CASTOR ANGLE Meaning and
Definition
-
The castor angle, also known as the kingpin inclination or steering axis inclination, is a crucial automotive parameter that defines the angle between the steering axis and a vertical line when viewed from the side of a vehicle. It is an essential element in determining the stability, handling, and maneuverability of an automobile, particularly during steering maneuvers.
To comprehend the castor angle, one must understand the steering system of a vehicle. The steering knuckles pivot on ball joints, enabling the wheels to turn left or right. The line joining these ball joints is the steering axis, which is tilted backward or forward from the vertical line. This tilt defines the castor angle.
Generally, the castor angle is positive, meaning the steering axis tilts backward from the vertical line. The purpose of this inclination is multifaceted. Primarily, it contributes to vehicle stability and straight-line tracking. When the wheels encounter an irregularity on the road, the castor angle generates a self-centering effect, causing the wheels to return to the straight-ahead position. Additionally, the castor angle aids in steering feedback, as it permits the wheels to lean into a turn, enhancing cornering stability.
Different vehicles necessitate varying degrees of castor angle, depending on their intended purpose. Front-wheel drive cars typically have a smaller castor angle compared to rear-wheel drive vehicles, which require a larger castor angle for better high-speed stability. Consequently, the castor angle is carefully calibrated during the design and manufacturing stages of vehicles to strike a balance between stability, maneuverability, and overall handling characteristics.

Etymology of CASTOR ANGLE
The term "castor angle" is derived from the combination of two different words - "castor" and "angle". Here's a breakdown of their etymology:
1. Castor: The word "castor" has its origins in Ancient Greek. It comes from the Greek word "kastor" (κἀστωρ), which means "beaver". In the context of the castor angle, "castor" refers to the castor wheel or castor, a type of wheel that is commonly used in furniture and other items to provide mobility.
2. Angle: The term "angle" has its roots in Latin. It comes from the Latin word "angulus", which means "corner" or "angle". In the context of the castor angle, "angle" refers to the steering angle or inclination at which a castor wheel is mounted.
