damkia Posted June 12, 2012 Posted June 12, 2012 Old KoreelahMore intriguing, I'm not sure where 4x4 originated but is it the more specific description, for example 4x2 - 4 wheel groups, 2 driving 4x4 - 4 wheel groups, 4 driving 6x2 - 6 wheel groups, 3 driving (then a confusion, either a lazy axle, pusher axle or twin steer) 6x4 - 6 wheel groups, four driving 6x6 - 6 wheel groups, all driving 6x2 is a truck with lazy axle ie 6 "wheels" of which two wheels are driven (not 3) A "wheel" may consist of a single or double tyre on a rim6 x 4 is a powered double rear axle (ie one driveshaft to two differentials and 4 wheels). Other past time is 4WDing...
Guest Howard Hughes Posted June 12, 2012 Posted June 12, 2012 Now I'm going with 'aircraft' and 'airfield'. Now will you 'airheads' go find something else to do?? Would have thought you were a 'drome' man Pud!
turboplanner Posted June 12, 2012 Posted June 12, 2012 6x2 is a truck with lazy axle ie 6 "wheels" of which two wheels are driven (not 3) A "wheel" may consist of a single or double tyre on a rim6 x 4 is a powered double rear axle (ie one driveshaft to two differentials and 4 wheels). Other past time is 4WDing... Sorry, 3 was a typo. The 6x2 dosen't have to be a lazy axle - it can be a twin steer single drive.....which is why this nomenclature isn't perfect
kgwilson Posted June 12, 2012 Author Posted June 12, 2012 Unless hubs are locked at any one time only 1 wheel or set is actually putting power onto the road of the 2 wheels or sets connected through the same differential. So even in 4WD it is a 4x2.
damkia Posted June 12, 2012 Posted June 12, 2012 Unless hubs are locked at any one time only 1 wheel or set is actually putting power onto the road of the 2 wheels or sets connected through the same differential. So even in 4WD it is a 4x2. 4WD systems 101 One driveshaft goes to a differential which splits the torque between the two wheels via half shafts. On a dead straight road with 100% grip road the torque is spread equally between the two wheels. This is the same no matter which end the diff/axle is located. When the wheel on one side of the axle is in a high slip area (mud, etc) then all of the driveshaft rotational energy is expended turning that "free spinning" wheel with little to no torque getting through to the side with grip ("path of least resistance"). Locking differentials are used to remove the speed difference between sides of the axle in these cases, with the limitation that it makes turning more dificult on high grip surfaces due to the need for the wheels to turn at different speeds (inside vs outside wheel) when turning a corner. This speed difference is also applicable between the front and rear axles in any 4WD and known as "binding up" when turning a corner, resulting in possible destruction of the transfer case. Some vehicles use a center differential to equalise the speed differences between the driveshafts (Toyota Prado, mid-high end LandCruisers, RangeRovers, RR Discovery's), whereas some use a wet clutch pack to allow some slip (most AWD SUV's), and still others hope and pray thay you have common sense and have no center differential (low end LandCrisers, Hilux, Patrols etc). Back on topic..............
turboplanner Posted June 13, 2012 Posted June 13, 2012 Yes it had its day at the top of the tree, even if the quality was so bad that you would often find different seat colours in the same car.
Louis Moore Posted June 13, 2012 Posted June 13, 2012 meh. Airplane is easier to say. When unsure just go with "Dem Flyin Tings"
Herm Posted June 14, 2012 Posted June 14, 2012 I thought an Aeroplane was just a choc bar full of bubbles of nothing?I think you can also get an Aeromint as well! to many things to think about... Rolling 21
68volksy Posted June 14, 2012 Posted June 14, 2012 With their Up, Tiddly, Up, Up And Their Down, Tiddly, Down, Down. Up! Down! Flying Around. Looping The Loop And Defying The Ground. They're All, Frightfully Keen Those Magnificent Men, Those magnificent men, Those magnificent men and their flying machines!
kgwilson Posted June 14, 2012 Author Posted June 14, 2012 That's it then. Its not an Aeroplane, an Airplane, an Aircraft, a Plane, a Kite or a Ship its a FLYING MACHINE!
eightyknots Posted June 14, 2012 Posted June 14, 2012 It's interesting that the domain set apart for aviation is xxxxxx.aero. EG: www.zenith.aero Presumably an American thought of this?
kgwilson Posted June 14, 2012 Author Posted June 14, 2012 Obviously, they wouldn't have wanted xxxxxx.air as they would have been accused of being airheads. But really does AIR conjure up thoughts of flying or flying machines? To my mind AERO does.
