Abstract
At least some implementations of a transmission gear shifter include a first shift member having a body rotatable about an axis among multiple positions, a retainer movable relative to the body, an actuator coupled to the retainer and a second shift member coupled to the first shift member. The retainer is movable between a first position in which the retainer prevents movement of the body and a second position in which the retainer permits movement of the body. The actuator drives the retainer between the first position and second position. And the second shift member is driven by the actuator between first and second positions to rotate the body. In at least some implementations, the second shift member is engaged by the retainer and driven by movement of the retainer.
Claims20
A shifter for a vehicle transmission, comprising:
- a first shift member having a body rotatable about an axis among multiple positions;
- a retainer movable relative to the body, the retainer being movable between a first position in which the retainer prevents movement of the body and a second position in which the retainer permits movement of the body;
- an actuator coupled to the retainer to drive the retainer between the first position and second position;
- and
- a second shift member coupled to the first shift member and driven by the actuator between first and second positions to rotate the body.
A shifter for a vehicle transmission, comprising:
- a first shift member having a body rotatable about an axis between a park position, a reverse position, a neutral position and a drive position, and the first shift member has at least one shifter control feature;
- a retainer movable along a linear path relative to the body and having at least one retainer control feature, the retainer being movable between a first position in which the retainer control feature overlaps the shifter control feature when the shifter is in the park position to prevent rotation of the body, and a second position in which the retainer control feature does not overlap the shifter control feature and rotation of the body is permitted;
- an actuator coupled to the retainer to drive the retainer between the first position and second position;
- and
- a second shift member coupled to the first shift member so that the second shift member is in a first position when the first shift member is in the park position and the second shift member is in a position different than the first position when the first shift member is not in the park position, and the second shift member has a portion engageable by the retainer as the retainer moves from the second position to the first position so that when the retainer is in the first position the second shift member is in the first position and the first shift member is in the park position.
