A protective device (1) for universal joint transmissions, comprising at least two coaxial tubular protective elements (10, 20), which are associated telescopically with each other and are adapted to accommodate the telescopic shafts (2, 3) of a universal joint transmission, the two tubular protective elements (10, 20) each comprising, at their opposite ends, a protective hood (4), adapted to surround a joint (5) of the universal joint transmission, the two tubular protective elements (10, 20) each comprising a locator flange (30, 40) associated rigidly with the tubular protective element (10, 20), the protective hood (4) comprising:
- a coupling flange (50), which is coaxial to the locator flange (30, 40) and is adapted to abut against the locator flange (30, 40),
- a cylindrical accordion portion (60) supported by the coupling flange (50),
- at least one fastening element (70) adapted to fasten the coupling flange (50) on the locator flange (30, 40),
the protective device (1) also comprising at least one supporting ring (80), which comprises engagement means (81) for the engagement of the supporting ring (80) with the locator flange (30, 40), which is accommodatable rotatably in an annular seat (6) provided at the outer surface of the hub of the fork (8) of the joint (5) in order to support the entire protective device (1). |
