The first case 100 is non-rotatable and axially displaceable on a shaft 180 stored at your in 2 right end via a gear transmission with a first adjustment actuator in the form of an electric motor 185 and a cam gear for engaging the first clutch 4th is coupled, the one cam 190 for actuating a plunger of a hydraulic cylinder 195 has (cf. 4th ).

The second sleeve 200 is non-rotatable and axially displaceable on one to the shaft 180 concentric shaft 280 (see. 6th ) stored at their in 2 right end via a gear train with a second adjustment actuator in the form of an electric motor 285 and a cam gear for engaging the second clutch 5 is coupled, the one cam 290 for actuating a plunger of a hydraulic cylinder 295 having.

The first and second pods 100 , 200 are in the 2-6 each shown unwound.

As can be seen from this, the first sleeve 100 a first backdrop with an in 2 hatched actuation section 111 , a first adjustment section 112 (see. 3 ), a neutral section 113 (see. 4th ), a second adjustment section 114 (see. 3 ) and an actuation section indicated by hatching 115 (see. 4th ) on. The neutral section 113 is with an idle section 116 (see. 5 ) connected. In this first backdrop is a pen 12th the first sliding sleeve 10 the first double synchronization device out (cf. 2 ).

The first case 100 has a second backdrop with an in 2 hatched actuation section 121 , an adjustment section 122 and a neutral section 123 on that to the in 2 right face of the first sleeve 100 is open so that a pin 32 the third sliding sleeve 30th the third double synchronizing device can move into this further setting and then guided through it or (again) move out of it (cf. 5 ).

The first case 100 shows two more scenes 131 , 132 on, taking into the wider backdrop 131 a spring-loaded linear actuator 300 engages and a pin attached to the gear case 133 in one of the two other scenes 131 , 132 is guided and can go from one to the other.

The second sleeve has an analogous manner 200 a first backdrop with an in 2 hatched actuation section 211 , a first adjustment section 212 , a neutral section 213 , a second adjustment section 214 and an actuation section indicated by hatching 215 on. The neutral section 213 is with an idle section 216 connected. There's a pen in the backdrop 22nd the second sliding sleeve 20th the second double synchronizer out.

The second sleeve 200 has a second backdrop with an in 2 hatched actuation section 221 , an adjustment section 222 and a neutral section 223 on that to the in 2 left face of the second sleeve 200 is open so the pin 32 the third sliding sleeve 30th the third double synchronization device can move into this further setting and then guided through it or (again) move out of it (cf. 3 ).

The second sleeve 200 shows two more scenes 231 , 232 on, taking into the wider backdrop 231 the linear actuator 300 engages and a pin attached to the gear case 233 in one of the two other scenes 231 , 232 is guided and can go from one to the other.

The electric motor turns to shift into first gear ① 185 the first case 100 in your in 2 shown first axial position from its in 2 shown (angular) position, as in 2 indicated by a movement arrow.

This causes the pen to move 12th initially from the neutral section 113 in the first adjustment section 112 , as from the sequence of figures 2 → 3 recognizable. This moves the first sliding sleeve 10 to the left in 1 , 2 so that in 1 left gear with the shaft 3 is rotatably connected.

If you turn it further, the pin moves 12th from the first adjustment section 112 in the operating section 111 , as from the sequence of figures 3 → 4th recognizable. In this rotary position, the cam operates 190 the plunger of the hydraulic cylinder 195 and thereby closes the first clutch 4th .

Rotation in the opposite direction first actuates the hydraulic cylinder 195 finished so that the first clutch 4th opens ("normally open clutch"). Then the first gear is disengaged. By continuing to turn, third gear ③ can be engaged and then the first clutch 4th closed or then the first clutch by turning in the opposite direction 4th opened and the third gear disengaged.

In an analogous manner, by turning the second sleeve in opposite directions 200 by the electric motor 285 in your in 2 shown first axial position from its in 2 The disengagement (angle) position shown can alternatively be switched to fourth or sixth gear.

The first and second sleeves are used to shift into fifth gear ⑤ 100 , 200 in your in 2 , 3 rotated angular positions shown. The pin, which is fixed to the gearbox housing, is placed in this 233 the second sleeve 200 axially fixed, while the first sleeve 100 is axially displaceable.

Now the linear actuator pulls 300 the first and second sleeves 100 , 200 axially towards one another or towards one another. This will make the first pod 100 axially from its first axial position ( 2 ) to the second, axially through the pin fixed to the transmission housing 233 laid down, sleeve 200 towards its second axial position ( 5 ) drawn as in 2 indicated by a movement arrow.

This drives like from the sequence of figures 2 → 5 recognizable, the pen 32 the third sliding sleeve 30th the third double synchronizer in the neutral section 123 a and becomes with a subsequent rotation of the first sleeve 100 then passed through this.

The electric motor 185 now turns the first case 100 , as in 5 indicated by a movement arrow.

As already explained above with reference to the first gear, this causes the pin to move 32 initially from the neutral section 123 in the adjustment section 122 . This moves the third sliding sleeve 30th to the left in 1 , 5 so that the gear that is in 1 the third from the left is with the wave 3 is rotatably connected. If you turn it further, the pin moves 32 from the adjustment section 122 in the operating section 121 . In this rotary position, the cam operates 190 the plunger of the hydraulic cylinder 195 and thereby closes the first clutch 4th .

During this rotation, it becomes the pen 12th the first sliding sleeve 10 the first dual synchronizer in the idle section 116 guided.

Reversing this sequence creates the first clutch 4th reopened, the fifth gear disengaged and when the linear actuator is deactivated 300 the first sleeve due to the spring preload 100 from their second position ( 5 ) back to their first position ( 2 ) pushed back.

The first and second sleeves are used to shift into second gear ② 100 , 200 in your in 6th rotated angular positions shown. Conversely, the pin, which is fixed to the gearbox housing, is located in this 133 the first case 100 axially fixed, while the second sleeve 200 is axially displaceable.

Now pulls the linear actuator 300 the first and second sleeves 100 , 200 axially towards one another or towards one another, the second sleeve 200 axially from its first axial position ( 2 ) to the, axially through the pin fixed to the gearbox housing 133 fixed, first sleeve 100 towards its second axial position ( 6th ) drawn.

This drives like from the sequence of figures 2 → 6th recognizable, the pen 32 the third sliding sleeve 30th the third double synchronizer in the neutral section 223 a and becomes with a subsequent rotation of the second sleeve 200 then passed through this.

As explained above, this allows the pen 32 the third sliding sleeve 30th to the right in 1 , 6th move so that the gear that is in 1 the third from the right is, with the wave 3 Is rotatably connected, and when turning the cam 290 the plunger of the hydraulic cylinder 295 actuated and thereby the second clutch 5 close ("normally open clutch").

In an analogous manner, it is also possible to switch to reverse gear, as indicated by a dashed link on the first sleeve 100 indicated. As described above, this can be used to move a pin for moving a shift fork to engage reverse gear (not shown).

2 thus shows a disengagement angular position of the first adjusting element and second adjusting element in their first axial positions, 3 turning into a first angular insertion position of the first adjusting element in its first axial position, 4th an actuating angular position of the first adjusting element in its first axial position, 5 a disengagement angular position of the first adjusting element in its second axial position and 6th a disengagement angular position of the second adjusting element in its second axial position.
