VEHICLE DRIVE SYSTEM, ALL WHEEL DRIVE AXLE AND METHOD OF PROVIDING AN ALL WHEEL DRIVE AXLE

WIPO Patent Application WO/2018/087375

A3

A vehicle driveline system for a vehicle, said system comprising a differential (100) having a differential housing (106) connectable to an engine via a pinion (103), and two output shafts (111, 112) being connectable with respective wheel axles, and an electrical motor (180) being selectively connected to the differential housing (106). Said differential housing (106) extends into a hollow shaft (113) and the differential housing (106) comprises an outer gearing (104) configured to mesh with the pinion (103) and an inner gearing (107) being connected with the output shafts (111, 112). The vehicle driveline system further comprises a first reduction gearing (160) connected to the hollow shaft (113) and an actuator arrangement (190) arranged between the differential housing (106) and the first reduction gearing (160). The actuator arrangement is configured to selectively transfer torque in any of the following modes: i) a first drive mode in which the actuator arrangement (190) is configured to be actuated to allow for torque transfer from the electrical motor (180) to the differential housing (106) only via the hollow shaft (113). ii) a second drive mode in which the actuator arrangement (190) is configured to be actuated to allow for torque transfer from the electrical motor (180) to the hollow shaft (113) via the first reduction gearing (160).
