Abstract
The wide-angle constant velocity joint (100) includes: a central core (101) forming respective inner yokes (24, 25) for connection and in which there is housed a guide disc (11); and outer yokes (103, 105). The central core (101) forms a lubricant reservoir (1) in communication with an annular seat (7) in which the guide disc (11) is slidingly received.
Claims21
A wide-angle constant velocity joint comprising:
- a first outer yoke and a second outer yoke;
- a first spider and a second spider hinged to the first outer yoke and to the second outer yoke, respectively;
- a central core, forming a first inner yoke and a second inner yoke, wherein said first inner yoke and said second inner yoke are connected through the first spider and the second spider to the first outer yoke and to the second outer yoke, respectively;
- a guide disc engaged in an annular seat formed in the central core and coaxial to a rotation axis of the central core, spherical heads of the first outer yoke and of the second outer yoke being engaged with said guide disc;
- a lubricant reservoir in the central core, in communication with said annular seat;
- and
- a dosing system for dosing the lubricant from the reservoir to the annular seat, wherein the dosing system comprises a dosing disc interposed between the reservoir and the annular seat;
- wherein the dosing disc comprises an inlet hole, an outlet hole and a slot extending in a thickness of the dosing disc and that places the inlet hole in communication with the outlet hole;
- and wherein the inlet hole and the outlet hole are spaced from each other in at least one of a tangential direction and a radial direction, so as to define a dispensing path of the lubricant along said slot from the inlet hole to the outlet hole.
