bogie

, bogy
1. an assembly of four or six wheels forming a pivoted support at either end of a railway coach. It provides flexibility on curves
2. Chiefly Brit a small railway truck of short wheelbase, used for conveying coal, ores, etc.

[′bō·gē]
Also spelled bogey; bogy.
(aerospace engineering)
A type of landing-gear unit consisting of two sets of wheels in tandem with a central strut.
(engineering)
A supporting and aligning wheel or roller on the inside of an endless track.
A low truck or cart of solid build.
A truck or axle to which wheels are fixed, which supports a railroad car, the leading end of a locomotive, or the end of a vehicle (such as a gun carriage) and which is allowed to swivel under it.
A railroad car or locomotive supported by a bogie.
(mechanical engineering)
The drive-wheel assembly and supporting frame comprising the four rear wheels of a six-wheel truck, mounted so that they can self-adjust to sharp curves and irregularities in the road.
(mining engineering)
A small truck or trolley upon which a bucket is carried from the shaft to the spoil bank.

Justin Keeley, Bombardier's chief engineer in the bogies division, says: "With a normal bogie, you have four wheels with a rigid H-frame.
Each Zefiro bogie will travel for long periods at 360km/h with a load of up to 32,000kg upon it and have its first major overhaul after five years, during which it will have travelled 2.
Historically, most of the bogie division's work has supported Bombardier's mainline train-building programmes, such as the current contract to make 130 class 377 vehicles for Southern at the Derby plant.
Indeed, it was a Bombardier bogie designed for the Chinese market that acted as the basis for the Trenitalia contract.
The end solution offered for Trenitalia was an active lateral suspension design--a bogie technology that provides a way of manipulating the suspension, principally to achieve a better ride for passengers.
When the train goes through a curve, the bogie follows the curve first, bringing the carbody with it.
All of Alstom's future bogies will be tested at the Neuhausen centre.
This process, said the company, gave an on-going appreciation but did not allow a full anticipated validation of the bogie for 30 years of service.
For example, checks can be run on the performance of a bogie equipped with all its components during slow or rapid acceleration phases, whether in a straight line or in a curve.
So, before being put into service, an Alstom bogie equipped with all its components will have undergone at least 10 million fatigue test cycles which, in a period of just four to six months, will simulate nearly 30 years of service.
For example, Alstom has equipped the Ixege bogie for the Citadis tramways with more than 460 stress, temperature, torque measurement and displacement sensors.
With improvements expected to be made on the new bogie test bench, it will eventually be possible to simulate a route with even greater precision by incorporating possible track defects.
