1. Background introduction of stepless adjustment double spring isolator

Problems with ordinary steel springs:

After installation, the civil error isolator is placed under the track, making maintenance difficult; At high speeds, the longitudinal and transverse stability is poor; The transition section between the vibration reducing track and the ordinary track has severe rail corrugation.

The advantages of infinitely adjustable double spring isolators:

Increased installation accuracy and good smoothness; Added threads for easy removal and easy maintenance; High lateral stiffness and good stability; The transition section is less prone to wave abrasion due to its small dynamic displacement.

2. Composition of stepless adjustment double spring isolator

The stepless adjustment double spring isolator consists of inner spring, outer spring, outer sleeve, adapter sleeve, stop block, base, connecting rod, upper top plate, rubber sealing ring, damping agent, and other parts.
