Description
Technical field
The present invention relates to a kind of hanging structure, more particularly to it is a kind of simple in structure, connection is reliable, the low bolt of manufacturing cost
Linking hanging structure.
Background technology
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 generally uses 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 manufacture
It is of 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。
Invention content
The present invention is mainly there is provided a kind of simple in structure, and connection is reliable, the low bolt connecting type hanging knot of manufacturing cost
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.
The above-mentioned technical problem of the present invention is mainly to be addressed by following technical proposals：A kind of bolt connecting type is hung
L-shaped upper hanger on hanging hang structure, including vehicle body and the exhaust pipe being lifted below L-shaped upper hanger, it is corresponding with the L-shaped upper hanger
Exhaust pipe be equipped with sunpender under L-shaped, sunpender is fixed on by screw rod on L-shaped upper hanger under L-shaped, and sunpender and L-shaped under L-shaped
Gum sleeve is set between upper hanger on corresponding screw rod, elastic top is connected on L-shaped upper hanger and L-shaped respectively at the both ends of gum sleeve
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-shaped, and is hung above and below in L-shaped
It is set with gum sleeve on screw rod between bar, elastic top is connected on the transverse direction of the corresponding upper and lower sunpender of L-shaped respectively for 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-shaped, 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-shaped sunpender be connected on exhaust pipe, vehicle fortune
Sunpender temperature rises with portion and expands extruding gum sleeve under L-shaped during row, and heat dissipation area increases, while making rubber sleeve pipe clamp
Tightly between the lateral face of the upper and lower sunpender of L-shaped, it is ensured that the two is reliably connected, simple in structure, and manufacturing cost is low.
Preferably, one end elastic top of the gum sleeve is connected on L-shaped upper hanger, the other end passes through heat resistant rubber pad
Piece apical grafting is under L-shaped on sunpender.By installing heat-resistant rubber gasket additional in gum sleeve corresponding with sunpender under L-shaped end, L is prevented
Gum sleeve denaturation caused by sunpender overheat under shape, it is ensured that hanging structure connection is reliable.
More preferably, it also is provided with heat resistant rubber pad 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-shaped upper hanger end, ensures 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-shaped 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 gum sleeve includes outer positioning sleeve and the same interior positioning sleeve being located 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, the elasticity of gum sleeve can be improved, under L-shaped 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
It is restored under the recovery force effect of radiation fins, to make upper and lower sunpender remain close-fitting state.
More preferably, wall thickness≤1mm of the interior positioning sleeve.Interior positioning sleeve keeps rational thickness, both ensures rubber
The elasticity of casing, and ensure it with certain support strength.
Therefore, a kind of bolt connecting type hanging structure of the invention tool has the advantage that：
1, the upper and lower sunpender heat dissipation area of L-shaped is big, and common NR may be used in gum sleeve, and manufacturing cost is low；
2, the upper and lower sunpender mode of L-shaped is higher, is conducive to NVH.
Description of the drawings：
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 implementation mode：
Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.
