  • Power transfer mechanism for 4WD vehicles with low effort mode shift system
    Patent number: 9216649
    Abstract: A power transfer mechanism for a four-wheel drive vehicle includes a first shaft for transferring torque to a first driveline, a second shaft for transferring torque to a second driveline, and a transfer mechanism driving the second shaft. A mode clutch drivingly connects the first shaft to the transfer mechanism and includes a clutch gear-driven by the transfer mechanism and a mode sleeve. A sprocket associated with the transfer mechanism has internal spline teeth meshed with external spline teeth on the second shaft with a predetermined amount of backlash therebetween. A ball cam mechanism centers the backlash and permits relative rotation of the transfer mechanism and the mode sleeve to circumvent a blocked mode shift.

  • Transfer case with dual chain transfer mechanism
    Patent number: 7231848
    Abstract: A transfer case for use in a motor vehicle to selectively transfer drive torque from a powertrain to first and second pairs of wheels. The transfer case includes an input shaft driven by the powertrain and an output shaft selectively driven by the input shaft. A transfer mechanism is operably disposed between the input shaft and the output shaft to transfer drive torque from the input shaft to the output shaft. The transfer mechanism includes a first chain that is selectively driven by the input shaft and a second chain that is driven by the first chain and that transfers drive torque to the output shaft.
