Hydraulic damping bearing for vehicle engine compartments forms damping channel walling from displacement element sectors elasticaly deforming in case of anchorage parts movement.

摘要

Some sectors at least of the damping channel (14,17,18) wall are formed by a displacement element (16) in the form of an endstop limiting flow between first and second anchorage parts (2,3). Some of the channel wall sectors are made up by a support (13) fitted to the second part (3) so the displacer (16) bears on the support (13) with a sector (22) forming a first sector of the channel wall where the bearing (1) is partly sprung into place. Thus when part (2) of the anchorage moves relative part (3), the displacer (16) is necessarily inelasticaly deformed. Channel wall sector (22) will be seen to lead up to the support (13) in the axial sense of the bearing. A second displacer (16) sector (23) forms a second part of the channel wall (14,17,18) and adjoins the second anchorage part (3).
