Abstract:
1. An elastic rubber bush bearing, comprising: an essentially cylindrical inner part; an outer sleeve surrounding said inner part; an elastomeric bearing body located in between said outer sleeve and said inner part, said elastomeric bearing body being connected to said inner part and to said sleeve by vulcanization; a reinforcing element arranged in the bearing body, said reinforcing element being provided as an intermediate tube in relation to said inner part and said outer sleeve, said reinforcing element having at least two longitudinal slots arranged distributed on the circumference of the intermediate tube and extending essentially in the axial direction with at least one of said longitudinal slots open toward one of two axial ends of the intermediate tube and at least another of said longitudinal slots open toward another of the two axial ends of the intermediate tub, and each of said respective longitudinal slots starting from the respective axial ends of the intermediate tube and extending in a direction of the respective other axial end to a slot end, spaced from said respective other axial end and at least beyond an axial middle of the intermediate tube, said intermediate tube further having elevation regions arranged distributed on the circumference, each of said elevation regions defining an axially extending jacket surface portion extending along a length of said intermediate tube to one of said axial ends with circumferentially spaced apart elevation regions extending respectively to each of said axial ends and with each said jacket surface portion being radially outwardly of an adjacent jacket region of said intermediate tube and an axial end of said jacket surface portion being radially outwardly of a remaining adjacent axial end thereof.
