Brake performance tester calibrating device

The invention discloses automobile detection equipment in the field of automobile industry, relates to a brake performance tester calibrating device, and solves the problems that in the prior art, vibration is serious, the measuring range is small, only static measurement, rather than dynamic measurement, can be carried out, and the axis of a sensor cannot pass through a rotary center of a rotating platform. The brake performance tester calibrating device mainly comprises a sensor regulating part, an image acquisition part, a brake performance tester fixing part, a speed measuring part, a speed regulating part, a control part and an outer supporting part, wherein the sensor regulating part is fixed on the right side of the brake performance tester fixing part; the image acquisition part is fixed on the front side of the brake performance tester fixing part; the speed measuring part is fixed on the lower surface of an outer supporting part platform of the outer supporting part. The brake performance tester calibrating device is slight in vibration, stable in transmission, and large in measurement range and can completely meet a 0-2 g test requirement; the brake performance tester calibrating device can complete both static measurement and dynamic measurement on the same device.
