Patent number: 11104225Abstract: A transfer case with an actuator for operating a two-speed transmission (i.e., range mechanism) and a clutch (i.e., mode mechanism). The actuator employs a motor-driven cam structure that coordinates the movement of a first fork, which is associated with the range mechanism, and a second fork that is associated with the mode mechanism. A resilient coupling is employed to provide compliance between the motor and the cam structure in the event that tooth-on-tooth contact inhibits the range mechanism from changing from a high-range mode and a low range mode or tooth-on-tooth contact inhibits the mode mechanism from changing between a two-wheel drive mode and a four-wheel drive mode. A sensor target and sensor are employed to identify the rotational positioning of the cam structure placement, which is indicative of the modes in which the transmission and the clutch are operating.Type: GrantFiled: April 9, 2018Date of Patent: August 31, 2021Assignee: BorgWarner Inc.Inventors: Travis J.

Patent number: 11078812Abstract: A continuously variable friction drive is used to phase a cam plate attached to the camshaft relative to a sprocket plate driven by the crankshaft. Discs are received within the cavity between the sprocket and cam plate. The discs are free to rotate about an axis of rotation, and is fixed relative to the cam and the sprocket, so that when the sprocket plate rotates, the cam plate is rotated by the discs in the opposite direction. The axis of rotation of the discs can be tilted by an actuator, so that the discs themselves contact the plates at different distances from their axes of rotation, which changes the speed of rotation of one plate relative to the other. When the speed of rotation of the crank and cam differ, the phase angle between the two shafts is changed.Type: GrantFiled: July 7, 2016Date of Patent: August 3, 2021Assignee: BorgWarner Inc.Inventor: Chad McCloy
