Description
Technical field
The present invention relates to a kind of actuator and particularly for the clutch of operation vehicle.
Background technology
The rotational motion of one component can be transformed into the axial movement of another component by actuator.Actuator herein can
It is any kind of linear actuator, such as the slave cylinder of PWG actuators (PWG=planetary spindle drives), hydraulic pressure
Deng.
Planetary spindle drive (PWG) or planetary roller screw transmission mechanism are by leading screw, feed screw nut and at it
Between planet rolling body on ring week, being contained in planet carrier be set formed.Here, leading screw, feed screw nut and planet rolling
Kinetoplast has profile portion, to transmit rotational motion, wherein component between leading screw and feed screw nut --- leading screw or leading screw spiral shell
It is female --- in one be rotated driving, and another component in the case where anti-rotating is arranged along the shifting of the longitudinal axis of leading screw
The axial stroke corresponding to set transmission ratio is moved.Here, there are two different outline segments for planet rolling body tool, it is described
On the one hand outline segment is engaged with leading screw and is on the other hand engaged with feed screw nut, a profile wherein on planet rolling body
Section is that another outline segment on ditch flute profile and planet rolling body is typically ditch flute profile, and according to embodiment,
Complementary thread section is arranged on leading screw or feed screw nut, and correspondingly groove section is arranged on other component.
For example known PWG from 320 621 A1 of EP, wherein leading screw are with screw thread and feed screw nut is with groove, row
Star rolling element is rolled by means respectively of the outline segment that respective complementary is constituted on the groove.Here, axial restraint bearing
And the feed screw nut being for example arranged relative to anti-rotating by the leading screw of electro-motor rotation driving rotates so that feed screw nut is forced
Ground and axially displaced by planetary rolling of frictional fit in the groove of feed screw nut.Here, in the axis of feed screw nut
The movement proportional to screw rotation velocity is obtained on stroke.
Especially overcoming in for example by means of the lead-screw drive mechanism (such as PWG) of the optimization efficiency of electrical motor driven
Load, for example clutch indicatrix acting actuator in, for example hydrostatic clutch actuator (Hydrostatic
Hydrostatic clutch actuator-abbreviation the HCA of Clutch Actuator) the problem of be：In the feelings for needing holding position
It needs to keep electric current in electro-motor under condition and then needs holding torque, because lead-screw drive mechanism (such as in PWG) is no
It is self-locking.It is driven in leading screw in PWG in the HCA with anti-rotation teeth ring nut, preferably rolling
The additional reduction of (such as in the planetary gear mechanism of engagement/do not skid) progress guide screw lead, described in dynamic movement
Additional reduction can be freely selected by changing leading screw diameter and/or planetary roller diameter within the limit, wherein in institute
It states to obtain on gear ring nut and is axially moved (relative to leading screw).The decisive disadvantage of this actuator is：The actuator needs
The holding electric current to be continued can not be protected in the case where losing electric current/fault condition (such as rupture of line, plug from falling)
Hold position.Then there are Risks in the clutch pressed off by actuator：Undesirably it is closed clutch.
In addition, it is for example known for clutch that will embrace spring.
In the not yet disclosed technical solution of applicant, the component with rubbing device, the friction dress are proposed
Setting has at least two components that can mutually rotate, and the component is particularly for operating vehicular clutch, wherein can be with respect to that
Being provided between the component of this rotation influences the helical spring of efficiency/friction when component relatively rotates.Here, helical spring is extremely
It is formed locally less and embraces spring, described armful of spring can be single winding spring, double winding springs or winding-torsionspring.It is described herein
Double winding springs tool there are two the zone of action, the zone of action is axially set gradually.
Known solution is had in common that from the prior art：Spring is embraced to be surrounded by PWG sleeves and with use
In each rubbing surface of the sleeve and gear ring for PWG.Ground is determined by function, gear ring and sleeve are made of steel.Due to
For friction part have high moment of friction steel-steel frictional pair, also in relation with lubricant it can be expected to " erosion " (cold welding) in turn
It is contemplated to the loss and abrasion of raising, it is impaired until component failures that this can result in function.
In addition, gear ring is not driven shape-ordinatedly, but driven by planetary roller frictional fit.It is high in axial force
In the case of, the structure be not it is crucial because gear ring by planetary member by torque actuated, the torque is more than friction element
Torque.Problematic is following loading condition, and wherein planetary member acts on the system that the driving moment on gear ring is less than friction element
Kinetic moment.In this case, without the driving of gear ring and planetary member relative to gear ring or --- according to frictional behavior ---
It is slided relative to leading screw.The frictional force to work is since small axial force is same small and only small amount becomes the gross efficiency of PWG
Difference, however the loading condition is usual or occurs on longer path/period, it is thus possible to there is local loss, institute
It states loss distortion and rolls geometry.In this case, it can result in：Even if planetary member is in driving moment relative to friction element
It is not rolled in the case of sufficiently large yet and then significantly increases abrasion with higher power, and can result in the premature mistake of component
Effect.
