там стоит AWD раздатка-без возможности управления...
The New Venture Gear model NVG 126 RPO NP4 transfer case is a one speed automatic,
active, transfer case. The NVG 126 provides only one mode, Auto 4WD, and is
transparent to the operator. The active transfer case provides the benefits of
on-demand torque biasing, wet clutch and easy vehicle tuning through software
calibrations. The software calibrations allow more features, such as exible adapt ready
position and clutch pre-load torque levels. The technology allows for vehicle speed
dependent clutch torque levels to enhance the performance of the system. For example,
the system is calibrated to provide 0 - 7 Nm (0 - 62 inch lbs.) of clutch torque during
low speed, low engine torque operation, and predetermined higher torque for 32 km/h
(20 h) and greater. This prevents crow-hop and binding at low speeds, and provides
higher torque biases at higher vehicle speeds, to enhance stability.
