BorgWarner TorqTransfer Systems has launched two new technologies for enhanced vehicle traction and stability.
The Pre-emptive Torque Management system’s differentiating feature is its ability to deliver torque before a wheel slips. A precise amount of torque is transferred prior to wheel rotation, through the use of electronic sensors and microcomputer controls. Managing the power between the front and rear wheels, and eliminating power to the rear wheels when it is not needed, results in better handling, traction and fuel economy.
The system continuously monitors dynamic torque capacity and adjusts capacity as required. It offers improved reliability and durability, as well as lower weight and cost. The system can be mounted anywhere between the output of the transmission and the input of the secondary axle. It is available in a variety of sizes to meet specific vehicle requirements, thus providing very flexible packaging benefits. Additionally, it can limit torque transfer to the power takeoff unit and secondary axle, permitting the use of lighter-weight and lower-cost components.
The InterActive Differential Control system uses electronic sensors and controls to deliver optimal biasing torque across the centre differential automatically. When the system senses that the wheels are slipping, it automatically transfers power to the tractive wheels through the centre differential. When the slipping stops, biasing to the tractive wheels is reduced or eliminated — again, enhancing vehicle handling and traction through the management of power between the front and rear wheels.
Both systems deliver the requested amount of torque in response to electronic signals provided by one or more of the vehicle’s traction and/or stability control systems. They are both fully interactive with, and work in conjunction with, other vehicle systems including antilock braking systems, electronic traction control, electronic stability programmes and active suspension programs. Both systems are pre-tested, and offer the customer benefits such as improved vehicle integration with no separate electronics to package, as well as reduced wiring harness complexity.
