Abstract
A steel-pipe automobile underframe relates to an automobile underframe, particularly to an automobile underframe constructed by steel pipes. The steel-pipe automobile underframe, which is provided by the utility model, is characterized in that a plurality of straight and curved steel pipes are welded and connected, and then the underframe is formed by connecting the steel pipes, an automobile shock absorber, an axle rack, a gear box and a suspended arm device through bolts and pin shafts. The automobile underframe adopts a steel pipe structure wholly, and dozens of simple spare parts and simple forms of the steel pipes replace hundreds of complicated spare parts and complex forms of the traditional underframe; and meanwhile, low-cost cutting and bending are adopted, and simple welding replaces high-cost complex processing manners which can be only be realized by various punching, machining and electric-resistance welding equipment.
Description
Technical field
The utility model relates to a kind of automobile chassis frame, especially a kind of automobile chassis frame that adopts truss of steel tube.
Background technology
The auto trade development is the history in existing more than 100 year so far, auto manufacturing technology is making constant progress, up to the present auto body and underframe by each minute body structure metal sheet blanked part riveted joint and part welding combine, the automobile metal blanked part of this structure is various, up to more than 500.Complex-shaped, the blanked part of One's name is legion needs a large amount of pressing equipments, particular manufacturing craft, a large amount of tight and complicated welding procedure, causes that the Automobile manufacturing investment is huge, the technological process of production is complicated, vehicle body is heavier, material usage is big, cost is high.
Summary of the invention
To be solved in the utility model is exactly various by the metal sheet blanked part riveted joint automobile chassis frame parts that welding combines with part, make complicated, and the problem that automobile chassis frame is heavier provides a kind of automobile chassis frame that is all combined through bending, welding by steel pipe.
A kind of automobile steel pipe underframe of the present utility model is characterized in that it is connected and composed through bolt and bearing pin with automobile absorber, vehicle bridge frame, change speed gear box and cantilever arrangement after being welded to connect by the straight shape and the bend steel tube of some quantity.
The above-mentioned member that is welded by the straight shape and the bend steel tube of some quantity comprises steel pipe side arm, steel pipe after-frame, steel pipe girder and steel pipe limit frame; Steel pipe girder front end and the welding of steel pipe side arm, steel pipe main beam rear end and the welding of steel pipe after-frame, steel pipe girder both sides and the welding of steel pipe limit frame; Steel pipe limit frame is provided with bolt hole, is connected with change speed gear box by bolt; The steel pipe side arm is connected with bumper with bearing pin by bolt with the steel pipe after-frame; Cantilever arrangement is installed on steel pipe side arm, steel pipe after-frame with the vehicle bridge frame.
Above-mentioned steel pipe girder is welded by two steel pipes.Steel pipe is round tube or square tube, and material is carbon steel Q215, carbon steel Q235,20# steel or alloy structureal steel; The round tube diameter is φ 25～φ 52mm, and the square tube length of side is 30～60mm, and wall thickness is t2～t4.
Automobile chassis frame is whole steel-tube construction, at first, tens kinds of simple parts of steel pipe and simple shape have replaced hundreds of complicated parts of traditional underframe and complicated shape, adopt simultaneously cutting cheaply and bending, simply be welded to connect replaced that various punching press, machine original complexity, expensive add, resistance welding equipment attainable processing mode; The second, the under-carriage of same load-bearing, new steel pipe under-carriage total weight only is 2/3～3/5 of an original traditional vehicle underframe total weight; The 3rd, new steel pipe under-carriage shock resistance vibrations, antitorque vicarious loading capability are greater than traditional punching structure under-carriage of same cross-sectional; The 4th, new steel pipe under-carriage has changed traditional under-carriage cantilever shalving shape and has alleviated weight.
