Abstract
A running gear frame for a rail vehicle includes a central transverse beam, and two longitudinal beams connected together in a frame transverse direction via the transverse beam, wherein the transverse beam has at least a front web element, a rear web element and a transverse beam lower chord. The web elements run between the longitudinal beams in the frame transverse direction and in a frame height direction and are connected therewith and are arranged spaced apart in a frame longitudinal direction. The transverse beam lower chord extends on an underside of the transverse beam between the longitudinal beams and is connected with the web elements. Furthermore, the transverse beam lower chord extends beyond the front web element and/or the rear web element by at least 10% of the web element distance.
