Description
Technical field
The utility model relates to a kind of automobile component, especially relates to a kind of lifting lug of automobile exhaust pipe.
Background technology
It is well known that exhaust system is one of important total one-tenth of automobile, purifying exhaust air discharge, absorption engine exhaust excitation noise are had a very important role by it. The quality of exhaust lifting lug design will directly have influence on the vibratory noise level of whole car, be the important factor affecting ride comfort. The overriding noise level of automobile exhaust system is the important factor affecting ride comfort. The overriding noise source of automobile exhaust system be in vehicle traveling process produce air noise, impulsive noise, the gentle flow noise of radiated noise, automobile travels on various road surface in addition, and the vibration excitation caused due to road surface roughness also can be delivered on vehicle body by hanger.
The outer shape of the Tailpipe lug of motor vehicle of prior art is forward and backward two sides is the plane being parallel to each other, side face is an approximate oval elastomerics up and down, elastomerics top is provided with the assembling hole being connected with body frame, and bottom is provided with the assembling through hole being connected with vapor pipe. Existing lifting lug of automobile exhaust pipe generally adopts elastomeric material to make, although its elasticity is better, certain damping effect can be played, but such hanger, intensity is not high, especially large-scale motor vehicle, and its vapor pipe is also bigger, the not high easy damage of the intensity of hanger, it is necessary to replacing lifting lug of vent pipe frequently. And the lifting lug of vent pipe of metal does not have elasticity, being also unfavorable for damping, vapor pipe also just easily damages.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of lifting lug of automobile exhaust pipe, and intensity height not easily damages, and damping compression-resistant performance is good and is suitable for assembling.
The utility model solves the problems of the technologies described above the technical scheme adopted: a kind of lifting lug of automobile exhaust pipe, comprise the rubber body of prism class structure, described rubber body is provided with the first notch, 2nd notch, 3rd notch and multiple open holes, the first described notch is positioned at the top of rubber body, first notch is the long and narrow type notch of arranged transversely, the upper side wall of the first notch is provided with the first lug boss to lower convexity, the 2nd described notch is positioned at the middle part of rubber body, the narrow two ends, middle part of the 2nd notch are roomy, the two ends of the 2nd notch are respectively provided with an extension portion upwards extended, the 3rd described notch is positioned at the bottom of rubber body, multiple open holes is distributed in upside and the downside of the 2nd notch, described rubber body is embedded with strut member, the first described notch, 2nd notch, in 3rd notch and multiple open holes are all wrapped in by strut member.
The periphery of described rubber body comprises the upper side, face, left side and the face, right side that connect successively, and described upper side, face, left side, face, right side are all round and smooth transition in connection face of circular arc face and two amounts. Circular arc face and round and smooth transition so that periphery of the present utility model is smooth, except seem attractive in appearance except, decrease the friction between the external world and the utility model periphery.
The middle part of the lower surface of the 2nd described notch is provided with the 2nd lug boss raised up. 2nd lug boss be arranged so that opening in the middle part of the 2nd notch reduces, integral, flexible is bigger, and the damping compression-resistant performance after installation is better.
The narrow two ends with the 3rd notch, the middle part of the 3rd described notch. The middle part of the 3rd notch is narrow, it is possible to bear pressure and drawing force that bigger upper and lower is upwards subject to.
Described the first notch, the 2nd notch, the 3rd notch are respectively about the rotational symmetry of vertical direction. Rotational symmetry meets the environment for use of lifting lug of vent pipe more.
Being provided with three open holess in described rubber body and be respectively the first open holes, the 2nd open holes and the 3rd open holes, the first described open holes and the 2nd mounting hole site are in the top of the 2nd notch and both are about the rotational symmetry of vertical direction. The setting of the first open holes, the 2nd open holes is for being connected with the parts on automobile, to reach the effect of damping compression-resistant.
The 3rd described mounting hole site is in the underface of the 2nd notch. 3rd mounting hole site is between the 2nd notch and the 3rd notch, automobile component are applied to the power of the 3rd open holes, can being cushioned preferably by the structure design of the 2nd notch and the 3rd notch, the Position Design of the 2nd open holes can reach good damping compression-resistant performance.
Compared with prior art, the utility model has the advantage of and the first notch, the 2nd notch, the 3rd notch and multiple open holes are set in rubber body. First notch, the 2nd notch, the setting of the 3rd notch and the setting of its structure are all the performances in order to strengthen its damping compression-resistant. First notch is the long and narrow type notch of arranged transversely, and the upper side wall of the first notch is provided with the first lug boss to lower convexity, and the narrow two ends, middle part of the 2nd notch are roomy, and the two ends of the 2nd notch are respectively provided with an extension portion upwards extended. And open holes is the upside and the downside that are positioned at the 2nd notch, when the utility model is squeezed power, now the first notch, the 2nd notch will be extruded and occur deformation thus to play shock absorption. When the utility model is subject to drawing force, it also it is same reason. The setting of strut member is the structural strength in order to improve the utility model entirety so that it is be not easy damaged. Inner support member is embedded in rubber body, it is possible to as far as possible few reduce to rubber body outside surface and each notch inner, open holes elasticity. Therefore inner support member can improve intensity while not affecting the elasticity of lifting lug of vent pipe, damping effect.
