A train wheel or rail wheel is a type of wheel specially designed for use on railway tracks. The wheel acts as a rolling component, typically press fitted onto an axle and mounted directly on a railway carriage or locomotive , or indirectly on a bogie (in the UK), also called a truck (in North America).
Without the conical shape, a wheel would tend to continue in a straight path due to the inertia of the rail vehicle, causing the wheelset to move towards the outer rail on the curve. The cone increases the effective diameter of the wheel as it moves towards the outer rail, and since the wheels are mounted rigidly on the axle, the outer wheels ...
An axlebox, also known as a journal box in North America, is the mechanical subassembly on each end of the axles under a railway wagon, coach or locomotive; it contains bearings and thus transfers the wagon, coach or locomotive weight to the wheels and rails; the bearing design is typically oil-bathed plain bearings on older rolling stock, or roller bearings on newer rolling stock.
Allen's elastic rail wagon wheels, designed and manufactured by John Brown & Co in Sheffield. The company John Brown & Co in Sheffield, England, came to an agreement with the inventor on the manufacture of paper wheels in Europe. It installed the necessary machines by October 1875, so that production was expected to start in due course.
Rail vehicle wheels are usually mounted on a solid axle, so they turn at the same speed.When a vehicle turns the outer wheel has to travel further than the inner wheel. On a road vehicle, this is usually achieved by allowing the wheels to move independently, and fixing the front wheels in an arrangement known as Ackermann steering geometry.
In rail transport, a wheel arrangement or wheel configuration is a system of classifying the way in which wheels are distributed under a locomotive. [1] Several notations exist to describe the wheel assemblies of a locomotive by type, position, and connections, with the adopted notations varying by country.
The primary reason that the original RoadRailer concept was not viable was the weight penalty imposed on the trailers because of the attached railroad wheelset. This was resolved in later designs which removed the integrated wheelset by having a dedicated rail bogie assembly that stayed in the rail yard, as seen today. [citation needed] [9]
Steel tire on a steam locomotive's driving wheel is heated with gas flames to expand and loosen it so it may be slipped over the wheel.. The steel wheel of a steam locomotive and other older types of rolling stock were usually fitted with a steel tire (American English) or tyre (in British English, Australian English and others) to provide a replaceable wearing element on a costly wheel.
