-1 To ensure and maintain the largest possible support surface on the ground (contact point of wheels on ground): energy transmission.
-2 To attenuate, for the chassis-cab unit, brutal variations in the position of the mechanical components due to driving on the road: comfort.

The roles of the suspension system
Technology
Traditional spring leaves are gradually replaced with parabolic spring leaves.
Suspension with parabolic springs
Advantages : Excellent load stability Excellent freight protection conditions Comfort for the driver High resistance to flexion due to braking and starting Significant decrease in dry friction between the leaves Weight is significantly reduced Suspension much less noisy
Suspension with parabolic springs
Suspension systems on Dump TruckSeveral combinations depending on use. Front: 3-leaf parabolic; 8-leaf semi-elliptic Rear :-cross-bar suspension ; -3-leaf parabolic - 7 to 11-leaf semi- elliptic; 2-spring air on 4 x 2 tractors
