Description
Technical field
The present invention relates to automobile bushing technical field, more particularly to a kind of control arm bush assembly.
Background technology
It is a large amount of in present car suspension to meet the needs of Vehicle damper noise reduction using flexible connections such as rubber bushings, 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
Influence and optimization of the glue bushing to automotive performance, vibration insulation and noise reduction etc. research are 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, contributes to suspension system to isolate high frequency intrinsic vibration, reduces road
In-car noise caused by the injustice of face.Characteristic by designing bushing can alleviate the vibration and impact transmitted from road surface, it is ensured that manipulate
Stability, there is very important effect to lifting vehicle NVH performances.But bushing working environment is severe, in frequently fatigue endurance
Failure consequence caused by the lower liner wear and slippage occurred of effect, can have a strong impact on vehicle safety.Commonly used in suspension
Rubber bushing be made up of intermediate rubber body and metal sleeve, in order to improve durability, it is necessary to middle rubber bodies radially
Appropriate precommpression is carried out, rubber bushing when in use fix by outer barrel, and inner cylinder produces phase with the motion of wheel or other parts
The deformation answered, its deformation directly affect the performances such as kinematics, the dynamics of suspension.Rubber bushing has advantages below：Because of rubber
The modular ratio metal of bushing is small, therefore vibration insulation and noise reduction positive effect；The shape of rubber is unrestricted, and the rigidity of all directions can be
Certain limit controls, the Spring rate specific in three directions of selection that can be appropriate；Rubber easily can be tied firmly with metalwork
Close, rubber bushing is born multidirectional load, that is, simplify structure, alleviate complete vehicle quality again；Vulcanize the inside of rubber
The friction of friction ratio metal inside is big, and with the tendency for increasing with frequency and increasing, therefore amplitude is smaller in resonance；Vulcanize rubber
Have it is larger can reverse elastic deformation, and coefficient of elasticity is smaller than metal.Control arm bush assembly has following design problem：Stress
Concentrate, abrasion, fatigue rupture easily occurs；To resist influence of the atmospheric environment to rubber, the filler used in elastomeric material
Grain diameter will be controlled strictly, and it is not up to standard to be otherwise easily caused rubber bushing performance；The processing of metal pattern surface accuracy is improved in production,
To avoid rubber surface and its nearby produce defect；Cure time and curing temperature are controlled, in order to avoid influence the bushing fatigue longevity
Life；Rubber bushing is as vehicle handling stability is ensured, the part significant to lifting vehicle NVH performances, it is necessary to meet
Some is required below：All directions rigidity requirement can be met, the behaviour of automobile is steady and NVH performances to improve；Fatigue life meets
It is required that avoid rubber bushing that fatigue rupture occurs as far as possible；Part easy processing, preferably meet assembling demand.
As shown in Figure 1-2, rigging position of the rubber bushing in multi-connecting-rod separated suspension, it is existing in verification process is made
With the presence of the bushing problems with of technology：Easily cause stress concentration, fatigue rupture occurs, steady and NVH performances are grasped to vehicle and made
Into having a strong impact on；Respectively it need to meet to require to stiffness reliability；Sulfuration process requires higher.
