On some cars, not all of these can be adjusted on every wheel. These three parameters can be further categorized into front and rear (with no caster on the rear, typically not being steered wheels). In summary, the parameters are: Front: Caster (left & right) Front: Camber (left & right) Front: Toe (left, right & total) Rear: Camber (left & right)
Uneven or accelerated tire wear: can be caused by under-inflation, overloading or poor wheel alignment. Increased tread wear on only one side of a tire: often a sign of poor wheel alignment. Tread worn away completely: especially when the wear on the outer rubber exposes the reinforcing threads within, the tire is said to be bald and must be ...
Change in camber due to cornering forces can cause loss of rear-wheel adhesion leading to oversteer—a dynamically unstable condition that can cause a vehicle to spin. This is an especially severe problem when a swing axle is used in a rear-engine design, because of the greater side-g forces on the rear wheels from the mass of the engine.
Most modern rear-wheel-drive cars solve this problem by using a form of traction control, such as anti-lock brakes, which limits engine power when fishtailing occurs. Similar behavior is evident during heavy braking in all types of road vehicles due to weight transfer to the front. This can be mitigated by re-proportioning the braking forces ...
Ackermann geometry. The Ackermann steering geometry (also called Ackermann's steering trapezium) [1] is a geometric arrangement of linkages in the steering of a car or other vehicle designed to solve the problem of wheels on the inside and outside of a turn needing to trace out circles of different radii.
Vibration in automobiles may occur for many reasons, such as wheel unbalance, imperfect tire or wheel shape, brake pulsation, and worn or loose driveline, suspension, or steering components. Unbalance can result from collision-induced wheel deformations, uneven tire wear, or a shift of the tire on the rim.
Three-wheeled cars/vehicles have unique handling issues, especially considering whether the single wheel is at the front or back. (Motorcycles with sidecars; another matter.) Buckminster Fuller's Dymaxion car caused a sensation, but ignorance of the problems of rear-wheel-steering led to a fatal crash that destroyed its reputation.
The 1960 Milliken MX1 Camber Car has a large negative camber. Camber angle is one of the angles made by the wheels of a vehicle; specifically, it is the angle between the vertical axis of a wheel and the vertical axis of the vehicle when viewed from the front or rear.
