The content of the invention
The present invention proposes a kind of centrifugal clutch, the technical problem to be solved in the present invention be how to propose different structure and
It is suitably applied in the centrifugal clutch in gear-shifting wheel hub motor.
The present invention proposes a kind of gear-shifting wheel hub motor, the technical problem to be solved in the present invention be how to propose it is another
Plant the gear-shifting wheel hub motor of structure.
The technical problem to be solved of the invention can be realized by following technical proposal：This centrifugal clutch is included actively
Part and the driven member being set in outside driving link, are provided with the centrifugation body that can be radially slided along driving link and can make centrifugation body in driving link
The first spring for resetting；The driver plate that can be circumferentially slided along driving link, the outside of driving link are at least provided with the side of driving link

The commutation drive mechanism that when body being centrifuged and radially sliding driver plate can be made circumferentially to slide is provided between body and driver plate.
When driving link rotates, centrifugation body produces centrifugal force, the elastic force of the first spring is overcome, to the outer radial of driving link
Slide, centrifugation body drives driver plate circumferentially to slide by the drive mechanism that commutates, driver plate drives limited post movement, realize release rolling
Post；Roller is moved under the elastic force effect of second spring.When the rotating speed of driving link is less than centrifugal clutch combination rotating speed, due to
Centrifugation body produces centrifugal force smaller, and centrifugation body radially slides stroke deficiency, causes driver plate circumference sliding stroke and roller to move
Stroke is not enough, and then roller cannot dally with driven member and driving link frictional engagement, i.e. driving link simultaneously.When the rotating speed of driving link
During higher than centrifugal clutch combination rotating speed, because centrifugation body produces centrifugal force increase, centrifugation body radially slides stroke increase so that
Roller shift motion also increases, so roller simultaneously with driven member and driving link frictional engagement, force driven member enter rotate shape
State and realize transmitting torque.
When centrifugal clutch is in bonding state, stop to driving link input power, elastic force of the centrifugation body in the first spring
To the radially slip of driving link under effect, realize resetting, centrifugation body drives driver plate circumferential anti-by the drive mechanism that commutates
To slip, driver plate drives limited post to move, and promotes roller movement, roller is tied with driven member and driving link friction simultaneously
Close, and then realize that centrifugal clutch is separated.
The kind of drive of this centrifugal clutch and combine and separate control mode unlike the prior art.This be centrifuged from
The combination rotating speed of clutch can determine that such as the rotating speed of driving link is 280 revs/min according to design；When the driving link of this centrifugal clutch
When rotating speed is less than rotating speed is combined, no matter driving link forward or reverse is idle running, and this state meets gear-shifting wheel hub motor and leads to
Output and gear-shifting wheel hub motor after reducing gear slows down is crossed to reverse；Roller is not rotated during this state, is significantly reduced
Roller wear, and then considerably improve the service life of roller so that the service life of centrifugal clutch meets gear-shifting wheel hub
The technical requirements of motor.When the driving link rotating speed of this centrifugal clutch is higher than rotating speed is combined, centrifugal clutch is in knot
Conjunction state, centrifugal clutch realizes equispeed output and transfer of torque meets gear-shifting wheel hub motor at a high speed and efficiently output will

Property.
Being provided between centrifugation body 1c and driver plate 1d can make what driver plate 1d was circumferentially slided when body 1c being centrifuged and radially sliding
Commutation drive mechanism.Commutation drive mechanism includes the commutation post 1c1 being connected as a single entity with centrifugation body 1c and on driver plate 1d
Skewed slot 1d1, in commutation post 1c1 insertion skewed slots 1d1.When centrifugation body 1c is radially slided relative to driving link 1a, commutation post 1c1 compels
Driver plate 1d is set to be rotated relative to driving link 1a.There is circular orientation portion 1a4, driver plate 1d to be set in ring at the middle part of driving link 1a
Formed on the 1a4 of shape location division, between the inner face of driver plate 1d and the circular orientation portion 1a4 lateral surfaces of driving link 1a and be oriented to knot
Structure, and then driver plate 1d can stablize and neatly rotate.
By the cohesive process, bonding state and the separation process that illustrate centrifugal clutch 1 further illustrate this be centrifuged from
The effect of all parts and advantage in clutch 1：
Direction shown in arrow rotates and is gradually increased until that rotating speed exceedes centrifugal clutch 1 in driving link 1a is along Fig. 3
During with reference to required rotating speed, centrifugation body 1c produces centrifugal force and gradually increases, and centrifugation body 1c is slided to the outer radial of driving link 1a,
First spring 1e is gradually compressed；In the process, centrifugation body 1c drives commutation post 1c1 synchronizing movings, commutation post 1c1 to force biography
Dynamic plate 1d is rotated relative to driving link 1a, and driver plate 1d rotational travels can be slided by skewed slot 1d1 angles of inclination and centrifugation body 1c
Stroke Control；Driver plate 1d drives limited post 1k synchronizing movings, i.e. limited post 1k to be moved to away from wedge-shaped slot 1a1 bottom surfaces direction,
Second spring 1j promotes roller 1f also to be moved to away from wedge-shaped slot 1a1 bottom surfaces direction；Top and driven member due to wedge-shaped slot 1a1
Spacing between the bottom of wedge-shaped slot 1a1 and driven member 1b medial surfaces is smaller than between 1b medial surfaces, roller 1f moves a spacing
From rear, roller 1f both with driven member 1b medial surface rolling friction, and with the plate face rolling friction of backing plate 1g, and then drive driven member
1b is rotated；Moment roller 1f afterwards can further be moved and be formed self-locking, i.e. roller 1f and driven member 1b medial surfaces and backing plate
The equal static friction of plate face of 1g is combined, and driving link 1a drives driven member 1b efficiently to rotate by roller 1f, and can be transmitted suitable electronic
The torque value that car is formed.
When the rotating speed of driven member 1b is more than the rotating speed of driving link 1a, driven member 1b drives roller 1f near wedge-shaped slot
Move in 1a1 bottom surfaces direction so that roller 1f back switches to the plate face rolling friction shape with driven member 1b medial surfaces and backing plate 1g
State.And when rotating speed needed for driving link 1a rotating speeds are combined less than centrifugal clutch 1, centrifugation body 1c makees in the elastic force of the first spring 1e
Gradually resetted under, that is, body 1c is centrifuged and is gradually slided to the center position of driving link 1a；In the process, centrifugation body 1c bands are moved
To post 1c1 synchronizing movings, commutation post 1c1 forces driver plate 1d to rotate backward, and then driver plate 1d drives limited post 1k synchronously to move
Dynamic, i.e. limited post 1k is moved near wedge-shaped slot 1a1 bottom surfaces direction, and limited post 1k promotes roller 1f near wedge-shaped slot 1a1 bottoms
Face direction is moved, and second spring 1j is gradually compressed.
Direction shown in arrow reversely rotates and speed is less than needed for the combination of centrifugal clutch 1 in driving link 1a is along Fig. 3
During rotating speed, centrifugal clutch 1 is in released state all the time.
When this centrifugal clutch 1 is in released state, roller 1f is located in locating slot 1i, i.e. roller 1f will not be with driven member
1b is contacted, and will not more produce rolling, thus significantly reduces roller 1f rolling durations, and then is effectively guaranteed centrifugation clutch
