Abstract
A system having a pair of axle shafts; an input shaft for transmitting torque; and a differential for transmitting motion from the input shaft to the axle shafts and in turn presenting a planet carrier angularly integral with the input shaft, and a pair of sun gears; the system also presenting a first clutch interposed between each axle shaft and a respective sun gear, a second clutch interposed between each axle shaft and the planet carrier; and a device for controlling the clutches and continuously varying distribution of the torque between the axle shafts.
Claims9
A system (1;
- 31) for instantaneously controlling torque distribution between wheels of a common vehicle axle, the system (1) comprising a pair of axle shafts (3, 4), each connected angularly integral with a respective drive wheel (5) on a vehicle;
- an input shaft (2) for transmitting torque (M);
- and a differential (6) for transmitting motion from said input shaft (2) to said axle shafts (3, 4);
- the differential (6) presenting a planet carrier (7) angularly integral with said input shaft (2), and a pair of sun gears (8);
- comprising:
- first releasable angular connecting means (12) interposed between each said axle shaft (3, 4) and a respective said sun gear (8);
- and second releasable angular connecting means (13) interposed between each said axle shaft (3, 4) and said planet carrier (7);
- control means (14) being provided for controlling said first and second angular connecting means (12, 13) to continuously vary distribution of said torque (M) between said axle shafts (3, 4).
