DYNAPAC SHOCK ABSORBER

Introduction to Primary Suspension

The primary suspension in a railway bogie is the first stage of isolation between the wheel-rail interface and the vehicle body. It connects the axlebox (bearing housing) to the bogie frame, carrying the static vehicle weight while accommodating dynamic forces generated by track irregularities, curves, and braking events. Dynapac Shock Absorber supplies a comprehensive range of primary suspension rubber elements designed for the full spectrum of rolling stock applications.
