RADIAL WELDED TRUCK Russian patent published in 2015 - IPC B61F3/02 B61F5/04 B61F5/38 B61F5/52 B61F7/00 B61H1/00 

FIELD: transport.

SUBSTANCE: truck includes two wheelpairs (1), welded side beams (5) and assembly (7) of cross beam which take the form of three-link structure. Both ends of side beam are connected with wheelpairs via main rubber-metal pad (4) and adapter (2) located on bearing (13) of wheelpairs. Two wheelpairs are interconnected via adapter and wheelpair connecting device (3). Cross beam assembly is connected with side beam via two additional suspension systems (6). The main breaking device (8) is suspended on assembly of cross beam or side beam. Wheelpair connecting device contains two arc rods (31) and one arc rod connecting part (32). Both ends of arc rods are connected with adapter by means of bolting, riveting or welding. The arc rod connecting part represents structure of rubber spherical articulated joint (321) or spherical bearing (322).

EFFECT: reduced wheel-rail force and wear of suspension system parts, higher stability of truck during high-speed movement and reduced wear of rim when truck runs over curved rail.
