Description
Technical field
The present invention relates to a kind of clutch, in particular it relates to a kind of horizontal eccentric scotch freewheel clutch, it can be answered
For the various fields such as automobile, aircraft.
Background technology
Freewheel clutch is one of widely used mechanical transmission structure part, and it is mainly by the rotation of driving and driven parts
Rotary speed change or the conversion of direction of rotation, and it is automatically obtained clutch function.Existing freewheel clutch mainly has ratchet-type to surpass
More clutch, roller-type overrunning clutch and Wedge type over running clutch.
Ratchet type overrunning clutch mainly includes ratchet, actively ratchet, check pawl and frame etc., and it is by actively ratchet
Movement progress ratchet carry out rotated stepwise.Owing to ratchet type overrunning clutch traverse can only make have level to regulate, ratchet in addition
Sliding on the back of tooth easily causes noise and impact wear, therefore should not be used in high speed situation.
Shown in Figure 1, roller-type overrunning clutch mainly includes inner annular element 102a, roller 103a, outer ring 101a, bullet
Spring 104a and spring set 105a.In its work process, general inner annular element 102a can be as active rotation part, and outer ring 101a is made
For driven revolving part.When in Fig. 1, inner annular element 102a rotates clockwise relative to outer ring 101a, roller 103a is carried by wedging
Dynamic outer ring 101a rotates, and freewheel clutch is in engagement state, and inner annular element 102a rotates jointly with outer ring 101a；Work as internal ring
When part 102a rotates counterclockwise relative to outer ring 101a, roller 103a is retracted into sipes position and is in non-wedging state, surmounts
Clutch separation, inner annular element 102a independently rotates.Such as, in FIG, outer ring 101a is driven and internal ring by another driving means
Part 102a rotating in same direction along clockwise direction, when the rotating speed of outer ring 101a is less than inner annular element 102a, now from relative motion
For relation, inner annular element 102a rotates clockwise relative to outer ring 101a, and freewheel clutch engages the most automatically；On the contrary, if outward
The rotating speed of ring 101a is higher than inner annular element 102a, and now for relative motion relation, inner annular element 102a is relative to outer ring
101a rotates counterclockwise, and clutch is then automatically separated.
Shown in Figure 2, Wedge type over running clutch mainly includes inner annular element 102b, outer ring 101b, voussoir 103b, guarantor
Holding frame 104b and spring 105 etc., wherein the two ends of voussoir 103b are the most concentric circular arc work surface, and these two circular arc work surfaces divide
Do not contact with the raceway arc surface on the raceway arc surface on inner annular element 102b periphery and outer ring 101b inner circumferential.In work process
In, when inner annular element 102b relative to outer ring 101b rotationally clockwise time, frictional force and spring force can trend towards making voussoir
103b is in the counterclockwise direction around its central rotation.Because voussoir size b is more than the radial distance between two raceway arc surfaces, therefore
Voussoir is wedged between inside and outside ring and is locked inside and outside ring and jointly rotates to transmit moment of torsion (i.e. engagement state).If inner annular element
102b can make voussoir relative to outer ring 101b rotate in an anti-clockwise direction, the frictional force between voussoir 103b and inside and outside ring
In a clockwise direction around its central rotation.Owing to size c of voussoir 103b is less than the radial distance between two raceway arc surfaces, wedge
Block can not wedging thus be in the state of getting loose, inside and outside ring can rotate the most freely and not transmit moment of torsion and (i.e. surmount shape
State).
Although freewheel clutch is widely used, but the freewheel clutch of prior art also exists always and cannot overcome for a long time
Technological deficiency.
At present, freewheel clutch whether has obtained extremely being widely applied at civil area or military domain the most.
Since Germany in 1878 uses roller-type overrunning clutch in the changement of " reversing motor ", people are to freewheel clutch
Having carried out the most perfect, up to the present Wedge type over running clutch has become main flow structure.In aircraft industry, helicopter
Main drive chain and accessory drive chain, be both needed between the starter of fixed wing airplane and electromotor use freewheel clutch.At automobile
Industry and other industry are also widely used freewheel clutch.But, freewheel clutch is in the actual application of numerous application scenarios
Effect is unsatisfactory, often results in premature wear.
In general, there is the more serious defect of ratio in the structure of the freewheel clutch of prior art itself, and this structure lacks
Fall into that to cause existing freewheel clutch practical application effect not ideal enough.As it has been described above, ratchet type overrunning clutch traverse can only
Make have level to regulate, apply less.At present mainly with roller and Wedge type over running clutch in practice, run from it
From the point of view of operating mode, there is serious defect in the design of its structure.
Specifically, Fig. 3 and Fig. 4 is seen:
First, the choosing of wedging angle cannot take into account abrasion resistance and moment of torsion transmission performance: Fig. 3 and Fig. 4 all surpasses with Wedge-type
More being shown as a example by clutch, wherein the wedging angle of the voussoir of Fig. 3 is 4 °, and the wedging angle of the voussoir in Fig. 4 is 8 °.For
Those of ordinary skill in the art are it is apparent that the least then wedging performance in wedging angle of voussoir is relatively preferable, but voussoir 103b therewith
For bearing effective frictional layer minimizing of abrasion, abrasion resistance is deteriorated, and this can make the working life of voussoir reduce.If increase wedge
Closing angle, although effectively frictional layer is increased, abrasion resistance strengthens, but wedging performance weakens relatively, and this can cause overdrive clutch
The core technology index moment of torsion load-carrying properties of device significantly reduce.
Second, there is major defect in the force structure of moment of torsion transmission: the freewheel clutch of prior art, either roller
Freewheel clutch or Wedge type over running clutch, there is serious limitation in the thinking of its structure design, surpassing in these types
More in clutch, either surmount state or engagement state, roller or voussoir and be required to keep and outer ring and inner annular element
Contact, changes operating position can respond the relation that relatively rotates between inner annular element and outer ring by friction, this rubs
The existence of wiping state had both required that roller or voussoir can change operating position neatly, required that again frictional force is not when surmounting state
Outer ring should be significantly impacted rotate with inner annular element independence relative to each other, it thus appear that roller and voussoir need to keep phase
To less contact size, but in the engaged condition, outer ring and inner annular element need to be passed by the wedging of roller and voussoir
Torque delivery is so that outer ring and inner annular element associated movement, and roller or voussoir that this size is less are obviously difficult in wedging state
Transmit bigger moment of torsion.It is to say, in the freewheel clutch of this prior art, roller or voussoir need to realize self work
Making adjustment function and the wedging function of position, this structure mentality of designing determines roller and can only use with voussoir relative light
Structure, the practical situation of the freewheel clutch of prior art just so, when wedging duty, roller or voussoir interior,
Contact wedging face between outer ring is all the time in narrow line contact face or be similar to line contact face and (may be considered generally
Line contact, sees position A and B in Fig. 3 and Fig. 4), even if the suffered pressure of this contact condition has been in the load of maximum
State, it is possible to the frictional force of generation is also limited, common rotation between inside and outside ring and when needing transmitting large torque,
Usually produce skidding between inside and outside ring, even cause voussoir or roller seriously to damage, cause security incident.This not
Meet " high load with small power " force status of Laws of Mechanics, be roller and the insoluble defect of Wedge type over running clutch.
Above 2 points, limit the moment of torsion bearing capacity of existing freewheel clutch, have been greatly reduced making of freewheel clutch
With the life-span so that use the functional reliability of the equipment of freewheel clutch and serviceability to significantly reduce.
Because the said structure defect of prior art freewheel clutch, need to design a kind of novel freewheel clutch,
With the shortcoming overcoming prior art.
