The invention concerns an axle ( 1 ) comprising a differential ( 6 ), two transmission lines ( 8 ) from the differential and adapted each to drive a drive wheel ( 2 ), members ( 4 ) for directional control of the drive wheels ( 2 ), each transmission line ( 8 ) including an input shaft ( 10 ) connected to the differential ( 6 ), an output shaft ( 12 ) connected to the corresponding drive wheel ( 2 ), a pivot ( 20 ) with axis oriented transversely to each of the input ( 10 ) and output ( 12 ) shafts, and a double torque transmitting joint ( 30 ) between the input shaft ( 10 ) and the output shaft ( 12 ). Said double-joint comprises two elementary joints ( 30 A, 30 B) axially connected to each other along a double-joint axis and including each an elementary break center. Each shaft ( 10, 12 ) defines a fixed position, along its axis (X-X, Y-Y), of the elementary break center of the corresponding joint ( 30 A, 30 B). Additionally, one at least of the two elementary joints ( 30 A, 30 B) is a joint freely sliding along the double-joint axis. |
