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 controlled?
It can thus control the position of the outboard end in only a single degree of freedom, maintaining the radial distance from the inboard mount. Although not deliberately free to move, the single bushing does not control the arm from moving back and forth; this motion is constrained by a separate link or radius rod.
How does a radius arm stop the axle from rotating?
The same rotational control can be obtained by using a second mounting point on the axle per link. Having two mounting points per link stops the axle from rotating by fixing the rotation to the path of the links. This type of system is known as a radius arm.
How is the control arm attached to the chassis?
The inboard (chassis) end of a control arm is attached by a single pivot, usually a rubber bushing. It can thus control the position of the outboard end in only a single degree of freedom, maintaining the radial distance from the inboard mount.
When does the custom radialcontroller tool is active?
Occurs while a custom RadialController tool (defined by an app) is active, and either the app associated with the RadialController object is sent to the background, or the user activates the RadialController menu. Occurs when the wheel device is rotated while a custom RadialController tool is active.
It can thus control the position of the outboard end in only a single degree of freedom, maintaining the radial distance from the inboard mount. Although not deliberately free to move, the single bushing does not control the arm from moving back and forth; this motion is constrained by a separate link or radius rod.
How does the radial nerve work in the upper arm?
In the upper arm the radial nerve wraps around the back side of the humerus bone. The nerve gives function to the triceps muscles on the back of the arm to straighten the elbow. Because the radial nerve wraps around the humerus bone, it can be stretched or torn when the humerus bone is broken.
