Further, the base and said inner tube are in inverted " t " font structure, and the base and said inner tube one into
Type.
Further, said inner tube is equipped with for the endoporus of car bottom plate corresponding aperture position assembling and for assembling screw end head
Screens groove, and the endoporus is connected with the screens groove.
Further, the screens groove diameter is more than the diameter of bore, and the screens groove and endoporus center phase
Together.
Further, rubber spring installation nested with said inner tube, and the rubber spring is equipped with annular groove, it is described
Mass block fuses into the annular groove.
Further, some grooves are uniformly distributed along the edge of said inner tube.
Further, the rubber spring lower part is equipped with circumferential U-shaped groove.
Using the above structure, which is installed at the suspension rack of engine, the rubber spring is located at
Said inner tube periphery, and is supported by the base, can axial absorbing and radial direction absorbing at the same time, open up on the rubber spring
Groove is conveniently adjusted solid frequency ratio example axially and radially, and dynamic vibration absorber is met the requirement of damping ratio, improves damping effect.
To sum up, the beneficial effects of the utility model are：Using structure of the rubber spring in mounting base, Ke Yishi
Now axially and radially two-way vibration damping, and some grooves are offered on the rubber spring, can adjust as needed it is axial and
The solid frequency ratio example of radial direction, and meet the requirement of damping ratio, the vibration that engine system is transferred on vehicle body is reduced, improves vehicle
Damping property and effect.
