Skilled addressee readily understands that, in the case of using said structure, engine is suspended in vehicle frame
On, engine vibration vertically or shake are converted into level of the sliding block in slide rail and slide, and this level is slided
The dynamic elastic component for being arranged on slide rail both sides is significantly decayed, so as to effectively inhibit engine luggine in vehicle frame and main cabin
Transmission, improves the NVH characteristics and riding experience of motor vehicle.It should be pointed out that the present invention does not use such as shock-reducing rubber
The vibration isolating device of pad etc, but the vertical motion of engine is dexterously converted into by level using sliding block and slide rail and is slided
It is dynamic.The effectiveness in vibration suppression that the mode of this " dredging " is obtained is substantially better than " intercepting " isolation method of prior art.According to invention
The experimental data of people, for same engine, under the rotating speed of 800rpm, 1500rpm and 3000rpm, with vibration damping rubber cushion
The noise in main cabin and vibration are reduced 25%, 50% and 37% respectively compared to vibration absorber of the invention.Additionally, this area
Technical staff it is easily understood that using bulb connect in the case of, activity of the connecting rod relative to engine and sliding block
The free degree is larger, and this aspect enables the vertical motion of engine to be swiftly delivered on sliding block and is converted into the level of sliding block
Slide, on the other hand can adapt to again because of error caused by assembling or manufacture.Furthermore, skilled addressee readily understands that
