Abstract
The utility model relates to auto parts and components technical field of structures, more particularly to a kind of bushing product structure, by the way that indented guiding chamfering is arranged in the bottom end of outer tube, to reduce bushing pressing-in force, increase product extrusion pressure simultaneously, product is prevented to be detached from pilot hole when damaging by pressure in press fitting with road test；And increase rubber buffer mechanism in plastic outer tube top and bottom end, so that product is when by axial force, slow down the contact between each part, it, on the one hand can lightweight bushing weight to reduce instant shock power between each part, and since outer tube is plastic material, another aspect product is without tightening, but still can achieve the purpose tightened, the stress between bushing rubber is reduced, bushing fatigue can be obviously improved.And adhesive is respectively provided between rubber body and inner and outer pipes, so that rubber breakage will not be caused because of product parts multiple-contact and fallen off, and then extend the service life of product.
Description
Technical field
The utility model relates to auto parts and components technical field of structures more particularly to a kind of bushing product structures.
Background technique
With the development of the automobile industry, automobile product is higher and higher to the lightweight requirements of bushing, general bush structure,
The shortcomings that mainly metal structure skeleton and rubber are bonded by adhesive, such product is that product weight is big, and press fitting difficulty is big,
This is that those skilled in the art do not expect to see.
Utility model content
In order to solve the above-mentioned technical problem, the technical solution of the utility model is there is provided a kind of bushing product structure,
In, it is described including metal inner pipe, plastic outer tube and the rubber body being set between the metal inner pipe and the plastic outer tube
It is vulcanization connection between rubber body and the metal inner pipe, the plastic outer tube；
The top and bottom end of the plastic outer tube are provided with rubber buffer structure；
The bottom end of the plastic outer tube is provided with the guiding chamfering for protruding from the plastic outer tube outer wall, and outside the plastics
Pipe offers notch in the two sides of the guiding chamfering.
Above-mentioned bushing product structure, wherein between the rubber body and the metal inner pipe, the plastic outer tube
It is provided with adhesive.
Above-mentioned bushing product structure, wherein the top of the plastic outer tube is equipped with boss.
Above-mentioned bushing product structure, wherein the bottom end of the plastic outer tube is provided with 2 guiding chamferings, and described in 2
Guiding chamfering is oppositely arranged.
Above-mentioned bushing product structure, wherein the plastic outer tube outer wall opens up fluted.
Above-mentioned utility model is with the following advantages or beneficial effects:
The utility model discloses a kind of bushing product structures, are fallen by the way that indented guiding is arranged in the bottom end of outer tube
Angle to reduce bushing pressing-in force, while increasing product extrusion pressure, and product is prevented to be detached from dress when damaging by pressure in press fitting with road test
Distribution；And increase rubber buffer mechanism in plastic outer tube top and bottom end, so that product when by axial force, slows down each zero
Contact between part, so that the instant shock power between each part is reduced, and since outer tube is plastic material, it on the one hand can lightweight lining
Weight is covered, another aspect product can achieve the purpose tightened without tightening, and reduce the stress between bushing rubber, can be with
It is obviously improved bushing fatigue.And adhesive is respectively provided between rubber body and inner and outer pipes, to will not repeatedly be connect because of product parts
Touching leads to rubber breakage and falls off, and then extends the service life of product.
Detailed description of the invention
Upon reading the detailed description of non-limiting embodiments with reference to the following drawings, the utility model and its spy
Sign, shape and advantage will become more apparent.Identical label indicates identical part in all the attached drawings.It can be by
Attached drawing is drawn according to ratio, it is preferred that emphasis is the purport of the utility model is shown.
Fig. 1 is the cross-sectional view for the bushing product structure just put in the utility model embodiment；
Fig. 2 is the schematic diagram for the bushing product structure put upside down in the utility model embodiment；
Fig. 3 is the enlarged diagram in Fig. 2 at A.
Fig. 4 is the structural schematic diagram for the plastic outer tube just put in the utility model embodiment；
Fig. 5 is the cross-sectional view of plastic outer tube in the utility model embodiment；
Specific embodiment
The utility model is further described with specific embodiment with reference to the accompanying drawing, but it is practical not as this
Novel restriction.
As shown in Fig. 1~5, the utility model discloses a kind of bushing product structures, specifically, the bushing product structure packet
Include metal inner pipe 1, plastic outer tube 2 and the rubber body 3 being set between metal inner pipe 1 and plastic outer tube 2, the rubber body 3
It is vulcanization connection between metal inner pipe 1, plastic outer tube 2；I.e. metal inner pipe 1 and plastic outer tube 2 are and the vulcanization of rubber is one
It rises；The top and bottom end of the plastic outer tube 2 are provided with rubber buffer structure 4, so that product slows down when by axle power
Damping effect when up and down motion is played in contact between each part, to reduce the instant shock power between each part；Specifically
, product is contacted with the rubber buffer structure 4 of 2 upper end of plastic outer tube, when by axial pressure assembling force to give plastics first
The contact of outer tube 2 buffers, and this process is equivalent to the process that tightens of bushing, and will not be excessive due to the amount of tightening, and causes product de-
Glue.In addition, the bottom end (i.e. the press fitting direction of plastic outer tube 2) of the plastic outer tube 2 is additionally provided with and protrudes from 2 outer wall of plastic outer tube
And 2 guiding chamferings 22 being oppositely arranged lead to the press fitting deformation of outer tube 2, and outside the plastics to prevent product from misplacing in press fitting
Pipe 2 offers notch 23 in the two sides of each guiding chamfering 22, so that respectively guiding chamfering 22 has the function of indented back-off,
It can achieve smaller pressure assembling force and bigger extrusion pressure.
In the embodiments of the present invention, it is provided between above-mentioned rubber body 3 and metal inner pipe 1, plastic outer tube 2
Adhesive, thus will not be because causing rubber body 3 damaged after product parts multiple-contact and falling off, service life is long.
In the embodiments of the present invention, the top of above-mentioned plastic outer tube 2 is equipped with boss 21, in favor of product pressure
Enter.
In the embodiments of the present invention, the moulding process of above-mentioned plastic outer tube 2 is injection molding, and 2 outer wall of plastic outer tube can
Polymorphic structure is taken further to mitigate weight on the basis of proof strength；For example, above-mentioned 2 outer wall of plastic outer tube offer it is recessed
Slot 24 is to mitigate the weight of plastic outer tube 2.
It should be appreciated by those skilled in the art that those skilled in the art are combining the prior art and above-described embodiment can be with
Realize change case, this will not be repeated here.Such change case has no effect on the substantive content of the utility model, not superfluous herein
