What does a radius arm do?
What does a radius arm do? A radius rod (also called a radius arm, torque arm, torque spring, and torsion bar) is a suspension link intended to control wheel motion in the longitudinal (fore-aft) direction. Radius rods in aircraft must be regularly inspected because their failure will cause unrestrained swerving of the wheel. Why is 4 link suspended? The benefits of a four-link over a simple leaf-spring suspension include controlling axlewrap, better departure angles, controlling axle path, and reducing the uncontrolled variables of axle movement down to just spring rate and shock valving. How is the position of the arm...
