Abstract
In the paper is presented some theoretical considerations underlying the use of these springs in the railway vehicle constructions. The use of these springs as elastic suspension systems is justified by a few advantages that they offer in service, such as: simplicity, weight and low gauge, do not require guides, work without wear and have a high reliability. The elasticity in the three-principal: vertical, horizontal-transverse and longitudinal directions recommends the use of these springs in the axle’s suspension of the vehicle. As an application it is presented the axle suspension dimensioning elements in the case of a carload subway vehicle.
