Suspension geometry refers to all dimensional and kinematic characteristics of a mechanical system between the sprung part (the body) and the wheel of a vehicle. It also defines degrees of freedom as regards the suspension, which is usually corrected by wheel alignment Houston. The term geometry is sometimes confused with parallelism, which indicates the parameters of steering geometry. This is essentially the suspension geometry that affects handling of vehicles. All the work of a technician entails vehicle geometry for optimal behavior in terms of road holding, therefore active safety, comfort and endurance.
Note, paths are measured between the axles of wheels and not between the outer faces. These three variables have a predominant role as regards the dynamic behavior of vehicles. They are to be considered depending on center of gravity relative to wheel axis. Both terms refer to the same specificity, the front and rear, respectively.
To ensure the tire stays perpendicular to the ground when the car moves, it gives a negative camber at rest. Normally, the camber is set and fixed to wear in a uniform (cylindrical) fashion around the tire. A strong negative camber is proof of good cornering grip. This is in contrast to weak grip during acceleration or braking in a warped line (the tire is not really flat on the road and the wheels are not supported when turning).
Conversely, a low negative camber will promote straight lines and inhibit speed cornering. For sports cars participating in circuits, the optimum value of camber is specifically set for a given circuit. This maybe the result of a compromise, because where the car will gain traction in cornering, it will lose recovery and brake lines.
Sometimes the wheelbase is different on the right and left as with the Renault 16 and Renault 4 wherein the torsion bars of suspension are too long to be placed in relation to head-mounting spade, which imposes an offset on rear wheels. This is the distance, on the same axle between the axis of contact zones of wheels.
Hunting generates a self-alignment of steering wheels in the axis of movement of a vehicle. The caster angle is measured in degrees and minutes of angle whereas the offset hunting is measured in inches or millimeters. The parallelism is the most common setting on cars - but it is not always adjustable.
Pinching and running gear are arranged differently, depending on the architecture of the car concerned. In general, the nip is found on the rear wheels, because it stabilizes and limits the rear axle. Conversely, the opening is often found on the front wheels. There are two reasons for this: most cars today are pulls.
The trend in competition is to focus mass to improve the agility a vehicle by reducing its inertia in terms of vertical axis passing through the center of gravity. WRC and the door overhang are artificially increased by the addition of front and rear bumpers for the car to meet technical regulations (such as the 206 WRC where the use of shields is caricatured so that the car measures the correct length).
