The main focus of this chapter are the bogie features that are directly or indirectly related to the axlebox application. Design principles A bogie is a structure underneath a railway vehicle body to which axles and wheels are attached through bearings. The term bogie is used in British English, while a wheel truck, or simply truck is used in American English. The overall term is running gear, which covers bogies as well as vehicles with two, or more axles without any bogies. In this case, these axles are directly fitted to the vehicle body via guiding devices and springs, and for very low speeds even without springs. Running gears serve a number of purposes: support of the rail vehicle body stability on both straight and curved tracks providing ride comfort by absorbing vibration, and minimizing centrifugal forces when the train runs on curves at high-speed minimizing generation of track irregularities and rail abrasion In this chapter, the focus is on some general bogie design principles and especially design features that interact with the axlebox bearing system.

The primary spring acts between the wheelset via the axlebox bearing and the bogie frame. On sharp curves, the frequency of sleepers often needs to be increased. What you don t know can cost you time, money. Structural changes occur underneath the raceway surface and micro cracks develop.

This system helps to provide a more convenient and comfortable ride on trains. Preparing for use The dynamic forces raillway on an inboard axlebox bearing can be heavier compared to outboard applications? It could save your life.

The 3-axle bogie design railwway a special lateral movement of the middle axle by running curved tracks. The author cannot guarantee the accuracy. There are several notations used to describe wheelset and wheel arrangements, which vary by country. Suspension by two parallel steel leaf springs acting on one side of the axlebox housing, which is equipped with helical springs.

The vehicle body is able to move laterally relative to the bogie against the restoring force of the springs.

One of the most difficult tasks is identifying the root cause and filtering out any secondary effects that resulted from the root cause of failure!

    Lower-case o designates axles, which are individually driven by electric traction motors in locomotives and multiple units. In the case of a stationary bearing, the depressions appear at rolling element pitch and can often be discoloured reddish or shiny lines for roller bearings. The secondary spring is integrated into the transversal beam design. A rubber blanket is used as primary suspension between the adapter and the suspension.

    SKF developed this habdbook method for bearings in railway applications to analyse the elastic behaviour of the cage under all types of vibrations and shocks, such as the influence of wheel flats and rail joints.
