FIELD: railway transport. ^ SUBSTANCE: proposed rail vehicle has frame 1 and body resting on two-axle bogies 4 with frames 5. according to first design version, extreme wheelsets of rail vehicle are furnished with bellcranks 11 rigidly connected by lower ends with axle boxes 7, hinge connected by middle parts by longitudinal ties with frames of bogies, and by upper ends said bellcranks are hinge-connected with by longitudinal ties frame or body of rail vehicle. According to second design version, extreme and middle wheelsets of rail vehicle are furnished with bellcranks hinge-connected or rigidly connected by lower ends with axle boxes, hinge-connected by middle parts by longitudinal ties with frames of bogies and hinge-connected by upper ends by ties with frame or body of rail vehicle. According to third design version, extreme and middle wheelsets of rail vehicle are furnished with bellcranks which are hinge-connected or rigidly connected with axle boxes of extreme wheelsets by lower, and with axle boxes of middle wheelsets by middle parts. Bellcranks of extreme wheelsets are connected by their middle parts and those of middle wheelsets are hinge connected by lower ends by longitudinal links or tie-rods with frames of bogies, and by upper ends bellcranks of extreme and middle wheelsets are hinge-connected by longitudinal links or tie-rods with frame or body of rail vehicle. ^ EFFECT: improved dynamic and operating characteristics, provision of radial setting of wheelset axles, reduced resistance to running, wear of tires and flanges of wheels. ^ 6 cl, 5 dwg
