Contextualization
WHAT IS CAMBAGE?
A mechanical phenomenon, the kinematics of the suspension, which allows changing the characteristics of the tire-ground contact point, via tire deformation and providing a lateral force that can optimize the vehicle's performance in curves.
VEHICLE PHYSICAL BEHAVIOR
The vehicle can have 3 characteristics when making a turn. Under-steering, when the front wheels slip more than the rear wheels, causing the steering angle to increase as the turn progresses. On the other hand, there is oversteering, which occurs when the rear wheels slip more than the front wheels and the steering wheel angle needs to decrease as the corner progresses. Finally, there is the neutral condition, where there is identical slip between the front and rear wheels. The following figures illustrate the understeer, neutral and oversteer behavior, respectively.
Proposal Solution
LOWER ARM LENGTH VARIATION
BENEFITS:
Possibility of dynamic adjustment, with the vehicle in operation;
Greater accuracy in the degree of camber;
Possibility of using mechanical or electronic drive;
It does not change the damper fastening geometry and the distance between springs.
DISADVANTAGES:
Limited by internal wheel geometry;
Greater effort on the stub axle;
Being located at a low height in relation to the ground, which can lead to damage from holes or ditches;
Increased unsprung mass of the vehicle.
