Embodiment 1

[0022] Example 1, see figure 1 , 2 , 3, 4, 5, 6, 7, 8, 9, 10, 11, according to the design requirements, all components are made of high-strength steel plates, and the upper wing plate 8 and the lower wing plate 10 are processed, and the width and thickness of the two are not equal A web 9 with a corrugated cross-section is made by bending, stamping or rolling, and the above-mentioned upper wing 8, lower wing 10 and web 9 are welded or riveted into an I-shaped frame longitudinal beam 6 , the web 9 uses corrugation to increase the strength of the frame longitudinal beam 6 in the vertical direction between the upper wing plate 8 and the lower wing plate 10; the vehicle frame assembly 2 is formed by two pieces of vehicle frame longitudinal beams 6 and related beams Lay the bottom plate 7 of the car frame on the frame assembly 2 to form the bottom plate assembly of the car frame to carry goods. Car box assembly 1 is installed on the base plate 7, so that loading goods is more con...

Abstract

The invention discloses a light-weight semitrailer, which comprises a compartment assembly (1), a rack assembly (2), a tool kit (3), a semitrailer supporting device (4) and a suspension brake and lighting system (5). The light-weight semitrailer is characterized in that a frame longitudinal beam (6) of the rack assembly (2) consists of an upper wing plate (8), a web (9) and a lower wing plate (10), wherein the rack assembly (2) is provided with a compartment bottom plate (7) to form a rack bottom plate assembly; the compartment bottom plate (7) is provided with the compartment assembly (1); a plurality of components on the compartment assembly (1) and the rack assembly (2) adopt a corrugated structure; the tool kit (3), the semitrailer supporting device (4) and the suspension brake and lighting system (5) are arranged below the rack bottom plate assembly; more places on a compartment and a frame adopt the corrugated structure and high-intensity steel plates so as to achieve a purpose that the curb weight of the semitrailer is lowered under the condition that the vehicle load bearing capability is not lowered, and the light-weight design of the semitrailer is realized. Compared with the traditional semitrailer, the light-weight semitrailer disclosed by the invention is characterized in that weight is lowered by about 18%, and the light-weight semitrailer is accelerated to develop.

Description

Technical field: [0001] The invention relates to the technical field of trailers, in particular to a lightweight semi-trailer. Background technique: [0002] Most of the semi-trailers currently in operation are designed and manufactured under overload conditions. They are characterized by large curb weight. This type of semi-trailer seriously affects the actual loading quality and cannot meet the needs of the market. According to the data provided by the Aluminum Industry Association, for semi-trailer trains, in general, for every 10% reduction in the mass of the car, its fuel consumption can be reduced by 6% to 8%, that is, for every 1000kg of mass reduction, every 100km 0.6 liters of fuel is saved, and the CO2 emission can be reduced by about 5g / km for every 100kg weight reduction of the car. The maximum total mass of the semi-trailer is 40,000kg. Assume that the annual mileage of the semi-trailer train is 100,000km, of which the empty vehicle travels 20,000km. If the cur...
