Patent ID: 10293686

Abstract:
A vehicle comprising a prime mover, first and second groups of wheels, and a driveline configured to connect the prime mover to the wheels. The driveline includes an auxiliary driveline comprising a driveshaft and drive means between the driveshaft and the second group of wheels, the drive means being operable to connect the second group of wheels to the driveshaft when the driveline transitions between first and second modes. The drive means has an input portion, an output and first and second releasable torque transmitting means coupled in series therebetween. The first releasable torque transmitting means is operable to allow slip between the input and output to modulate an amount of torque transmitted therebetween, The second releasable torque transmitting means is operable between a first condition in which an input portion is isolated from an output portion and a second condition in which the input and output portions are directly coupled.
