In order to solve the problems of the technologies described above, the utility model provides a kind of rigidity oil pipe, and wherein, described rigidity oil pipe comprises tubular body, and the tube wall of described tubular body has fold, and the inside of described fold is formed with the cavity with described tubular body internal communication.
Preferably, described fold shape becomes projection radially and/or the depression along described tubular body.
Particularly, described fold shape becomes ripple struction and has outwards outstanding crest and inside recessed trough.
Preferably, described fold forms rounding off at described crest and trough place.
Preferably, at least one end of described tubular body is provided with sealing configuration.
Preferably, described sealing configuration forms annular protrusion.
Particularly, the outer surface of described annular protrusion is the form seamlessly transitting.
Preferably, described tubular body and described fold are integrally formed.
The utility model also provides a kind of wheel steering system, comprises oil circuit, is provided with rigidity oil pipe in this oil circuit, wherein, and the rigidity oil pipe that described rigidity oil pipe provides for the utility model.
The utility model also provides a kind of vehicle, comprises wheel steering system, wherein, and the wheel steering system that described wheel steering system provides for the utility model.
Pass through technique scheme, on the tube wall of this rigidity oil pipe, be provided with fold, this fold just can increase the heat diffusion area of oil pipe without increasing tubing length, therefore can overcome in prior art and cannot increase tubing length because vehicle space is limited, cause oil temperature too high, thereby cause the defect of each damage of components in steering system.
Other feature and advantage of the present utility model partly in detail are described the embodiment subsequently.
Accompanying drawing explanation
Accompanying drawing is to be used to provide further understanding of the present utility model, and forms a part for specification, is used from explanation the utility model, but does not form restriction of the present utility model with embodiment one below.In the accompanying drawings:
Fig. 1 is the structural representation of a kind of rigidity oil pipe of providing in the utility model embodiment.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.Should be understood that, embodiment described herein only, for description and interpretation the utility model, is not limited to the utility model.
As shown in Figure 1, the utility model provides a kind of rigidity oil pipe, and wherein, this rigidity oil pipe comprises tubular body 1, and the tube wall of this tubular body 1 has at least one fold 2, and the inside of this fold 2 is formed with the cavity with tubular body 1 internal communication.
Pass through technique scheme, on the tube wall of this rigidity oil pipe, be provided with fold 2, this fold 2 does not need to increase rigidity tubing length just can increase the heat diffusion area of rigidity oil pipe, therefore can overcome in prior art and cannot increase rigidity tubing length because vehicle space is limited, cause oil temperature too high, thereby cause the defect of each damage of components in steering system.
It should be noted that, the quantity of the fold 2 on this tube wall, depending on the space on vehicle and radiating requirements, is not done particular determination.
As a kind of preferred structural type, this fold 2 forms projection radially and/or the depression along tubular body 1.The shape of fold 2 can have diversity, for example, this fold 2 is only protruding along the radially formation of tubular body 1, or this fold 2 is only in depression along the radial shape of tubular body 1, again or this fold 2 along the radially formation projection of tubular body 1, between two adjacent protrusion, form depression etc.As long as the formation of the tube wall of tubular body 1 can increase the long-pending structure of tube wall surface and all belong to protection domain of the present utility model, repeat no more.
As a kind of embodiment of the present utility model, as shown in Figure 1, described fold 2 is a plurality of, and the plurality of described fold 2 forms ripple struction and has outwards outstanding crest and inside recessed trough.In order to obtain large heat diffusion area, on the tube wall of this tubular body 1, form a plurality of folds 2, by form crest and trough, increasing heat radiation area simultaneously.
For convenient processing, and it is unimpeded that fluid is flowed in rigidity oil pipe, and as a kind of concrete mode of execution, as shown in Figure 1, this fold 2 forms rounding off at crest and trough place.This rigidity oil pipe can be formed also and can be formed by punching press by casting, if excessively locating to produce dead angle, can make course of working operation inconvenience, and in use, when fluid is flowed through with the rigidity oil pipe at dead angle, the oil circulation at place, dead angle is not smooth, thereby causes heat radiation slowly.
For fear of oil pipe, in use produce fluid and reveal, as preferred embodiment a kind of, as shown in Figure 1, at least one end of tubular body 1 is provided with sealing configuration.For example, in this rigidity oil pipe and miscellaneous part connection procedure, can use rubber oil hose, rubber oil hose is sleeved on the sealing configuration of end of rigidity oil pipe, then use fixing device to fix at sealing configuration place.Sealing structural type is various, as formed annular protrusion on tube wall, or on tube wall, is provided with groove etc., as long as can realize sealing, prevents that fluid seepage all belongs to embodiment of the present utility model, repeats no more.
As a kind of concrete mode of execution, sealing structure forms annular protrusion 3.The section of this annular protrusion 3 can be set to various shape, and for example circular arc, or ellipse arc, as long as can mate with fixing device, completes sealing.
As a kind of concrete mode of execution, the outer surface of annular protrusion 3 is the form seamlessly transitting.In using process, annular protrusion 3 is wrapped in other oil pipes, rubber oil hose for example, and for easy for installation and guarantee the safety of the operator in installation process, the outer surface of annular protrusion 3 is set to seamlessly transit.
In order to simplify technique, reduce manufacture cost, and improve the tube wall strength of rigidity oil pipe, tubular body 1 is integrally formed with fold 2.Tubular body can adopt stamping process to form, and also can adopt casting technique formation etc., is integrally formed the working life that can guarantee tube wall.
The utility model also provides a kind of wheel steering system, comprises oil circuit, is provided with rigidity oil pipe in this oil circuit, wherein, and the rigidity oil pipe that rigidity oil pipe provides for the utility model.
The utility model also provides a kind of vehicle, comprises wheel steering system, wherein, and the wheel steering system that this wheel steering system provides for the utility model.
Below describe by reference to the accompanying drawings preferred implementation of the present utility model in detail; but; the utility model is not limited to the detail in above-mentioned mode of execution; within the scope of technical conceive of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
It should be noted that in addition, each concrete technical characteristics described in above-mentioned embodiment, in reconcilable situation, can combine by any suitable mode, for fear of unnecessary repetition, the utility model is to the explanation no longer separately of various possible compound modes.
In addition, between various mode of execution of the present utility model, also can carry out combination in any, as long as it is without prejudice to thought of the present utility model, it should be considered as content disclosed in the utility model equally.
