The tires of large Conestoga wagon rear wheels usually measure 3.75 in (95 mm) to 4 in (100 mm) in width while those of medium Conestoga wagon rear wheels measured about 3 in (76 mm) in width. Conestoga wagons used for hauling and farming may have been complemented with different wheel size sets for performing different transversal duties, from ...
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.
The rails generally slant inwards at 1 in 40, a lesser angle than the wheel cone. 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 ...
The Conestoga wagon was a heavy American wagon of English and German type from the late 18th century and into the 19th century. It was used for freight and drawn by teams of horses or oxen depending on load. The covered canvas top was supported on eight to twelve angled bows, rather than upright. Capacity was around 4 to 5 tons with no springs.
A round plate with a hole in its centre is located on the underside of the wagon. The plate on the wagon, in turn, sits on the plate on the axle between the wheels. This arrangement allows the axle and wheels to turn horizontally. The pin and hole arrangement could be reversed. The horse harness is attached to this assembly.
A bogie in the UK, or a railroad truck, wheel truck, or simply truck in North America, is a structure underneath a railway vehicle (wagon, coach or locomotive) to which axles (hence, wheels) are attached through bearings. In Indian English, bogie may also refer to an entire railway carriage. [4]
An overheated wheel bearing. This comes from the era before the widespread use of roller bearings where the ends of an axle rested in solid copper bearings housed in a journal box filled with oil soaked cotton waste. An overheated axle led to a hot journal box that often ignited the oiled waste. The term is used to refer to a railway wheel ...
A four-wheel wagon was rated at 10 Tons capacity, and three axles at 15 Tons. [ 224 ] [ 225 ] Peter Vincent has hypothesised that this traffic would have operated in conjunction with horse box vehicles, requiring coordination in advance because the latter would often be used individually for race traffic.
