Abstract

The utility model relates to a body building bicycle, which is characterized in that a left disk chuck 1 is connected to a bicycle middle axle 2; the end parts of bicycle frames 4 and 11 are separately provided with a support plate 5 and a bearing seat which is connected to the support plate; a flywheel axle 8 is connected inside the bearing seat; one end of the flywheel axle 8 is connected with a left flywheel 7 which is connected with the left disk chuck 1 by a chain 3 for transmission; the other end of the flywheel axle is connected with a gear 8 which is meshed with a gear which is arranged on a back-axle spline drum for transmission. The body-building bicycle can cause the bicycle to go forward by both forward and reverse pedaling by people. On one hand, the physical strength of people is utilized sufficiently. Both of the forward speed and the distance of the bicycle obtain great increase. On the other hand, the fatigue symptoms of a leg part, a rump, a waist, and an abdomen of people can be relieved by reverse pedaling, and the body-building bicycle also has body-building function to a corresponding extent. The blood vessel of a heart and a brain and a nervous system of people obtain sufficient exercise.

Description

Body-building bicycle

Technical field: the utility model relates to the vehicle, particularly a kind of bicycle with body-building function.

Background technology:

Bicycle is used widely in worldwide at present because of it has advantage simple in structure, as not need the energy, clean environment firendly, and it not only can be used as walking-replacing tool to alleviate congested traffic condition, can also be as fitness tool.The basic structure of bicycle is that front and back wheel is installed on the vehicle frame two ends, front-wheel is connected with handlebar, the right flywheel that connects transmission on the hind axle, it is connected cooperation by chain with right floral disc on being coupled to axis, be that manpower steps stretcher when flywheel is just being changeed, flywheel drives trailing wheel just to be changeed wheel is rolled forward, when the flywheel reversing or when not changeing then with respect to wheel slipping.So, ride an end distance when feeling fatigue when people's forward, always stop to scrunch or reverse scrunching with the alleviating fatigue state.But reversing scrunches the power that does not produce forward, and this part power is not fully utilized in other words, and people also can not have the reversing of active consciousness and long period to scrunch to ride.Extensively retrieve at the problems referred to above, still find no solution related to the present invention.

Summary of the invention:

The purpose of this utility model is exactly in order to solve the above-mentioned defective that exists in the prior art and a kind of forward and reverse body-building bicycle that can forward moves ahead that scrunches of design-calculated.

To achieve these goals, the utility model has adopted following technical scheme:

A kind of body-building bicycle, it is made up of vehicle frame and institute's bonded assembly front and back wheel, be associated with axis on the vehicle frame, be associated with right floral disc on the axis, be associated with right flywheel on the hind axle, right floral disc is connected transmission with right flywheel by chain, it is characterized in that connecting on the described axis a left floral disc, the vehicle frame end is provided with stay bearing plate and connection bearing seat thereon, be associated with a flywheel shaft in the bearing seat, flywheel shaft one end connects a left flywheel, and it is connected transmission by chain with left floral disc, the other end of flywheel shaft connects a gear, it and the meshed transmission gear that is arranged on the hind axle Decorative drum.Original right flywheel also can be installed on the left side of rear axle, connects in newly-increased stay bearing plate and the connection bearing seat, bearing seat thereon that bonded assembly left side flywheel also can be installed on the right on flywheel shaft, the flywheel shaft, and its effect is the same.

Because the utility model has adopted technique scheme, make people's forward pedaling or backward pedaling bicycle all walk forward, this makes people's muscle power be fully utilized on the one hand, the speed that bicycle moves ahead, distance are all significantly increased; On the other hand reversing scrunch not only shank, buttocks, waist and belly that can ease people fatigue symptom, can also have the body building function of certain degree, walk just as people's backward, people's cardiovascular and cerebrovascular, nervous system are taken exercise fully.

For the utility model is described in further detail, following accompanying drawing provides a most preferred embodiment of the present utility model.

Description of drawings:

Fig. 1 is a front view of the present utility model;

Fig. 2 is the A-A cutaway view of Fig. 1;

The specific embodiment:

As Fig. 1, shown in Figure 2, the utility model is to convert on the basis of original bicycle, promptly the left end at former bicycle middle shaft 2 is provided with a left floral disc 1, at the hypotenuse 4 of vehicle frame rear end and stay bearing plate 5 of infall welding of straight flange 11, bearing seat 8c of welding on the stay bearing plate 5, two bearing 8a and axle sleeve 8b wherein are set, bearing 8a goes up and connects a flywheel shaft 8, the flywheel shaft left end connects a left flywheel 7, it is connected transmission by chain 3 with left floral disc 1, the other end of flywheel shaft connects a gear 6, it and gear 9 engaged transmission that are arranged on the hind axle Decorative drum 10.Its working process is as follows: when normally riding forward, right flywheel 10a is just changeing and drives bicycle rear and just changeing and move ahead, and left flywheel 7 was in idle running or did not change state with respect to trailing wheel through the conversion of gear 10,6 this moment; When the backward pedaling stretcher, left flywheel 7 is in the real-turn state, and the conversion through gear 6,10 also makes bicycle rear be in the forward traveling that is just changeing, and right flywheel then is in idling conditions.
