what mainly produces steering self centering
A positive caster angle produces a self-centering action of steering, and gives a steering feedback for the driver in straight line. This makes a vehicle easier to drive with a better steering response and directional stability.ue to this caster angle, a power steering is usually used by manufacturers. With a positive mechanical trail, the wheel is âpulledâ by the vehicle as a wheel of a shopping trolley. Thus, it produces a self-righting effect in straight line which affects the vehicleâs straight-line stability.
