A typical ball joint with cutaway view (right) An inner tie rod end cut open to expose the ball joint. In an automobile, ball joints are spherical bearings that connect the control arms to the steering knuckles, and are used on virtually every automobile made. [1] They bionically resemble the ball-and-socket joints found in most tetrapod ...

Commonly, springs are mounted on control arms, swing arms or some other pivoting suspension member. Consider the example above, where the spring rate was calculated to be 500 lbs/inch (87.5 N/mm), if one were to move the wheel 1 in (2.5 cm) (without moving the car), the spring more than likely compresses a smaller amount.
A rod end bearing, also known as a heim joint (N. America) or rose joint (U.K. and elsewhere), is a mechanical articulating joint. Such joints are used on the ends of control rods, steering links , tie rods , or anywhere a precision articulating joint is required, and where a clevis end (which requires perfect 90-degree alignment between the ...
These rods are connected with a socket arrangement similar to a ball joint, called a tie rod end, allowing the linkage to move back and forth freely so that the steering effort will not interfere with the vehicles up-and-down motion as the wheel moves over roads.
A link differs from a control arm because it can only control one of the degrees of freedom by itself. In the attached photo of a 5-link live axle suspension, the different types of links can be seen. These links work in tandem with the coil springs, dampers, and sway bar to control all six degrees of freedom of the axle. The upper links ...
Push-rod and pull-rod suspension are similar yet distinct in design, with the main difference being the placement of the rocker arm that controls shock damping in relation to the upper control arm. In effect, this means that both push-rod and pull-rod systems are functionally the same design. [5] [6] In a push-rod suspension system, there is an ...
