BorgWarner says it is supplying two versions of its electro-hydraulically actuated, all-wheel drive (AWD) coupling for the new Volkswagen Crafter. One with a differential lock control at the rear axle, the other without this feature. The unit distributes torque between the front and rear axle and the company claims this compact, lightweight AWD coupling provides high torque accuracy for improved fuel economy.
To meet the OEM’s requirements BorgWarner says it added an optional differential lock control with a new electronic control unit (ECU) to its AWD coupling. The ECU features adaptable vehicle dynamics software which it’s claimed controls the optional differential lock to allow smooth starts by improving traction on split-friction road surfaces which in turn reduces tyre wear.
