Caster causes a wheel to align with the direction of travel, and can be accomplished either by caster displacement or caster angle. Caster displacement moves the steering axis ahead of the axis of wheel rotation, as with the front wheels of a shopping cart. Caster angle moves the steering axis from vertical. [3]
If excessive camber — either positive or negative — is applied, the vehicle's tires will wear unevenly, a condition known as "camber wear". A suspension with excessive negative camber places more load on the inboard shoulder of the tire, causing the inboard shoulder to wear out quicker than the outboard shoulder.
Zero scrub radius (top) positive scrub radius (center) negative scrub radius (bottom) In an automobile's suspension system, the scrub radius is the distance in front view between the king pin axis and the center of the contact patch of the wheel, where both would theoretically touch the road. It can be positive, negative or zero.
There are some car models with different factory setting for right and left side wheelbase length, for various design reasons. An off-spec setback may occur because of a collision or a difference between right and left caster. [2] Rake is the difference between the front and rear ride heights, a positive number when the rear ride height is larger.
False positive COVID-19 tests—when your result is positive, but you aren’t actually infected with the SARS-CoV-2 virus—are a real, if unlikely, possibility, especially if you don’t perform ...
A positive caster angle aids in directional stability, as the wheel tends to trail, but a large angle makes steering more difficult. Curves described by the rear wheels of a conventional automobile. While the vehicle moves with a constant speed its inner and outer rear wheels do not.
