Innovative bogie

Reinforced side frame construction has better strength and fatigue resistance and contributes to a safer use of the bogie. The surfaces subjected to wear have removable protection plates which ensure wear protection for a distance of up to 1 million km.

The configuration of the bolster ensures an equal stress condition under loads. Removable wear-resistant elements of the parts protect them from wear and tear for a distance of up to 1 million km.

All-rolled wheels of increased hardness with curvilinear disks are able to endure increased loads.

Constant contact side bearings made of high-strength cast iron improve freight car dynamic performance and provide for high wear-resistance of the friction pair for a distance of up to 1 million km. Using springs as elastic elements allows to keep side bearing strength parameters stable even at low temperatures.

Friction wedges made of high-strength cast iron provide for stable friction parameters and ensure a better wear protection for a distance of up to 1 million km. The use of composite wedges helps to minimize side frame “lozenging”.

Heavy-duty spring suspension resists to compression when in operation with the coil winding gap maintained the same which prevents the coils from colliding with each other.

The tapered cassette-type bearing supporting the side frame via an adapter reduces the bogie’s unsprung weight and improves its movement parameters. Made of high-strength cast iron, the adapter possesses high resistance to wear and lasts for a distance of up to 1 million km. As well as the bogie, the bearing is designed for a overhaul period of 1 million km.

The new design of the wear bracket of the pedestal jaw opening ensures a higher reliability.

Reinforced bolster and side frame castings have a service life of 40 years with an axle load of up to 27 tf.

The new constant-contact side bearing has a higher resistance to wear and is more reliable.

The new spring suspension with the static deflection increased by 50% is able to reduce the dynamic component of the vertical and side forces acting on the track.
