Description

MOTOR VEHICLE transmission actuator FOR OPERATION OF A MOTOR VEHICLE TRANSMISSION

The invention relates to a motor vehicle transmission apparatus, a motor vehicle transmission actuator for actuating a motor vehicle transmission, an actuating device for a motor vehicle gearbox with a motor vehicle transmission actuator and a motor vehicle drive train with such actuator.

Motor vehicle transmission devices are known in various configurations. Starting from conventional manual transmissions, for example, Automated Manual Transmission (AMT) have been created, in which switching operations controlled electronically (triggered) be. Further, transmission have become known which comprise parallel drive train branches, such as dual clutch transmission (DCT) or parallel shift (PSG).

In automotive transmission devices is often differs between the inner gears with its inner transmission circuit and an external transmission circuit, which - in particular in power-assisted designs or designs with an electric motor - is also referred to as a gear actuator.

The inner gear with its inner transmission circuit in this case has usually the different translations-forming components, such as gears, as well as coupled with these gear wheels and can be coupled components, such as shafts on. In this case, speed clutches or functionally equal or functionally similar means are usually provided by means of which can be generated at the coupling engagement of gears and dissolved to disengagement of gears. This may for example be such that a rotationally fixed connection between a gear of a gear forming the gear set and this gear can be generated supporting shaft or released by means of such clutch. Of these clutches the inner transmission circuit extends up to the interface for external transmission circuit. This usually includes a plurality of mechanisms, each extending from a gear clutch in the direction of the outer transmission circuit. There are known various designs in which the power transmission from the external transmission circuit to the inner transmission circuit, this mentioned mechanisms each comprise a shift jaw or the like that are introduced, for example in a shift rail or shift fork, or the like. The outer transmission circuit has frequently one or more parts, such as selector finger can engage in these Pressing shift jaws on. This is often implemented so that such a shift finger or the like can be moved for selecting a position from which it can then be moved in a further movement differing from the selection movement direction with respect to their usually, for switching.

It is also known that in gear changes in classically styled stepped motor vehicle transmission devices - based on the old gear - run the following three steps in chronological sequence: "disengagement of the old gear" - "Select" - "Loading the target gear". In addition, motor vehicle transmission designs have become known in which choosing or selection movements can take place before the disengagement of the old gear. In such designs, for example, is provided, which is only responsible for the engagement of gears, a main control element or shift finger substantially and additional geometries take over the function of laying out of gears. In particular, so-called secondary control elements for Auslegefunktion be used. Also known is that the additional geometries are on the one hand, for example, at a central gearshift shaft and the other hand to shift mouths, which are provided on the said mechanisms or final output or shift forks or shift rails or the like.

The disengagement geometries act usually in streets where the shift finger or a main control element is not active. It can be provided that a fixed relationship between shift finger or the main actuating element and Auslegegeometrie at the same time represents an active gear lock. Constructive implementations of this approach are therefore referred to as "active interlock".

In such an "active interlock" is intended as a rule that the main control element or the shift finger while in gear in a Mittelbzw. Neutral position can be moved back without an interpretation of the transition. The selection movement is possible in this case before the gear is designed. Examples of such configurations are described for example in DE 102 06 561 A1.

be controlled provided in the arrangements of the aforementioned type gear change operations electronically by means of an electric motor, these designs each have two separate electric motors. One of these electric motors, the so-called. Selector motor, serves to select the gears, and the second electric motor, the so-called. Motor, serves the switching or engagement of gears.

However, addition is known a design principle can be controlled with an electric motor with the gear change operations. In this configuration, which is recognized for example in the introduction of DE 102 06 561 A1, comprises the operating device of the motor vehicle transmission apparatus to a so-called. Shift drum which is rotatably mounted and are introduced into the outer casing slot-like grooves. The inner transmission circuit and final control mechanisms, each having a shift fork is operated in this configuration by means of the shift drum. To this end, engage in the slot-like grooves of the shift forks coupled elements, which slide upon rotation of the shift drum in this slot-like grooves so as to be effected via their coupling with the shift forks and their coupling with gear clutches gear change operations. In this design, the switching sequence of transmission stages or gears by the design of the grooves is set.

By the applicant, a design has been developed which can be called a one-engine-gear actuator, and their rationale will be explained below with reference to FIG. 6. However, since this design is probably internal state of the art, the applicant reserves the right to claim protection for that design. A one-motor gear actuator 200 has precisely an electric motor or the size "IN" in FIG. 6 schematically indicated by the arrow 202. This electric motor 202 is coupled to a Aktormechanik which is indicated schematically in Fig. 6 by the "black box" 204th The electric motor and the motor shaft can be moved or in the two opposite directions of rotation are driven. The one of these two directions of rotation is associated with the "switch" and the other of these two directions of rotation is associated with the "Select". The Aktormechanik ( "black box" 204) performs a function of the respective motor rotation direction switching to the respective output 206 and 208, and decreases according to a kinematic translation change.

And for the fourth nut 24b with the housing 50 is firmly connected or belonging to the housing 50 Nutblech 76 is provided - which is not shown in Figures 4a to 4c.. This Nutbleche 76 may be separately or integrally connected to each other or be integrally formed. This connected to the housing 50 Nutbleche 76 have here in each case a plurality of circumferentially distributed grooves 74th These grooves 74 are open axially to one side, so that the teeth move from the associated Nutblech axially out bzw.72b 72a and can be moved into it. The respective supports Nutblech - when the teeth 72a and 72b positioned therein - the torque of the second 24a and fourth nut 24b (cf. in particular Fig. 4b.). Thereby, the axial driving is ensured, in particular, the axial advancement of the nuts 24a, 24b and by the second gear teeth and a second anti-rotation 70 of the nuts 22a, 22b. These designs of the teeth 72a, 72b and grooves 74 and 76 may be referred to Nutbleche first releasable anti-rotation as the first anti-rotation respectively. It can however also be provided otherwise gestaltetet first (detachable) anti-rotation between the nuts 24a, 24b and the housing 50, which are in particular so that the disengaging gears nuts 24a, 24b are prevented from rotating relative to the housing 50, and to select against rotating the housing or be pivoted.

The nuts 22a, 22b have completed another shift path, while the nuts 24a are left to stand in its axial position 24b. The torque is supported to be of the second anti-rotation or toothing 70 on the toothing or teeth 72a bzw.72b and the Nutenblech 76 (or first anti-twist) on the housing 50th

If the direction of rotation of the motor 54 reversed, the nuts 22a, 22b first move towards each other. These have an axial position as shown in Fig. 4b reaches shown, as are the nuts 24a, 24b meshed again in the spindle toothing and thereby obtain positive locking. Thereafter, the nuts 22a, 22b and 24a move, 24b in synchronism with each other. Slotting them together, as shown in Fig. 4a, the torque is no longer supported on the tooth or the teeth 72a bzw.72b or the first rotation. The nuts 22a, 22b, 24a, 24b and the spindle 16 are rotated as a dressing in a new selector position.

At 72a, 72b, starting einzuspuren the teeth from that of FIG. 4a position as shown in the grooves 74 for the shift operation, it requires a temporary circumferential support of the nuts 24a, 24b to a free-running or it may be advantageous when the nuts 24a, 24b be temporarily supported on a freewheel. To this end, a free wheel 78 is provided in a preferred configuration.

As shown in FIGS. 4a, the nut can be positioned radially 22a within the nut 24 to 4c illustrate, and the nut 22b radially inwardly of the nut 24b. The nut 22 may in particular dive into the nut 24, and the nut 22b may in particular dive into the nut 24b.

An exemplary design for such a free wheel 78 is shown in Fig. 5. The design of FIG. 5 is given in an advantageous manner, in the embodiment according to Figures 3 to 4c. Of the freewheel in accordance with Fig. 5 is formed by a spring plate 80 and a profile 82 as saw-tooth, and comprises a spring plate 80 and a profile 82. The freewheel 78 met in the select direction, the freewheeling condition and Schaitrichtung the lockout condition. In this sense, the shift direction is in particular the direction of rotation of the spindle 16, in this spindle must be rotated to cause the engagement of a gear and the direction of selection in particular the direction of rotation of the spindle 16 in which it is rotated to dial.

In order to determine the selection position of the main 58, 60 and secondary control element 66, it is necessary in the known designs of a one-engine-transmission actuator of an additional rotation angle sensor, wherein the motor control can adjust the angular position for the desired switching position based on the signal of this rotation angle sensor. Such a sensor can be saved according to the embodiment in that z. For example, the formation of the profile 82 is different at the periphery or varied. Thus thunderstorms profile pieces can produce a higher detent force which can be recognized by the engine controller. This gives the possibility of a reference in periodic rotation of the main 58, 60 and secondary control element 66 to sense. The internal engine Inkrementalwegsensor detects the rotational angle position of the main 58, 60 and secondary control element 66. However, it should be noted that - especially as an alternative - for example, a rotation angle sensor can be used.

Further provides the embodiments of the invention the functional surfaces 32b at the end faces of the nuts 24a, 24b, the possibility of designing with a possible occurrence of a "blackout" of the motor control all the gears in the gearbox by a stroke. The functional surfaces 32b has a fixed assignment to the reference to the profile 82 must have or have such a fixed assignment advantageously.

The illustrated embodiment in the design may, for example, for a double clutch transmission (DCT) or a parallel shift (PSG) may be used or be part of a such.

As the exemplary embodiment shown, can be realized for shifting a twin-clutch transmission according to the invention an actuating unit or actuator, which is driven only by an electric motor. The operating unit or entity is characterized - at least in an advantageous design - Compact design with very few parts from. By changing the direction of rotation of the electric motor gears can be both designed and connected as selected new positions. Specifically, the embodiment shows in particular a single-engine transmission actuator for a compact shift rail assembly. In the design with one-motor gear actuator, in particular an active interlock is easily realized or see. So it is - especially in the embodiment - a gear actuator created based on the one-engine-principle with Active Interlock. Further, there is at least according to the embodiment, the possibility of setting a select position in which all the junctions are connected in a holistic "Neutral". LIST OF REFERENCE NUMBERS
