Definitions
- the present invention relates to a monorail switching device for a multi-speed manual transmission according to the preamble of claim 1 and a transmission according to claim 10.
- the switching movement of the shift rail in the axial direction is transmitted via an axially fixedly connected to the shift rail shift finger on a selected Heidelberggabelarm and further on an associated shift rocker or shift fork.
- the shift rockers or shift forks engage in sliding sleeves, which in turn are displaceable for switching the gears between a non-switched neutral position and at least one switching position. In the switching position, the drive torque is transmitted via one of the respective sliding sleeve associated gear set.
- the kinematic decoupling of the selection movement from the switching movement advantageously causes the force required to select the shift gate to be significantly reduced, thus allowing the use of an electromagnetic or electrodynamic selection actuator with smaller dimensions and faster response than, for example, a pneumatic actuator. Smaller dimensions of the selector actuator in turn allow a flexible arrangement of the construction parts on or in the gearbox. Suitable embodiments of an electromagnetic or electrodynamic Wählaktuators are for example in the

- the locking forces on the two Rastierhülsen are the same size and directed in opposite directions, so that they cancel out in total and no resulting force on the shift rail, which could affect the switching or dialing.
- the prestressed Rastierelement is arranged on the selector element and in at least one latching recess can be latched, which is provided in the switching element.
- the selection element preferably has a bush-shaped basic body and is arranged concentrically with the bushing or annular switching element. In this way, the switching and the selection element can be arranged, for example, as two bushings with different diameters concentric with each other and into each other, whereby the required space is further reduced.

- the selection element has a locking element which is rigidly arranged on the selection element, by means of which the respective unselected shift fork arms can be locked in a switching position.
- a locking element is arranged such that it protrudes in each selection position of the selector in each case in the driving grooves of the non-selected selector fork arms.
- these shift fork arms are blocked in their freedom of movement in the axial direction and it is ensured that only one shift fork can be operated in each selection position.

- the shift finger 4 embodied in one piece with the shifting element 3 protrudes in the radial direction through the longitudinal opening 25 in the selection element 5 and is in the axial direction along the longitudinal opening 25 displaceable.
- the shift finger 4 is designed so broad that it rests on both sides of the inner surfaces of the longitudinal opening 25, so that there is a virtually play-free, positive connection in the direction of rotation and that the switching element 3 at a rotation of the selection element 5 of the shift finger 4 by the same angular amount is turned.
- each shift forks 26, 27 and 28 has a Heidelberggabelarm 6, 7, and 8, which is rigidly connected at one end to the associated shift fork and in the region of the other end has a driving groove 29, in which the switching element 3 with its shift finger 4th protrudes at appropriate dialing position.
- the selector element 5 has an integrally formed with the selector element 5 approach 14.
- the projection 14 projects in the installed state in a recess 15 in the transmission housing 10, so that the selection element 5 is held fixed to the housing in the axial direction, but can rotate about the central axis 1 1.
- the recess 15 is formed, for example, as an arcuate groove with a rectangular cross-section in the transmission housing 10, wherein the groove extends in the direction of rotation of the projection 14.
- the axial guidance of the selection element 5 is effected by a pin. This sits firmly in a hole in the housing and protrudes into a slot in the selector element 5 inside. This slot extends perpendicular to the axis of rotation in the circumferential direction in order to allow a rotation of the selector element 5 about the central axis 1 1.

- In the through hole 19 is the helical compression spring 20, at both ends of which a Rastierhülse 21 and 22 is arranged as Rastierelement.
- the Rastierhülsen 21 and 22 have such a large outer diameter that they are securely guided in the through hole 1 9, but are easily displaced, e.g. by the force of the helical compression spring 20.
- the selection movement is triggered by a Wählaktuator 13 which acts rigidly on a selector finger 12 and so the selector element together with the switching element 3 about the common central axis 1 1 is rotated.
- a locking member 9 for locking the unselected shift fork arms 6, 7 and 8, respectively, is shown in FIG. Adjacent to the longitudinal opening 25 through which the shift finger 4 protrudes into the driving groove 29 of the respective selected Wegmülarmes 6, 7 and 8, the locking element 9 is rigidly mounted on the selector element 5. In this example, the locking element 9 is made in one piece with the selection element 5.

- the shift finger 4, in conjunction with the longitudinal opening 25 again forms a positive connection for transmitting the selection movement from the selector element 5 to the switching element 4, whereby the selector element 5 performs each rotational movement to select the shift gate together with the switching element 3.
- the selection movement is triggered here by a Wählaktuator 13, which engages a rigidly arranged on the selector element 5 selection finger 12 and so the selector element 5 together with the switching element 3 about the common center axis 1 1 is rotated.
- this embodiment as shown in Fig. 5, a rigidly arranged on the selector element 5 locking element 9, which engages in the driving grooves of the unselected shift fork arms 6, 7 and 8 and this fixed to the housing, so that in an axial switching movement the shift rail 2 only the respectively selected shift fork 6, 7 or 8 moves with the shift rail 2.
- the Heidelberg einsrastêt für 87 is executed contrary to the Heidelberg einsrast réelle in the first embodiment so that a resiliently biased Rastierelement 21 on the selection element 5 angeord- net and in a latching recess 1 6 can be latched, which is arranged in the switching element 3.
- the Rastierelement 21 is pressed by a helical compression spring 23 in the locking recess 16, wherein the helical compression spring 23 is biased by a locking screw 24.

- the locking recesses can also have different depths and shapes, such as, for example, rounded flanks.
- the function of the monorail switching device 1 is essentially the same in both described embodiments.
- the selection element 5 and the switching element 3 are first rotated by the Wählaktuator 13 until the shift finger 4 is in the desired driving groove 29 of the selectable Weglarmes 6, 7 or 8. This selects the desired shift gate. Since the Heidelberg einsrast réelle 18 is disposed between the switching element 3 and the selector element 5 and the switching element 3 rotates together with the selector, which remains necessary for selecting the shift gate force remains relatively low and completely unaffected by the Heidelberg einsrast réelle 18th
- the shift rail 2 is displaced in the axial direction of the shift actuator, not shown.

- the locking force of Heidelberg einsrast réelle 18 is overcome.
- the neutral position is initially approached by the shift actuator, then the selection actuator selects the desired shift gate before the shift actuator then switches to the desired target gear.
- switching position latches are conceivable which latch a neutral position and / or one or more switching positions.
- the individual features of the described embodiments can be combined.
- the switching element in the first embodiment for example, also be designed bush-shaped, and conversely, the switching element in the second embodiment are designed as a switching ring.
