Abstract: A strut bearing unit for a motor vehicle includes a lower cup for supporting a suspension spring, an upper cup for coupling with a top mount which provides a connection to a chassis of the motor vehicle, and a bearing interposed between the upper cup and the lower cup. The upper cup has an inner cylindrical surface and a first set of protruding ribs formed on the inner cylindrical surface for providing a connection between the top mount and the upper cup. The first set of protruding ribs extends axially and is circumferentially distributed around the inner cylindrical surface. Each rib of the first set of protruding ribs has a first axial portion and a second axial portion, the first axial portion and the second axial portion having different thicknesses in the radial direction.

Abstract: A suspension bearing unit includes a lower support cap, an upper bearing cap, at least one bearing disposed between the lower support cap and the upper bearing cap, and at least one gasket overmolded to the upper bearing cap and having a sealing portion extending toward the lower support cap and forming a seal with a portion of the lower support cap. The upper bearing cap includes an external skirt radially surrounding the at least one gasket. Also a method of forming the unit.

Abstract: A suspension bearing unit includes a lower support cap, an upper bearing cap having an axial skirt, and at least one bearing disposed radially between the lower support cap and the upper bearing cap. At least one gasket is at least partially disposed in a space radially between the axial skirt and the at least one bearing and secured to the upper bearing cap or to the lower support cap. The gasket includes a sealing portion, and the sealing portion has at least one recess which may contain a lubricant. When the gasket is secured to the upper bearing cap, the sealing portion seals against a portion of the lower support cap, and when the gasket is secured to the lower support cap the sealing portion seals against a portion of the upper bearing cap.

Abstract: A suspension thrust bearing device provides a lower support cap, an upper bearing cap and at least one bearing arranged between the caps. The lower support cap includes a rigid main body in contact with the bearing, and a flexible vibration damping seat delimiting a bearing surface for the upper end of a suspension ring. The vibration damping seat of the lower support cap is secured to the main body and is provided with at least one retaining hook extending at least in the radial direction and axially offset with respect to the bearing surface on the side opposite to the bearing.

Abstract: A suspension thrust bearing device for use with a suspension spring in an automotive suspension strut of a vehicle. The device provides a bearing having upper and lower annular bearing members in relative rotation, and a damping element made of resilient material and interposed between the lower annular bearing member and the suspension spring. The damping element including at least one deflecting flange for reducing any ingress of water and other pollutants between the upper and lower annular bearing members. The damping element is provided with an annular groove open axially towards the suspension spring, the annular groove radially defining a spring support surface on an inner side, and the deflecting flange on an outer side. The deflecting flange has a frustoconical shape directed axially towards the suspension spring.
