Bolt through hydraulic mount with and without a decoupler

A hydraulic mount for coupling a first component and a second component in a vehicle, the mount comprising:

• a first elastomeric member defining a first portion of a first chamber;
• a second elastomeric member defining a second portion of the first chamber and a second chamber, the first chamber and the second chamber each able to retain fluid in a liquid seal manner;
• an inner tube assembly defining an opening for receiving a bolt, wherein the first elastomeric member and the second elastomeric member are fixedly secured to an outer surface of the inner tube assembly;
• an inner ring fixedly coupled to the inner tube assembly at a position between the first chamber and the second chamber, wherein the second elastomeric member is fixedly secured to an outer surface of the inner ring;
• and
• a decoupler fixedly disposed within the inner ring, the decoupler adapted to move between rigid surfaces adjacent the first and second chambers, wherein the decoupler includes:
• a decoupler housing including an annular channel, a bottom surface, and a lower opening in the bottom surface, the lower opening enabling fluid to flow into and out from the annular chamber relative to the second chamber;
• a decoupler ring movable axially within the annular channel;
• a decoupler cap configured to rest at least partially within the decoupler housing and including at least one opening for enabling fluid flow therethrough into and out from the annular chamber relative to the second chamber;
• and
• wherein a surface of the decoupler housing and a surface of the decoupler cap define axially spaced apart surfaces that act as limits of axial travel for the decoupler ring.
