Steering Geometry 1
1)
i.Caster = 5.37 degree
ii.Mechanical trail = - 9.41 mm Left side axis considered
iii.Kingpin inclination angle = 10 degrees
iv.Scrub radius = 32.35mm
v.Kingpin lateral offset or spindle length = 85.92 mm
2)
Lateral Force (Fy ) = 2000
Pneumatic Trail ( PT) = 25mm
Mechanical Trail (MT ) = 9.4mm
Restoring Moment = Lateral force * ( PT + MT) =
2000*(25+9.4)
= 68.8 kN
3. Hardpoint recommendation to change the sign of the scrub radius
- Move the UCA Knuckle Ball Joint away from the wheel axis or LCA Knuckle Ball Joint towards the wheel axis so that the slope (tilt) of the line 5-2 increases and we obtain an intersection on the other side of the axis
