In the design of VM003.000 zero-clearancebearer, an elastic element made of thermoplastic elastomer is used.
High energy-absorbing properties of this
material allow the following:
Reduce wear of the railcar running parts
Increase the overhaul railcar run between repairs
Improve the dynamic features of the freight car
Designing and developing contact side bearings, the characteristics of elastic elements
are selected for new types of cars.
More stable railcar movement on curved track is achieved by means of immediate counteraction of the bearer to the wobbling rotational movement. The maximum effect of decreased car wobbling is reached athigh run speed.
