The present invention becomes the mode of swing by the rotation with foot-driven lever, makes them no longer close on " stagnant wake " position.So just improved mechanical efficiency, calculated demonstration, (with respect to horizontality bi-directional symmetrical 60 degree) cyclist's acting loss has reduced 30% when foot-driven lever swings to 120 degree angles.
The present invention equally also can be used as exercising machine and uses, and is used for the patient's of knee joint or pin operation on joint rehabilitation, perhaps is used to have the people of pin joint problem to carry out recovery training.
Description of drawings
The installation site of Fig. 1 the present invention on bicycle rack.
Changer longitudinal sectional view among Fig. 2 the present invention, promptly the 1-1 among Fig. 1 is to cutaway view.
The specific embodiment
As shown in Figure 1, the present invention includes the changer 22 that is installed on the bicycle rack 21, this changer transmission shaft is stretched out by two ends, by axle sleeve left pedal rod 9 and right pedal bar 10 is set respectively, the left and right foot-driven lever certain angle that staggers as required, present embodiment are the 120 degree angles of staggering.The external part of changer 1 transmission shaft also is equipped with driving gear 13, and driving gear 13 and driven gear 24 engagements that are installed in drive sprocket axle 23 axle heads drive the chain gear of bicycle driving wheel.(not expression on Fig. 1).
Changer mainly comprises housing 1, transmission shaft 2, left axle sleeve 3, right axle sleeve 4, two one-way drive clutch 8, two drive bevel gear 7, a driven wheel of differential 14 as shown in Figure 2.Wherein: left axle sleeve 3 and right axle sleeve 4 are bearing in the both sides of transmission shaft 2 respectively by the clutch shaft bearing 6 and second bearing 6 ', fixing left foot treadle 9 on the left axle sleeve 3, the treadle 10 of anchoring the right foot on the right axle sleeve 4, and left and right foot-driven lever 9,10 certain angle that staggers; Left and right axle sleeve 3,4 outer rims are held the 5 and the 4th bearing 5 ' by third axle respectively and are bearing in the housing 1; Left and right axle sleeve 3,4 relative sides are installed one-way drive clutch 8 respectively, and the driving link of each one-way drive clutch 8 connects a drive bevel gear 7 respectively, these two drive bevel gear, 7 common and driven wheel of differential 14 engagements.Fig. 3 is the cutaway view of one-way drive clutch in the changer, and its principle of work is similar to the flywheel in the ordinary bicycle.
Device is worked in such a way:
Pedal rod is made periodic wobble under the effect of cyclist's strength of one's legs.Pedal rod is 120 ° swing as amplitude in this example, from horizon, and each 60 ° of (see figure 1) of the every side in both sides.Suppose that cyclist's strength of one's legs affacts on the left pedal rod 9 in the given period, in the effect bottom left pedal rod 9 anticlockwise directions rotation of power, promptly left pedal rod 9 moves downward.Left axle sleeve 3 and the driving link of one-way drive clutch therewith 8 and the drive bevel gear 7 in left side in addition that rotate on same direction with left pedal rod 9 this moment.Then, driven wheel of differential 14 is passed to this action the drive bevel gear 7 on right side, but because gear mesh break-in, the drive bevel gear 7 on right side is rotated in a clockwise direction, therefore, the driving link, right axle sleeve 4 and the right pedal bar 10 that drive right one-way drive clutch 8 move clockwise and dally, in other words, and right pedal bar 10 upward movements.Get back to specified angle when right pedal bar 10, can be supported on (not expression on Fig. 1 and Fig. 2) on the killer, and finish the forced stroke of left pedal rod 9 at this point.The right pedal bar 10 of this moment occupies uppermost position, and cyclist's pin begins to trample right pedal bar 10 downwards, begins its forced stroke.This motion is with the above is similar, makes left pedal rod 9 counter motions, that is left pedal rod 9 makes idle running and upward movements, and like this, the pedal rod motion cycle repeats.
