The specific embodiment
Be existing two-person ridden bicycle as shown in Figure 6 and Figure 7, its major programme is axis drive system 2 and back axis drive system 3 before being connected by crossbeam 1, preceding axis drive system 2 comprises front stall 19, preceding axis 11 and preceding axis sprocket wheel 12, and back axis drive system 3 comprises crossbeam 1, back seat 18, back axis 20, back axis sprocket wheel 21; Back axis sprocket wheel 21 wherein is the flywheel structure of bidentate wheel, axis sprocket wheel 12 and rear flywheel 22 before bidentate wheel connects by chain respectively, the ratchet structure of preceding axis sprocket wheel 12, back axis sprocket wheel 21 and rear flywheel 22 inside (be also referred to as flywheel, the mechanism of kowtowing) direction arranges identical.Two people can pass through pedal drive respective side axis sprocket wheel respectively when driving, and then the driving bicycle moves ahead.
As shown in Figure 1, the present invention improves existing two-person ridden bicycle, has set up force aid system 4 in preceding axis drive system 2, and force aid system wherein is the wheeled structure of hand-driven crank chain, and two power drive and the effect of body-building to reach.
Specific embodiment is:
As shown in Figures 2 and 3, a kind of double pair of power body-building bicycle, comprise the force aid system 4 on the axis drive system 2 before being installed in, wherein force aid system 4 comprises drive spindle 6, connecting rod 7, crank and chain-wheel 5 and driven ratchet 8, the one end strand of drive spindle 6 is contained on the crossbeam 1, can enough be the basic point swing with the end; Crank and chain-wheel 5 is installed on the front stall pipe 9, is positioned at a side of front stall pipe 9, and with axis sprocket wheel homonymy, be preferably by bearing and connect and front stall pipe 9; The one end strand of connecting rod 7 is contained on the drive spindle 6, and its other end is coupling on the crank 10 of crank and chain-wheel 5; On the axis 11, body was captiveed joint (as shown in Figure 3) with the outer sleeve body of preceding axis sprocket wheel 12 in it before driven ratchet 8 was sleeved on; Crank and chain-wheel 5 and driven ratchet 8 are connected by chain.
As shown in Figure 4 and Figure 5, preceding axis sprocket wheel 12 wherein and the ratchet structure direction of driven ratchet 8 arrange on the contrary, the identical setting of ratchet structure direction of preceding axis sprocket wheel 12 and back axis sprocket wheel 21.
When driving, the external reservoir person and after the person of taking advantage of be sitting in respectively on front stall 19 and the back seat 18, can be by preceding axis drive system 2, back axis drive system 3, force aid system 4 drives respectively or cooperate driving jointly, the moving ahead of realization bicycle.The external reservoir person controls garage's direction by the front truck handle, the interior body that drives preceding axis sprocket wheel 12 by step tread rotates the rotation of drive outer sleeve body, the outer sleeve body and the preceding axis sprocket wheel 12 that drive back axis sprocket wheel 21 by chain rotate in the same way, and then rotate moving ahead of realization bicycle in the same way by chain drive rear flywheel 22; The outer sleeve body rotation direction of axis sprocket wheel 12 is teeth directionals of body in it before this moment, and body does not rotate in can not driving, and back axis pedal is unaffected simultaneously; This moment driven ratchet 8 interior body subsequently the outer sleeve body of axis sprocket wheel 12 rotate synchronously, it is along its teeth directional that the interior body of driven ratchet 8 turns to, and can not drive its outer sleeve body and rotate, so force aid system 4 is unaffected.In like manner, when the 12 independent drivings of back axis sprocket wheel or force aid system 4 independent drivings, can not interfere other type of drive, and actual driving in the process, can the three operate simultaneously, improve the efficient that drives.
Above-mentioned force aid system 4 driving principle are: after the person's of taking advantage of swing drive spindle 6, driving crank 10 by connecting rod 7 rotates, and then the rotation of realization crank and chain-wheel 5, rotate by the outer sleeve body that chain drives driven ratchet 8 this moment, drives body rotation in the same way thereupon in it; Before this moment in axis sprocket wheel 12 and the driven ratchet 8 bodies is connected thereupon and rotates synchronously, and then drive outer sleeve body and rear flywheel 22 rotations of back axis sprocket wheel 21, the moving ahead of realization bicycle.By aforesaid analysis as can be known, the interior body of axis sprocket wheel 12 and back axis sprocket wheel 21 and stretcher can not rotate mutually noninterfere thereupon together before this moment.
In addition, in the specific implementation, can also further design array structure down: the other end at connecting rod 7 arranges handle 13, is convenient to help; Back seat 18 at two-person ridden bicycle is installed backrests 17, after the person of taking advantage of when backward spurring drive spindle 6, as acting point, when promoting drive spindle 6 forward, back props up backrest 17 as acting point to pedal, the antagonistic force when pushing away drive spindle 6 with counteracting on pedal; Cross dead point boosting slide board or magnet piece 14 at the first dead center of crank and chain-wheel 5 and connecting rod 7 drivings, the arc that adjustable protrusion is installed on the lower dead point next door respectively; The elasticity that tunable front end is equipped with bearing or magnet piece is crossed 15 of dead point power-assisted plates and is connected on the crank 10, spring 16 acts on the elasticity that tunable front end is equipped with bearing or magnet piece and crosses between dead point power-assisted plate 15 and the crank 10, when crank and chain-wheel 5 and connecting rod 7 drives at first dead center or lower dead point place, relatively crank 10 the rubber-like front end elasticity that is equipped with bearing or magnet piece cross the front end sliding pressure of dead point power-assisted plate 15 above the arc of adjustable protrusion is crossed dead point boosting slide board or magnet piece 14, this moment, spring 16 or the same sex two magnet pieces repelled each other the elastic force counteraction that produces on crank 10, make crank 10 cross dead center position at place, dead point nature bullet, and then under the effect of connecting rod 7, be garden Zhou Yundong, and then drive crank and chain-wheel 5 driving cycle racings.
The present invention is when driving, the external reservoir person controls direction and foot-operated propulsive effort is provided, after the person of taking advantage of carry out hand-drive or pin and drive, both can two people drive simultaneously, also can a people drive, especially only by after the person of taking advantage of propulsive effort is provided, and the external reservoir person only controls direction, improved the enjoyment that drives greatly, especially the significantly action of upper limbs can be played effectively body-building effect.In addition, the connecting rod in the force aid system of the present invention, the angle of itself and drive spindle is near 90 degree, and effective travel is big, the efficient height of driving.In addition, compared to common front truck driving two force bikes, the present invention be by after the person of taking advantage of realize hand-drive, and front truck is being exclusively used in the control direction, safety performance is higher.
It should be noted that at last, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although with reference to preferred embodiment the present invention is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not breaking away from the spirit and scope of technical solution of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
