A kind of plane skeleton structure cargo floor assembly
Technical field
The utility model relates to a kind of design processing technique field of automobile component, is exactly the improvement of cargo floor structure in more detail.
Background technology
Cargo floor assembly of the prior art, its container crossbeam is placed on the top of container longeron by connecting panel, and the termination of container frame and crossbeam joins, and the three forms the superimposed type mesh skeleton.Cargo floor is positioned on this skeleton, links to each other with skeleton by the connection mode of welding, and forms the single-piece carrying platform.This carrying platform adopts U-bolt, chock, connecting panel to link to each other with the chassis side rail on chassis.
Above-mentioned cargo floor assembly structure is simple, easy to manufacture, but relatively deadweight, and it is less than normal to the contribution of the rigidity of car load and intensity, forces vehicle frame to strengthen rigidity and intensity, thereby has restricted the car load lightweight to a great extent.Along with implementing in full of weight metering charging, from saving energy and reduce the cost, observe rules and obey laws and reducing many-sided demand such as traffic cost and consider, the conventional confguration container urgent need of conduct oneself with dignity bigger is carried out bigger change.
Summary of the invention
The purpose of this utility model is under the prerequisite that guarantees vehicle integrated carrying ability, reduces the curb mass of vehicle, reduces the height of gravitational center of vehicle, has carried out brand-new design with the cargo floor assembly of goods carrying vehicle and with the connection mode of vehicle frame.Plane described in the utility model skeleton structure cargo floor assembly has from heavy and light, stiffness greatly, supports car load weight-saving characteristics.
Plane described in the utility model skeleton structure cargo floor assembly mainly is made up of cargo floor skeleton and cargo floor two parts, also comprises being connected of cargo floor and chassis side rail.Specifically, be exactly plane described in the utility model skeleton structure cargo floor assembly, its cargo floor skeleton mainly is made up of container longeron, container crossbeam, cargo floor, container frame.The container crossbeam can be horizontally through the container longeron, also can butt up against the web of container longeron.The container crossbeam has formed cross one another plane net structure by welding with the connecting panel that is riveted on the container longeron.
Cargo floor preferably adopts corrugation form height strength structure, places on the base plate skeleton, by the connection mode of welding and the integral body of cargo floor skeleton formation rigidity, common carrying.Container can pass through connecting panel, U-bolt links to each other with the chassis side rail on chassis.The connection structure of described container and chassis side rail also can replace with other connection mode, as: tiltedly draw supporting construction 15 shown in the accompanying drawing 3, or vertical connection structure 14; Or U-bolt 9, connecting panel 13, tiltedly draw the combination of supporting construction 15, vertical connection structure 14.
The utility model is avoided and has been overcome the deficiencies in the prior art and shortcoming, skeleton in the cargo floor assembly adopts plane skeleton structure form, cancelled the chock structure in traditional connection structure, and under the prerequisite that guarantees the wheel bounce space, appropriateness has increased the height of container longeron.Not only improve intensity, rigidity and the weight degree of utilization of main bolster, and can reduce the curb mass and the vehicle's center of gravity of vehicle effectively, widened the bearing space of vehicle, improved the riding stability of vehicle.Cargo floor adopts corrugation shape and is connected as a single entity with plug welding form and skeleton, has improved the strength and stiffness of floor pan assembly.Adopt the leak-tight joint mode between container and the vehicle frame, can bring into play the overall performance of container and vehicle frame better.

With reference to Fig. 1, existing automobile container floor pan assembly, its container crossbeam 1 is placed on the top of container longeron 2 by connecting panel 3, and container frame 7 joins with the termination of crossbeam 1, and the three forms the superimposed type mesh skeleton.Cargo floor 6 is positioned on this skeleton, links to each other with skeleton by the connection mode of welding, and forms the single-piece carrying platform.This carrying platform adopts U-bolt 9, chock 4, connecting panel 5 to link to each other with the chassis side rail 8 on chassis.
The specific embodiment
Embodiment 1.
With reference to Fig. 2 .1, plane described in the utility model skeleton structure cargo floor assembly, its cargo floor skeleton mainly is made up of container longeron 2, container crossbeam 1, cargo floor 11, container frame 12.Container crossbeam 1 is horizontally through container longeron 2.Container crossbeam 1 has formed cross one another plane net structure by welding with the connecting panel 10 that is riveted on the container longeron.
Cargo floor 11 adopts corrugation form height strength structure, places on the base plate skeleton, by the connection mode of welding and the integral body of cargo floor skeleton formation rigidity, common carrying.
Container links to each other with the chassis side rail 8 on chassis by connecting panel 13, U-bolt 9.Described container can replace with other connection mode with being connected also of chassis side rail, as: vertical connection 14 structures shown in Figure 3, or connecting panel 13 structures shown in Figure 4, or shown in Figure 5 tiltedly drawing support 15 structures, or U-bolt 9, connecting panel 13, tiltedly draw the combination of supporting construction 15, vertical connection structure 14.
Embodiment 2
With reference to Fig. 2 .2, except container crossbeam 1 butted up against the web of container longeron 2, other was with embodiment 1.
Plane described in the utility model skeleton structure cargo floor assembly, avoid and overcome the deficiencies in the prior art and shortcoming, skeleton in the cargo floor assembly adopts plane skeleton structure form, cancelled the chock structure in traditional connection structure, and under the prerequisite that guarantees the wheel bounce space, appropriateness has increased the height of container longeron.Not only improve intensity, rigidity and the weight degree of utilization of main bolster, and can reduce the curb mass and the vehicle's center of gravity of vehicle effectively, widened the bearing space of vehicle, improved the riding stability of vehicle.Cargo floor adopts corrugation shape and is connected as a single entity with plug welding form and skeleton, has improved the strength and stiffness of floor pan assembly.Adopt the leak-tight joint mode between container and the vehicle frame, can bring into play the overall performance of container and vehicle frame better.
The utility model describes with reference to drawings and Examples; but protection domain is not limited thereto; in the utility model technical scope, have those of ordinary skill and can pass through simple conversion, and obtain the same technique effect of the utility model, equally in protection domain of the present utility model.
