FIELD: railway transport; design of main frames of rail vehicles.
SUBSTANCE: proposed frame contains one or two center sills 1, side beams 3, cross beams, front beams or sheets, supports, devices to take up traction forces from bogies or axles and devices for mounting draft gears and automatic couplers. Center sills and at least two cross beams are made in form sidemembers of closed seamless sections or welded section made of sheet or shaped material or their combination. Side beams are made in form of sidemembers of closed seamless sections or welded sections made of sheet or shaped material or their combination. Stops limiting side shift of body 18 installed on center sills or on cross beam or on brackets of tie rod 16 are displaced from middle support plane to each bogie in direction of middle cross plane of frame.
EFFECT: provision of required strength of frame at reduction of its mass, increased traction, dynamic and service and repair qualities of rail vehicle.
