  • Patent number: 10094440
    Abstract: The invention concerns a suspension thrust bearing for use with a suspension spring in an automotive suspension strut. The suspension thrust bearing provides a bearing with an annular upper part and a annular lower part in relative rotation one to the other, a lower support surface being provided by the lower part that axially supports an upper end of a suspension spring by the intermediate of a damping device made from resilient material. The resilient material of the damping device is molten in its preformed state with gas. After being molded, the molten material of the damping device provides an outer skinny layer and an inner foam body, the density of the outer skinny layer being strictly greater than the density of the inner foam body.

  • Patent number: 9950582
    Abstract: A suspension stop device provides an upper contact cap, a lower support cap and at least one bearing arranged between the caps. The upper contact cap provides a centering portion for a damper pad, inside which the pad, which is external to the device, is intended to be mounted. The centering portion extends axially inside a bore in the lower support cap.

  • Patent number: 9925839
    Abstract: A suspension bump stop device that provides an upper bearing cap that contacts an upper bearing seat outside of the device, and a lower support cap and at least one bearing arranged between the caps. The upper bearing cap provides a latching means that cooperates with the upper bearing seat to axial secure the bearing seat.

  • Patent number: 9545830
    Abstract: A suspension bearing device, comprising: a bearing, a lower cup and an upper cup centered on a central axis. The lower cup having a body including a tubular axial portion and an annular outward radial portion. The lower cup is provided with a damper pad including: an inner portion disposed against the annular outward radial portion of the body; an outer portion for bearing a suspension spring; and an annular recess for receiving a creep of material of the damper pad when the outer portion is constrained by the suspension spring. The suspension bearing device can be integrated into a motor vehicle. A method for manufacturing such a suspension bearing device.
