Description
Technical field
The present invention relates to a kind of fuel tank.
Background technology
For effectively reducing dead weight of vehicle, improve fuel economy, satisfy state IV engine common rail system to the requirement of fuel qualities and container cleanliness factor thereof, the utilization of Al-alloy metal fuel tank on truck is increasingly extensive.
Traditional aluminum alloy internal partition is fixed on the fuel tank cylindrical shell by welding manner.Yet, because aluminum alloy materials has that permeability of heat is good, heat absorption capacity and the characteristics such as linear expansion coefficient is large, fusing point low and hot strength is little, in when welding, be subjected to the impact of ambient temperature, humidity and operator's weld horizontal, the defective such as careless slightlyly material oxidation, pore will occur, burn.Owing to have weld defect, so the phenomenon that internal partition comes off in use appears in fuel tank easily, thereby had a strong impact on the Rigidity and strength of aluminum alloy fuel tank assembly.Particularly when tank assembly is subject to external impacts, because fuel tank has lost inner support, thus the faults such as fuel tank distortion, cracking very easily appear, thus caused great potential safety hazard.
Summary of the invention
The present invention is intended to overcome the problems referred to above and a kind of fuel tank is provided, and the internal partition of this fuel tank can be securely fixed on the cylindrical shell.
To achieve these goals, the invention provides a kind of fuel tank, this fuel tank comprises cylindrical shell and is arranged in the internal partition of this cylindrical shell, wherein, the connecting bridge that described internal partition has base portion and is bent to form from the periphery of this base portion, described cylindrical shell is captiveed joint by the mode of force fit with described connecting bridge.
Preferably, be formed with the first groove on the described cylindrical shell, be formed with the second groove on the described connecting bridge, described the first groove embed in described the second groove and with described the second groove force fit.
Preferably, described the first groove and the second groove are respectively a plurality of, and these a plurality of first grooves and the second groove be circumferentially spaced apart along described internal partition respectively.
Preferably, described the first groove and the second groove are the Long Circle groove.
Preferably, the breadth depth ratio of described the first groove and the second groove is 3: 1～6: 1.
Preferably, described the first groove and the second groove are by forming at the described cylindrical shell of the outside of described cylindrical shell punching press.
Preferably, described the first groove and the second groove form by punch ram.
Preferably, described internal partition is three, and these three internal partitions are spaced apart along the length direction of described cylindrical shell.
Preferably, be formed with opening on the described base portion.
Preferably, described internal partition and cylindrical shell are made by aluminum alloy materials.
Because the cylindrical shell of fuel tank provided by the invention is captiveed joint by the mode of force fit with internal partition, so internal partition can be securely fixed on the cylindrical shell, thereby avoided the generation of internal partition obscission in the fuel tank use procedure, guaranteed the powerful support of internal partition to tank assembly, thereby improved the Rigidity and strength of tank assembly, avoided having eliminated potential safety hazard owing to tank assembly is subject to the phenomenons such as fuel tank distortion that external impacts produces, cracking.In addition, fuel tank provided by the invention is made easily, and with low cost.And, because the first groove can illustrate the installation site of fuel tank clearly to the assembler, so effectively improved efficiency of assembling and the assembly quality of fuel tank on vehicle.
Other features and advantages of the present invention will partly be described in detail in the specific embodiment subsequently.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is elaborated.Should be understood that the specific embodiment described herein only is used for description and interpretation the present invention, is not limited to the present invention.
As shown in Figure 1 to Figure 3, the invention provides a kind of fuel tank, this fuel tank comprises cylindrical shell 2 and is arranged in the internal partition 1 of this cylindrical shell 2, wherein, the connecting bridge 9 that described internal partition 1 has base portion 8 and is bent to form from the periphery of this base portion 8, described cylindrical shell 2 is captiveed joint by the mode of force fit with described connecting bridge 9.
Particularly, as shown in Figures 2 and 3, can be formed with the first groove 3 on the described cylindrical shell 2, can be formed with the second groove 10 on the described connecting bridge 9, described the first groove 3 embed in described the second groove 10 and with described the second groove 10 force fits.
Described the first groove 3 and the second groove 10 can be one, also can be for a plurality of.Formation for convenient the first groove 3 and the second groove 10, and internal partition 1 equilibrium is fixed on the cylindrical shell 2 reliably, preferably, described the first groove 3 and the second groove 10 are respectively a plurality of, and these a plurality of first grooves 3 and the second groove 10 be circumferentially spaced apart along described internal partition 1 respectively.
Described the first groove 3 and the second groove 10 can be the groove of various shapes, for example square groove, circular groove, oval-shaped groove or Long Circle groove.For convenient processing, preferably, described the first groove 3 and the second groove 10 are the Long Circle groove.The first groove 3 and the second groove 10 can possess suitable breadth depth ratio.When the first groove 3 and the second groove 10 were the Long Circle groove, the breadth depth ratio of described the first groove 3 and the second groove 10 can be 3: 1～6: 1.
The first groove 3 and the second groove 10 can take various suitable modes to form, and for example, described the first groove 3 and the second groove 10 can be by forming at the described cylindrical shell 2 of the outside of described cylindrical shell 2 punching press.The first groove 3 and the second groove 10 can take various proper implements punching presses to form, and for the processing of convenient the first groove 3 and the second groove 10, preferably, described the first groove 3 and the second groove 10 form by punch ram.The technique of punching press the first groove 3 and the second groove 10 is conventionally known to one of skill in the art on punch press, does not repeat them here.
Internal partition 1 can be various suitable shapes, for example peviform.The number of internal partition 1 can suitably be selected, and generally, described internal partition 1 is three, and these three internal partitions 1 are spaced apart along the length direction of described cylindrical shell 2.
