Abstract:
A constant velocity universal joint comprising:a hollow outer part (1) with an inner face (2) provided with outer tracks (3) distributed around a first longitudinal axis (4);a first attaching element (5) securely connected to said outer part (1), and which closes said outer part (1) and has a sliding face (10) on which said first longitudinal axis (4) is positioned perpendicularly;an inner part (12) having an outer face with inner tracks (14) circumferentially distributed around a second longitudinal axis (13) as to correspond to said outer tracks (3), and whose outside comprises a spherical guiding face (15) and a spherical control face (17) separated therefrom;a second attaching element (18) connected to said inner part (12) in a rotationally fixed way;balls (23) which are each accommodated in said pairs of outer tracks (3) and inner tracks (14);a cage (24) which, by means of a hollow spherical supporting face (25), is guided on said spherical guiding face (15) of said inner part (12) said cage (24) having an outer face (26) and having windows (27) for guiding said balls (23);a control element (29) which, by means of a contact face (30), with reference to the first longitudinal axis (4), is radially adjustably supported on said sliding face (10) of said first attaching element (5) associated with said outer part (1), and which comprises a hollow spherical seat face (31), with said inner part (12), by means of said control face (17), being supported on said seat face (31) and with said cage (24), with said outer face (26), being held at a distance from said inner face (2) of said outer part (1) and with said control element (29) comprising a central aperture (32), and further having a sealing sleeve (33) which, at one end, is secured to said outer part (1) and at a second end to said second attaching element (18); andsaid first attaching element (5) having a first chamber (9) open towards said contact face (30) of said control element (29), at least one of said inner part (12) and said second attaching element (18) connected to said inner part (12), and having a second chamber (20) open towards said seat face (31), and that both chambers (9, 20) communicate with one another through said central aperture (32) and are filled with lubricant.
