Abstract
A wheel set for railway vehicles, especially high speed railway vehicles in which hollow shaft sections on a shaft are connected by an elastic coupling for limited relative angular displacement of the wheels. The elastic coupling is of the deformable elastomeric, viscoelastic or hydraulic type.
Claims7
A torsionelastic wheel set for a railway vehicle comprising:
- a shaft;
- a pair of axially spaced track-entrained railroad-rail wheels independently journaled on said shaft and rotatable relative to said shaft and to one another;
- respective hollow shaft sections connected to each of said wheels and disposed between said wheels, said shaft extending through said sections, said shaft sections being cylindrical and extending toward a location substantially centrally disposed between said wheels, each of said shaft sections having a flange adjoining said location;
- and
- an annular elastic coupling at said location between said hollow shaft sections coaxial therewith and securing them together substantially midway between the wheels for limited elastic relative angular displacement and generating a restoring force reestablishing an original angular orientation of said hollow shaft sections, said coupling being axially sandwiched between said flanges.
