A rail vehicle wheelset, comprising two wheels mounted rigidly on an axle A wheelset is a pair of railroad vehicle wheels mounted rigidly on an axle allowing both wheels to rotate together. Wheelsets are often mounted in a bogie (" truck " in North America ) – a pivoted frame assembly holding at least two wheelsets – at each end of the vehicle.
The Schwab coupler is an automatic coupler manufactured by Schwab Verkehrstechnik AG, Schaffhausen, the legal successor to the Railway Coupler Division of Georg Fischer. The coupler automatically makes the mechanical, pneumatic and electrical connections. The mechanical locks are located on either side of the pneumatic ports.
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).
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.
The diagram from Beard's 1897 coupler patent [7]. Janney couplers were first patented in 1873 by Eli H. Janney (U.S. patent 138,405). [8] [9] Andrew Jackson Beard was amongst various inventors that made a multitude of improvements to the knuckle coupler; [7] Beard's patents were U.S. patent 594,059 granted 23 November 1897, which then sold for approximately $50,000, and U.S. patent 624,901 ...
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.
Side friction wheels keep the train centered in the track, avoiding derailment. The final set of wheels in the assembly are known as running wheels, road wheels, or tractor wheels. Running wheels are typically the largest set of wheels in the assembly, and roll on the top of the rails. These wheels bear the weight of the train.
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.
