Electro-hydraulic Drum Brakes

Electro-hydraulic Drum BrakesThe principle of operation of drum brakes
In the drum brake friction force is due to the fact that under the action of the cam forces the brake pads located inside the inner surfaces are pressed against the brake drums. Thanks much private housing pads are well protected from the effects of corrosion (water, salt, dust) and dirt (sand, stones, mud), even when driving on hard terrain.
When using the brakes, S-shaped cam brake cylinder by adjusting the brake lever and the shaft rotates the S-shaped cam, thereby pressing the brake shoes with linings to the brake drum.
Adjusting levers
Automatic self-adjusting levers align the brake pads wear and drums, establishing between them a constant air gap.
Drum Brakes benefits

  1. Durability and reliability
  2. Suitability for heavy applications, even on dirt roads and in difficult environments
  3. Variety of options for different vehicles and applications
  4. Simple and priced maintenance and repairs

Electro-hydraulic drum brakes can be extensively used for various mechanism deceleration and stop/braking of various belt transport, port handling, hoisting, metallurgical, mining and building machinery.
Electro-hydraulic drum brakes work conditions:

  1. Ambient temperature:-25~+40℃.
  2. Relative humidity: ≤90%.
  3. Power: AC 3 phases 50(60)Hz.
  4. Voltages:380.400(440.460)V
  5. Operating duty: intermittent (S3-60%.1200/h) and continuous (S1).

Electro-hydraulic drum brakes work conditions features:

  1. Interlocking shoe clearance balancing device (patented technology) and shoe auto-aligning device constantly equalize the clearance of brake shoes on both sides and make adjustment unnecessary, completely avoiding brake lining one side sticking to brakes wheel.
  2. At main hinge points are equipped with self-lubricating bearings, which make higher efficiency of transmission and longer performance life, and lubricating is unnecessary during the course of operation.
  3. Brake spring is arranged inside square tube and surveyor's rod is placed on one side. It is easy for customers to read braking torque value and avoid the troubles of measuring and computing.
  4. Brake spring is arranged inside square tube and surveyor's rod is placed on one side. It is easy for customers to read braking torque value and avoid the troubles of measuring and computing.
  5. Brake lining is of card whole piece shaping structure, which is easy and quick to replace. Brake lining of various materials such as half-metal (non-asbestos) hard and half-hard, soft (include asbestos) substance are available for customer to choose.
  6. Electro-hydraulic Drum Brakes Advantages:
  7. Hand release lever.
  8. Open (Release) or close limit-switch, which indicates whether the brake is properly released or closed.
  9. Wear-self-compensation device, which realizes endless self-compensation of shoe clearance and torque when lining wears.
  10. Lining-wear limit-switch, equipped which signals will shown when wear of lining reaches the limit (note: self-compensation device should be equipped in application)
  11. Adopt thruster with fall delay valve as drive system which can realize closing delay of brake.
