Detailed description of the invention
Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 are the partial structure diagrams of clutch different embodiments of the present invention.
Specific embodiment
It is as follows in conjunction with attached drawing clutch embodiment of the invention:
A kind of clutch, including driving part and slave unit, be connected on driving part and/or slave unit multiple groups from Mechanism is closed, clutch connects elastomeric element and/or synchronous circle, and every group of clutch includes friction block 5 and kinematic link 6, is rubbed Synchronization mechanism is equipped between cleaning block 5.Fig. 1 show the structure that clutch is connected on driving part, driving part, that is, inner ring 1, slave unit, that is, outer ring 2, clutch includes friction block 5 and kinematic link 6, and the two constitutes flexible connection in hinged way, The other end of kinematic link 6 is flexibly connected by hinge hole 7 with the composition of inner ring 1, and in order to balance radial force, clutch is at least 2 groups, and organize number it is more when, it is more uniform to the stress of inner ring 1 and outer ring 2.The two sides of inner ring 1 are additionally provided with the fixed side plate of screw 3, for the axial limiting of outer ring 2 and clutch, side plate 3 is equipped with oil leak hole 4.Clutch connects elastomeric element, elasticity Component, that is, cup spring 8, groove 9 is provided on friction block 5 can hold all friction blocks 5 in inner ring 1 tightly for connecting cup spring 8, cup spring 8 On.According to the above, clutch of the invention works in this way:When drive inner ring 1 rotate after, if clutch from Cardianeuria is to overcome the enclasping force of cup spring 8, then clutch is from state, when the centrifugal force that revolving speed improves clutch overcomes ring After the enclasping force of spring 8, friction block 5 is flared out and the inner faces contact with outer ring 2, at this moment, if the tilt angle of kinematic link 6 It then can directly drive outer ring 2 to constitute transmission less than friction self-locking angle, but shock loading and pause and transition in rhythm or melody can be brought, if kinematic link 6 Tilt angle be greater than friction self-locking angle then may make up half-clutch transmission, when revolving speed persistently increases, the centrifugal force of clutch is not Disconnected to increase after applying enough normal force, inner ring 1 and outer ring 2 will transition to Synchronous Transmission and urge the clutch into conjunction state. When controlling the state of clutch using cup spring 8, clutch of the invention is functionally similar to existing centrifugal clutch, But difference is in the present invention, and centrifugal force is mainly used to control clutch and it is made to meet friction self-locking condition, rather than straight It connects for being driven.On the basis of above structure, if removing cup spring 8, if compressed spring is connected between adjacent clutch It may make up the freewheel clutch of general function.Clutch, which also can connect, synchronizes circle 13 without elastomeric element, Huo Zhetong When connection elastomeric element and it is synchronous enclose 13.Referring to fig. 2, the two sides of friction block 5 are connected with synchronous circle 13, and synchronous 13 sets of circle is in side plate In arc groove on 3, synchronous circle 13 is equipped with pilot hole 12 and is correspondingly connected with the guide head 14 being arranged on friction block 5, uses third Square mechanism rotation synchronizes the radial position of changeable clutch after circle 13, that is, changes the clutch state of clutch.Referring to figure 1, it is equipped with synchronization mechanism between friction block 5, the groove 9 and convex block 11 of 5 side of synchronization mechanism, that is, friction block, on adjacent friction block 5 Groove 9 and convex block 11 can cooperate composition limit, groove 9 and convex block 11 can also be substituted with hole and pin.Synchronization mechanism Effect is to make the holding of friction block 5 keep strokes to prevent from being freely rotated, and can guarantee that the gap between friction block 5 and outer ring 2 is uniform, Be conducive to film distribution in lubricating status, synchronization mechanism can also be such that the stress of clutch and abrasion homogenizes and improve vibration resistance Can, it will be clear that synchronous circle 13 among the above is because equally have synchronizing function, therefore it is also assumed that be a kind of synchronization Mechanism can not need setting groove 9 and convex block 11 on friction block 5 after enclosing 13 using synchronization.Fig. 3 show inner ring 1 and outer ring 2 On be all connected with the structure of clutch, clutch and connection type are identical, and cage ring is equipped between two kinds of clutches 15 prevent friction block 5 from directly contacting, and cage ring 15 can use the arc groove limit on side plate 3.The characteristics of this clutch configuration is Cage ring 15 is killed and cannoted rotate relative to each other by the clutch holding connected on outer ring 2 when low speed, when outer ring 2 is led to by inner ring 1 It crosses cage ring 15 to drive after revolving speed persistently increases, the clutch connected on outer ring 2 is gradually flicked due to centrifugal force increase, can Release and half entered from state to the braking of cage ring 15, this clutch need persistently to drive outer ring 2 just can be completely transformed into from State, have tri-state variation characteristic, can be applied to it is multiple cooperation have differential under conditions of work.Obviously, according to the structure of Fig. 3 It is easy to derive the structure that clutch is connected on only outer ring 2, it can be from static to setting behind this clutch driving outer ring 2 Determine to be in conjunction state in revolving speed section, and the structure of Fig. 1 or Fig. 2, clutch can be made from setting speed to restriction after driving inner ring 1 Conjunction state is in maximum speed section.
According to the above, clutch advantage of the invention is that part category is less, and structure is more compact small and exquisite, clutch Structure acts synchronous uniform force using low secondary connection, thus can bear certain shock loading and transmit biggish power with Torque can gradually lose half-clutch state after clutch abrasion but can still be driven, in addition, clutch uses different structure Or when combined application, theoretically clutch can be arbitrarily automatically controlled by rotation speed change in full speed section.
The following are the preferred embodiments of clutch configuration of the present invention:
Elastomeric element is cup spring 8.When using cup spring 8 as elastomeric element, clutch can be made voluntarily to control with rotation speed change Clutch.The advantages of cup spring 8 is that length is longer not easy to fatigue, and force variation is insensitive, is conducive to set and stablize turning for clutch Fast parameter.Cup spring 8 can also be substituted with O-ring etc..
Groove 9 is provided on friction block 5, cup spring 8 is placed in groove 9.The groove 9 that cup spring 8 is placed on friction block 5 can also It is arranged in side.
Side plate 3 is connected on driving part and/or slave unit.Side plate 3 can be fixed on driving part or slave unit, When structure difference, driving part and slave unit can be separately connected side plate 3.Side plate 3 is used for inner ring 1, outer ring 2 and clutch Between axial limiting, and play protection and change lubrication state the effects of.Side plate 3 and driving part or slave unit may be used also The flexible connection that can be moved axially is constituted, when the third-party institution applies axial force on side plate 3, can compress clutch makes It fails, or the third-party institution is arranged on side plate 3 and can control synchronous 13 rotation of circle, thus it is possible to vary the clutch shape of clutch State.
Cage ring 15 is equipped between driving part and slave unit.Cage ring 15 is used for structure shown in Fig. 3, i.e. inner ring 1 It is all connected with clutch on outer ring 2, if without cage ring 15, after the oscillating stroke limit of two kinds of clutches, directly Contact also may be constructed transmission, due to being difficult to ensure the circularity of contact surface, can lose face contact characteristic and clutch is caused to hold It is easy to wear.
Multiple groups clutch is divided into positive clutch group and reversed clutch group, and positive clutch group and reversed clutch group constitute series connection Structure.Fig. 1, Fig. 2, clutch configuration shown in Fig. 3 have unidirectional characteristic when transmission, to constitute Bidirectional driving, can be connected in series It is added reversed clutch group, the braking direction of positive clutch group and reversed clutch group is equivalent to two on the contrary, structure as shown in Figure 4 The clutch of a Fig. 3 structure removes side side plate 3, the construction to merge into a single whole after series connection.Positive clutch group and reversed clutch group Also it can be used parallel-connection structure, i.e. in structure shown in Fig. 1 or Fig. 2 or Fig. 3, appropriate adjustment structure is by several clutches therein Reversed installation, major defect are to bring difficulty to the synchronization of friction block 5 and the connection of elastomeric element.Structure shown in Fig. 4, just To clutch group and reversed clutch group using may make up a kind of Dan Heshuan clutch after different clutch parameters, can turn in different In number interval, it not only can behave as unidirectional characteristic but also can behave as bidirectional characteristic, such as:Set the revolving speed area of positive clutch assembled state Between be C-F, the revolving speed section of reversed clutch assembled state is D-E, C < D < E < F, in this way in C-D and E-F revolving speed section just It can make clutch that there is unidirectional characteristic, there is bidirectional characteristic in D-E revolving speed section.
Friction block 5 includes friction plate 16 and free bearing 17, and the two constitutes inclined-plane 19 and is cooperatively connected.Clutch of the invention is recommended It works under lubricating condition with half-clutch state, service life depends on the wear allowance of friction block 5.Due to lubricating condition The coefficient of friction of lower current material is generally smaller, causes the angle change of clutch more sensitive to abrasion, this can be to transmission Characteristic brings larger impact to shorten the service life of clutch, solution first is that increasing the length of kinematic link 6 in engineering Degree carrys out increased wear surplus, but the radial dimension of clutch can be made larger not satisfactory.If friction block 5 shown in FIG. 1 divided Solution is friction plate 16 shown in fig. 5 and free bearing 17, and the two constitutes the flexible connection that axial slope 19 cooperates, then can have abrasion to mend Repay function.There is compressed spring 20 between friction plate 16 and free bearing 17, the two can be made to maintain axial movement power, set on friction plate 16 Being equipped with friction head 18 can contact with the inner radial surface of outer ring 2.The compensation mechanism that Fig. 5 structure uses, its main feature is that 18 He of friction head Driving face on friction plate 16 has synchronizing characteristics, i.e. 18 excessive wear of friction head causes compensation rate excessive, meeting when driving contact Keep the tilt angle of clutch excessive, the section of half-clutch state increases, and can synchronize the abrasion of aggravation driving face, on the contrary then same Step reduces.
Side plate 3 is equipped with centrifugal-block 24, the synchronous circle 13 of the connection of centrifugal-block 24.Referring to Fig. 6, side plate 3 on clutch with it is interior Circle 1 is fixedly connected, and radial groove is provided on side side plate 3, centrifugal-block 24 and balancing spring 23 are connected in sliding slot, is centrifuged Sliding block 22 is hinged on block 24, the angle 21 being arranged on the circle 13 synchronous with side of sliding block 22 is cooperatively connected.When clutch enters conjunction After state, if 1 revolving speed of inner ring persistently increases, the centrifugal force of centrifugal-block 24 constantly increases, and synchronous circle can be driven by sliding block 22 13 rotations separate clutch with outer ring 2.It is tri-state that the clutch of this structure, which also has the difference of tri-state characteristics and Fig. 3, Change it is unrelated with outer ring 2, the disadvantage is that clutch characteristics can be associated with more parameters, including centrifugal-block 24, balancing spring 23 and Angle 21 etc. can make the clutch become controlled architecture when centrifugal-block 24 is using the third-party institution's such as hydraulic-driven.In Fig. 6, Clutch uses the structure shown in fig. 5 with compensation function, due to having used synchronous enclose 13 as synchronization mechanism, at this moment The friction head 18 being arranged on friction plate 16 also has the function of guide head 14 in Fig. 2.
There can be more drive characteristics using clutch of the invention after preferred embodiment, constitute Dan Heshuan clutch Afterwards, an important use is on step change transmission as automatic gearshift.
It is the embodiment of speed changer of the present invention below:
A kind of speed changer is step change transmission, including at least one set of wheel for inputting group and one group of output wheel group, wheel for inputting group With or output wheel group on gearshift use above-mentioned clutch.Speed changer of the invention is improved on the basis of existing, nothing By being using gear, sprocket wheel etc., basic structure includes that the installation of clutch and wheel group is connected as well-known technique or common sense, therefore has Body embodiment is no longer described in detail.
Shift of transmission scheme of the invention or process are summarized as follows:
If the revolving speed section of low range clutch conjunction state is A-B, the revolving speed section of high gear clutch conjunction state is C-D, is shown It so, is theoretic seamless combination state as B=C, what this did not accomplished almost in practice, and will appear biography as B < C It is dynamic to interrupt scheme that is not satisfactory, therefore being only left B > C, that is, there is clutch overlapping region.It wants to move certainly in clutch overlapping region Gear, high to low gear clutch all must have single-direction transmission characteristic, the Dan Heshuan clutch mentioned among the above, when for shifting gears its Meaning is:In clutch overlapping region, gear is automatically selected using mono-directional overrun characteristic, revolving speed raising is then switched to high tap position, Decline is then switched to low-grade location, after revolving speed leaves overlapping region, further constitutes bi-directional braking.When load drives former move Because positive clutch group failure, it is out of stock that downshift process can make clutch overlapping region that can show as, and passes through the parameter of clutch when machine Design can make region out of stock as small as possible, but still stay enough spaces for reasons of safety, and no person once occurs It is unexpected to constitute bi-directional braking in clutch overlapping region, transmission may be made to be badly damaged.
Speed changer of the invention can voluntarily switch gear, can reflect the power or torque characteristics of prime mover with rotation speed change And load characteristic carries out suitable tune to prime mover output power, is conducive to control clutch as necessary by some sensor feedbacks Situation and the abrasion for reducing clutch.When speed changer needs the functions such as slope road downshift, trip stop transmission, third party's machine can be used Structure controls the side plate 3 on corresponding clutch or synchronizes circle 13 to realize.
The great advantage of speed changer of the present invention be can the self shifter in the case where not turning off power and continuous acceleration and deceleration, When transmission silk floss pass through it is without cease improve accelerating ability, execute gear shift operation since electronic control unit can not needed, advantageously reduce Cost simultaneously improves transmission efficiency and reliability.
