Brake Drum: A Key Component of the Automotive Braking System
I. Structure and Location
The brake drum typically has a cylindrical shape and is installed on the rotating part of the wheel, generally being connected to the
Wheel Hub. It is crafted from robust materials such as cast iron, boasting high strength and excellent wear resistance.
II. Working Principle
Upon depressing the brake pedal, the braking system causes the brake shoes to expand outward via hydraulic or mechanical means, generating friction with the inner surface of the brake drum. This frictional force impedes the rotation of the wheel, thereby decelerating or bringing the vehicle to a halt.
III. Characteristics
Powerful braking force: The brake drum can supply substantial braking force, making it especially suitable for large vehicles or situations that demand significant braking power.
Low cost: Compared to other braking components, the manufacturing cost of the brake drum is relatively inexpensive.
Good stability: During prolonged use, the performance of the brake drum remains relatively stable, and it is not prone to sudden failures.
IV. Maintenance and Precautions
Regular inspection: It is essential to periodically check the wear condition of the brake drum. If excessive wear is detected, it should be replaced promptly.
Keep clean: Avoid allowing impurities to enter the brake drum to ensure the braking effect is not compromised.
Pay attention to temperature: When braking for an extended period or frequently braking, the brake drum will generate a relatively high temperature. Avoid contacting it with cold water immediately when it is in a high-temperature state to prevent deformation of the brake drum.
