Connecting rod and coupling rods attached to a small locomotive driving wheel. In general, all railroad vehicles have spring suspension; without springs, irregularities in the track could lift wheels off the rail and cause impact damage to both rails and vehicles. Driving wheels are typically mounted so that they have around 1 inch (2.5 cm) of ...
On a conventional, non-articulated locomotive, the driving wheels are all coupled together with side rods (also known as coupling rods); normally one pair is directly driven by the main rod (or connecting rod) which is connected to the end of the piston rod; power is transmitted to the others through the side rods. [2] [3] [4]
Wheels coupled to the main/side rods, through which the power developed in the cylinders (24) is transformed into tractive power at the rails. [1] [2] [5] [3]: 28 The weight of bearings and coupling rods on the driving wheels is counterbalanced with cast-in weights to reduce "hammering" on the track when the locomotive is under way. [3]: 21
The coupling rod between those axles was 'triangular', with an additional bearing mounted on its top edge, taking the thrust of the jackshaft drive rod. Unlike most connecting rods, this allows it to be mounted in the same plane as the coupling rod bearings. This reduces the overhung lengths of the crankpins and their bending loads.

The Twilight Zone creator Rod Serling would have turned 100 on Dec. 25, 2024. To commemorate the anniversary, Rod’s daughters, Jodi and Anne, are looking back on some of their most meaningful ...
The very famous example is the joining of piston rod's extension with the connecting rod in the cross head assembly. Advantages: Quick assembly and disassembly is possible; It can take tensile as well as compressive force. Application: Joint between piston rod and cross head of a steam engine; Joint between valve rod and its steam
The eccentric crank (UK: return crank) (1) is rigidly attached to the con-rod pin connected to the main drive wheel. Note that this is the only suitable attachment point on any of the drive wheels that is not fouled by the passage of the coupling rod or the connecting rod. The eccentric crank is of a length such that the pin attachment to the ...
