Description
Technical field
This utility model is related to automobile bushing technical field, more particularly to a kind of control arm bush assembly.
Background technology
It is now a large amount of in car suspension to adopt the flexible connection such as rubber bushing to meet the demands of Vehicle damper noise reduction, and hang
The precision fire of frame is also required to the matching of the various performance parameters of rubber bushing.China's rubber bushing application is very extensive, for rubber
The aspect research such as impact and optimization of the glue bushing to automotive performance, vibration insulation and noise reduction is a lot, and technical elements reach its maturity.
Rubber bushing have dynamic and static mechanical property, alternation it is external and in the presence of show dynamic behaviour,
Statics characteristic is shown in Slow loading.Rubber bushing in suspension system can hardly change low-frequency range isolation characteristicses
On the premise of, vibration isolating effect of the system in high band is substantially improved, is contributed to suspension system isolation high frequency intrinsic vibration, is reduced road
The in-car noise that face injustice causes.The vibration and impact transmitted can be alleviated from road surface by the characteristic for designing bushing, it is ensured that manipulate
Stability, has very important effect to lifting car load NVH performances.But bushing work under bad environment, in frequently fatigue endurance
Failure consequence caused by the lower liner wear for occurring of effect and slippage, can have a strong impact on vehicle safety.Commonly use in suspension

The modular ratio metal of bushing is little, therefore vibration insulation and noise reduction effect is obvious；The shape of rubber is unrestricted, and the rigidity of all directions can be
Certain limit is controlled, the Spring rate specific in three directions of selection that can be appropriate；Rubber easily firmly can be tied with metalwork
Close, make rubber bushing bear multidirectional load, that is, simplify structure, alleviate complete vehicle quality again；The inside of vulcanite
The friction of friction ratio metal inside is big, and with the tendency for increasing with frequency and increasing, therefore amplitude is less in resonance；Vulcanite
Have it is larger can reverse elastic deformation, and coefficient of elasticity is less than metal.Control arm bush assembly has following design problem：Stress
Concentrate, abrasion, fatigue rupture easily occur；To resist impact of the atmospheric environment to rubber, the filler used in elastomeric material
Grain diameter strictly will be controlled, and otherwise be easily caused rubber bushing performance not up to standard；The processing of metal pattern surface accuracy will be improved in production,
To avoid rubber surface and its nearby produce defect；Cure time to be controlled and curing temperature, in order to avoid affect the bushing fatigue longevity
Life；Rubber bushing as guaranteeing vehicle handling stability, the part significant to lifting car load NVH performances, it is necessary to meet
Some requires below：All directions rigidity requirement can be met, so that the behaviour for improving automobile is steady and NVH performances；Fatigue life meets
Require, avoid rubber bushing that fatigue rupture occurs as far as possible；Part easy processing, preferably meets assembling demand.
As shown in Figure 1-2, rigging position of the rubber bushing in multi-connecting-rod separated suspension, it is in proof procedure is made, existing
With the presence of the bushing problems with of technology：Easily cause stress concentration, fatigue rupture occurs, steady and NVH performances are grasped to car load and is made
Into having a strong impact on；Requirement need to be met to stiffness reliability respectively；Sulfuration process requires higher.
