Description

A kind of exercising bicycle with secondary transmission

Technical field

The present invention relates to a kind of multifunctional traffic means, relate in particular to a kind of exercising bicycle with secondary transmission.

Background technology

General bicycle mainly comprises handlebar and vehicle body, the car front-wheel is installed on the handlebar, chain drum is installed at the vehicle body middle part, tail of body installation car trailing wheel is coaxially installed with flywheel on the trailing wheel, sprocket wheel and flywheel are by the chain transferring power, the right overhead two ends of sprocket wheel are installed with crank, crank is Central Symmetry on the chain drum plane, and the horizontal fixed rotating shaft of the movable end of crank rotates in the rotating shaft to install and rides.During the bicycle running, pin is trampled the pedal drive sprocket rotation, the chain-driving flywheel rotation on the sprocket wheel, and then drive the trailing wheel rotation.

As the vehicle, the advantage such as that bicycle has is light, environmental protection is if can be transformed bicycle, make its not only easy to use, environmental protection and energy saving, and can also take exercises, and have fairly obvious body-building effect, this will make newly usefulness of bicycle past heritage, open the brand-new purposes of bicycle.

Summary of the invention

The invention provides a kind of exercising bicycle with secondary transmission that has both simultaneously walking-replacing tool and health and fitness facilities effect, and its body-building effect is very remarkable.In order to realize the foregoing invention purpose, the present invention has adopted following technological means:

A kind of exercising bicycle with secondary transmission comprises handlebar and vehicle body; On the described handlebar front-wheel is installed; The afterbody of described vehicle body is installed trailing wheel; Described vehicle body middle part is equipped with driving gear disc and driven fluted disc; Rotate respectively on the both sides card of described driving gear disc two curved bars, two center of turns off-centre and Central Symmetry on driving gear disc are set; The other end of described curved bar and the middle part of pedal are hinged; The end of described pedal is hinged on the vehicle body; All be coaxially installed with flywheel on described driven fluted disc and the trailing wheel, described driving gear disc is in transmission connection by the flywheel of one-level chain and driven fluted disc; Described driven fluted disc is in transmission connection by the flywheel of secondary chain and trailing wheel; The hinge-point of vehicle body and two pedals is positioned at the place ahead of driving gear disc, the distance at hinge-point and driving gear disc center is d=30cm, the radius of rotation of the center of turn on the described driving gear disc is r=4cm, the distance of two hinge-points on the curved bar is m=15cm, and the distance of two hinge-points on the pedal is R=20cm.

The symmetrical both sides that are hinged on vehicle body of described pedal;

Be equipped with on the described vehicle body and tighten up gear; Described tighten up gear from the outside jack-up one-level chain from bottom to top.

Beneficial effect of the present invention is: adopt pedal to swing up and down and drive the driving of driving gear disc rotation realization bicycle, the people stands on that pushes pedals swings up and down it on the pedal, drive on the one hand bicycle and move the performance effect of riding instead of walk, simulation is run to move and is realized taking exercises on the other hand; Adopt the mode of secondary transmission, strengthen the converter speed ratio between driving gear disc and the trailing wheel, more exert all one's effort so that drive bicycle, promoted the effect of body-building; Pedal is symmetrical set, and makes it more meet organization of human body, uses more comfortable.

Description of drawings

Fig. 1 is the structural representation of a kind of exercising bicycle with secondary transmission of the present invention.

The specific embodiment

Below in conjunction with accompanying drawing, the preferred implementation of a kind of exercising bicycle with secondary transmission of the present invention is made detailed description:

As shown in Figure 1, the enhancing body resistance bicycle mainly comprises handlebar 1 and vehicle body 2, and handlebar 1 rotates the head that is arranged on vehicle body 2; Front-wheel 11 is installed on the handlebar 1; The medium position of vehicle body 2 rotates driving gear disc 3 and driven fluted disc 5 is set, driving gear disc 3 is positioned at the place ahead of driven fluted disc 5, the afterbody of vehicle body 2 is installed trailing wheel 6, all be coaxially installed with flywheel on driven fluted disc 5 and the trailing wheel 6, driving gear disc 3 is in transmission connection by the flywheel of one-level chain 4 and driven fluted disc 5, driven fluted disc 5 is in transmission connection by the flywheel of secondary chain 7 and trailing wheel 6, the converter speed ratio of the flywheel of driving gear disc 3 and driven fluted disc 5 is 2:1, and the converter speed ratio of the flywheel of driven fluted disc 5 and trailing wheel 6 is 2:1.

Be fixedly installed respectively two eccentric shafts on the both sides card of driving gear disc 3, two eccentric shafts are centrosymmetric in the card of driving gear disc 3, one end of eccentric shaft and curved bar 9 is hinged, the middle part of the other end of curved bar 9 and pedal 10 is hinged, pedal 10 is the shape of 60 ° of left end perks, the hinge-point of curved bar 9 and pedal 10 is positioned at the bending point place at pedal 10 middle parts, and the end of pedal 10 is hinged on the vehicle body 2, two pedal 10 symmetrical being hinged on the vehicle body 2.

The hinge-point of vehicle body 2 and two pedals 10 is positioned at the place ahead of driving gear disc 3, the distance at hinge-point and driving gear disc 3 centers is d=30cm, the radius of rotation of eccentric shaft is r=4cm, the distance of two hinge-points on the curved bar 9 is m=15cm, the distance of two hinge-points on the pedal 10 is R=20cm, such design guaranteed along with alternately the swinging up and down of pedal 10, and curved bar 9 can drive the left-hand revolution that driving gear disc 3 continues, thereby realizes continuing transmission.

Be fixedly installed one between the middle part driving gear disc 3 of vehicle body 2 and the driven fluted disc 5 and tighten up gear 8, tighten up gear 8 and withstand from bottom to top one-level chain 4 from the outside of one-level chain 4, thereby one-level chain 4 is tightened up, one-level chain 4 and the chain transmission number of teeth of the flywheel of driving gear disc 3 and driven fluted disc 5 are increased, thereby make driving gear disc 3 more stable with the transmission of one-level chain 4.

In the time of the work of enhancing body resistance bicycle, trample the pedal 10 in left side downwards, the curved bar 9 that pedal 10 drives the left side moves down, curved bar 9 drives driving gear disc 3 and rotates counterclockwise, along with left pedal 10 moves down, the eccentric shaft on right side rotates up, and drives the curved bar 9 on right side, and then the pedal 10 on pulling right side moves up; When the pedal 10 in left side arrives lower limit, the curved bar 9 on right side has turned over flex point, the moment of the curved bar 9 pulling driving gear discs 3 on right side becomes anticlockwise moment at this moment, trample again the pedal 10 on right side downwards, and then the curved bar 9 that drives the right side moves down, and curved bar 9 pulling driving gear discs 3 rotate counterclockwise.Along with alternately trampling left and right sides pedal 10 it is back and forth swung up and down, driving gear disc 3 is rotated by continual driving, thereby realizes constantly moving ahead of bicycle, and the 10 simulation running actions of people's pushes pedals, has realized simultaneously the purpose of taking exercises.Adopt the mode of secondary transmission to drive trailing wheel, total converter speed ratio of driving gear disc 3 and trailing wheel 6 is increased to 4:1 by the 2:1 of single-stage driving, need to use larger strength so that bicycle is trampled when moving ahead, and has promoted the effect of body-building.
