1, the petal chuck by a plurality of can form and be installed in one along the movable petal leaves of pto wheel radial be enclosed within on the outer spur gear of pto the end that can take turns along the pto that axially slidably reciprocates of pto; Petal leaves is at the shape that is opened under the spring force pulling function that the flowers are in blossom or circular under the petal chuck collar power effect that is with a plurality of loose collars on its ring, being closed into of driving of spring force and magnetic force, and its effect of a plurality of loose collars that is with on the petal chuck collar is to make the petal chuck collar slide to the intermediate portion in the petal leaves outside more easily; Cover is stuck on the power input shaft wheel accessory whorl external gear during petal leaves closure, and is blocked by the petal chuck collar, thereby makes petal leaves form the power positive drive as internal gear and power input shaft wheel accessory whorl external gear engagement rotation; The separation of clutch: when the electromagnetic coil forward is switched on; The petal chuck collar that electromagnetic attraction makes cover be stuck in petal leaves moves apart petal leaves intermediate portion, the outside and makes petal chuck collar push-and-pull magnetic patch lockplate press close to rotational lock baffle chute piece; Simultaneously; The petal leaves that moves apart the petal chuck collar is drawn outside petal leaves and is opened automatically under the spring tension and petal leaf internal tooth and power input shaft wheel accessory whorl external gear are separated; This moment, the pto wheel made the cone that rubs outside the pto wheel separate with power input shaft wheel accessory whorl internal friction taper hole under the effect of electromagnetic force; And under the electromagnetic attraction effect, make rotational lock baffle plate rotational lock rotational lock baffle chute piece and petal chuck collar push-and-pull magnetic patch lockplate; Thereby it is motionless to pin the pto wheel and the petal chuck collar, and this moment, clutch separation was accomplished, the electromagnetic coil outage; The closure of clutch: when electromagnetic coil is oppositely switched on; Electromagnetism homopolarity repulsion traction makes the rotational lock baffle plate rotate unlock rotational lock baffle chute piece and petal chuck collar push-and-pull magnetic patch lockplate; Thereby make the pto wheel under spring force promotes, shift to power input shaft wheel accessory whorl; And make the pto outer friction of wheel cone snap in power input shaft wheel accessory whorl internal friction taper hole; Simultaneously under the promotion of magnetic force and spring force, pushing the petal chuck collar to petal leaves outside intermediate portion makes petal leaves closed and make in the inboard petal leaf internal tooth of petal leaves and the petal leaf oblique scraping blade snap in power input shaft to take turns the accessory whorl external gear and mesh rotation together; The closed completion of clutch this moment, the electromagnetic coil outage; In the clutch closing course; When petal leaves is taken turns the accessory whorl external gear near power input shaft; Because the pto wheel is inconsistent with power input shaft wheel accessory whorl angular velocity of rotation; Form in the petal leaf of internal serration wheel tiltedly scraping blade earlier near power input shaft wheel accessory whorl external gear and swipe mutually with it by what the same height of multi-disc width successively decreased side by side in order gap discharging at interval; The friction effect that snaps in power input shaft wheel accessory whorl internal friction taper hole with the pto outer friction of wheel cone is the same; The dark gear of oblique scraping blade friction power input shaft wheel accessory whorl external gear in the petal leaf; Make pto wheel angular velocity of rotation progressively near the rotational speed of power input shaft wheel accessory whorl, pto wheel angular velocity of rotation and power input shaft wheel accessory whorl angular velocity of rotation near the time, in petal leaf internal tooth and the petal leaf tiltedly scraping blade just snap in power input shaft respectively and take turns the dark gear and the power input shaft of accessory whorl external gear and take turns the shallow gear of accessory whorl external gear and be engaged with rotation.
2, every petal blade has two to open spring; One is and faces the petal leaf centre bit that the Centromedian petal leaves of petal leaf draws spring fixed column to link to each other outward and just drawing spring; Another root is the petal leaf sense of rotation post-tensioning spring that draws spring fixed column to link to each other outward with the petal leaves that the petal leaves of petal leaves sense of rotation back faces; When the petal chuck collar leaves intermediate portion, the petal leaves outside; Opening spring tension for two opens petal leaves; The effect of petal leaf sense of rotation post-tensioning spring is to make petal leaf internal tooth when separating with power input shaft wheel accessory whorl external gear, has a power identical with sense of rotation to sting the power on petal leaf internal gear teeth to reduce power input shaft wheel accessory whorl external gear; The petal chuck is rotated to an angle, so that dental transition separates with power input shaft wheel accessory whorl external gear easily in the petal leaf of petal leaves to the direction consistent with the petal leaves sense of rotation.
3, two flanks are arranged is the crosslinked wing in petal leaves end to both sides, petal leaves end; The fin of these two fins and adjacent petal leaves is overlapped crosslinked; Promptly a flank of first petal leaves is covered overlapping by a flank of second petal leaves; Another flank of second petal leaves is covered overlapping by a flank of the 3rd petal leaves again; Another flank of the 3rd petal leaves is covered overlapping by a flank of quatrefoil blade again; Another flank that always overlaps onto the N petal leaves is covered overlapping by another flank of first petal leaves, form the annulus as petal, and this annulus can outwards open as blooming; The both wings of all petal leaves are cross-linked with each other with the flank of adjacent two petal leaves all the time and not exclusively separate when opening, and petal leaves can inwardly be closed into the coaxial annulus of pto wheel that is connected with the petal leaf again after opening.
4, all petal leaves afterbodys all have a petal leaves fixedly to wear axis hole; The pto wheel end that connects with petal leaves has the darker notch corresponding with petal leaves; Both sides have two to wear axis hole in the notch; The axis hole of wearing that the petal leaves that has an axle to pass the petal leaves afterbody is fixedly worn axis hole and is fixed in the notch both sides is fixed petal leaves; Make petal leaves do petal leaves open and close action, but the petal leaves afterbody has a petal leaves tailgate, can make petal leaves when receiving the turning effort of power input shaft wheel accessory whorl external gear in the active force of petal leaf internal tooth tooth portion around this rotation; Force transmission to the pto wheel, is rotated thereby drive pto.
5, the petal leaf internal tooth of petal chuck is engaged on power input shaft wheel accessory whorl external gear and rotates together; Can only use with common friction clutch; Because have only common friction clutch make pto wheel and power input shaft wheel set wheel speed near the time; Petal leaf internal tooth could be taken turns the accessory whorl external gear near power input shaft, and then rotates with the engagement of power input shaft wheel accessory whorl external gear, but the petal leaf internal tooth of petal chuck and the engagement of power input shaft wheel accessory whorl external gear are rotated; The efficient of its transmission rotating power will be higher than the transmission efficiency of the friction transmission rotating power of friction clutch, and can prolong the working life of wearing piece in the friction clutch preferably.
6, the big magnet ring of pto wheel afterbody is that heteropole is relatively inhaled placement mutually with the magnetic pole of petal chuck collar push-and-pull magnetic patch and rotational lock plate washer regulation and control magnetic patch; When the electromagnetic coil forward was switched on, the magnetic pole of electromagnetic coil all was that heteropole is relatively inhaled mutually with the magnetic pole of the pto wheel big magnet ring of afterbody and petal chuck collar push-and-pull magnetic patch and rotational lock plate washer regulation and control magnetic patch, carries out the clutch separation action this moment; When electromagnetic coil was oppositely switched on, the magnetic pole of the magnetic pole of electromagnetic coil and the big magnet ring of pto wheel afterbody, petal chuck collar push-and-pull magnetic patch, rotational lock plate washer regulation and control magnetic patch was that homopolarity relatively repels each other, and carries out the clutch closed action this moment.
7, the clutch through coming solenoidoperated cluthes for electromagnetic coil break-make electricity need not reduce the control axostylus axostyle and contact friction loss power with rotation system through direct and rotation system touch controls clutches such as axostylus axostyles like this.
