A known cross member of a truck frame, consisting of a pipe and cast brackets rigidly connected to its ends, mating with the pipe with its cylindrical part and having a support flange and stiffeners made in one piece, brackets, brackets at the place of stiffening ribs have a conical shape with an extension of side of the flange, and their cylindrical part mates with the inner surface of the pipe, while the ends of the pipe at the interface with the brackets are made with holes for welding (see utility model patent RU No. 116449 U1, IPC B62D 21/02 (2006.01), published 27.05 .2012).

Known cross member of the vehicle frame, containing at least one beam made with recesses at the ends, fasteners in the form of scarves, the horizontal walls of which have bevels to the central part, and the vertical walls are made with mounting holes, there are two channel type beams, interconnected by vertical walls, the lower horizontal walls of the kerchiefs are larger than the upper ones, and their bevels are made with a radius, while the vertical walls of the kerchiefs are beveled on the sides (see utility model patent RU No. 130283 U1, IPC B62D 21 / 02 (2006.01), published on July 20, 2013).

A vehicle frame cross member is known, which contains two stamped curved sheets connected to each other by their central parts with rivets and directed by the curved side to one side up, while the ends of the sheets are made with curved ends at different angles, which are directed downwards and have holes for fastening to right and left frame side members (see the website on the Internet: http://www.tgkonvent.ru/detail.php?id=1702&shop=kamaz&lan=en).

The prototype of the claimed technical solution according to the set of essential features and the achieved technical result is the cross member of the vehicle frame, made of an open profile, expanding to the end surfaces, with a functional cutout in the lower part, having two vertical side walls and a horizontal shelf with fastening elements at the ends directed in the opposite direction from each other and with mounting holes, while the frame cross member has a U-shaped profile, and its functional cutout is made with punchings (see utility model patent RU No. 134138 U1, IPC B62D 21/00 (2006.01), published 10.11 .2013).

Known solutions have structural and technological complexity, complicate the complexity of attaching parts to the cross member of the frame.

The task to which the claimed technical solution is directed is to simplify the design.

The problem is solved in that the cross member of the vehicle frame, made open profile, having a horizontal part, expanding to the end surfaces and mounting holes, consists of two identical upper and lower parts of the trapezoidal profile interconnected in the middle, having expanding on both sides platforms connected to each other in the central part by a stiffener, while the platforms are made at an angle with the ends bent at the ends. In the particular case of execution, the upper and lower parts of the cross member are interconnected by means of a bolt connection or rivets.

The combination of distinctive features, namely, that the cross-member consists of two identical upper and lower parts of the trapezoidal profile interconnected in the middle, having expanding platforms on both sides, connected to each other in the central part by a stiffener, while the platforms are made at an angle ends bent at the ends, allows to simplify the design.

The essence of the utility model is illustrated by the following drawings:

FIG. 1 - Cross member of a vehicle frame, general view (rotated in isometric view);

FIG. 2 - the same, assembled on the frame (rotated in isometry).

The cross member of the vehicle frame is made of an open trapezoidal profile, has a horizontal part 1, expanding to the end surfaces and consists of two identical upper and lower parts 2 and 3 of the trapezoidal profile, which have expanding platforms 4 and 5 on both sides with holes 6 to facilitate weight due to the exclusion of "non-working" parts of the cross member. The expanding platforms 4 and 5 are made at an angle with the ends 7 and 8 bent at the ends at right angles, with holes 9 and 10 for attaching to the side members of the frame 11. At the same time, the platforms 4 of the upper part 2, which are opposite to each other, are interconnected in the central part the longitudinal stiffening rib 12 and the platforms 5 of the lower part 3 are interconnected in the central part by the longitudinal stiffening rib 13, and the upper part 2 and the lower part 3 of the cross member are symmetrically interconnected in the middle part through the holes 14 using rivets or bolted joints so that the bent the ends 7 and 8 of the platforms 4 and 5 are directed in opposite directions from each other.

The claimed technical solution allows to simplify the design.

The claimed technical solution meets the requirement of industrial applicability and is possible for implementation on standard technological equipment using previously mastered technologies.
