driveshaft

Abstract

A drive shaft comprising a shaft element (4) and a coupling element (2) pivotable relative to the shaft element (4) by means of a swivel joint (2, 4C, 6), wherein the swivel joint comprises the coupling element (2), recesses (4C) of the shaft element (4) and several circumferentially distributed rolling elements (6) which engage in first recesses (4C) of the shaft element (4) and second recesses of the coupling element (2) in a rotationally fixed, positive-locking coupling of the shaft element (4) with the coupling element (2) such that the shaft element (4) is tiltable relative to the coupling element (2) and the shaft element (4) and the coupling element (2) are rotationally fixed to each other, characterized in that the shaft element (4) has a flange (4A) directly equipped with the first recesses (4C), wherein this flange (4A) further comprises several circumferentially distributed windows (4B).within each of which a fastening element (3) intended for further connecting the coupling element (2) projects.

Claims

A drive shaft comprising a shaft element (4) and a coupling element (2) pivotable relative to the shaft element (4) by means of a swivel joint (2, 4C, 6), wherein the swivel joint comprises the coupling element (2), recesses (4C) of the shaft element (4) and several circumferentially distributed rolling elements (6) which engage in first recesses (4C) of the shaft element (4) and second recesses of the coupling element (2) in a rotationally fixed, positive-locking coupling of the shaft element (4) with the coupling element (2) such that the shaft element (4) is tiltable relative to the coupling element (2) and the shaft element (4) and the coupling element (2) are rotationally fixed to each other, characterized in that the shaft element (4) has a flange (4A) directly equipped with the first recesses (4C), wherein this flange (4A) further comprises several circumferentially distributed windows (4B).within each of which a fastening element (3) intended for further connecting the coupling element (2) projects. Cardan shaft according to claim 1, wherein at least one fastening element (3) is a screw (3). Cardan shaft according to claim 2, wherein the screw (3) is made of a light metal, high-strength steel or plastic, in particular fiber-reinforced plastic. Cardan shaft according to one of claims 2 to 3, wherein the flange (4A) is fastened to the coupling element by means of screws (3) which are guided through the flange (4A) in bushings (5). Cardan shaft according to claim 4, wherein the bushings (5) are made of light metal, high-strength steel or plastic, in particular fiber-reinforced plastic. Cardan shaft according to one of the preceding claims, wherein the rolling elements (6) are rolling balls. Cardan shaft according to one of the preceding claims, wherein shaft element (4) and coupling element (2) are connected via a retainer (7) encompassing the flange (4A) of the shaft element (4), which is fixed to the coupling element (2) by means of further fastening means (8). Cardan shaft according to claim 7, wherein the retainer (7) is fixed to the coupling element (2) by means of screws (8) and supported by bushings (5). Cardan shaft according to one of the preceding claims, wherein the cardan shaft (1) is designed as a constant velocity joint shaft. Cardan shaft according to one of the preceding claims, wherein the rotationally fixed positive locking coupling of the shaft element (4) with the coupling element (2) via the rolling elements (6) is generated by a preload which clamps the coupling element (2) against the shaft element (4) via the rolling elements (6).
