摘要： The present invention relates to a running gear frame for a rail vehicle, in particular, a rail vehicle having a nominal speed above 160 km/h, comprising a running gear frame unit (107) defining a longitudinal axis, a transverse axis and a height axis and comprising two longitudinal beams (108) and at least one transverse beam (110). Each of the longitudinal beams (108) extends along the longitudinal axis of the running gear frame unit (107), while the at least one transverse beam (110) extends along the transverse axis of the running gear frame unit (107). The at least one transverse beam (110) is substantially rigidly connected to at least one of the longitudinal beams (108) in the area of a joint location (111). The at least one longitudinal beam (108), at least in the region of the joint location (111), has a longitudinal web section (108.4) extending in a web plane perpendicular to the transverse axis, a web joint part (110.9) of the transverse beam (110) being connected to the longitudinal web section (108.4). The at least one transverse beam (110), at least in the region of the joint location (111), is an open structure element such that, in a sectional plane perpendicular to the transverse axis and located at the joint location (111), the transverse beam (110) has an open, non-ring-shaped profile cross section. The open profile cross section has a first free end (110.1) and a second free end (110.2), wherein a transverse beam inner contour is defined by a connecting line (110.4) between the first free end (110.1) and the second free end (110.2) and an inner circumference of the profile cross section between the first free end (110.1) and the second free end (110.2). The longitudinal web section (108.4) has an aperture located in the region of a transverse beam projection, wherein the transverse beam projection (TBP) is a projection of the transverse beam inner contour along the transverse axis onto the web plane, the transverse beam projection (TBP) confining a transverse beam projection area (TBPA). The aperture (112) defines an aperture projection (AP), wherein the aperture projection (AP) is a projection of the aperture (112) along the transverse axis onto the web plane, an outer contour of the aperture projection (AP) confining an aperture projection area (APA). The aperture projection area (APA) at least partially overlaps the transverse beam projection area (TBPA), and the aperture projection area (APA) corresponds to at least 60%, preferably at least 75%, more preferably at least 85%, of the transverse beam projection area (TBPA).
