In automotive suspension, a control arm, also known as an A-arm, is a hinged suspension 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 with 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 prevent 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.
A control arm, commonly referred to as an A-arm, is a hinged suspension link used in automobile suspension that connects the chassis to the hub that supports the wheel. A control arm's inboard (chassis) end is connected to the body by a single pivot, which is typically a rubber bushing. Thus, it may maintain the radial separation from the inboard mount while controlling the position of the outboard end in just one degree of freedom. The arm can move back and forth even if it is not intended to do so; nevertheless, this motion is restricted by a different link or radius rod.
