Embodiment Construction

[0023] The figure illustrates the mechanism for operating the front compartment in the body of a railway vehicle, wherein the outlines of the body of the vehicle, the vehicle chassis and the couplers supported by the chassis are schematically indicated in dashed-dotted lines in place.

[0024] Refer to Figure 1 to Figure 4 , an embodiment of the hatch door operating mechanism 1 according to the present invention will be described. When the front cabin is opened, the door operating mechanism 1 is arranged to move into the vehicle body under the guidance of the cantilever beam 2 . The beam 2 is mounted to the vehicle chassis 3 only at the inner end by connecting means designed and adapted to cooperate with the subject vehicle chassis. In the illustrated embodiment, the connection means comprise a transverse box or beam 4 having legs 5 and 6 projecting upwardly from its ends, the legs being arranged in a coupler 7 extending from the chassis Each side is bolted to the vehicle c...

Abstract

The invention relates to a mechanism operative for opening and closure of a front hatch which is retractable into the body of a railway vehicle, whereby in a closed position a coupler which is supported from the vehicle's chassis is covered behind the front hatch and which coupler upon opening of the front hatch is uncovered in order to admit coupling to a connecting railway vehicle, said front hatch comprising at least two separable sections (15, 16; 115, 116) that are pivotally supported on a cantilever beam (2; 102) which extends freely from the vehicle's chassis. In a separated mode, the hatch sections are retractable inside the body in a linear motion which is guided along the cantilever beam (2; 102).

Description

technical field [0001] The present invention relates to a mechanism designed to open / close a front cabin which can be retracted into the main body of a railway vehicle. The couplers supported by the vehicle chassis are concealed behind the bonnet in the closed position, and when the bonnet is opened, the couplers are exposed to allow connection with the railway vehicle to be connected. Background technique [0002] Rail vehicles, such as electric railroad trains and diesel locomotives designed to be less aerodynamic, typically have a body with a streamlined head extending into a constricted, streamlined shape around a coupler mechanism supported by the vehicle chassis. The coupler referred to includes a coupler head provided at the front end of the drawbar and used for detachable connection with a corresponding coupler head on the vehicle to be connected. In couplers designed to connect automatically, the coupler head is connected to a hydropneumatically operated structure ...
