Such as Fig. 1 to Fig. 3, the following are the principle explanations of linkage unit 6 in the present invention:
Discrete state:, can be smooth by bar magnet 60 when driving link band lower moving guide 61 since bar magnet 60 has magnetism
Guide sleeve 62 is driven to be rotated together, entire linkage unit is rotated in one, i.e., entire linkage unit at this time, still
Bar magnet 60 is not caught in limiting slot so that driving link be only capable of band lower moving guide 61 rotate, linkage unit not by driving link and from
Moving part locking, so that driving link dallies.
Locking state: (fixed guide 61 is interpreted as when relative motion occurs between guide part 61 or guide plate 620
Or guide plate 620, another movement), since bar magnet 60 is between rotation slot inner wall and flat side 610, with guide part 61
Rotation, bar magnet is moved to the edge on flat side 610, and the edge on flat side 610 always squeezes bar magnet 60 on rotation slot inner wall, when turning
When moving limiting slot 64, bar magnet is embedded in limiting slot 64, so that bar magnet 60, flat side 610 and limiting slot 64 constitute a locking
Structure, entire linkage unit no longer individually rotates at this time, but driving link and driven member are carried out locking linkage, so that driving link
It is able to drive driven member synchronous rotation.
The following are the lockings and isolated process of arrangement of clutch in the double acting power drive perambulator of the present invention:
1. the locking state in start-up course: children are sitting on perambulator, and the weight of children drives pedal spindle to press on gravity and leads
To on set 62, so that perambulator, in starting, pedal spindle 1 has one to push the frictional force generated guide sleeve 62, stepped when at this time
Foot pedal drives the rotation of pedal spindle 1 or by driver 2 driving link band lower moving guide 61 is rotated, and guide sleeve 62 is in friction
Stationary state, so that linkage unit 6 becomes locking state from discrete state.
2. the locking state in driving process: when the revolving speed of pedal spindle 1 or driver 2 is greater than the revolving speed at existing power drive end
When, since the effect of the frictional force in accelerator can be amplified, the linkage unit 6 of the bigger side of speed can be by separating
State becomes locking state, therefore the bigger side of relative velocity can be in locking state, the locking time be acceleration moment into
Row locking.
3. the discrete state in driving process: once the larger side linkage unit 6 of revolving speed becomes locking in the moment of acceleration
State, the biggish driving end band motor car wheel speed-raising rotation of speed, the speed of wheel 7 will rise, in the moment that wheel accelerates, make
The lower another party's linkage unit 6 of revolving speed unlocks state, so that bar magnet 60 is returned to medium position by the one end on flat side 610,
When be between the driving link and driven member on wheel speed difference maintain one it is stable at the uniform velocity in when, the position of bar magnet is no longer sent out
The locking of changing, no longer clamping.
