Free-wheel cage ring with centrifugal-force lifting

Abstract

The invention relates to a one-way clutch retainer, which comprises two circular flanged disks (1,2; 11,12); the flanged disks are connected with each other and arranged with an axial gap; action bodies (4; 14) are disposed there between; the action bodies can be arranged in the retainer by a swinging way and is pre-tightened on the joint direction by a spiral torsion spring; the action bodies perform the acting swinging motion on the separation direction against the spring under the effect of centrifugal force; at least two guiding surfaces (5c,5d; 15) are arranged for each action body in its axial extension; a guiding surface is joined on the regions on the end peripheries of the action bodies, can guide the action body at least on the circumferential direction of the flanged disk and has a fracture on at least the radial inner side; the action body is passed throught the fracture and is extended towards an action surface on the radial inner side; the axial length of the action surface on the radial inner side of the action body is equal to the total length of the action body. According to the invention, The guiding surfaces are each formed integrally by recesses on opposite end faces of the flanged disks.

Description

technical field [0001] The invention relates to a one-way clutch (ring) cage according to the preamble of claim 1 The one-way clutch retainer comprises two substantially radially extending annular end pieces / edge pieces, said end pieces being connected to each other forming an axial gap, with a plurality of functions between said end pieces body / wedge, the action body is arranged in a swingable manner in the cage and is prestressed in the engagement direction by at least one helical torsion spring; Oscillating motion acting in the direction of separation. At least two guide surfaces are assigned to each active body in its axial extent, which engage on the opposite end peripheral regions of the active body, at least in the circumferential direction of the end piece Guide the actor above. Background technique [0002] In the case of freewheels with centrifugal disengagement, it is known that during freewheeling the cage moves together with the freewheel outer ring, while t...

Problems solved by technology

This is of great importance, since even a small amount of material wear on the active body can cause uneven action which impairs functionality and eventually lead to freewheel failures which can be dangerous for the operator
