Why Castor is important in a vehicle?

Caster affects the steering ease and the stability of the vehicle in a straight line. Modern cars use positive caster in order to resist unintentional turning of the vehicle, or wandering/straying from the intended path, when traveling straight at speed.

What is caster angle on a car?

Caster is the angle that identifies the forward or backward slope of a line that is drawn through the upper and lower steering pivot points. It does not affect tire wear, but caster does have an influence on the directional control of the steering.

What is a good caster angle?

Positive caster angles run between 3 – 5° on modern vehicles. This gives a good mix of highway stability and steering feel. For a more performance oriented setup on a MacPherson strut you can add a degree or two to have more favorable camber gain at high steering angles.

Does caster affect braking?

Negative caster gives no feedback to the driver in terms of wheel position. A further disadvantage of negative caster is that it will increase under braking conditions making the steering more unstable due to the car pitching forward. This can however be solved with anti-dive steering geometry.

What is the function of caster?

A caster (or castor) is an undriven wheel that is designed to be attached to the bottom of a larger object (the “vehicle”) to enable that object to be moved. Casters are used in numerous applications, including shopping carts, office chairs, toy wagons, hospital beds, and material handling equipment.

What is castor and camber angle?

Caster is the angle between the verticle line and kingpin centre line in the plane of the wheel when the viewed from the side is called the caster angle. Camber is the angle between the centre line of the tyre and vertical line viewed from the front of the vehicle is known as the camber angle.

Is caster a pulling angle?

So: Camber and caster will cause your vehicle to pull if they’re uneven, but will cause little tire wear, while toe in won’t cause your vehicle to pull, but can cause extremely fast tire wear. This is why your vehicle can pull and not wear out tires, or it can drive perfectly straight and destroy them in a hurry!

What is castor angle in steering?

Castor or Caster angle Simply, caster angle is the steering axis’ angle of inclination to the the vertical. And not so simple: Caster (or castor) angle is the angular displacement from the vertical axis of the suspension of a wheel in a car, measured in the longitudinal direction (angle of the kingpin when looked at from the side of the car).

What is caster angle and how is It measured?

Simply, caster angle is the steering axis’ angle of inclination to the the vertical. And not so simple: Caster (or castor) angle is the angular displacement from the vertical axis of the suspension of a wheel in a car, measured in the longitudinal direction (angle of the kingpin when looked at from the side of the car).

What is negative caster angle in cars?

Technically, the negative caster is the opposite of the positive one. Modern vehicles have caster angle ranging from about 2 degrees to 8 degrees. Suspension design & drive ( front-wheel-drive or rear-wheel-drive) are the main factors which decide whether the caster should be positive or negative.

What is the caster angle in motorcycles?

Two-wheelers such as scooters & motorcycles also have the caster angle. The angle between the forks/shock absorbers center and the vertical line forms the ‘Caster’ angle in motorcycles.
