    摘要： A railcar adapter for connecting a railcar body to a bearing is provided. The railcar adapter includes an adapter body having two lateral channels each delimited by a pair of opposed lugs adapted to cooperate with the railcar body, an inner surface acting as a bearing seat for the bearing and an outer surface in radial contact with the railcar body. The inner surface includes at least one central groove located on a first axis of symmetry of the railcar adapter emerging in each lateral channel. The inner surface further provides a second central groove located on a second symmetry axis of the railcar adapter, perpendicular to the first symmetry axis.

    摘要： An axle bearing device includes an inner ring fixed to an axle of a railway vehicle, an outer ring fixed to a journal box of the railway vehicle, and double row tapered rollers arranged between raceway surfaces of the inner ring and raceway surfaces of the outer ring. An opening portion between the inner ring and the outer ring is sealed by a labyrinth seal including at least one axial labyrinth extending in an axial direction and at least one radial labyrinth extending in a radial direction. At least one of the at least one axial labyrinth and the at least one radial labyrinth which form the labyrinth seal is formed between an outer-ring-side sealing member mounted to the outer ring and the inner ring or between the outer-ring-side sealing member mounted to the outer ring and an inner-ring-side sealing member mounted to the inner ring.

    摘要： A side frame key assembly for a roller bearing unit mounted for relative vertical movement in a pedestal-type side frame comprises a one-piece angular key structure overlying a horizontal base portion of the frame and movably mounted in the key opening of the side frame and an extension spring underlying the horizontal base portion and releasably engaging spaced attachment portions of the key structure to complete a tie loop interlocking with the horizontal base portion to retain the key structure in position to react directly against the side frame when the roller bearing unit applies load force to the key structure.

    摘要： The invention relates to a railroad car truck in which the side frames are carried inboard of the wheels on supports that are stationary relative to the side frames. The side frames are provided with spring seats that are substantially aligned with the planes of the wheels on either side of the truck and support through spring groups a bolster of special design that supports the weight of the car body at two points on either side of the bolster, which points are aligned with the respective spring groups. The truck bolster is pivoted to the car body bolster by the usual kingpin, but the coupling arrangement involved is such that none of the body weight is supported at the customary center plate area of the bolster, which area is eliminated in the present truck. The truck bolster at its midportion includes a socket structure into which a projection of the body bolster fits for applying longitudinally and laterally acting forces to the bolster from which they are transferred to the side frames through suitable engaging surfaces. In one form of the invention, the side frames are mounted on tubular housings for the axles, which housings are journalled relative to the wheels through special roller bearing or friction bearing arrangements that are herein disclosed. In another form of the invention, the side frames are mounted directly on the axles, which are stationary relative thereto, and which have the truck wheels journalled on the respective ends through a special friction type bearing arrangement, with the result that the truck wheels rotate independently of each other.
