Abstract
A traction assist system for a vehicle having a tandem-axle system includes a drive axle and a non-drive axle attached to a suspension beam on opposite sides of a pivot about which the suspension beam is rotatable. A device selectively applies a force to the suspension beam on the side of the pivot at which the drive axle is attached, such that the suspension beam tends to rotate to provide a downward force on the drive axle. The device can also apply the downward force directly to the drive axle.
