Front plate for semitrailer carriage body

Abstract

The invention relates to the technical field of semitrailer accessories, in particular to a front plate for a semitrailer carriage body, the front plate comprises a front plate body, an upper cross beam fixed at the upper part of the outer plate surface of the front plate body, a lower cross beam fixed at the lower part of the outer plate surface of the front plate body, and vertical beams positioned between the upper cross beam and the lower cross beam, the front plate is characterized in that the number of the vertical beams is two, and the back plate faces of the vertical beams are fixed to the outer plate face of the reinforcing base plate; the cross section of the upper cross beam is groove-shaped, or/and the cross section of the lower cross beam is groove-shaped, or/and the cross section of the vertical beams is groove-shaped; a reinforcing base plate is arranged between the upper cross beam and the lower cross beam and is fixed on the two vertical beams, and/or the reinforcing base plate is fixed on the upper cross beam and/or the reinforcing base plate is fixed on the lower cross beam. Local thickening design can be carried out on the mechanical property, so that the self weight and the material cost are reduced, and the connection strength and the performance stability are improved.

Description

technical field [0001] The invention relates to the technical field of semi-trailer accessories, and specifically relates to a front panel for a semi-trailer body that can be designed to be partially thickened in terms of mechanical properties to reduce self-weight and material costs, improve connection strength and stabilize performance. Background technique [0002] A semi-trailer is a trailer whose axle is placed behind the center of gravity of the vehicle and is equipped with a coupling device that can transmit horizontal and vertical forces to the tractor. Compared with "single-body" cars, semi-trailers can improve the comprehensive economic benefits of road transportation, the transportation efficiency can be increased by 30-50%, the cost can be reduced by 30-40%, and the fuel consumption can be reduced by 20-30%. More importantly, the use of semi-trailers can also play a certain role in promoting the organizational form of my country's logistics. [0003] The semi-tr...

Problems solved by technology

The front plate of the semi-trailer body of this type of structure makes its self-weight heavy. In order to ensure sufficient strength, the lower beam and the upper beam also use rectangular tubes. Due to the limitation of process capabilities, each tube wall of the rectangular tubes can only use the same Thick materials are not conducive to local reinforcement design in terms of mechanical properties, and the front plate body also needs thicker materials, which are heavy and unstable in performance, that is, unstable in structural strength and structural rigidity
