The MacPherson strut is a type of automotive suspension system that uses the top of a telescopic damper as the upper steering pivot. It is widely used in the front ...
Multi-link suspension allows the auto designer the ability to incorporate both good ride and good handling in the same vehicle.. In its simplest form, the multi-link suspension is orthogonal—i.e., it is possible to alter one parameter in the suspension at a time without affecting anything else.
Earle Steele MacPherson (July 6, 1891 – January 26, 1960) was an American automotive engineer, most famous for developing the MacPherson strut in the 1940s. Biography [ edit ]
MacPherson strut (painted black) on Proton Exora. This is the most common, widely used front suspension system in cars today. It is a very simple and effective design that uses a strut-type spring and shock absorber that work as a team that will pivot on a single ball joint.
MacPherson strut suspension, track control arm coloured dark blue. In automotive suspension, a control arm, also known as an A-arm, is a hinged suspension link between the chassis and the suspension upright or hub that carries the wheel. In simple terms, it governs a wheel's vertical travel, allowing it to move up or down when driving over ...
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 ...
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 ...
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.
