English: Front right wheel of a Mercedes Vito utility van. The unusual angle is due to a ball joint failure - probably resulting from hitting a kerb too hard. The ball joint (dark protrusion at the outer tip of the lower control arm, by the tire sidewall) is no longer attached to the knuckle.
The torque tube surrounded the true driveshaft and exerted the force to its ball joint at the extreme rear of the transmission, which was attached to the engine. A similar method like this was used in the late 1930s by Buick and by Hudson 's bathtub car in 1948, which used helical springs that could not take fore-and-aft thrust.
Ball joints allow a limited range of smooth movement in all directions Ball Joint Animation. A ball joint is used for allowing free rotation in two planes at the same time while preventing translation in any direction, [1] including rotating in those planes. Combining two such joints with control arms enables motion in all three planes ...
Front suspension of a race car — the caster angle is formed by the line between upper and lower ball joint An example of a chopper with a raked fork at an extreme caster angle The caster angle [ 1 ] or castor angle [ 2 ] is the angular displacement of the steering axis from the vertical axis of a steered wheel in a car , motorcycle ...
The two arms, the spindle, and the body, form a four-bar link.Use of the linkage at the lower suspension connection of either a MacPherson strut or a short long arms suspension readily gives an effective virtual ball joint outboard of the spindle, which is very useful for a suspension designer, allowing negative scrub radius whilst allowing the ball joints to move in and thus out of the way of ...
Cascading failure is a common effect seen in high voltage systems, where a single point of failure (SPF) on a fully loaded or slightly overloaded system results in a sudden spike across all nodes of the system. This surge current can induce the already overloaded nodes into failure, setting off more overloads and thereby taking down the entire ...
An older vehicle with loose steering or "play in the steering wheel" is often found to have a worn rag joint. One can reach inside the cab and wiggle the steering wheel while watching the rag joint move without the input shaft moving. This condition may cause the vehicle to fail the vehicle inspection, indicating that the worn part needs ...
Ball splines where the grooves of the inner and outer parts are formed as linear races filled with ball bearings to allow for free linear motion even under high torque. To allow longer travel the outer spline can incorporate channels to re-circulate the balls, in this way torque can be transferred from a long shaft while travelling up or down ...
