the bump primarily affects only the contacted wheel. This offers many advantages such as greater ride comfort, better traction, and safer, more stable vehicles on the road. Types Double wishbone suspension In automobiles, a double wishbone suspension is an independent suspension design using two (occasionally parallel) wishbone-shaped arms to locate the wheel. Each wishbone or arm has two mounting points to the chassis and one joint at the knuckle. The shock absorber and coil spring mount to the wishbones to control vertical movement. Double wishbone designs allow the engineer to carefully control the motion of the wheel throughout suspension travel, controlling such parameters as camber angle, caster angle, toe pattern, roll center height, scrub radius, scuff and more. Multi-link suspension A multi-link suspension is a type of vehicle suspension design typically used in independent suspensions, using three or more lateral arms, and one or more longitudinal arms. A wider definition considers any independent suspensions having three control links or more multi-link suspensions. 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 prototype and put into production later on their W201 and W124 series. MacPherson strut 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. This system was popularized in British Fords in the 1950s, then adopted by BMW (1962) and Porsche (1963). Later, this space-efficient system became widespread with the growing popularity of front-wheel drive vehicles. One problem with this system is that once the spring or the top plate becomes worn, the driver of a car with this system may hear a loud "clonk" noise at full lock (i.e. steering wheel turned to the extreme left or extreme right positions), as the strut's spring jumps back into place. This noise is often confused with CV-joint knock. Transverse leaf-spring Several independent suspension designs have featured transverse leaf springs. Most applications used multi-leaf steel springs, although more recent designs have used fiber reinforced plastic (FRP, typically fibers are fiberglass) springs. In addition to spring type (multi-leaf steel, FRP), a distinction can be drawn between systems where the spring also acts as a locating link and those
