A semitrailer is a trailer whose axle is located behind the center of gravity of the vehicle and is equipped with a coupling device that transmits horizontal and vertical forces to a tractor, and is a heavy transport vehicle that is connected to the head of the semitrailer by means of a kingpin. Compared with a single automobile, the semitrailer can improve the comprehensive economic benefit of road transportation, the transportation efficiency can be improved by 30-50%, the cost is reduced by 30-40%, and the oil consumption is reduced by 20-30%. More importantly, the semitrailer can also play a certain promoting role in the organization form of logistics in China.
The semitrailer in the prior art has the disadvantages that the self weight is large and the increase of cargo transportation weight is not facilitated due to the structure of the accessories.
Referring to the attached drawing 1, the suspension bracket connecting structure for the semitrailer in the prior art comprises a suspension bracket (1), a frame longitudinal beam (3) fixed at the top end of the suspension bracket (1), a frame cross beam (2) fixed on the frame longitudinal beam (3), and a connecting pipe beam (4) fixed at the lower part of the suspension bracket (1), wherein the outer wall surface of the connecting pipe beam (4) is welded with the lower plate surface of the frame cross beam (2) into a whole through a reinforcing plate (5). The suspension support connecting structure for the semitrailer with the structure enables the suspension support to have large dead weight, in order to guarantee enough strength, the suspension support (1) and the frame longitudinal beam (3) need thick material processing, generally more than 6mm, and the suspension support has large weight and unstable performance, namely, the lateral structural strength or the rigidity is unstable.
SUMMERY OF THE UTILITY MODEL
Aiming at the defects in the prior art, the utility model provides the suspension bracket connecting structure for the semitrailer, which improves the connecting strength, reduces the weight and has stable performance.
In order to solve the technical problems, the utility model adopts the following technical scheme:
a suspension support connecting structure for a semitrailer comprises a suspension support, a frame longitudinal beam fixed at the top end of the suspension support, a frame cross beam fixed on the frame longitudinal beam, and a connecting pipe beam fixed at the lower part of the suspension support; wherein: a reinforcing plate is arranged between the frame cross beam and the connecting pipe beam, the reinforcing plate also comprises a web plate and a reinforcing rib plate positioned on the front plate surface of the web plate, the reinforcing rib plate and the web plate are fixed into a whole, and a notch is formed in the web plate;
the rear plate surface of the reinforcing plate is fixed with the outer plate surface of the suspension support to form a whole, the top plate surface of the reinforcing plate is fixed with the bottom plate surface of the frame cross beam and/or the bottom plate surface of the frame longitudinal beam to form a whole, and the bottom plate surface or the side plate surface of the reinforcing plate is fixed with the outer wall surface of the connecting pipe beam to form a whole.
Due to the structure, the connecting strength is improved, the self weight is reduced, and the performance is stable.
