| 摘要 |
<p>The present invention relates to a running gear unit for a rail vehicle, comprising a running gear frame body (107) defining a longitudinal direction, a transverse direction and a height direction. The frame body (107) comprises two longitudinal beams (108) and a transverse beam unit (109) providing a structural connection between the longitudinal beams (108) in the transverse direction, such that a substantially H-shaped configuration is formed. Each longitudinal beam (108) has a suspension interface section associated to a free end section (108.1) of the longitudinal beam (108) and forming a primary suspension interface (110) for a primary suspension device (105.1) connected to an associated wheel unit (103). Each longitudinal beam (108) has a pivot interface section (111) associated to the primary suspension interface section and forming a pivot interface for a pivot arm (112) connected to the associated wheel unit (103). The primary suspension interface (110) is configured to take a total resultant support force acting in the area of the free end section (108.1) when the frame body (107) is supported on the associated wheel unit (103). The primary suspension interface (110) is configured such that the total resultant support force is inclined with respect to the longitudinal direction and inclined with respect to the height direction.
