Car engine hydraulically damping rubber mount - has damping duct with two radial sidewalls independently rotatably mounted

摘要

The hydraulically damping car engine rubber mount has two rigid, axially facing ends (17a, b) and at least two damping fluid filled chambers (9, 10) axially behind each other. The chambers are joined by an annular damping duct (12) in a partition (13) across the mount axis (14). The damping duct has two radial sides (15a, b) and two axial ends. One side is connected to a drive (16), while the other one can be stopped, or turns with the first side. At least one end is joined to one side by a thread (18) parallel to the mount axis. ADVANTAGE - Both the damping duct length and cross section can be independently adjusted from outside.
