Hydraulically damping bushing for bearing e.g. components in commercial vehicle, has first and second rubber bars provided between bearing core and bearing cage and integrated into duct, and third rubber bar not integrated into duct

摘要

The bushing has a sleeve-like bearing cage (2) formed in a bearing housing (1), and a supporting spring (3) made of natural rubber and supporting a bearing core (7) introduced into the bearing cage. Fluid damping medium is introduced between the support spring and the bearing housing. An expanding chamber (8) defines a compensation chamber and an annular hydraulic duct. First and second rubber bars (4, 5) are provided between the bearing core and the bearing cage and integrated into the hydraulic duct. A third rubber bar (6) is not integrated into the hydraulic duct. An independent claim is also included for a method for manufacturing a hydraulically damping bushing.
