Assignment 1

1. 4 degrees of restraint

2. during jounce the negative camber will provide stability and traction

3.1 At CG, the rolling moment is zero

3.2 At ground level, rolling moment is high

3.3 Below ground level, rolling moment is maximum

4. Camber angle can not be changed in a Mc Pherson strut

5. Increasing stiffness of rear suspension

6a. Spring rate refers to the load required to compress the spring by a unit distance

6b. It is the spring rate measured at the wheel. It is determined by multiplying the spring rate by the motion ratio

7. The outer wheel steers more than the inner wheel in anti-Ackermann

8. % ackermann = wheelbase/intersection = 2700/4000 = 67.5%

9. Since the kingpin axis meets the surface after the wheel center line, the directional control will be poor and unstable.

10. The Revoknuckle geometry effectively reduces the kingpin lateral offset and scrub radius, thereby reducing torque steering.
