Description

The high durable lifting lug of built-in aluminum frame
Technical field
Automobile exhaust technical field is the utility model is related to, especially a kind of high durable lifting lug of built-in aluminum frame.
Background technology
As the main structure part of automobile, air outlet duct system is collection exhaust gas, vibration, and the root of noise, for right Purify exhaust gas discharge, absorb engine exhaust excitation noise, and carry out the noise of this chassis system and have a very important role. Load-bearing and isolation component of the lifting lug rubber parts as exhaust system, rise suspension exhaust system and the excitation from exhaust system with The effect of vehicle body isolation.
Lifting lug rubber parts is located at bottom of car, and one end is ined succession vehicle body, and one end is ined succession exhaust system, its working environment is severe, Rubber lifting lug not only needs to bear the weight of support exhaust system, while also needs to bear to come from all directions under complex road condition Shock loading;And exhaust system is directly connected with engine exhaust, often also has and bear engine thermal and break the exhaust gas band of discharge The high temperature come.The lifting lug of vent pipe of pure rubber is easy to be broken at present, and the phenomenon that automobile exhaust pipe falls down often occurs, Especially kart, chassis is relatively low, and in rough road traveling, high convex is easy to scrape exhaust pipe, huge Big load very likely causes lifting lug of vent pipe cracked, or even is directly broken, therefore how to develop with rational Sound rigidity, excellent endurance quality while take into account and have good damping and silencing effect, dynamical lifting lug is to separated exhaust system The excitation of system, optimization vehicle NVH performances have the function that important.
Exhaust system is generally suspended on below underbody by multiple lifting lugs, when wheel is subject to larger vertical impact load When, relative displacement diminution between exhaust system and vehicle body, aluminium section bar effectively can prevent lifting lug to be overly compressed and influence tired at this time Labor characteristic;When being subject to vertical tensile load, by built-in aluminium section bar lifting lug can be prevented to be excessively stretched to influence fatigue Characteristic.And when lifting lug be subject to exhaust system apply thin tail sheep excitation when, can utilize lifting lug resilient support rubber realize every Shake, so as to effectively reduce influence of the exhaust system vibration to vehicle ride comfort;Therefore, the design and rubber of shackle structure The selection of material plays very big effect to exhaust system endurance quality and NVH performances.
In the prior art, there are following defect for the lifting lug for applying on general automobile exhaust system:First, General Purpose Rubber part by It is not perfect enough in material property, so as to reduce the NVH performances of rubber, influence vehicle comfort;2nd, the work of actual exhaust air system Condition is very harsh, existing design structure, not in view of the stress condition under this situation, so that exhaust lifting lug easily occurs to break Phenomenon is split, influences endurance quality.
Utility model content
The technical problems to be solved in the utility model is:In order to solve the problems, such as present in above-mentioned background technology, there is provided one The defects of planting the high durable lifting lug of improved built-in aluminum frame, solving lifting lug on current automobile exhaust system.
Technical solution is used by the utility model solves its technical problem:A kind of the high of built-in aluminum frame durable is hung Ear, including aluminium section bar stent and the rubber body positioned at aluminium section bar stent periphery, the aluminium section bar stent bottom are inlaid with one A M8 models bolt, offers two symmetrical overhead waist typed through hole, the aluminium section bar on the aluminium section bar stent It is located on stent in offering two symmetrically below overhead waist typed through hole and puts waist through hole, on the aluminium section bar stent Put in being located at and two symmetrical bottoms are offered below waist through hole put translot, the overhead kidney-shaped on the aluminium section bar stent is led to Be connected between hole by upper arc-shaped through-hole, on the aluminium section bar stent in put between waist through hole by arc lower through hole phase Connection.
Further, the overhead waist typed through hole, in put waist through hole and bottom is put translot and is located on the madial wall of both ends Offer longitudinal arc groove, be respectively connected with inside the longitudinal arc groove for lifting assembling firmness and stability Lateral arc extrusion elastic.
Further, to offer horizontal arc on upper arc-shaped through-hole inner bottom surface and arc lower the through hole inner top surface recessed Groove, the horizontal arc groove is internally connected with puts arc extrusion elastic for lifting assembling firmness and stability with.
Further, offered on the aluminium section bar stent between upper arc-shaped through-hole and arc lower through hole circular logical Hole.
Further, the aluminium section bar stent is bonded together by vulcanizing with rubber body.
Further, the aluminium section bar stent is fixedly connected by bottom bolts with automobile chassis.
The beneficial effects of the utility model are, the high durable lifting lug of built-in aluminum frame of the utility model a kind of passes through built-in Aluminum frame is inlayed with bolt, is then integrally vulcanized with silicon rubber, the product after vulcanization, has superpower durability and stability, Stent uses the aluminium section bar of expressing technique, not only significantly reduces the quality from body, reduces cost, and meets use The angle requirement of environment so that product dynamic stiffness obtains perfect embodiment so that vehicle NVH performances are lifted well, so that Meet passenger's overall comfort in the car.
