Ball Joint - Theory

Theory

A ball joint is used for allowing free movement in two planes at the same time, including rotating in those planes. Combining two such joints with control arms enables motion in all three planes, allowing the front end of an automobile to be steered and a spring and shock (damper) suspension to make the ride comfortable.

Unlike a kingpin suspension, this allows for adjusting the camber and caster of the wheel suspension. Both systems allow adjustment of the toe angle. This ability to fine tune the suspension allows manufacturers to make the automobile more stable and easier to steer, compared to the older kingpin style suspension. The smoother ride also increases tire tread life, since the ball-joint suspension allows the vehicle to be adjusted to track in a level fashion.

Famous quotes containing the word theory:

    There is in him, hidden deep-down, a great instinctive artist, and hence the makings of an aristocrat. In his muddled way, held back by the manacles of his race and time, and his steps made uncertain by a guiding theory which too often eludes his own comprehension, he yet manages to produce works of unquestionable beauty and authority, and to interpret life in a manner that is poignant and illuminating.
    —H.L. (Henry Lewis)

    Every theory is a self-fulfilling prophecy that orders experience into the framework it provides.
    Ruth Hubbard (b. 1924)

    The theory of the Communists may be summed up in the single sentence: Abolition of private property.
    Karl Marx (1818–1883)
