Description

The present invention relates to an ac-

  actuators for actuating a gearbox and a clutch

  vehicle clutch comprising at least one engine

  clutch actuator and at least one action motor-

  gearbox, which drive motors have rotatable output members

  around their respective axes of rotation.

  In modern car manufacturing the under-

  the gearbox and clutch assemblies are most often constructed in such a way that they

  no longer need to be operated manually by a

  conductor, but that a corresponding actuation movement of the conductor is detected by sensors and that orders

  correspondents are then produced in a

  command, orders by which the driver controls on the one hand an actuator used to actuate the clutch and on the other hand

  an actuator for actuating the gearbox

  according to the preset. In the case of ac-

  There is an increasing need, in particular when used in fairly small vehicles, for automatic keepers of this type to keep the space in connection with the entire drive system as small as possible. One very promising way to achieve this is to integrate the entire actuator area for actuating the gearbox and the area into the entire system.

  of the actuator provided for actuation of the clutch

  adorned with each other, and in fact for example where we

  has more space for these different areas.

  The object of the invention is to provide a drive system which, while minimizing the need for space

  allows for a simplified integration of an ac-

  of this type in a drive system.

  According to a first aspect of the present invention, in an actuator system for actuating a gearbox and a clutch of a vehicle, comprising at least one clutch actuation motor and at least one actuation motor of the gearbox, which actuating motors have output members which can

  rotate around their respective axes of rotation, the pro-

  problem is solved in that according to the invention, the axes of ro-

  tation of the output members of at least the two actuating motors are substantially parallel to one another. Thanks to the present invention we then arrive at

  arrange the different sub-assemblies or components of the system

  actuator teme in such a way that they also require

  as little space as possible when assembling them into a system

  global theme of actuators, and at the same time their structure

  ration in a global unit is however possible. If for example the axes of rotation of the different output members

  are thus parallel to each other, this allows to pro-

  yield to the positioning of the various corresponding actuation motors in the same relatively small volume and this

  also allows during the assembly of an action system-

  neur of this type to have a simple structuring of these mo-

  actuators in the actuator system.

  In the case of an arrangement of this type, it is then advantageous to mount substantially parallel

  the axes of rotation of the output devices of all the

  actuators. The space which is then taken up by the sys-

  teme of actuators according to the invention can be in this way

further decreased.

  According to another aspect of the present invention, the problem posed at the start by a system of actuators serving to actuate a gearbox and a clutch of a vehicle, comprising at least one clutch actuating motor and at least one gearbox actuating motor, being in drive connection with a torque transmission member which can pivot around a pivot axis, and at least two of the torque transmission members that can pivot around of this same axis

pivot.

  In this case, provision can be made for the pivot axis

  ment of at least two of the torque transmitting members which can pivot around this pivot axis is substantially parallel to the axis of rotation of a

  output of at least one of the actuating motors.

  The means used to rotate different or-

  torque transmission ganes around a common axis of pi-

  vote, also fulfills the degree of integration or reduced

the overall space used.

  To further reduce the space used in opti-

  at the same time leveraging the transmission of torque, it is

  that at least the two torque transmitting members which

  can pivot around the same pivot axis including

  a gear wheel segment respectively.

  According to a preferred variant configuration, it can be provided in the case of the present invention that only one of the two torque transmitting members which can pivot

  around this same pivot axis is used to actuate the em-

  clutch and another used to activate the gearbox-

  ses, and that the torque transmission member which serves to actuate the clutch is located further away in the direction of the common pivot axis of the actuating motors than the other torque transmission member. A type of

  realization of this type has the advantage that the transmission organ

  torque torque can then be easily coupled

  with other sub-assemblies transmitting the action torque-

  actuation force used for coupling.

  This is how we can foresee, for example, that the

  transmission of the torque used to actuate the em-

  clutch cooperates with a cylinder / master of a formed system

  a master / receiver cylinder used to operate the em-

  clutch. According to another aspect of the present invention, the problem posed at the start by a system of actuators serving to actuate a gearbox and a clutch of a vehicle, comprising at least one clutch actuating motor and at least one gearbox actuator motor, the actuator system being disposed in an actuator housing which is connected or can be connected with a gearbox housing, and the components of the actuator system penetrating the less at times in the gearbox housing in case the gearbox

  actuators is connected with the gearbox housing.

  According to this aspect of the invention, care is therefore taken to

  what a fusion takes place in the space of the action system-

  nors with the gearbox, i.e. the actuator system also uses the space occupied by the gearbox, so that the space that is required

  by the whole system, including the action system-

  nors and the gearbox system, could be

reduced benefit.

  We can then foresee, for example, that the components

  of the actuator system which penetrate at least by mo-

  ment in the gearbox housing include: - an actuator which, depending on the activation of the actuator system, selects at least one group of gears in the gearbox and, from the

  gear group having been selected, can respective-

  ment engage or disengage a speed, or / and - a mechanism with guide track and projection, which upon activation of the actuator system may cause a selection movement or / and an engagement or disengagement movement of the actuator, - at least one torque transmission device, preferably in the form of a toothed wheel segment, which transmits a

  actuation torque by a corresponding ac motor

  clutch or gearbox operation.

  In addition, it is advantageous in the case of the pre-

  invention that the actuator is supported by a shaft arranged so that it can slide in its longitudinal direction in the housing of the actuators and can rotate around its longitudinal axis, and that it engages from the housing actuators in the gearbox housing and can act on different points there

  control elements associated with different speeds or different

  different gear groups. So this means that the organ

  which protrudes out of the action housing-

  nors can directly engage with the different

  control ganes or act on them, without it being

  necessary to have an intermediate control of a tree made

  protruding from the actuator housing or from a shaft projecting from the gearbox housing. This leads to both a reduction in the space required and a simplification of the entire system, since ultimately less

components are required.

  According to another aspect of the present invention,

  it is advantageous to have an electronic circuit of the system

  actuators in or on an actuator housing. This-

  it also helps to increase the degree of integration.

  The present invention is described below more

  in detail from preferred embodiments shown

  shown in the accompanying drawings, in which: - Figure 1 shows a perspective view of an actuator system according to the invention without housing, - Figure 2 shows a perspective view of the actuator system shown in Figure 1 , in the viewing direction II in Figure 1, - Figure 3 shows a perspective view of the actuator system shown in Figure 1 in the viewing direction II in Figure 1, - Figure 4 shows a view in perspective of the actuator system shown in Figure 1 in the viewing direction IV in Figure 1, - Figure 5 shows another perspective view of the system

  actuators according to the invention, which represents the co-

  peration of it with a gearbox,

  - Figure 6 shows a representation of the system of ac-

  actuators according to the invention, which is coupled to a box

and a clutch.

  The figures show a system of ac-

  actuators according to the invention generally designated by the reference 10. This actuator system 10, forming a single construction unit and integrated as such in a drive system, has an actuator zone 12, which is used for the actuation of the clutch, and further has an actuator zone 14, which is used for actuation of the gearbox

  of speeds. We will first describe the action area-

  12 used for actuating the clutch.

  This actuator zone 12 comprises a motor for actuating the clutch 16, the output member of which, that is to say its drive shaft 18, meshes

  with a toothed wheel segment 20. It will be noted that this gear-

  ment is only shown schematically. for example

  the toothed wheel segment 20 present on its outer periphery

  laughing a toothing, which meshes with a toothing on the drive shaft 18. The toothed wheel segment 20 can pivot about a pivot axis Si, which is substantially parallel to the axis of rotation D1 of the output member 18,

  that is to say of the drive shaft 18 of the action motor-

  nement 16. An actuating pusher 24 is coupled in a manner

  lesson in being able to pivot eccentrically with respect to

  the pivot axis S1 with a lever section 22 of the seg-

  the gearwheel 20. By rotating the segment of

  toothed wheel 20 around the pivot axis Si, we cut

  smooth the actuation pusher 24. The actuation pusher

  ment 24 forms for example a piston rod of a master-

  cylinder generally designated by the reference 26 of a mechanism consisting of a master / receiver cylinder which

  can transmit an actuating force from the ac area

  actuators 12 by means of a hydraulic fluid or

pneumatic to a clutch.

  In addition, on the toothed wheel segment 20, eccentrically to the axis of rotation S1i engages a compensating force device 28 which bears at the other end on an actuator casing 30 that the 'can be seen in Figures 5 and 6. This compensating force device 28 with its compensating spring 32 is arranged in such a way that it prestresses when performing a recoil movement the toothed wheel segment

  in the same direction of pivoting around the pivot axis

  S1, that the direction of drive by the actuating motor

  ment 16. In the optimal case the force supplied by the compensating spring 32 is as great as the force opposed to the zone of the actuators 12 by an energy accumulator of the clutch during the disengaging movement, such

  so that the actuating motor 16 does not need to

  ter that the inertial force or the frictional forces, while the actuating motor 16 does not need to operate against the force of the clutch energy accumulator. When the clutch position is reached or after that, the compensating force device 28 crosses a neutral position of maximum compression, and maintains

  then in this way an actuating position which corresponds

  lays in the disengaged position of the clutch.

  It can be seen in FIG. 6 that the master cylinder 26 leaves part of the actuator housing 30 and arrives almost directly up to a housing 34 containing the clutch, so that the path of the fluid line between the master- cylinder 26 and a not shown receiving cylinder of

  the clutch is kept as short as possible.

  The actuation zone 14 of the gearbox comprises two actuation motors 36, 38. In this case, the actuation motor 36 serves as a preselection motor, with which the type of movement of a member can be predefined.

  actuator 40 formed in the form of a finger

  in a manner which will be described further below. The mo-

  actuator 38 then serves to effectively

  movement of the actuator 40.

  The actuator 40 is, as can be seen

  in particular in Figure 2, integral with a guide element

  dage 42 or is formed integrally therewith.

  The guide element 42 is fixed on a shaft part 44,

  which shaft part 44 is housed completely inside

  laughter of the actuator housing 30 in such a way that it can slide in its longitudinal direction and that it can rotate around its longitudinal axis L. For this purpose the shaft part 44 can for example be mounted in its two

  end zones in corresponding bearings on the car-

  ter 30 of the actuators so that they can slide and be

see turn.

  A second toothed wheel segment 46 which can also be seen in FIG. 1, and which is pivotally mounted around the axis S1 also like the toothed wheel segment

  that we have already described previously, meshes with the mo-

  actuator 38. Here also the drive shaft 48

  of the actuating motor 38 may again have a dent-

  ture, which meshes with a corresponding toothing on the outer peripheral zone of the gear wheel segment 46. It can be seen above all in FIG. 2 that the gear wheel segment 46 is in the direction of the pivot axis S1 closer to the actuating motors 16, 36, 38 as the wheel segment

  toothed 20. This shows the advantageous aspect according to-

  which the gear wheel segment 20 can be coupled in a simple way, to actuate the clutch, with the others

  groups of the actuator area 12 which require relative

  a lot of space, namely on the side opposite the

  toothed wheel segment 46. The toothed wheel segment 16 pre-

  feels a hinge projection 50, fixed on its opposite side

  dried on the toothed wheel segment 20. A corresponding articulation projection 52 is provided on the guide element 42 or is coupled with the latter. These two articulation projections 50, 52 are coupled to each other by an articulated rod

  54, the articulated rod 54 having cups of articulation

  respective 56, 58 in the coupling area for the respective coupling projections 50 and 52. It is established

  in this way a double ball joint link in-

  be the toothed wheel segment 46 and the guide element 42.

  The articulated rod 54 is designed to be mounted in a po-

  distorted position with respect to the shaft part 44. A pivot

  gearwheel segment 46 around the axis of

  pivoting S1 induced by the excitation of the actuating motor

  ment 38 leads to a peripheral movement of the projection

  hinge 50 about this pivot axis S1. This soft-

  is transmitted to the articulated rod 54 and is transmitted

  by the latter to the guide element 42. Like the articulated rod

  lée 54 is mounted in a warped manner relative to the shaft part 44, in this case on the one hand is transmitted to the articulation projection 52 a force component, which is oriented in the longitudinal direction of the part tree 44, and we

  on the other hand transmits a force component, which is tan-

  gential to a circle of envelopment around the long axis

  tudinal L. This means that by this actuating force the shaft part 44 can move in its longitudinal direction as well as around its longitudinal axis L. The guide element 42 has on its surface which is far from the shaft portion 44 a guide track 62 which can be recognized in FIG. 3. This guide track 62 has two track sections 64, 66 which extend roughly in the peripheral direction around the shaft part 44, track sections 64, 66 which are connected

  to each other at one of their peripheral end zones

  ques by a section of track 68 extending in the direction lon-

  gitudinal L of the shaft part 44, and which are connected to each other in their other peripheral end zone

  by a curved track section 70. In this guideway

  dage 62 a guide element 72 engages with its sec-

  track 64, 66, 68, guide element 72 which may for example be formed by a screw, which is screwed into a support for guide element 74 and projects above it in the guide track 62. The guide element support 74 is constituted for example in the form of a U-shaped stirrup, which can pivot freely on its two branches relative to the shaft part 44 and which is mounted so axially movable. In this case, the device is produced in such a way that the guide element support 74 can also pivot freely relative to the housing of the actuators.

  , but cannot move in the long direction

  gitudinal of the shaft part 44. A branch 76 of the guide element support 74 is integrally connected with a transmission element 78, constituted for example in the form of a toothed wheel or a wheel segment toothed. This transmission element 78 meshes with another element of

  toothed wheel 80, which in turn meshes with a drive shaft

  drag 82 of the actuating motor 36. For this, the

  gear wheel 80 may for example have in its peripheral zone cooperating with the transmission element 78 a front toothing. We obtain by means of cogwheels

  78, 80 and from the drive shaft 82 a transmission mechanism

  self-locking mission so that then, when the actuating motor 36 is not energized, the guide element support 74 is held in its pivoting position and that in this way the guide element 72 coming in taken in the guideway 62 is also maintained in its position. It will then be assumed, for example, that the guide element 72 engages in the guide track 62 of a

  in such a way that it is positioned on the passage area

  be track section 64 and track section 68. When the

  actuation motor 36 is maintained, it is then possible to transmit

  be by adequate excitation of the actuating motor 38

  an actuating force by the control rod 54 to the elec-

  guide ment 42 in such a way that this guide element 42, being necessarily guided by the guide element 72, moves at the same time as the shaft part 44 in the direction of the longitudinal axis L of the part of tree 44,

  the guide element 72 then moving along the sec-

  tion of track 68. A pure sliding movement of the shaft part 44 is therefore produced in this way.

  direction of its longitudinal axis L, with a sliding movement

  correspondingly of the actuating member 40. This movement

  the sliding element of the actuating member 40 is then transmitted to one of the control dogs 86, 88, 90 of the gearbox in such a way that one of these dogs respectively 86, 88 or 90 is moved and that in this case a synchronization device 94, 96, 98, provided in the gearbox and associated beforehand with the respective dogs 86, 88, 90, is actuated to engage or disengage a

speed.

  A movement is obtained to select one of the respective control dogs 86, 88, 90 in cooperation with the actuator 40 by causing a movement of

  rotation of the shaft part 44 around its longitudinal axis

  dinal L. One can put for this purpose for example the guide element 72 again in a passage zone between one of the track sections 64, 66 and the track section 68, then the actuating motor 38 can be briefly excited, so that the guide element 72 is positioned in the track section 68 and then the actuating motor

  36 is excited, so that the guideway element

  42 and in this way also the shaft portion 44 pivot about the longitudinal axis L by virtue of the pivoting then obtained from the support 74 of the guide element. In this way, the actuating member 40 is brought into alignment with one of the other control dogs 86, 88, 90, in order to be able to actuate one of the other synchronization devices 94,

  96, 98 of the gearbox 92 to switch on or off

  trigger a speed stage. If a pivoting movement and a sliding movement of the actuating member 40 are to be obtained at the same time, the guide element 72 is then positioned in an area of the guide track 62, in which one of the sections track 64, 66 is in connection with the curved track section 70. A subsequent excitation of the actuating motor 38 leads first to a short sliding movement, then to a pivoting movement and then again to a movement sliding of the shaft part 44 and a corresponding movement of the member

actuation 40.

  As described above, we can provo-

  quer by appropriate control of the two drive motors

  ment 36, 38 in this way a movement of the actuating member 40, by which it can be moved also

  well to select respectively a group of two vi-

  braids, that is to say one of the control dogs 86, 88, 90 associated, as also to slide the control dogs 86, 88, 90 and consequently cause the activation or deactivation of a synchronization device 94,

  96, 98 of one of the selected gearboxes

  tesses 92. It should be noted that the mounting and the mode of operation

  ment of an actuator zone of this type for actuating a

  gearbox is described in detail in the de-

  German patent application 199 16 169 of the applicant of the present application. We expressly refer here to this de-

  German patent application, in particular with regard to the disclosure concerning the construction or the mode of operation

  actuation of an actuator zone of this type and

  will collect the content of this disclosure as the content of

  the disclosure of this application.

  As can be seen from the different representations, the actuator system according to the present

  present invention with respect to the arrangement in the es

  pace of the different components of it some particu-

  specificities, which have the consequence that a global system of actuators 10 is obtained, which on the one hand can form a single module, and which on the other hand however requires very little space. A first essential aspect for this is that all existing drive motors

  16, 36, 38 are positioned in such a way that their ar-

  drive belts 18, 82, 48 can rotate around axes

  which are substantially parallel to each other

  very. By the expression "substantially parallel" is meant here that there may also be slight deviations from an exactly parallel orientation, due for example to

  machining or mounting tolerances. This parallel positioning-

  the axis of all the axes of rotation of the different drive shafts

  dragging 18, 82, 48 has the consequence that all the drive motors 16, 36, 38 can be made when they are integrated into the system in the same direction, that is to say can be inserted into the casing 30 In addition it allows

  to have a very narrow positioning in the space of different

  different drive motors 16, 36, 38 relative to each other

to others.

  Another essential aspect is that we can do

  pivot the two toothed wheel segments 20, 46 serving as a

  torque transmission ganes around the common axis of pi-

  If vote (see Figure 1). This also makes it possible to have a very small space requirement, because ultimately the

  two drive motors 16, 36 do not require significant

  significantly more space with the toothed wheel segments 20,

  46 associated that one of these two motors 16, 38 with the seg-

  cog wheel 20 or 46 alone, associated with it.

  The two toothed wheel segments 20, 46 are arranged in a staggered fashion in the direction of the pivot axis Si, the gear wheel segment 20 serving to actuate the clutch is

* finding further away from the drive motors 16, 38.

  In this way, the space available between the toothed wheel segment 46 and the part of the shaft 44 can be used for

  position the articulated rod 54, while one can position on the side of the toothed wheel segment 20, being

  opposite the actuating motors 16, 38, the others include

  components used to operate the clutch, in particular

  link the compensating force device 28 with its

  compensation spring 32 as well as pusher 24 and cy-

sensor liner 26.

  Another essential aspect of the present invention

  tion is that the actuator 40 of the action system-

  10, designed to cooperate with different control dogs 86, 88, 90 of the gearbox 92, is provided on a part 44 of the shaft supported inside the housing of the actuators 30 and which even comes out of the housing of the actuators 30 to cooperate with the control dogs 86, 88, 90 of the gearbox 92. There is therefore no intermediate shaft part, which for example would be coupled to the shaft part 44 and would enter the case of the box

  of speeds and would support at this place the organ of action-

40.

  Another essential aspect of the present invention

  tion is that, as can be seen in particular at the fi-

  gure 5, different components or sub-assemblies of the actuator system 10 exit from the actuator housing 30 and

  engage inside the gearbox housing

  braids 100. On the one hand, as has already been described, the actuating member 40. In addition, it can be seen in the figure that the support of the guide element 74 and at least one part of the guide element 42 also leave the casing of the actuators 30 or are outside of it. We

  see for example that one can foresee on the housing ac-

  stanchions 30 in the two end zones of the part

  shaft 44 a corresponding shaft support 102, which makes

  I also protrude from the housing of the actuators 30 and sup-

  carries in its projecting area then a terminal area of the shaft portion 44 so that it can rotate and

  slide in the longitudinal direction L. We therefore use the es

  space available in the gearbox housing 100 in addition for components of the actuator system, so that the space required at the top of a unit stressed from the gearbox can be further reduced and the actuator system 10. It will further be noted that the toothed wheel segments 20, 46 can also protrude at least in a few rotational positions out of the housing 10 of actuators 30 and then engage locally in the

  gearbox housing 100.

  It is also possible to mount the actuator system according to the invention in such a way that there is available on or in the actuator housing 30 a space in which the electronic control circuit for the various components is then placed. actuating motors 16, 36, 38. By means of the respective connection contacts 104, 106, 108 the motors

  16, 36 and 38 can then be connected to this electrical circuit

  control board. This also contributes to a better integration of the system, because ultimately it only remains to put an electrical connection of this electronic circuit of

  control on the electrical system of a vehicle.

  It will also be noted that the actuator housing is placed by its connection side or its connection face 110 on a surface of the housing of the gearbox 100 located opposite, by interposing a sealing device, for example a ring sealing or the like and that in this way the gearbox housing 100 and the actuator housing 30 together form a closed fluid-tight space. The various moving components of the actuator system 10 can then be lubricated by

  using the transmission oil at the same time.

  As the actuating motors 16, 36 and 38 come uni-

  only engaged by their drive shafts or by these

  mounting areas also closed in a leak-tight manner

  in the housing of the actuators 30, as can be seen in FIG. 5, there is no risk here that the actuating motors 16, 36, 38 are damaged due to the
