Chrysler Sebring Rear Control Arm
About Rear Control Arm
Conversely, the control arm of an automobile is also identified as the A-arm, essentially it is a hinged suspension link between the chassis and the suspension upright/hub carrying the wheel. A base (inboard) of a control arm is directly linked via a single pivot that is generally a rubber bushing. This empowers it to handle the position of the outboard end in a single degree of freedom, while trying to maintain the radial distance from the inside. Although the one bushing can't move freely doesn't control the arm from moving back and forth, this motion is constrained by a separate link or radius rod. In the wishbone structure, it is not the same; wishbones are triangular and have two inboard bearings which are narrowly spaced. These bearings confine the outboard end of the wishbone from moving back and forth, thereby controlling two degrees of freedom, and without authorizing further connections. Most control arms form the bottom of a suspension chain. In few layouts, they are used as the upper connection, typically with lower wishbone and the upper arm is attached to the extra radius.
What is the purpose of Rear Control Arm?
The aim of the control arm is to ensure that when passing bumpy roads, the vehicle doesn't encounter too much movement. The control arm connects the hub wheel and steering knuckle to the vehicle's frame. Control arm bushings play an important role in ensuring comfort and smooth handling while driving. We do so by serving as a buffer to the suspension system that then absorbs the vibration, thereby offering a smoother, smoother ride over bumps and even during sharp turns.
How Rear Control Arm Works?
The control arm works extremely mechanically. It is connected to the steering knuckle on one end via a ball joint which is attached to the wheel via a hub and bearing assembly. The other end is fixed to the frame / body of the vehicle. Whenever the vehicle hits the bump, the control arm begins the job by pivoting with the wheel up and down and allowing the vehicle's body to stay stable. The control has one or a pair of bushings on the frame / body side which allows it to pivot this way.
Where is Rear Control Arm Located?
The control arm connects the hub wheel and steering knuckle to the vehicle's frame. Equipped with bushings on the vehicle's frame side, there is also a ball joint on the vehicle's wheel side. This helps in both flex and smooth movement as per road conditions, and driver feedback steering.
