1. Accurate front wheel alianment is essential to provide good

steering and roadholding characteristics and and to ensure slow and even

tyre wear. Before considering the steering angles, check that the tyres

are correctly inflated, that the front wheels are not buckled, the hub

bearings are not worn or incorrectly adjusted and that the steering

linkage is in good oeder, without slackness or wear at the joints.

2. Wheel alignment consists of four factors:

Camber, is the angle at which the road wheels are set from the vertical

when viewed from the front or rear of the vehicle. Positive camber is

the angle (in degrees) that the wheels are tilted outwards at the top

from the veertical.

Castor, is the angle between the steering axis and a vertical line when

viewed from each side of the vehicle. Positive castor is indicated when

the steering axis is inclined towards the rear of the vehicle at its upper

end.

Steering axis inclination, is the angle when viewed from the front or

rear of the vehcile between vertical and an imaginary line drawn

between the upper and lower strut mountings.

Toe, is the amount by which the distance between the front inside

edges of the roadwheel rims differs from that between the rear inside

edges. If the distance between the front edges is less than that at the

rear, the wheels are said to toe-in. If the distance between the front

inside eddes is greater than that at the rear, the wheels toe-out.

3. Camber and castor are set during production. Any deviation from

specified tolerances must therefore be due to collision damage or

grossly worn suspension components.

    1. 正確的前輪定位對於提供良好的轉向和抓地特性是很重要的,同時還能確保緩慢又平均的輪胎磨耗。在考慮轉向角度之前,檢查輪胎是否充氣正確,前輪沒有變形,輪轂軸承沒有磨損或調整錯誤,還有轉向連桿情況良好,沒有鬆動或接頭磨損。

    2. 輪胎定位包含四個要素:

    外傾角 (Camber) 是從車前或車後觀察輪胎設定和垂直所形成的角度。 正外傾角 (Positive camber) 是輪胎上端由垂直向外傾斜的角度 (用度數計算)

    後傾角(Castor) 是從車的兩邊觀察轉向軸中心線與垂直線間的角度。 正後傾角 (Positive castor) 是當輪胎上端的轉向軸中心線向後傾斜。

    內傾角或轉向軸傾斜角 (Steering axis inclination) 是從車前或車後觀察上下球接頭 (大王銷)假想中心線與垂直之間的角度。

    束角 (Toe) 是前輪內前緣距離和內後緣距離在與軸同高處之差。如果前緣距離比後緣距離小,此前輪稱為前束(toe-in),反之稱為後束 (toe-out)。

    3. 外傾角和後傾角是在製造時設定。任何偏離設定容許差都是因為撞擊受損或通常是磨損的懸吊系統零件磨損。
