Railway Axle Box

Introduction Of Railway Axle Box

The axle box focuses on the stability of the terminal of power output. Its unique hydraulic damping system can absorb 80% of the wheel-rail impact vibration. The sealing structure adopts a multi-layer labyrinth design combined with magnetic fluid sealing technology, which increases the efficiency of isolating external contaminants to 99.97%. The temperature adaptive compensation mechanism can automatically adjust the axial clearance to the 0.05mm level, ensuring that the bearing system is always in the best working condition.

The axle box adopts a composite casting process of compacted graphite iron (CGI450) and aluminum alloy. The wall thickness of the box body has been designed through topology optimization, achieving a 30% weight reduction while ensuring structural strength. The copper-based graphite self-lubricating bushings embedded inside can maintain a stable coefficient of friction under operating conditions ranging from -40
℃ to 150℃.
