caster angle formula

Positive Caster: Positive caster is when the steering axis is in front of the vertical. You have toe-in when the tires point in towards each other, and toe-out when they point away from each other. So I have either 3 degrees Caster or 4.3 degrees (3X1.432=4.296) Caster. 1.7. With the wheels on the turntables and pointing straight ahead, zero your turntables. Caster also … Caster angles are generally used to improve a vehicle’s steering balance and front-end cornering stability. That being said, changing this angle is generally more mechanically intensive, as it will require changing out the hard parts that make up your suspension. Turned 20 degrees out and read the angle. Is this an accurate way to find 20 degrees of turn? 1.7.1. Part 2: https://youtu.be/oh535De4hKgSprings and Anti-roll bar video: https://youtu.be/NFGkZNrNTIE Caster Angle. Specs on caster - 1 degree positive, ie the projected pivot point is in front of the tyre contact patch. The angle between the king-pins or ball-joints center line and the vertical line forms Caster angle as seen from the side. Caster is a little less obvious. If you look at a bicycle from the side, the top of the spindle is angled rearward toward the rider. And this formula: Caster (deg) = (180 / 3.1415) * [(camber1 - camber2) / (turnangle1 - turnangle2)] ... You already know how to measure the camber angle so this is how to measure the caster. CASTER DEFINEDCaster is a design condition that, in addition to the spindle kingpin angle, serves to cause a wheel to want to track straight ahead.A … This self-centering effect is achieved by tilting the king-pin from the top. Caster Angle: It is the Forward or rearward inclination of the steering axis. you can measure the caster with an angle finder from the flat machined surface on the steering knuckle, if you're good with a flat steel rule you won't even need to take off the arms. The purpose of this is to provide a degree of self-centering for steering the wheel casters around, so as to trail behind the axis of steering. You have no toe if the tires are parallel to each other, along the direction of the car. Toe is the angle the tires are rotated around their vertical axis, looking at them from above the car. the caster angle works in conjunction with the king pin inclination to define the wheel turning axis in space and creates the noted camber changes and resulting incurred suspension dynamics. The second distinguishing function of the caster angle is to create mechanical trail. I have seen conflicting information on this. https://www.freeasestudyguides.com/steering-caster-chart.html The effect of camber on available grip For this, the king-pins (in rigid suspension) or ball-joints (in independent front suspension) slightly tilt from the vertical line. I have read that this difference is the Caster and I have seen formulas for (difference in degrees from 20 out to 20 in) X 1.432 = Caster.
