What is the use of coupling rod of locomotive?

A coupling rod or side rod connects the driving wheels of a locomotive. Steam locomotives in particular usually have them, but some diesel and electric locomotives, especially older ones and shunters, also have them. The coupling rods transfer the power of drive to all wheels.

How does a steam engine increase speed?

The speed of the engine is regulated by the “cut-off,” which consists of a plate of metal placed to fit and work on the back of the slide valve, which is furnished with certain openings through which the steam must pass into the cylinder while the cut-off plate is in a proper position.

What causes locomotive wheel slip?

Causes. The causes of locomotive wheelslip vary, but the predominant factor lies in the power-to-weight ratios. However, if the power of a locomotive vastly exceeds its weight, then an imbalance ensues which causes the violent spinning of the wheels through loss of traction.

What is coupler rod?

Coupling rods are used to connect a locomotive’s driving wheels together. Also known as a side rod, a coupling rod is used to connect a locomotive’s driving wheels together. Steam locomotives have two pistons, with one on each side of the locomotive.

How does a train coupling work?

Today’s standard freight-car coupler is the Type E, a Janney “clasped-hand” device that couples automatically when one or both knuckles are open and cars are pushed together. Lifting the lever unlocks the knuckle and lets it swing open, allowing the cars to be pulled away from each other.

How do trains connected to each other?

During coupling, They are then linked together by an automatic coupler, consisting of: mechanical systems to ensure the connection between the two trains, pneumatic ducts to guarantee continuity between the two trains, and finally, electrical connector heads to allow both trains to be controlled from a single cabin.

How does a steam traction engine work?

When heated, water turns to an invisible vapor known as steam. The volume of water expands as it turns to steam inside the boiler, creating a high pressure. The expansion of steam pushes the pistons that connect to the driving wheels that operate the locomotive.

What does a governor do in a steam engine?

A steam turbine governor is a component of the turbine control system that regulates rotational speed in response to changing load conditions. The governor output signal manipulates the position of a steam inlet valve or nozzles which in turn regulates the steam flow to the turbine.
