Abstract

FIELD: rail vehicles.SUBSTANCE: invention relates to the field of spinal beams of railcar frames. Built spinal beam contains the coupler stops, the end sections and the middle part. Stops are designed for basing the shock-traction equipment of the car. End sections are made in a shape of two welded z-shaped profiles. Middle part can be made of sheet metal or of shaped corners. Walls of the middle part are connected to each other by jumpers.EFFECT: reduced mass of spinal beam is achieved.3 cl, 5 dwg

Description

The invention relates to the field of railway transport and can be applied in the design of the ridge beam of the frame of a freight car.

Well-known spinal beam gondola containing rigidly interconnected lower beam and upper beam; the lower beam contains upper and lower vertical sheets rigidly interconnected by vertical sheets, and the upper beam contains one horizontal shelf and one wall rigidly connected to it, or two or more walls intended for fixing with fastening elements of discharge covers, (see Patent en 59680 IPC B61F 1/02, published Feb 20, 2016)

The well-known spinal beam of the gondola consisting of rigidly interconnected lower beam and upper beam welded to the lower beam along its longitudinal axis. The lower beam is made of a single, in particular, curved, omegoobrazny profile with a horizontal base, vertical walls, and two lateral horizontal shelves (see patent ru 169001 IPC B61F 1/02, publ. 03/01/2017)

The disadvantage of the above structures spinal beams of cars, is the high complexity of the manufacture of spinal beams, which are composite lengthy structures made of a Zeta profile forming a cross section. Also, the problem of spinal beams made of a single profile, in particular cases, of a bent omegoobrazny profile is the laboriousness of making a bent profile so long and requiring the use of special equipment.

The technical result of the invention is to reduce the mass of the ridge beam, the frame and the entire car, and as a result of the entire rolling stock, to increase the maintainability of the ridge beam, reduce the consumption of materials and the complexity of manufacturing the ridge beam.

This technical result is achieved by the fact that in the composite ridge beam, which is included in the frame of the freight car, and is used for basing and connecting the body with the car frame, including the stops of the coupler in the end parts and the middle part of the beam, the console parts of the ridge beam in which the front and the rear stops for the basing of the shock-traction equipment of the car, are made of a Z-profile, forming a cross-section, the middle part connecting the cantilever beams is made of two longitudinal parts filled with their sheet metal, or two longitudinal parts made of shaped profile-angle, interconnected by welded jumpers of T-section. The lintels are located along the middle part of the spinal beam according to dimensional bindings, ensuring their basing and location opposite the transverse beams and profiles of the body frame. The connection of the spinal beam with cross beams and body frame straps, realized through the closure of the body frame strapping circuit with jumpers of T-section.

The construction of the middle part of the composite spinal beam thus significantly reduce the weight of the structure, the weight is reduced due to the fact that the beam is not completely made of two zetine profiles forming a cross section along the entire length of the beam, but of the component parts. Improving the maintainability of the beam is achieved by a simplified system for replacing parts.

The invention is illustrated by drawings, which do not cover and, moreover, do not limit the entire scope of the claims of this technical solution, but are only illustrative materials of a particular case of execution:

The composite spinal beam, which is included in frame 1 (Fig. 2) of a freight car, and serves for basing and communication of the body 2 (Fig. 1) with frame 1 (Fig. 2) of the car, including stops of the coupler 3 (Fig. 1) in the end parts and the middle part of the beam, characterized in that the cantilever parts of the ridge beam in which the front 5 (Fig. 1) and rear 6 (Fig. 1) abutments for the base of the impact-traction equipment of the car 7 (Fig. 1) are placed, are made of zeta profile 8 (Fig. 2), forming a omegoobraznoe section, the middle part connecting the console beams is made of d yi longitudinal parts made of sheet metal 9 (Fig. 3), or two longitudinal parts made of shaped profile angle 10 (Fig. 3 option), interconnected by welded jumpers of T-section 11 (Fig. 3, Fig. 3 option) .

Jumpers 11 (Fig. 3, Fig. 3 variant) are located along the middle part of the sill beam along dimension bindings, ensuring their basing and location opposite the transverse beams 12 (Fig. 4) and profiles of the frame body 13 (Fig. 4).

The connection of the ridge beam with transverse beams 12 (Fig. 4) and straps of the body frame 13 (Fig. 4), realized through the closure of the contour of the straps of the frame of the body 13 (Fig. 4) with jumpers of the T-section 11 (Fig. 3, Fig. 3 option ).
