Patent ID: 7931556

Claim:
An automatic transmission ( 1 ) comprising at least one planetary stage ( 2 ) and at least one gear shifting element ( 3 ), the gear shifting element ( 3 ) being axially arranged directly adjacent to the planetary stage ( 2 ), a piston-cylinder arrangement ( 4 ) actuating the gear shifting element ( 3 ), the planetary stage ( 2 ) comprising a ring gear ( 5 ), a sun gear ( 6 ) and a planet carrier ( 7 ), on which planet gears ( 8 ) are rotatably mounted, the planet carrier ( 7 ) being permanently connected, in a fixed manner to a transmission shaft ( 9 ), and a pressure medium being conducted to a pressure chamber ( 10 ) of a cylinder ( 11 ) of the piston-cylinder arrangement ( 4 ) through an axial bore ( 12 ) in the transmission shaft ( 9 ) and a bore ( 13 ) in the planet carrier ( 7 ), the bore ( 13 ) in the planet carrier ( 7 ) supplying the pressure medium to the pressure chamber ( 10 ), and the bore ( 13 ) in the planet carrier ( 7 ) extending through the planet carrier ( 7 ) both radially and axially obliquely with respect to an axial bearing ( 14 ) of the transmission shaft ( 9 ).
