Description
Technical field
The utility model relates to a kind of automobile chassis frame, particularly a kind of autotruck compartment underframe.
Background technology
Autotruck compartment underframe is the vitals of autotruck, is supporting vitals such as oil cylinder and automobile bodies, is bearing various power and the moment of passing to it.Also have the usage condition of autotruck very abominable, force-bearing situation is very complicated.So require the compartment underframe that enough intensity should be arranged, for example do not have in used life gross distortion and cracking of vital parts such as underframe longeron has enough reliability and life-span to guarantee it.Existing autotruck compartment underframe (referring to Fig. 2) is mainly by component set-ups such as two ends long beam, limit longeron, intermediate longitudinal girder and main beam transverses.The limit longeron only is to adopt single girder work, and promptly the limit longeron is to be made of a longeron.Since only a longeron is arranged as the limit longeron, its insufficient strength, and in use, flexible distortion influences the normal use of vehicle, reduces vehicle life span.In addition, in the existing autotruck compartment Undercarriage structure, main beam transverse and intermediate longitudinal girder are for directly being welded to connect, and its welding quality fraction is low, rupture easily, make the repair rate height of vehicle, influence the quality of automobile.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of limit longeron intensity height is provided, is difficult for flexural deformation, main beam transverse and intermediate longitudinal girder junction are difficult for rupturing, repair rate is low and prolonged the autotruck compartment underframe of vehicle life span, has solved above-mentioned problems of the prior art.
The technical scheme that solves the problems of the technologies described above is: a kind of autotruck compartment underframe, comprise front cross rail, after cross member and 2 respectively with front cross rail, bonded assembly limit, after cross member two ends longeron, described front cross rail, also be connected with 2 intermediate longitudinal girders between the after cross member, be connected with some limit crossbeams between limit longeron and its close intermediate longitudinal girder, in the middle of also being welded with respectively, every intermediate longitudinal girder inboard strengthens channel-section steel, strengthen in the middle of 2 being connected with some intermediate transverse girders between the channel-section steel, two girder works that described limit longeron is made up of interior side girder and outer side girder, interior side girder two ends respectively with front cross rail, after cross member connects, the side girder outside in outer side girder is welded on.
Described limit crossbeam and intermediate longitudinal girder junction are provided with reinforced rib, and reinforced rib is a bending plate, and reinforced rib one side is fixed on the crossbeam of limit, and another side is fixed on the intermediate longitudinal girder.
The limit longeron that the utility model adopts adopts two girder works, and promptly the limit longeron is made up of interior side girder and outer side girder, and outer side girder is welded on the interior side girder outside, has increased the intensity of limit longeron.Guaranteed effectively that not only vehicle in use is difficult for occuring bending and deformation, prolonged the vehicle operation life-span, and adopted two girder works to improve the load carrying ability of vehicle, its load carrying ability of automobile that former load-carrying is 5 tons can be brought up to more than 8 tons.Also be provided with reinforced rib at limit crossbeam and intermediate longitudinal girder junction with the utility model, further reinforced being connected of limit crossbeam and intermediate longitudinal girder, guaranteed that limit crossbeam and intermediate longitudinal girder junction are difficult for rupturing, reduced the three guarantees repair rate of vehicle, repair rate can drop to below 0.2% from original 5%.So the utility model has improved the quality of autotruck by improving the structure of compartment underframe, has improved the market competitiveness of enterprise.
Below, the technical characterictic to the autotruck compartment underframe of the utility model is further described in conjunction with the accompanying drawings and embodiments.
Description of drawings
Fig. 1: the autotruck compartment Undercarriage structure scheme drawing of the utility model.
Fig. 2: existing autotruck compartment Undercarriage structure scheme drawing.
Among the figure: the 1-lock hook seat, the 2-after cross member, the 3-limit is in length and breadth, side girder in the 31-, the outer side girder of 32-, 4-back light permanent seat, the 5-intermediate transverse girder, 51-oil cylinder ear crossbeam, 6-limit crossbeam, 61-rear wheel cover fixed beam, 62-support compartment supporting base is strengthened channel-section steel, 8-intermediate longitudinal girder in the middle of the 7-, the 9-reinforced rib, the 10-front cross rail.
The specific embodiment
Embodiment one:
A kind of autotruck compartment underframe (referring to Fig. 1), comprise front cross rail 10, after cross member 2 and 2 respectively with front cross rail, bonded assembly limit, after cross member two ends longeron 3, described front cross rail, also be connected with 2 intermediate longitudinal girders 8 between the after cross member, be connected with 6 limit crossbeams 6 between limit longeron 3 and its close intermediate longitudinal girder 8, in the middle of also being welded with respectively, every intermediate longitudinal girder inboard strengthens channel-section steel 7, strengthen in the middle of 2 being connected with 6 intermediate transverse girders 5 between the channel-section steel, two girder works that described limit longeron 3 is made up of interior side girder 31 and outer side girder 32, interior side girder 31 two ends respectively with front cross rail 10, after cross member 2 connects, the side girder outside in outer side girder 32 is welded on, described limit crossbeam 6 is provided with reinforced rib 9 with intermediate longitudinal girder 8 junctions, reinforced rib is a bending plate, reinforced rib one side is fixed on the limit crossbeam 6, and another side is fixed on the intermediate longitudinal girder 8.
As a kind of conversion of the present utility model, the described radical that is connected limit crossbeam between limit longeron 3 and its close intermediate longitudinal girder 8, and the radical of strengthening the intermediate transverse girder between the channel-section steel in the middle of being connected 2 can increase or reduce according to the actual conditions needs.
The all limit crossbeams 6 of the utility model all are provided with reinforced rib 9 basically with intermediate longitudinal girder 8 junctions, but indivedual limit crossbeams and intermediate longitudinal girder junction, for the ease of itself and being connected yet of miscellaneous part can not being provided with reinforced rib, this individual cases can not influence whole structure of the present utility model.
Miscellaneous part of the present utility model, as lock hook seat 1, back light permanent seat 4, also have have in the crossbeam of limit as the rear wheel cover fixed beam, the conduct support compartment supporting base that has, have in the intermediate transverse girder as oil cylinder ear crossbeam, these are all identical with existing autotruck compartment Undercarriage structure, belong to known technology, repeat no more herein.
