For vehicle OEMs specialising in heavy-duty applications, the steering drag linkage and associated components are fundamental.
By transferring the driver’s steering input to the corresponding steering linkage, the steering drag link ensures precise directional control, even under the rigorous demands of challenging on-road or off-road environments.
A well-chosen and properly maintained steering drag link enhances handling stability, reduces downtime and supports compliance with stringent safety and performance standards demanded by defence, public transport and freight sectors.
In heavy commercial and military-grade steering systems, the drag link assembly converts rotational input from the steering gear into linear motion. This linear motion then influences the steering arm or tie rod assembly, which in turn adjusts the road wheel angles.
With greater vehicle mass, axle loads and more complex suspension designs, the steering drag link in these heavy-duty contexts must withstand substantial stress and maintain precise alignment.
Engineers must ensure that the drag link’s geometry, materials and tolerances complement the steering box output and integrate seamlessly with other components, guaranteeing consistent, predictable handling for large, complex vehicles.
When specifying steering drag link assemblies for heavy vehicles there are several critical factors.
