Rotary shifter assembly
First Claim
1. A shifter assembly for changing gears in a vehicle transmission, said shifter assembly comprising:
- a housing;
a shift rod rotatably supported in said housing and selectively movable between a plurality of radial positions;
a disc in rotational communication with said shift rod for concurrent movement with said shift rod between said radial positions with said disc defining a plurality of elongated gates each defining respective spaced first and second ends; and
a plurality of solenoids disposed in said housing adjacent said disc with each of said solenoids having a plunger selectively movable between a first position spaced from said disc and a second position disposed within one of said gates;
said gates being spaced equally from each other and all of said gates of said shifter assembly being radially aligned about a common reference circle such that said plungers are located about said common reference circle, with rotation of said shift rod being selectively limited by at least one of said plungers in said second position engaging one of said ends of one of said gates; and
including G gates and S solenoids wherein G refers to the quantity of said plurality of gates and S refers to the quantity of said plurality of solenoids, wherein said shift rod is selectively movable between N discrete radial positions, wherein N=[(G)*(S)], and wherein N<
30 discrete radial positions.

Abstract
A shifter assembly for changing gears in a vehicle transmission, including a housing and a shift rod rotatably supported in the housing. The shift rod is selectively movable between a plurality of radial positions. A disc is in rotational communication with the shift rod for concurrent movement between the radial positions. The disc defines a plurality of gates each having respective first and second ends. A plurality of solenoids are disposed in the housing adjacent the disc. Each of the solenoids has a plunger selectively movable between a first position spaced from the disc and a second position disposed within one of the gates. The gates are spaced equally from each other and are radially aligned about a common reference circle. Rotation of the shift rod is selectively limited by at least one of the plungers in the second position engaging at least one of the ends of the gates.

21. A shifter assembly for changing gears in a vehicle transmission, said shifter assembly comprising:
-
a housing; a shift rod rotatably supported in said housing and selectively movable between a plurality of radial positions; a disc in rotational communication with said shift rod for concurrent movement with said shift rod between said radial positions, with a plurality of elongated arcuate slots formed in said disc, each of said arcuate slots having a closed periphery, and each of said arcuate slots defining respective spaced first and second ends; a plurality of solenoids disposed in said housing adjacent said disc with each of said solenoids having a plunger selectively movable between a first position spaced from said disc and a second position disposed within said closed periphery of one of said arcuate slots; said arcuate slots being spaced equally from each other and all of said arcuate slots of said shifter assembly being radially aligned about a common reference circle such that said plungers are located about said common reference circle, with rotation of said shift rod being selectively limited by at least one of said plungers in said second position engaging one of said ends of one of said arcuate slots.
