SUPPORTING MECHANISM OF AXLE SIX-COMPONENT FORCE METER ANGLE DETECTOR

PROBLEM TO BE SOLVED: To hold a standard coordinate system between an angle detector assembled in a slip ring and a vehicle body, and to improve accuracy by eliminating an error to angle change due to steering.SOLUTION: A six-component force meter 7 is disposed between a wheel hub 4 and a wheel 6 through a hub adapter 5, and receives external force applied from an axle to output signals corresponding to component force in X, Y, and Z axes directions and the moment about each axis. A supporting mechanism 9 of a slip ring is composed of first and second parallelogram links 10, 12 moving in parallel with an the X-axis direction, first and second rotation joints 11, 13 capable of moving the first and second parallelogram links 10, 12 in the Y-axis direction, and a third rotation joint 14 enabling relative rotations about the Z-axis between the second rotation joint 13 and the slip ring 8.
