Solid wheel for a rail vehicle and method for producing the wheel

A method for producing a solid wheel, comprising:

• arranging a wheel rim on a circumference of the solid wheel;
• providing a tread on the rim;
• and
• connecting a hub for a wheel set shaft to the wheel rim by an end wall and a rear wall, said hub being arranged at a center of the solid wheel and having a longitudinal axis;
• wherein the solid wheel forms a cavity which is delimited by the end and rear walls;
• wherein the end and rear walls transition into each other below the wheel rim in an arched manner;
• and
• wherein the end wall has first openings and the rear wall has second openings in order to open the cavity outwardly;
• wherein the solid wheel is produced in one piece as a cast part;
• wherein the second openings have a second axis of symmetry and are configured to be substantially egg-shaped;
• wherein the second axis of symmetry intersects the longitudinal axis;
• and
• wherein the second openings, when perpendicular to the second axis of symmetry, have a greatest width in a region which is offset radially in a direction of the tread relative to a central point of the second opening.
