Steering Geometry 1

1)

i) Caster = 5.38°

ii) Mechanical Trail = 9.41 mm

iii) Kingpin inclination angle = 10.01°

iv) Scrub radius = 32.35 mm

v) Kingpin lateral offset or spindle length = 85.29 mm

The detailed solution can be found in the attached excel sheet.

2)

Given:-

Pneumatic Trail = 25 mm

Lateral Force = 2000 N

Solution:-

Restoring moment at the point of intersection of kingpin to the ground in side view is given by

Restoring moment = Lateral Force * (Mechanical Trail + Pneumatic Trail)

= 2000 * (9.41 + 25)

= 68820 Nmm

Restoring moment = 68.82 Nm

3)
