A floor-standing brake master cylinder performance test device and method

Abstract

A floor-standing brake master cylinder performance test device, including an air source system, a fixed base, an adjustable support and a pressure rod mechanism, the adjustable support is arranged on the fixed base, and the adjustable support is equipped with a brake master cylinder. The pressure rod mechanism can be rotatably installed on the top surface of the fixed base. The center of its rotating shaft overlaps with the center of the pedal rotating shaft of the master cylinder. The suspender is installed with a roller against the pedal force sensor, the central axis of the bracket suspender is perpendicular to the upper surface of the pedal force sensor, a displacement sensor is fixed on the side of the adjustable support, and the displacement sensor is connected with the end of the pedal by a stay wire. The invention also discloses a floor type brake master cylinder performance test method, through the displacement sensor test and calculation, can accurately calculate and obtain the pedal angular travel amount, which is not directly related to the starting point of the displacement sensor pull wire, and has strong applicability.
