A disk cipher device of the Jefferson type from the 2nd quarter of the 19th century in the National Cryptologic Museum. The Jefferson disk, also called the Bazeries cylinder or wheel cypher, [1] was a cipher system commonly attributed to Thomas Jefferson that uses a set of wheels or disks, each with letters of the alphabet arranged around their edge in an order, which is different for each ...
A = number of wheels (twin-mounted tires count as one wheel) B = number of driven wheels / = the fore of the rear axles is steered (pusher axle) * = the rearmost of the rear axles is steered (tag axle) C = number of steered wheels - = separates axle groups and/or different axle functions (6x4-2 is 6x6 with undriven rear axle)
The first Dana 70 axles had a 1 ⁄ 2-inch (13 mm) pinion offset and were found in Dana 70HD's as well. The drawback with the 1 / 2-inch offset was that a 4.10:1 gear ratio was the highest gear set possible. In the 1970s the 1 / 2-inch offset was phased out for a 5 ⁄ 8-inch (16 mm) offset that allowed
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 UIC classification of locomotive axle arrangements, sometimes known as the German classification[1] or German system, [2][3] describes the wheel arrangement of locomotives, multiple units and trams.
