Problems solved by technology

The traditional curb car is made of steel structure. For the steel car box, the structural strength in the above patent is good, but the overall weight is high, and the fuel consumption is high when it is empty; in order to save energy, an aluminum structure is introduced. For the aluminum carriage, although it can save energy, if the structure in the above patent is adopted, the longer the carriage is, the weaker the strength and rigidity of the carriage structure will be, and the carrying capacity will be significantly reduced

Abstract

The invention provides a plate trailer with a steel aluminum hybrid structure. The plate trailer comprises a main longitudinal girder chassis, a carriage base and a carriage lateral plate, wherein the carriage base is fixed on the main longitudinal girder chassis; the carriage lateral plate is fixed on the carriage base; the main longitudinal girder chassis has a steel structure; the carriage base and the carriage lateral plate have aluminum structures. The aluminum carriage lateral plate and the carriage base are connected with the steel main longitudinal girder chassis, so that the overall weight of the plate trailer can be reduced and the structure strength of the plate trailer can be ensured.

Description

technical field [0001] The invention relates to a railing vehicle with a steel-aluminum mixed structure. Background technique [0002] The box of a traditional panel car is connected by a vehicle chassis formed by splicing longitudinal beams and cross beams. For example, a Chinese invention patent with a publication number of CN102941886A discloses a grid-type semi-trailer box, which includes two parallel longitudinal beams. Four cross beams perpendicular to the two longitudinal beams are connected in the middle of the longitudinal beams. The cross beams and the longitudinal beams form the underframe of a semi-trailer. Perpendicular to the upper end surface of the vehicle underframe, pin holes are arranged on the upper end of the outer peripheral surface of the column, and four reaming pipes are welded on the upper end surface of each beam or longitudinal beam between two adjacent columns, and each adjacent column A sub-grid plate is arranged between the two columns, and fo...
