Abstract
The invention relates to a support for an automobile exhaust pipe. The support for the automobile exhaust pipe comprises a support body. Two installation holes are formed in the support body. The axes of the two installation holes are parallel. Connecting sleeves are arranged in the installation holes. The support for the automobile exhaust pipe is characterized in that the outer diameter of each connecting sleeve is smaller than the diameter of the corresponding installation hole, each connecting sleeve and the corresponding installation hole are connected through a rubber layer arranged between the connecting sleeve and the corresponding installation hole, each rubber layer is provided with at least two buffering holes, and the buffering holes are evenly distributed in the circumferential direction. The support for the automobile exhaust pipe has the advantages that shake transmission between the exhaust pipe and an automobile frame can be reduced, the shake of the exhaust pipe is reduced and is not prone to ineffectiveness, and noise is low when the automobile runs.
Description
Technical field
The present invention relates to a kind of support for automobile exhaust pipe.
Background technique
At present, the exhaust pipe support of prior art comprises rack body and is fixed on two connecting sleeves on rack body, but due to otherwise connecting sleeve and rack body are integral type structure, connecting sleeve and rack body are welded to connect, therefore connecting sleeve and rack body are Hard link, then in connection after outlet pipe, the vibrations of outlet pipe and the vibrations of vehicle frame are easily transmitted mutually, it is larger that this just makes outlet pipe shake, easily there is the failure conditions ruptured in outlet pipe, and the noise of vibrations generation is in the process of moving larger.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of support for automobile exhaust pipe, solves the deficiencies in the prior art.
The technological scheme that the present invention solves the problems of the technologies described above is as follows: a kind of support for automobile exhaust pipe, it comprises rack body, described rack body is provided with two mounting holes, the axis of two described mounting holes is parallel to each other, connecting sleeve is equipped with in described mounting hole, it is characterized in that: the external diameter of described connecting sleeve is less than the aperture of mounting hole, described connecting sleeve be provided with rubber layer between mounting hole and be connected; Described rubber layer is provided with at least two cushion holes, and cushion hole is circumferentially uniform.
The invention has the beneficial effects as follows: after adopting above structure, compared with prior art, the present invention is less than the aperture of mounting hole due to the external diameter of connecting sleeve, and be provided with rubber layer between connecting sleeve with mounting hole and be connected, and rubber layer self has comparatively strong elastic deformation's ability, rubber layer is made to have good shock-absorbing effect, then the vibrations of outlet pipe and vehicle frame are under the filtration of rubber layer, vibrations are not easily transmitted each other at outlet pipe and vehicle frame, also vehicle frame would not be made to shake to be reacted on outlet pipe, outlet pipe is shaken less, and then make outlet pipe not easily occur the failure conditions ruptured, rubber layer is to after outlet pipe and vehicle frame shock-absorbing simultaneously, and then makes vehicle in motion, and the noise that vehicle frame and outlet pipe vibrations produce is also less.Therefore the present invention has the vibrations transmission that can reduce between outlet pipe and vehicle frame, outlet pipe is shaken and littlely not easily to lose efficacy, and noise also less feature when travelling.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is sectional view of the present invention.
Embodiment
Be described principle of the present invention and feature below in conjunction with accompanying drawing, example, only for explaining the present invention, is not intended to limit scope of the present invention.
As shown in Figure 1 and Figure 2, a kind of support for automobile exhaust pipe, it comprises rack body 1, described rack body 1 is provided with two mounting holes 2, the axis of two described mounting holes 2 is parallel to each other, be equipped with connecting sleeve 3 in described mounting hole 2, the external diameter of described connecting sleeve 3 is less than the aperture of mounting hole 2, described connecting sleeve 3 be provided with rubber layer 4 between mounting hole 2 and be connected.
Described rubber layer 4 axial length is greater than the axial length of mounting hole 2, and the axial two ends of rubber layer 4 are all in the outside of mounting hole 2, can to ensure in two mounting holes 2 that rubber layer 4 can integral type injection-compression molding like this, rack body part between two mounting holes 2 can be enveloped simultaneously, in two described mounting holes 2, rubber layer 4 is integral type structure, rubber layer 4 viewed from plan view, the shape of rubber layer 4 one in two mounting holes 2 is " ∞ " font.
The outer surface at the described axial two ends of rubber layer 4 is equipped with radial protrusion 5, described radial protrusion 5 free end end face is greater than the radius of mounting hole 2 to the perpendicular distance of mounting hole 2 axis, and the distance between certain rubber layer 4 axial two ends radial protrusion 5 equals the axial length of mounting hole 2.
Described rubber layer 4 is provided with at least two cushion holes 6, and (this example is four, also can be two, three, five or six etc.), and cushion hole 6 is circumferentially uniform, the shape of general cushion hole 6 and phasing not of uniform size are together, in this example four cushion holes 6, a pair shape is identical with size between two, and the cushion hole 6 of same shape and size is symmetrical.
Time shaping, first rack body 1 is placed in the die cavity of mould; Again two connecting sleeves 3 are respectively put in two mounting holes 2 of die cavity inner support body 1 subsequently, require the axis of connecting sleeve 3 and the dead in line of mounting hole 2 simultaneously; Then matched moulds, subsequently again by rubber pressure injection to the space between mounting hole 2 and connecting sleeve 3, finally cooling and the demoulding after.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
