There are 2 pieces of disc 23 to be enclosed on reducing wheel shaft, 2 pieces of disc 23 can also link into an integrated entity structure and constitute
There are multiple notches 24 to be used to place slide 21 on spoke wheel, disc 23.Driving-chain is included by multiple chains
Section head and the tail are hinged the chain body of composition, and chain link is formed by fixedly connecting by 2 trundles 1 and free bearing 4,
Being cased with fixing on trundle 1 has hinge face 5 outside at 2 on connecting rod 2, each free bearing 4, outer hinge face 5 is used
In being hinged kinematic link 7, the position in outer hinge face 5 corresponds at the axis of trundle 1, can make chain link
Side load is preferably born, multiple chain links are hinged composition transmission using multiple connection head and the tail of connecting rod 3
The chain body of chain is used to bear to pull to load.Driving-chain and/or diameter-changing wheel are provided with multiple flexible connections
Brake pad and the mechanism for controlling brake pad, i.e. brake pad can be only connected on driving-chain, or
It is only connected on diameter-changing wheel, or brake pad is all connected with driving-chain and diameter-changing wheel, shown in Fig. 1
A kind of embodiment on driving-chain is only connected to for brake pad.Referring to Fig. 1, brake pad includes friction
Piece 10, the structure of friction plate 10 is similar to the free bearing 4 on chain link, and chain is connected to by kinematic link 7
The both sides of section, use outside at 2 on 2 each free bearings 4 of the correspondence of kinematic links 7 per side and cut with scissors face 5,
Kinematic link 7 is constituted with friction plate 10 and free bearing 4 and is hinged respectively using interior hinge face 9；Kinematic link
The minimum and maximum pendulum of kinematic link 7 can be limited by having on 7 after multiple chains of command 8, reasonable design parameter
Angle, to prevent friction plate 10, kinematic link 7 and free bearing 4 from separating, friction plate 10 and free bearing 4
Between be connected with connecting rod piece 11.With reference to described above, transmission process of the present invention is such：Work as biography
When dynamic chain is straight condition, the mechanism of control brake pad will be rubbed by changing the pivot angle of kinematic link 7
Pad 10 is drawn in, friction plate 10 is passed in and out diameter-changing wheel without being contacted with disc 23, when
After driving-chain is wrapped on diameter-changing wheel and bent, the mechanism of control brake pad can discharge friction plate 10
And apply pretightning force and be allowed to contact composition frictional drive with disc 23, according to friction self-locking principle, only
Will the angle of inclination of now kinematic link 7 be less than the friction self-locking that friction plate 10 and disc 23 are constituted
Angle, the frictional drive is reliable and will not skidded.Referring to Fig. 1, the mechanism bag of brake pad is controlled
The pretension shell fragment 6 being fixed on free bearing 4 is included, is connected on adjacent friction plate 10 and pushes connecting rod 12 to
With pull to connecting rod 13, pretension shell fragment 6, which is pressed on the side of kinematic link 7, remains friction plate 10
Trend is flicked, pushes connecting rod 12 to and pulls to the link position of connecting rod 13 respectively positioned at chain link jointed shaft
The upper and lower of line, pushes connecting rod 12 to and pulls to connecting rod 13 to be connected with friction plate 10 using waist-shaped hole；
When chain body is stretched, push connecting rod 12 to and pull to connecting rod 13 adjacent friction plate 10 is pushed to respectively
With pull to position-limiting action, friction plate 10 can not be flicked, and after chain body is bent, push the He of connecting rod 12 to
The waist-shaped hole pulled on connecting rod 13 loses position-limiting action due to there is free travel, at this moment friction plate 10
It can be flicked by pretension shell fragment 6.Using pushing connecting rod 12 to and pulling to after connecting rod 13, only work as friction
Friction plate 10 is just allowed to flick after the connection connecting rod 3 of the both sides of piece 10 is all bent, therefore pushes connecting rod to
12 may be considered a kind of twin controlling organization with connecting rod 13 is pulled to, and advantage is can be completely in cornerite
In the range of control friction plate 10 action.There are friction means to constitute mutually on driving-chain and diameter-changing wheel
Face is contacted, according to described above, in the embodiment shown in fig. 1, the friction means on driving-chain
For friction plate 10, the friction means on diameter-changing wheel are disc 23, the side of friction plate 10 and disc
Sagittal plane on 23 may make up face Contact Transmission.Because band linked transmission its process is necessarily from master
Driving wheel arrives driven pulley again to driving-chain by driving-chain, when brake pad is only connected to driving-chain or biography
When on driving wheel, to ensure that driving wheel and drive can drive mutually, it is necessary to there is incline direction opposite
Multiple kinematic links 7 connect brake pad, in the driving-chain shown in Fig. 1, in adjacent link
Its oblique angle of kinematic link 7 it is in opposite direction.In the above-described embodiment, friction plate 10 can also lead to
Cross inclined-plane to be connected directly between on the free bearing 4 of chain link, this structure is the simplest, but to meet friction
The material of condition of self-locking, free bearing 4 and disc 23 must be different, and relative to friction plate 10, no
Size with coefficient of friction decides the size at inclined-plane oblique angle, therefore is limited by material, uses inclined-plane
To be that oblique angle is difficult to larger for major defect during connection, and this can bring all to processing and manufacturing, transmission process etc.
Many disadvantages.
It is a kind of embodiment that brake pad is all connected with driving-chain and diameter-changing wheel shown in Fig. 2,
On diameter-changing wheel, brake pad is connected on slide 21.If removing disc 23 in Fig. 1 makes brake pad
Directly contacted with the sagittal plane of slide 21, remove all brake pads on driving-chain, same energy in Fig. 2
It is enough to realize transmission, but ' killing ' phenomenon can be produced, i.e., in speed regulation process, between slide 21
Distance can change and drive brake pad to move, if its self-locking direction of the brake pad being driven is not
It is same both to be caused to contradict each other and hinder speed governing to carry out.In Fig. 1, disc 23 can block slide
21 drive brake pad to move, in fig. 2, its inclination of all brake pads on driving-chain and diameter-changing wheel
Direction is consistent, i.e. the self-locking direction of brake pad is all identical, and both means can solve ' to sting
Extremely ' problem.Between brake pad on embodiment shown in Fig. 2, driving-chain and diameter-changing wheel mutually
Composition face is contacted, and necessarily having a kind of brake pad in transmission can be compacted, and this process can increase
Friction block self locking stroke reduces transmission efficiency, can be using two kinds of brake pads in radial direction position in structure
Put and stagger the method that avoids direct contact with to improve.Fig. 2 structure can only make drive towards specific
Direction, which rotates, to be driven by driving-chain mutually.
The following is the explanation to further alternative of the invention：
The diameter-changing wheel includes cone pulley and slide.It is reducing using cone pulley 22 and the structure of slide 21
A kind of ideal embodiment of wheel, can bear big axial force, because the effect of cone pulley 22 is
Change the radial position of slide 21, therefore can be substituted with linkage.
The diameter-changing wheel is provided with disc.One of main function of disc 23 is prevented when being speed governing
' killing ' phenomenon, has the disadvantage to make the axial dimension of diameter-changing wheel to become big, and meeting and biography during speed governing
Dynamic chain produces radial displacement.
The slide is provided with the brake pad being flexibly connected.When slide 21 is provided with rubbing for being flexibly connected
After cleaning block, the embodiment with reference to shown in Fig. 2 is prevented ' killing ' when main function is speed governing
Phenomenon.
The side of the driving-chain, which is additionally provided with friction chain, friction chain, friction means and elastomeric element.
Referring to Fig. 3, the side of driving-chain refers to the lateral surface of width, when driving-chain is enclosed on diameter-changing wheel
When, friction chain constitutes sagittal plane with diameter-changing wheel and contacted, and slide 21 can be blocked directly to be contacted with brake pad.
The chain that rubs can use the frame mode of chain body in above-mentioned driving-chain, i.e., using chain link 15 and connection connecting rod
16 head and the tail are hinged composition, and chain link 15 is the friction means on friction chain, the elasticity that friction chain is provided with
Part is the steel band 17 being embedded on Internal and external cycle.To realize that transmission must is fulfilled for two after increase friction chain
Condition：First, the distance between friction means must be variable on friction chain, and second, slide 21,
Pretension frictional force between brake pad and friction chain must be able to overcome the spacing of friction means on friction chain
From resistance when changing, therefore friction chain is hinged by rigid element when constituting, and is enclosed on drive just not
Can there are straightway, i.e. pitch length to have to be larger than theoretic minimum length.Elastomeric element steel band 17
Can make friction chain keep certain shape as close to it is oval or it is avette avoided straightway, the chain that rubs makes
The distance change for being deformed to adjust friction means with steel band 17 meets transmission and requires that major advantage is to rub
Composition can be hinged with rigid element by wiping chain main body, can solve it is above-mentioned in ' killing ' problem for mentioning,
At this moment extension of the friction chain equivalent to the structure of diameter-changing wheel superradial 23 in Fig. 1.Due to friction means
The variable such friction chain of required distance is not subject to pull to load, therefore the connection connecting rod 16 on friction chain
It can be substituted with compliant members such as springs, this structure may be used in the embodiment shown in Fig. 2.
After increase friction chain, brake pad is necessarily connected with driving-chain, at this moment brake pad is also attached to and rubbed
Wipe on chain.
The friction chain is different with the pitch length of chain body.Driving-chain shown in Fig. 3 is structurally characterized in that
Side in the direction of the width, the incline direction of all brake pads is consistent, and other side is all
Brake pad incline direction is also consistent, but is reversed dip.When driving-chain increase friction chain after and make to rub
Wipe chain different with the pitch length of chain body, chain body and friction chain are leaving drive cornerite model during transmission
Different speed are had after enclosing, this differential motion can have to the brake pad shown in Fig. 3 on driving-chain
There is unblock effect, so the elasticity of pretightning force only can need to be applied with the mechanism of simplify control brake pad
Component, at this moment, another effect of steel band 17 is increase width on above-mentioned middle friction chain
Bending resistance, friction chain leave drive after prevent from excessively being flicked by brake pad.When friction chain
When the self-locking and unblock of brake pad are controlled using differential motion, it is believed that friction chain is controlling organization
A part.Increase friction chain and after friction chain and chain body have differential structure, it is bootable to rub
Cleaning block passes in and out drive in the case of being contacted all the time with friction chain, self-locking when substantially increasing transmission
Response speed, the self-locking of brake pad and releasing process can accomplish seamless automatic switchover, make driving-chain more
It is adapted to high-speed drive.In embodiment shown in Fig. 3, because driving-chain lateral force mode is not right
Title can bring some unfavorable problems, need to further be improved in structure.
Present invention also offers a kind of buncher, the buncher uses above-mentioned driver
Structure.
The transmission mechanism of the present invention, the layout of structure, brake pad when driving-chain and diameter-changing wheel and control
Mechanism processed can not derive kinds of schemes on an equal basis, and such as driving-chain chain body can use belt or pushing-type knot
Disc 23 on structure, diameter-changing wheel can be controlled to separate and contact with brake pad with incline structure, separately
Outside, the present invention can further simplify knot using ' killing ' phenomenon will not occur when surmounting transmission
Structure.
The transmission mechanism of the present invention uses chain return mode, can be prevented using friction self-locking principle during transmission
Only driving-chain skids, therefore with higher transmission efficiency, in addition, the present invention realizes rigid element
The kind of drive contacted using face, breaching material limitation has the advantages that transmission moment of torsion is big.This hair
Bright transmission mechanism is mainly used in constituting buncher.
