Abstract
The utility model discloses a lightweight semitrailer longeron, including last airfoil, web under, the force -bearing point who goes up the airfoil widens, lower airfoil and last airfoil to add the wide section bit width the same, the gooseneck department of web adopts the reinforcement that appears of middle trapezoidal reinforcement, both ends L. This structure than traditional structure under the same situation of bearing, strengthened the bearing capacity of longeron, weight alleviates about 80 kilograms altogether.
Description
Technical field
The utility model relates to semi-trailer longitudinal beam field, specifically belongs to a kind of light semitrailer longitudinal beam.
Background technology
Left-right longeron is one of the major part in superimposed trailer structure, its welding quality and bulk strength property relationship to complete vehicle structure stability, resist intensity and the problem in service life.Therefore the various aspects of performance index impacts of superimposed trailer superimposed trailer in-use performance.
Utility model content
The purpose of this utility model is to provide a kind of light semitrailer longitudinal beam, and this structural rate conventional confguration, under same bearer situation, enhances the load-carrying capacity of longeron, and weight alleviates about 80 kilograms altogether.
The technical solution of the utility model is as follows:
A kind of light semitrailer longitudinal beam, include top airfoil, lower aerofoil, web, the force part of top airfoil is widened, and lower aerofoil is identical with the those widened sections bit width of top airfoil, and the gooseneck place of web adopts middle trapezoidal reinforcing, two ends L shape is reinforced.
Described top airfoil, lower aerofoil, web adopt the high strength material of more than T610.
The utility model top airfoil adopts not wide symmetric design, and stressed larger portion position is widened with lower aerofoil wide; Lower aerofoil adopts wide symmetric design; Web adopts local strengthening, and stressed weak part gooseneck place adopts unique reinforcement mode, middle trapezoidal reinforcing, and two ends L-type is reinforced; This structural rate conventional confguration is under same bearer situation, and weight alleviates about 80 kilograms altogether.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
See accompanying drawing, a kind of light semitrailer longitudinal beam, include top airfoil 1, lower aerofoil 2, web 3, the force part of top airfoil 1 is widened, lower aerofoil 2 and top airfoil 1 to widen position 4 width identical, trapezoidal 5 to reinforce in the middle of the gooseneck place of web 3 adopts, two ends L shape 6 reinforce.Top airfoil, lower aerofoil, web adopt the high strength material of more than T610.
