Patent ID: 7026770

Claim:
An actuating apparatus ( 1 ) for the impingement of at least two shift elements ( 42 , 44 ) that are spaced apart from each other, each having at least a first engagement area ( 50 , 52 ) for its actuation, comprising: a drive shaft ( 10 ) arranged to be driven by a motor in both rotational directions; the drive shaft ( 10 ) having a first thread profile ( 20 ); a positioning device ( 28 ) screwed onto the first thread profile ( 20 ) of the drive shaft ( 10 ) via a second thread profile ( 22 ) that is complementary to the first thread profile ( 20 ); and, a control element ( 30 ) that is connected to the positioning device ( 28 ) in a rotationally fixed manner which causes the positioning device ( 28 ) to be turned with the drive shaft ( 10 ) when the drive shaft ( 10 ) turns in a first rotational direction, at least one second engagement area ( 54 ) provided on the positioning device ( 28 ) being positioned on at least one first engagement area ( 50 , 52 ) of at least one shift element ( 42 , 44 ); wherein the control element ( 30 ) controls an axial displacement of the positioning device ( 28 ) in relation to the drive shaft ( 10 ) when the drive shaft ( 10 ) turns in a second rotational direction that is opposite the first rotational direction and with it an actuation of the at least one shift element ( 42 , 44 ), on whose first engagement area ( 50 , 52 ) the second engagement area ( 54 ) is positioned.
