Abstract
The utility model discloses an elastic cushion block for an automobile exhaust tail pipe. The elastic cushion block comprises an elastic cushion block body, the elastic cushion block body is provided with a first connecting hole in the upper portion and a second connecting hole in the lower portion, the elastic cushion block body is a rhombic elastic body, a first rhombic hole and a second rhombic hole which are symmetric left and right are formed in the middle of the elastic cushion block body, a rectangular hole is formed between the first rhombic hole and the second rhombic hole, and the first rhombic hole and the second rhombic hole are communicated through the rectangular hole. The elastic cushion block for the automobile exhaust tail pipe has the advantages that the stress direction and the elastic structure of two arms are located on the same straight line, only tensile deformation is generated, so that the possibility of the bending failure is reduced to a great degree, strength and stability of the structure are improved, the service life is prolonged, deformation is larger, vibration frequency of an exhaust system is effectively buffered, and noise is reduced; the rhombic longitudinal structure is the smallest, and it can be effectively avoided that due to vibration in the traveling process, motion interference happens between the elastic cushion block and peripheral parts.
Description
Technical field
The utility model belongs to automobile technical field, particularly a kind of exhaust tail pipe of automobile elastic cushion block.
Background technology
Driving engine is the topmost vibration of car load and driving source, and its vibration passes to exhaust system, then passes to vehicle body by elastic cushion block.Along with the design of body lightening, the car internal vibration and the noise problem that are caused by exhaust system excitation are comparatively common in vehicle newly developed, and affect the traveling comfort that automobile is taken.Freeing pipe and under-carriage are coupled together the effect of load-bearing and vibration isolation played by rubber cushion blocks, the excitation and the vehicle body that come from exhaust system can be kept apart, meanwhile, rubber cushion blocks can also be controlled the displacement range of freeing pipe, plays the effect that reduces exhaust system vibration and reduce noise.
But rubber cushion blocks stiffness characteristics of the prior art is larger, itself and periphery part move while interference, can produce larger noise, and long-term use is easy to circumferential component to break, and vibration isolating effect is poor, therefore need volume and cushion effect degree to rubber cushion blocks to carry out certain improvement.
Utility model content
Technical problem to be solved in the utility model is, a kind of exhaust tail pipe of automobile elastic cushion block is provided, it is simple in structure, volume is little, elasticity by force, not fragile, there is the effect of good vibrationproof noise control.
For solving the problems of the technologies described above, the exhaust tail pipe of automobile elastic cushion block that the utility model provides, it comprises elastic cushion block main body, described elastic cushion block main body top is provided with the first connecting bore being connected with under-carriage, bottom is provided with the second connecting bore being connected with freeing pipe, described elastic cushion block main body is a rhombus elastic body, the middle part of described elastic cushion block main body is provided with symmetrical the first diamond hole and the second diamond hole, between described the first diamond hole and the second diamond hole, be provided with oblong aperture, the first diamond hole and the second diamond hole are connected by oblong aperture.Elastic cushion block main body is made as to rhombus, the elastic construction that is subject to force direction and two arms of its two arm is in a straight line, only produces tensile deformation, thereby reduced to a great extent the possibility that bends and lost efficacy, the intensity and the stability that have improved structure, increase the service life.Be provided with at elastic cushion block middle part the first diamond hole, oblong aperture and the second diamond hole that communicate, make elastic cushion block in the time there is tensile deformation, there is larger deflection, effectively alleviated the oscillation frequency of exhaust system, also reduced noise simultaneously.
As preferably, the elastomeric upper and lower corner of described rhombus is by the first arc transition, and left and right corner is by the second arc transition.Make rhombus elastic body stressed even everywhere, increase the service life, in rhombus elastic body corner, stress easily occurs and concentrate, effectively reduce the collision dynamics of rhombus elastic body corner and periphery part, fall the noise reduction that shakes.
As preferably, the length at the elastomeric upper and lower two ends of described rhombus: the length=1.125:1 at two ends, left and right.Longitudinal construction minimum, can effectively avoid it to vibrate in motion with periphery part and move interference, improves stability.
As preferably, described oblong aperture and the first diamond hole and the second diamond hole joining place are by three-arc transition, the corner up and down of the first diamond hole and the second diamond hole is by the 4th arc transition, and the horizontal corners of the first diamond hole and the second diamond hole is respectively by the 5th arc transition; Described the 5th circular arc is concentric with the second circular arc.Ensure that elastic cushion block is stressed even everywhere, convenient processing simultaneously.
As preferably, described in to be positioned at the first circular arc of rhombus elastic body top concentric with the first connecting bore, be positioned at the first circular arc below rhombus elastic body concentric with the second connecting bore.Easy to process, stressed even.
As preferably, in the middle part of the outside face of described elastic cushion block main body, be provided with annular boss.Further improve the buffering effect of elastic cushion block main body.
Adopt after above structure, exhaust tail pipe of automobile elastic cushion block of the present utility model compared with prior art, have the following advantages: the elastic construction that is subject to force direction and two arms of two arms is in a straight line, only produce tensile deformation, thereby reduce to a great extent the possibility that bends and lost efficacy, the intensity and the stability that have improved structure, increase the service life; Be provided with at elastic cushion block middle part the first diamond hole, oblong aperture and the second diamond hole that communicate, make elastic cushion block in the time there is tensile deformation, there is larger deflection, effectively alleviated the oscillation frequency of exhaust system, also reduced noise simultaneously; Rhombus longitudinal construction minimum, can effectively avoid it to vibrate in motion with periphery part and move interference, improves stability.
