  • 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.
