Commanding apparatus 1 has motor 2, the rotor that described motor is had stator and can be driven by stator.Being configured in this and not illustrating further for clearly reason of motor 2.The rotor anti-rotating ground of motor 2 is connected with leading screw 3 (also can be referred to as screw rod or worm screw).First gear 4 engages with the outer threaded portions section 16 of leading screw 3, and described first gear has the first diameter/first segment circular diameter, and described first diameter/first segment circular diameter circumferentially remains unchanged substantially.Therefore first gear 4 is configured to be circular.Second gear 5 and the first gear 4 be coaxial to be arranged and anti-rotating ground is connected with the first gear 4.First gear 4 and the second gear 5 are preferably connected to each other/are configured to integral with one another on material.Or one or two gears 4 and 5 in two gears be implemented as sintered part or by strengthen, such as fiber strengthened plastics make.The design proposal of described material aspect depends on the friction pair of expectation.
Second gear 5 engages with tooth bar 6 again, and diameter (the Second bobbin diameter)/second section circular diameter of described second gear is configured to the first diameter being significantly less than the first gear 4.Second section circular diameter is also configured to circumferentially substantially remain unchanged.Therefore second gear 5 also constructs conglobate.Except joint diameter of a circle except, the first gear 4 and/or the second gear 5 top circle be also configured to circumferentially remain unchanged with tooth root diameter of a circle.Tooth bar 6 in its axial direction (that is along its longitudinal axis) is installed movably.The rotational motion of the rotor of motor 2 causes the rotation of leading screw 3 by this layout and finally causes the motion/maneuvering motion of the axis of tooth bar 6.Leading screw 3, first gear 4, second gear 5 and tooth bar 6 are helical teeth.
The longitudinal axis that its longitudinal axis is substantially perpendicular to the first gear 4 is arranged to by leading screw 3, first gear 4 is arranged with the midplane of its middle plane parallel in the second gear 5 based on the coaxial setting relative to the second gear 5, and tooth bar 6 is oriented its longitudinal axis again perpendicular to the longitudinal axis of the first and second gears 4,5.
In order to determine rotor so that the pivotal position/rotary state of leading screw 3, motor 2 is included in this rotor-position sensor be not shown specifically, and described rotor-position sensor is such as arranged relative to rotor coaxial.
See in fig. 2 so, commanding apparatus 1 also has housing 7.Described housing 7 one aspect holds motor/fixing described motor, and for the other engaged element of supported/guided, i.e. leading screw 3, first and second gear 4,5 and tooth bar.
External enwergy like this is seen, motor 2 itself has housing equally, hereinafter also referred to as being motor casing 8.Described motor casing 8 is configured to be cylindricality substantially as also seen very well from Fig. 3 and 4.Subsequently at cylinder hereinafter also referred to as two bottom sections for the first and second end faces 9,14 being arranged other component.In the hole of introducing through-hole form in running state on the first end face 9 of leading screw 3 of motor 8.By described hole, leading screw 3 to extend in the inside of motor casing 8 and in inside with rotor anti-rotating (material fit ground, power ordinatedly or form fit ground) be connected.With motor casing 8 with the first end face 9 opposite ground the second end face 14 be adjacent to, at motor casing 8 outer installment electronic unit 10.Electronic unit 10 controls motor 2 and supplies described motor for driving with electric energy.Electronic unit 10 also has plug accommodating part 15, and the longitudinal axis that described plug accommodating part is parallel to leading screw 3 is directed.
Leading screw 3 is bearing on two regions in radial directions.The supporting of described radial direction realizes relative to housing 7.On conglobate towards the structure of motor 2 (not having teeth portion) end regions, leading screw is bearing in the hole of the first end face 9 in radial directions, wherein motor casing 8 again fixing (being such as pressed into) in the housing 7 of commanding apparatus 1.On the same structure that deviates from motor 2 conglobate (not having teeth portion) end regions, leading screw 3 is rotatably supported in the housing 7 of commanding apparatus 1 in receiving opening.The outer threaded portions section 16 of leading screw 3 extends between these two end regions, and it is self-locking that described outer threaded portions section is implemented as in this embodiment.But to this as an alternative, the gradient of the outer threaded portions section 16 of leading screw 3 also can be self-activating.
Leading screw 3 to join in the external screw-thread of the first gear 4 by its external screw-thread/that is engages with it.Therefore, the rotation of leading screw 3 causes the rotation of the first gear 4.Because the second gear 5 coaxially and anti-rotating ground be connected with the first gear 4, so described second gear moves along identical sense of rotation when the first gear 4 rotates together with the first gear 4.Little in order to structure space is held in, select the high velocity ratio of two gears 4,5.The external screw-thread of the second gear 5 engages with the teeth portion on tooth bar 6 again.Bolt 17 the first gear 4 and the second gear 5 the sidepiece deviated from each other respectively on outstanding, described bolt again radial support in the accommodating part of housing 7.
Tooth bar 6 supports as has been shown in the axial direction movably.In order to guide tooth bar 6 when mobile operating, in housing 7, being provided with guidance field 11, although described guidance field allows the axial motion of tooth bar 6, but stoping the relative movement transverse to described axial direction.The pressure chamber 12 of hydraulic pressure is adjacent to the end face pointed to along steering of tooth bar 6, and described pressure chamber 12 is loaded pressure according to the position of tooth bar 6.In this region of end face, tooth bar 6 is implemented as piston and then forms the piston of active cylinder.So, be axially adjacent to described piston area, the side deviating from pressure chamber 12 arranges the teeth portion of tooth bar 6.Pressure chamber 12 continue via connecting pipeline 13 and the hydraulic pressure of the clutch side do not illustrated further at this accommodating part, be such as connected with slave cylinder.So, slave cylinder is originally connected with the release bearing of clutch again in clutch actuator when, and described release bearing acts on the pressing plate of clutch in the mode of movement.Commanding apparatus 1 is implemented as clutch actuator and is preferably implemented as hydraulic coupling final controlling element (HCA).As in the design proposal of braking system, connecting pipeline 13 again directly with brake slave cylinder and be connected, to make brake shoe move.Alternative is in the clutch operating system of hydraulic pressure, and clutch control also can pneumatically, such as carry out by means of air.
In addition, housing 7 preferably has reference stop in the scope of guidance field 11, and described reference stop does not illustrate further at this.Reference stop is arranged to, make tooth bar 6 by stopper area, such as by the convex shoulder in circumference in the axial direction backstop in mobile final position.Described mobile final position can tooth bar 6 shift out completely or realize under the state that moves into completely.The state (the first final mobile position) moved into completely realizes in the following cases: tooth bar 6 is observed in fig. 2 and is moved into left as far as possible in pressure chamber 12 and therefore uses pressure-loaded pressure chamber 12 large as far as possible.At this, tooth bar 6 backstop in reference stop.The state (the second final mobile position) shifted out completely realizes in the following cases: tooth bar 6 is observed in fig. 2 and shifted out from pressure chamber 12 to the right as far as possible and therefore use pressure-loaded pressure chamber 12 little as far as possible.Specific relevant to the rotation angle pivotal position of the rotor of motor 2 and tooth bar 6 so that each position moving axially displacement along it between final mobile position of piston be associated.Therefore, tooth bar forms a part for the active cylinder of commanding apparatus 1.
Two commanding apparatuss 1 are also shown in figure 3, and described two commanding apparatuss are combined into element of construction.The commanding apparatus 1 of the commanding apparatus system of such realization is arranged side by side into, and makes it motor 2 is substantially parallel to be arranged side by side, and wherein its first end face 9 points to identical direction.Arrange to the substantially parallel stretching, extension of leading screw 3 be connected with the rotor of motor 2.Two tooth bars 6 of commanding apparatus 1 also stretch substantially in parallel with each other.This commanding apparatus system 1 such as can be used in handling double clutch, and wherein each commanding apparatus 1 acts on the release bearing of the sub-clutch of double clutch in the mode of adjustment.
To the location of commanding apparatus 1 as an alternative, the commanding apparatus 1 of commanding apparatus system is also oriented as shown in Figure 4, and the motor 2 of commanding apparatus 1 is oppositely arranged each other.Commanding apparatus 1 is arranged in this case, makes the leading screw 3 that is connected with motor 2 each other oppositely but also stretch in parallel with each other all the time.First end face 9 of leading screw 3 therefore toward each other and refer to respectively in the opposite direction.The tooth bar 6 of two commanding apparatuss 1 so stretches equally side by side in parallel with each other.
In addition, one or two gear 4,5 in two (first and second) gears 4,5 also may substitute all gear and be configured to operative gear, the teeth portion of described operative gear does not have complete in whole circumference structure, but only around portion's section structure of circumference.Such as, the teeth portion of gear 4,5 circumferentially can extend with the angle of 90 ° to 270 °.Thus, gear 4,5 can be configured to part dish (such as half dish) respectively.Teeth portion portion section is so arranged again with one heart with its run-on point, but relative to each other such as arranges rotationally with 180 °, and therefore the corresponding teeth portion of described teeth portion portion section and leading screw 3 or tooth bar 6 engage.
In other words, therefore, implement commanding apparatus 1, wherein motor force is delivered on worm driving device (screw drive device/lead screw transmission device).Having, large diameter worm gear (the first gear 4) is upper settles obviously less gear (the second gear 5), described second gear driving rack 6, via described rack linear ground mobile piston (such as, active cylinder piston) to produce pressure.Therefore, multiple type of driver is accessed in systems in which.First, moment is fricton-tightly delivered on worm gear (the first gear 4), to be fricton-tightly delivered to all the time subsequently on the second gear 5 and to be finally fricton-tightly delivered on tooth bar 6.At this, first the characteristic of driving element is used, motion is carried out with clear restriction, nonslipping and linear relation, and described relation allows to adjust when directly not determining piston displacement, because displacement is carried out via motor 2 really surely indirectly.Only reference stop is needed in the region (guidance field 11) that tooth bar guides.Access multistage, high velocity ratio can realize, structure space little as far as possible realizes commanding apparatus 1.
By worm driving device and gear/rack connection set, draw the linear nonslipping relation between the volume flow of the control system of the displacement of the rotor of motor 2/ motor 2 and the piston displacement/moving displacement of tooth bar 6 and then hydraulic pressure.No longer need the absolute displacement transducer for piston position.Worm gear (the first gear 4) together with the second connected gear 5 in production technology can according to friction pair be considered as sintered part or if desired even by strengthen, such as fiber strengthened (preferred carbon fiber, aramid fibre or glass fiber-reinforced) plastics form.Therefore, compared with planetary pinion rolling transmission mechanism so far, the cost of production of component can obviously reduce.The embodiment of second gear 5 and/or the first gear 4 with circle/circle completely allows motor 2 freely to locate around the axis of worm gear and gear (4,5) with the piston with tooth bar output unit.Thereby, it is possible to very freely utilize structure space and multiple different structure space can be used by different shell variation forms.In order to affect the power on worm gear 4 and gear 5, that can change worm gear 4 with diameter that is gear 5 and piston area and piston displacement.
The characteristic about self-locking of final controlling element/commanding apparatus 1 or can be affected by screw rod gradient about the characteristic of the ability for certainly opening.At this, also change the force transmission ratio relative to gear 4 in any case, to obtain the good relationship of motor rotations and volume flow.
