The invention discloses a heavy-load hydraulic axis trailer with an ultra-low platform height, and relates to a road cargo transport vehicle. The vehicle comprises a vehicle frame assembly, a steering rod system and a hydraulic suspension assembly, wherein the vehicle frame assembly comprises a central longitudinal beam, end beams and a plurality of cross beams; longitudinal edge beams are arranged between the end beams and the cross beams and between the adjacent cross beams; connecting plate assemblies are arranged at the two ends of the central longitudinal beam; the central longitudinal beam comprises a web assembly, an upper wing plate located on the top of the web assembly and a lower wing plate located on the lower portion of the web assembly. A plurality of mounting windows are formed in the web assembly corresponding to the cross beams from left to right at intervals; the steering rod system is arranged in the mounting window; the hydraulic suspension assembly is arranged at the bottom of the longitudinal edge beam; the height of the frame assembly is 650 mm; the thickness of the upper wing plate and the lower wing plate is 60 mm, and the upper wing plate and the lower wing plate are made of Q690. The height of the cargo platform surface of the vehicle is greatly reduced, and on the premise of ensuring that the overall strength of the vehicle is improved, a series of structure and use problems caused by height reduction and strength improvement of the central longitudinal beam are solved.
本发明为一种超低货台高度的重载液压轴线挂车,涉及公路货物运输车;其包括车架总成、转向杆系、液压悬挂总成,车架总成包括中央纵梁、端梁、多个横梁;端梁与横梁之间、相邻横梁之间均设置有纵边梁;中央纵梁两端设置均有连接板组件;中央纵梁包括腹板组件、位于腹板组件顶部的上翼板、位于腹板组件下部的下翼板;腹板组件对应横梁处从左到右间隔设置有多个安装窗口;转向杆系设置在安装窗口内;液压悬挂总成设置在纵边梁底部;车架总成高度为650mm;上翼板和下翼板的厚度为60mm,材质为Q690。本发明极大的降低车辆货台面高度,以保证车辆总体强度有提高为前提,解决种种因中央纵梁高度降低和强度提高而衍生出的一系列结构和使用问题。
