Rubber Torsion Axle Suspension

Rubber torsion axles start out as square stock tubes just like any other axles but that s where the similarity ends.

Rubber torsion axle suspension.

Home trailer parts accessories axle assemblies rubber torsion axles regarding torsion style axles we need to know if you have a single axle or multiple axle setup. The torflex axle provides improved suspension characteristics relative to leaf spring axles through the unique arrangement of a steel torsion bar surrounded by four rubber cords encased in the main structural member of the axle beam. As an alternative to the leaf spring systems the rubber suspension axles movement between bump and rebound compresses the rubber elements within thus providing a dampening of bumps on the road. The wheel hub spindle is attached to a lever called the torsion arm which is fastened to the rubber encased bar.

The torflex axle provides improved suspension characteristics relative to leaf spring axles through the unique arrangement of a steel torsion bar surrounded by four rubber cords encased in the main structural member of the axle beam. Four rubberized cords are inside the axle housing which handle suspension travel and shock absorption. If you are replacing a torsion axle in a multiple axle setup the replacement axle must be the same brand as the old one. The independent rubber suspension axle is a square hollow axle tube housing rubber elements held in place by an inner tube.

The unique self dampening characteristics of the rubber element slow down the suspension rebound as shown in figure 1 which ensures a smooth ride over all types of road surfaces. The other end of this short arm rides on a bearing. The skinny on torsion axles. As each wheel moves up and down the rubber cords compress offering an even wheel.

It attaches directly to the trailer chassis using brackets which are an integral part of the axle assembly. Torsion axles torsion axles use a twisting motion where the bar inside the axle tube rolls against rubber cords or a rubber wall to create compression and resistance. Torsion axles have a straightforward attached construction with adjustable ride height and a rubberized suspension system. The torflex suspension system is a torsion arm type suspension which is completely self contained within the axle tube.

On a normal axle the wheel would just slide onto a spindle and a bearing on the end of the tube with this configuration the wheel slides onto a stubby spindle protruding from one end of a lever arm aka the torsion arm.
