A trailing arm suspension is principally a rigid member which pivots about its attachment to the tractor frame. This arm extends rearwards and provides attachment for drive wheel axles as well as the lower end of suspension components. When torque is applied to the drive wheels, while the truck is at rest, there exist conditions under which the drive wheels oscillate more or less vertically, and build in amplitude until the wheels 'hop' off the road. As the truck accelerates forwards, this wheel hop ceases. This paper investigates this instability and exposes it in a fundamental way. A linearized analysis yields stability criteria, and a nonlinear simulation model demonstrate this instability.
