Abstract
A device for suppressing brake noise wherein a rod is provided upright on the inside of the rim to which the brake lining is fitted, and a weight is fitted to this rod by way of an elastic body. By fitting a weight to the brake shoe by way of an intermediary elastic body, the weight will vibrate when it is subject to the vibration of the brake shoe. At low frequencies the vibration of the weight will be in phase with the vibration of the brake shoe, but as the vibration frequency of the brake shoe increases, the vibration of the weight will shift out of phase with the vibration of the brake shoe. In the vicinity of and above a certain frequency, this phase difference will become nearly 180 degrees. By matching this frequency to the brake noise frequency, the vibration of the brake shoe can be suppressed by the vibration of the weight.
