Driveline for the reciprocating knives of a combine header

A combine header comprising a header frame and a driveline configured to drive a reciprocating movement of a set of knives mounted at a front of the combine header, the driveline comprising:

• a transverse drive shaft at a back of the combine header;
• a bevel gearbox having an inlet axle that is coupled to the transverse drive shaft, and an outlet axle;
• a lateral drive shaft arranged laterally with respect to the header frame, the lateral drive shaft having a first end and a second end;
• and
• a transmission having an inlet axle and an outlet axle, the outlet axle being coupled to the set of knives;
• wherein:
• the lateral drive shaft is coupled at its first end to the outlet axle of the bevel gearbox via a first universal joint;
• the lateral drive shaft is coupled at its second end to the inlet axle of the transmission via a second universal joint;
• the driveline comprises a flywheel that is integral with or fixed to the inlet axle of the transmission, the flywheel being configured to perform a stabilizing function to stabilize rotation of the lateral drive shaft;
• the second universal joint comprises a first fork attached to the lateral drive shaft, a second fork oriented orthogonally with respect to the first fork and attached to the inlet axle of the transmission and a cross-piece, wherein the first and second forks are pivotable relative to legs of the cross-piece;
• the second fork is integral with or fixed to a flange that is removably attached to a surface of the flywheel that faces the lateral drive shaft;
• and
• the flange is configured to contribute to the stabilizing function of the flywheel when the flange is attached to the surface.
