| 摘要 |
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 (30A, 30B) 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 (30A, 30B). Additionally, one at least of the two elementary joints (30A, 30B) is a joint freely sliding along the double-joint axis. |
