Abstract

An enclosure system attachable to a railway vehicle to protect automobiles in the event of a collision. The enclosure system having an enclosure panel that is actuatable between a deployed configuration and a stowed configuration. A breakaway mechanism configured to allow certain components of enclosure system to release from the railway vehicle in the event of a collision with another railway vehicle to ensure the anticlimbers engage between the railway vehicles to prevent override. The enclosure system having a coupler centering assembly for maintaining a coupler in a forward position when the enclosure is in the deployed configuration.

Claims (50)

1 . A railway vehicle enclosure apparatus, comprising:

an enclosure panel;

one or more actuation systems, each comprising an actuating cylinder adapted to actuate the enclosure panel between a stowed configuration and a deployed configuration; and

a breakaway system engaging lateral sides of the enclosure panel when in the deployed configuration, the breakaway system comprising:

at least one breakaway panel abutting the lateral sides of the enclosure panel at a first end and configured to detach from the railway vehicle enclosure apparatus upon a force being exerted on the enclosure panel; and

at least one breakaway block each having a guide slot,

wherein the guide slot and the at least one breakaway block transiently maintain a position of the at least one breakaway panel.

2 . The railway vehicle enclosure apparatus of claim 1 , wherein the actuating cylinder is connected to a railway vehicle at a first end, and wherein the one or more actuation systems each further comprise:

a linkage drive crank connected to the actuating cylinder at a second end; and

a linkage arm coupled to the linkage drive crank at a first end and the enclosure panel at a second end.

3 . The railway vehicle enclosure apparatus of claim 2 , wherein actuation of the actuating cylinder drives rotation of the linkage drive crank, thereby rotating the linkage arm about the first end of the linkage arm and transitioning the enclosure panel between the deployed configuration and the stowed configuration.

4 . The railway vehicle enclosure apparatus of claim 3 , further comprising:

a biasing member coupled to the railway vehicle and the linkage drive crank, the biasing member biasing the enclosure panel towards the stowed configuration.

5 . The railway vehicle enclosure apparatus of claim 4 , further comprising:

a padding disposed on an internal side of the enclosure panel and configured to prevent longitudinal and lateral movement of the enclosure panel when in the stowed configuration.

6 . The railway vehicle enclosure apparatus of claim 1 , wherein the breakaway system further comprises:

at least one shear block engaging a second end of the at least one breakaway panel via a connection block, each shear block comprising:

a stationary block having a stationary slanted portion abutting the connection block; and

a set screw configured to couple the connection block to the shear block.

7 . The railway vehicle enclosure apparatus of claim 6 , wherein one or more of the guide slot and the stationary slanted portion are configured to guide the at least one breakaway panel outwardly from the railway vehicle enclosure apparatus when the force is exerted on the enclosure panel.

8 . The railway vehicle enclosure apparatus of claim 1 , further comprising:

a coupler centering assembly disposed on the enclosure panel and configured to maintain a coupler of a railway vehicle in a forward direction when the enclosure panel is in the deployed configuration.

9 . The railway vehicle enclosure apparatus of claim 1 , further comprising a linkage mount having a receiving hole, and wherein one or more linkage drive cranks of the one or more actuation systems are coupled to one or more linkage arms via an extending member, the extending member being received within and supported by the receiving hole of the linkage mount.

10 . An enclosure system for a railway vehicle, the enclosure system comprising:

an enclosure panel; and

a breakaway system engaging lateral sides of the enclosure panel, the breakaway system comprising:

at least one breakaway panel abutting the lateral sides of the enclosure panel at a first end;

one or more breakaway blocks transiently maintaining a position of the at least one breakaway panel; and

one or more shear blocks engaging the at least one breakaway panel at a second end,

wherein the one or more breakaway blocks and the one or more shear blocks are configured to guide the at least one breakaway panel upon a force being exerted on the enclosure panel.

11 . The enclosure system of claim 10 , wherein each of the one or more breakaway blocks comprises a guide slot engaging the at least one breakaway panel.

12 . The enclosure system of claim 11 , wherein each of the one or more shear blocks comprises:

a connection block being partially received by the at least one breakaway panel at the second end;

a stationary block having a stationary slanted portion abutting the connection block; and

a set screw coupling the connection block to the stationary block at the stationary slanted portion.

13 . The enclosure system of claim 12 , wherein the set screw comprises a shear pin disposed at the abutment of the stationary slanted portion and the connection block, the shear pin configured to shear upon the force being exerted on the enclosure panel.

14 . The enclosure system of claim 13 , wherein the enclosure panel comprises a groove at the lateral sides having one or more connective extensions disposed therein, and wherein the at least one breakaway panel comprises a ridge configured to receive the one or more connective extensions and be received within the groove.

15 . The enclosure system of claim 14 , further comprising at least one linkage mount configured to attach to the railway vehicle, wherein the one or more breakaway blocks are coupled to the at least one linkage mount.

16 . An enclosure system for a railway vehicle, the enclosure system comprising:

an enclosure panel;

one or more actuation mechanisms coupled to the enclosure panel, the one or more actuation mechanisms comprising:

one or more linkage arms coupled to the enclosure panel;

one or more linkage drive cranks coupled to the one or more linkage arms; and

one or more actuating cylinders configured to drive rotation of the one or more linkage drive cranks,

wherein rotation of the one or more linkage drive cranks actuates the one or more linkage arms, thereby actuating the enclosure panel between a stowed configuration and a deployed configuration; and

a coupler centering assembly, comprising at least one horizontal corral and at least one vertical corral configured to bias a coupler of the railway vehicle towards and through the coupler centering assembly and maintain the coupler therethrough when the enclosure panel is in the deployed configuration.

17 . The enclosure system of claim 16 , further comprising a linkage mount having a receiving hole, and wherein the one or more linkage drive cranks are coupled to at least one of the one or more linkage arms via an extending member, the extending member being received within and supported by the receiving hole of the linkage mount.

18 . The enclosure system of claim 16 , wherein while the enclosure panel is in the stowed configuration, the coupler is capable of attaching to another coupler of a separate railway vehicle.

19 . The enclosure system of claim 16 , further comprising a biasing member operatively connected to the one or more linkage drive cranks and biasing the enclosure panel towards the stowed configuration.

20 . The enclosure system of claim 16 , further comprising a receiving mechanism disposed on the railway vehicle and a pin disposed on the enclosure panel, the receiving mechanism configured to receive the pin and maintain the enclosure panel in the stowed configuration.
