Motor vehicle with disconnectable all-wheel drive system |
摘要 |
A vehicle with primary and secondary drivelines and a power take-off unit (PTU). The primary driveline has a first differential that is configured to distribute power to a first set of wheels. The PTU has a PTU input, a PTU output and a synchronizer for selectively de-coupling the PTU output from the PTU input. The secondary driveline is configured to distribute power to a second set of wheels and has a propshaft, a second differential, a pair of half-shafts and at least one torque transfer device (TTD). The propshaft transmits rotary power between the PTU output and an input of the second differential. The half-shafts are rotatably coupled to an output of the second differential and are configured to transmit rotary power to the second set of wheels. The at least one TTD is configured to selectively inhibit torque transmission through the second differential to the second set of wheels.
