Description
Technical field
This utility model relates to a kind of automobile component, in particular to a kind of automobile exhaust system overhead support and outstanding
Hang device.
Background technology
Automobile exhaust system is an important component part of automobile, and its Main Function is that discharge electromotor work is discharged
Waste gas, make the exhaust emission of discharge reduce simultaneously, noise reduce.Automobile exhaust system when mounted, its one end and electromotor
Being connected, other end is connected with vehicle body by suspension arrangement, is connected with fore sub frame especially by a suspension arrangement, front secondary car
The overhead support of frame side is U-shaped support, thickness 2.8mm, due to installation site requirement, the secondary car of mounting plane distance of overhead support
Frame floor side member 48.8mm.The vibration of driving source passes to gas extraction system, passes to vehicle body by suspension arrangement the most again, vehicle body
Vibration is directly passed to passenger by seat, steering wheel and floor.The vibration of vehicle body simultaneously also can radiate, and produces in car
Noise.
Suspension arrangement is mainly made up of two overhead support and a vibration isolator (rubber hanging block), is connected with gas extraction system
Connecing while being tension side, its overhead support is referred to as active bracket；Be connected while crying passive limit with vehicle body, its overhead support is referred to as
Passive support；Generally use transport to evaluate the working effect of a vibration isolator, transport refer to tension side magnitude of vibrations with
The ratio of passive limit magnitude of vibrations.Vibration isolating effect depends on the rigidity of vibration isolator.Overhead support-vibration isolator-overhead support composition
Suspension arrangement, is the passage of vibration transmission, and overhead support has certain rigidity, just looks like to be a hard spring, vibrating isolation system
Rigidity be not only the rigidity of vibration isolator, but also depend on the rigidity of overhead support, the global stiffness that this three is together in series is
It is the rigidity of vibrating isolation system.
The vibration of gas extraction system is delivered on vehicle body by overhead support.When the power being delivered on vehicle body is excessive, passenger
Just can be clearly felt that the structural radiation noise vibrating or being produced by vibration from gas extraction system.For ensureing that good NVH (makes an uproar
Sound-Noise, vibration-Vibration and sound vibration roughness-Harshness) performance, need that overhead support is carried out rigidity and set
Meter.For ensureing that overhead support has good vibration isolating effect, the rigidity of overhead support must arrive greatly necessarily than the rigidity of vibration isolator
Degree, usually requires that active and passive side overhead support rigidity more than at least 5 times is in the rigidity of vibration isolation rubber.
Due to mark this position of vehicle overhead support be to be directly installed on the floor side member of subframe, so to this two
When the dynamic stiffness of individual mount point is analyzed, find that the Y-direction dynamic stiffness level of U-shaped support (overhead support) mount point is significantly lower than
Mark post car, it is excessive that this is easily caused the vibration of gas extraction system Y-direction, causes internal car noise, causes that passenger's is uncomfortable.
