Embodiment
Show according to torque transmitter of the present invention with the illustrated form of vertical profile among Fig. 1, it is totally represented with reference character 10.This device comprises tubulose driving element 12 and the drive element 14 that is connected with this driving element 12.Drive element 14 is admitted the left field of driving element 12 in its right side area.
From Fig. 1 and Fig. 2, as can be seen,, make driving element 12 have stop surface 18 and drive element 14 has the opposed stop surface 20 of correspondence with profiling mode design driven element 12 axial overlap joint zone 16 with drive element 14.Stop surface 18 forms motion-stopping structure 40 and opposed motion-stopping structure 42 respectively with opposed stop surface 20 on the whole outer circumferential face of driving element and drive element.
Form midfeather radially between stop surface 18 and the opposed stop surface 20, this midfeather is filled in the following manner.At first, this midfeather comprises yarn inserting member 22.In addition, in this midfeather, be provided with each metal tape 24 that extends vertically.Yarn inserting member 22 all is embedded in the rubber layer 26 with metal tape 24.Thereby driving element 12 is connected with drive element by this way, that is: make driving element to rotate around longitudinal axis A with respect to drive element because of transmitting torque.This rotation at first produces under the shear stress of rubber layer.Yet,, resistance is increased gradually owing to yarn inserting member 22 resists any further rotation along with the increase of relative angle of rotation.Metal tape 24 also stops further rotation relatively.Finally, in the zone of stop surface 18 and opposed stop surface 20, yarn inserting member 22 all is compressed into the degree that can not further surrender substantially with rubber layer 26.Further moment of torsion transmission directly takes place under no any further counterrotating situation between driving element 12 and the drive element 14.
As a result, the torsional vibration with progressive nature can be cushioned, up to finally with maximal phase between the drive element 14 the angle of rotation place being produced direct moment of torsion transmission and relative angle of rotation can further not increase again at driving element 12.It should be noted that the free end 28 and 30 according to torque transmitter of the present invention 10 illustrated in figures 1 and 2 can be used for connecting two axle heads, particularly connect two axle heads that preferably are attached thereon of cardan shaft by welding.
In addition, as can be seen from Figure 1, when applying enough big axial force and corresponding opposing force to driving element 12 and drive element 14, these two elements can collapse the nested promotion of mode, thereby destroy being connected via rubber layer 26 between driving element 12 and the drive element 14.This is at (for example wishing situation that transmission system collapses under) advantageous particularly under the situation about having an accident.Particularly when engine block was pushed in the vehicle owing to accident, in order to prevent not controlled bending or the dissimilar distortion that takes up space, the expectation cardan shaft was collapsed.
Fig. 3 represents according to modification of the present invention.Use with Fig. 1 in identical reference character, still prefix number " 1 " in addition.
Be that according to the mode of execution of Fig. 3 and Fig. 4 and basic difference it does not comprise the yarn inserting member according to the mode of execution of Fig. 1 and Fig. 2.Only connect between driving element 112 and the drive element 114 by rubber layer 126 and metal tape 124.In addition, this mode of execution is with difference according to first mode of execution of Fig. 1 and Fig. 2, motion-stopping structure 140 and opposed motion-stopping structure 142 are not that certain engagement by as depicted in figs. 1 and 2 realizes, but realize by two polyhedrons (being corresponding mutually hexahedron here), these two polyhedral surface arrangement that are parallel to each other become to be spaced apart from each other, and rubber layer 126 is arranged in therebetween with metal tape 124.
But its mode of operation and the above mode of having described are similar.Here final arrival, also produces relative rotation, till can not produce further counterrotating most compressed state basically with progressive nature.
Layout according to Fig. 3 and Fig. 4 can be attached to axle equally upward to carry out vibration damping, for example is welded to two axle heads.
Adopt identical reference character to describe another mode of execution once more according to Fig. 5 and Fig. 6, but prefix number " 2 " in addition.In this embodiment, driving element 212 and drive element 214 overlap on bigger axial region 216.This axial region 216 can be divided into the first axial subregion 232 and the second axial subregion 234.In the first axial subregion 232, driving element 212 is cylindrical design with drive element 214.Their sizable intervals that is arranged to separate each other that is to say that they limit the annular space of relative broad each other.In this annular space, be equipped with two rubber layers 236 and 238 that driving element 212 are connected to drive element 214.
In the second axial subregion 234, the whole periphery of driving element 212 is designed to wave pattern, thereby forms motion-stopping structure 240.Equally, design has corresponding wave profile in the inner space of drive element 214, thereby forms opposed motion-stopping structure 242.It is complimentary to one another that motion-stopping structure 240 and opposed motion-stopping structure 242 are designed to, and that is to say, they engage one another in the mode that forms betwixt all the time around the midfeather of its extension.Fill this midfeather with rubber layer 244.
Axially subregion 232 forms pre-damper, and axially subregion 234 forms main damper.During operation, the pre-damper in the subregion 232 is at first reversed, and makes that driving element 212 can be around longitudinal axis A with respect to drive element 214 rotations when transmitting torque.Main damper has suitable rotation play for this reason.The rigidity of pre-damper is relatively low.When the play that provides in the main damper in the axial region 234 is used up, just can then produce further rotation relatively between driving element 212 and the drive element 214, at this moment pre-damper and the equal torsional deflection of main damper in the two axial subregions 232 and 234.Thereby, the same classification progressive nature that produces between the phase buffer of torsional vibration.
Should note, motion-stopping structure 240 and opposed motion-stopping structure 242 not only can be made by rolling forming in Fig. 5 and illustrative embodiments shown in Figure 6, and in illustrative embodiments described above and below the mode of execution that describes also can be made by rolling forming.

Be mainly that according to another mode of execution of Fig. 7 and Fig. 8 and difference main damper and pre-damper are not axially to arrange adjacent to each other, but these two dampers are arranged with the relation of axial overlap joint according to the mode of execution of Fig. 5 and Fig. 6.Thereby two axial region 232 and 234 can be accommodated in the quite little axial region 316.As can be seen, driving element 312 is designed to have a plurality of parts for this reason, that is, and and exterior part 344 and inner piece 346.These two parts weld together at reference character 348 places at their contact area.Exterior part 344 has motion-stopping structure 340, and inner piece 346 is a cylindrical design in axial region 316 substantially.Drive element 314 is embodied as foundry goods, and in Fig. 7 in its left end 330 place's appropriate structuring to be attached to universal joint.In axial region 316, drive element 314 has columnar substantially inner peripheral surface, and is provided with corresponding opposed motion-stopping structure 342 in outer regions.Two rubber body 336 of pre-as can be seen damper and 338 are arranged between the cylindrical shape inner peripheral surface of inner piece 346 and drive element 346.The rubber layer 344 of main damper is assemblied between motion-stopping structure 340 and the opposed motion-stopping structure 342.
This layout is worked as described in reference Fig. 5 and Fig. 6, that is to say, this layout shows the classification progressive nature during the buffering torsional vibration.
In case bump, when exceeding predetermined force, this layout also longitudinally the direction generation destructiveness of axis A collapse, thereby drive element 314 is pulled in the driving element 312 and disconnect by being connected that two rubber body 336 and 338 form, thereby also disconnect the connection of passing through rubber layer 344 formation.Thereby the length of transmission system can shorten in a controlled manner.
Adopt the reference character that uses in the above-mentioned illustrative embodiments to describe once more according to Fig. 9 and another illustrative embodiments of the present invention shown in Figure 10, but prefix number " 4 " in addition.
The special characteristic of present embodiment is that driving element 412 and drive element 414 are connected to each other by intermediary element 450.Driving element 412 also is provided with motion-stopping structure 440.Equally, intermediary element 450 is provided with the opposed motion-stopping structure 442 of the correspondence that is arranged in axial region 452.Form rubber layer 444 between driving element 412 and intermediary element 450, this rubber layer constitutes main damper.In axial subregion 454, intermediary element 450 is connected with metal insert 458 with the rubber layer 456 of drive element 414 by low rigidity.Should point out that in addition in axial subregion 460, intermediary element 450 is connected with drive element 414 in the mode that the edge circumferentially has play by toothed elements 462.
In case bump, also can collapse according to the device of Fig. 9 and Figure 10, driving element 412 all can be pushed in the intermediary element 450 by nested promotion to collapse mode with drive element 414 in this case.
What should mention in addition is as shown in figure 10, to realize motion-stopping structure 440 and opposed motion-stopping structure 442 by corresponding polyhedron surface once more.
It should be noted that at last the mode of execution according to Fig. 9 and Figure 10 is designed to be attached to cardan shaft by two ends 428 and 430 being welded to corresponding axle head.
Only be that according to the mode of execution of Figure 11 and Figure 12 and difference drive element 514 is designed to the connecting bolt of constant velocity universal joint according to the mode of execution of Fig. 9 and Figure 10.
Mainly be two aspects according to the mode of execution of Figure 13 and Figure 14 and difference according to the mode of execution of Fig. 9 and Figure 10.On the one hand, the end with drive element 614 is designed for being attached to universal joint.On the other hand, be furnished with rubber body 665 in axial region 660 in hollow drive element 614, this rubber body has perforation along axial direction and transverse to the direction of this axial direction.This rubber body 665 is used for the acoustics decoupling zero of the gearing noise at toothed elements 662 places.The gearing noise that produces because of the interaction of the mating surface of toothed elements 662 enters rubber body 665 as structureborne noise.Structureborne noise is refracted at the border surface place of the passage that extends along axial direction and transverse to the direction of this axial direction and reflects.This noise that causes producing is interfered and is decayed, thereby the intensity of gearing noise is weakened.
In mode of execution, not by pre-damper and main damper but utilize the rolling contact to realize the classification progressive nature according to Figure 15 and Figure 16.Torque transmitter 710 has driving element 712 and drive element 714.Drive element 714 is provided with interior toothed elements and is arranged in the tubulose driving element 712.Driving element 712 is connected to each other by rubber layer 726 with drive element 714, rubber layer 726 be formed in the annular midfeather between driving element and the drive element and sulfuration on driving element and drive element.Rolling touch roll 760 is embedded in the rubber layer 726.The touch roll of should noting rolling did not upwards directly prop up by rubber layer 726 in week.Or rather, on the both sides of roller 760, be filled with the crescent-shaped land 762 and 764 of air respectively along circumferential setting.

From the right side schematic representation of Figure 27 as can be seen, rubber components 1920a, 1930a complete filling midfeather 1920,1930.Yet these midfeathers 1920,1930 must be by complete filling.Emphasis only is that rubber components 1920a, 1930a are connected to intermediate member 1400 driving element 1100 and drive element 1200 respectively.Thereby, rubber components 1920a props up by intermediary element 1400 in the zone of midfeather 1920 in the mode of frictional engagement and props up by drive element 1200, and rubber components 1930a props up by intermediary element 1400 in the zone of midfeather 1930 in the mode of frictional engagement and props up by driving element 1100.In this embodiment, the hardness of rubber components 1930a is less than the hardness of rubber components 1920a.
If be attached to a spool last (not shown) with driving element 1100 this moment, then rotatablely moving of axle is passed to the hub (not shown) that is attached to drive element 1200 by means of this torque transmitter 1000.When transferring rotational motion, driving element 1100 is at first with respect to drive element 1200 motions.During this relative movement, rubber components 1930a is subjected to shearing (distortion), when bump 1300 bumps against intermediary element 1400 till.Simultaneously, rubber components 1920a is also sheared.Be significantly less than in the hardness (shear ability) of rubber components 1930a under the situation of hardness of rubber components 1920a, may occur in rubber components 1920a be subjected to fully shearing before bump 1300 just bump against the situation of intermediary element 1400.If 1300 of bumps lean on intermediary element 1400 at this moment, if and driving element 1100 and thereby bump 1300 further with respect to drive element 1200 rotations, then the shear rate of rubber components 1930a remains unchanged, that is, the shearing of rubber components 1930a " is freezed ".Till rubber components 1920a further is subjected to shearing when the end of H shape intermediary element 1400 bumps against retainer 1500.
Compare with mode of execution shown in Figure 27, torque transmitter 2000 shown in Figure 28 has essentially identical structure, and difference is that the axial width (thickness) of rubber components 2920a (corresponding with the rubber components 1920a of Figure 27) increases, and equates at this axial width (thickness) with rubber components 2930a (corresponding with the rubber components 1930a of Figure 27).By the width of change rubber components 2920a, and its cutting performance (shear resistant) is reduced.Therefore rubber components 2920a bears higher the reversing of corresponding rubber components 1920a (shearing) than Figure 27 during the rotatablely moving of driving element 2100 and intermediary element 2400.
Specifically select by hardness and their width (geometrical shape), can be in a controlled manner torque transmitter 1000,2000 be reversed the behavior intervention rubber components 1920a, 1930a, 2920a, 2930a.Because rubber components 1930a, 2930a determined the tendency of the twisting characteristic curve of null range, and this is walked important and influential persons and keeps straight as far as possible, therefore rubber components 1930a, 2930a are adopted soft relatively material, the twisting characteristic the when hardness of rubber components 1920a, 2920a has been determined than high rotation angle.By selecting the concrete hardness of rubber components 1920a, 2920a, can obtain the corresponding progressive tendency of twisting characteristic.
Compare with the above-mentioned mode of execution of Figure 27 and Figure 28, mode of execution shown in Figure 29 shows the intermediary element 3400 that is designed to form closed loop shape.Intermediary element 3400 has the bump 3420 that radially extends internally, and these bumps 3420 can engage with the bump that extends radially outward 3300 of driving element 3100.Therefore as can be seen from Figure 29, per two bumps 3420 of intermediary element 3400 are arranged in week upwards adjacent with a bump 3300 of driving element 3100.Bump 3300 be arranged to along week of driving element 3100 towards each other at a distance of angular distance uniformly.With reference to the schematic representation on Figure 29 right side, rubber components 3930a between intermediary element 3400 and driving element 3100, being equipped with in the mode of frictional engagement.The mode of execution of Figure 29 comprises three rubber components 3930a, and these three rubber components are assembled in three arc midfeathers 3930.Outer rubber parts 3920a designs for closed-loop shaped, and is contained in the closed tubular midfeather 3920 between drive element 3200 and the intermediary element 3400 in the mode of frictional engagement.
If driving element 3100 is with respect to drive element 3200 rotations, then two rubber components 3920a, 3930a are sheared.Bump 3,300 one bumps against bump 3420, and the shearing condition of rubber components 3930a will " freeze ".When driving element 3100 continued rotation, rubber components 3920a was further sheared this moment, thereby till when the shear resistance drive element 3200 that has overcome rubber components 3920a rotates.Here, also specifically select, and can intervene the behavior of reversing (characteristic) of torque transmitter 3000 in a controlled manner by hardness and their width (thickness) to rubber components 3920a, 3930a.
Compare with mode of execution shown in Figure 29, the mode of execution of Figure 30 has the intermediary element 4400 of closed design, this intermediary element 4400 can with driving element 4100a, 4100b interlocking engage.Driving element comprises that being designed to the outside is the inner element 4100a of tubular of being of hexahedron.The axial two ends of element 4100a are attached with ring seal element 4100b.Outer radial periphery face place at these elements 4100b has bump 4300, and these bumps 4300 are arranged to wait angular distance.Hexahedron shown in Figure 30 is used for installing more easily distolateral end member 4100b.Because the bump 4300 of driving element is along circumferentially equidistantly arranging with short relatively interval, therefore in the axial annular closed cavity 4920 that medially is arranged in torque transmitter 4400 of the rubber components 4930a quilt that driver part 4100 is connected in the frictional engagement mode with intermediary element 4400 (referring to the right side schematic representation of Figure 30).Rubber components 4920a is contained in the midfeather 4920 of the closed tubular design between drive element 4200 and the intermediary element 4400.
From the right side schematic representation of Figure 30 as can be seen, the width difference of rubber components 4920a, 4930a.In addition, rubber components 4920a is bigger with the frictional engagement surface of contact of intermediary element 4400 than rubber components 4930a with the frictional engagement surface of contact of intermediary element 4400.In mode of execution shown in Figure 30, the shear action of rubber components 4930a also determined the twisting characteristic curve tendency of null range, and the rubber components 4920a that designs than unfertile land relatively can form progressive twisting characteristic with higher angle of rotation.
