The invention discloses a high-strength large-volume self-dumping semitrailer carriage, which consists of a front part, a rear part, side parts and a bottom part. The bottom part comprises a bottom plate, longitudinal beams for supporting the bottom plate and a plurality of cross beams connected with the longitudinal beam. The longitudinal beams are of a two-longitudinal-beam structure composed oftwo inner longitudinal beams or a four-longitudinal-beam structure composed of two inner longitudinal beams and two outer longitudinal beams. Each side part comprises a side plate and an upper longitudinal beam for supporting the side plate. Each inner longitudinal beam is of a pi-shaped structure with an upward protruding part, and the side plates are arranged to be of folded outward-expanding structures with outward protruding parts so as to increase the capacity. The bottom plate is supported by the pi-shaped longitudinal beams, so that the rigidity requirement of the bottom plate is met,and the height of the bearing surface is effectively reduced. Due to the fact that the side plates are arranged to be of the folded outward-expanding structures with outward protruding parts, the protruding parts can increase the volume of the carriage.
本发明公开了一种高强度大容积自卸半挂车车厢,其中,由前部、后部、侧部和底部组成:所述底部包括:底板、支撑底板的纵梁和连接纵梁的若干横梁;所述纵梁为由两根内纵梁组成的两纵梁结构,或由两根内纵梁和两根外纵梁组合形成的四纵梁结构;所述侧部包括:侧板和支撑侧板的上纵梁;其中,所述内纵梁为具有向上凸部的π字型结构,所述侧板设置为具有向外凸出部的折型外涨结构以增加容量。本发明的底板采用π字型纵梁支撑,不但满足了底板的刚度需求,且有效地降低了承载面高度。通过将侧板设置成向外凸出部的折型外涨结构,凸出部能够增加车厢的容积。
