Technical field
The invention belongs to technical field of automobile parts.Relating in particular to a kind of power assembly half active particle damping rubber suspends.
Background technique
In recent years, Automobile Design is to light and economical development, but the application of few cylinder, high power engine and lightweight vehicle frame (vehicle body) can cause the vibration that is passed to vehicle body by motor to aggravate, and vibration and noise characteristic in car are worsened.Engine behind front wheel-front wheel drive type the car that particularly adopts four poor cylinder four-stroke engines of balance, the vibration of power assembly is more and more outstanding on the impact of vehicle ride comfort.Meanwhile, people constantly improve again the requirement of riding comfort.In order to solve these contradiction, must improve dynamic assembly suspension device to the isolation effect that between power assembly and car body, vibration is transmitted, could effectively reduce body vibrations and internal car noise.
Existing dynamic assembly suspension device is divided into that General Purpose Rubber suspends, liquid resistance type rubber mounting, Semi-active mount and active engine mount.
Although that General Purpose Rubber suspends is simple in structure, cost is low, because rigidity is bigger than normal, the dynamically shortcoming such as sclerosis of underdamping and high frequency, be difficult to meet automobile power assembly vibration isolation requirement to suspension system in wider frequency range.
Liquid resistance type rubber mounting common are throttling pass, inertia channel type, inertia channel-fixing decoupling zero membranous type, inertia channel-activity decoupling zero membranous type various structures form, combine rubber damping and liquid-damped characteristic, performance suspends and improves a lot compared with General Purpose Rubber, but can only be in certain band limits vibration isolating effect obvious, and easily in the time of high frequency, produce dynamically sclerosis, cannot meet the vibration damping requirement of modern intermediate car.
Semi-active mount commonly semi-active type liquid resistance suspends, and this device can regulate the dynamic characteristic that suspend in real time according to the operating conditions of automobile, can realize wideband vibration isolation, vibration damping and noise reduction, has to be better than passive type liquid and to hinder the anti-vibration performance suspending.But suspend and increased control unit and actuator compared with the resistance of passive type liquid because semi-active type liquid resistance suspends, have that structure is more complicated, cost is high and the large problem that takes up room, be not widely adopted.
Active engine mount be by actuator directly produce dynamic force with negative function the vibration force on suspending, the dynamic force of transmitting between motor and car body is reduced greatly, thereby obtains best vibration isolating effect.The fast response time of active engine mount, its anti-vibration performance is better than Semi-active mount, but has system complex, power consumpiton is large, cost is high, reliability is lower and inconvenient shortcoming is installed, also seldom application on real vehicle at present.
