RUBBER TORSION SUSPENSION

Rubber Torsion axles are available in a range of styles including straight, V shape and 2 piece (Stub axle) styles, with various hub & brake systems giving capacities of 750 kg – 3000kg per axle.

Rubber Torsion axles are a torsion arm type suspension which is completely self-contained within the axle tube. It attaches directly to the trailer chassis using brackets which are an integral part of the axle assembly.  Torsion axles provide improved suspension characteristics when compared to leaf spring axles due to the unique arrangement of a steel bar surrounded by four rubber cords encased in the main structural member of the axle beam. The wheel/hub stubs are attached to a lever, called a torsion arm, which is fastened to the rubber encased bar. As load is applied, the bar rotates causing a rolling/compressive resistance in the rubber cords. This system provides true independent suspension, with far fewer components than conventional systems.

Due to the way these axles are designed and manufactured, the ride height can be set at various positions during production to suit a raised or lowered height, they are self-damping and independent.  Rubber Torsion axles, deliver a smooth, quiet ride resulting in an improved towing experience.

Apart from periodic inspection of the fasteners used to attach the axle to the vehicle frame, no other suspension maintenance is required on Rubber Torsion Suspensions.  They are, of course, subject to normal maintenance and inspection procedures regarding brakes, hubs, bearings, seals, wheels and tyres.

The inbuilt strength of the torsion axle means that it can be used as a structural cross member which reduces chassis weight. Further, depending on the configuration, torsion axles can save weight when compared to the total weight of a traditional system.  This is largely due to the fact that rubber torsion axles are an axle and suspension in one unit, rather than a combination of axle and suspension.
