End guide system and method for a truck assembly of a rail vehicle
A truck assembly of a rail vehicle includes a side frame including a spring seat below an opening. The spring seat includes a locating pocket. An end guide system is coupled to the side frame. The end guide system includes a central base configured to be received and retained by the locating pocket. At least one end guide extends outwardly and upwardly from the central base.
1. A truck assembly of a rail vehicle, the truck assembly comprising:
a side frame including a spring seat below an opening, wherein the spring seat includes ramps extending upwardly from an upper surface of the spring seat at opposite ends, wherein each of the ramps includes a channel, wherein tabs extend upwardly from the spring seat, wherein an internal rim extends upwardly from the spring seat, and wherein a locating pocket is defined between the upper surface of the spring seat, the ramps, and the internal rim; and
an end guide system removably coupled to the side frame, wherein the end guide system comprises:
a central base configured to be received and retained by the locating pocket; and
at least one end guide extending outwardly and upwardly from the central base.
2. The truck assembly of claim 1 , wherein the at least one end guide extends outwardly and upwardly from the central base at an angle in relation to the central base, and wherein the angle is between 10-20 degrees.
3. The truck assembly of claim 1 , wherein the at least one guide comprises:
a first end guide extending from a first end of the central base; and
a second end guide extending from a second end of the central base, wherein the second end is opposite from the first end.
4. The truck assembly of claim 3 , wherein the central base, the first end guide, and the second end are integrally molded and formed as a single piece.
5. The truck assembly of claim 1 , wherein the central base is longitudinally and laterally constrained within the locating pocket.
6. The truck assembly of claim 1 , further comprising one or more springs that exert a downward force into the central base of the end guide system, wherein at least a portion of the central base is sandwiched between the one or more springs and the spring seat of the side frame.
7. The truck assembly of claim 1 , wherein the spring seat further comprises an additional locating pocket.
8. The truck assembly of claim 7 , wherein the locating pocket and the additional locating pocket are mirror image structures of one another.
9. An end guide system configured to removably secure to a side frame of a truck assembly of a rail vehicle, the end guide system comprising:
a central base configured to be received and retained by a locating pocket of the side frame, wherein the side frame comprises a spring seat that includes ramps extending upwardly from an upper surface of the spring seat at opposite ends, wherein each of the ramps includes a channel, wherein tabs extend upwardly from the spring seat, wherein an internal rim extends upwardly from the spring seat, and wherein the locating pocket is defined between the upper surface of the spring seat, the ramps, and the internal rim; and
at least one end guide extending outwardly and upwardly from the central base.
10. The end guide system of claim 9 , wherein the at least one end guide extends outwardly and upwardly from the central base at an angle in relation to the central base, and wherein the angle is between 10-20 degrees.
11. The end guide system of claim 9 , wherein the at least one guide comprises:
a first end guide extending from a first end of the central base; and
a second guide extending from a second end of the central base, wherein the second end is opposite from the first end.
12. The end guide system of claim 11 , wherein the central base, the first end guide, and the second end are integrally molded and formed as a single piece.
13. The end guide system of claim 9 , wherein the central base is configured to be longitudinally and laterally constrained within the locating pocket.
14. The end guide system of claim 9 , wherein one or more springs exert a downward force into the central base of the end guide system, wherein at least a portion of the central base is configured to be sandwiched between the one or more springs and the spring seat of the side frame.
15. A method for a truck assembly of a rail vehicle, the method comprising:
removably coupling an end guide system to a side frame, wherein the side frame includes a spring seat below an opening, and wherein the spring seat includes ramps extending upwardly from an upper surface of the spring seat at opposite ends, wherein each of the ramps includes a channel, wherein a plurality of tabs extend upwardly from the spring seat, wherein an internal rim extends upwardly from the spring seat, and wherein a locating pocket is defined between the upper surface of the spring seat, the ramps, and the internal rim.
16. The method of claim 15 , wherein said removably coupling comprises receiving and retaining a central base of the end guide system by the locating pocket, and wherein at least one end guide extends outwardly and upwardly from the central base.
17. The method of claim 16 , further comprising integrally molded and forming the central base and the at least one end guide as a single piece.
18. The method of claim 16 , further comprising longitudinally and laterally constraining the central base within the locating pocket.
19. The method of claim 16 , further comprising sandwiching at least a portion of the central base between one or more springs and the spring seat of the side frame.
20. The method of claim 15 , wherein said removably coupling comprises securing the end guide system to the side frame without fasteners.
