Abstract: A railcar adapter for radially connecting a railcar body to a bearing. The railcar adapter includes 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. The railcar adapter also includes two frontal surfaces, an inner surface acting as a bearing seat for the bearing, and an outer surface. The railcar adapter provides 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 at least one of the flanges is distinct from the adapter body and is mounted to a frontal surface of the body.

Abstract: A railcar adapter for radially connecting a railcar body to a bearing, and providing an adapter body. The railcar adapter includes two channel elements having each a pair of opposed lugs and a lateral guiding surface perpendicular to the opposed lugs so as to form lateral channels adapted to cooperate with the railcar body. The lateral channel elements are mounted in transverse grooves provided to transverse surfaces of the adapter body.

Abstract: A railcar adapter for radially connecting a railcar body to a bearing. The railcar adapter includes two lateral channels each delimited by a pair of opposed lugs and a lateral guiding surface perpendicular to the opposed lugs, lateral channels being adapted to cooperate with the railcar body. The lateral guiding surfaces of lateral channels, in cross-section through a plane perpendicular to the axis of rotation of bearing, are curved.

Abstract: An axlebox of railway vehicle bogie comprising a housing, a front cover fixed to a front side of the housing, a rear cover fixed to a rear side of the housing, a cylindrical roller bearing unit, an end cap and a backing ring. A rear chamber and a front chamber on both axial sides of the sealed bearing unit are in fluidic connection through a bypass system.

Abstract: Railcar adapter for connecting a railcar body to a bearing providing an adapter body having two lateral channels each axially delimited by a pair of opposed lugs and a lateral surface perpendicular to the opposed lugs, each lateral channel being adapted to cooperate with the railcar body. The railcar adapter further provides swivelling means allowing swivelling of the railcar adapter relative to the railcar body.

Abstract: A lock that is inserted and fixed in a receiving body of a motor vehicle is disclosed. The lock includes a stator inside which a rotor rotatably moves. The stator is fixed to the receiving body and includes a cover plate of the rotor fixed to the front face of the stator, where the cover plate has an opening for a key. There is also an anti-pull-out mechanism borne by said cover plate and the stator to fix the cover plate to the stator and to retain the rotor axially in the stator. The anti-pull-out mechanism blocks the cover plate axially on the stator by the positioning of the cover plate and its subsequent pivoting on the stator into an assembled position. The anti-pull-out mechanism includes an element for blocking in rotation the cover plate on the stator interposed between the cover plate and the front face of the stator.

Abstract: The present invention relates to a mechanical system with a one-way clutch, for example a pulley for a motor vehicle alternator, comprising a first element and a second element which are able to move one with respect to the other in rotation about a central axis and delimit an annular housing radially to the central axis, a one-way clutch device arranged in the annular housing, and at least one rolling bearing arranged in the annular housing. The mechanical system is characterized in that the rolling bearing comprises at least one pressed ring distinct from the constituent elements of the one-way clutch device. The invention also relates to an alternator comprising such a mechanical system configured as a pulley with a one-way clutch.
