Railcar adapter for connecting a railcar body to a bearing

A railcar adapter for radially connecting a railcar body to a bearing, and comprising an adapter body having:

• two lateral channels each delimited by a pair of opposed lugs and a lateral surface perpendicular to the opposed lugs, lateral channels being adapted to cooperate with the railcar body,
• two frontal surfaces,
• an inner surface acting as a bearing seat for the bearing, and
• an outer surface,
• wherein the railcar adapter also comprises two frontal flanges that inwardly protrude with respect to the inner surface, and that delimit with the inner surface a housing for the bearing, and
• wherein at least one of the flanges is distinct from the adapter body and is mounted to a frontal surface of the body, the at least one flange being connected to a fixing plate that is mounted to the outer surface of the adapter body.

A railcar adapter assembly comprising:

• a railcar adapter,
• a bearing mounted inside the railcar adapter,
• a backing ring adapted to come into axial contact with the bearing at a first side, and
• an end cap assembly adapted to come into axial contact with the bearing at another side, opposite to the first side, the railcar adapter comprising an adapter body having:
• two lateral channels each delimited by a pair of opposed lugs and a lateral surface perpendicular to the opposed lugs, lateral channels being adapted to cooperate with the railcar body,
• two frontal surfaces,
• an inner surface acting as a bearing seat for the bearing, and
• an outer surface,
• wherein the railcar adapter also comprises two frontal flanges that inwardly protrude with respect to the inner surface, and that delimit with the inner surface a housing for the bearing, and wherein at least one of the two frontal flanges is distinct from the adapter body and is mounted to a frontal surface of the body, wherein at least one of the two frontal flanges is provided with a hook that protrudes towards the bearing, the hook being dedicated to cooperate with the bearing.

A railcar axle comprising:

• a railcar adapter assembly including a bearing mounted inside the railcar adapter,
• a backing ring adapted to come into axial contact with the bearing at a first side, and
• an end cap assembly adapted to come into axial contact with the bearing at another side, opposite to the first side,
• a shaft being rotatably mounted about an axis of rotation relative to a railcar adapter, inside the bearing, the shaft comprising a first end mounted radially inside the backing ring and a second end, opposite to the first end, secured to the end cap assembly, the railcar adapter comprising an adapter body having:
• two lateral channels each delimited by a pair of opposed lugs and a lateral surface perpendicular to the opposed Jugs, lateral channels being adapted to cooperate with the railcar body,
• two frontal surfaces,
• an inner surface acting as a bearing seat for the bearing,
• and an outer surface,
• wherein the railcar adapter also comprises two frontal flanges that inwardly protrude with respect to the inner surface, and that delimit with the inner surface a housing for the bearing, and
• wherein at least one of the flanges is distinct from the adapter body and is mounted to a frontal surface of the body.
