Patent ID: 8826759

Claim:
A transmission shift mechanism actuating apparatus for actuating at least one shift mechanism of a transmission for shifting at least one gear wheel on a hollow shaft ( 2 ), the transmission shift mechanism actuating apparatus comprising; a hollow shaft ( 2 ); at least one gear wheel mounted on the hollow shaft; at least one actuator module ( 1 ) at least partially positioned in the hollow shaft ( 2 ) and which comprises at least one actuator ( 4 , 5 ); the at least one actuator ( 4 , 5 ) being at least partially positioned in the hollow shaft ( 2 ), and applying an axially directed actuating force on and enabling internal axial actuation of at least one coupling element ( 10 , 11 , 11 ′), and being operationally connectable with the at least one coupling element ( 10 , 11 , 11 ′); the at least one coupling element ( 10 , 11 , 11 ′) extending radially inward to an inner diameter of the hollow shaft ( 2 ); and the actuator module ( 1 ) having at least one axial assembly guide as an open passageway for the coupling element ( 10 , 11 , 11 ′) when the actuator module ( 1 ) is axially inserted into the hollow shaft ( 2 ).
