Brake pressure distribution measuring method and brake pressure distribution measuring device

摘要

PROBLEM TO BE SOLVED: To enable pressure distribution in the same state as an environment where a brake is actually actuated to be easily measured for each of both side surfaces of a rotor.SOLUTION: A brake pressure distribution measurement method comprises installing a displacement sensor 25 for an outer pad and a displacement sensor 26 for an inner pad between an outer disc plate 21 and inner disc plate 22 of a disc rotor 20, and measuring displacement of each pad slide surface. The method comprises executing analysis with a computer, based on minute displacement of each pad slide surface obtained by the measurement, and calculating pressure distribution on each pad slide surface. The method comprises forming a hole on the outer disc plate 21 and the inner disc plate 22 to locally reduce rigidity, or devising a structure of the displacement sensor to change sensitivity for each surface of each displacement sensor.SELECTED DRAWING: Figure 2
