Description
Technical field
The present invention relates to a kind of gearshift driver/conveyer and a kind of flywheel sychronising formula speed changer that is used for flywheel sychronising formula speed changer with this gearshift driver.
Background technique
In the flywheel sychronising formula speed changer of routine, be typically provided with sync-body and with the synergistic independent gearshift clutch collar of this sync-body, sync-body can not be arranged on the transmission shaft with the relative rotation, and the gearshift clutch collar can not be with the relative rotation with respect to sync-body but can be provided with moving axially.For this speed changer of simplification on structure and manufacturing process, known in the prior art so-called " gearshift driver ", it has annular solid, and each annular physical efficiency is rotated around the transmission axis.Annular solid has first profile at its radially inner side, is used for can not with the relative rotation and can connecting with transmission shaft with moving axially; Have second profile at its radial outside, but be used for axially connecting with the shifting element of axial motion; And have synchronous breach between radially inner side and radial outside, each axial projections of a friction ring can embed in each synchronous breach.This gearshift driver that is used for flywheel sychronising formula speed changer is for example known by DE 1 101 057 A.In the document, the gearshift driver that is called blade tooth clutch gear ring is made up of two rotational symmetric dishes, and these two rims axially are adjacent to each other.Constitute internal tooth portion on the radially inner side of described dish, described internal tooth portion embeds in the outer toothed portion of transmission shaft.The gearshift fork acts on the radial outside of described dish, so that the gearshift driver moves axially on transmission shaft.Be provided with opening between gearshift radially inner side of driver and radial outside in two dishes, wherein the tooth of the tooth of synchronizing ring and free pulley all can be embedded in each opening, so that synchronizing ring or free pulley along the circumferential direction connect with the gearshift driver.
The loaded down with trivial details structure that has sync-body and switch clutch collar on manufacturing process that the driver solution of DE 1 101 057 A provides by the smooth stamping part that uses the existing structure advantage and make two symmetries of advantage that beginning mentions.
But in the prior art the drive mechanism of Miao Shuing still make loaded down with trivial details because the annular disk of two symmetries must relative to each other fix, and the opening in these two dishes must cooperate accurately with synchronizing ring in tooth portion and the tooth portion in the free pulley coordinate mutually.Correspondingly, relevant dirivig member will be observed narrower tolerance of size, to guarantee the good function of flywheel sychronising formula speed changer.
Summary of the invention
Therefore, the object of the present invention is to provide a kind of gearshift driver that is used for flywheel sychronising formula speed changer, it has the structure of simplification in gearshift reliable in function, shifting comfort height and high life, and can be with less manufacturing expense production.
According to the present invention, this purpose realizes by a kind of gearshift driver of flywheel sychronising formula speed changer, it has the annular solid around the rotatable one of transmission axis, and this annular solid has first profile at its radially inner side, is used for can not with the relative rotation and connecting with transmission shaft with moving axially; Have second profile at its radial outside, be used for axially connecting with the shifting element that can move; And between radially inner side and radial outside, has synchronous breach, each axial projections of friction ring can embed in each synchronous breach, wherein annular solid also has independent gearshift breach between radially inner side and radial outside, is used for can not connecting with the relative rotation with the clutch body.Therefore this gearshift driver annular solid of only also having unique one, the independent breach that in this annular solid, is configured for the breach that connects with friction ring and is used for connecing with clutch sports association.Because preferable configuration is the structure of one of the annular solid of flat annular disk, form the drive mechanism of simple especially and axially compact here.In addition because less tolerance issues appears in described independent breach, because these breach only must be aimed at friction ring or only must aim at the clutch body.
Preferably, first profile is an internal tooth portion, and/or second profile be radial outside around the gearshift groove.The profile that is used for can not being connected with the relative rotation and being used for transmission shaft axial gear shift operation has been proved to be very reliable, and can be integrated in the annular solid of one with expense seldom.Except outer ring around the gearshift groove, the simple edge of sealing along the circumferential direction certainly also can only be set, the operating element that this surrounded by edges is forked.
In a kind of mode of execution of gearshift driver, in annular solid, be provided with the pressure piece opening, be used to hold spring-loaded pressure piece.But the preferred radial motion of pressure piece, wherein annular solid can easily be configured to and with the radially-directed portion that acts on pressure piece to be held.
In each pressure piece opening, can distinguish an integrated synchronous breach and/or two gearshift breach.If an integrated synchronous breach, then pressure piece acts directly on the axial projections of friction ring and realizes the simple and reliable presynchronization of speed changer thus.If integrated two gearshift breach not only can be realized a large number of gearshift breach in annular solid in the pressure piece opening, and the along the circumferential direction equidistant distribution of breach that can realize shifting gears, this causes the advantage aspect material stress and manufacturing expense.
Preferably, the synchronous breach of at least one of annular solid defines by synchronous inclined-plane, and these synchronous inclined-planes can recline with the synchronous inclined-plane that constitutes on the axial projections that sets of friction ring accordingly.After flywheel sychronising formula speed changer was by clutch body presynchronization, it is synchronous that synchronously the inclined-plane is used for actual transmission, i.e. relative rotation between restriction gearshift driver and the friction ring, and axially gearshift power is converted to the restoring force of sensing along the circumferential direction.Particularly preferably, all synchronous breach that are integrated in the pressure piece opening are defined by synchronous inclined-plane, with reduce surface pressure and reduce thus to shift gears driver and friction ring in material stress.
In a form of implementation of gearshift driver, the gearshift breach is than the radially more inner setting of synchronous breach.At this, radially be not provided with overlappingly in order to stablize preferred breach.
Particularly, annular solid can have the gearshift breach of Duoing than synchronous breach.This considers the following fact: must be at the gear of having inserted via the whole Engine torque of edge transfer of gearshift breach or gearshift breach, and via synchronous breach or synchronously the edge of breach only must be delivered in the simultaneous force that occurs in the speed changer.Owing to constituted independent gearshift breach and synchronous breach, its quantity can be matched with the load of corresponding appearance with haveing nothing to do each other.Therefore, the quantity of breach can reduce synchronously, and this not only causes simple manufacturing but also causes shifting gears the advantages of higher stability of driver.
In another form of implementation of gearshift driver, being provided with gearshift pin, each bearing pin of shifting gears stretches out and is embedded in the gearshift pin opening that constitutes on the clutch body to the gearshift breach that extends through annular solid, at least one end face axial of protruding in annular solid.The gearshift pin preferably is connected with annular solid regularly at this, for example is pressed in the gearshift breach of annular solid.Particularly preferably, the gearshift pin protrudes in two end faces of annular solid.Therefore, when the clutch body was arranged on the axial both sides of gearshift driver, each gearshift pin can be used for shape and join the gearshift pin opening of two clutch bodies sealedly to and be used for the power transmission.
In this embodiment, each gearshift pin can have backstop, is used to make the gearshift pin with respect to the annular solid axially locating.This backstop for example be configured to around flange and when gearshift pin is fixed on the annular solid as the installation assisting section.Can bring all gearshift pins the axial position of the preferred center identical in simple mode by backstop, thereby all gearshift pins embed simultaneously in the gearshift pin opening that sets with it in the clutch body when the gearshift driver moves axially during shift process with respect to annular solid.Therefore can avoid overload and undesirable transmission device scratch of indivedual gearshift pins reliably.
In order to be convenient to that in shift process the gearshift pin opening that sets that imports in the friction ring is sold in gearshift, gearshift is sold preferable configuration and is, makes each gearshift sell at least one gearshift pin end, particularly sell the end tapered convergents two axial gearshifts.Particularly, gearshift pin end for example is configured to point, protruding spherical or tilt.
In addition, each gearshift pin can have the gearshift gap segments, and in abutting connection with annular solid, wherein sell in the gearshift gap segments and axially have side between the gearshift pin end and cut by gearshift under mounted state for this gearshift gap segments.In shift process, the gearshift driver moves to a drive range by means of axial gearshift power after realizing synchronization, and at this drive range, gearshift is sold in the gearshift pin opening that embeds the clutch body and inserted the gear of hope.Cut by described side, even the gearshift driver still remains on its (shifting gears) position under the situation of the power of not shifting gears shift process after, from the gear of inserting not automatic " disengaging " again.
In addition, the present invention also comprises a kind of inertia force of motor vehicles synchronous mode speed changer that is used for, and comprising: the axially movable gearshift driver of above-mentioned energy; The friction ring that at least one along the circumferential direction connects with the gearshift driver, this friction ring has axial projections, and each projection can put in the synchronous breach of gearshift driver; And at least one clutch body, it can along the circumferential direction can not connect with the gearshift driver with the relative rotation, wherein axially outstanding projection is molded and shaped on the clutch body, and each projection embeds in the gearshift breach of gearshift driver can not connect with the relative rotation with the gearshift driver.In this case, an independent member that is connected with the follower of speed changer regularly is called as the clutch body.The gearshift driver only comprises the annular solid of one in this form of implementation of speed changer, this annular solid particularly is configured to flat annular disk and has a plurality of molded and shaped profiles and/or breach.These profiles and/or breach are realized different functions, and are arranged so that the gearshift driver has the power that enough stability is occurred with transmission, and can be with less manufacturing expense manufacturing.Clutch body with axially outstanding projection equally can be for example as the moulding plate with less expense manufacturing, projection can be pressed in this plate simply.
In order to be easy to when inserting gear projection be penetrated in the gearshift breach of gearshift driver, the preferred structure like this of clutch body: each projection court is axial projection end convergent freely.In addition, the projection end can be similar to the above-mentioned gearshift pin end structure that gearshift is sold in an advantageous manner freely.Particularly, each projection can be at first enlarges towards axial projection end freely, convergent then, cuts thereby form the side of having mentioned in the gearshift pin, and this side is cut at the gear of having inserted the driver of will shifting gears and remained on the position that it has been shifted gears.
At last, the present invention also comprises a kind of inertia force of motor vehicles synchronous mode speed changer that is used for, comprise: the axially movable gearshift driver of above-mentioned energy, the friction ring that at least one along the circumferential direction connects with the gearshift driver, this friction ring has axial projections, each projection can put in the synchronous breach of gearshift driver, and at least one clutch body, its can be along the circumferential direction can not connect with the gearshift driver with the relative rotation and be arranged on gearshift sells with the annular solid opposing end faces on, wherein the clutch body has gearshift pin opening, and the gearshift pin can embed when the gearshift driver moves axially in this gearshift pin opening.In this form of implementation of speed changer, gearshift driver and clutch body all only have the breach of gearshift or gearshift pin opening, and described gearshift breach or gearshift pin opening can for example be pressed the stamping process manufacturing with minimum expense.Yet for shape connects two members sealedly, independent gearshift pin is essential, and it can be equally with less expense manufacturing, but must be installed in advance on the annular solid, to form the gearshift driver.
In a form of implementation of flywheel sychronising formula speed changer, the radial outside of clutch body is configured to the rubbing surface of taper, and can recline with the rubbing surface of the adjacency of friction ring.Engage because this structure is the embedding tooth with axially outstanding projection, no longer need conventional outer toothed portion at the radial outside of clutch body, thereby the radial outside of clutch body can be configured to rubbing surface in an advantageous manner.And this helps simplifying on the structure clutch body and therefore simplifies whole flywheel sychronising formula speed changer.

Embodiment
Fig. 1 to 6 illustrates first form of implementation that is used for inertia force of motor vehicles synchronous mode speed changer 10, described speed changer have according to first form of implementation can axially movable gearshift driver 12, be arranged on two clutch bodies 26 of the axial both sides of gearshift driver 12, and be arranged on the axial both sides of gearshift driver 12 and 14 two friction rings 16 that connect with the driver 12 of shifting gears along the circumferential direction equally, described clutch body can be along the circumferential direction 14 can not connect with gearshift driver 12 with the relative rotation, described friction ring has axial projections 18,20,22, described axial projections can put in the synchronous breach 24 of gearshift driver 12.
Clutch body 26 is member independent but that be connected with the follower 28 that sets (referring to Fig. 2 and 3) regularly respectively.Particularly, clutch body 26 for the moulding plate and for example with follower 28 solderings, melting welding, the bonding or pressing that set.
In addition, the radial outside of clutch body 26 is configured to the rubbing surface 64 of taper, and can recline with the rubbing surface 62 of friction ring 16 and form the friction be connected.
At this particularly, one of two rubbing surfaces 62 correspondingly are equipped with friction facing (scattering sintering liner, organic liner, carbon liner etc.).
In first form of implementation of speed changer 10, axially outstanding projection 30 is molded and shaped on the end face of clutch body 26, and these projections embed in the gearshift breach 32 of gearshift drivers can not connect with the relative rotation with gearshift driver 12.
The gearshift driver 12 of flywheel sychronising formula speed changer 10 comprises that it is configured to flat annular disk according to Fig. 1 to 6 around the annular solid 34 of the rotatable one of transmission axis A.Annular solid 34 has first profile 36 at its radially inner side, is used for can not with the relative rotation and can connecting (see figure 4) with transmission shaft 38 with moving axially; Have second profile 40 at its radial outside, but be used for axially connecting (see figure 2) with the shifting element 42 of axial motion; And have synchronous breach 24 between radially inner side and radial outside, the axial projections 18,20,22 of friction ring 16 can embed in each synchronous breach.
In addition, annular solid 34 also has independent gearshift breach 32 between radially inner side and radial outside, is used for can not connecting with the relative rotation with clutch body 26.
In first form of implementation of flywheel sychronising formula speed changer 10, first profile 36 is internal tooth portion (seeing Fig. 1 and 6), second profile 40 be radial outside around gearshift groove 46, but the shifting element 42 of axial motion can embed (see figure 2) in this gearshift groove.Alternately, second profile 40 also can only be the edge of 14 sealings along the circumferential direction of annular solid 34, but is configured to shifting element 42 these edge (see figure 8)s of encirclement of forked axial motion.
Except synchronous breach 24 and gearshift breach 32, in annular solid 34, between its radially inner side and its radial outside, also be provided with the pressure piece opening 48 that is used to hold spring-loaded pressure piece 50.But pressure piece 50 radial motions also load (seeing Fig. 2 and 4) by spring element 52 radially outwards towards axial projections 18.
As shown in Figure 6, be respectively equipped with guiding groove 54 in pressure piece opening 48, pressure piece 50 can move radially ground and immovably remain in this guiding groove to the full extent with tangential direction vertically.
As can be known preferable among this external Fig. 4 and 6, the integrated synchronous breach 24 of difference and two gearshift breach 32 in each pressure piece opening 48, just, the mutual transition of each opening and breach.
In order to realize that in speed changer 10 at least one synchronous breach 24 is defined by synchronous inclined-plane 56 (see figure 6)s synchronously, described synchronous inclined-plane can recline with synchronous inclined-plane 58 (see figure 1)s on the axial projections that sets 18 that is configured in friction ring 16 accordingly.Therefore, the relative rotation between inclined- plane 56,58 restriction gearshift drivers 12 and the friction ring 16 synchronously.In addition, synchronously inclined-plane 56, the 58 power F that will axially shift gears changes the restoring forces of 14 effects along the circumferential direction into, by this restoring force, gearshift driver 12 and follower 28 to be shifted gears along the circumferential direction 14 are relative to each other aimed at after synchronization, make projection 30 embed in the gearshift breach 32 of clutch body 26 when the direction towards follower 28 moves axially at gearshift driver 12.
In first form of implementation according to the gearshift driver of Fig. 1 to 6, inclined-plane 56 is arranged on all synchronous breach 24 that are integrated in the pressure piece opening 48 synchronously.
According to Fig. 4 and 6 also as can be known, gearshift breach 32 is provided with than synchronous breach 24 radially more innerly.Because the axial projections 18,20,22 of friction ring 16 embeds in the synchronous breach 24, therefore the radius that can maximize friction ring 16 by this mode with and rubbing surface 62.Therefore produce big friction torque when transmission is synchronous, described friction torque causes the quick rotating speed compensation between gearshift driver 12 and clutch body 26 or follower 28.
In addition, the annular solid 34 of gearshift driver 12 has the gearshift breach 32 than synchronous breach more than 24, because must transmit all Engine torques via gearshift breach 32, and only must transmit a spot of friction torque via synchronous breach 24.Because it is constructed individually, the quantity of breach 24 and gearshift breach 32 can be matched with the load of corresponding appearance individually synchronously.Therefore, particularly the quantity of breach 24 can reduce synchronously, and this causes the higher rigidity of annular solid 34 and gearshift driver 12 owing to less member dies down.
Therefore, for example axial projections 18 is embodied as synchronous projection, and it has presynchronization inclined-plane 60 on the one hand, and pressure piece 50 acts on this presynchronization inclined-plane (sees Fig. 2 and 3); Have previous described synchronous inclined-plane 58 on the other hand, this synchronous inclined-plane can act on the synchronous inclined-plane 56 of complementation of synchronous breach 24.
When gearshift power F is applied on the annular solid 34 of gearshift driver 12, pressure piece 50 axially presses the presynchronization inclined-plane 60 of corresponding friction ring 16, and the conical friction face 62 of friction ring 16 correspondingly axially loads the rubbing surface 64 (presynchronization) of the same taper of clutch body 26 therewith.
Between friction ring 16 and clutch body 26, form after friction is connected, friction ring and clutch body since speed discrepancy with respect to 12 rotations of gearshift driver, touches each other up to synchronous inclined- plane 56,58 and thus restriction rotate relatively.
The power of shifting gears after synchronous speed F is enough to make synergistic synchronous inclined- plane 56,58 along sliding over each other and gearshift driver 12 being reversed up to a neutral position with respect to friction ring 16, in this neutral position, further vertically towards the direction motion of follower 28 to be shifted gears, and molded and shaped axial projection 30 shapes on clutch body 26 embed in the gearshift breach 32 gearshift driver 12 sealedly by gearshift power F.
The axial projections 20 of friction ring 16 is embodied as attachment tabs, and it is in axial direction relative to each other fixing with two friction rings 16 under the state of the assembling of speed changer 10.For this reason, the projection 20 of the projection 20 of a friction ring 16 and another friction ring 16 is equipped on respectively each other and according to the type structure of the building block of complementation.Projection 20 shape under the state of the assembling of speed changer 10 that is equipped on each other embeds each other sealedly, thereby friction ring 16 only can together in axial direction move.For projection 20 is installed, each friction ring 16 only has two projections 20, and it is opposed along diameter respectively, thereby each ring must be radially towards motion each other, so that projection 20 is inserted each other.
In order to reduce material stress and the surface pressure between sync period, also can be susceptible to: projection 20 and/or projection 22 are similar to projection 18 and also have synchronous inclined-plane 58.In this case, also on the corresponding synchronous breach 24 that sets in annular solid 34 complementary synchronous inclined-plane 56 is set.
Fig. 7 to 12 illustrates second form of implementation that has according to the flywheel sychronising formula speed changer 10 of the gearshift driver 12 of second form of implementation.The total of this speed changer 10 is identical in this 26S Proteasome Structure and Function mode with first form of implementation described above of speed changer 10 with functional mode on its principle, therefore about the description of this some reference, hereinafter only discuss the structural special way of second form of implementation to Fig. 1 to 6.
Different with first form of implementation, except annular solid 34, also comprise gearshift pin 66 according to the gearshift driver 12 of second form of implementation, it extends axially the gearshift breach 32 that passes annular solid 34.Gearshift pin 66 axially protrudes in two axial ends of annular solid 34 under the installed state according to Fig. 8 and 9, and can be embedded in the gearshift pin opening 68 of structure on the clutch body 26.Gearshift pin 66 is installed in advance on the annular solid 34 and after it is installed and is permanently connected with annular solid 34, particularly is pressed into regularly in the gearshift breach 32 of annular solid 34.
Except can axially movable gearshift driver 12, also have two according to the speed changer 10 of second form of implementation and be arranged on the axial both sides of gearshift driver 12 and along the circumferential direction 14 friction rings 16 that connect with gearshift driver 12 and two clutch bodies 26 that are arranged on the axial both sides of the driver 12 of shifting gears equally, friction ring has axial projections 18,20,22 respectively, each projection can put in the synchronous breach 24 of gearshift driver 12, and the clutch body can be along the circumferential direction 14 can not connect with gearshift driver 12 with the relative rotation.In second form of implementation of speed changer 10, clutch body 26 has gearshift pin opening 68, and gearshift pin 66 can embed when gearshift driver 12 moves axially in the gearshift pin opening.
Figure 11 and 12 illustrates the perspective view and the longitudinal section of gearshift pin 66.As seen preferable in these detailed drawing, gearshift pin 66 have backstop 70 so that gearshift pin 66 with respect to annular solid 34 axially locating, this backstop be configured in this embodiment around flange and as assisting section is installed.
In addition, gearshift pin 66 is at two axial 72 tapers ground, gearshift pin end convergent, to be easy to " penetrating " or to join in the gearshift pin opening 68 of clutch body 26.Other structures that can realize simply penetrating of gearshift pin end 72 are shown in Figure 13 a to 13d, and slightly pointed, the protruding gearshift pin end 72 spherical or that tilt of tool.
According to Figure 12, each gearshift pin 66 has gearshift gap segments 74, and in abutting connection with annular solid 34 (see figure 9)s, wherein gearshift pin 66 is sold in gearshift gap segments 74 and axial gearshift and had side respectively between the end 72 and cut 76 under mounted state for it.Be used to make gearshift pin 66 when connecting gear, to sell opening 68 and do not having under the situation of gearshift power F of axial action to keep engaging even side cuts 76, and the gear of having inserted can self not break away from once more with gearshift.In order to break away from the gear of on, the opposite force that is in reverse to gearshift power F is essential, to overcome the axial confining force of 76 effects of being cut by side in the transmission position of on.
Certainly, can be transferred to molded and shaped projection 30 on clutch body 26 similarly about the above explanation of gearshift pin end 72 according to first form of implementation of the speed changer 10 of Fig. 1 to 6.Therefore, each projection 30 also can be towards axial projection end 78 convergents freely in this case, projection 30 are joined in the gearshift breach 32 of annular solid 34 being easy to.
Being similar to gearshift pin end 72, also can being embodied as point, protruding spherical or tilt in this projection end 78 according to Figure 13 a to 13d.
Be similar to gearshift pin end 72 equally, each projection 30 also can at first enlarge and then convergent axial projection end 78 towards it freely, cuts 76 thereby form favourable side.
Figure 14 illustrates another form of implementation of gearshift driver 12, and wherein to construct but be different from above-mentioned form of implementation be not to be configured to flat annular disk on the ground of annular solid 34 same one.Annular solid 34 has axial centre face E in this case, wherein (promptly radially at first profile 36, internal tooth portion at radially inner side) with second profile 40 (promptly, on the radial outside along the circumferential direction 14 around the edge) between constitute outer toothed portion 80 on the annulus section 82 at annular solid 34, wherein annular solid 34 such moulding make annulus section 82 extend in axial direction each other/alternately and leave median plane E.
