Sprung mass 3655251 225408823 2008-07-13T15:04:22Z Dcgibbons 1349415 fix spelling of deleterious In a vehicle with a [[suspension (vehicle)|suspension]], such as an [[automobile]], [[motorcycle]] or a [[tank]], '''sprung mass''' (or '''sprung weight''') is the portion of the vehicle's total mass that is supported above the suspension, including in most applications approximately half of the weight of the suspension itself. The sprung weight typically includes the body, frame, the internal components, passengers, and [[cargo]], but does not include the mass of the components suspended below the suspension components (including the [[wheel]]s, wheel bearings, brake rotors, calipers, and/or [[caterpillars track]]s, if any), which are part of the vehicle's [[unsprung weight]]. The larger the ratio of sprung weight to [[unsprung weight]], the less the body and vehicle occupants are affected by bumps, dips, and other surface imperfections such as small bridges. However, a large sprung weight to unsprung weight ratio can also be deleterious to vehicle control.{{Fact|date=October 2007}} [[Category:Mass]] [[Category:automotive suspension technologies]] {{automotive-tech-stub}} [[es:Masa suspendida]]
