The invention belongs to the technical field of automobile manufacturing, and discloses a semitrailer frame which comprises two girders arranged in a spaced mode and a cross beam connected with the two girders, the semitrailer frame further comprises two middle rotary clamping and locking parts, and the two middle rotary clamping and locking parts are detachably fixed to the two girders through threaded connecting pieces respectively. Compared with the prior art, the semitrailer frame has the advantages that two locking positions capable of being connected with a carriage body are formed; each middle rotary clamping and locking part is fixed to the side portion of the girder, and the structure facilitates the assembling and maintaining of the middle rotary clamping and locking parts. The girders keep a complete structure all the time, the strength and rigidity of the girders are not affected, and the overall mechanical property of the frame can be improved. In addition, by designing the specific structure of the middle rotary clamping and locking parts, effective and stable connection is achieved, meanwhile, the weight of components is reduced, and light weight of the whole vehicle is facilitated.

    本发明属于汽车制造技术领域,公开了一种半挂车车架,包括:间隔设置的两个大梁,连接两个所述大梁的横梁,所述半挂车车架还包括中部旋转卡锁部,所述中部旋转卡锁部为两个,分别通过螺纹连接件可拆卸固定于两个所述大梁上。与相关技术相比,本发明一种半挂车车架中,形成可与厢体相连的两处锁紧位置。每个所述中部旋转卡锁部分别固定在大梁侧部,该结构利于所述中部旋转卡锁部的组装和维修。本发明中的大梁始终保持着完整的结构,其强度刚度不受影响,利于提高车架的整体力学性能。此外,本发明通过设计具体的中部旋转卡锁部的结构,实现有效稳固连接的同时,减轻了构件的重量,利于整车的轻量化。
