The seal provides a claw secured by mechanical connection to the upper support cap, a sealing lip extending obliquely from the claw in the direction of the upper bearing cap.
Claims20
A suspension abutment device comprising:
- a lower support cap provided with an annular radial support portion;
- an upper bearing cap provided with an annular radial bearing portion;
- the upper bearing cap having an annular axial external skirt;
- an annular passage being defined between the axial external skirt and the radial support portion;
- at least one bearing disposed between an upper surface of the radial support portion and a lower surface of the radial bearing portion;
- at least one annular seal disposed radially at least in part between the exterior skirt of the upper bearing cap and the bearing;
- and
- wherein the seal comprises an annular claw secured by mechanical connection to an interior axial surface of the axial external skirt of the upper bearing cap and at least one sealing lip extending obliquely inwards and downwards from the claw, in the direction of the radial support portion of a lower bearing cap, in such a manner that a free end of the lip comes into the immediate proximity of a surface of the radial support portion, the seal being formed in one piece.

A suspension abutment device comprising:
- a bearing;
- a lower support cap which defines an annular radial support portion configured to support the bearing thereon;
- an upper bearing cap defining an annular radial bearing portion configured to support the bearing thereon such that the bearing is positioned between the lower support cap and the upper bearing cap, the upper bearing cap having an annular axial external skirt;
- a shock absorber positioned on the lower support cap;
- wherein an annular passage is defined between the axial external skirt of the upper bearing cap and the annular radial support portion of the lower support cap, the annular passage having an external opening located between a distal end of the axial external skirt and a radially extending axial surface formed by both a portion of the shock absorber and a portion of the lower support cap, and on a radially outer surface of the suspension abutment device;
- an annular seal disposed radially at least in part between an exterior skirt of the upper bearing cap and the bearing, the annular seal comprises an annular claw located on an interior axial surface of the axial external skirt of the upper bearing cap, the annular seal further comprising a sealing lip extending obliquely inwards and downwards from the annular claw, in the direction of the annular radial support portion of the lower bearing cap, in such a manner that a free end of the sealing lip comes into the immediate proximity of an axially extending radial surface of the radial support portion, and the external opening.
