In background technology, mention the tread bicycle key of success and be to solve frequent noise and immalleable this problem of frequent vibrations of cyclist that produces by the idle running bump, do not solve to can be compared to and on the sandy beach, build high building, must end in failure.The accurate individual event propelling unit of soft landing has been realized shockproof, its anti-noise, successful solution this technical barrier.The accurate individual event propelling unit of soft landing is made of left accurate individual event propelling unit 23 that is installed in two ends, axis 27 left and right sides and right accurate individual event propelling unit 24.About the angle of rake structure of accurate individual event identical, measure-alike, symmetrical.So emphasis is understood the angle of rake structure of left accurate individual event and just can be understood all.The angle of rake core of the accurate individual event in a left side is interior annulus and outer shroud, interior annulus is called basic annulus, outer shroud is called individual event and promotes ring, the basis annulus is two-sided, the outside is called basic annulus A face 37, the inboard is called basic annulus B face 39, and A face, B face respectively have N steel body sliding tray 45, and one piece of slip steel body 60 and one piece of centnifugal force spring 59 (Fig. 9) are respectively arranged in each steel body sliding tray.Rectangular distribution N+1 or N-1 individual event promote groove 48 on the interior circle of individual event promotion ring (Fig. 8), a side of groove is that the inclined-plane is called individual event promotion groove inclined-plane 50, another side of groove is called individual event and advances groove load-carrying face 49, the bottom surface that individual event promotes groove 48 is a soft landing elastic body 51, elastic body 51 has two important elastic surfaces, one is tangential direction elastic surface 52, and another is a centrifugal direction elastic surface 53.Soft landing elastic body 51 is easily changeable, and old soft landing elastic body 51 is extracted out from the side, new soft landing elastic body is pushed from the side get final product.The cylindrical that individual event promotes ring is a wire casing 35, the center of basis annulus is axis hole 47 and locating platform 46, they respectively with axis 27 and axis positioning groove 31 precision-fit (also available certainly key pin mode makes axis 27 and axis hole 47 precision-fit), tighten fixingly then with check screw 34, this structure is easy to loading and unloading.In the angle of rake wire casing 35 of the accurate individual event in a left side, fix two the end of a thread with two the end of a thread retainingf keys 26, the one, the upper end of left traction steel wire 21, the 2nd, the left end of commutation reversing draught line 13.In the wire casing 35 of the accurate individual event propelling unit 24 in the right side, fix two the end of a thread equally with two the end of a thread retainingf keys 26, the one, the upper end of right traction steel wire 22, the 2nd, the right-hand member of the commutation reversing draught line 13 after walking around angle pulley 12.It is fixing together with the top of the end of a thread and damping flexure strip 20 with the end of a thread retainingf key 25 afterwards that the damping flexure strip 20 of straight treadle 15 lower ends, a left side is walked around in the lower end of left side traction steel wire 21.It is fixing together with the end of a thread and damping flexure strip top with the end of a thread retainingf key 25 afterwards that the damping flexure strip 20 of right straight treadle 66 lower ends is walked around in the lower end of right traction steel wire 22.Want to realize shockproof, its anti-noise, must dwindle the idle running distance as far as possible, dally apart from changing between the 0-0.6 millimeter according to the design of Fig. 5, aviation value is 0.3 millimeter.Can obtain good like this effect, from structural two features: 1, N:N+1 or N-1 structure, at angle of rake A face of accurate individual event or B face, if the quantity of steel body sliding tray 45 is N, the quantity of individual event promotion groove 48 is N+1 so, if it is N that individual event promotes the quantity of groove 48, the quantity of steel body sliding tray 45 is N+1 so, the former is more accurate than the latter, can prove that N:N+1 is simple and reasonable for structure, idle running distance (arc length) minimum, the little idle running distance of N is big, little but the big weight of volume of the big idle running of N distance increases, and accompanying drawing is drawn by N=12.2, the angle of rake bilateral structure of the accurate individual event of soft landing, the quantity of A face B face steel body sliding tray is identical, structure is identical, but A face B face differs an angle, this angle on the basis on round week cooresponding arc length be 1/2nd of the maximum idle running of single face distance.For example Fig. 5 is accurate individual event propelling unit A face, and the maximum idle running distance of A face is 1.2 millimeters.The A face B face angle that interlaces, this angle on the basis on round week cooresponding arc length be 1.2 millimeters 1/2nd be 0.6 millimeter.When the idle running of A face was 1.2 millimeters apart from maximum, the idle running of B face distance was 0.6 millimeter, and when the idle running of B face was 1.2 millimeters apart from maximum, the idle running of A face distance was 0.6 millimeter.A face B face is used simultaneously in other words, and the idle running distance changes between the 0-0.6 millimeter, and average idle running distance is 0.3 millimeter.
Pedal from nadir the distance to vertex total travel.Owing to the increase of physical fatigue sense along with the knee joint bending angle increases.The structure of pedal rebound bicycle helps compressing total travel, and the knee joint bending angle is little, so the muscle power performance is in laborsaving.We are divided into two sections with total travel from the centre, epimere is called up stroke, and hypomere is called down stroke.Obviously up stroke is in time laborsaving district down stroke and is in the most laborsaving district.Pedal when left foot and to enter the physical F soldier that the most laborsaving district the time acts on the pedal and divide four the tunnel, first via F1 is converted into the down stroke propelling thrust that advances, the second road F2 is to right energy stroage spring 18 energy storage, and Third Road F3 traction right crus of diaphragm makes progress, and the four road F4 draws right accurate individual event propelling unit outer shroud reversing.Right pedal 65 rises to vertex when left foot is pedaled 64 arrival nadirs, 18 bounce-backs of right this moment energy stroage spring release energy be converted into up stroke advance propelling thrust (right crus of diaphragm moves downward only needs very little power just can draw the left foot upward movement, draw left individual event promote to encircle reverse).The physical F soldier who acts on the right pedal when right pedal 65 enters the most laborsaving district divides four the tunnel.First via F1 is converted into the down stroke propelling thrust that advances, the second road F2 is to left energy stroage spring energy storage, Third Road F3 traction left foot upwards, the four road F4 draws left accurate individual event propelling unit outer shroud reversing, left foot is pedaled 64 and is reached vertex when right pedal 65 arrives nadir, left side energy stroage spring 18 begins bounce-back and releases energy and be converted into the up stroke propelling thrust that advances, (left foot moves downward only needs very little power just can draw the right crus of diaphragm upward movement, draw right individual event and promote the ring reversing), pedaling 64 when left foot enters the physical F soldier that the most laborsaving district the time acts on the pedal 64 and divides four road F1+F2+F3+F4, so circulation, the bounce-back structure concentrates on the most laborsaving district with the muscle power performance, so pedal rebound bicycle speed is fast, laborsaving, can be lasting.Among Fig. 3, Fig. 4, Figure 13, Figure 14, Figure 12 when right pedal 65 arrives nadirs, left foot is pedaled 64 and is risen to vertex, left side energy stroage spring begins bounce-back, and the damping flexure strip 20 of straight treadle 15 lower ends, a left side is converted into cushion effect with rebounce power and promotes ring by the left individual event of left traction steel wire 21 tractions and changed into by reversing and just change the preparation soft landing.Though the cushion effect time length only is in a flash, just this in a flash within idle running distance between tangential direction elastic surface 52 and the slip steel body soft landing face 61 shorten to 0 distance by 0-0.6 millimeter (according to the design of Fig. 5), so soft landing begins (Figure 13).Individual event promotes groove load-carrying face 49 and slip steel body load-carrying face 62 with the distance of same speed shortening between them in elastic body tangential direction elastic surface 52 compressed processes, achieves a butt joint at last.(Figure 14) finished in soft landing this moment.The pressure that elastic body tangential direction elastic surface was subjected to after soft landing finished no longer increases, so because the pressure that soft landing elastic body 51 is subjected to is limited long service life.Elastic body centrifugal direction elastic surface 53 is converted into soft landing with slip steel body 60 centrifugal direction impulsive forces, along with individual event promotes the ring reversing, individual event promotes groove inclined-plane 50 forces slip steel body 60 to be return in the steel body sliding tray 45 with the centripetal force that slip steel body curved surface 63 mutual actions produce.Because slip steel body load-carrying face 62 is positioned at bottom land, thus after the butt joint skidding can not take place, for the normal operation of pedal rebound push structure provides support.
