In technique scheme, more specifically scheme can also be: the two ends on rear side of described cross-tie beam are respectively arranged with two vertical beams, is provided with a spreader in the upper end of described vertical beam; The lower end of the described spreader outside described vertical beam is provided with hangers, the inner side of the described long camber beam in the rear between second of portion's vehicle frame described horizontal strength beam and the 3rd described strength beam is provided with described hangers, the lower end of first described horizontal strength beam of described rear frame is provided with described hangers, and the main beam transverse lower end of the described longeron one end be connected with described short camber beam is provided with described hangers.
Further: be provided with underframe in the bottom of described two long beams and two main beam transverses, described underframe is welded by two long angle steel and two angle clips; Polylith base plate is provided with between two described long angle steel; Described underframe is connected with described main beam transverse and described long beam respectively by polylith adapter plate.
Further: between described cross-tie beam, to be provided with a brace panel; The supporting plate of two " L " shapes is provided with between rear two described strength beams.
Owing to have employed technique scheme, compared with prior art, the beneficial effect had is in the present invention:
Because vehicle frame is divided into front frame and rear frame, they are connected by longeron, so, the weight saving of vehicle frame; Again because be provided with many crossbeams, so the intensity of vehicle frame is guaranteed, and on vehicle frame, leave the place of laying storage battery, complete vehicle weight can not be caused unbalanced.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the upward view of Fig. 1.
