Description
Technical Field
The utility model relates to a car crossbeam field especially relates to an integral cast hollow structure commercial car crossbeam.
Background
At present, the mode of manufacture of commercial car crossbeam on the market is mostly the steel sheet punching press mode, needs a plurality of spare parts to pass through bolt/rivet connection, and a plurality of spare parts need many sets of mould manufacturing, and it is more to make required manpower, man-hour, and manufacturing efficiency is low, leads to whole manufacturing process complicated. And the strength of the cross beam of the stamping structure is low, and when the commercial vehicle is overloaded seriously or runs under the condition of bad road conditions, the torsion caused by bumping of the vehicle can cause the torsional deformation of the cross beam and even the fracture of the cross beam. And a few of the casting methods adopt an integral casting method, but the product quality is heavy, and the automatic production is difficult to realize.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an integral cast hollow structure commercial car crossbeam is in order to solve above-mentioned technical problem.
The utility model discloses a solve above-mentioned technical problem, adopt following technical scheme to realize: the cross beam of the commercial vehicle with the integrally cast hollow structure is connected with a first side wing plate and a second side wing plate in a transitional mode, the first side wing plate and the second side wing plate are symmetrical about the center line of the hollow tubular structure, a first arrangement boss and a second arrangement boss extend from the upper side of the hollow tubular structure, and a first arrangement supporting leg and a second arrangement supporting leg are arranged in the middle of the hollow tubular structure.
Preferably, the hollow tubular structure and the first and second arrangement legs form a U-shaped opening.
Preferably, the first side wing plate and the second side wing plate are both provided with bolt holes connected with bolts.
Preferably, a first rod connecting boss and a second rod connecting boss are arranged on a vertical plane of the hollow tubular structure between the first side wing plate and the second side wing plate.
Preferably, the first and second arrangement legs are in the shape of flat ear mounts for attachment to a backing plate of a frame rail.
The utility model has the advantages that:
the utility model discloses in, the truck crossbeam in this scheme adopts integrative casting, and present big automated production in batches reduces product weight, practices thrift manufacturing cost, wherein through arranging the landing leg, connects solebar's welt or directly is connected with balanced suspension, improves frame and balanced suspension's intensity, arranges the boss through tubular structure's both sides for the boss that the V pole is connected, through the different positions of adjustment boss, satisfies bridge connection position demand behind the different motorcycle types.
