The invention discloses a high-strength frame suitable for a semitrailer. The invention provides a high-strength frame suitable for a semitrailer. The high-strength frame comprises an upper frame body, a lower frame body, a tank body and a suspension support. The tank body is arranged on the upper frame, the lower frame is arranged at the bottom of the upper frame, and the suspension support is arranged at the bottom of the lower frame. An existing front frame is lengthened to serve as the upper frame, the upper frame penetrates through the whole tank body, the arrangement is better attached to the internal layout of the tank body, and stress is even. An original rear frame is replaced by an existing lower frame, the upper frame and the lower frame are connected through bolts, the suspension support is directly welded to the bottom face of the lower frame, and the cracking risk is reduced. Under the condition that the dead weight is almost not increased, the overall strength of the frame is improved; the lower frame is connected with the walking mechanism and the tank body and absorbs impact force of the walking mechanism. The frame is of a split structure, modularization is facilitated, and assembling is convenient.
本发明公开一种适用于半挂车的高强度车架。本发明提供的一种适用于半挂车的高强度车架,包括:上车架、下车架、罐体以及悬架支座;所述罐体设置在所述上车架上,所述下车架设置在所述上车架的底部,所述悬架支座设置于所述下车架的底部。将现有的前车架加长作为上车架,贯穿整个罐体,布置更贴合罐体内部布局,受力均匀;取消原来的后车架,改为现有的下车架,上车架、下车架之间用螺栓连接,悬挂支座直接焊接于下车架底面,减少开裂风险。在自重几乎未增加的情况下,使得车架的整体强度提升;下车架连接行走机构与罐体,吸收行走机构冲击力;车架采用分体式结构,有利于模块化,方便装配。
