Infiniti G37 Control Arm With Ball Joint
About control arm with ball joint
The Control Arm forms an integral part of the automatic suspension system. It is also known as the A-arm, and is essentially a hinged suspension bridge that holds the wheel between the axle and the upright or hub suspension. The control arm with ball joint has many sections, and the inside (chassis) end of a control arm is connected by a single pivot which is usually a rubber bushing. This enables it to manage the outboard end position in a single degree of freedom, thus preserving the radial distance from the inside brace. Most control arms form the bottom of a suspension link. They are used as the upper link in few vehicle designs, usually with a lower wishbone. The extra radius rod is then placed on the upper arm.
What is the purpose of control arm with ball joint?
The control arm is primarily attached to the vehicle frame by the wheel hub and steering knuckle. For driving comfort and handling, the Control Arm bushings are important. They help stabilize the suspension system, which allows noise and vibrations to be controlled, as well as offering a smoother ride over bumps.
How control arm with ball joint works?
We need to learn first how the control arm is attached to the vehicle to be able to understand how it works. On one end the control arm is connected by a ball and socket called a ball joint to the steering knuckle (at which the wheel is attached via the hub and bearing assembly). The other end of it is attached to the frame / body of the vehicle. And if the vehicle goes over a bump, the control arm pivots with the wheel up and down and allows the body of the vehicle to stay steady. The control arm also has a bushing (or a pair of bushings) on the side of the frame / body so it can rotate smoothly.
Where is control arm with ball joint located?
The control arm attaches the hub wheel and steering knuckle to the vehicle's frame. The come is fitted with bushings on the vehicle's frame side and a ball joint on the vehicle's wheel side allowing adjustable and controlled movement according to the driver's road conditions and steering feedback.
