ABSTRACT:
The protective casing includes a system of telescopic tubes (26 and 27) that cover a pair of telescopic tubular elements (13 and 14) connecting two universal joints (9 and 11) on a transmission shaft. The inner telescopic tube (26) is fitted with a grease nipple (35) that is connected via a tube (39) to a chamber formed by a bushing (41) and a sealing ring (63). A suitable lubricant can be injected into the chamber, from the exterior, via the grease nipple (35), so that the telescopic tubular elements (13 and 14) can be kept lubricated without this requiring the transmission being uncoupled.
