    Abstract: An upper portion of a damper connected at its lower end to a lower arm of a suspension is accommodated within a side frame having a closed section. An upper spring seat, which is a mounting portion for the damper, is fixed to a lower surface of the side frame by a bolt. Thus, the support rigidity of the damper is enhanced, whereby the responsiveness of the damper to a load input from the lower arm is improved. Moreover, since the upper portion of the damper is accommodated within the side frame, an internal space in the side frame can be utilized for disposition of the damper. In addition, it is unnecessary to arrange the side frame and the damper side-by-side in a lateral direction of the vehicle body, and hence it is easy to ensure a space for disposition of the suspension.

  • Patent number: 7077248
    Abstract: Suspension strut unit comprising a connector bearing for piston rod of the suspension strut unit, a spring plate for a vehicle spring, and a first has a bearing with a bearing input part on the spring plate side and a bearing output part on the connector bearing side, which bearing allows relative rotational movement between the vehicle spring and the connector bearing of the piston rod. After the piston rod has traveled inward a certain distance, the cylinder is supported against the connector bearing by way of a stop buffer. A second bearing allows relative rotational movement between the connector bearing and the cylinder when the stop buffer is active; the second bearing is located functionally between the stop buffer and the connector bearing, and a functional separation is present between the bearing input part for the spring plate and the second bearing.

  • Patent number: 7066456
    Abstract: An upper portion of a rod protruding from an upper end of a hydraulic cylinder of a hydraulic shock absorber, which suspends a wheel from a vehicle body, is inserted from below into a mounting hole in an upper wall of a wheel house, and with a lower portion and an upper portion of the mounting hole being held by a lower damper mount bushing and an upper damper mount portion, respectively, a nut is then screwed on the upper portion of the rod to thereby fasten the rod to the upper wall of the wheel house. A temporarily fastening locking portion formed integrally with the lower damper mount bushing and fixed to the rod is brought into engagement with the mounting hole in the wheel house to prevent the hydraulic shock absorber from falling away from the wheel house during installation.

  • Patent number: 7032896
    Abstract: Piston-cylinder assembly, comprising a container tube, in which a piston rod is guided with freedom of axial movement, which rod is at least partially covered by a sheath tube with at least one elastic fold, where a resilient stop pad is provided concentrically to the piston rod, the end of which pad comes to rest against an end cap during the inward travel of the piston rod, which end cap rests against the container tube in the fully assembled piston rod assembly. The stop pad, the sheath tube, and the end cap form a preassembled unit which is independent of the piston rod assembly, the end cap being pressed onto the container tube by the resilient stop pad during the inward travel of the piston rod into the container tube.

  • Patent number: 6969053
    Abstract: The present invention provides a strut mount comprising an inner member (12) to which an upper extremity of a rod of a buffer is fixed, an outer member (14) attached to a vehicle while surrounding an outer circumference of the inner member, and an elastomer (16) interposed between both members to dampen vibration, wherein an attachment piece (28) of an outer fitting (14) and an attachment plate (2) of the vehicle body are curved in the form of a sphere to raise rigidity and improve vehicle running stability. Besides, a non-fastening surface portion (36) is provided by being lowered via a different level portion (34) around a bolt fastening surface portion (30) of the attachment piece (28), preventing rubber burr from being produced on the fastening surface. Furthermore, by the use of a caulking nut (52) stuck to the underside of the attachment piece (28), the weight of the products can be reduced, and cost reduction is accomplished by laborsaving during operations.
