2.5 SUSPENSIONS<br />
Suspensions in a bogie are provided to reduce the vibrations. The vibrations are picked<br />
up by the wheel which is mounted on railway track which itself is shaking up and down due to<br />
irregularities in the surface. The suspension system also balances the vertical loads between the<br />
wheels and provides passenger comfort by reducing vibrations in the vehicle body.<br />
The suspension between the axle and the bogie frame constitutes the primary suspension. The<br />
suspension between the bogie frame and the vehicle body is called secondary suspension.
