Description
Technical field
The present invention relates to automotive exhaust system structure part technical field, the low output ratio of Q-switching to free running of especially a kind of automobile exhaust system
Hanger rubber parts.
Background technology
Gas extraction system is one of important assembly on Hyundai Motor, to the discharge of purification waste gas, absorbs engine exhaust excitation
Noise has a very important role.Load-bearing and isolation component of the hanger rubber parts as gas extraction system, play suspension gas extraction system
With the effect that the excitation from gas extraction system is isolated with vehicle body.
Hanger rubber parts is located at bottom of car, and one end is ined succession chassis, and one end is ined succession gas extraction system, and its working environment is disliked
Bad, rubber hanger not only needs to bear the weight for supporting gas extraction system, while also needs to bear from each under complex road condition
Direction shock loading；And gas extraction system is directly connected with engine exhaust, often also has and bear high temperature.Therefore how to develop
The hanger of the low output ratio of Q-switching to free running, the dynamic stiffness of hanger is reduced, the excitation, optimization vehicle NVH performances to separated exhaust system have important
Effect.
Gas extraction system is typically connected on chassis by multiple hangers, and after vehicle launch, automobile engine starts work
Make, produce vibration, and discharge caused waste gas via blast pipe.In this exhaust process, shaken caused by engine work
Dynamic and waste gas caused vibration in discharge process from blast pipe, whole gas extraction system can be caused to produce certain vibration, this
When using the smaller rubber hanger of dynamic stiffness, the vibration that can more reduce gas extraction system is delivered on automobile chassis and vehicle body, this
The vibration of sample vehicle will reduce, and the NVH performances of vehicle can be more preferable, and the driving experience of vehicle can be more comfortable.
In the prior art, the hanger on general automobile exhaust system is applied following defect to be present：First, General Purpose Rubber hanger
Because material property is not perfect enough so that the dynamic stiffness of product is higher, so as to reduce the NVH performances of rubber, influences vehicle and relaxes
Adaptive；2nd, General Purpose Rubber hanger not enough optimizes due to structure design so that the dynamic stiffness of product is higher, the vibration isolating effect of hanger
It is not fine, influences the NVH comfortablenesses of vehicle.
The content of the invention
In order to solve problem present in above-mentioned background technology, the present invention provides a kind of improved automobile exhaust system with low
Output ratio of Q-switching to free running hanger rubber parts.
The technical solution adopted for the present invention to solve the technical problems is：A kind of low output ratio of Q-switching to free running hanger of automobile exhaust system
Rubber parts, including rubber body, described rubber body bosom position are to use serpentine structure, described rubber body
Both sides are connected using thin-walled.
Further, described rubber body two side top and bottom corner location are handled using fillet, described
The nearly rounded end of the left and right side wall of rubber body opens up the angled inclined-plane for being 17 °.
Further, described rubber body upper surface corresponds to the upper arc that serpentine locations of structures offers right low left high
Spigot surface, described rubber body lower surface corresponds to serpentine locations of structures and offers left low right high arc lower spigot surface, described
Rubber body madial wall be located on the right side of serpentine structure the fluting that two cross sections are triangle offered on inwall.
Further, described rubber body is internally located at before serpentine structure front and rear sides offers be connected respectively
Through hole and rearmounted through hole are put, described preposition through hole and rearmounted through hole inner width become larger from outside toward inner side.
Further, described upper arc guide surface is identical with arc lower spigot surface size.
Further, described preposition through hole is identical with rearmounted hole size.
Further, the distance between described preposition through hole and rearmounted through hole are 18mm.
The invention has the advantages that a kind of automobile exhaust system of the present invention will be conventional with low output ratio of Q-switching to free running hanger rubber parts
Holes rubber hanger uses Integral design, reduces the working sections product of product, can effectively reduce dynamic stiffness, lift vehicle
NVH performances, and the serpentine connection of middle part so that product has enough intensity, it is also ensured that the durability of product
It can meet to require, its is simple in construction, novel in design, and topology layout is reasonable, and production efficiency is big, cost is relatively low, has relatively low move
Quiet ratio, it can preferably lift vehicle NVH performances.
