Abstract:
A hydraulic damping bush for damping loads in a main loading direction, comprising:inner and outer sleeves together enclosing a space and defining a longitudinal direction; a resilient mounting assembly disposed between said inner sleeve and said outer sleeve; at least two end caps connecting said inner sleeve to said outer sleeve, capping said space enclosed by said inner sleeve and said outer sleeve, being formed separately from said resilient mounting assembly, and each having a rigid member mutually overlapping in a direction perpendicular to said main loading direction to define an overlapping region; two chambers charged with a hydraulic damping fluid; and a transfer duct interconnecting said two chambers and having an inlet, an outlet, and a main loading direction oriented parallel to said longitudinal axis of said inner sleeve and said outer sleeve; each of said chambers being defined by one of said resilient mounting assembly, a component adjoining the resilient mounting assembly, and one of said end caps; and said inlet and said outlet of said transfer duct being located in said overlapping portion of said rigid members of said resilient mounting assembly and said end caps.
