Patent ID: 8001865

Claim:
An electromagnetic shifting device for a transmission ( 1 ) comprising: an electronic control unit ( 22 ) and first and second toothed gear wheels ( 6 , 7 ), which are rotatably supported on a vehicle transmission shaft ( 2 ) for rotation about an axis ( 3 ), the first and second toothed gear wheels ( 6 , 7 ) forming a gear stage when rotationally fixed to the transmission shaft ( 2 ) by axial movement of a shifter pawl ( 4 ) along the axis ( 3 ) of the transmission shaft ( 2 ), each of the first and second toothed gear wheels ( 6 , 7 ) having radially inwardly facing teeth ( 8 ), the shifter pawl ( 4 ) having mating radially outwardly facing teeth ( 5 ) and being rotationally fixedly supported on the transmission shaft ( 2 ) and being axially movable along the axis ( 3 ) of the transmission shaft ( 2 ) by an electric linear motor ( 12 ) comprising a primary portion ( 14 ) and a secondary portion ( 13 ), one of the primary and the secondary portions ( 13 , 14 ) of the electric linear motor ( 12 ) being arranged within the transmission shaft ( 2 ) and the other of the primary and the secondary portions ( 14 , 13 ) of the electric linear motor ( 12 ) being arranged in the shifter pawl, wherein the first and the second toothed gear wheels are both rotatably supported by and axially fixed on the transmission shaft, one of the primary portion and the secondary portion of the electric linear motor is a positionally fixed component, and the positionally fixed component is located within the transmission shaft ( 4 ).
