 20, the load of the generating means 19, and the rotation angle of the wheel 4.
