  • Patent number: 8205896
    Abstract: An independent wheel suspension with a rotating steering knuckle which supports itself on a spring carrier is connected with the vehicle frame via a damper. The steering knuckle is connected with the spring carrier via a kingpin, and the wheel suspension has upper and lower transverse links which are positioned at the upper or lower ends of the kingpin. The steering knuckle and the transverse links are pivotally positioned relative to the kingpin and the spring carrier is connected with the kingpin in a rotationally fixed manner. The kingpin connects the spring carrier, the steering knuckle, and the upper end lower transverse links and is a two-piece part which comprises upper and lower parts. Axially, radially and rotationally fixing the upper and the lower parts and the spring carrier is achieved by a combination of the upper and the lower parts with the spring carrier.

  • Patent number: 6296264
    Abstract: The invention relates to a suspension for a single wheel of a motor vehicle. A steering knuckle with wheel hub (1) is attached to a steering knuckle carrier (2) by a steering knuckle pin which is connected by a ball and socket joint (3) on its underside to a suspension arm (4) which is secured to the vehicle frame (6) by a pivot bearing (5). A second suspension arm (7) placed above the first suspension arm (4) connects, by means of a pair of tapered roller bearings, the upper part of the steering knuckle carrier (2) to the vehicle frame (6) through a pivot bearing (9).

  • Patent number: 4394922
    Abstract: A stopper assembly for pharmaceutical containers or the like having a pull ring operable between a position flush with the top face of the stopper and an erect position engageable by the finger of the user for removing the stopper from the container. In acccordance with the preferred embodiment, the stopper and pull ring member are separate elements. The stopper which is preferably made of rubber has an annular groove with a locking shoulder to receive an insert ring of the pull ring member of complemetary shape to retain the two in a locked position. A pull ring is connected to a flange of the insert ring by a flexible hinge. The pull ring normally lies in the plane of the insert ring flange flush with the top face of the stopper and may be easily raised to an erect position to receive a finger of the user to enable removal of the stopper from a container by a pulling action.
