Description
Technical field
The present invention relates to a kind of hanging structure more particularly to a kind of structure are simple, connection is reliable, the low bolt of manufacturing cost
Linking hanging structure.
Background technique
In vehicle structure, the connection of the high-temperature heating parts and car body such as muffler is realized often by hanging structure,
In order to adapt to high temperature environment, in traditional automobile hanging structure, overhead support generallys use hook-shaped rod structure, due to
Overhead support thermal conductivity is strong, and the hanging rubber in structure can only take the preferable EPDM rubber of heat resistance or silica gel, not only manufactures
It is at high cost, and structure causes it to be also easy to produce loosening or overload in cold-hot condition, connection reliability is poor, is also easy to produce resonance, is unfavorable for
NVH。
Summary of the invention
For the present invention mainly there is provided a kind of structure is simple, connection is reliable, and the low bolt connecting type of manufacturing cost hangs knot
Structure solves manufacturing cost height existing in the prior art, and connection reliability is poor, is also easy to produce resonance, is unfavorable for the technology of NVH etc.
Problem.
Above-mentioned technical problem of the invention is mainly to be addressed by following technical proposals: a kind of bolt connecting type is hung
Hanging hang structure, it is corresponding with the L shape upper hanger including the L shape upper hanger on vehicle body and the exhaust pipe being lifted below L shape upper hanger
Exhaust pipe be equipped with sunpender under L shape, sunpender is fixed on L shape upper hanger by screw rod under L shape, and sunpender and L shape under L shape
Gum sleeve is set between upper hanger on corresponding screw rod, the elastic apical grafting of both ends difference of gum sleeve is in L shape upper hanger and L shape
On the lateral face of lower sunpender.Implement connection by running through screw rod between the lateral face of the upper and lower sunpender of L shape, and is hung above and below in L shape
Gum sleeve is set on screw rod between bar, elastic apical grafting is distinguished in the transverse direction of the corresponding upper and lower sunpender of L shape in the both ends of gum sleeve
On face, due to implementing to be rigidly connected by screw rod between the upper and lower sunpender of L shape, the gum sleeve being sleeved on outside screw rod can
The lower General Purpose Rubber of use cost to reduce vibration, in structure due under L shape sunpender be connected on exhaust pipe, vehicle fortune
Sunpender temperature rises with portion and expands extruding gum sleeve under L shape during row, and heat dissipation area increases, while making rubber sleeve pipe clamp
Tightly between the lateral face in the upper and lower sunpender of L shape, it is ensured that the two is reliably connected, and structure is simple, and manufacturing cost is low.
Preferably, one end elasticity apical grafting of the gum sleeve, on L shape upper hanger, the other end passes through heat resistant rubber pad
Piece apical grafting is under L shape on sunpender.By installing heat-resistant rubber gasket additional in gum sleeve end corresponding with sunpender under L shape, L is prevented
The denaturation of gum sleeve caused by sunpender overheats under shape, it is ensured that hanging structure connection is reliable.
More preferably, heat resistant rubber pad also is provided in the gum sleeve other end opposite with the heat-resistant rubber gasket
Piece.Heat-resistant rubber gasket is equally set in gum sleeve corresponding with L shape upper hanger end, guarantees the performance of gum sleeve.
Preferably, the outer ring surface of the gum sleeve extends inwardly to form arc groove.Thin both ends among gum sleeve
Greatly, it can ensure that the L shape upper and lower sunpender transverse direction face of gum sleeve both ends and respective side comes into full contact with while saving raw material,
So as to effectively reduce vibration.
Preferably, the interior positioning sleeve that the gum sleeve includes outer positioning sleeve and is located in together in outer positioning sleeve mesoporous,
It is folded with radiation fins in outer positioning sleeve and outer positioning inner room, the corresponding integral type of radiation fins is connected to outer positioning sleeve and interior positioning sleeve
On.By the way that radiation fins is arranged in gum sleeve, first is that the elasticity of gum sleeve can be improved, under L shape when sunpender expanded by heating,
It is clamped in after gum sleeve compressive deformation between upper and lower sunpender, to avoid Joint failure caused by screw bolt loosening, exists again after cooling
The restoring force effect of radiation fins is lower to restore, so that upper and lower sunpender be made to remain close-fitting state.
More preferably, wall thickness≤1mm of the interior positioning sleeve.Interior positioning sleeve keeps reasonable thickness, both guarantees rubber
The elasticity of casing, and guarantee it with certain support strength.
Therefore, a kind of bolt connecting type hanging structure of the invention has an advantage that
1, the upper and lower sunpender heat dissipation area of L shape is big, and gum sleeve can use common NR, and manufacturing cost is low；
2, the upper and lower sunpender mode of L shape is higher, is conducive to NVH.
Detailed description of the invention:
Fig. 1 is a kind of structural schematic diagram of bolt connecting type hanging structure of the present invention；
Fig. 2 is the structural schematic diagram of gum sleeve in the present invention.
Specific embodiment:
Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.
