FASTWIN POWER CONTRAL ARM KNOWLEDGE:
In automative suspension, a control arm, also known as an A-arm, is a hinged susppension link between the chassis and the suspension upright or hub that carries the wheel.
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. 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.
This is in contrast to the wishbone. Wishbones are triangular and have two widely spaced inboard bearings. These constrain the outboard end of the wishbone from moving back and forth, controlling two degrees of freedom, and without requiring additional links.
Most control arms form the lower link of a suspension. A few designs use them as the upper link, usually with a lower wishbone. The additional radius rod is then attached to the upper arm.
The Anatomy of Control Arms
Most vehicles such as SUVs, trucks, and other four-wheel-drive vehicles will contain both upper and lower control arms, while other front-wheel drive vehicles may only have a lower control arm with a strut in place of an upper control arm.
The control arms are located in the front wheels, with the upper control arms attaching to the uppermost part and the lower control arms connecting to the bottom part of the wheel. Both control arms connect to the car’s front frame through 2 bushings which allow the arm to move up and down and absorb noise, vibration by preventing the metal to metal contact.
