  • Patent number: 12253164
    Abstract: The present teachings generally provide for an actuator assembly to move between a decoupled position, and a coupled position. The actuator assembly includes a shift assembly including a gear connected to the motor, an input member in communication with the gear configured to transition between a first position and a second position; an output member operatively connected to the input member and configured to move a distance defining a stroke length between a disengaged position and an engaged position; and a biasing member connecting the input member to the output member. The input member rotates from the first position to the second position relative to the output member, increasing a tension of the biasing member due to an interference causing a blocked condition. The biasing member rotates the output member in a releasing condition upon clearance of the interference such that the output member rotates through the stroke length.

  • Patent number: 11971073
    Abstract: A rotary shifter assembly for changing gears in a vehicle transmission includes a shaft (16) that is rotatably supported in a housing (12) and movable between radial positions for indicating a gear change. A shift knob (10) is coupled to a first end of the shaft for actuation by a user. A plurality of flexible locking fingers (40) extend from the second end, and an overload wheel (18) is disposed about the fingers. The fingers engage the wheel to couple it with the shaft for concurrent rotation. A locking mechanism (64) engages the wheel to selectively prevent and allow concurrent rotation of the wheel and shaft during normal operation. The fingers move relative to the wheel to permit temporary rotation of the shaft relative to the wheel when a force applied to the shaft is beyond a maximum torque threshold, and automatically return to concurrent rotation with the wheel once the force is below the threshold.
