The automatically controlled variable restrictor cellular type Semi-active mount of condition vibration.
Background technique
With the rapid development of automotive engineering, low cost, lightweight, energy conservation and environmental protection have been one kind of Hyundai Motor development
Trend, requirement of the consumer to automobile various aspects of performance is also higher and higher, especially especially prominent to the requirement of vehicle ride comfort
Out, the NVH of comfort and automobile（Noise vibration & harshness）Performance is closely bound up, and automobile suspended system
The superiority and inferiority of design is most important to vehicle NVH performance.The engine exciting source important as vehicle is to influence vehicle seating to relax
The transmitting of one of most important system of adaptive, vibration is to be transmitted to vehicle body or vehicle frame by suspension system connected to it
On, therefore, it is effectively isolated or reduces to the maximum extent the vibration that power assembly is transmitted on vehicle body or vehicle frame, it is whole to optimizing
Vehicle NVH performance is particularly critical.Suspension system is the critical elements for being effectively isolated or reducing power assembly transmitting vibration, vibration isolation
The superiority and inferiority of performance directly affects the quality of vehicle NVH performance, to influence vehicle ride comfort while also will affect zero

It arrives, seriously affects the riding comfort of driver and passenger.Therefore, idling operation is the important operating condition of automobile, idle vibration and noise
It is the NVH phenomenon that very heavy vehicle is wanted.
In order to be effectively isolated or reduce the vibration that automobile power assembly is transmitted on vehicle body or vehicle frame, in automobile power
Device suspension system between assembly and vehicle body.For power assembly angle, engine either idling operation or other
Driving cycle, its own can generate reciprocal unbalance inertia force and torque fluctuations at work, this since engine itself is tied
The main vibration source of unbalance inertia force caused by structure and torque fluctuations, exactly suspension system, power assembly and suspension system
A vibration isolator is constituted, the vibration that power assembly is transmitted to vehicle body is effectively isolated.If the vibration of power assembly cannot have
The isolation of effect ground, will be delivered to each position of automobile, cause the vibration of other components, can also generate noise, influence driver
