What Is Primary Suspension? Where Is It Used?
Primary suspension refers to the suspension components located between the axlebox and the bogie frame in rail vehicles. It is a critical system designed to isolate vibration and absorb shocks coming from the rail track. These components enhance ride comfort and protect other vehicle parts from mechanical stress.
Where Is Primary Suspension Used?
- ✓ Between axle and bogie in trains
- ✓ In metro, tram, and light rail vehicles
- ✓ In freight wagons
- ✓ In high-speed passenger trains
What Does Primary Suspension Do?
Primary suspension systems absorb track-induced shocks and reduce vibration transmission to the bogie. They help:
- ✓ Distribute dynamic loads evenly
- ✓ Reduce wheel and rail wear
- ✓ Enable better axle movement during curves
- ✓ Improve passenger comfort and safety
