What does a band brake mean?
1 Answers
It utilizes friction to reduce rotational speed, achieving the purpose of deceleration and stopping. More extended information is as follows:1. Band Brake: The principle of a band brake is basically the same as that of an expanding brake, but structurally, the brake lining is on the outside while the hub is on the inside. When the brake pedal is pressed, the brake lining clamps inward to embrace the hub.2. Expanding Brake: Mainly composed of brake linings and a brake hub, the brake hub is a circular, hollow metal disc, resembling the shape of a cooking pot lid, with its center point connected to the wheel or axle; inside the hub, there are two semi-circular brake linings that meet. Since the brake linings are semi-circular, the two pointed ends of each lining correspond to each other. One end of the meeting point is a cylindrical shaft, and the other end is an oval shaft. When the brake is pressed, the oval shaft rotates, causing the semi-circular brake linings to separate outward, and the outer side of the linings rubs against the hub, creating resistance to reduce speed.
