Abstract
An hydraulic mounting comprises inner and outer rigid members radially spaced apart by an elastomeric member that forms a structural interconnection between the rigid members, a second elastomeric member axially spaced from the first elastomeric member and extending between the rigid members to define a fluid chamber, a rigid separator located within the chamber to divide it into high and low pressure zones, a fluid flow channel for passage of hydraulic fluid between the high and low pressure zones, a flexible member which interconnects between the separator and one of the inner and outer rigid members, and the separator being secured rigidly to the other of the inner and outer rigid members.
Claims25
An hydraulic mounting comprising an inner rigid member, an outer rigid member which lies radially outwards of the inner rigid member, a first elastomeric member which extends between the inner and outer rigid members at least in part to form a structural interconnection therebetween, a second elastomeric member which is spaced from the first elastomeric member, the second elastomeric member having a radially inner region and a radially outer region wherein said radially outer region lies radially outwards of said radially inner region, a fluid chamber defined at least in part by a space between the first and second elastomeric members, a rigid separator within said chamber to divide said chamber into high pressure and low pressure zones, said rigid separator having radially inner and radially outer regions and said radially inner and outer regions of the second elastomeric member being substantially rigidly secured respectively to said radially inner and outer regions of the rigid separator, and fluid flow means for passage of hydraulic fluid between said high and low pressure zones, said rigid separator being secured substantially rigidly relative to one of the inner and outer rigid members and being interconnected to the other of said rigid members by a flexible member, and said flexible member and one of said radially inner and outer regions of the second elastomeric member each being fluid tightly secured relative to one of the radially inner and outer regions of the rigid separator, wherein said rigid separator is secured substantially rigidly relative to said inner rigid member and also is interconnected to said outer rigid member by a flexible member.
