“Better safe than sorry” – especially when driving “kings of the road” like trucks. One of the most crucial components requiring attention is the braking system, particularly drum brakes – the “silent heroes” ensuring safety on every journey. Let’s explore the detailed structure of drum brakes with Xe Tai Ha Noi, understanding their operating principles and maintenance methods to guarantee absolute safety for you and the community.

Detailed Analysis of Drum Brake Structure

To understand drum brakes, imagine watching a magic show with a mystical drum. When you apply the brakes, the “magic wand” – the hydraulic piston – acts on the “drum surface” – the brake shoes, creating friction. This friction helps the truck decelerate safely.

1. Main Components:

  • Drum: This is the stationary part, shaped like a drum, usually made of cast iron or steel.
  • Brake Shoes: Mounted inside the drum, brake shoes are made of high-friction, heat-resistant material. When you brake, the shoes rub against the drum to slow the vehicle.
  • Hydraulic Piston: Like a “bridge,” the hydraulic piston transmits force from the brake pedal to the brake shoes, making them contact the drum.
  • Return Springs: The “balance keepers,” return springs bring the brake shoes back to their original position after you release the brakes.
  • Adjuster Assembly: This component adjusts the distance between the brake shoes and the drum, ensuring optimal braking performance.

2. Operating Principle:

  • When you press the brake pedal, brake fluid is pushed to the hydraulic piston.
  • The hydraulic piston pushes the brake shoes against the drum, creating friction.
  • This friction converts kinetic energy into heat, slowing the truck down.
  • When you release the brake pedal, the return springs retract the brake shoes, ending the braking process.
