Tri-state overrun clutch
In the present invention, except the wedging direction of voussoir is opposite each other (as shown in Figure 3 and Figure 4), first tri-state overrun clutch of combination preferably has identical structure with second tri-state overrun clutch.Therefore, main below structure and the working method thereof to first tri-state overrun clutch is specifically described.
Fig. 2 is the part assembling stereogram of a kind of first tri-state overrun clutch of using of the present invention, and promptly voussoir is kept by inside and outside retainer.Fig. 3 is the partial sectional view of tri-state overrun clutch among Fig. 2.
Before first tri-state overrun clutch is elaborated, at first need to prove: outer ring 1A is generally ring structure, and as the outer ring of existing common mono-directional overrun clutch, the first working surface 31A of voussoir 3A is relative with the inner peripheral surface of this outer ring; Inner ring 2A can be ring structure, as the inner ring of existing common mono-directional overrun clutch, also can be solid shaft as shown in the drawing, and the second working surface 32A of voussoir 3A is relative with the outer peripheral surface of this inner ring.
As shown in Figures 2 and 3, first tri-state overrun clutch can comprise outer ring 1A, inner ring 2A, a plurality of voussoir 3A between outer ring 1A and inner ring 2A, and the outer retainer 41A and the interior retainer 42A that between outer ring 1A and inner ring 2A, keep described a plurality of voussoir 3A.The working surface of the described outer ring 1A of the permanent contact of the first working surface 31A of described a plurality of voussoir 3A.The second working surface 32A of described a plurality of voussoir 3A can correspondingly contact or leave the working surface of described inner ring 2A by the rotation of voussoir 3A.In Fig. 3, the working surface of the second working surface 32A of voussoir 3A contact inner ring 2A.The angle if voussoir 3A turns clockwise, then the second working surface 32A will move with respect to the left-hand side of inner ring 2A in Fig. 3, thereby leave the working surface of inner ring 2A.
In this tri-state overrun clutch, can have a plurality of arc groove 11A on the working surface of outer ring 1A, each arc groove 11A and first of a corresponding voussoir 3A.Working surface 31A matches, and the described first working surface 31A is remained in this arc groove 11A.Interior retainer 42A has axially outwardly directed a plurality of lug 6A, has the inclined hole 61A with respect to axioversion on each lug 6A.In addition, as Fig. 1, can be provided with on the excircle of outer ring 1A and axially slidably stir dish 8A (also will be described in detail in the back), this is stirred on the dish 8A and is fixed with a plurality of turning lever 81A that are inserted into separately among the corresponding inclined hole 61A.By the interaction between interior retainer 42A and the arc groove 11A, voussoir 3A can center on its pivot pin end (being the described first working surface 31A) and rotate between Internal and external cycle, thereby makes the second working surface 32A opposite with the described first working surface 31A of voussoir 3A correspondingly contact or leave the working surface of inner ring 2A.
In addition, can offer the reaming 62A that width increases at the end of inclined hole 61A.Reaming 62A can be arranged on any two ends of inclined hole 61A.In this case, when needing tri-state overrun clutch to use as traditional mono-directional overrun clutch, the turning lever 81A that stirs on the dish 8A is moved in this reaming 62A, can prevent to influence the proper functioning of tri-state overrun clutch thus owing to misoperation.As a kind of substitute mode, the outer end of inclined hole 61A can be arranged to open wide, and this also can realize this security function to a certain extent.
Stable the remaining in the arc groove 11A of the first working surface 31A in order to ensure voussoir 3A, can between inner ring 2A and outer ring 1A, preloading spring 5A be set, be used to produce pretightening force the described first working surface 31A is pressed in the described arc groove 11A, and can make described voussoir 3A that a kind of trend of rotating towards the wedging direction is arranged.This preloading spring 5A can use normally used preloading spring in the existing mono-directional overrun clutch.
In above-mentioned tri-state overrun clutch,, can on the 1A of outer ring, be in axial sliding by controlling the above-mentioned dish 8A (as a kind of control mechanism) that stirs for the position of the voussoir 3A between outer ring 1A and the inner ring 2A is regulated or controlled.When stirring dish 8A when endwisely slipping, stir turning lever 81A on the dish 8A and can be on interior retainer 42A slide among the inclined hole 61A of extended lug 6A.Because retainer 42A rotated corresponding angle with respect to outer ring 1A in inclined hole 61A with respect to the axis tilt several angle, therefore can drive.Simultaneously, because the first working surface 31A of voussoir 3A is securely held in the arc groove 11A on the working surface of outer ring 1A, so the voussoir 3A that is kept by interior retainer 42A and outer retainer 41A just can rotate corresponding angle around the described first working surface 31A between inside and outside circle, thereby can cause the second working surface 32A on the voussoir 3A correspondingly to leave the working surface of inner ring 2A, inside and outside thus circle can freely rotate in positive and negative two-way realization.
Stir that dish 8A endwisely slips, circumferentially locking can be realized by any suitable means on the excircle of outer ring 1A, for example can be by habitual strong-groove combination, perhaps spline connects.As a kind of embodiment of the present invention, can be at described axial raceway 83A, the 13A that stirs on the internal surface that coils 8A and correspondence is set respectively on the outer surface of described outer ring 1A, and a plurality of roller 84A are set in described raceway 83A, 13A, for example steel ball can be realized stirring dish 8A thus easily and endwisely slip on the excircle of outer ring 1A.
Stirring dish 8A can drive by any suitable means well known in the art, for example can be by manual, electronic, Electromagnetic Drive, surge, pneumatic or the like means realize.As a kind of embodiment of the present invention, stirring dish 8A can endwisely slip on the excircle of outer ring 1A by shifting fork mechanism or electromagnetic mechanism driving.
As shown in Figure 1, described outer ring 1A can be configured to the shape of a secondary multidiameter shaft, will stir dish 8A simultaneously and be arranged on the small diameter portion of this multidiameter shaft, can make the structure of free wheel device compact more thus.In the case, at the step part of multidiameter shaft a plurality of window 12A should be set correspondingly, the lug 6A in making on the retainer 42A can pass corresponding window 12A and stretch out.In addition, inner ring 2A also can be configured to the shape with the corresponding secondary multidiameter shaft of described outer ring 1A, thereby can make the structure of free wheel device compact more.
As shown in Figure 1, can between inner ring 2A and outer ring 1A, bearing 7A be set, this bearing 7A can fix by the shaft shoulder on inner ring 2A and the outer ring 1A and/or back-up ring 10A respectively, thereby can realize the accurate location radially between inner ring 2A and the outer ring 1A, guarantee that free wheel device is stable, work reliably.
When using composite type overrunning clutch of the present invention, the outer end of inner ring can be imported with outside power or output unit be connected by connecting element such as coupling, for example the input shaft of the rotating shaft of drive motor or gearbox etc.If inner ring is the ring structure of hollow, then can be directly on the inner peripheral surface of inner ring outer end or outer peripheral surface, form keyway or other connecting element, so that be connected with the power input or the output unit of outside.In addition, on the outer ring, also connecting element can be set, be used to connect outside power input or output unit.
Fig. 4 be with Fig. 3 in the cross-sectional schematic of second tri-state overrun clutch that is used in combination of first tri-state overrun clutch.Fig. 4 is mainly used to illustrate that the wedging direction of voussoir in the wedging direction of voussoir in first tri-state overrun clutch and second tri-state overrun clutch is opposite each other.That is to say that as shown in Figure 3 and Figure 4, if the wedging direction of voussoir 3A is a clockwise direction in first tri-state overrun clutch, then the wedging direction of voussoir 3B is exactly counterclockwise in second tri-state overrun clutch.In addition, the others of these two tri-state overrun clutch can be identical.
Fig. 5 is the part assembling stereogram of another kind first tri-state overrun clutch that uses of the present invention, and promptly voussoir is kept by inside and outside retainer.Fig. 6 is the partial sectional view of tri-state overrun clutch among Fig. 5.
As shown in Figure 5 and Figure 6, compare with the first above-mentioned tri-state overrun clutch, the difference of this tri-state overrun clutch is: arc groove 11A is not set on the working surface of outer ring 1A, but by outer retainer 41A is fixed on the 1A of outer ring, realize relatively rotating between outer retainer 41A and the interior retainer 42A, thereby realize the rotation of voussoir 3A.
Particularly, described outer retainer 41A can be fixed on the 1A of outer ring for example bolt connection, riveted joint, clamping or the like by any known means in related domain.As an example, on the retainer 41A protruding 43A is set outside, corresponding groove 13A is set on the working surface of outer ring 1A simultaneously, described protruding 43A is inserted or remains in the groove 13A, outer retainer 41A can be fixed on the 1A of outer ring.Retainer 42A is provided with above-mentioned lug 6A in described, and is same as the previously described embodiments.Therefore, retainer 42A rotates with respect to outer retainer 41A in the lug 6A drive by stirring, and just can realize the rotation of voussoir 3A between Internal and external cycle, thereby realize the two-way mask work state of this tri-state overrun clutch.
As mentioned above, except the wedging direction of voussoir was opposite each other, this structure of this first tri-state overrun clutch can all be applied in second tri-state overrun clutch.The present invention no longer is repeated in this description the structure of second tri-state overrun clutch.
Need to prove that in addition as shown in Figure 1, the outer ring 1A of first tri-state overrun clutch and the outer ring 1B of second tri-state overrun clutch are in the same place as bolton by fastening piece 9, this mainly is a convenience of considering processing and assembling.That is to say, if structure of the present invention is suitably revised, under the prerequisite that can conveniently make and assemble, these two outer ring 1A and the 1B member that also can form as one.
Below with reference to Fig. 3 the work characteristics of first tri-state overrun clutch is carried out simple declaration.
When the second working surface 32A of voussoir 3A left the working surface of inner ring 2A, tri-state overrun clutch was in two-way separated state, and outer ring 1A and inner ring 2A can two-wayly freely rotate positive and negative.
When the second working surface 32A of voussoir 3A contacts the working surface of inner ring 2A, if the clockwise direction among Fig. 3 is defined as forward, counterclockwise be defined as oppositely, then:
If-inner ring 2 forward rotation, and tri-state overrun clutch is in the forward jointing state, and then inner ring 2 drives outer ring 1A forward rotation.
If-inner ring 2 forward rotation, and tri-state overrun clutch is in forward and surmounts state, then outer ring 1A also forward rotation and rotating speed greater than the rotating speed of inner ring 2.
If-inner ring 2 backward rotation, and tri-state overrun clutch is in the reverse engagement state, and then outer ring 1A drives inner ring 2 backward rotation.
If-inner ring 2 backward rotation, and tri-state overrun clutch is in and oppositely surmounts state, then 1A reverse speed in outer ring is less than inner ring 2 or be in forward rotation.
This shows that the working state of tri-state overrun clutch depends primarily on the turning to and rotating speed of wedging direction, outer ring and inner ring of the position of voussoir, voussoir.By above-mentioned explanation, the used tri-state overrun clutch of the present invention is very clearly to those skilled in the art.On this basis, below composite type overrunning clutch of the present invention is described.
Composite type overrunning clutch
