What Axle Systems are Typical?
A. Straight Axle – This is a common trailer type axle which has a fixed member connecting both wheel spindles. Connection to the trailer frame is usually via leaf springs on two points per side. Advantages include more even distribution of the load on the trailer frame and simple parts and repairs. B. Torsion Axle – This is the other common axle type used. Each wheel spindle is connected to its own torsion bar/axle assembly. This axle type enables fully independent suspension with very little space requirement in a very simple design. Since the load is not as evenly distributed, this axle design requires a little more attention for frame support. The advantages include smoother riding of the trailer and contents.
