Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention will be further described, but not as a limitation of the invention.
Fig. 1 to Fig. 3 illustrates a kind of example of the present invention, comprises input gear 1, rotating shaft 2, fork controls dish 3, output gear 4, roller 5, damping device 7, spring sheet 6.
Described input gear 1 one sides have step hole 104, have four along the circumferential direction uniform arc grooves 101 that are used for holding roller 5 on described step hole 104, and described arc groove 101 is connected with step hole 104 by the transition camber line 102,103 of both sides; Described fork controls dish 3, for the circular step 301 with center hole with the disk 303 in identical central hole, has 4 grooves 302 that are used for holding roller 5 on described circular step 301; Described output gear 4 one sides have external diameter to be less than the circular step 401 of root circle; This circular step 401 can the center hole of gapped insertion fork controls dish 3 in, circular step 301 can gapped insertion step hole 104 in, wherein the position of groove 302 is corresponding with arc groove 101; 4 cylindrical rollers 5 are arranged in the space that groove 302 and arc groove 101 and circular step 401 form; The corresponding groove of circular step 301 302 inner sides, position are furnished with circular arc spring sheet 601,602 accordingly, spring sheet 601,602 symmetries be arranged in groove 302 center line both sides, spring sheet major part is fixed on circular step 301 inner sides, fraction exposes at groove 302, and spills the half of part less than groove 302 width; Disk 303 outsides are furnished with 4 along the circumferential direction uniform damping devices 7, and damping device outside 701 is fixed with frame (not shown), and 702 surfaces that are held in disk 303, damping device inner side provide frictional damping.
The working procedure of above-mentioned example is: under state of rest, whole clutch is in position as shown in Figure 2, when driving input gear 1, electric machine rotation rotates along a direction, due to the surface friction drag of damping device 7, fork controls dish 3 can not be followed at once input gear 1 and be rotated, input gear 1 and fork controls dish 3 produce relative rotation, as shown in Figure 3, roller 5 detaches arc groove 101, a bit tangent with transition camber line 103 on roller 5 circumference, another point is tangent with groove 302 sidewalls, along with increasing in relative rotation, roller 5 extrusion spring sheets 601, 602 distortion, and then inwardly lock circular step 401, now the surface friction drag of damping device 7 no longer can limit the rotation of fork controls dish 3, input gear 1 will drive fork controls dish 3 and output gear 4 rotating in same directions, and then complete the control of motor to output terminal, in like manner, in the time that motor drives input gear 1 to rotate along other direction, roller 5 is inwardly to lock circular step 401 with the mode of afore-mentioned symmetry, make input gear 1 drive fork controls dish 3 and output gear 4 to rotate, motor completes after the input of divertical motion angle of rotation to counterturn again, make input gear 1 can produce one with the minor rotation of former direction of rotation, now move to arc groove 101 directions at the tangent point of contact of roller 5 and transition camber line 103, in conjunction with the effect of spring sheet 601,602, roller 5 produces a radially outer movement, throw off the locking to circular step 401, make clutch get back to state of rest as shown in Figure 2, under static state, output gear 4 can not contact other parts around rotating shaft 2 independent rotation, thereby makes output terminal independently moving, can depart from the transmission system of motor.
Fig. 4 to Fig. 5 illustrates another kind of example of the present invention, comprises input gear 1, rotating shaft 2, fork controls dish 3, output gear 4, roller 5, damping device 7, and it does not have spring sheet 6 from different being only in last exemplary construction.
Working procedure and the previous examples of this example are similar: under state of rest, whole clutch is in position as shown in Figure 5, when driving input gear 1, electric machine rotation rotates along a direction, due to the surface friction drag of damping device 7, fork controls dish 3 can not be followed at once input gear 1 and be rotated, input gear 1 and fork controls dish 3 produce relative rotation, roller 5 detaches arc groove 101, a bit tangent with transition camber line 103 on roller 5 circumference, another point is tangent with groove 302 sidewalls, along with increasing in relative rotation, roller 5 is locking circular step 401 inwardly, now the surface friction drag of damping device 7 is not in the rotation that can limit fork controls dish 3, input gear 1 will drive fork controls dish 3 and output gear 4 rotating in same directions, and then complete the control of motor to output terminal, in like manner, in the time that motor drives input gear 1 to rotate along other direction, roller 5 is inwardly to lock circular step 401 with the mode of afore-mentioned symmetry, make input gear 1 drive fork controls dish 3 and output gear 4 to rotate, motor completes after the input of divertical motion angle of rotation to counterturn again, make input gear 1 can produce one with the minor rotation of former direction of rotation, now move to arc groove 101 directions at the tangent point of contact of roller 5 and transition camber line 103, the power radially inwardly acting on roller 5 is removed, roller 5 is thrown off the locking to circular step 401, makes clutch get back to state of rest as shown in Figure 2, under static state, output gear 4 can be around rotating shaft 2 independent rotation, the roller 5 that lacks spring sheet constraint is in free state, may follow output gear 4 to do the rotation around self turning axle, but can reverse locking input gear 1, be the transmission system that can depart from motor thereby make the independently moving of output terminal.
Clutch configuration involved in the present invention is simple, can stably realize input end and can drive output terminal at clockwise and anticlockwise both direction, and output terminal clockwise and anticlockwise both direction can not drive the function of input end, and control mode is simple, there is no extra manual or electronic control inputs.
Above example has only been set forth basic principle of the present invention and characteristic; the present invention is not limited by above-mentioned example; without departing from the spirit and scope of the present invention; the present invention also has various variations and change; the for example shape of transition camber line 102,103; the quantity of roller and corresponding holding space thereof, the shape of groove 302, these variations of the form of damping 7 and change all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
