Active On Demand Coupling
The main role of Active On demand Coupling and the control module for all wheel drive (Differential Electronic Module) is to regulate the all wheel drive function, i.e. the distribution of drive between the front and rear axles. The system consists of a coupling assembly with a mechanical, hydraulic and electronic component. The coupling is located on the rear axle, between the axle gear and the propeller shaft. The mechanical and hydraulic component is driven by the rotation of the propeller shaft.
The Active On Demand Coupling provides the following characteristics:
- Permanent all wheel drive with electronic control of torque transfer
- Driving characteristics similar to all wheel drive
- Fast reaction
- No wind-up forces during low speed maneuvering
- The system is not sensitive to differences between tires (when driving with a spare wheel for example)
- The system is not sensitive to being towed with one axle raised
- The system is not sensitive to brake tests on a chassis dynamometer
