Abstract

The invention relates to a multifunctional bicycle, in particular to a reverse-driving two-stage transmission body building bicycle. The reverse-driving two-stage transmission body building bicycle comprises a nose and a body, wherein a front wheel is installed on the nose; a secondary flywheel and a rear wheel are coaxially installed at the tail of the body; a primary chain wheel and a secondary chain wheel are installed in sequence in the middle part of the body; a primary flywheel is coaxially arranged on the secondary chain wheel; a reverse flywheel is arranged in the backward position of the primary flywheel on the body; two pedals are hinged at the front part of the body; a crankshaft guide rail is arranged on each pedal; two centrosymmetrical cranks are fixedly connected on the rotating shaft of the primary chain wheel; a crankshaft is horizontally arranged on the free end of each crank; the crankshafts are limited in the crankshaft guide rails; the primary chain wheel and the reverse flywheel are in equidirectional transmission through a reverse chain; the primary flywheel and the periphery of the reverse chain are in matched transmission; and the secondary chain wheel and the secondary flywheel are in equidirectional transmission through a forward chain. The effect of body building is achieved when the pedals are trampled to drive the bicycle, and because two-stage transmission is adopted, the body building effect is improved.

Description

A kind of anti-secondary transmission body-building bicycle of driving

Technical field

The present invention relates to a kind of multifunction bicycle, relate in particular to a kind of anti-secondary transmission body-building bicycle of driving.

Background technology

General bicycle mainly comprises handlebar and vehicle body, and the car front-wheel is installed on the handlebar, and 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 through 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 if can bicycle be transformed, makes its not only easy to use, environmental protection and energy saving, and can also take exercises, and this will make bicycle past heritage usefulness newly, open the brand-new purposes of bicycle.

Summary of the invention

The invention provides a kind of anti-secondary transmission body-building bicycle of driving that integrates ride instead of walk function and body-building function.In order to realize the foregoing invention purpose, the present invention has adopted following technological means:

A kind of anti-secondary transmission body-building bicycle of driving comprises headstock and vehicle body; On the said headstock front-wheel is installed; Said tail of body is with axle mounting secondary flywheel and trailing wheel; Said vehicle body is installed one-level sprocket wheel and secondary sprocket wheel before and after the middle part successively; The coaxial one-level flywheel that is provided with on the said secondary sprocket wheel; Said vehicle body upper class flywheel position backward is provided with counter flywheel; Anterior hinged two pedals of said vehicle body; Said pedal is provided with the bent axle guide rail; Two centrosymmetric cranks of captive joint in the rotating shaft of said one-level sprocket wheel; The movable end of said crank is horizontally disposed with bent axle; Said bent axle is limited in the bent axle guide rail; Pass through the equidirectional transmission of counter-rotating chain between said one-level sprocket wheel and the counter flywheel; Said one-level flywheel cooperates transmission with the periphery of counter-rotating chain; Between said secondary sprocket wheel and the secondary flywheel through just changeing chain transmission in the same way.

Said bent axle guide rail is the linear pattern guide rail.

Beneficial effect of the present invention is: adopt pedal to swing up and down the drive sprocket contrarotation and realize that bicycle drives; The people stands on that pushes pedals swings up and down it on the pedal, drives bicycle on the one hand and moves riding instead of walk effect of performance, and body-building function is brought into play in the simulation action of running on the other hand; Adopt the mode of secondary transmission; Strengthen the converter speed ratio between one-level sprocket wheel and the trailing wheel, make that driving bicycle more exerts all one's effort, and has promoted the effect of body-building.

Description of drawings

Fig. 1 is a kind of anti-structural representation that drives secondary transmission body-building bicycle of the present invention;

Fig. 2 is the partial enlarged drawing of A part among Fig. 1.

The specific embodiment

Below in conjunction with accompanying drawing, a kind of anti-preferred implementation of driving secondary transmission body-building bicycle of the present invention is made detailed description:

As depicted in figs. 1 and 2, this anti-secondary transmission body-building bicycle of driving mainly comprises headstock 1 and vehicle body 2, and headstock 1 is rotatably installed in the head of vehicle body 2.Front-wheel 10 is installed on the headstock 1, and the afterbody of vehicle body 2 is installed trailing wheel 8, trailing wheel 8 and the 9 coaxial settings of secondary flywheel.

Rotate successively before and after the middle part of vehicle body 2 one-level sprocket wheel 3 and secondary sprocket wheel 5 are set, the coaxial one-level flywheel 6 that is equipped with on the secondary sprocket wheel 5, one-level flywheel 6 position backward also is provided with a counter flywheel 7.

Vehicle body 2 upper class sprocket wheel 3 positions forward; About a hinged pedal 4 respectively, pedal 4 extends to from hinge-point near the trailing wheel 8 always, the middle front part of pedal 4 belows; The steel disc of a U-shaped is installed, thereby below pedal 4, limits one section linear bent axle guide rail 41.

Be fixedly connected with the rotating shaft center symmetry of 11, two cranks 11 of two cranks with respect to one-level sprocket wheel 3 about in the rotating shaft of one-level sprocket wheel 3, specifically, two cranks 11 are in a straight line.The movable end of crank 11 is provided with the bent axle 12 of level, and bent axle 12 is limited in the bent axle guide rail 41.

One-level sprocket wheel 3 passes through the 13 equidirectional transmissions of counter-rotating chain with counter flywheel 7, and one-level flywheel 6 withstands from the periphery of counter-rotating chain 13 and tightens counter-rotating chain 13.Secondary sprocket wheel 5 is in transmission connection through just changeing chain 14 with secondary flywheel 9 in the same way.

This is counter to drive secondary transmission body-building bicycle when initiatively doing; Replace pushes pedals 4, under 41 restrictions of bent axle guide rail, bent axle 12 can drive 3 opposite spins of one-level sprocket wheels with crank 11; And then drive counter-rotating chain 13 contrarotations; Under the driving of counter-rotating chain 13, one-level flywheel 6 forwards drive secondary sprocket wheel 5 forward rotation, and then driving trailing wheel 8 rotates forward.Adopt pedal 4 to swing up and down and drive the driving of one-level sprocket wheel 3 contrarotations realization bicycle; The people stands on that pushes pedals swings up and down it on the pedal 4, drives bicycle on the one hand and moves riding instead of walk effect of performance, and body-building function is brought into play in the simulation action of running on the other hand; Adopt the mode of secondary transmission; Strengthen the converter speed ratio between one-level sprocket wheel 3 and the trailing wheel 8, make that driving bicycle more exerts all one's effort, and has promoted the effect of body-building.
