Talk:Bogie

"tram bogies often neeed to pivot on the horizontal axis as well" Do bogies on railway carriges and railcars also allow for this? I might reword some section if this is the case.Myrtone (the strict Australian wikipedian)

Too much detail about certain types instead of generalities.

I think the detailed information about certain types of passenger coach bogies in use in the UK should be farmed out to separate articles; it's too specific and gives the article an unnatural focus. Instead we need more generalities about the uses and technologies of bogies. Matthew Brown (Morven) (T:C) 01:38, 13 October 2007 (UTC)

How is it now? I need to dig up some more sources though. Wongm (talk) 13:18, 20 December 2007 (UTC)

I thought it was too UK-centric so I've added more US information. Hope I haven't overdone it. Biscuittin (talk) 21:03, 3 July 2009 (UTC)

Powered bogies

In point number five,the article mentions "some form of transmission, usually an electrically powered traction motors or a hydraulically powered torque converter." It might be worth adding that often this will be via a cardan shaft to minimise axle load. 81.152.161.60 (talk) 14:26, 31 October 2011 (UTC)

Caterpillar

Use of the company "Caterpillar Inc" should at least have a reference to their site and be properly capitalized. — Preceding unsigned comment added by 98.214.168.10 (talk) 20:04, 13 November 2011 (UTC)

Not all caterpillar tracks are the product of Caterpillar Inc. --Redrose64 (talk) 20:26, 13 November 2011 (UTC)

Unclear Terminology

What is a bolster? What is a plank? What is special about a bogie bolster wagon? Chevin (talk) 16:29, 16 March 2012 (UTC)

Er. Bolster has two different meanings in railways.

On a bogie, the bolster is the component carrying the pivot, and is connected to the bogie frame via the secondary suspension; see this diagram - it's the component running across the middle carrying the center plate and side bearing.

A bolster wagon is a flat wagon with one or more transverse timber baulks known as bolsters; such wagons carry long thin loads such as timber, steel sections, pipes and the like. The load is prevented from rolling sideways by chains, vertical stanchions or both; this photo shows a timber wagon with the bolsters and stanchions painted blue. In Britain, bolster wagons having one or two bolsters are usually four-wheeled; those with three or more bolsters (the LNER had some with seven bolsters) are mounted on bogies, and these are known as bogie bolster wagons. --Redrose64 (talk) 17:08, 16 March 2012 (UTC)

Thanks for that. Never been able to get a straightanswer to that Chevin (talk) 17:36, 16 March 2012 (UTC)

patent of 1883 by James Cleminson citation

In previous citation, url towards library with temporary pass was used. I've removed dead link towards it, but I was unable to find replacement link for pdf or any equivalent source that could be used as a citation Skeledzija (talk) 11:12, 27 November 2012 (UTC)

You shouldn't really remove such links (see WP:LINKROT); if you can't find a replacement, you should mark it as inaccessible. If the link is truly dead, add {{dead link}}; if the page exists, but needs registration for access, add {{registration required}}; if you also need to pay for access, use {{subscription required}} instead. --Redrose64 (talk) 14:02, 27 November 2012 (UTC)

I'm really sorry, I'll make sure it doesn't happen again. Sorry for making you do extra work.Skeledzija (talk) 15:57, 27 November 2012 (UTC)

Truck bogie

Bogie of Sisu K-44.

I have got a question regarding use of "bogies" in trucks. When you check the Swedish, Norwegian and Finnish articles also truck and bus bogies are mentioned. They are missing from this article, so is there another name in English for truck and bus "bogies" or is the arrangement just unknown in the English speaking world? --Gwafton (talk) 10:56, 15 March 2013 (UTC)

Sisu Auto's website tells about bogie: [1]. Is the term correct or not? --Gwafton (talk) 13:36, 15 March 2013 (UTC)

Is the correct term tandem axle for a this kind of arrangement? --Gwafton (talk) 22:49, 18 March 2013 (UTC)

Unfortunately, different people use the terms in different ways... depending on which source/context you look at, "tandem axle" can mean as little as "two, separate axles" or it could mean as much as "two axles, designed as a pair" in a sense which is closer to a bogie. In English, a bogie implies a fixed combination of two (or three) axles, so you'd typically find people talking about a bogie on an 8x4 tipper &c. Obviously a 3-axle bogie isn't "tandem" any more. bobrayner (talk) 13:19, 21 March 2013 (UTC)

In EU legislation two separate axles of which suspensions are independent from each other, with wheelbase max. of 1100, are called double axle. There is a clear difference between these two systems in legislation but this doesn't seem to be the case in spoken language. The three axle system is called tridem. You can find such for example in Dutch GINAF trucks.

However, the article I am currently working on speaks now about tandem axle. Someone can change it if he/she has got evidence that the system is definitely called bogie. Then the description about truck bogies should be included in this article as well. --Gwafton (talk) 21:43, 22 March 2013 (UTC)

Centrifugal Force

Does anyone understand this "minimizing centrifugal forces" reference in the opening list of purposes. It kind of sounds like something copied from article to article without it being questioned, which is what I'm doing. It does not seem to me that any reduction in forces would apply EXCEPT that the forces would be distributed over more wheels. Rjstott (talk) 16:44, 10 April 2013 (UTC) Looked up the reference and the statement here misquoted it so I'm changing it Rjstott (talk) 08:06, 13 April 2013 (UTC)
