Abstract
PURPOSE: To prevent a squeaky noise from being made by self-sustained oscillation, by cutting the peripheral surface of at least end part of each brake shoe near a cam to provide an opening between the brake shoe and the inside surface of a brake drum.
CONSTITUTION: Normally, there are openings 7, 8 aon both the ends 4a, 4b of a brake shoe 4 and clearances 7, 8 on both the ends 5a, 5b of another brake shoe 5. When a brake cam 2 is swung the front ends 4a, 5a of the shoes 4, 5 are pushed open and brought into pressure contact with the inside surface of a drum 1. At that time, because the clearances 7 are not all eliminated, not only the ends 4a, 5a first act intensely on the drum 1 to cause self-sustained oscillation. For that reason, a squeaky noise is prevented.
