  Caster angle control system for vehicles - Patent 5839749
The caster angle control system of claim 1, wherein said strut assembly passes through a portion of a wheel housing of the vehicle, a front and a rear position of the wheel housing.
A caster angle is defined by an angle, in side elevation, between the steering axis and the vertical.
The amount of caster change is controlled in accordance with the variation of the distance from the hole 44 to the outer circumference points a, b and c of the cam 24.

  Caster angle - Biocrawler
Caster angle is the angular measure from the vertical of the suspension of a steered wheel in a car or other vehicle, measured in the longitudinal direction.
It is to the angle between the pivot line (an imaginary line that runs through the center of the upper ball joint to the center of the lower ball joint) and vertical.
The pivot points of the steering are angled such that a line drawn through them intersects the road surface slightly ahead of the contact point of the wheel.

As viewed from the front of the vehicle, the camber angle is the degree to which the wheel tilts inward or outward It is measured in degrees and changes with the load of the vehicle and suspension movement.
When viewed from the side of the wheel, the caster angle is the degree to which the kingpin or ball joint tilts forward or rearward in relation to the frame Like the camber angle, the caster angle is also measured in degrees.
The caster angle is the angle formed at the point where the two lines cross, as viewed from the side of the vehicle.

  Suspension and Steering, Page 3 of 4
Caster angle is the number of degrees that a line, drawn through the center of the upper and lower ball joints (or strut and lower ball joint) and viewed from the side, can be tilted forward or backward.
Positive caster means that the top of the upper ball joint (or strut) is tilted toward the rear of the vehicle, and negative caster means that it is tilted toward the front.
Figure 16 A positive caster angle will have the lower ball joint pivot slightly ahead of the center of the tire and the strut or upper ball joint tilted toward the rear of the vehicle.

 Steering Geometry and Caster Measurement
Caster Angle – The angle, in a vertical longitudinal plane containing the thrust line, between the vertical and the projection of the steering axis onto the plane.
During the caster turn procedure, the alignment technician is required to steer to somewhat precise toe angles and cause the alignment instrument to record the camber and toe angles.
During the turn procedure, the camber sensor is tilted to the front or rear, and the angle it measures is altered by the cosine of the tilt angle.

 etyres - tyre glossary - Caster
The caster angle (more properly “castor”) is the measurement of the difference between the suspension of a wheel and the steering axis.
Viewed from the side, caster angle is the longitudinal difference from vertical and the line between the upper and lower ball joints.
Different displacements of the upper ball joint, changing the caster angle, are used to adjust the desired amount of tendency of tyres to follow in a straight line (“trailing”) or to be “damped” for greater control in cornering.

 Caster
Now, imagine that the caster angle is vertical, meaning that the top and bottom of the steering “kingpin” is directly aligned with the motion of the suspension arms.
The more vertical the caster angle, the less the effective camber change of the wheels, so that ONLY the static camber of the outside wheel is affecting how much the wheels “dig in”.
However, since there is more effective camber at more laid-back caster angles, the “tilted” front wheels are more able to “dig” into the corner, allowing the car to resist centrifugal force and giving it a greater amount of control when exiting a corner.

 R/C In Greece :: What is caster?   (Site not responding. Last check: )
Caster is the angle at which the front steering pivots.
The caster angle affects on- and off-power steering, as it will tilt the chassis more or less depending on how much caster is applied.
The second statement refers to the difference between a vertical line and the caster angle of the steering (or the thickness of spacers placed in FRONT of the upper suspension arm); therefore LESS caster also means a more verticle angle.

 caster
Caster refers to the angle of rear ward lean of the kingpins (the bolts about which the stub axles pivot around).
The greater the caster angle, the greater the increase of negative camber on the outside, laiden wheel, and the more positive camber on the inside, unladen wheel.
Caster also results in changes of the front wheel trim height with changing steering angles: the more camber, then at a given steering angle, the lower the inside wheel and the higher the outside wheel ride height.

Caster describes the angle c between the kingpin and the vertical plane.
The bigger the caster angle, and the heavier the car, the stronger this effect is. Also, the bigger he caster angle, the bigger the camber difference induced when the wheels are steered.
The toe angle is measured in degrees, it's the angle between the centerlines of the two tires.

 [No title]
Caster is a measure of the angle between the steering axis and vertical, as viewed from the side of the vehicle when the wheels are in the straight ahead position.
To increase positive caster on a 4WD vehicle, move the front cam lobe inboard and the rear cam lobe outboard.
The caster angle can be adjusted by varying the length of the strut rod or by means of caster shims installed in position between the frame and fulcrum pins.
