Description
Technical field
The present invention relates to a kind of clutch for automatic mechanical transmission, it is more particularly to a kind of with rack-and-pinion and
The clutch compressing disc of planetary mechanism, and the clutch comprising the clutch compressing disc, described device can be by between rack-and-pinion
Engagement rotation promote platen axial movement to realize the engagement of clutch with separating.
Background technology
In the dynamical system of vehicle, clutch is the key components and parts for connecting engine and gearbox.At present, it is applied to
The clutch of vehicle automatic mechanical speed variator all uses traditional diaphragm spring clutch substantially.Such clutch is deposited
In following deficiency：1）Because the displacement of the active force and release bearing of diaphragm spring separation finger is not linear relationship, in clutch
During device operating mechanism start makes clutch engagement, it is easy for producing the uneven phenomenon of thrust, and then make clutch
Self-excited vibration is produced, auto NVH (N refers to Noise, and V refers to Vibration, and H refers to Harshness) performance is had a strong impact on.2）When from
The operating point location change of abrasion diaphragm spring occurs for clutch, and clutch separation refers to separating force increase, thrust significant change.And from
Corresponding adjustment can not but be made in time by moving retaining device, and then separation can be caused difficult, engage not in place, transmission moment of torsion energy
The problems such as power declines.3）In order to allow clutch to realize the function of separation-engagement, the dynamical element of clutch operating device needs instead
Diaphragm spring is promoted again.Because the axial rigidity of diaphragm spring is very big, it is therefore desirable to which dynamical element provides larger axial force,
Big energy is also consumed simultaneously, is unfavorable for the fuel economy of automobile.4）In traditional diaphragm spring clutch, due to building ring
Border is severe, clutch compressing disc architectural characteristic, easily by thermal destruction；Meanwhile, fatigue fracture also occurs in diaphragm spring, has a strong impact on
Clutch uses reliability.The present invention breaks through transmission clutch structural limitation, using rack-and-pinion coordinate Hang Xing mechanisms realize from
Clutch is engaged with separating, to solve to be driven the drawbacks described above that diaphragm spring clutch is present.
The content of the invention

Wheel 9 and clutch case 2 are affixed, can not be relatively moved between the two；So, the phase between driving neck 13 and clutch case 2
Can only be along groove direction to motion.
Platen 6, clutch case 2, the clutch initiative part that planetary gear 7 and planet carrier 8 are constituted is shown respectively in Fig. 4 to Fig. 7
The motion principle schematic diagram of sectional view and clutch the engagement separation platen 6 divided, planetary gear 7 and planet carrier 8.Drive neck 13 with
Platen 6 is affixed, can not be relatively moved between the two.When driving neck 13 is produced along groove direction relative to clutch case 2
During relative movement, platen 6 is driven in axial direction（Rx directions）While mobile rotation is generated relative to clutch case 2.Planet tooth
Wheel 7 and planet carrier 8 are arranged between platen 6 and clutch case 2.Planetary gear 7 and the rack phase on platen 6 and clutch case 2
Engagement.When platen 6 produces relative rotation relative to clutch case 2, planetary gear 7 and planet carrier 8 are around transmission input shaft 5
While revolution, also around the axle center rotation of oneself.Plane where the reticule of every section of arc-shaped rack on platen 6 with it is vertical
The angle of the plane of transmission input shaft 5 is 5 ° ~ 10 °, and planetary gear 7 also promotes platen 6 in axial direction while rotation（Rx
Direction）It is mobile.Planetary gear 7 and driving neck 13 collective effect promote platen 6 to engage.
The sectional view and axonometric drawing that clutch engaged-separated operating mechanism is shown respectively in Fig. 8, Fig. 9.Servomotor 101 with
Shaft coupling 102 is connected, use quincunx shaft coupling preferably.The other end of shaft coupling 102 is connected with screw mandrel 105.Connector 103 leads to
Screw thread is crossed to be connected with screw mandrel.The base of servomotor 101 is fixed on gear box casing, in axial direction（Rx directions）It can not move.When
Servomotor 101 is in the circumferential（Ux directions）During rotation, shaft coupling 102 and the synchronous axial system of screw mandrel 105 are driven.Screw mandrel 105 is turning
Connector 103 is promoted in axial direction by screw thread rotation when dynamic（Rx directions）It is mobile.Drive link 104 is welded with connector 103
Together, while affixed with mounting flange 106.The other end of mounting flange 106 and gear box casing are affixed.Drive link 104 with
Mounting flange 106 is fulcrum formation lever.The other end of drive link 104 is in axial direction（Rx directions）Opposite direction is moved.Driving connects
The other end of bar 104 is embedded in the chute of thrust mechanism 108 in forked, is connected with rotating decoupled mode with thrust mechanism 108
Connect.When drive link 104 one end together with connector 103 in axial direction（Rx directions）When mobile, drive link 104 and thrust machine
Structure 108 is in the axial direction（Rx directions）Opposite direction is moved.Thrust mechanism 108 is embedded on adpting flange 107, adpting flange 107
To the effect supported to thrust mechanism 108 and radial displacement is constrained（Ax directions）.Adpting flange 107 is fixed in change by bolt
On fast tank shell, axially（Rx directions）It is fixed.Lubricating grease is scribbled between thrust mechanism 108 and adpting flange 107 to reduce axial direction
The sliding friction produced when mobile.Angular contact ball bearing 112 is installed in thrust mechanism 108.Because the bearing needs to bear double
To axial force, it is necessary to its two ends all carry out axially positions.The inner ring set of angular contact ball bearing 112 is embedded with engagement-seperator
Structure 110.The synchronizing moving of engagement-separating mechanism 110 is driven by angular contact ball bearing 112 when thrust mechanism 108 is moved axially
（Rx directions）.Because engagement-separating mechanism 110 is often contacted, it is necessary to rotate in a circumferential direction with driving neck 13（Ux directions）, pass through angular contact
Ball bearing 112 can realize that engagement-separating mechanism 110 rotates in a circumferential direction independent function.Second axle is installed on thrust mechanism 108
Lid 109 is held, to reach the axially position of angular contact ball bearing 112 and dust-proof effect.The other end of angular contact ball bearing 112 passes through
The shaft shoulder positioning of jump ring 111 and thrust mechanism 108.
Figure 10 is the axonometric drawing of clutch active part.The two ends of return spring 14 are separately mounted to platen 6 and clutch
On lid 2.When the clutch is engaged, return spring 14 is in extended state.Clutch needs separation, and servomotor is inverted, and engagement-
The counter motion of separating mechanism 110, is produced on gap, driving neck 13 axial direction no longer by engagement-separating mechanism 110 with driving neck 13
Thrust.Platen 6 in the presence of return spring 14 with clutch case 2 in the circumferential（Ux directions）Rotate.Drive neck 13 with
Between clutch case 2 along groove direction produce relative motion, drive platen 6 axial movement is separated with friction facing 3, complete from
Clutch separating action.
