摘要： A suspension thrust bearing device for use with a suspension spring in an automotive suspension strut of a vehicle includes a bearing having an upper annular bearing member and a lower annular bearing member configured for relative rotation. The lower annular bearing member includes a radial body and a damper having a radial portion made of resilient material overmolded to a lower side of the radial body. The damper radial portion has a lower support surface configured to axially support an end coil of the suspension spring, and the damper radial portion has a material hardness of 50 to 85 Shore A and an axial thickness of 2 to 10 mm.

摘要： A suspension thrust bearing device for use with a suspension spring in an automotive suspension strut, and having a bearing with an upper annular part and a lower annular part. The lower annular part includes an axial hub and an outwardly projected radial flange extending from the axial hub, and the lower part has an exterior support surface that axially supports an upper end of a suspension spring by the intermediate of a damping device. The damping device provides an axial portion secured to an axial hub, and a radial portion secured to a radial flange. The axial hub of the lower annular part has a plurality of radially through recesses that are axially open on an axial lower end of the axial hub. The axial portion of the damping device includes a plurality of pins that radially inwardly protrude from the axial portion.

摘要： A suspension thrust bearing device for use with a suspension spring in an automotive suspension strut of a vehicle. The device includes an upper annular bearing member and a lower annular bearing member in relative rotation. The lower annular bearing member having a body provided with an embedded stiffening insert. The device further provides a damping element made of resilient material and interposed between the lower annular bearing member and the suspension spring. A radial flange of the damping element prevents separation from the lower side of the radial flange of the lower cap.

摘要： A suspension thrust bearing device for use with a suspension spring in an automotive suspension strut of a vehicle. The device includes a bearing having upper and lower annular bearing members in relative rotation, the lower annular bearing member, and a damping element. An axial stiffening insert in a hub of lower annular bearing member provides a lower end curved towards the interior of the device. Lower annular bearing member has at least one slender groove opening radially outwards and having a bottom end opening axially downwards, the damping element providing a portion fitted within the slender groove.

摘要： A suspension thrust bearing provides a bearing with annular upper part and annular lower part. The lower part provides an axial hub, an outwardly projected radial flange extending from the axial hub, and a curved connecting portion between the axial hub and radial flange. The lower part provides an exterior support surface that axially supports an upper end of a suspension spring by a damping device made from resilient material. The exterior support surface provides at least one longitudinal groove, the damping device including an interior surface contacting the exterior support surface and including a complementary shape to mate with the groove. The groove extends along the connecting portion, disposed in a recessed portion between two longitudinal side walls, a first groove end on or directed towards the hub, and a second groove end on or directed towards the flange, the second groove end being a transverse wall.
