Universal joint with oil-bath clutch torque limiter and drive shaft comprising said joint

A system comprising a universal joint and a protective hood for the universal joint, adapted to be fixed to a stationary component;

• wherein the universal joint comprises:
• a first yoke;
• a second yoke;
• a spider connecting the first yoke and the second yoke;
• a hub coaxial to the first yoke;
• a torque limiter interposed between the hub and the first yoke;
• and
• wherein:
• said torque limiter comprises a clutch contained in an oil-bath chamber;
• the first yoke is integral with a closing flange of the oil-bath chamber;
• the oil-bath chamber is closed, on a side opposite the closing flange, by a closing body through which the hub extends;
• the clutch comprises:
• a series of first clutch discs torsionally connected to the hub, a series of second clutch discs torsionally connected to the first yoke, and at least one elastic member which presses the first clutch discs and the second clutch discs against one another;
• the first clutch discs and the second clutch discs are dipped in the oil bath and are interspersed with one another;
• and the hub is supported in the oil-bath chamber by means of a first bearing and a second bearing.

A drive shaft comprising:

• a telescopic shaft with a first end and a second end;
• a first universal joint associated with the first end of the telescopic shaft;
• and
• a second universal joint associated with the second end of the telescopic shaft;
• wherein one of said first universal joint and second universal joint a first yoke;
• a second yoke;
• a spider connecting the first yoke and the second yoke;
• a hub coaxial to the first yoke;
• and a torque limiter interposed between the hub and the first yoke;
• wherein said torque limiter comprises a clutch contained in an oil-bath chamber;
• wherein the first yoke is integral with a closing flange of the oil-bath chamber;
• wherein the oil-bath chamber is closed, on a side opposite the closing flange, by a closing body through which the hub extends;
• wherein the clutch comprises:
• a series of first clutch discs torsionally connected to the hub, a series of second clutch discs torsionally connected to the first yoke, and at least one elastic member which presses the first clutch discs and the second clutch discs against one another;
• wherein the first clutch discs and the second clutch discs are dipped in the oil bath and are interspersed with one another;
• and wherein the hub is supported in the oil-bath chamber by means of a first bearing and a second bearing.
