RADIAL SHAFT SEAL ASSEMBLY WITH DEBRIS EXCLUSION MEMBER AND METHOD OF CONSTRUCTION THEREOF
A radial shaft seal assembly (10) for establishing a seal to separate an oil side from an air side of the assembly is provided. The assembly includes a metal case (12) having a cylindrical wall (14) with an annular leg (22) extending radially inwardly from the cylindrical wall. A primary seal lip (28) is operably attached to the metal case. The primary seal lip is configured for running contact with a rotatable shaft member (48) to separate the oil side (O) from the air side (A). A debris exclusion member (30) including an annular retainer (32) with a plurality of elongate bristles (34) fixed thereto is fixed to one of the rotatable shaft member (17) or the metal case, wherein the bristles extend radially free ends (54), with a clearance gap (G) being established between the free ends and the other of the rotatable shaft member and the metal case.
A piston including at least one insert disposed between an inner surface of a ring belt and undercrown surface, and/or between the inner surface of the ring belt and a pin boss, to provide reinforcement to the ring belt is provided. The insert reduces thermal and mechanical distortion of the ring belt, and thus increases the piston ring performance, reduces blow-by, and ultimately improves engine emissions. The insert is formed by an additive machining process, such as direct depositing, laser cladding, laser sintering, arc welding, additive welding, plasma transferred arc spraying, plasma welding, arc welding, selective laser sintering, and high velocity oxygen fuel spraying, plasma spraying. According to one embodiment, an intermediate piece is mechanically attached to the piston, and the insert is applied to the intermediate piece, to provide additional reinforcement.
