  • Patent number: 8590718
    Abstract: A coupling unit for a semi-permanent connection of two wagons of a rail vehicle, which has a first housing and a second housing, which is pivotably and rotatably coupled to the first housing. A bearing outer ring with a hollow spherical inner bearing surface is fastened to the second housing and is guided in sliding fashion on a bearing inner ring with a spherical outer surface. The bearing inner ring is seated with an inner bore on a shaft fastened to the first housing. The shaft has, on a first end, one or two flattened portions and, on a second end, one or two second flattened portions. At least one clamping piece is provided which bears against one of the flattened portions and an opening region in the first housing, thereby preventing the shaft from rotating.

  • Patent number: 8033748
    Abstract: An arrangement for the articulated connection of wagons of a multiple-element vehicle with the aid of joint having spherical bearing faces, wherein comprising a radial pivoting bearing having an inner ring with a convexly curved spherical bearing face and an outer ring with a concavely curved spherical bearing face, the radial pivoting bearing being installed with a vertical bearing axis Z and the inner ring and the outer ring each being held by one connecting construction, the bearing of asymmetric configuration, the inner ring and the outer ring being arranged offset with respect to one another in the direction of the bearing axis Z, and, that in relation to a center point (M) of the inner ring, the bearing faces are larger in the direction of a negative Z axis extending downwards from the center point along the bearing axis, than the bearing faces in the direction of a positive Z axis extending upwards from the center point along the bearing axis.

  • Patent number: 7832575
    Abstract: An articulated joint coupling (1) for rail vehicles comprises a coupling lug (3), which engages into a coupling fork (4), and a spherical bearing (2) in the coupling lug (3), with the spherical bearing (2) having an inner ring (5) with a convex surface (6) which is pivotably mounted in an outer ring (7) with a concave surface (8), and with the outer ring (7) being fastened in an opening (14) of the coupling lug (3). To fasten the outer ring (7) in the opening (14) of the coupling lug (3), both the outer ring (7) and also the coupling lug (3) have in each case one groove (15, 17), with a clamping ring (18) lying in the groove (17) of the outer ring (7) and simultaneously in the groove (15) of the coupling lug (3).

  • Patent number: 7798345
    Abstract: An articulated coupling for rail vehicles is composed of a fork head having two fork pieces and of a coupling link. The coupling link accommodates a spherical joint which is traversed by a pin secured in the fork head. To fasten the pin in the fork piece, there is provided a wedge which is arranged in the axial direction of the pin and has a concavely curved surface adapted to the cylindrical curvature of the surface of the pin.

  • Publication number: 20060108310
    Abstract: The invention relates to an arrangement for the articulated connection of wagons of a multiple-element vehicle with the aid of a joint having spherical bearing faces. The pivoting connection is distinguished by the fact that the joint is configured as a radial pivoting bearing (1) having an inner ring (2) with a convexly curved spherical bearing face (2.1) and an outer ring (3) with a concavely curved spherical bearing face (3.1), the radial pivoting bearing (1) being installed with a vertical bearing axis (Z) and the inner ring (2) and the outer ring (3) being held by in each case one connecting construction (5, 6).
