Abstract
A railway vehicle bogie, including at least two axles, at least one side member being provided to connect the axles to a central part of the bogie. The side member is formed by an elastic blade shaped as a vertically oriented continuous flattened loop which may be made of composite material or of metal. A process for manufacturing a side member of composite material consists in winding a continuous lap of reinforcing fibers over at least one turn around two studs so as to form a loop, and polymerizing a resin-based matrix around the fibers.
