The backlash compensation element 13 of annular is arranged on by rivet 14 on the rear surface of first portion 3 of connecting plate 2, and rivet 14 is arranged in the long strip opening 15 of backlash compensation element 13.More particularly, the circular-arc relative connecting plate 2 of long strip opening 15 allowable clearance compensating element 13 has the angular play that value is between 0.3 ° to 1 °, is preferably about 0.8 °.
The radially inner periphery of backlash compensation element 13 comprises the spline section of being furnished with spline 16, and spline 9th district of the second portion 4 of these spline section and connecting plate 2 are similar.But the end of spline 16 and bottom do not have the end of spline 9 and bottom wide.
Backlash compensation element 13 comprises the window 17 for putting spring 8 of connecting plate 2 in addition.More particularly, the edge of window portion that is positioned at Fig. 2 the right is provided with the stop member 18 that supports described spring 8.Guide 41 extends spring inner in addition from stop member 18.
Grab 19 (Fig. 2) is pivoted on the rear surface of backlash compensation element 13 around rivet 20.Each grab 19 comprises and locks the front end 21 of spring 8 and elongated rearward end 22, and the rivet 20 that forms pivotal axis is positioned at the intermediate portion of grab 19.End 22 is sized to and makes center of gravity basic fixed position in rotating shaft right side, to during fabrication, especially ensure to keep the correct location of grab in the time of test phase.
Driving mechanism 1 comprises and the spline 24 of the spline fitted of connecting plate 2 in its radial outer periphery.Particularly, spline 9 and spline 24 are with a gap and are installed mutually.
This gap is necessary for convenient follower 2 is arranged on driving mechanism 1, and this installation especially can be carried out " blindly ".
This gap allows the relative connecting plate (or follower 2) of annular disk (or dirivig member 1) to relatively rotate, and the angular play between Zhe Liangge mechanism 1,2 is greater than the angular play between element 13 and connecting plate 2.
Driving mechanism 1 comprises the pawl 42 of radial inward projection in addition, and these pawls 42 are for the installation on the annular disk at double damping flywheel.
Certainly, this assembly is not limited to make double damping flywheel to connect with clutch.It also can be used for connecting other element of automotive drive.
To the operation of this transmitting assembly be described now.
In the time of operation, moment of torsion transmission can be carried out along two contrary sense of rotation, and these two sense of rotation are respectively that correspondence drives the forward (the arrow D in Fig. 1) of the direction of follower 2 by driving mechanism 1 and is called the oppositely contrary sense of rotation of (the arrow R in Fig. 1).
Especially, in the time that gearbox is positioned at neutral gear or clutch and is positioned at disengaging configuration and motor and applies braking torque and be so-called engine braking, can produce driving mechanism 1 and follower 2 along the oppositely rotation of R.In some applications, in the situation that also can switch in the sense of rotation of motor along reverse rotation, produce.
At first,, after the spline 24 interband unoccupied places of driving mechanism 1 are arranged in the spline 9 of follower 2, backlash compensation element 13 is positioned at off-position: backlash compensation element does not apply any power to the spline 9,24 of these mechanisms.
At this off-position (Fig. 2), the first end 25 of spring 8 is resisted against in the limit portion 18 of window 17 of backlash compensation element 13, and the second end 26 of spring 8 is resisted against on the front end 21 of grab 19.
Therefore, the end 25,26 of spring 8 is connected with backlash compensation element 13.
If transmit the operation along forward D, the spline 24 of driving mechanism 1 can be against the spline 9 of follower 2, and driving mechanism 1 thereby driving follower 2 rotate.
Once transmit along oppositely R operation, due to the gap between the spline 9,24 of these mechanisms, follower 2 is just with respect to driving mechanism 1 pivotable.
In the time of this (limited play) pivotable, the cam face 12 of pawl 11 leaves grab 19, and grab 19 is around the second end 26 (Fig. 3) of rivet 20 pivotables retracting spring 8.
So these ends 26, against the above pawl 11, make spring 8 promote backlash compensation element 13 again, backlash compensation element relatively follower 2 along the direction pivotable of arrow 27 indications in Fig. 2.The spline 24 of the spline 16 breasting driving mechanisms 1 of backlash compensation element 13, to compensate the gap forming between follower 2 and driving mechanism 1.Therefore, backlash compensation element 13 is in its working position.
Follow-up, along forward D or when oppositely R rotates, the gap between Zhe Liangge mechanism reduces or eliminates, can reduce like this noise and the wearing and tearing of these mechanisms in the time moving.
Once grab 19 is thrown off, the expansion of spring 8 just stops grab 19 to return to their initial lock position.
Be shown in Fig. 4 and Fig. 5 according to the transmitting assembly of the second mode of execution.It is from the different of last mode of execution, and connecting plate 2 does not comprise opening, does not comprise pawl yet.The pivotable of grab 19 obtains against connecing post 43 with connecting plate 2 all-in-one-pieces by the end 21 of grab, connects post 43 and for example obtains by extrusion moulding.
The rearward end 22 of grab 19 comprises in addition axial bending and is placed in the stop member 44 in the eyelet 45 of backlash compensation element 13.As seen in Fig. 5, stop member 44 is for the limit portion against eyelet 45 when the position in retracting spring 8 at grab 19.
The operation of this transmitting assembly is identical with the operation of the transmitting assembly of Fig. 1-3.
In Fig. 6-7, represent another mode of execution.This mode of execution is from the different of mode of execution of Fig. 1-3, and grab 19 is not mounted to around axle pivotable, but is connected with backlash compensation element 13 by the elastically deformable pawl 28 being fixed by rivet 20.Therefore,, in the time transmitting along reverse R operation, the cam face 12 of pawl 11 departs from the front end 21 (Fig. 7) of grab 19 by the distortion of pawl 28.As before, spring 8 promotes backlash compensation element 13 again, and backlash compensation element is relative follower 2 pivotables, to compensate the gap between the spline 24 of driving mechanism 1 (not shown) and the spline 9 of follower 2.
Fig. 8 and Fig. 9 represent the 4th mode of execution, and wherein, backlash compensation element 13 comprises some elastic locking tongue pieces 29 of circumferential extension.These tongue pieces 29 comprise that the first end 30 that is connected with the remaining part of backlash compensation element 13 and 31, the second locking ends 31, the second locking end are used to form the stop member of the second end 26 to spring 8 before release.
The binding site of tongue piece 29 is the locked position shown in Fig. 8, and in this position, tongue piece 29 leaves the plane of backlash compensation element 13.The rest position of tongue piece 29 is the unlocked position shown in Fig. 9, and wherein, tongue piece 29 extends in the plane of backlash compensation element 13.
Backlash compensation element 13 comprises some pawls 32 in addition, and these pawls 32 are for being resisted against some splines 24 of driving mechanism 1 (not shown).These pawls 32 comprise bearing surface, and the relative radial plane of bearing surface tilts, to adapt with the inclined surface of the spline 24 of driving mechanism 1.
Spring 8 is kept in place by some curved jaws 33 of backlash compensation element 13, and the first end 25 of spring 8 is resisted against on the pawl 34 of backlash compensation element 13.
Follower 2 comprises that spring 8 is placed in window wherein.The edge of window portion 35 relative with the pawl 34 of backlash compensation element 13 is for the second end 26 against spring 8.
The operation of the transmitting assembly of Fig. 8 and Fig. 9 is as follows.
After the spline 24 of driving mechanism 1 (not shown) is arranged in the spline 9 of follower 2, tongue piece 29 is maintained at the position that they are retrained by spring 8.More particularly, the free end 31 of tongue piece 29 is fixed by the second end 26 of spring 8.
Backlash compensation element 13 does not apply any power (off-position) on the spline 9 of follower 2 or the spline 24 of driving mechanism 1.
Carry out along forward D if transmitted, the spline 24 of dirivig member 1 will abut on the spline 9 of follower 2, so driving mechanism 1 drives follower 2 to rotate.
Once transmit along oppositely R operation, due to the gap between the spline 9,24 of these mechanisms, relative follower 2 pivotables of driving mechanism 1.
In the time of this (limited play) pivotable, the edge of window portion 35 facing with the second end 26 of spring 8 will be resisted against on end 26, and this just discharges tongue piece 29, so tongue piece returns to its rest position shown in Fig. 9.
8, spring forces the working position of backlash compensation element 13 in it, and in this working position, backlash compensation element is close to against the spline 24 of the driving mechanism 1 on the spline 9 of follower 2, to compensate the assemblage gap between these splines.
Figure 10 represents similar the 5th mode of execution of mode of execution with Fig. 8 and Fig. 9, and wherein, deformable tongue piece 29 is not by forming with backlash compensation element all-in-one-piece integrated member, but is made up of the member separating being fixed on backlash compensation element 13.
The 6th mode of execution is shown in Figure 11 and 12.In these figure, the first end 25 of spring 8 is against the bearing surface 36 of follower 2, and the second end 26 is against the notch 37 of follower 2, to lock spring 8.
After the spline of dirivig member 1 24 being installed in the spline 9 of driven member 2, spring 8 is in its position shown in Figure 11, and in this position, these springs apply any power (off-position) on backlash compensation element 13.
Once transmit along oppositely R operation, the pin of backlash compensation element 13 refers to that 38 by by by being pressed in Compress Spring 8 on the second end 26 of spring, therefore the second end of spring 8 26 is discharged into beyond notch 37, so that spring applies power (working position) on backlash compensation element 13.
Pin refer to 38 and the shape of notch 37 be suitable in the time that pin refers to 38 Compress Spring 8, carrying out spring 8 to be discharged into the operation outside notch 37.
Figure 13 represents seven mode of execution similar with the mode of execution shown in Figure 12 to Figure 11.But the difference of the 7th mode of execution is, the second end 26 of spring 8 carries spring seat 39, and each spring seat comprises the groove 40 of truncated cone shape.
Backlash compensation element 13 comprises that pin refers to 38, when along reverse R operation, sells and refers in 38 insertion grooves 40, and coordinate with the frusta-conical surface of groove 40, to discharge spring seat 39 from spline 37.
