Shock absorbers damp out the (otherwise simple harmonic) motions of a vehicle up and down on its springs. They must also damp out much of the wheel bounce when the unsprung weight of a wheel, hub, axle, and sometimes brakes and the differential bounces up and down on the springiness of a tire.
Shock absorbers are an important part of car suspension designed to increase comfort, stability and overall safety. The shock absorber, produced with precision and engineering skills, has many important features. The most common type is a hydraulic shock absorber, which usually includes a piston, a cylinder, and an oil-filled chamber.
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).
An active suspension is a type of automotive suspension that uses an onboard control system to control the vertical movement of the vehicle's wheels and axles relative to the chassis or vehicle frame, rather than the conventional passive suspension that relies solely on large springs to maintain static support and dampen the vertical wheel movements caused by the road surface.
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 ( mechanical abrasion ...
Showa was an official IndyCar Series dampers, springs and shock absorber supplier from 2007 to 2011 alongside Penske Racing Shocks which only supplying shocks for Team Penske. Showa remained IndyCar Series shock absorber supplier since 2012 but only for Honda -powered teams.
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.
The spindle of the shock absorber now became the upper suspension pivot, usually double-ended. One of the last mass-production sports cars to still use lever arm shock absorbers was the MG B. [8] This had a lever arm shock absorber as the upper wishbone. A popular handling upgrade in later years was to fit telescopic shock absorbers instead.
