The present invention includes a kind of infinitely variable speed transmission, its use that can combine with the machinery of any kind that needs transmission device.For example, transmission device can be used for (i) motor-driven vehicle such as automobile, motorcycle, or boats and ships, (ii) non-maneuverable vehicle such as bicycle, tricycle, foot plate bicycle, exercise device or (iii) industry equipment such as drilling machine, power equipment, or loom.
With reference to Fig. 1 and 2, a kind of infinitely variable speed transmission 100 is disclosed.Transmission device 100 is coated in the hub shell 40 that is covered by hub cap 67.At the center of transmission device 100 is three or more power adjustment device 1a, 1b and 1c, and they are spherical and center line or rotatingshaft uniformly-spaced center on transmission device 100 along periphery.As being seen by more obvious among Fig. 2, axle 3a, 3b and 3c inserted the center of power adjustment device 1a, 1b and 1c and limited the rotatingshaft of power adjustment device 1a, 1b and 1c.In Fig. 1, the rotatingshaft of power adjustment device is shown in substantially horizontal.Axle supporting member 2a-2f vertically is connected in and is connected each exposed junction of axle 3a, 3b and 3c.In one embodiment, each axle supporting member has a hole to admit one of them a end of axle 3a, 3b and 3c.Axle 3a, 3b and 3c also have axle roller 4a-4f, and its outside at axle supporting member 2a-2f coaxially and slidably is positioned on the exposed junction of axle 3a, 3b and 3c.
When making the oblique in-migration of axle 3a, 3b and 3c change the rotatingshaft of power adjustment device 1a, 1b and 1c, each of axle roller 4a-4f is moving along the groove 6a-6f that cuts out in fixed support 5a, 5b.With reference to Fig. 1 and 3, fixed support 5a, 5b are essentially the form of parallel discs, have along the rotation axis of the center line of transmission device 100.Groove 6a-6f extends to the centerline direction of transmission device 100 from the outer periphery of fixed support 5a, 5b.Though the side of groove 6a-6f is parallel basically, the bottom surface of groove 6a-6f forms radius decrescence when its centerline direction to transmission device 100 extends.When the rotatingshaft by changing power adjustment device 1a, 1b and 1c transforms to one during than bottom gear or higher speed shelves with transmission device 100, the every center roller roller 4a-4f that is positioned on a single axle 3a, 3b and the 3c moves in the opposite direction along their respective groove 6a-6f.
With reference to Fig. 1 and 3, center hole 7a, the 7b among fixed support 5a, the 5b can make a hollow shaft 10 insert fixed support 5a, 5b.With reference to Fig. 4, in one embodiment of the invention, one or more fixed support hole 7a, 7b can have non-cylindrical shape 14, its be fitted into one on the corresponding non-cylindrical body 15 of hollow shaft 10 to prevent any the relatively rotating between fixed support 5a, 5b and the hollow shaft 10.If the insufficient rigidity of fixed support 5a, 5b can adopt additional structure to make any relatively rotate or the bending of fixed support 5a, 5b reduces to minimum.This type games of fixed support 5a, 5b can cause the constraint to the axle roller 4a-4f when groove 6a-6f moves.
As shown in Fig. 4 and 7, additional structure can take to be connected separator 8a, 8b between fixed support 5a, the 5b and the form of 8c.Separator 8a, 8b and 8c increase the rigidity between fixed support 5a, the 5b, and in one embodiment, are positioned at the vicinity, outer periphery of fixed support 5a, 5b.In one embodiment, fixed support 5a, 5b are connected in separator 8a, 8b and 8c by means of the bolt of inserting the hole 46a-46f among fixed support 5a, the 5b or other securing meanss 45a-45f.
Refer again to Fig. 1 and 3, fixed support 5a is fixedly connected to fixed support cover 42, the wall that it coaxially centers on hollow shaft 10 and extends through hub shell 40.Fixed support cover 42 ends that extend through hub shell 40 are connected in the frame supporting member and preferably have non-cylindrical shape to strengthen the connection subsequently of a torque rod 43.As illustrating more significantly among Fig. 7, torque rod 43 is placed on the end of non-cylindrical of fixed support cover 42 and is held in place with a torque nut 44.Torque rod 43 is rigidly connected at its other end on the motionless parts of the last one, for example (not shown) on the framework.One fixed support bearing, 48 supporting hub shells 40 and hub shell 40 is rotated with respect to fixed support cover 42.
Refer again to Fig. 1 and 2, gear shift comes manual control by the bar 11 that is positioned in the hollow shaft 10 that endwisely slips.One or more is sold one or more transverse holes in 12 insertion rods 11 and also extends through one or more cannelure 16 (not shown) in the hollow shaft 10.Groove 16 in the hollow shaft 10 can make pin 12 and bar 11 assemblies axially move in hollow shaft 10.When bar 11 axially slided in hollow shaft 10, each end of transverse bolt 12 stretched into and is connected in coaxial cover 19.This cover 19 is fixedly connected to platform 13a, a 13b who is essentially the plane at its each end, and this platform 13a, 13b form a groove around the periphery of cover 19.
As by seeing more significantly among Fig. 4, surface platform 13a, 13b all contact and promote a plurality of 21a-21f of wheel.Be held in place in the groove among the wheel 21a-21f threading axle supporting member 2a-2f and by wheel shaft 22a-22f.Wheel shaft 22a-22f also can make wheel 21a-21f rotate in their each end by axle supporting member 2a-2f supporting.
Refer again to Fig. 1 and 2, be essentially platform 13a, the 13b on plane and change a convex surfaces in their outer circumference (from hollow shaft 10 farthest).The gap can be making transmission device 100 gear shift be removed in this zone when axle supporting member 2a-2f and power adjustment device 1a, 1b and 1c tiltedly move.Thereby a cylindrical support member 18 is located in the groove that forms between surface platform 13a, 13b and the cover 19 and with surface platform 13a, 13b and cover 19 consistent moving.Support member 18 bridges on contact bearing 17a, the 17b at the crosspoint place that is positioned at surface platform 13a, 13b and cover 19 so that support member 18 freely rotates around the axis of transmission device 100.Therefore, when making transmission device 100 gear shift, bearing 17a, 17b, support member 18 and cover 19 all endwisely slip with surface platform 13a, 13b.
Referring now to Fig. 3 and 4, the roller 30a-30l of fixed support is connected in each axle leg 2a-2f in pairs by roller pin 31a-31f and upward and with roller folder 32a-32l is held in place.Roller pin 31a-31f can make the roller 30a-30l of fixed support freely rotate around roller pin 31a-31f.The concavity radius upper edge one of the roller 30a-30l of fixed support in fixed support 5a, 5b is arranged essentially parallel to the path of groove 6a-6f and rolls.When axle roller 4a-4f moves forward and backward in groove 6a-6f, the roller 30a-301 of fixed support neither allows each end of axle 3a, 3b and 3c not allow the bottom surface of axle roller 4a-4f contact trench 6a-6f again, so that keep the position of axle 3a, 3b and 3c and make any frictional loss reduce to minimum.
Fig. 4 illustrates roller 30a-30l, roller pin 31a-31f and the roller folder 32a-32l of fixed support, for ease of observing, as being found out by fixed support 5a.For clarity sake, a lot of labels of the roller 30a-30l of the fixed support among Fig. 1, roller pin 31a-31f and roller folder 32a-32l do not mark in Fig. 1.
Be adjacent to fixed support 5b location with reference to Fig. 1 and 5, one concavity drive plates 34, partly encapsulate fixed support 5b but be not in contact with it.Drive plate 34 is rigidly connected on the threaded piece 35 by its center.Threaded piece 35 is local coaxial in hollow shaft 10 and form a cover around hollow shaft 10 what be adjacent to fixed support 5b, and in the face of a driving component 69.Drive plate 34 is rotationally coupled on power adjustment device 1a, 1b and the 1c along the periphery supporting surface on the lip of drive plate 34.One nut 37 is screwed on the threaded piece 35 and around its periphery and is rigidly connected on the bearing dish 60.A face of nut 37 also is connected in driving component 69.Be rigidly connected to equally bearing dish 60 the surface also have a plurality of sloping platforms 61, it is in the face of drive plate 34.Each sloping platform 61 is provided with a sloping platform bearing 62, remains on the appropriate location by a bearing cage 63.Sloping platform bearing 62 contact sloping platform 61 and drive plates 34.One spring 65 is connected in bearing cage 63 and is connected in drive plate 34 at its other end at the one end, or is connected in bearing dish 60 in another embodiment, so that sloping platform bearing 62 is biased on the sloping platform 61.Bearing dish 60 contacts a hub cap bearing 66 at it in contrast to a side of sloping platform 61 and on roughly same periphery.Hub cap bearing 66 contact hub caps 67 and bearing dish 60 are so that they can relative movement.Hub cap 67 usefulness are threaded onto on the hub shell 40 or are pressed into hub shell 40, and fixing with an inner ring 68.One sprocket wheel or belt wheel 38 are rigidly connected to the driving component 69 of rotation and externally are held in place by conical bearings 70 of fixing with tapered cup nut 71, with be held in place wherein driving bearing 72 contact driving component 69 and hub caps 67 by a driving bearing 72 in inside.
During operation, rotate from an input that is fixedly connected to sprocket wheel on the driving component 69 or belt wheel 38 and bearing dish 60 and a plurality of sloping platform 61 to be rotated and sloping platform bearing 62 is rolled on sloping platform 61, and drive plate 34 is pressed against on power adjustment device 1a, 1b and the 1c.Simultaneously, nut 37 rotates and makes threaded piece 35 and nut 37 combinations, and wherein the helical pitch of nut 37 is less than sloping platform 61.This structure has provided the rotation that presses against the drive plate 34 on power adjustment device 1a, 1b and the 1c.Power adjustment device 1a, 1b contact hub shell 40 and make its rotation when rotating with 1c.
When transmission device 100 inertia moved, sprocket wheel or belt wheel 38 stopped operating and hub shell 40 and power adjustment device 1a, 1b and 1c are rotated further.This causes drive plate 34 to rotate and makes threaded piece 35 precession nuts 37, till drive plate 34 no longer contacts power adjustment device 1a, 1b and 1c.
With reference to Fig. 1,6 and 7, and the coaxial helical spring 80 of transmission device 100 is being connected on bearing dish 60 and the drive plate 34 at each end of helical spring 80 between bearing dish 60 and the drive plate 34 and by means of pin or other fastening piece (not shown).In the operating process of transmission device 100, helical spring 80 is guaranteed contacting between power adjustment device 1a, 1b and 1c and the drive plate 34.One ratchet support 83 cooperates helical spring 80, and this helical spring is connected in ratchet support 83 with its middle spiral by means of pin or standard fasteners (not shown).Because ratchet support 83 is connected in the middle spiral of helical spring 80, its half speed with drive plate 34 is not rotated when bearing dish 60 does not rotate.This can make one or more locking pawl 81a, 81b and 81c engages drive dish ratchet 82, wherein each locking pawl 81a, 81b and 81c sell 84a, 84b by means of one or more and 84c is connected in ratchet support 83, and ratchet 82 is coaxial and is rigidly connected to drive plate 34 with drive plate 34.One or more locking pawl 84a, 84b and 84c are preferably asymmetric spaced apart around drive plate ratchet 82.In case engage, stop the helical spring 80 of stand under load that drive plate 34 is pressed against on power adjustment device 1a, 1b and the 1c.Therefore, because drive plate 34 does not contact with 1c with power adjustment device 1a, 1b, transmission device 100 is in neutral gear and has improved the simplification of gear shift.Transmission device 100 also can gear shift in operation.
When making transmission device 100 resume operations by rotating sprocket or belt wheel 38, one or more discharges ratchet 85a, 85b and 85c and contacts with relative bearing dish ratchet 87, and this release ratchet 85a, 85b and 85c all are connected among locking pawl 81a, 81b and the 81c one by means of a detent pin 88a, 88b and 88c.Bearing dish ratchet 87 is coaxial and is rigidly connected to bearing dish 60 with bearing dish 60.Be connected in ratchet support 83 owing to discharge ratchet 85a, 85b and 85c via locking pawl 81a, 81b and 81c, bearing dish ratchet 87 activates and discharges ratchet 85a, 85b and 85c.During operation, discharging ratchet 85a, 85b and 85c rotates with a half speed of bearing dish 60, because drive plate 34 does not rotate, and throw off locking pawl 81a, 81b and 81c and helical spring 80 is revolved drive plate 34 lean against on power adjustment device 1a, 1b and the 1c from drive plate ratchet 82.One or more ratchet tension device (not shown), each discharges ratchet 85a, 85b and 85c goes up with one, guarantees to make locking pawl 81a, 81b and 81c to press against on the drive plate ratchet 82 and guarantees to make release ratchet 85a, 85b and 85c to press against on the bearing dish ratchet 87.The ratchet tension device at one end is connected in ratchet support 83 and contacts with 85c with discharging ratchet 85a, 85b at the other end.One assembly hole 93 (not shown) that pass hub cap 67, bearing dish 6 and drive plate 34 can make an assembling pin (not shown) insert in the helical spring 80 of stand under load in the process of assembling transmission device 100.This assembling pin prevents the loss of tension of helical spring 80 and takes out later in the assembling of finishing transmission device 100.
With reference to Fig. 1,11,12 and 15, realize that by means of axle cable 602,604 and 606 self shifter of transmission devices 100, these cables at one end are connected in the parts of a motionless transmission device 100, for example hollow shaft 10 or fixed support 5a.Axle cable 602,604 and 606 is walked around axle pulley 630,632 and 634 then, and these axle pulleys all coaxially are positioned on axle 3a, 3b and the 3c.Axle cable 602,604 and 606 is also walked around separator pulley 636,638,640,644,646 and 648, and these pulleys all are connected on the separator extension 642, and this extension 642 can be rigidly connected to separator 8a, 8b and 8c.As more obvious illustrating in Figure 11 and 12, the axle cable 602,604 and 606 the other end are connected in a plurality of holes 620,622 and 624 in nonrotational annular bearing seat ring 816.A plurality of pouring weight cables 532,534 and 536 at one end are connected in a plurality of holes 610,612 and 614 in the swivel becket oblique crank Z bearing circle 806.Annular bearing 808 is positioned between swivel becket oblique crank Z bearing circle 806 and the nonrotational annular bearing seat ring 816, makes them can relative movement.
With reference to Figure 15, the transmission device 100 that comprises the cable wiring that is used for automaitc shfit is shown.
As shown in Fig. 1,9,11 and 12, pouring weight cable 532,534,536 is also walked around hub shell pulley 654,656 and 658, pass the hole in the hub shell 40, and enter in hollow spoke 504,506 and 508 (can see the most significantly among Figure 12), be connected in pouring weight 526,528 and 530 therein.Pouring weight 526,528 and 530 is connected in pouring weight auxiliary device 516,518 and 520 and admit supporting member from this auxiliary device, pouring weight auxiliary device 516,518 and 520 to be connected in one in its opposite end and take turns 514 or other rotors.When wheel 514 increased its rotating speed, pouring weight 526,528 and 530 is radially spurred left hub shell 40, and swivel becket oblique crank Z bearing circle 806 and nonrotational annular bearing seat ring 816 are axially pulled to hub cap 67.Nonrotational annular bearing seat ring 816 pulling axle cables 602,604,606, these axle cable pulling axle pulleys 630,632 and 634 make them more approach hollow shaft 10, and thereby make transmission device 100 be transformed to the higher speed shelves.When the rotating speed of wheel 514 reduces, one or more is positioned the direction that the hollow shaft 100 inner take up member 9 that also are held in place with shaft-cup 92 push axle pulley 630,632 and 634 away from hollow shaft 10 to, and thereby transmission device 100 is transformed to than bottom gear.
On the other hand, perhaps together with take up member 9, a plurality of take up member (not shown) can be connected in axle 3a, 3b and 3c on the opposite of axle pulley 630,632 and 634.
Still with reference to Fig. 1, transmission device 100 also can hand shift to skip over self-clanging gear-shift or to be used for replacing self-clanging gear-shift.One rotating gearshift 50 has internal thread, and it is screwed on the outside thread of gearshift threaded piece 52, and threaded piece 52 is connected on the hollow shaft 10.Gearshift 50 has a lid 53 that has a hole, and the hole is fitted on the bar 11, and bar 11 inserts hollow shafts 10.Bar 11 is shaped on screw thread in the position of stretching out hollow shaft 10 so that nut 54,55 can be screwed on the bar 11. Nut 54,55 is positioned at and covers 53 both sides.One shift level 56 is rigidly connected to gearshift 50 and provides a moment arm to bar 11.Gear shift cable 51 is connected in shift level 56 by groove 57a, 57b, the 57c on the bar.The variation that groove 57a, 57b on a plurality of bars, 57c provide speed and the simplification of gear shift.
Referring now to Fig. 1 and 10, the route of gear shift cable 51 leads to one handle 300 and coaxially twines thereon.When handle 300 was rotated in a first direction, gearshift 50 axially curled up on hollow shaft 10 or unwinding and bar 11 advanced hollow shafts 10 or pull out hollow shaft 10.When handle 300 was rotated in a second direction,, a gear shift spring 58 that is positioned at coaxially on the gearshift 50 made gearshift 50 return its initial position.Each end of gear shift spring 58 is connected in gearshift 50 and motionless parts, for example a framework (not shown).
As by can more obviously seeing among Figure 10, handle 300 is positioned on one handle bar (not shown) or other rigid elements.Handle 300 comprises a rotatory handling 302, and it comprises that a cable annex 304 and for the usefulness of the connection of gear shift cable 51 can make gear shift cable 51 twine the groove 306 of rotatory handlings 302.Also be provided with a flange 308 in order to avoid the user hinders the wiring of gear shift cable 51.Handle hook tooth 310 is positioned on the rotatory handling 302 at the face that the connects place of itself and a rotary clamp 314.When rotatory handling 302 was rotated in a first direction, handle hook tooth 310 was locked on the one group of anchor clamps hook tooth 312 in opposite.Anchor clamps hook tooth 312 forms ring and also is connected in rotary clamp 314, and when handle hook tooth 310 and anchor clamps hook tooth 312 are locked in a time-out, rotary clamp 314 rotates with rotatory handling 302.Making rotary clamp 314 rotate needed power can be adjusted with set screw 316 or other fastening pieces.When rotatory handling 302 was rotated in a second direction,, handle hook tooth 310 and anchor clamps hook tooth 312 were thrown off.Refer again to Fig. 1, when rotatory handling 302 was rotated in a second direction,, the tension force of gear shift spring 58 increased.One not rotary clamp 318 and not rotatory handling 320 prevent excessive the moving axially of the assembly of handle 300.
With reference to Figure 13 and 14, another embodiment of transmission device 900 is disclosed.For simplicity's sake, difference between transmission device 100 and the transmission device 900 only is discussed.
