Abstract
A bush type mounting device having outer and intermediate sleeves, an inner metal portion and a rubber spring between the inner metal and the intermediate sleeve. The device has an inertial damping channel in an annular space between the outer sleeve and the intermediate sleeve. Damping decoupling is provided by a decoupling plate which extends radially outward from the intermediate sleeve in close association with a holding device.
Claims8
A bush type mounting device comprising:
- (a) an outer sleeve;
- (b) an intermediate sleeve, radially inward from said outer sleeve defining an annular space therebetween;
- (c) an inner metal portion radially inward from said intermediate sleeve;
- (d) a rubber spring bonded to an outer surface of said inner metal and to an inner surface of said intermediate sleeve diametrically located to provide said device with an upper chamber and a lower chamber, each containing a fluid;
- (e) an inertial damping channel molded in said annular space connecting said upper and lower chambers;
- and
- (f) means for hydraulically decoupling said fluid between said upper and lower chambers in said annular space, wherein said decoupler means comprises a plate extending radially outwardly between the intermediate sleeve and the outer sleeve in free association with a holding means;
- and
- (g) wherein said holding means is a saddle type structure having axially opposed slots whose widths are larger than the thickness of the plate.
