  • Patent number: 4722548
    Abstract: A vehicle suspension system in which a computer controls damping and spring forces to optimize ride and handling characteristics under a wide range of driving conditions. A combined shock absorber/air spring unit is connected between the wheel and frame of a vehicle. The shock absorber includes a hydraulic sensor which provides signals to the computer which are representative of the position of the piston within the shock absorber. The computer utilizes these signals to control compression and rebound hydraulic pressure regulators to produce preprogrammed compression and rebound damping forces that will yield the desired ride and handling. The air spring may be connected in series with the shock absorber for compression and rebound along the same axis. Pressure sensors and air pressure inlet and outlet valves are connected to the computer for adjusting the pressure within the air spring to provide the desired spring rate.

  • Patent number: 4722547
    Abstract: An ultra-sonic senor system suitable for monitoring movement of a vehicle, relative to the horizontal employs two or more coordinated ultra-sonic sensors. The sensors may be mounted at opposite ends or on opposite sides of the vehicle, depending on whether pitch or roll respectively is to be monitored. Each sensor broadcasts ultra-sonic waves and receives ultra-sonic waves reflected by the road surface. The transmission time is known; the reception time is measured upon detection of the peak of the reflected waves. The difference between the two above times yields the distance between the vehicle and the road. The difference between the distances measured by two sensor yields the inclination of the vehicle relative to the horizontal plane.

  • Patent number: 4718509
    Abstract: Multi-axle vehicles with individual wheel drives are, for the purpose of improving ground clearance, also equipped with drive trains split in two arrayed in proximity of the wheels, in which distribution drives drive the wheels via articulated shafts. In order that these articulated shafts, despite the short distance between the distribution drive and the wheel hub, do not become so short that either the angle or excursion is very limited, or that the articulation must be stressed unfavorably, and to permit larger spring paths for the wheels, the articulations were integrated into the housings of the distribution and/or wheel hub drives to the extent that the center of the articulation comes to lie immediately at or even behind the intersection of the articulated shaft with the drive train and below the output bearing. The latter receives therto a specially large diameter and short construction length.
