the vehicle weight not supported by the springs, including the steering knuckle, brake assembly, tire and wheel.
This refers to all parts of the vehicle that are not supported by the suspension system, wheels, tires, etc. Also see sprung weight.
The weight of car components not supported by the springs (wheels, tires, brakes, rear axle, control arms, etc.).
measurement of the weight of everything outboard of the wishbones or suspension links, plus 1/2 of the weight of the wishbones or links and spring/shock. It has a great effect on handling. Here is a diagram below showing why unsprung weight is so important.
Weight of moving components when they're not moving, which contain potential energy. Typically referred to rotating mass (such as with wheels, brake rotors, clutch, flywheel, driveshaft, etc.), but is also used to describe suspension components that have movement. Unsprung weight is a racecar's enemy because it uses up energy that could otherwise be applied to increasing speed.
The weight of vehicle components not supported by the springs. Parts included are the wheels, tires, rear axle (but not always the differential), steering linkage, and some suspension parts.
( noun) The weight of parts of the motorcycle that is not supported by the suspension (wheels, axles, brakes, etc.).
The part of the car, which is not supported by the springs. acuum advance - System of ignition advance and retard used in some distributors where the vacuum in the engine inlet manifold is used to act or a diaphragm which alters the ignition timing as the vacuum changes due to the throttle position.
Components such as tires, wheels and brakes are not supported by the suspension and are considered unsprung weight. Reducing unsprung weight improves ride and handling by allowing the tires to respond more rapidly to road irregularities An independent rear suspension reduces unsprung weight by attaching the differential to the chassis rather than solidly mounting it with the axis

In a ground vehicle with a suspension, the unsprung weight (or, more properly, the unsprung mass) is the mass of the suspension, wheels or tracks (as applicable), and other components directly connected to them, rather than supported by the suspension. (The mass of the body and other components supported by the suspension is the sprung mass.) Unsprung weight includes the mass of components such as the wheel spindles, wheel bearings, tires, and a portion of the weight of driveshafts, springs, shock absorbers, and suspension links.
