Abstract
The utility model provides a reducing bolt for commercial car, this reducing bolt can be used to being connected of commercial car frame and attached supports such as some fixed pipelines, pencil. Through the reducing bolt that uses this structure, the nut of cooperation small dimension replaces bolt, the nut of original big specification, can realize the cooperation and the connection of major diameter hole frame and minor diameter hole support well, reaches the lightweight and falls heavy purpose, can also material saving. Including hexagon head, a diameter section, reducer, the 2nd diameter section and threaded rod, the cooperation in hole on a diameter section and the frame, a diameter section and the 2nd diameter section are connected to the reducer, and the reducer is toper or curved body structure, the 2nd diameter section and the same thread processing and the final phase of a project of being used for of threaded rod part diameter, the 2nd diameter section fastens with the hole cooperation on the attached supports such as fixed pipeline, pencil. This reducing bolt can cooperate in the different connecting piece use of two pore sizes.
Description
Technical field
The utility model relates to a kind of commercial vehicle reducing bolt, belongs to field, commercial car chassis.
Background technique
The vehicle frame of commercial vehicle is as important bearing structure, and the component of automobile all make to be fixed by bolts on vehicle frame.Consider that versatility that component install, the cost of processing and convenience control, vehicle frame adopts the hole of same size diameter.Because installing the needs of other important bearing members, on vehicle frame, the size of bore dia is for accessory holder such as fixing pipeline, wire harness, uses and too wastes compared with the bolt of large gauge.And often such bolt uses much on automobile, then coordinate the nut of large gauge, the waste of material must be caused, be more unfavorable for the light-weight design of commercial vehicle.If there is a kind of commercial vehicle reducing bolt, both can be matched with the diameter of vehicle frame universal hole, reduce material by reducing again, coordinate the nut of small dimension to use, fix the accessory holder such as pipeline, wire harness.So no matter at saving material, or the light-weight design of commercial vehicle has very large benefit.Further, very large benefit is also had to the product competition advantage of main engine factory.
Model utility content
For deficiency of the prior art, the utility model aims to provide a kind of commercial car reducing bolt, for the connection of the accessory holder such as vehicle frame and fixing pipeline, wire harness.
The versatility of before installing in order to component due to commercial car vehicle frame, the cost of processing and the control of convenience, vehicle frame adopts the hole of same size diameter.Because installing the needs of other important bearing members, on vehicle frame, the size of bore dia is for accessory holder such as fixing pipeline, wire harness, uses and too wastes compared with the bolt of large gauge.Vehicle uses a lot of individual such bolt in addition, adds the nut coordinating large gauge, not only can cause the waste of material, and unfavorable to the light-weight design of commercial vehicle.Reduce material by reducing, coordinate the nut of small dimension to use.Both can be matched with the diameter of vehicle frame universal hole, the object of saving material and automotive light weight technology design can have been reached again.
In order to solve the problem, the technical solution of the utility model is:
A kind of commercial car reducing bolt comprises hexagon head, the first diameter section, reducer, Second bobbin diameter section and threaded stem,
In axial direction, hexagon head, the first diameter section, reducer, Second bobbin diameter section and threaded stem connect successively;
The diameter of the first diameter section is greater than the diameter with Second bobbin diameter section; First diameter section coordinates with hole on vehicle frame;
Reducer connects the first diameter section and Second bobbin diameter section, and reducer is taper or arc body structure;
Second bobbin diameter section is identical with threaded shank portion diameter for screw thread process and ending, and Second bobbin diameter section coordinates fastening with the hole in the accessory holder such as fixing pipeline, wire harness.
Further, the first diameter section, Second bobbin diameter section are connected with the link bolt of different pore size size respectively.
Accompanying drawing explanation
Fig. 1 is the plan view of an embodiment of the utility model commercial car reducing bolt;
Fig. 2 is the left view of an embodiment of the utility model commercial car reducing bolt;
Fig. 3 is the plan view of an embodiment of the utility model commercial car reducing bolt;
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
Composition graphs 1 to Fig. 2, this reducing bolt comprises: hexagon head 1, first diameter section 2, reducer 3, Second bobbin diameter section 4 and threaded stem 5.This bolt has the fitting surface that two diameter are different.The bolt that this bolt is used for the different link of pore size connects.
In a preferred embodiment, reducer is taper.
In a preferred embodiment, reducer is circular arc transition body.
Hexagon head is used for the fastening of bolt, first diameter section for the coordinating of large diameter hole on vehicle frame, reducer is used for the transition of different diameter parts, and Second bobbin diameter section is used for screw thread process and ending, threaded stem be used for support small diameter bore coordinate and nut screw fastening.The bolt realizing different large small apertures link connects.
Finally should be noted that: above embodiment is only in order to illustrate that the technological scheme of this case is not intended to limit; Although be described in detail this case with reference to preferred embodiment, those of ordinary skill in the field have been to be understood that: still can modify to the embodiment of this case or carry out equivalent replacement to portion of techniques feature; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technological scheme scope of this case request protection.
