SYSTEM FOR MEASURING THE MOVEMENT OF A BRAKE DISC TO REDUCE THE SQUEAL NOISE OF THE BRAKE DISC

摘要

PURPOSE: A system for measuring the movement of a brake disc is provided to measure the axial movement and rotation of the brake disc and to effectively measure the movement of a rotator.;CONSTITUTION: A system for measuring the movement of a brake disc(150) comprises a wheel shaft(140), the brake disc, a brake caliper, a brake pad(105), a rotation angle sensor(130), a three-axis acceleration sensor(120), a reference acceleration sensor(110), and a signal processor(170). A wheel is mounted on one side of the wheel shaft. The brake disc is installed in one side of the wheel shaft to rotate with the wheel shaft. The brake caliper is arranged in both sides of the brake disc and is fixed on a vehicle body. The brake pad is fixed on the brake caliper to selectively contact to one side of the brake disc. The rotation angle sensor detects the rotation of the wheel shaft. The three-axis acceleration sensor is mounted on one side of the brake disc.;COPYRIGHT KIPO 2013
