Description

A kind of secondary transmission body-building bicycle

Technical field

The utility model relates to a kind of multifunctional traffic means, relates in particular to a kind of secondary transmission body-building bicycle.

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 is installed back wheels of vehicle, is coaxially installed with flywheel on the trailing wheel, and sprocket wheel and flywheel are by the chain transferring power, the right overhead two ends of sprocket wheel are installed with crank, crank is the center symmetry on the chain drum plane, and the movable end horizontal fixed rotating shaft of crank is rotated in the rotating shaft to install and ridden.During the bicycle running, pin is trampled to ride and is driven sprocket rotation, and the chain on the sprocket wheel drives the flywheel rotation, and then drives the trailing wheel rotation.

As the vehicle, 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 bicycle past heritage usefulness newly, open the brand-new purposes of bicycle.

The utility model content

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

A kind of secondary transmission body-building bicycle 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 initiatively fluted disc and driven fluted disc; Rotate respectively on the both sides card of described active fluted disc two curved bars, two center of turns off-centre and center symmetry on the active fluted 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 active fluted 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 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.

The beneficial effects of the utility model are: adopt pedal to swing up and down and drive the driving of driving tooth disc spins realization bicycle, the people stands on that pushes pedals swings up and down it on the pedal, drive bicycle on the one hand 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 active fluted disc and the trailing wheel, make that driving bicycle more exerts all one's effort, and has 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 secondary transmission of the utility model body-building bicycle.

The specific embodiment

Below in conjunction with accompanying drawing, the preferred implementation of a kind of secondary transmission of the utility model body-building bicycle 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 initiatively fluted disc 3 and driven fluted disc 5 is set, initiatively fluted 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, initiatively fluted 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, initiatively the converter speed ratio of the flywheel of fluted 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.

Initiatively fixedly install two eccentric shafts respectively on the both sides card of fluted disc 3, two eccentric shafts are centrosymmetric on the card of active fluted 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 initiatively the place ahead of fluted disc 3, hinge-point is d=30cm with the distance at active fluted disc 3 centers, 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 fluted disc 3 initiatively continues, thereby realizes continuing transmission.

Fixedly install one between the middle part active fluted disc 3 of vehicle body 2 and the driven fluted disc 5 and tighten up gear 8, tighten up gear 8 and withstand one-level chain 4 from bottom to top from the outside of one-level chain 4, thereby one-level chain 4 is tightened up, also make one-level chain 4 and the initiatively chain-driving number of teeth increase of the flywheel of fluted disc 3 and driven fluted disc 5, initiatively fluted disc 3 is more stable with the transmission of one-level chain 4 thereby make.

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 initiatively, and fluted disc 3 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, curved bar 9 pullings on the right side at this moment initiatively moment of fluted discs 3 become anticlockwise moment, trample the pedal 10 on right side downwards, and then the curved bar 9 that drives the right side moves down, and curved bar 9 pullings initiatively fluted discs 3 rotate counterclockwise.Along with alternately trampling left and right sides pedal 10 it is back and forth swung up and down, initiatively fluted disc 3 is by continual driven in rotation, thereby realizes constantly moving ahead of bicycle, and people's pushes pedals 10 simulations action of running, and realized the purpose of taking exercises simultaneously.Adopt the mode of secondary transmission to drive trailing wheel, initiatively total converter speed ratio of fluted disc 3 and trailing wheel 6 is increased to 4:1 by the 2:1 of single-stage driving, makes bicycle trample when moving ahead and need use bigger strength, has promoted the effect of body-building.
