A multi-link type rear independent suspension on an AWD car. The anti-roll bar has some yellow paint on it. Independent suspension is any automobile suspension system that allows each wheel on the same axle to move vertically (i.e. reacting to a bump on the road) independently of the others.
A short long arms suspension (SLA) is also known as an unequal-length double wishbone suspension. The upper arm is typically an A-arm and is shorter than the lower link, which is an A-arm or an L-arm, or sometimes a pair of tension/compression arms. In the latter case, the suspension can be called a multi-link, or dual-ball joint suspension.
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 ...
The Tilting Suspension System [27] (also known as the Leaning Suspension System) is not a different type or geometry of construction; moreover, it is a technology addition to the conventional suspension system. This kind of suspension system mainly consists of independent suspension (e.g., MacPherson strut, A-arm (double wishbone)). With the ...
It is an independent suspension system, as each tyre rises and falls without affecting the position of the other. Although each tyre still moves in an arc as in a standard swing-axle suspension, the lower control arms effectively are lengthened by attaching the axle pivot point to the bottom of the opposite frame rail (i.e., the left lower ...
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 ...
In 1947 Earle MacPherson patented the MacPherson strut for use on the Chevrolet Cadet. [4] [5] This was the first true strut suspension for cars: the stub axle was rigidly fixed to the strut, thus always keeping the same angle with it, rather than being attached through a swivelling joint as for Stout's Scarab.
The MacPherson strut is a common form of strut suspension. This was not the first attempt at strut suspension, but in MacPherson's original patent, the anti-roll bar forms an integral and essential part of the suspension, in addition to its usual function in controlling body roll. A strut suspension like MacPherson's requires a hinged lower ...
