The specific embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
As shown in Figure 1 and Figure 2, a kind of pedal type step bicycle, by the pendulum-type scooter of human body gravity or legpower realization transmission of power and acceleration, it comprises forward wheel components, rear wheel part and frame part.
Forward wheel components mainly is leading and the control direction of traffic, the front-wheel 10 that specifically comprises leading direction of traffic, the handlebar 3 of control direction of traffic, control vehicle brake or the brake handlebar 2 that slows down, the fixing front-wheel breeches pipe 4 of front-wheel 10 and articulator handle riser 1, hinged front-wheel breeches pipe 4 and connect the stem 1 of handlebar 3.
Frame part is mainly by forming with left and right pedal 71,72 bonded assembly connecting rod crank mechanisms and with this connecting rod crank mechanism bonded assembly sprocket wheel speed-changing mechanism as driver train.Wherein, left and right pedal 71,72 transmits the power of the people's both feet of riding, and connecting rod crank mechanism swings up and down two pedals and converts crank shaft 15 unidirectional rotations forward to, and the sprocket wheel speed-changing mechanism realizes that trailing wheel quickens.
Particularly, second drive sprocket 11 and second driven sprocket 17 that cooperates with these second drive sprocket, 11 chains of first driven sprocket 12 that this sprocket wheel speed-changing mechanism comprises that one first drive sprocket 14, one cooperate with these first drive sprocket, 14 chains, one and these first driven sprocket, 12 coaxial settings, this first driven sprocket 12 is the doubly-linked sprocket wheel with this second drive sprocket 11, and second driven sprocket 17 is unidirectional flywheel; These two groups of connecting rod crank mechanisms comprise with this left and right connecting rod 51,52 of left and right pedal 71,72 bonded assemblys and with the left and right crank 61,62 of these left and right connecting rod 51,52 bonded assemblys, and this left and right crank shaft 15 is provided with this first drive sprocket 14.
Rear wheel part specifically comprises: with the driving trailing wheel 8 that 17 coaxial settings of second driven sprocket and powered vehicle move ahead, adopt second driven sprocket 17 in the sprocket wheel speed-changing mechanism of unidirectional flywheel form like this, the unidirectional delivery moment of torsion drives trailing wheel 8 and quickens to rotate; Drive trailing wheel 8 inboards and also be provided with brake assemblies 16 pairs of vehicles implementations brake or deceleration; Drive trailing wheel 8 bilateral symmetry and be provided with two differential trailing wheels 91,92, it realizes the back wheel speed difference automatically regulating of vehicle when turning, and supporting bracket guarantees vehicle static state, balance and stability dynamically the time.
When the people that rides uses this pedal type step bicycle, its bipod stands on left and right sides pedal 71 respectively, on 72, do the action of marking time, utilize human body gravity alternately with pedal 71,72 step on, when a side pedal step on affect this side connecting rod 51 or 52 and crank 61 or 62 drive crank shafts 15 unidirectional rotate forward (shown in arrows among Fig. 2), thereby drive first drive sprocket 14 and first driven sprocket 12 (doubly-linked sprocket wheel) on the crank shaft 15, finished with second driven sprocket 17 (unidirectional flywheel) and chain 13 interlocks by second drive sprocket 11 (doubly-linked sprocket wheel) acceleration that drives trailing wheel 8 is rotated, powered vehicle moves ahead.Meanwhile, because crank 61,62 is at crank shaft 15 two ends, its crank direction is respectively on crank shaft 15 circumference 180 degree orientation, so in addition side crank 61 or 62 and connecting rod 51 or 52 promote other side pedals and go upward to top dead point, step on down at once, finish above transmission, acceleration equally, promote the up overall process of other side pedal simultaneously, powered vehicle constantly moves ahead.
Above-mentioned sprocket wheel speed-changing mechanism also can adopt gear change or other speed-changing mechanisms to substitute, and allly makes similar variation or modification according to the principle of the invention or version, all falls into protection domain of the present utility model.
As shown in Figure 3-Figure 5, for when vehicle uses, can be with being about to handlebar 3 and stem 1 expansion, and when vehicle must be deposited or carry, with handlebar 3 and stem 1 being folded on the vehicle frame pedal, be provided with the interior sheet 11 of knuckle joint of a convex shape in this stem 1, this front-wheel breeches pipe 4 is provided with the knuckle joint outer plate 41 of a concave shape, stem 1 inserts in the front-wheel breeches pipe 4, and in this knuckle joint sheet 11 and this knuckle joint outer plate 41 by bolted splice.
