The holding element 14 is annular and has along its outer circumference evenly distributed more, in the present embodiment four, second elastic elements 15 on. The retaining element is between the sliding sleeve 2 ' and the connection area 23 of first shaft element 3 and second shaft element 4 firmly on the first shaft element 3 arranged. The second elastic elements 15 are as spring tongues 15 ' trained and act in the radial direction on the unlocking 16 ( 12b ).

The holding element 14 is for example designed as a sheet metal part ( 12b ).

The unlocking element 16 is substantially annular and axially fixed but rotatable on the shift sleeve 2 ' arranged. The sliding sleeve 2 ' and the unlocking element 16 are arranged coaxially.

The unlocking element 16 has a first gate section 17 and a second gate section 18 on. The first set of scenes 17 forms from several spring bags 25 off, taking on the spring bags 25 bevels on both sides, also chamfers 26 called, are formed. The second gate section is as a tooth profile 18 ' educated ( 9a . 9b . 11a . 11b . 13a and 13b ).

The unlocking element 16 is for example designed as a sintered part ( 13a ).

By the bias of the spring tongues 15 ' becomes the unlocking element 16 from the rotating first shaft member 3 rotationally moved. The first wave element 3 , the shift sleeve 2 ' and the unlocking element 16 rotate uniformly around the longitudinal axis 21 , The electromagnetic actuator 5 is de-energized and the actuator 10 is located in an actuator center position 6 with sufficient clearance to the swash plate 19 ' as well as to the second gate section 18 of the unlocking element 16 ,

The in 6 schematically represented operation corresponds to the first switching operation, namely a movement of the shift sleeve 2 ' from a first switching position to a second switching position.

Will be the first coil of the bidirectionally effective electromagnetic actuator 5 energized, so experiences the actuator 10 According to the electromagnetic force effect a lifting movement in the direction of the longitudinal axis 21 of the first shaft element 3 and brings the actuator 10 , more precisely, the first interventional process 11 of the actuating element 10 , in engagement with a third gate section 19 at the outer circumference of the sliding sleeve 2 ' is trained.

The third scene section 19 is in the present embodiment as a swash plate 19 ' formed on the sliding sleeve 2 ' is fixed. A direct training of the third stage section 19 on the outer periphery of the shift sleeve 2 ' is also conceivable.

By the rotation of the first shaft element 3 around the longitudinal axis 21 of the first shaft element 3 is the shift sleeve 2 ' about one through the formation of the swash plate 19 ' predetermined rotational angle of the first switching position of the shift sleeve 2 ' in the second switching position of the shift sleeve 2 ' emotional. During this movement, the first elastic element 13 , the compression spring 13 ' , biased against its elastic force.

By the engagement of the control element 10 , more precisely, the first interventional process 11 of the actuating element 10 , on the swash plate 19 ' experiences the shift sleeve 2 ' an axial movement corresponding to the pitch of the swash plate 19 ' attached profile.

The axial movement of the sliding sleeve 2 ' is due to the geometry of the swash plate 19 ' predetermined and is in the illustrated embodiment by a stop 22 effective shim 22 ' limited.

The spring tongues 15 ' of the holding element 14 stand with the pencil cases 25 of the unlocking element 16 engaged. As a result, the second switching position is locked and an undesirable release of the compression spring 13 ' and a resulting resetting of the shift sleeve 2 ' in the first switching position with no-current actuator 5 prevented.

To release the second switching position of the shift sleeve 2 ' becomes the second coil of the bidirectionally effective electromagnetic actuator 5 energized. 8th shows a detailed view of the connection arrangement 1 with energized second coil of the actuator 5 ,

The actuator 10 learns from the actuator center position 6 a radial, from the longitudinal axis 21 of the first shaft element 3 removing stroke movement in the second actuator position 8th , In the second actuator position 8th of the actuating element 10 comes on the actuator 10 formed in the axial direction, eccentrically arranged second engagement extension 12 in engagement with the unlocking element 16 trained tooth profile 18 ' , The unlocking element 16 becomes due to the engagement of the second engagement extension 12 of the actuating element 10 in the tooth profile 18 of the unlocking element 16 maintained rotationally and can be up to a tooth pitch of the tooth profile 18 ' relative to the shift sleeve 2 ' twisting, resulting in the appropriate design of the angular pitch of the spring pockets 25 and on the pencil cases 25 attached bevels 26 an overpressure of the spring tongues 15 ' of the holding element 14 causes ( 9a . 9b . 11a and 11b ).

To even with stationary, ie non-rotating, first shaft element 3 to be able to trigger the second shift is the unlocking 16 eccentric to the longitudinal axis 21 of the first shaft element 3 arranged. Thus, the unlocking element 16 against the spring force of the spring tongues 15 ' of the holding element 14 be actively twisted, causing the spring tongues 15 ' of the holding element 14 be suppressed and the second switching operation is triggered.
