Braking performance tester calibrating device

The utility model discloses automobile detection equipment for the automobile industrial field and relates to a braking performance tester calibrating device. The braking performance tester calibrating device solves the problems that in the prior art, vibration is large, the measuring range is small, only static measurement can be conducted, dynamic measurement cannot be conducted, and the axis of a sensor cannot pass through the rotation center of a rotation platform. The braking performance tester calibrating device is mainly composed of a sensor adjustment part, an image collection part, a braking performance tester fixing part, a speed measurement part, a speed adjustment part, a control part and an outer supporting part. The sensor adjustment part is fixed on the right of the braking performance tester fixing part. The image collection part is fixed on the front side of the braking performance tester fixing part. The speed measurement part is fixed on the lower surface of an outer supporting part platform in the outer supporting part. The braking performance tester calibrating device has small vibration, stable transmission and a large measurement range and completely meets the test requirement for 0g-2 g. The braking performance tester calibrating device can be used for completing not only static measurement but also dynamic measurement.
