Claim:
1. A running gear unit comprising: a running gear frame body defining a longitudinal direction, a transverse direction and a height direction; said frame body comprising two longitudinal beams and a transverse beam unit providing a structural connection between said longitudinal beams in said transverse direction, such that a substantially H-shaped configuration is formed, each longitudinal beam having a suspension interface section associated to a free end section of said longitudinal beam and forming a primary suspension interface for a primary suspension device connected to an associated wheel unit; each longitudinal beam having a pivot interface section associated to said primary suspension interface section and forming a pivot interface for a pivot arm connected to said associated wheel unit; said primary suspension interface being configured to take a total resultant support force acting in the area of said free end section when said frame body is supported on said associated wheel unit; wherein said primary suspension interface is configured such that said total resultant support force is inclined with respect to said longitudinal direction and inclined with respect to said height direction, said primary suspension interface defines a main interface plane; said main interface plane being configured to take at least a major fraction of said resultant support force; said main interface plane being inclined with respect to said longitudinal direction and inclined with respect to said height direction; said main interface plane being inclined with respect to said height direction by a main interface plane angle, said main interface plane angle ranging from 40° to 50°; and said main interface plane being substantially parallel with respect to said transverse direction.
