Abstract
A truck or double bogie having forward and rear elemental bogies (1, 2). The vehicle body is carried at the middle by a spanner bolster or two longitudinal coupling beams (8, 9) which are supported, at each end and on each elemental bogie, on the ends of a transverse swingle bar (12, 13), resilient blocks (15) being inserted between the swingle bar and the bolsters (3, 4) of the elemental bogie. The buffer and coupling bodies (34) are arranged at the end of a guide shaft (32) which is freely articulated on a vertical central pivot (30) rigidly fixed to the vehicle body and on the vertical pivot (5) of the forward elemental bogie (1). The device is intended for use with bogies for railroad vehicles intended to run on poor quality track.
Claims4
Truck assembly for railroad vehicle body, comprising
- (a) two component bogies forming each truck and connected by a spanner bolster mounted on said bogies by pivots, including a forward bogie (1) arranged adjacent each end of said vehicle body, and a rear bogie (2) arranged centrally of said vehicle body;
- (b) said body of said vehicle being supported centrally of said spanner bolster between said bogies;
- (c) said spanner bolster being formed of spaced beams, ends of said beams (8, 9) being pivotally supported, with respect to each component bogie (1, 2), on a transverse swingle bar (12, 13) articulated on the pivot of each said bogie;
- (d) transversely deformable resilient blocks (15) being arranged between each end of said swingle bars (12, 13) and a bolster (3, 4) carrying said pivot of said bogie, whereby, under load conditions, said swingle bar transmits only a reduced load to said pivot;
- and
- (e) a pole (32) hinged to both a vertical pivot (30) solid with said body centrally of the truck assembly, and to the vertical pivot (5) of said forward composite bogie, said pole having a forward end for the attachment of a coupler.
