Patent ID: 8870489

Claim:
A device ( 1 , 1 ′) for a rotationally fixed connection of a drive-effective pin ( 3 ) of a gearbox to an articulated body ( 2 ) of a drive coupling of a drive shaft comprising: a pin ( 3 ) exhibiting an outer external toothing ( 11 ); an articulated body ( 2 ) exhibiting an internal axial toothing ( 8 ) in a hollow cylindrical opening ( 9 ), wherein the outer external toothing ( 11 ) and the internal axial toothing ( 8 ) correspond to each other and are able to mesh with one another, an axially displaceable bushing ( 12 ) arranged on the pin ( 3 ), wherein the axially displaceable bushing ( 12 ) makes possible an axial securing of the articulated body ( 2 ) and the pin ( 3 ), which bushing ( 12 ) can be positioned or fastened to a remote track connecting portion ( 4 ) of the articulated body ( 2 ), wherein a radially inner cylindrical surface ( 19 ) of the bushing ( 12 ) and a radially outer cylindrical surface ( 20 ) of the articulated body ( 2 ) are connected force matchingly or shape matchingly, wherein the pin ( 3 ) has a displacement portion ( 10 ) and an end portion with the external axial toothing ( 11 ), a circumferential groove ( 6 , 14 ) formed between the displacement portion ( 10 ) and the external axial toothing ( 11 ), wherein a radial inner side of a circlip ( 13 , 24 ) is arranged in the circumferential groove ( 6 , 14 ); wherein a radial depth of the circumferential groove ( 6 , 14 ) in the pin ( 3 ) is smaller than half a radial extension of a material of the circlip ( 13 , 24 ), wherein a radial outer side of the circlip is directly abutted on a first axial side directed away from the connecting portion of the articulated body by an end face of the bushing directed towards the connecting portion of the articulated body and on an oppositely disposed second axial side directed towards the connecting portion by an end face of the articulated body.
