RAIL VEHICLE RUNNING GEAR Russian patent published in 2017 - IPC B61F5/32 

FIELD: transportation.

SUBSTANCE: running gear comprises a frame skeleton (107) having two longitudinal beams (108) and a cross member (109) connecting them in the middle. Each longitudinal beam (108) has a suspension coupling portion integrated with a free end (108.1) of the longitudinal beam (108) and forming a primary suspension coupling face (110) for the primary suspension device (105.1) connected to the corresponding wheel assembly (103). Each longitudinal beam (108) has a rotational conjugation portion (111) integrated with a portion of the primary hooking interface and forming a pivotal coupling for the pivot arm (112) connected to the corresponding wheel assembly (103). The primary suspension coupling face (110) is configured to reflect the resulting supporting force applied to the free end (108.1) when the frame skeleton (107) rests on the corresponding wheel assembly (103). The primary suspension coupling face (110) is configured such that the resulting supporting force is inclined relative to the longitudinal direction and the height direction with forming a primary suspension angle that is from 40° up to 50°.

EFFECT: compact design.
