Abstract
A vertical position compensating device for a vehicle, a vehicle using the device, and a method for controlling the vertical position of a vehicle. The vehicle has a wheel set mounted on a chassis by a primary suspension system and a body mounted on the chassis through a secondary suspension system. The device is mounted on the body. As the vehicle is loaded or unloaded the device moves vertically with the body and also moves relative to the body in proportion to the deflection of the primary suspension system. The total motion of the device is used to adjust the vertical position of the body through the secondary suspension in a direction opposite to the deflection of the body to maintain the position of the body constant relative to a datum line.
