AI Technical Summary

Benefits of technology

The patent describes a device for directing wheels on a rail vehicle. The device ensures that the wheel's bearing areas are sufficient to provide support even if the rails or wheels are worn. The device also allows the rail vehicle to travel in both directions, and the device includes a guide arrangement for smooth travel. The device uses a triangular or wedge-shaped wheel urging member to direct the wheels along the rails. The technical effects of this device include improved stability and reliability of the rail vehicle, and smoother and more efficient travel along the rail network.

Problems solved by technology

The possibility exists that excessive wear on the rail and wheel flange could cause a wheel to have insufficient contact with the supporting rail.

Embodiment Construction

[0097]FIGS. 1 and 2 show a rail junction assembly 10 which can be used for directing rail vehicles travelling into the rail junction assembly in the facing direction, i.e. in the direction indicated by the arrow F in FIGS. 1 and 2 or in the trailing direction, i.e. in the directions indicated by the arrows G and H.

[0098]The rail junction assembly 10 comprises a first fixed continuous main rail 12, a second fixed continuous main rail 14, a first fixed switch rail 16 having an end region terminating in close proximity to the first main rail, and a second fixed switch rail 18 having an end region terminating in close proximity to the second fixed main rail 14.

[0099]A first flange receiving passage 17 is defined between the first main rail 12 and a first terminating region 16A of the first switch rail 16. A second flange receiving passage 19 is defined between the second main rail and a second terminating region 18A of the second switch rail 18. The rail junction assembly 10 also includ...

Abstract

A rail junction assembly (10) for directing first and second rail vehicle wheels (42, 44) of a wheel arrangement (40) is disclosed. The rail junction assembly comprises first and second main rails (12, 14) and first and second switch rails (16, 18). A first flange receiving passage (17) is defined between the first switch rail and the first main rail. A second flange receiving passage (19) is defined between the second switch rail and the second main rail. The first flange receiving passage is configured to receive a flange (48) of the first wheel, and the second flange receiving passage is configured to receive a flange (48) of the second wheel. A wheel control arrangement (30) controls the first wheel on the first main rail when the second flange is received in the second flange receiving passage, and controls the second wheel on with the second main rail when the first flange is received in the first flange receiving passage.

Description

TECHNICAL FIELD[0001]This invention relates to rail junction assemblies. This invention relates to methods of directing first and second rail vehicle wheels. This invention also relates to wheel urging members for use with rail junction assemblies. This invention relates to rail switching arrangements. More particularly, but not exclusively, this invention relates to rail junction assemblies having two fixed main rails and two fixed switch rails.BACKGROUND ART[0002]Rail junctions, such as found on railway lines, typically comprise two continuous rails and two switch rails. The switch rails terminate at the junction. A change in direction of a rail mounted vehicle, such as a train, is effected by moving the two switch rails, such that one rail engages the continuous rail of the non-required direction, and the other switch rail moves away from engagement with the continuous rail of the required direction.[0003]An alternative method of directing a rail vehicle uses switch rails fixed i...
