Problems solved by technology

However, when the existing trains go abroad, the gauges of the rails are different between countries, so the trains cannot be used directly, and they need to be unloaded and then loaded on to trains from other countries, which wastes manpower, material resources and time.

Embodiment Construction

[0012] In the figure, the wheel 1 has a small round tread 1-1, a large round tread 1-2, and a rim 1-3.

[0013] The rails of different gauges are symmetrical and have a height difference butt joint. The wide gauge rail 3 is higher than the radius difference between the 1-2 and 1-1 of the wheel tread circle (see image 3 ).

[0014] When the train is running on the standard gauge rail 2, the large circular tread 1-2 of wheel 1 is in contact with the rail (see figure 2 ).

[0015] When the train is changed from the standard gauge rail 2 to the wide gauge rail 3, the small round tread 1-1 of wheel 1 and the large round tread 1-2 are simultaneously pressed on the two rails 3 and 2 (see image 3 ).

[0016] When the train enters the wide gauge rail 3, the small circular tread 1-1 of wheel 1 contacts the rail, and the large circular tread 1-2 plays the role of the wheel flange to guide the train operation (see figure 1 ).

[0017] Note:

[0018] 1. (1524mm-1435mm) / 2=44.5mm, that is, the the...

Abstract

The invention provides a double-tread wheel. A tread of a train wheel is designed to be a step type. Steel rails with different rail gauges are linearly symmetrical, and in abutment joint with each other with altitude differences seamlessly, and the steel rails with wide rail gauges are higher by a circular radius difference than the two treads of the wheel. When a train runs on the steel rails with a standard rail gauge, the large circular tread is in contact with the steel rails. When the train runs on the steel rails with a wide rail gauge, the small circular tread is in contact with the steel rails, and the large circular tread serves as a wheel edge to guide the train to run.

Description

Technical field [0001] The invention relates to a train wheel, specifically a train wheel adapted to double-gauge steel rails. Background technique [0002] In order to deliver goods to most countries in the world quickly and at low cost, direct transnational train transportation is required. With existing trains going abroad, the rail gauges are different from country to country, and the trains cannot be used directly. They need to be unloaded and then loaded on trains from other countries, which wastes manpower, material resources and time. [0003] Judging from the current cross-border railway trade in my country, it mainly trades with the Commonwealth of Independent States (the former Soviet Union) and European Union countries. Most of the European Union countries have the same rail gauge as ours. They are all standard gauges of 1435 mm. ) The national rail gauge is a wide gauge of 1524 mm. As long as our trains can run to the CIS (former Soviet Union) countries, they can run t...
