Steering Axis Inclination Definition
Steering Axis Inclination Definition. The steering axis inclination (sai) is the angle between the centerline of the steering axis and vertical line from center contact area of the tire (as viewed from the front). Kingpin angle (like castor angle) contributes to wheel camber change with steering input.
The steering axis inclination (sai) is the angle between the centerline of the steering axis and vertical line from center contact area of the tire (as viewed from the front). The ‘steering axis’ is the axis around which the wheel assembly swivels as it turns to the right or left. The king pin inclination of an axis of turn provides weight stabilization and steady movement of the automobile on a straight line and in turns.
Steering Axis Inclination (Sai) Is The Tilt Of The Steering Axis From Vertical As Viewed From The Front.
Of the steering arm, where the tie rod connects, and a symmetrical part attached to the knuckle, like the axle joint or bearing assembly. It's an angle formed by a line through the centers of the lower and upper ball joints of the strut mount. Purpose of steering axis inclination :

Effects of sai [ edit ] sai urges the wheels to a straight ahead position after a turn. Steering axis inclination according to the free engineering dictionary. The steering axis inclination, θ, is defined as the angle measured in the front elevation between the steering axis (sometimes referred to as the ‘kingpin’ axis from the days when a physical pin was used within a beam axle assembly) and the vertical.
The ‘Steering Axis’ Is The Axis Around Which The Wheel Assembly Swivels As It Turns To The Right Or Left.
This measurement helps determine if the steering arm is moved in or out in relationship to its intended location. With a positive kingpin angle, the outside. Steering axis inclination (sai) is the angle measured between true vertical and the inward tilt of the steering knuckle, king pin or mcpherson strut tube.
Steering Axis Inclination Is Set By The Dimensions Of The Upright And Therefore No Adjustable Once It Defined.
The steering axis inclination (sai) angle has a direct effect on steering and handling because it causes the wheel spindle to angle downward slightly as the wheel is steered. The angle between the vehicle line and center of the kingpin or steering axis, when viewed from the front of the vehicle, is known as kingpin inclination. Also called steering axis inclination.
Caster, Which Is The Forward Or Rearward Tilt Of The Steering.
The amount the steering axis is tilted from true vertical. This definition appears frequently and is found in the following acronym finder categories: Steering axis inclination is built into the knuckle and is not adjustable.
