Description

Large metal helical compression springs for railroads are designed to dampen shocks, absorb vibrations, control mechanism movements, store energy, and measure force. With exceptional elastic deformation capacity, these springs effectively absorb and moderate rail impact, protecting railroad equipment and enhancing ride comfort for passengers.

Main Features and Functions

  1. Shock and vibration absorption: Converts kinetic energy from rail impact into spring potential energy, improving comfort and safety.
  2. Suspension system integration: Widely used in railroad vehicle suspension to ensure stable and reliable operation over long periods.
  3. Fatigue life and reliability: Engineered for extended service life and consistent performance, with critical factors including spring structure, surface quality, stress management, and shot peening of end seams.

Spring Types

  1. Cylindrical helical compression springs: Simple structure, easy to manufacture; widely used in various applications.
  2. Rectangular cross-section cylindrical springs: Higher load capacity; ideal for energy absorption applications.
  3. Flat cross-section cylindrical springs: Efficient for specific mounting and load requirements.
  4. Unequal pitch cylindrical springs: Variable self-resonance frequency; excellent for high-speed variable load mechanisms, reducing resonance effects.
  5. Multi-stranded cylindrical springs: Enhanced reliability and adaptability to complex load scenarios.

Material Selection

  1. 55Si2Mn steel: High strength and elastic limit; ideal for flat springs and spiral springs <25mm in diameter subjected to medium loads.
  2. 60Si2MnA steel: Higher strength and elastic limit; suitable for plate springs with large loads and spiral springs ≤30mm in diameter.

Applications

  1. Railroad suspension systems: Ensures passenger comfort and equipment protection.
  2. Shock absorption and vibration control: Critical for safety and the longevity of railroad vehicles.
  3. High-speed and variable load mechanisms: Specialized spring types for advanced railroad technology and design.
