In addition, the same with common clutch, platen and cap assembly 3 are fixed by bolts on the flywheel 6, and release bearing and the separating mechanism 4 also clutch with common are the same, and release bearing 53 is bearing on the release sleeve 54, when depressing not shown clutch pedal (clutch operating device), withdrawal fork 55 promotes release sleeve 54 forward, release bearing 53 pushing diaphragm springs 56, and platen 7 moves backward, remove the impacting force of platen 7 and 6 pairs of friction plates 11 of flywheel, thereby make clutch 1 be in separated state.

And when unclamping not shown clutch pedal, release bearing and separating mechanism 4 move backward, and platen 7 is pressed on friction plate 11 on the flywheel 6, thereby clutch 1 is in jointing state.

As shown in Figure 1, slide fuel-economizing clutch 1 of the present invention is different with common clutch and increased the locking power connection set 5 except the structure of clutch drived disk assy 2, and total structural type and existing diaphragm spring clutch are roughly the same.

Below at first the 26S Proteasome Structure and Function of clutch drived disk assy 2 is described.

The detailed structure of clutch drived disk assy 2 mainly is made of friction plate 11, torsional vibration damper 60, free wheel device 21, jaw clutch 80, electromagnet 90 as shown in Figure 1, Figure 2, Figure 3 and Figure 4.

As shown in the figure, friction plate 11 is fixed on the both sides of wavy spring sheet 10 by rivet 12, be fixed on the driven steel disc 14b in back by close center one side of rivet 13 wavy spring sheet 10, preceding driven steel disc 14a and the driven steel disc 14b in back are connected rivet 15 and link into an integrated entity, and damping disk(-isc) 16 is clipped between forward and backward driven steel disc 14a, the 14b, close radial center one side between forward and backward driven steel disc 14a, 14b and damping disk(-isc) 16 is equipped with damping member 17,17.On the corresponding position of forward and backward driven steel disc 14a, 14b and damping disk(-isc) 16, offer a plurality of windows 18, helical spring 19 is installed in these windows 18.Because at transmitting torque or when meeting impulsive load, forward and backward driven steel disc 14a, 14b and damping disk(-isc) 16 are along circumferential compression helical spring 19, and rotate a certain angle relatively, therefore, as shown in Figure 7, offer a plurality of opening 20a of interfering with driven steel disc 14b and wavy spring 10 of being used to avoid in the outer rim (front cover 20 of free wheel device 21 described later) of damping disk(-isc) 16, and on damping disk(-isc) 16, offer the opening 16a of the space of promising connection rivet 15.In fact, forward and backward driven steel disc 14a, 14b, damping disk(-isc) 16, helical spring 19 and damping member 17,17 constitute torsional vibration dampers 60.The torsional vibration damper 60 of present embodiment 1 is also referred to as the helical spring coupling sometimes.

In present embodiment 1, forward and backward driven steel disc 14a, 14b are the input ends of torsional vibration damper 60, and damping disk(-isc) 16 is output terminals of torsional vibration damper 60.Friction plate 11 is connected with input end 14a, the 14b of torsional vibration damper 60 by wavy spring sheet 10.The clutch drived disk assy of above structural type and existing clutch is roughly the same.

In Fig. 2, free wheel device 21 is friction roll pillar free wheel devicees, mainly is made of front cover 20, shell 23, rear end cover 24, roller 25 and star-wheel 26.As shown in the figure, the outer rim of damping disk(-isc) 16 and front cover 20 are one, and link into an integrated entity with rivet 22 and shell 23, rear end cover 24.On shell 23 and rear end cover 24, be provided with and be used to prevent roller 25 axially movable lip part 23a and 24a.The hub portion 31 of star-wheel 26 be provided with internal spline 8a interior week, as shown in Figure 1, internal spline 8a is connected with the external splines 8 of transmission input shaft 9, and free wheel device 21 is bearing on the transmission input shaft 9.In addition, in the periphery of the hub portion 31 of star-wheel 26 bearing 30 is installed, the hub portion 32 of damping disk(-isc) 16 is bearing on the bearing 30, by circlip 76 and 77 rigid bearings 30.Because the shell 23 of free wheel device 21 links into an integrated entity with damping disk(-isc) 16, thus shell 23 can be relative together with damping disk(-isc) 16 star-wheel 26 rotate freely around axis.

The main structure form of free wheel device 21 of the present invention is provided with a plurality of planes 27 and facade 28 in the outer rim of star-wheel 26 as shown in Figure 5 and Figure 6, and roller 25 is installed between the plane 27 and facade 28 of the inner circle wall 58 of shell 23 and star-wheel 26.

Though the friction roll pillar free wheel device that textbook or design handbook are introduced, all be provided with and claim that being used to revolt centrifugal force pushes roller 25 to the inner peripheral surface 58 of shell 23 and the ejector pin and the spring in the 27 formed bights, plane of star-wheel 26, but the inventor thinks, during free wheel device 21 rotations, roller 25 also rotates around axis, so roller 25 suffered centrifugal force are radially outside, so roller 25 is because action of centrifugal force, directly be pressed on the inner circle wall 58 of shell 23, in the rotation speed n of shell 23 ₁Rotation speed n greater than star-wheel 26 ₂The time, because the inner circle wall 58 of shell 23 and the frictional force between the roller 25, shell 23 can be with the plane 27 formed bights of roller 25 bands to inner peripheral surface 58 with the star-wheel 26 of shell 23.And, less for the volume that makes free wheel device 21, or for roller 25 is set, the ejector pin and the spring of pushing roller 25 is not set preferably more.This is a notable feature of free wheel device 21 of the present invention.

At present embodiment 1, shell 23 is input ends of free wheel device 21, and star-wheel 26 is defeated middle-ends.Therefore, at present embodiment 1, a part of structural type of clutch drived disk assy 2 is: friction plate 11 is connected with the input end (forward and backward driven steel disc 14a, 14b) of torsional vibration damper 60, the output terminal of torsional vibration damper 60 (damping disk(-isc) 16) is connected with the input end (shell 23) of free wheel device 21, and the output terminal of free wheel device 21 (star-wheel 26) is connected with transmission input shaft 9.

Below the effect and the motion conditions of free wheel device 21 each part described.

As Fig. 1, Fig. 2, Fig. 5 and shown in Figure 6, when clutch 1 is in jointing state, rotatablely moving of engine crankshaft 57, be delivered to the input end of torsional vibration damper 60 by friction plate 11 and wavy spring sheet 10, be delivered to input end---the shell 23 of free wheel device again by the output terminal of torsional vibration damper 60.Rotation speed n when shell 23 ₁Rotation speed n greater than (temporarily) star-wheel 26 ₂The time, because roller 25 is around the rotation of the center of star-wheel 26, has centrifugal force towards the inner circle wall 58 of shell 23, so be pressed on the inner circle wall 58 of shell 23, roller 25 because and the frictional force between shell 23 inner circle walls 58, and along circumferentially rolling to directions X, and roller 25 is clipped between the plane 27 of the inner circle wall 58 of shell 23 and star-wheel 26 outer rims, because angle α/2 are less than the friction angle of steel and steel, so, roller 25 can be clamped between inner circle wall 58 and the plane 27, can not deviate from, thereby make star-wheel 26 with the rotating speed rotation identical with shell 23.

As shown in Figure 1, because the internal spline 8a in week is connected with the external splines 8 of transmission input shaft 9 in the star-wheel 26 hub portions 31, so, this moment, rotatablely moving of engine crankshaft 57 was delivered to transmission input shaft 9 by friction plate 11, torsional vibration damper 60, free wheel device 21, and engine crankshaft 57 rotates synchronously with transmission input shaft 9.

And when the rotation speed n of shell 23 ₁Rotation speed n less than star-wheel 26 ₂(n ₁＜n ₂) time, because the frictional force between shell 23 inner circle walls 58 and the roller 25, roller 25 is along circumferentially rolling to the Y direction, and rest between the facade 28 of the inner circle wall 58 of shell 23 and star-wheel 26 outer rims (the double dot dash line position of Fig. 6), at this moment, because angle β/2 are greater than the friction angle of steel and steel, and has gap H between the plane 27 of the outer circumferential face of roller 25 and star-wheel 26 outer rims, so, roller 25 can not be clamped between the facade 28 of the inner circle wall 58 of shell 23 and star-wheel 26 outer rims, so star-wheel 26 and shell 23 relative rotations.

As depicted in figs. 1 and 2, because the internal spline 8a in week is connected with the external splines 8 of transmission input shaft 9 in the hub portion 31 of star-wheel 26, so, the rotating speed (n of star-wheel 26 ₂) identical with the rotating speed of transmission input shaft 9, because the rotating speed (n of shell 23 ₁) identical with the rotating speed of engine crankshaft 57, so, after vehicle has been installed slide fuel-economizing clutch 1 of the present invention, if the rotating speed (n of shell 23 ₁) less than the rotating speed (n of star-wheel 26 ₂), then star-wheel 26 can rotate relatively with shell 23.So, in the rotation speed n of engine crankshaft 57 ₁Less than the rotation speed n that is delivered to transmission input shaft 9 from wheel ₂The time, transmission input shaft 9 engine crankshaft 57 rotations relatively.That is to say, when vehicle had certain speed, if make the rotating ratio of engine crankshaft 57 low from the rotating speed that wheel is delivered to transmission input shaft 9, then motor was not to transmission input shaft 9 transmitting torques, and vehicle is not braked, vehicle can continue to slide at a high speed by inertia.

As previously discussed, owing to work as the rotating speed (n of the shell 23 of free wheel device 21 ₁) greater than the rotating speed (n of (temporarily) star-wheel 26 ₂) time, roller 25 can be sandwiched between the plane 27 of the inner circle wall 58 of shell 23 and star-wheel 26 outer rims, shell 23 and star-wheel 26 rotate synchronously, so, when the rotating speed that temporarily makes engine crankshaft 57 when being delivered to the rotating speed of transmission input shaft 9 from wheel, free wheel device 21 can be from input end (shell 23) to output terminal (star-wheel 26) transmitting torque, and engine crankshaft 57 rotates synchronously with transmission input shaft 9, and motor is to gear-box output torque.That is to say, when improving engine speed, can use motor-powered vehicle, vehicle is given it the gun.

As previously discussed, owing to after vehicle has certain speed, can make motor be in idling mode, and vehicle can launched mechanism not move, and vehicle can continue to slide at a high speed by inertia, because vehicle can slide very long distance, oil consumption is very little during engine idle, so can save considerable fuel oil.And, when needs drive vehicle with motor, as long as the raising engine speed of stepping on the throttle just can make vehicle quicken,

In addition, as depicted in figs. 1 and 2,, be provided with jaw clutch 80 in the axial rear end of free wheel device 21.This jaw clutch 80 is mainly by non axial movable part---fixed gear ring 81, axial movable part---, and movable fluted disc 82, ejector pin 83, spring 84 and stop screw 85 constitute.

As Fig. 2, Fig. 8 and shown in Figure 9, in fact fixed gear ring 81 is exactly the rear end cover 24 of free wheel device 21, circumferentially be formed with triangle tooth 81a on its rearward end edge near radial center one side, corresponding with it, circumferentially be formed with triangle tooth 82a on the front end edge of movable fluted disc 82 radial outsides.The triangle tooth 81a that makes on the fixed gear ring 81 can be meshing with each other with the triangle tooth 82a on the movable fluted disc 82.

In addition, be formed with a plurality of holes 39 on the center of star-wheel 26 ring portion 38, spring 84 and ejector pin 83 are inserted in the hole 39, and the rearward end of ejector pin 83 is against on the front-end face of movable fluted disc 82.Therefore, because the effect of spring 84, movable fluted disc 82 has the trend to direction (rearward) motion of opening (release) jaw clutch 80 all the time.In addition, the interior week in the hub portion 88 of movable fluted disc 82, be formed with internal spline 8b, as shown in Figure 1, under with clutch drived disk assy 2 vehicle-mounted states, internal spline 8b is connected with the external splines 8 of transmission input shaft 9, and movable fluted disc 82 can slide vertically freely.In addition, aim at the spline tooth of the internal spline 8a of star-wheel 26 for the spline tooth that the time can make the internal spline 8b of movable fluted disc 82 in assembling, thereby can successfully insert the external splines 8 of transmission input shaft 9, disc at movable fluted disc 82 partly is provided with circumferentially microscler through hole 86 (its angle of circumference is greater than 360 °/z, and z is a spline tooth number) of a plurality of edges.A plurality of stop screws 85 pass through hole 86 but do not pass baffle plate 40 and are fixed on the center ring portion 38 of star-wheel 26, limit the distance that activity fluted disc 82 rearward moves by the head of stop screw 85, prevent that by baffle plate 40 coil 68 from rearward deviating from simultaneously.

Because fixed gear ring 81 is exactly the rear end cover 24 of free wheel device 21, and link into an integrated entity with the shell 23 of free wheel device 21, and movable fluted disc 82 is connected with the external splines 8 of transmission input shaft 9, and the star-wheel 26 of free wheel device 21 also is connected with the external splines 8 of transmission input shaft 9, just movable fluted disc 82 can endwisely slip and can not be connected with the star-wheel 26 of free wheel device 21 with relatively rotating, so the star-wheel 26 of movable fluted disc 82 and free wheel device 21 rotates synchronously.Therefore,---fixed gear ring 81, axial movable part---jaw clutch 80 that movable fluted disc 82, ejector pin 83, spring 84 and stop screw 85 constitute by non axial movable part, be arranged between the input end (shell 23) of free wheel device 21 and the output terminal (star-wheel 26), that is to say that jaw clutch 80 is blocking devices of free wheel device 21.

In addition, in fact also can adopt non axial movable part to be connected with the output terminal (star-wheel 26) of free wheel device 21, axially movable part can endwisely slip and the structural type that can not be connected with the input end (shell 23) of free wheel device 21 with relatively rotating.

In addition, as Fig. 2 and shown in Figure 5, between the radial outside of the radially inner side of star-wheel 26 outer edges 70 and center ring portion 38, be formed with circular groove 67, electromagnetic coil 68 is embedded in this circular groove 67.In addition, interior all sides at electromagnetic coil 68 are formed with projection (figure does not show), circular groove 67 1 sides in center ring portion 38 are formed with groove (figure does not show), when being embedded into electromagnetic coil 68 in the circular groove 67, the projection of electromagnetic coil 68 is stuck in the groove of center ring portion 38, is used for preventing that electromagnetic coil 68 from rotating along circumferential at circular groove 67.Like this, constitute the yoke of electromagnet 90 by outer edge 70, disc portion 69 and the center ring portion 38 of star-wheel 26, the axial movable part of jaw clutch 80---movable fluted disc 82 is the armature of electromagnet 90.Therefore constitute electromagnet 90 by outer edge 70, disc portion 69 and the center ring portion 38 of star-wheel 26 and coil 68, movable fluted disc 82.Because after giving electromagnetic coil 68 energisings, this electromagnet 90 produces electromagnetic attraction, making the axial movable part of jaw clutch 80---movable fluted disc 82 (armature) moves forward vertically, jaw clutch 80 lockings, so, the locking executive component that this electromagnet 90 is jaw clutches 80.

More than explanation, a notable feature of the present invention, be exactly that blocking device (jaw clutch 80) comprises non axial movable part (fixed gear ring 81) and axial movable part (movable fluted disc 82), non axial movable part (fixed gear ring 81) is connected with the input end (shell 23) or the output terminal (star-wheel 26) of free wheel device 21, axially movable part (movable fluted disc 82) can endwisely slip and can not be connected that (at present embodiment 1 is by 8 realizations of the external splines on the transmission input shaft 9 with relatively rotating with the output terminal (star-wheel 26) or the input end (shell 23) of free wheel device 21, spline also can be set on star-wheel 26 and movable fluted disc 82 to be realized), locking executive component (electromagnet 90) comprises yoke, electromagnetic coil 68 and armature, electromagnetic coil 68 is embedded in the yoke, and yoke and armature are arranged between the axial movable part (movable fluted disc 82) of free wheel device 21 and blocking device (jaw clutch 80).

When giving electromagnetic coil 68 energisings, the outer edge 70 of the yoke part of electromagnet 90---star-wheel 21, disc portion 69 and center ring portion 38, armature part with electromagnet 90---movable fluted disc 82 forms closed magnetic circuit, the rearward end of the close movable fluted disc 82 of outer edge 70 and center ring portion 38 produces electromagnetic attraction, the spring force that makes movable fluted disc 82 overcome spring 84 moves to the direction (forwards) that jaw clutch 80 engages (locking), and triangle tooth 81a on the fixed gear ring 81 and the triangle tooth 82a on the movable fluted disc 82 are meshing with each other.At this moment, the shell 23 of free wheel device 21 rotates synchronously with star-wheel 26.When jaw clutch 80 engages, can make from the torque of motor input end (forward and backward driven steel disc 14a, 14b), the output terminal (damping disk(-isc) 16) of torsional vibration damper 60, the rear end cover 24 (with front cover 20, shell 23 one) of free wheel device 21, movable fluted disc 82 through engine flywheel 6, friction plate 11, wavy spring 10, torsional vibration damper 60, be directly delivered to transmission input shaft 9, in other words, the load of vehicle can be directly reflected on the motor by the jaw clutch 80 of this locking.That is to say, when blocking device (jaw clutch 80) locking (joint), can brake vehicle with motor.

Shown in Figure 10 is the longitudinal sectional view of the clutch drived disk assy 2 when engaging jaw clutch 80.As shown in the figure, when giving electromagnetic coil 68 energisings, jaw clutch 80 engages.Under this state, leave air gap (gap) δ between the rearward end of the outer edge 70 of star-wheel 26 and center ring portion 38 (yoke) and the movable fluted disc 82 (armature).In addition, in order not make the magnetic circuit short circuit, the rearward end of the hub portion 31 of the front end of the hub portion 88 of movable fluted disc 82 and star-wheel 26 axially between, and the center ring portion 38 of the hub portion 88 of movable fluted disc 82 and star-wheel 26 radially between, leave bigger gap.This also illustrates, the hub portion 88 of movable fluted disc 82 can not be subjected to the axial force backward from star-wheel 26 hub portions 31, so 90 of electromagnet tight that give birth to, act on forward the electromagnetic attraction vertically on the movable fluted disc 82, fully act on backward thrust institute balance (comparatively speaking, the thrust of spring 84 is less) vertically on the triangle tooth 82a of movable fluted disc 82 by the triangle tooth 81a of fixed gear ring 81.So, as its counter-force, the triangle tooth 82a of movable fluted disc 82 acts on forward the power vertically on the triangle tooth 81a of fixed gear ring 81, size equates with this electromagnetic attraction, this is forward power vertically, by rear end cover 24, shell 23, front cover 20, damping disk(-isc) 16, act directly on the outer ring of bearing 30.That is to say that the foreign country of bearing 30 is subjected to direction power forward.In addition, because the outer edge 70 of star-wheel 26 and the rearward end attraction activity fluted disc 82 of center ring portion 38, so, as its counter-force, outer edge 70 and center ring portion 38 are subjected to direction power backward, because the effect of circlip 77, the inner ring of bearing 30 is subjected to direction power backward.And the size of these power all equals electromagnetic attraction, so the suffered power opposite sign but equal magnitude of the outer ring of bearing 30 and inner ring.

Like this, owing to engage (locking) jaw clutch 80 needed impacting forces, be the internal force in the clutch drived disk assy 2, whole clutch drived disk assy 2 is not subjected to direction external force forward or backward, so, even clutch drived disk assy 2 under the situation of blocking device (jaw clutch 80) locking (joint), also can be the same with existing clutch driven disc assembly, on transmission input shaft 9, slide freely, the halfway phenomenon of clutch separation can not occur.

And when electromagnetic coil 68 outages, the electromagnetic attraction of the outer edge 70 of star- wheel 26 and 38 pairs of movable fluted discs 82 of center ring portion disappears, and movable fluted disc 82 rearward moves under the effect of spring 84, the fixed gear ring 81 of jaw clutch 80 separates the unlocking state with movable fluted disc 82.And this moment, clutch drived disk assy 2 each part only had the axial spring force that effect has spring 84 to be produced between star-wheel 26 and the movable fluted disc 82, and the head institute balance of the limited screw 85 of this axial force, internal force for clutch drived disk assy 2, because clutch drived disk assy 2 is not subjected to outside axial force, so, still can on transmission input shaft 9, slide freely, the halfway phenomenon of clutch separation can not occur.

That is to say, because will make jaw clutch 80 (blocking device) engage the yoke of electromagnet 90 (locking executive component) of (locking) and armature is arranged on free wheel device 21 (at present embodiment 1 is that yoke or armature are arranged on the star-wheel 26, but also yoke or armature can be arranged on the shell 23 in theory) and the movable fluted disc 82 of jaw clutch 80 (blocking device) (axially movable part) between, so engage the needed impacting force of (locking) jaw clutch 80 (blocking device), be the internal force in the clutch drived disk assy 2, therefore, no matter whether jaw clutch 80 (blocking device) engages (locking), clutch drived disk assy 2 can both slide on transmission input shaft 9 freely, the halfway phenomenon of clutch separation can not occur.

Below the electrical connection arrangement 5 of the embodiment of the invention 1 is described.

Figure 11 (a) is the longitudinal sectional view of carbon brush holder assembly 71, Figure 11 (b) is the sectional view of the carbon brush holder assembly 71 that dissects of the A-A line along Figure 11 (a), Figure 12 is the longitudinal sectional view of slip ring assembly 29 (supporting sleeve 50), and Figure 13 is the figure that is illustrated in carbon brush 73 and the position relation of slip ring 96 under the situation that jaw clutch 80 engages.

As Fig. 1, Fig. 2, Fig. 4 and shown in Figure 11, carbon brush holder assembly 71 usefulness screws 91 are fixed on the movable fluted disc 82 (armature of electromagnet 90).Carbon brush holder assembly 71 mainly is made of carbon brush holder body and lid 72, carbon brush 73, carbon brush holder 74, holder Returnning spring 75 and carbon brush holddown spring 78.The place ahead of close radial center one side of carbon brush 73 is provided with breach 79.Carbon brush 73 is installed among the carbon brush groove 72b, by being fixed on the carbon brush holder body and the carbon brush holddown spring 78 of lid on 72 compresses, makes it have the trend that moves to center radially all the time.Bearing pin 92 is installed on carbon brush holder body and the lid 72, and carbon brush holder 74 and holder Returnning spring 75 are installed on the bearing pin 92, and carbon brush holder 74 can be around bearing pin 92 rotations.Close radial center one side of carbon brush holder 74 has prominent protuberance 93 to carbon brush 73 1 sides and prominent to the protuberance 94 at center radially.Constitute the carbon brush retaining mechanism by breach 79 of carbon brush holder 74, holder Returnning spring 75 and carbon brush 73 etc., protuberance 93 is a protective gear.Because the effect of holder Returnning spring 75, carbon brush holder 74 have around bearing pin 92 rotations, make protuberance 93 be stuck in trend in the breach 79 of carbon brush 73.And, under protuberance 93 is stuck in state in the breach 79 of carbon brush 73, the diameter of the working surface 73a position of carbon brush 73 radially inner sides, external diameter than the slip ring 96 of slip ring assembly 29 described later (supporting sleeve 50) front end is big, and carbon brush holder 74 is prominent to the diameter of protuberance 94 positions at center radially, external diameter than the slip ring 96 of slip ring assembly 29 front ends is little, and in close motor one side of carbon brush 73.When direction external force forward acts on the protuberance 94, carbon brush holder 74 overcomes the spring force of holder Returnning spring 75, around bearing pin 92 rotation, make protuberance 93 break away from the breach 79 of carbon brush 73, carbon brush 73 moves to center radially under the effect of carbon brush holddown spring 78.

As Fig. 2, Fig. 9 and shown in Figure 11, when assembling clutch drived disk assy 2, one end and the star-wheel 26 of electromagnetic coil 68 leads are electrically connected (ground connection, figure does not show), the other end of lead passes the through hole 82b on the movable fluted disc 82, pass again and be arranged on carbon brush holder body and the through hole 72a of lid on 72, be electrically connected (figure does not show) with the lead-in wire of carbon brush 73.If for static balancing, a plurality of (among the figure being 3) carbon brush 73 is set in carbon brush holder assembly 71, then a plurality of carbon brush 73 parallel connections, reducing under the situation of high engine speeds rotation, because of centrifugal force or the supporting sleeve 50 eccentric carbon brush that produce 73 break away from the phenomenon that slip ring 96 described later, electromagnetic coil 68 cut off the power supply.

In fact carbon brush holder assembly 71 and movable fluted disc 82 (armature of electromagnet 90) can be made one, to reduce the axial dimension of clutch drived disk assy 2.But because carbon brush holder assembly 71 is easily damaged parts (especially carbon brush 73 and carbon brush holders 74), in order to change convenient and to reduce the expense of changing easily damaged parts, the structural type of carbon brush holder assembly 71 and movable fluted disc 82 being made split is comparatively desirable.

At present embodiment 1, for electric power being incorporated into the inside of platen and cap assembly 3, utilize the body of supporting sleeve 50 as slip ring assembly 29, for the clutch that does not have supporting sleeve, just the slip ring supporting mass need be set.As shown in figure 12, slip ring assembly 29 is fixed with a fittings body 95 at the front end of slip ring supporting body 50a by bonding or other technology, is fixed with slip ring 96 in front end periphery, the centre of this fittings body 95 across isolation layer 97.On slip ring supporting body 50a and fittings body 95 and isolation layer 97, be provided with axial bore 98, lead 99 is arranged in the axial bore 98 and (also can axial groove be set at internal surface or the outer surface that slip ring supports body 50a, lead 99 is embedded in the axial groove, and use adhesive securement), one end of lead 99 is electrically connected with slip ring 97 in axial bore 98 inside, the other end passes the hole 50b that is arranged on slip ring assembly 29 base end parts and draws, be electrically connected with the interlocking control device that is arranged on operator cabin (switch or controller, figure does not show).
