The off-highway dumper ring beam structure comprises an upper ring beam, a middle supporting body and a lower ring beam which are combined, the upper ring beam, the middle supporting body and the lower ring beam form an integral box-shaped closed structure together with a frame longitudinal beam, the integral box-shaped closed structure is O-shaped, the upper ring beam is connected with the middle supporting body through bolts, the middle supporting body is nested on the frame longitudinal beam, and the lower portion of the middle supporting body is welded to the lower ring beam; the upper ring beam is of a box type welding structure and is detachable, the rigidity of the upper portion of the ring beam is improved, meanwhile, a power assembly is convenient to install and maintain, the middle supporting body and the lower ring beam are integrally embedded in the downward inclined face of the frame main longitudinal beam, the center of gravity of the front end of a vehicle can be lowered, the frame main longitudinal beam does not need to be broken, and the cracking risk is greatly reduced. Meanwhile, the functions of a front suspension cylinder support, a front steering axle transverse pushing seat, a vehicle body system, a walking board support and the like are integrated, the process is simple, cost is low, rigidity and strength are good, and manufacturing efficiency is high.
本发明公开了非公路自卸车圈梁结构,包括组合而成的上圈梁、中间支撑体及下圈梁,同车架纵梁一起组成整体箱型封闭结构,形状似字母O型,上圈梁与中间支撑体采用螺栓连接,中间支撑体嵌套在车架纵梁上,中间支撑体下部与下圈梁焊接;上圈梁为箱型焊接结构并设置为可拆卸,提升圈梁上部刚度的同时方便动力总成安装及维修,中间支撑体及下圈梁整体镶嵌在车架主纵梁向下倾斜面上,可降低车辆前端重心,车架主纵梁无需断开,大大降低开裂风险;同时集成前悬挂缸支座、前转向桥横推座、车身系统及走台支撑等功能于一体,工艺简单、成本低、刚度和强度好,制造效率高。
