Development of NexTrac Electronic Driveline Coupling for Front-Wheel-Drive-Based, All-Wheel-Drive Applications

摘要

There is a significant market shift taking place between RWD- and FWD-based AWD segments. The industry is experiencing a tremendous growth of FWD-based AWD with the majority of new FWD platforms offering an AWD derivative. This has created demand for higher performing, cost-effective, electronically controlled on-demand AWD couplings. To meet this demand BorgWarner, has developed a new electronically controlled driveline coupling called NexTrac. NexTrac is a significant departure from conventional electro-magnetically actuated FWD/AWD couplings prevalent in the market today. The most distinct new feature is the direct actuation of the primary clutch by an electro-mechanical system using organic friction material for the primary clutch plates instead of steel. This, and other features give NexTrac superior lifetime NVH performance and cost-effective driveline integration.
