CONNECTING STRUCTURE OF LANDING LEGS AND CROSSBEAMS AND SEMITRAILER USING SAME

摘要

A connecting structure of landing legs and crossbeams comprises a pair of landing leg connecting supports (3). An outer side of each landing leg connecting support (3) is connected to an inner side of an upper portion of a landing leg (1) of a semitrailer frame. An inner side of each landing leg connecting support (3) is connected to an outer side of a crossbar (5) of the semitrailer frame. An upper portion of each landing leg connecting support (3) is connected to a lower portion of a main crossbeam (2) of the semitrailer. Lower portions of the landing leg connecting supports (3) are connected to each other by a supporting crossbeam (4) that is parallel to the main crossbeam (2) to form a closed-loop structure. Thereby, a closed-loop force transmission path is formed, which improves the force bearing condition of the semitrailer frame and provides a more compact structure and more pleasing appearance.
