Sleeve, particularly a rod sleeve

Abstract

A rod sleeve, at least comprising a core having a core hub that has two faces and a core pin, which extends in the direction of a longitudinal axis Y. This core pin projects over both faces of the core hub while forming two connecting journals. The sleeve also comprises an outer sleeve and an elastic layer located between the core hub and the outer sleeve. The core hub and the core pin form a one-piece core system that is in the form of two parts with regard to a normal axis X to the longitudinal axis Y. Both core halves are assembled with interference fit via an insertion-slot system. The core hub between its two faces undergoes a tapering with an angle change α, whereby the respective contact surfaces of the core hub and of the outer sleeve extend in a manner that essentially corresponds to the elastic layer. The outer sleeve and the elastic layer are provided in two parts with regard to the normal axis X to the longitudinal Y. Both sleeve halves are assembled with interference fit by means of an insertion-slot system, whereas both elastic layer halves are placed at a distance L 1 from one another.
