Technical field

The disclosure relates generally to surmount coupling arrangement, such as one-way clutch or brake, and relate more specifically to Selectable one-way couples (SOWC) device and/or automatically controlled unidirectional connection (EOWC) device, and the selectable one-way couples (SOWC) Device and/or automatically controlled unidirectional connection (EOWC) device include the strut that can be disposed and with the Electromagnetically actuated of clast storing apparatus Device, the electromagnetic actuators provide the unexpected deployment of improved anti-ferromagnetically pollution and strut.

Background technique

This part provides background information related with the disclosure, which is not necessarily the prior art.

Automatic transmission provides multiple forward directions by selectively activating one or more clutches and/or brake With inverted speed ratio or transmission ratio, it is drivingly connected with establishing torque transmitting between speed changer input and speed changer output to be used for Motive power (that is, driving torque) is supplied to power train from the dynamical system in motor vehicles.It is widely used in automatic transmission A type of brake or clutch be commonly referred to as one-way clutch (OWC) surmount coupling arrangement, this surmounts connection Connection device is in a seat ring in its seat ring (radially coupling configuration) or one in its driving plate (being in axially coupled configuration) Driving plate is surmounted relative to another seat ring or driving plate when rotating on first (that is, being freely rotated) direction, and the It engages or locks on two (that is, locking) directions.In general, locking component associated with one-way clutch such as strut can with It is moved between the deployed position that the non-deployed position of mode " is freely rotated " in foundation and is used to establish " locking " mode.Strut is logical A location bias in two positions of Chang Chaoxiang strut.This conventional one-way clutch cannot be to this conventional unidirectional The operation mode --- that is, whether this conventional one-way clutch locks or be freely rotated in two directions --- of clutch Independent control is provided, and this conventional one-way clutch is commonly known as passive one-way clutch.Therefore, basic list The direction of input seat ring or driving plate is applied to based on driving torque to clutch and " locking " is provided in one rotational direction Mode and in the opposite direction offer " being freely rotated " mode.

However, there are following requirements in modern automatic transmission: being wherein commonly known as selectable one-way clutch (SOWC) or " controllable " of automatically controlled one-way clutch (EOWC) surmounts coupling arrangement can be controlled selectively into offer additional Functional performance mode.Specifically, controllable one-way clutch device can be freely rotated with that can provide in two rotational directions Mode, until command signal (that is, coming from gearbox controller) makes power operation formula actuator that coupling arrangement is switched to connection Until the locking mode of connection device.Therefore, controllable one-way clutch device can provide defeated on one or two direction of rotation Enter the drive connection between component and output link, and controllable one-way clutch device can be can be operable at one or two It is freely rotated on a direction.In modern automatic transmission it is also known that by passive one-way clutch and controllable one-way clutch Device is integrated in the combination coupling arrangement of commonly known as bidirectional clutch.

In some cases, controllable one-way clutch device surmounts coupling arrangement simultaneously selectively to activate using hydraulic actuator Switch between available operation mode.It it is known that using the electromechanical actuator with controllable one-way clutch device.It is replaced as another For scheme, it is directed to the electromagnetic actuators for being used together with controllable one-way clutch device recently and has carried out many exploitations.In In many electromagnetic actuators, commonly known as the rocker-type locking member of strut in response to coil block excitation and from first It sets and is switched to the second position.

In some controllable one-way clutch devices, electromagnetic actuators have directly effect configuration, so that strut is the one of magnetic circuit Part, and the pivoting action of strut is as being applied directly to caused by the attraction of strut by the excitation of coil block. It is firm and reliable to provide therefore, it is necessary to be accurately controlled in the air gap established between core/pole piece of coil block and magnetic strut Lock function.As an alternative, some controllable one-way clutch devices are equipped with electromagnetic actuators, between which has Effect configuration is connect, in the indirectly-acting configuration, intermediate member such as armature or linkage arrangement are at swashing in response to coil block Encourage and cause the pivoting action of strut.

During the exploitation test of controllable one-way clutch device, it is determined that at least one problem for needing to solve.Specifically, In Under certain operating conditions of automatic transmission, excessive oil is generated near the strut that can be disposed in controllable one-way clutch device Position, this may potentially result in unexpected " the hydraulic deployment " of strut.It is unexpected that hydraulic deployment be strut due to acting on Barometric gradient on strut and the state that the deployed position of strut is moved to from the non-deployed position of strut, cause with power operation formula The actuating of dynamic device is unrelated.The barometric gradient is combined to be caused with the associated fluid dynamics of fluid flow around clutch components Act on the force vector on the end sections of strut.When the size of this hydraulic coupling on the end sections for acting on strut increases When, hydraulic coupling finally overcomes the bias being applied on strut by strut reset spring to set power, so as to cause the unexpected of strut Partial deployment or completely deployment.This unexpected hydraulic deployment may result in strut " engagement (ratchet) " inside race/ In driving plate, so as to cause branch lever system and/or armature premature fatigue failures associated with power operation formula actuator.And And impact may result in armature/strut configuration deformation, and then cause to lead since strut may only have partial deployment ability The forfeiture of latch function.

Another problem of determining electromagnetic actuators is related to polluting dduring test.Specifically, contained by what oil carried The clast and pollutant of iron can be attracted to the magnetic field generated by electromagnetic actuators, and finally produce to the operation of electromagnetic actuators Raw adverse effect.For example, this clast is disposed comprising may cause the deployment of part strut or 'inertia' strut.In disassembly analysis When, it has been noted that clast along pole piece associated with coil block matching surface and with indirect-type strut actuated phase Associated armature is collected.Basic reason analysis confirms: this undesirable inertia strut deployment is since this clast disturbs Caused by the proper motion of armature.In order to solve this problem, it is developing using independent solenoid actuator and is moving The controllable one-way clutch device of non magnetic strut (that is, directly acting on) or non magnetic armature (indirectly-acting).However, solenoid-actuated Device possibly can not generate enough power requirements for strut deployment in all applications.

Therefore, it is necessary to continual exploitations to be used for the improved electromagnetic actuators used in controllable one-way clutch device, the improvement Electromagnetic actuators solve the problems, such as and overcome the deployment of such as hydraulic strut and clast pollution etc with provide enhancing function and Packaging.

It, can be in conjunction in any clutch pack embodiment discussed herein and such as to this referring to Fig. 8 to Figure 10 The active fulcrum bar component 548 in the other clutch pack embodiments being readily apparent is accepted in for the technical staff of field In the strut tank 533 of outer race 522, in Fig. 8 into Figure 10, run through several attached drawings, the similar appended drawing reference that deviation is 500 Indicate corresponding component.Each active fulcrum bar component in active fulcrum bar component 548 can have coil block by actuating 552 electromagnetic actuators 551, armature 560, bias spring 561 and active strut 550 operates.

Active strut 550 includes base section 86 and lock arm 87.Lock arm 87 extends to keyed end from base section 86 Portion or edge 88.Base section 86 is pivotally arranged in strut tank 533 in latched position (Fig. 9) and unlocked position (Fig. 8 And Figure 10) between be pivoted movement.In latched position, lock-in edge 88 engages the outer ratchet 544 of inside race 536, and Unlocked position, lock-in edge 88 and the outer ratchet 544 of inside race 536 are radially spaced apart.The setting of bias spring 561 is held in strut Extend in slot 533 and between base section 550 and the base portion or bottom plate of strut tank 533, by 550 direction of active strut Unlocked position biasing.

Coil block 552 include across bobbin 556 central corridor be arranged permeability magnetic material core 554, wherein at least one A coil 558 is directly wound on bobbin 556 and therefore can operate the magnetic flux will be generated by coil 558 around core 554 It focuses on around core 554.

Armature 560 extends between first end 90 and the second end 92, and first end 90 is rested upon in actuator tank 532 Armature part 91 in be pivoted movement in armature part 91, the second end 92 extends in strut tank 533 and prolongs It is stretched into and is engaged with the base portion 86 of active strut 550.Armature 560 is shown as with bifurcated supporting leg (bifurcated legs) 93, Bifurcated supporting leg 93 is formed with channel therebetween, wherein the part that channel is sized to reduce the width of active strut 550 is with shape It is received in the channel at the mode in gap, wherein each supporting leg 93 extends along the opposite side of active strut 550.Armature 560 First end 90 is in the armature part 91 that pivotal track 94 is pivotally arranged at tank 532, in response to coil 558 It is powered and is radially inwardly directed between actuated position and non-actuated position and is pivoted far from core 554.In actuated position, armature 560 It is pulled to core 554, then the driving of active strut 550 is arrived latched position and the engagement with base section 86 by supporting leg 93.In Non-actuated position, armature 560 are spaced apart with core 554 and allow bias spring 561 that active strut 550 is biased to unlocked position. Armature 560 has the upper bending section 95 and the lower bending section adjacent with the attachment area of supporting leg 92 being located in each supporting leg 92 96, so that upper bending section 95 and lower bending section 96 are between first end 90 and the second end 92.

It is important that --- especially when clutch pack 520 is on automobile component ---, active strut 550 is only connect The outer ratchet 544 of inside race 536 is closed, subsequent coil block 552 is energized to that active strut 550 is expectedly moved to locking bit It sets.Therefore, to the resistance (the high g power on certain directions other than simple gravity) of inertia load for clutch pack 520 operation is important.The most popular method for resisting high inertia load is the bias spring 561 for utilizing higher force.Although should Method is quick Solution, but there is disadvantage associated with this method.One the disadvantage is that by inclined during routine operation The increased resistance of the offer of spring 561 is set, this needs to increase the size of armature 560 and/or coil block 552 and thickness to generate Necessary increased magnetic force overcomes the increase of the spring force applied by biggish spring 561 in turn.It is this biggish in order to accommodate Component, tank 532,533 may also need to be bigger, to increase the overall dimensions and weight of clutch pack 520.

As the alternative solution for the size for increasing above-mentioned features/components, active strut 550 in armature 560 The substantially central portion extended between supporting leg 93 point includes the protrusion 97 with general triangular cross section, and protrusion 97 is along lock arm 87 a part lengthways extends, wherein protrusion 97 from the center portion of lock arm 87 extend outward into away from each other with accordingly Supporting leg 93 at superposed relationship.Each protrusion 97 in protrusion 97 is assembled and is terminated at substantially sharp keen edge 98.In addition, shoulder Portion 99 is limited by the upper bending section 95 in the supporting leg 92 of armature 560 or is arranged to adjacent with upper bending section 95.Shoulder 99 is configured to It is mobile towards locking direction to limit strut 550 by the engagement of edge 98 of the protrusion 97 of active strut 550, unless passing through coil group In addition the energization of part 552 activates.Therefore, during the application of inertia force, protrusion 97 and the purposive engagement of shoulder 99 make to prop up Bar 550 stops rotating upwards, to prevent the outer ratchet 544 of inside race 536 from engaging with the lock-in edge 88 of active strut 550 (as being best shown in Figure 10).

Fig. 8 shows coil 558 in position is not powered on, and wherein active strut 550 is in the unlocked position.In addition, Fig. 9 shows Coil 558 is gone out and has been in on-position, to make active strut 550 as was expected to be switched to latched position.Figure 10 is shown High inertial load is applied to clutch pack 520 on radial inwardly direction (as shown by arrows) the case where.In this feelings Under condition, armature 560 slightly rotates clockwise under inertial load, however, due to abutment shoulder 99 and protrusion 97 in armature 560 Lock-in edge 98 between the expected interference established, active strut 550 is blocked and is prevented from further rotation counterclockwise.Cause This, the interference between the edge 88 of protrusion 97 and the shoulder 99 of armature 560, which considerably increases, makes active strut 550 against inside race The mobile required power of 536 outer ratchet 544, but not will increase the sum that 560/ coil block 552 of armature is such as command by and be expected So that active strut 550 is pivoted required load capacity.

It should be understood that the protrusion 97 of strut 550 and the shoulder 99 of armature 560 can be used for other active fulcrum bar components Configuration is to resist high inertia load.

Referring now to fig. 11 to Figure 14, clutch pack 600 is shown generally as being suitable for two-way clutch device assembly 20 (Fig. 1 to Fig. 3), 120 (Fig. 4), 200 (Fig. 5 A), 300 (Fig. 5 B), 420 (Fig. 6 to Fig. 7) and 520 (each of Fig. 8 to Figure 10) Two-way clutch device assembly, particularly modification shape suitable for controllable one-way clutch device associated with each alternative embodiment Formula.Particularly, clutch pack 600 includes being combined with multiple controllable one-way clutch devices disposed and prevent feature, the multiple portion Administration prevents that feature from aiming to solve the problem that and minimum/inhibition due to the fluid in speed changer and/or clutch pack 600 acts on master The unexpected deployment of active strut caused by hydraulic effect on dynamic strut.However, the hydraulic deployment being described below Feature is prevented to be also applied for the passive one-way clutch for identical purpose, and those skilled in the art will appreciate that easy will These features are integrated to the ability in any strut-type or rocker-type one-way clutch.Similarly, although above-mentioned clutch pack In each clutch pack include the active branch for being configured to dispose active strut using armature when activating electromagnetic actuators Bar assembly, but the hydraulic deployment of the disclosure prevents feature to be equally applicable to have the controllable unidirectional of " direct " strut actuated It clutch and is equally applicable to replace the other types of removable locking member that uses of strut.

Clutch pack 600 includes the clutch module with outer race 602 and inside race 624.Outer race 602 is around axis A extends and including outer ring section 604, inner ring section 606 and the plate portion between outer ring section 604 and inner ring section 606 Section 608.The lug 610 being formed in outer ring section 604 is arranged for cooperating with the first component.As mentioned, first Part can be fixed the rotary part of case of transmission or such as axis etc.Outer ring section 604 further includes limiting actuator One or more actuator boss 612 of tank 614, armature tank 616 and strut tank 618.Finally, inner ring section 606 Including multiple inclined interior ratchets 620, interior ratchet 620 extends internally and is evenly distributed around axis A.

Although only symbolically showing, inside race 624 also extends around axis A.The inside race of clutch pack 600 624 are understood to substantially similar in the inside race 36 structurally and functionally with clutch pack 20.Therefore, inside race 624 has The outer rim section that is radially arranged between the outer ring section 604 of outer race 602 and inner ring section 606 and from outer race 602 The inner rim section that is disposed radially inwardly of inner ring section 606.The inner rim section of inside race 624, which has, to be used for and second component Cooperate the internal torque transferring structure (that is, lug or spline) of engagement.Finally, the outer rim section of inside race 624 includes multiple inclining Oblique outer ratchet, these outer ratchets extend radially outwardly and are evenly distributed around axis A.

Passive one-way clutch (not shown) it is associated with clutch pack 600 and also comprise by inside race 624 with Multiple passive struts that pivotable mode supports.Passive strut can be moved to engage in the inner ring section 606 of outer race 602 Interior ratchet 620.As previously mentioned, passive strut be configured to engage interior ratchet 620 with prevent outer race 602 and inside race 624 it Between the relative rotation along first (locking) direction, while allow between outer race 602 and inside race 624 along second (freely Rotation) direction relative rotation.

Controllable one-way clutch device 630 associated with two-way clutch device assembly 600 includes at least one electromagnetic actuators mould Block, each electromagnetic actuators module are accepted in the correspondence actuator boss 612 in outer race 602.Each electromagnetic actuators Module includes active fulcrum bar component 632 and electromagnetic actuators 638.Each active fulcrum bar component 632 includes active strut 634 With armature 636.Equally, each active strut 634 is pivotably supported in strut tank 618, relative to shape At ratchet outside the inclination in the outer rim section of inside race 624 between locking (deployment) position and unlock (not disposing) position It is mobile.In latched position, the engagement end portion 634a of active strut 634 is switched to engagement inside race 624 relative to outer race 602 On outer ratchet to establish the position of lock-up clutch mode.On the contrary, when being located at the unlocked position of active strut 634, actively The engagement end portion 634a of strut 634 is radially shifted and with the outer ratchet disconnect engagement on inside race 624 to establish unlock clutch Device mode.

Each armature 636 is pivotably supported in the armature tank 616 of actuator boss 612 and machinery Ground is connected to corresponding active strut 634.When armature 636 is located at attraction or actuated position relative to actuator 638, actively prop up Bar 634 is located at its deployed position.Do not attract or the position of unactuated position is led on the contrary, armature 636 is in relative to actuator 638 Active strut 634 is caused to be located in the non-deployed position of active strut 634.Reset spring 640 is kept and is acted on by outer race 602 On the tail end 634b of each active strut 634, so that routinely active strut 634 is biased towards its non-deployed position, this Again by armature 636 towards not attracting location bias.Reset spring 640 alternatively acts directly on armature 636.Electromagnetism causes Dynamic device 638 is supported in the actuator tank 614 of actuator boss 612, and electromagnetic actuators 638 have and armature 636 The coil block being radially spaced with strut 634.As previously mentioned, coil block include permeability magnetic material core, around core bobbin, And the coil windings around bobbin winding.As it is known, the energization of coil block establishes the magnetic between core and armature 636 Gravitation, the magnetic attraction is for overcoming the biasing of reset spring 646 that armature 636 is not attracted position pivotally from armature 636 It is moved to the attraction position of armature 636 and active strut 634 is moved to active strut from the non-deployed position of active strut 634 634 deployed position.

Various aspects according to the present invention, many different deployment inhibitory characters and outer race 602, active strut 634 and rank At least one of iron 636 is associated.These feature configurations are by solution (address) and negative function in active strut group On part 632 or the fluid dynamics of the fluid of surrounding and flow behavior inhibit the unexpected (that is, non-through of active strut 634 Electricity) deployment, generally it is determined as " hydraulic deployment ".It is unexpected that hydraulic deployment be due to acting on the barometric gradient on strut And the state for keeping strut mobile towards the deployed position of strut from the non-deployed position of strut.The barometric gradient with and inside race 624 relative to outer race 602 the associated fluid dynamics of rotation combine when lead to the abutting end for acting on active strut 634 Force vector on portion 634a.As the hydraulic caused power on the end 634a for acting on active strut 634 increases, the power is final The bias force for overcoming the application of reset spring 640, keeps cold in electromagnetic actuators 638 so as to cause active strut 634 In the case of towards active strut 634 deployed position unexpected pivoting action.Therefore, clutch pack 600 is used as inefficient Fluid pump.

One solution of this undesirable pump behavior is to increase anti-deployment feature, and anti-deployment feature is for making to come from The fluid stream of the sensitizing range of selectable one-way clutch 630 is turned to or is redirected or for reducing the stream in other regions Body pressure, to reduce due to being freely rotated what associated fluid motion generated relative to outer race 602 with inside race 624 The hydraulic deployment power being applied on active strut 634.For this purpose, being increased to all parts of controllable one-way clutch device 630 multiple Remodeling and/or feature.Below to the description of each feature without specific sequence or correlation or functionality.
