This book presents analytical and experimental methods and achievements in the design of mechanical and mechatronic driveline systems. These include power dividing units, such as symmetric and non-symmetric, open and lockable differentials, various limited slip differentials, and no-spins and viscous clutches. Addressing vehicle dynamics and performance issues, the authors propose an approach to designing vehicle driveline systems based on determining optimum power distributions to the drive wheels. The text also provides logic control algorithms to control vehicle power dividing units and designs of torque/power managing devices. Each chapter includes problems.
