Abstract
The utility model discloses a space steel tube member bearing vehicle frame, which is composed of a plurality of steel pipes of different outside diameters and wall thicknesses, a plurality of steel pipe elbows which are bent with uniform section and a plurality of saddle heads which are composed of saddle-shaped surfaces and pipe joints. A pipe joint is welded with a steel pipe or a steel pipe elbow together, and a saddle-shaped surface and the side wall of the other steel pipe are welded together. The stamping and welding of a large quantity of moulds in the traditional technology can be eliminated, a vehicle frame does not need carrying out anti-corrosive painting, and thus, production process is simplified and the efficiency of designing and developing novel vehicle model is enhanced. The utility model is suitable for most automobiles of different styles and use in middle and small sizes.
Description
The utility model relates to a kind of vehicle frame of auto body, specifically a kind of spatial bearing steel-pipe frame.
Orthodox car is in automobile body manufacture process, often to combine reaching 350 to 500 metallic stamping pieces, this process must need a large amount of pressing equipments, particular manufacturing craft, a large amount of accurate welding jigs and complicated welding robot (manipulator) and finish, and also must comprise a special quality anticorrosive coating line simultaneously.Adopt behind this vehicle body investment of Automobile manufacturing huge, technological process of production complexity, new model comes out and needs course through very long from being designed into product, thereby the automobile industry development of developing country is caused great difficulty and restriction.
The purpose of this utility model is to provide a kind of vehicle body frames that can make a large amount of module punching presses welding in the abandoning tradition technology in the Automobile manufacturing process and complicated anticorrosive coating, thereby can simplify the production technology of automobile greatly.
For achieving the above object, vehicle body frames of the present utility model is whole to be the saddle joint composition of some quantity steel pipes, the bending some quantity steel elbows of uniform cross section and some quantity with several various outer diameters and wall thickness; Described saddle joint is made of a saddle type surface and an interface tube, forms several different angles between described saddle type surface and interface tube; Described interface tube and an above-mentioned steel pipe or steel elbow weld together, described saddle type surface then with another steel pipe sidewall weld together.
Steel pipe described in the such scheme is a stainless steel tube, and described elbow also is bent to form through uniform cross section by stainless steel tube, between described interface tube and steel pipe or elbow by argon shield weldering weld together, between described saddle type surface and steel pipe sidewall then by the soldering weld together.
The quantity of described steel pipe, elbow and saddle joint can change according to the different of vehicle.
Owing to adopted technique scheme, the big position of load and relative stress in the vehicle frame, as the steel pipe with big external diameter and wall thickness such as chassis, doorframe, the steel pipe of then available less external diameter and wall thickness at other position, the vehicle frame of whole spatial structure connects by the part plan between steel pipe, the bending elbow of uniform cross section and the saddle joint to be realized, makes simple and convenient; The carrying of vehicle body then realizes by framework, thereby in whole Automobile manufacturing process, broken traditional natural mode, save a large amount of module punching press welding in the traditional handicraft, also needn't carry out anticorrosive coating to vehicle frame, so not only energy-conserving and environment-protective, production technology is simplified greatly, low dropped into, also can produce on a small scale high-quality, automobile product cheaply, and improved design, the development efficiency of trendy vehicle; The utilization of this vehicle frame simultaneously can be the appearance and the interior material diversification utilization of vehicle body and has expanded a space widely, it can utilize lighter, more facile material especially composite material realize.
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail.
Fig. 1 to Fig. 4 is respectively front view, birds-eye view, right elevation and the left view of a vehicle frame of the utility model;
Fig. 5 is the partial enlarged drawing of saddle joint among Fig. 3.
As shown in the figure, this vehicle frame is the vehicle frame of Cars, be 33 stainless steel tubes 1 with 2 kinds of external diameters (2.5 inches, 3 inches) and 5 kinds of wall thickness (1mm, 1.2mm, 1.5mm, 2mm, 2.5mm), bending 35 steel elbows 2 of uniform cross section and 22 saddle joints 3 are formed; Saddle joint 3 is made of a saddle type surface 4 and an interface tube 5.When making vehicle frame, according to styling design among the figure, configuration steel pipe 1 and steel elbow 2 on the relevant position.After then the interface tube 5 of saddle joint 3 being injected a steel pipe 1 or steel elbow 2; weld them together with the argon shield weldering; saddle type surface 4 usefulness solderings with saddle joint 3 are welded on another sidewall that needs bonded assembly steel pipe 1 again; thereby part plan welding together by steel pipe 1, steel elbow 2 and saddle joint 3; steel pipe 1, steel elbow 2 are combined by saddle joint 3, realize that the solid of whole vehicle frame is made.The position big in load, that stress is big, as frame chassis, car door place, adopting external diameter is that 3 inches, wall thickness are the steel pipe 1 of 2.5mm, and at the less positions of other stress such as roof or positions, vehicle body front, and then can adopt external diameter is that 2.5 inches, wall thickness are the steel pipe 1 of 1mm, 1.2mm or 1.5mm.(8 kinds of angles are arranged in this example, and as shown), steel pipe 1 and steel elbow 2 are at the needs of diverse location, angle when connecting to adapt to whole vehicle frame to form several different angles between the saddle type surface 4 of 22 saddle joints 3 and the interface tube 5.When vertically connecting as 1 need of steel pipe, 5 of saddle type surface 4 and interface tubes meet at right angles, and when 1 of steel pipe (or steel elbow 2) needs oblique connection, then can become different acute angles (obtuse angle) between saddle type surface 4 and the interface tube 5.Soldering is to carry out under the lower state of temperature, and is indeformable when the integral solder to guarantee framework.The gross weight of this vehicle frame is 130Kg only, to save than the automobile of routine over half, and can be such as the corrosion protection of electrophoretic coating one class.
To different automotive types, the quantity of used steel pipe, elbow and saddle joint can be different, and the external diameter of steel pipe, the kind of wall thickness also can be different, and the vehicle frame shape that is combined into also changes because of the difference of vehicle configuration, purposes.In the application process of reality, also can adopt the steel pipe of other material or other kind to wait the stainless steel material that replaces in the foregoing description.
The utility model is applicable to the automobile of most of medium and small different styles and purposes.
