| - 12 - would still have a tendency to self-centre due to the different inclinations of the stub axle on a lock. This is illustrated in sketch C. (f) Wheel camber. As we have previously shewn, in order to obtain centre-point steering, it is necessary to give the pivots considerable transverse inclination. To reduce this, the wheel is also frequently inclined to the vertical slightly. The inclination rarely exceeds 3°. This is termed 'wheel camber'. An advantage claimed for this practice is that on highly cambered roads the plane of the wheel is more nearly normal to the plane of the road than if the former was vertical. In our opinion this is of little practical significance. [Image of a blueprint diagram titled: ANGLE OF WHEEL CAMBER.] (g) Wheel-gather, or toe-in. The front wheels of a car, looked at in plan, frequently 'look in' slightly. The main reason for this is to prevent the wheels splaying when any wear takes place in the cross steering tube. contd. | ||
