A simple MacPherson strut suspension on the left front wheel of a rear-wheel drive vehicle. The front of the vehicle is at bottom right of the image. Upper green: Vehicle body/strut interface Red: Steering knuckle or hub carrier Blue: Lower control arm or track control arm Light blue: Steering gear tie rod or track rod Lower purple: Radius rod
Automotive suspension design is an aspect of automotive engineering, concerned with designing the suspension for cars and trucks. Suspension design for other vehicles is similar, though the process may not be as well established. The process entails Selecting appropriate vehicle level targets; Selecting a system architecture
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 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 ...
A multi-link suspension is a type of independent vehicle suspension having three or more control links per wheel. [1] These arms do not have to be of equal length, and may be angled away from their "obvious" direction. It was first introduced in the late 1960s on the Mercedes-Benz C111 [2] and later on their W201 and W124 series. [3] [4]
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 ...
A single wishbone or A-arm can also be used in various other suspension types, such as variations of the MacPherson strut. The upper arm is usually shorter to induce negative camber as the suspension jounces (rises), and often this arrangement is titled an "SLA" or "short, long arms" suspension. When the vehicle is in a turn, body roll results ...
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 ...
