TRANSVERSE PIVOT INCLINATION

OVERALL STEERING EFFICIENCY ASSUMED AS 60% WHEN CALCULATING LOADS ON THE STEERING WHEEL RIM
PIVOT ASSUMED VERTICAL IN LONGITUDINAL ELEVATION TO SIMPLIFY COMPARISON

SERIES. | Inclination of king pins. | Pivot lift at centre to full lock. | Resultant effort lifting car. Mean manual load. Centre to full lock.
T (No F.W.B) | 5° | .0382 | 3.65 lbs.
V (New PhantomCodename for PHANTOM I). | 6° | .0532 | 4.56 lbs.
C2 (New axle) | 2° 30' | .015 | 1.15 lbs.

Comparison of effect of transverse pivot inclination only, i.e. every axle assumed fitted to a "T" series car so that the car wt. and steering ratio remain a constant :-

Type of Axle. | Resultant effort lifting car. Rim of the steering wheel.
T (No F.W.B.) | 3.65 lbs.
V (New PhantomCodename for PHANTOM I). | 5.13 lbs.
C2 (New axle.) | 1.44 lbs.
