Challenge 9
- If there were no bushings at all in a suspension system, there would still be compliance present but this will be minimal and negligible. This comes from the various joints, for instance threaded joints, spherical joints, rolling joints and so on.
- Understeer effect under lateral load (cornering). A toe-out situation under longitudanal load (braking) which can give an oversteer effect.
- Since the lateral force acts at the contact patch of the tire with the road which is at the ground level below all the suspension linkage mounting points, it causes the top of the wheel to lean away from the turn centre yielding positive camber.
- Yes, we can. Because if the magnitudes of aligning torque in the rear are greater than that in the front axles, a net oversteer effect is produced since aligning torque compliance always causes an understeer effect in the front and oversteer effect in the rear. By having less compliant steering linkages provided that the rack is placed behind wheel centre, the understeer effect produced can be dampened thus yielding a net oversteer offect. Similarly, a converse setting on the toe link can be made to produce a greater oversteer effect yielding net oversteer.
