Description

Reversely riding bicycle

Technical field

The utility model relates to a kind of reversely riding bicycles, belong to vehicles non-motor vehicle technical field.

Background technique

Currently, bicycle be stepped on by manpower pedal it is foot-operated, drive rear wheel, then drive entire bicycle move ahead.It rides It is uncomfortable that it is easy fatigue during row, after especially riding over long distances, it is weary to be even more easy soreness of waist leg.

Utility model content

It the purpose of the utility model is to provide a kind of reversely riding bicycle, rides comfortable, coordination of body is reduced and damaged to human body Wound, more meets human muscle and moves force method, is firmly more convenient more comfortable.

Reversely riding bicycle described in the utility model, including intermeshing driving gear and driven gear, driving tooth Wheel is set on driving shaft, and both ends of main drive shaft is equipped with crank, and crank end is equipped with foot-operated；Driven gear is set on driven shaft, driven Axis is equipped with drive sprocket, and drive sprocket connects flywheel by driving chain, and flywheel is connect by rear axle with rear-wheel.

It is found by research repeatedly, human body is in riding, and foot steps down on foot-operated, and when pedaling forward, the sticking point of foot is inclined Farther out, the arm of force is long for the extended line downward from upper body, and waist stress can be made larger, be easy to cause the damage of waist, can also make thigh Outside it is muscular, become uncoordinated.Therefore, uncomfortable in riding, it especially rides for a long time over long distances, human body is easy tired Tire out, or even be easy to be damaged, especially waist.Pedaled after, the sticking point of foot near the downward extended line of upper body, body compared with Uprightly, small to the damage of waist, it kicks backward and walks with people, muscular exertion mode when running is closer, can more utilize human body Muscle naturally constitute ratio, strength can be bigger, and the figure of people also can more be coordinated.Biggish power can be easily issued, is relaxed Appropriateness greatly improves, also not subject to damage, protects human health.

The course of work or working principle：

Foot steps down on foot-operated, kicks backward, is engaged by driving gear with driven gear, reliable transmission, the transmission pedaled by after, Change direction, rear-wheel is driven to walk forward.

It is further preferred that the central point of driven gear is set to active shaft centre line place perpendicular and rear shaft center's line Between the perpendicular of place.Driving chain is set between driven gear and flywheel, driving chain without pass through driving gear, Transmission is more succinct, is less prone to transmission obstacle, is also less prone to failure.

It is further preferred that the line of driven shaft and driving shaft, the line with driving shaft and rear axle, angle be not more than 60 Degree.

It is further preferred that driving gear is roller gear driving gear, driven gear is roller gear driven gear.It nibbles More reliable, reliable transmission is closed, failure is less prone to, reduces maintenance.

It is further preferred that driving gear, by active bearings connecting bracket, driven gear passes through driven bearing connection branch Frame.

It is further preferred that rear axle passes through rear bearing connecting bracket.

Compared with prior art, the utility model has the beneficial effects that：

The utility model is converted into line direction before rear-wheel by setting driving gear and driven gear, the transmission pedaled by after, Driving gear and driven gear engagement, realize stable turning transmission, pedal forward technical problem after solving bicycle, solve It forward pedals and to ride uncomfortable or even be easy the technical issues of being damaged；

Before pedal, the sticking point of foot deviates the downward extended line of upper body farther out, and the arm of force is long, and waist stress can be made larger, is easy The damage of waist is caused, the muscular of big leg outer side can be also made, becomes uncoordinated.Therefore, uncomfortable in riding, it is especially long Distance is ridden for a long time, and human body is easy tired, or even is easy to be damaged, especially waist；

It is pedaled after, for the sticking point of foot near the downward extended line of upper body, body is more upright, and it is small to the damage of waist, It kicks backward and walks with people, muscular exertion mode when running is closer, more can naturally constitute ratio, power using the muscle of human body Amount can be bigger, and the figure of people also can more be coordinated.Biggish power can easily be issued, comfort level greatly improves, also not vulnerable to Human health is protected in damage.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of an embodiment of the utility model,

Fig. 2 is the right view of Fig. 1.

In figure：1, driving gear 2, driving shaft 3, crank 4, foot-operated 5, rear-wheel 6, flywheel 7, rear axle 8, transmission chain Item 9, drive sprocket 10, driven shaft 11, driven gear 12, bracket 13, vehicle seat 14, handlebar 15, front-wheel 16, driven shaft Hold 17, active bearings.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, to the technical scheme in the embodiment of the utility model make into One step is clearly and completely described：

Embodiment 1

As shown in FIG. 1 to FIG. 2, reversely riding bicycle described in the utility model, including 1 He of intermeshing driving gear Driven gear 11, driving gear 1 are set on driving shaft 2, and 2 both ends of driving shaft are equipped with crank 3, and 3 end of crank is equipped with foot-operated 4；From Moving gear 11 is set on driven shaft 10, and driven shaft 10 is equipped with drive sprocket 9, and drive sprocket 9 connects flywheel by driving chain 8 6, flywheel 6 is connect by rear axle 7 with rear-wheel 5.

Embodiment 2

As shown in FIG. 1 to FIG. 2, on that basis of example 1, the central point of driven gear 11 is set to 2 center line institute of driving shaft Where 7 center line of perpendicular and rear axle between perpendicular.Driving chain is set between driven gear and flywheel, transmission For chain without pass through driving gear, transmission is more succinct, is less prone to transmission obstacle, is also less prone to failure.

Embodiment 3

As shown in FIG. 1 to FIG. 2, on the basis of embodiment 2, the line of driven shaft 10 and driving shaft 2, with driving shaft 2 with after The line of axis 7, angle be not more than 60 degree.More compact structure, reliable transmission.
