Abstract

Devices to shift the stops (8) of rail vehicle bodies or coaches with bogies on curves and rail vehicle body with bogies. The devices are provided in an interior cavity of the frame of the bogies whose lateral edges each have a separate stop (9, 10) and that houses a lower projecting part (4) of the body. In one embodiment, on the front edge of the interior cavity of the frame (1) of the bogie, there is a pair of joints (11) from each of which a rod (5, 6) leads backwards and each of these is joined to a separate slider (7) by means of joints. The sliders (7) are able to move on guides located on the respective lateral surfaces of the lower projecting part (4) of the body, and the sliders (7) are wedge shaped with a guide located on their surface in the form of an inclined plane. The stops (8) of the body are coupled, at their respective inside surfaces, to the guides located on the respective sliders (7); the stops (8) of the body are joined together by transversal connection means (15).

Dependent claims

Device to shift body stops (8) of rail vehicle bodies with bogies on curves, in which a bogie frame (1) bounds an interior cavity whose lateral edges each has a stop (9, 10) and that houses a lower projecting part (4) of the body, such that there are clearances between the lateral edges of the frame (1) of the bogie and corresponding lateral edges of the lower projecting part (4) of the body,

characterized in that the device comprises a pair of first joints (11) arranged symmetrically with respect to a longitudinal axle of the bogie and located on a front edge of an interior cavity of the bogie frame (1), a rod (5, 6) leading backward from a corresponding joint of the pair of first joints, the other end of each rod (5, 6) joined to a slider (7) by means of a second joint, each second joint located on an end of each of the sliders (7),
where the sliders (7) are able to move on guides located on the respective lateral edges of the lower projecting part (4) of the body,
and the sliders (7) are wedge-shaped with a guide located on an outside surface of each slider (7) in the form of an inclined plane,
and in that the body stops (8) of the body are coupled, on respective inside surfaces of the body stops (8), to the guides located on the inclined planes corresponding to the outside surfaces of the respective sliders (7), where the inside surfaces of the body stops (8) have the same inclination as the inclined planes of the sliders (7), and the body stops (8) are joined together by guided transversal connection means (15) such that transversal connection means (15) prevent longitudinal movement of the body stops (8) with respect to the lower projecting part (4) of the body.
