Breif introduction:
The most capacities of bogie’s spring suspension gadget are: 1. When the train and vehicle passes through the uneven line or vibration and affect happen due to wheel set abandons, it can ease the affect and weaken the vibration; 2. Make the weight conveyance between the wheel sets of the same bogie fitting, so that the wheel stack of each wheel set will not shift as well much beneath different line conditions.
Springs for bogie’s suspension are made of high-strength spring steel by hot coil or cold coil, and fabricated agreeing to AAR, EN or Chinese railroad measures.
