Description
Technical field
The present invention relates to a kind of sychronisation of motor vehicles gear-shift mechanism, it includes the coupling that at least one has end face
It is conjuncted that there is the synchronous ring of end face with least one, set wherein coupling body and synchronization ring end face and be configured to have friction
Ground mutually reclines on the contact surface.
Background technology
Such sychronisation is known for example from the U1 of DE 20 2,006 019 959.This sychronisation is in addition
It is described to couple body and the shift gear of speed changer is connected with coupling body.In addition, generally there is one group of synchronous ring, the synchronization
Ring is used for the rotating speed of the adjustment member during shift process.Here, synchronous ring, in known embodiment be synchronous inner ring,
Abutted in friction on the end face for coupling body (Fig. 1 that the U1 of DE 20 2,006 019 959 are seen to this) by its end face.
Carried out for CONTACT WITH FRICTION low abrasion as far as possible, it is known that add oil groove in the end face of synchronous ring
Or oily depressed part.Oil can be collected in the oil groove or oily depressed part so that there is friction coupling between body and synchronous ring
In the case of contact, realize that friction reduces and then reduction of wearing and tearing.
Therefore, especially reduction abrasion, the abrasion is in synchronizing process by the relative rotation speed of component and in shift process
The axial force of period is produced.
Here, having the disadvantage, introduce the oil groove or the relative production technology expended of oily depressed part requirement and then improve synchronous
The manufacturing cost of device.
The content of the invention
The present invention is based on following purposes, and improvement starts to refer to the sychronisation of type so that avoid the shortcoming.Accordingly,
Manufacturing cost should be kept as small as possible, but ensure to realize the operation of the low abrasion of sychronisation simultaneously.Therefore, drop is passed through
The low friction coupled between body and synchronous ring, should be able to also improve the efficiency of speed changer.
The purpose is characterised by by the solution of the present invention, in the region of contact surface on the end face for couple body
Middle composition has bag-shaped recess.
The end face for coupling body is preferably at least in the region of contact surface by machining operation at this by geometric form
Shape the is determined or uncertain cutting knife of geometry is processed into its final geometry, but it is preferred therefore wherein to couple the end face of body
Ground is under any circumstance without hard finishing in contact surface region.
As an alternative, it is also possible to, the end face for coupling body is grasped at least in the region of contact surface by the processing without cutting
It is processed into its final geometry；But in this case it is also proposed that, the end face for coupling body preferably exists under any circumstance
All without hard finishing in the region of contact surface.
Accordingly, the end face of body is coupled by cutting ground or being processed without cutting herein --- if necessary also by two kinds of processing
The combination of type --- introduce or add processing mark, the processing mark partially will not again be moved by being refined to firmly
Remove；More precisely, the processing mark is used as oily depressed part.Couple the coarse surface obtained whereby of body therefore have pin
Property is used to form oily depressed part, supplied to improve with oil.
Certainly, recess targetedly can be also incorporated into end face.
Here, it is much preferred that the end face of synchronous ring does not have recess.Accordingly, targetedly abandon hitherto known
Recess (oily depressed part) is incorporated into the end face of synchronous ring and is disposed in mating surface, that is, is arranged on and couples body by ground
In end face.Certainly, but it is not excluded for, also recess (oil accommodates depressed part) is incorporated into synchronous ring according to the present invention additionally.
Recess can regularly but also can brokenly be arranged on the end face for coupling body.
The recess preferably there is edge to couple extension size of the ring circumferential direction of body between 0.02mm and 15mm.Recess
Radially also preferably there is the extension size between 0.02mm and 15mm.Further, it is preferable to propose, recess has edge
Couple depth capacity of the axial direction of body between 0.02mm and 1.0mm, preferably between 0.03mm and 0.2mm.
In the case where the processing mark typically obtained by cutting or without cutting processing can act as recess,
Also it can propose, recess is specifically molded.Tool --- is observed --- along the direction perpendicular to end face here, especially considering, recess
There is circle or ellipse construction.Here, can also propose, recess preferably has uniform concave surface.Here, recess
Size, shape and quantity can arbitrarily change in wide scope.It is sufficient that, recess is set between body and synchronous ring coupling
Put in the region of contact surface.
The recess coupled on body thus be accordingly used in oil conservator, enabling the oil groove on alternative synchronization ring.As long as also in synchronization
Oil groove is additionally provided with ring, then can further reduce the abrasion coupled between body and synchronous ring.
Brief description of the drawings
Embodiments of the invention are shown in the drawings.Accompanying drawing is shown：
Fig. 1 shows the radial section of a part for the sychronisation of motor vehicles gear-shift mechanism,
Fig. 2 show the radial section for coupling body of sychronisation and
Fig. 3 shows the view of --- observing in the axial direction --- of the section for coupling body according to Fig. 2.
Embodiment
Figure 1 illustrates a part for sychronisation 1.Outside synchronous ring 8, synchronous middle ring 9 and the synchronous ring 4 of inside
Form ring group.Sync-body 10 is fixed on transmission shaft for antitorque setting by interior teeth portion.In addition to sync-body 10,
It is provided with shift gear 11.Body 2 is coupled to be connected with shift gear 11.The body that couples has recess 12, and the drive of middle ring 9 is convex
13 are played to be joined in the recess.Middle ring 9 forms first with the friction fit face of the synchronous ring 8 as the outside for coordinating cone
Friction pair 14；Middle ring 9 forms the second friction pair 15 with the friction fit face of internal synchronous ring 4.Shift gear 11 and synchronization
The connection of body 10 is carried out via sliding sleeve 16.
The inward flange 17 of internal synchronous ring 4 is interrupted by the portion of leaving a blank and hidden partially by the protuberance of sync-body 10
Lid.Protuberance is joined in the portion of leaving a blank.Therefore, internal synchronous ring 4 is shape-ordinatedly connected with sync-body 10.Outside synchronization
Ring 8 is ordinatedly connected via its edge shape with sync-body 10.Outside synchronous ring 8 and the form fit of sync-body 10 are via it
The portion 18 of leaving a blank at edge is carried out.
Body 2 is coupled with end face 3, the end face is structured to the fortune for having friction of the end face 5 of the synchronous ring 4 of inside
OK.Accordingly, couple body 2 and internal synchronous ring 4 mutually reclines during shift process on contact surface 6.
As obtained from Fig. 2 and 3 overview, recess 7 is introduced in the end face 3 for couple body 2.The recess currently has pin
Property is added by Cutting Process and --- as drawn from Fig. 3 --- is regularly placed on contact surface 6.
The extension size of the recess 7 constituted herein spherically along ring circumferential direction U with a and radially R with b tables
Show.In axial direction A is observed, and recess 7 has depth t.
Recess 7 contributes to：Oil can be attached on the end face 3 for coupling body 2, and the oil is then in gearshift or synchronizing process phase
Between in order to which the purpose of lubrication provides synchronous ring 4 internally and couples between body 2.Therefore no longer need in the side 5 of synchronous ring 4
