Train Bogie Secondary Suspension Rail Transport Rubber Side & Center-bearing

Product Features and Applications:

In the bogie secondary suspension, it bears vertical loads and provides lateral or rotational elastic recovery force when the vehicle passes through curves; when used in the central traction part, it mainly bears traction and braking forces. The side-bearing rubber pile can absorb high-frequency vibration and has a significant effect in blocking noise.

Main Features:

1. Constructed using multi-layer steel plates and rubber, bonded together through vulcanization, featuring a simple structure.
2. Ensures accurate installation positioning by maintaining the relative positions of metal pins.
3. Exhibits minimal vertical deflection, suitable for bearing heavy loads; no instability and zero point drift meet requirements.
4. Exhibits minimal shear stress relaxation and good lateral elastic recovery, beneficial for vehicles' curve snake-like movement requirements.
5. Product features convenient work height adjustment.
6. Under vertical loads, it demonstrates excellent repetitive shear deformation capability, meeting the operational characteristics required for wear resistance and maintenance-free operation.
7. Exposed metal plate surfaces are painted for corrosion protection, with colors matching the bogie.
