An articulated connector for a rail vehicle having a plurality of rail car bodies including a first and a second rail car body supported on a bolster of a Jacobs bogie, the articulated connector comprising:
- a spherical joint mechanism having a first joint with a spherical bearing articulably connecting the first rail car body and the second rail car body to one another, the spherical joint mechanism further having a second spherical joint with a spherical bearing articulably connecting the spherical bearing of the first joint to the bolster of the Jacobs bogie;
- the first joint and the second joint being independently articulable;
- and
- the spherical joint mechanism being disposed on the bolster of the Jacobs bogie;
- the first joint coupling the first and second rail car body and the second joint received within a portion of the Jacobs bogie;
- wherein bearing surfaces of both joints surround a spacer bolt that extends between and interconnects the joints;
- and
- wherein each spherical bearing has a ball segment and a bearing shell surrounding the ball segment, the ball segment and bearing shell each being rotationally symmetrical.
A rail vehicle, comprising:
- a plurality of rail car bodies including a first and a second rail car body;
- a Jacobs bogie having a bolster, the first and second rail car body being supported by the bolster of the Jacobs bogie;
- a spherical joint mechanism connecting the first and second rail car bodies with each other, the spherical joint mechanism being disposed on the bolster, the spherical joint mechanism comprising at least two spherical joints each having a spherical joint bearing, the spherical joints being spaced apart from one another in a direction of a vertical axis of the rail vehicle and the bearing surfaces of both joints surround a spacer bolt that extends between and interconnects the joints;
- wherein each spherical bearing has a ball segment and a bearing shell surrounding the ball segment, the ball segment and bearing shell each being rotationally symmetrical.
