Category Overview
The Mechanical Link Between Bogie and Vehicle Body
Railway traction rod assemblies serve as the vital mechanical link transmitting braking and traction forces between the bogie and the vehicle body. We source and supply a wide array of high-strength bogie traction rods, center traction rods, steering rods, and gearbox boom compositions fitted with pre-compressed elastic rubber bushes, and arrange non-standard production to your drawings when a catalogue part does not fit.
Designed to accommodate multi-axis bogie movements while maintaining longitudinal rigidity, traction link compositions with elastic bushes help isolate impact loads and operational noise. Typical construction uses seamless precision steel tubing and drop-forged rod ends, specified per drawing for the long service-interval demands of passenger cars and locomotives.
-
Traction Force Transfer
Carries longitudinal traction force from the bogie to the carbody.
-
Braking Force Path
Returns braking force through the same rod and bush interface.
-
Movement and Noise Isolation
Elastic bushes allow multi-axis movement and help isolate impact loads and noise.

Engineering Details That Matter in Service
Typical construction options for traction rod assemblies. Final material grade, coating system and test requirements are confirmed against your drawing at quotation.
Seamless Welded Tube
Rod bodies made from seamless precision steel tube with welded end fittings, cut to the installation centre distance on your drawing.
Drop-Forged Rod Body and Ends
Drop-forged rods and eye ends for solid-bar designs, giving a continuous grain flow through the load path.
Anti-Corrosion Surface Treatment
Zinc-aluminium coating or electrophoretic paint options to protect rod bodies against corrosion in service.
Pre-Compressed Elastic Rubber Bushes
Bushes are pressed into the rod ends to allow multi-axis bogie movement while keeping longitudinal rigidity.
