Patent ID: 8813654

Claim:
A running gear frame for a rail vehicle comprising: a central transverse beam, and two longitudinal beams rigidly connected together in a frame transverse direction via said central transverse beam, wherein said central transverse beam has at least a front web element, a rear web element and a transverse beam lower chord, said web elements run between said longitudinal beams in said frame transverse direction and in a frame height direction, and are connected with said longitudinal beams, and are arranged spaced apart in a frame longitudinal direction at least by a web element distance, said transverse beam lower chord is substantially plate shaped and extends on an underside of said central transverse beam from one of said longitudinal beams to the other one of said longitudinal beams and is connected with said web elements, said transverse beam lower chord, in at least one longitudinal protrusion extending in said frame transverse direction over a longitudinal protrusion region of said central transverse beam, extends beyond said front web element and/or said rear web element in said frame longitudinal direction by at least 10% of said web element distance, and wherein central longitudinal axes of said longitudinal beams, in said frame transverse direction, are spaced apart by a longitudinal beam distance and said longitudinal protrusion region, in said frame transverse direction, is located between two longitudinally recessed parts of said transverse beam lower chord, such that longitudinal protrusion region extends over 30% to 70% of said longitudinal beam distance.
