[embodiment]
Below in conjunction with accompanying drawing, the invention will be further described, and the structure of this device and principle are very clearly concerning the people of this specialty.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in Fig. 1 to 7, that a kind of pulley and flexible strand are wound around drive mechanism, wherein A, B, C, D, E are driven pulley, one end of flexible strand connects the first driving source, and flexible strand is wound around and is arranged on some driven pulleies, and the other end of flexible strand connects the second driving source, some driven pulley top-bottom layout, driven pulley is above arranged on the same axis, and driven pulley is below installed on another root axle, and unilateral bearing installed by driven pulley below.Flexible strand is as driving and linkage structure, be wrapped in driven pulley groove surfaces and connect the first driving source and second driving source at two ends, when the first driving source acting, second driving source of other one can be allowed to be returned to acting position by winding mechanism, realize interlock, coordinate unilateral bearing, when the reciprocal folding and unfolding in the two ends of flexible strand, driven pulley can be driven alternately to rotate and produce driving force by the latch functions of unilateral bearing, thus driving driven object body to rotate.
Its principle is: when flexible strand first drives source to move downward, and flexible strand will be driven downward, by canoe, the flexible strand of the second driving source is moved upward, thus the second driving source is moved upward.Two pulleys in view of downslide wheels are all assembled with unilateral bearing (in figure, the rotatable direction of unilateral bearing is downward-i.e. clockwise direction) and the sense of rotation of pulley B and D is contrary.When the first driving source moves downward, pulley B is for turning clockwise, and pulley D is for being rotated counterclockwise.According to unidirectional pulley characteristic, the unilateral bearing of pulley D can embrace coupling shaft, and therefore the rotation of pulley D can drive coupling shaft to be rotated counterclockwise, thus drives driving wheel counterclockwise to rotate.When the second driving source traction flexible strand moves downward, equally also moved upward by drive first driving source, the sense of rotation of pulley B is that the direction of pulley D is clockwise counterclockwise simultaneously, then drive coupling shaft is rotated counterclockwise by pulley B, thus drives driving wheel to rotate.
Back and forth moved up and down by flexible strand first driving source, the continuous of the second driving source two ends, driving wheel can being made ceaselessly along counterclockwise rotating, becoming continuous print power source.Driving wheel can use the kind of drive such as belt or chain to carry out transferring power to other objects.
Embodiment 1
Flexible strand transmission in the present invention can application example be pedal type bicycle or scooter, and as shown in accompanying drawing 8-10, in Fig. 8, dotted portion is above-mentioned pulley, flexible strand driving mechanism, and the direction of arrow is driving force direction.One of flexible strand is connected to side pedal (pedal installs pulley), is installed on pulley successively simultaneously, then is connected to other side pedal by one of flexible strand according to the layout be wound around.Driven pulley is altogether 5, top-bottom layout, above 3 be installed on the same axis, below 2 (installation unilateral bearings) be installed on the same axis.By left and right pin up and down reciprocatingly pedal, two pulleys below are constantly rotated along contrary direction.By single direction rotation and the latch functions of unilateral bearing, driven pulley can be made alternately to drive transmission shaft to rotate.Transmission shaft thus the sprocket wheel/belt pulley of drive installation on the same axis rotate consistently, the rotation of driving wheel acting can be delivered to driven object body by the transmission carrier such as belt or chain, by this structure, the action that pin is stepped on can be changed into motivational drive rear wheel, take little effort, acting utilization ratio is high.
