FIELD: transport.SUBSTANCE: invention relates to railway transport, particularly, to railway freight car bogies. Bogie comprises two pairs wheels (2) connected by shaft in pairs (4) with a mounted axle. Said mounted axles (4) are interconnected by frame (6) including two semi-frames (8). Each of the latter comprises two lengthwise beams (10) interconnected by crosswise beam (12) resting on one of said mounted axles (4). Crosswise beams (12) are engaged by hinge (18) to allow turn of one semi-frame (8) relative to another one relative to another one about, in fact, lengthwise axis (A). Every lengthwise beam (10) of one semi-frame (8) is connected with lengthwise beam (10) of another semi-frame (8) by bar (20) articulated at said beams (10) to turn about, in fact, horizontal axes. Note that said bar (20) is located, at least partially, in horizontal plane shifted in height relative to horizontal plane extending through hinge (18).EFFECT: decreased bogie weight and bogie unsprung masses.10 cl, 3 dwg |
