Abstract
The utility model discloses a platform floor assembly and relates to the technical field of automobile manufacturing. The platform floor assembly comprises two longitudinal beams, a plurality of cross beams and a tipping shaft supporting frame, wherein the longitudinal beams and the cross beams are welded in a vertical and horizontal crossing form; the cross beams are horizontally arranged on the longitudinal beams through grooves formed in the longitudinal beams; the cross beams at the tails of the longitudinal beams are arranged above the middle part of the tipping shaft supporting frame. Compared with the prior art, the platform floor assembly can solve the problems of the present platform floor assembly that the structure is not reasonable enough, the present platform floor assembly is easy to break and a greater potential safety hazard is brought to the use of an automobile.
Description
Technical field
The utility model relates to field of automobile, especially a kind of automobile compartment floor assembly.
Background technology
Existing automobile bodies is the compartment of heavy motor vehicle especially, need in the time of unloading, tumble, the main shaft of its tipping device need to be through the floor pan assembly in compartment, be provided with tipping pitman bracing frame at the afterbody of floor pan assembly, as depicted in figs. 1 and 2, floor pan assembly comprises that longeron and Duo Gen crossbeam cross weld form, wherein longitudinal and cross beam cross weld place, longeron disconnects and passing for crossbeam, tipping pitman bracing frame is arranged on the lower surface of the crossbeam of base plate afterbody and the junction of longeron, and base plate afterbody crossbeam is positioned at the end face of tipping pitman bracing frame one end.Owing near tipping pitman bracing frame being stressed stronger part in carriage from overturning process, thereby shaft supporting frame one end edge that tumbles under longeron disconnection and two junctions of crossbeam of base plate afterbody and the crossbeam of base plate afterbody, be three circled in Fig. 2, the easy stressed fracture in this three place, cause floor pan assembly to damage, so that unloading bring larger potential safety hazard to compartment.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of cabin floor assembly, to solve the not rationally easily fracture of existing cabin floor assembly structure, for the use of automobile brings the problem of larger potential safety hazard.
In order to address the above problem, the technical solution of the utility model is: this cabin floor assembly comprises two longerons and Duo Gen crossbeam and the tipping pitman bracing frame of cross weld in length and breadth, described crossbeam is horizontally placed on described longeron by the groove of opening on described longeron, and the described crossbeam of described longeron afterbody is arranged at the top, middle part of described tipping pitman bracing frame.
In above-mentioned technical scheme, more specifically technical scheme can be: the described crossbeam of described longeron afterbody and the joint of described longeron are provided with brace panel.
Further: described brace panel has six, be welded on respectively the infall of the described crossbeam of described longeron and described longeron afterbody.
Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect:
This cabin floor assembly will disconnect the mode of longeron and beam welding originally, changed longeron recessing and crossbeam into through welding, had reduced the weak impact of gravity on floor pan assembly in the time tumbling of longeron fracture and beam welding intensity, and had welded brace panel to gain in strength; The crossbeam of original afterbody is changed to tipping pitman bracing frame middle top surface from tipping pitman bracing frame one end end face, and while having avoided tumbling, gravity is to the strength weak link forming between tipping pitman bracing frame one end and afterbody crossbeam.Use this cabin floor assembly, fault rate client's feedback is reduced to zero.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model embodiment is described in further detail:
This cabin floor assembly as shown in Figures 3 to 5, it comprises two longerons 1 and the Duo Gen crossbeam 2 of cross weld in length and breadth, 3 of tipping pitman bracing frames are arranged on longeron 1 in the lower surface at crossbeam 2 places of base plate afterbody, crossbeam 2 is horizontally placed on longeron 1 by the groove of opening on longeron 1, longeron 1 recessing and crossbeam 2, through welding, have reduced the weak impact of gravity on floor pan assembly in the time tumbling of longeron 1 fracture and crossbeam 2 weld strengths.The crossbeam 2 of longeron afterbody is arranged at the top, middle part of tipping pitman bracing frame 3.The crossbeam of original afterbody 2 is changed to tipping pitman bracing frame 2 middle top surface from tipping pitman bracing frame 3 one end end faces, the strength weak link of gravity to formation between tipping pitman bracing frame 3 one end and afterbody crossbeam 2 while having avoided tumbling.The crossbeam 2 of longeron afterbody and the joint of longeron 1 are provided with brace panel 4.Brace panel 4 has six, is welded on respectively the infall of the crossbeam 2 of longeron 2 and longeron afterbody, to gain in strength.
Claims (3)
1. a cabin floor assembly, comprise two longerons and Duo Gen crossbeam and the tipping pitman bracing frame of cross weld in length and breadth, it is characterized in that: described crossbeam is horizontally placed on described longeron by the groove of opening on described longeron, the described crossbeam of described longeron afterbody is arranged at the top, middle part of described tipping pitman bracing frame.
2. cabin floor assembly according to claim 1, is characterized in that: the described crossbeam of described longeron afterbody and the joint of described longeron are provided with brace panel.
3. cabin floor assembly according to claim 1 and 2, is characterized in that: described brace panel has six, is welded on respectively the infall of the described crossbeam of described longeron and described longeron afterbody.
