Abstract
An exhaust pipe support comprises a support body (1). Two installation holes (2) are arranged on the support body (1), axes of the two installation holes (2) are parallel to each other, connecting sleeves (3) are arranged inside the installation holes (2), the external diameters of the connecting sleeves (3) are smaller than diameters of the installation holes (2), and the installation holes (2) and the connecting sleeves (3) are connected through rubber layers (4). Compared with the prior art, the external diameters of the connecting sleeves are smaller than diameters of the installation holes, the installation holes and the connecting sleeves are connected through the rubber layers, the rubber layers have a good elastic deformation function and have a good shock-absorbing effect, the shock does not transmit between an exhaust pipe and a car frame easily under the condition that the shock of the exhaust pipe and the car frame is filtered by the rubber layers, the shock of the car frame cannot affect the exhaust pipe, the shock of the exhaust pipe is small, and the failure condition of the exhaust pipe, such as rupture, cannot occur easily. Simultaneously, after the rubber layers absorb the shock of the exhaust pipe and the car frame, and the noise due to the car frame and exhaust pipe shock is low during car driving.
Description
Technical field
The invention belongs to auto parts and components field, particularly relate to a kind of exhaust pipe support.
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 is hard connection with rack body, on connecting after outlet pipe, the vibrations of outlet pipe and the vibrations of vehicle frame are easily transmitted mutually, this just makes outlet pipe vibrations larger, easily there is the failure conditions of fracture in outlet pipe, and the noise of vibrations generation is in the process of moving larger.
Summary of the invention
The present invention is directed to above problem a kind of vibrations transmission reducing between outlet pipe and vehicle frame is provided, make the less difficult inefficacy of outlet pipe vibrations, and the also less exhaust pipe support of noise while travelling.
The present invention overcomes the above problems technological scheme used: a kind of exhaust pipe support with following structure is provided, 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, in described mounting hole, be equipped with connecting sleeve, the external diameter of described connecting sleeve is less than the aperture of mounting hole, is provided with rubber layer and is connected between described connecting sleeve and mounting hole.
Adopt after above structure, compared with prior art, the present invention is because the external diameter of connecting sleeve is less than the aperture of mounting hole, and between connecting sleeve and mounting hole, being provided with rubber layer is connected, and rubber layer self has compared with strong elasticity deformability, make rubber layer there is good shock-absorbing effect, the vibrations of outlet pipe and vehicle frame are under the filtration of rubber layer, vibrations are difficult for transmitting each other at outlet pipe and vehicle frame, just can not make vehicle frame vibrations be reacted on outlet pipe yet, make outlet pipe vibrations less, and then make outlet pipe not be prone to the failure conditions of fracture; Simultaneously rubber layer to outlet pipe and vehicle frame shock-absorbing after, and then make vehicle in motion, 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, makes the less difficult inefficacy of outlet pipe vibrations, and the also less feature of noise while travelling.
As improvement, described rubber layer axial length is greater than the axial length of mounting hole, and the axial two ends of rubber layer are all in the outside of mounting hole, in two described mounting holes, rubber layer is integral type structure, the rubber layer of this structure can envelope two part rack bodies between mounting hole, make the join strength of rubber layer and rack body and connecting sleeve higher, in using process, rubber layer is difficult for throwing off with rack body and connecting sleeve, makes stability in use of the present invention better.
As further improvement, on the outer surface at the described axial two ends of rubber layer, be equipped with radial protrusion, described radial protrusion free end end face is greater than the radius of mounting hole to the perpendicular distance of mounting hole axis, radial protrusion plays the effect to rubber layer axial limiting at the two ends of mounting hole, make rubber layer better with the stability that rack body is connected with connecting sleeve, rubber layer is more difficult in actual use throws off with rack body and connecting sleeve, and then stability in use of the present invention is further improved.
As further improving, described rubber layer is provided with at least two cushion holes, and cushion hole is along circumferentially uniform,, under the effect of cushion hole, make the elastic deformability of rubber layer better, and then make rubber layer better to the filtering effect of vibrations, can further reduce the vibrations transmission between outlet pipe and vehicle frame, make less more difficult inefficacy of outlet pipe vibrations, noise is less, and then makes using effect of the present invention better.

Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described further.
A kind of exhaust pipe support as depicted in figs. 1 and 2, 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, in described mounting hole 2, be equipped with connecting sleeve 3, the external diameter of described connecting sleeve 3 is less than the aperture of mounting hole 2, is provided with rubber layer 4 and is connected between described connecting sleeve 3 and mounting hole 2.
Described rubber layer 4 axial lengths are 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 guarantee like this in two mounting holes 2 that rubber layer 4 can integral type injection-compression molding, rack body between two mounting holes 2 partly can be enveloped simultaneously, in two described mounting holes 2, rubber layer 4 is integral type structure, that from plan view, sees rubber layer 4 one in 4, two mounting holes 2 of rubber layer is shaped as " ∞ " font.
On the outer surface at described rubber layer 4 axial two ends, be equipped with radial protrusion 5, described radial protrusion 5 free end end faces are greater than the radius of mounting hole 2 to the perpendicular distance of mounting hole 2 axis, the distance between rubber layer 4 axial two ends radial protrusions 5 equals the axial length of mounting hole 2 certainly.
It is four that described rubber layer 4 is provided with at least two these examples of cushion hole 6(, also can be two, three, five or six etc.), and cushion hole 6 is along circumferentially uniform, the shape of general cushion hole 6 and phasing not of uniform size are same, in four cushion holes 6 of this example, a pair of shape is identical with size between two, and identical shaped and big or small cushion hole 6 is symmetrical.
During moulding, 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 dead in line of axis and the mounting hole 2 of connecting sleeve 3 simultaneously; Then matched moulds, subsequently again by rubber pressure injection to the space between mounting hole 2 and connecting sleeve 3, finally after the cooling and demoulding.
Above embodiment is only preferred embodiment of the present invention, and the present invention is not limited only to above embodiment and has also allowed other structural change, allly in rights to independence claimed range of the present invention, changes, and all belongs to protection domain of the present invention.
