The damp driving mechanism that holds shown in Figure 1 is to realize the object of the invention key structure.On the input shaft I-I that the good transmission case 2 of encapsulation stretches out previously, setting can about the driving of alternately trampling up and down with stampede body 1, on the output shaft II-II that transmission case 2 stretches out later, connect 3 and dowel bars 4 of a coupling (universal joint), on the other end of dowel bar 4 and wheel 8, a pair of umbrella gear (or ring gear) 6 and 7 is set, output shaft II-II, universal joint 3, dowel bar 4 and umbrella gear 6 and 7, all be arranged in the closed tube 5, transmission case 2 is connected by closed tube 5 with wheel axle 8.Its working principle is when alternately constantly stepping on the pedal 1-3 of stampede body 1 or 1-6 or 1-8 (seeing Fig. 5,6,7) up and down when left and right sides pin, under the effect of body weight, make the input shaft I-I left and right sides alternatively swinging constantly in the transmission case 2, and then output shaft II-II is rotated to clockwise direction all the time.Driving moment by output shaft II-II spreads out of by gimbal coupling 3, dowel bar 4 and a pair of umbrella gear (or ring gear) 6 and 7, makes wheel 9 to rotation counterclockwise, makes the manpower transportation to overtake.

Fig. 2 and Fig. 3 swing for reaching input shaft I-I, make output shaft II-II become two kinds of embodiments of holding damp driving mechanism of unidirectional rotation.An input shaft I-I and an output shaft II-II be arranged in parallel in the transmission case that holds damp driving mechanism 2 shown in Figure 2, on input shaft I-I, fix a sprocket wheel 2-1 and a gear 2-3 who has pawl structures who has pawl structures, the outer shroud of ratchet 2-6 on the sprocket wheel 2-1 can rotate in the direction of the clock, the outer shroud of ratchet 2-7 on the gear 2-3 can be by rotation counterclockwise, on output shaft II-II, correspondingly fix a sprocket wheel 2-2 and a gear 2-4, sprocket wheel 2-1 and sprocket wheel 2-2 be with chain 2-5 transmission, gear 2-3 and the gear 2-4 transmission that is meshing with each other.When input shaft I-I presses the clockwise direction rotation of thin arrow, sprocket wheel 2-1 makes output shaft II-II rotate to clockwise direction by chain 2-5 driving sprocket wheel 2-2, though gear 2-3 and gear 2-4 engagement this moment, but because the effect of the ratchet 2-7 on the gear 2-3, make the gear 2-3 not carry-over moment that dallies, when input shaft I-I counterclockwise rotates by thick arrow, gear 2-3 actuation gear 2-4, output shaft II-II is also rotated to clockwise direction, this moment is because the effect of the ratchet 2-6 on the sprocket wheel 2-1, make the sprocket wheel 2-1 not carry-over moment that dallies, input shaft I-I left and right sides two way alternate swing like this can make output shaft II-II all the time continuously to clockwise Fang Xuanchuan.

When if the direction that the ratchet 2-6 of the sprocket wheel 1 on the input shaft I-I and the ratchet 2-7 of gear 2-3 place is opposite with ratchet direction shown in Figure 2 separately, the two way alternate swing of the input shaft I-I left and right sides, can make output shaft II-II all the time continuously to rotation counterclockwise, but this is opposite with the direction that the driving manpower transportation travels, so impracticable.

In the four kind combinations different of the ratchet setting shown in Fig. 2 structure, have only two groups can make output shaft II-II all the time continuously to rotating clockwise and counterclockwise with placement direction, also the handlebar ratchet is arranged in four kinds of combinations on sprocket wheel 2-1 and the gear 2-4 two groups, also can realize making output shaft input shaft I-I all the time to clockwise or anticlockwise rotation, other compound mode in addition all can not realize the unidirectional rotation of bidirectional swinging or the output shaft II-II of input shaft I-I.

Fig. 2 and structure middle sprocket 2-1 shown in Figure 3 and sprocket wheel 2-2, available belt pulley or flute profile wheel or rope sheave replace, ratchet 2-6 and 2-7 also can adopt roller friction type or eccentric segment piece friction type ratchet, but its transmission principle are identical except that the common structure that adopts as shown in Figure 2.Fig. 3 is on the input shaft I-I, fix a gear 2-8 and a gear 2-10 who has pawl structures who has pawl structures, the placement direction of ratchet is opposite with Fig. 2, on output shaft II-II, correspondingly fix a gear 2-9 and a gear 2-11, gear 2-8 on the input shaft I-I and the gear 2-9 on the output shaft II-II transmission that is meshing with each other, gear 2-10 on the input shaft I-I and the gear 2-11 on the output shaft II-II, by an idle wheel 2-12 engagement driving, but its working principle and working principle shown in Figure 2 are identical.The claimant thinks that the structure of sprocket wheel, chain and gear shown in Figure 2 or flute profile wheel, flute profile band and Gear combination is comparatively reasonable.

According to the requirement of the device or the usability of machine, the different fit dimensions of design sprocket wheel 2-1,2-2 and gear 2-3,2-4 can obtain different velocity ratios.

Fig. 4 is for realizing the structural representation of wheel fallback function.The spline coupling of allocating in the output shaft II-II endoporus 14, when under the effect of pressure spring 13, being in mated condition with the splined hole of spline Hooks coupling universal coupling 15 1 ends, can the transmission of drive force square, when spline coupling 14 is in as shown in Figure 4 the state of pulling out, when breaking away from the splined hole of spline Hooks coupling universal coupling 15 1 ends, can not pass to the moment of rotation that wheel 9 retreats on the output shaft II-II, can make wheel 9, reach the purpose that the manpower transportation is retreated to the clockwise direction revolution.
