Abstract
The invention relates to a synchronization device (1) for a motor vehicle gear transmission, comprising at least one coupling body (2) having an end face (3) and at least one synchronization ring (4) having an end face (5), wherein the end faces (3, 5) of the coupling body (2) and of the synchronization ring (4) are arranged and designed to frictionally abut against each other on a contact surface (6).
Description
Technical field
The present invention relates to a kind of synchronizer of motor vehicle gear-shift transmission, it comprise at least one have end face be coupled body and at least one has the synchronizing ring of end face, be wherein coupled the arranging with the end face of synchronizing ring and be configured to mutually recline on the contact surface with friction of body.
Background technique
Such synchronizer is such as known from DE 20 2,006 019 959 U1.This synchronizer has in addition and is coupled body, described in be coupled body and be connected with the shift gear of speed changer.In addition, usually there is one group of synchronizing ring, described synchronizing ring is used for the rotating speed adjusting component during shift process.At this, synchronizing ring, be synchronous inner ring in known mode of execution, abut in friction to be coupled on the end face of body by its end face and (this is seen to Fig. 1 of DE 20 2,006 019 959 U1).
Abrasively carry out in order to described rubbing contact is low as far as possible, it is known that add oil groove or oily depressed part in the end face of synchronizing ring.Can oil be collected in described oil groove or oily depressed part, make when be coupled to there is rubbing contact between body and synchronizing ring, realize friction and to reduce and then wearing and tearing reduce.
Therefore, especially reduce wearing and tearing, described wearing and tearing are produced by the relative rotation speed of component and the axial force during shift process in synchronizing process.
At this, shortcoming is, introduces the production technology of described oil groove or oily depressed part requirement relative expenses and then improves the manufacture cost of synchronizer.
Summary of the invention
The present invention is based on following object, improve and start the synchronizer mentioning type, make to avoid described shortcoming.Accordingly, manufacture cost should be kept little as far as possible, but guarantee the operation of the low wearing and tearing realizing synchronizer simultaneously.Therefore, by reducing the friction be coupled between body and synchronizing ring, the efficiency of speed changer should be able to also be improved.
Described object is by the feature of solution of the present invention, and the end face being coupled body is configured with bag-shaped recess in the region of surface of contact.
The end face being coupled body is determined by geometrical shape by cutting operation in this region preferably at least at surface of contact or the uncertain cutting knife of geometrical shape is processed into its final geometrical shape, but the end face being therefore wherein coupled body does not preferably under any circumstance have hard fine finishing in surface of contact region.
As an alternative, also possible that, the machining operation that the end face being coupled body is at least cut by nothing in the region of surface of contact is processed into its final geometrical shape; But propose in this case, the end face being coupled body does not preferably under any circumstance have hard fine finishing in the region of surface of contact yet.
Accordingly, at this, by cutting ground or process without cutting the end face being coupled body---if desired also by the combination of two kinds of processing types---, introduce or add processing mark, described processing mark can not be removed at least in part again by hard fine finishing; Or rather, described processing mark is used as oily depressed part.The coarse surface obtained whereby being coupled body therefore targetedly for the formation of oily depressed part so that improvement oil is supplied.
Certainly, recess also can be incorporated in end face targetedly.
At this, it is most preferred that, the end face of synchronizing ring does not have recess.Accordingly, to abandon targetedly recess (oily depressed part) being incorporated in the end face of synchronizing ring hitherto knownly and to be arranged in fitting surface, to be namely arranged on and to be coupled in the end face of body.Certainly, but do not get rid of according to the present invention, additionally also recess (oil holds depressed part) is incorporated in synchronizing ring.
But recess also can be arranged on brokenly regularly and be coupled on the end face of body.
Described recess preferably has the extension size of ring circumferential direction between 0.02mm and 15mm along being coupled body.Recess radially also preferably has the extension size between 0.02mm and 15mm.In addition, preferably propose, recess has the maximum depth of axial direction between 0.02mm and 1.0mm, preferably between 0.03mm and 0.2mm along being coupled body.
When typically by cut or recess can be act as without the processing mark that obtains of processing cut, also can propose, recess is specifically shaping.At this, especially consider, recess that---observing along the direction perpendicular to end face---has structure that is circular or ellipse.At this, can also propose, recess preferably has the surface of even concavity.At this, the size of recess, shape and quantity can change arbitrarily in wide scope.Be sufficient that recess is arranged in the region of surface of contact being coupled between body and synchronizing ring.
Be coupled recess on body therefore for oil conservator, make it possible to the oil groove on alternative synchronization ring.As long as be also additionally provided with oil groove in synchronizing ring, so the wearing and tearing be coupled between body and synchronizing ring can be reduced further.
Accompanying drawing explanation
Embodiments of the invention shown in the drawings.Accompanying drawing illustrates:
Fig. 1 illustrates the radial section of a part for the synchronizer of motor vehicle gear-shift transmission,
Fig. 2 illustrate synchronizer the radial section being coupled body and
Fig. 3 illustrates the view being coupled---observing in the axial direction---of portion's section of body according to Fig. 2.
Embodiment
A part for synchronizer 1 shown in Figure 1.Outside synchronizing ring 8, the synchronously synchronizing ring 4 of central ring 9 and inside form ring group.Sync-body 10 is fixed on transmission shaft by interior teeth portion in order to antitorque setting.Except sync-body 10, be provided with shift gear 11.Be coupled body 2 to be connected with shift gear 11.The described body that is coupled has recess 12, and the drive projection 13 of central ring 9 joins in described recess.Central ring 9 forms the first friction pair 14 with the friction fit face as the synchronizing ring 8 coordinating the outside of cone; Central ring 9 forms the second friction pair 15 with the friction fit face of inner synchronizing ring 4.The connection of shift gear 11 and sync-body 10 is carried out via sliding sleeve 16.
The bump of the inward flange 17 of inner synchronizing ring 4 by the portion's of leaving a blank interruption and partially by sync-body 10 hides.Bump joins in the portion of leaving a blank.Therefore, inner synchronizing ring 4 form fit ground is connected with sync-body 10.Outside synchronizing ring 8 is connected with sync-body 10 ordinatedly via its edge shape.The synchronizing ring 8 of outside is carried out with the portion of leaving a blank 18 of the form fit of sync-body 10 via its edge.
Be coupled body 2 and have end face 3, described end face is configured to the operation having friction of the end face 5 of the synchronizing ring 4 for inside.Accordingly, the synchronizing ring 4 being coupled body 2 and inside mutually reclines during shift process on surface of contact 6.
As what obtain in the overview from Fig. 2 and 3, in the end face 3 being coupled body 2, introduce recess 7.Described recess is current to be added by milling process targetedly and---as drawn from Fig. 3---is placed in regularly on surface of contact 6.
This spherical recess 7 formed extension size along ring circumferential direction U with a and radially R represent with b.In axial direction A observes, and recess 7 has degree of depth t.
Recess 7 contributes to: oil can be attached to and be coupled on the end face 3 of body 2, and described oil is provided in inner synchronizing ring 4 in order to the object of lubricating subsequently and is coupled between body 2 during gearshift or synchronizing process.Therefore the corresponding recess 7 in the side 5 of synchronizing ring 4 is no longer needed.
