摘要： Load-supporting wheels are rotatably supported by independent axle means for each wheel carried on a substantially horizontal arm pivotally secured to the vehicle body. A spring and shock absorber are mounted to act along the same line or along parallel lines of action on a telescoping unit having one end pivotally connected to the horizontal arm and the other end adjustably connected to the body. Motor driven means have one end secured to the body and have another end connected to the unit and are adapted for inclining the unit more or less. A sensor on the horizontal arm is connected to the motor to drive it in one direction or the other according to the inclination of the horizontal arm as the vehicle load is increased or lightened. When the arm has been restored to its normal horizontal position, normal clearance between body and road is restored, and the suspension parameters are matched to the existing load.
