Description
Technical field
The utility model belongs to technical field of bicycles, especially a kind of bicycle that utilizes gravity to quicken.
Background technology
In the prior art, the kind of bicycle is a lot of, but changes aspect power not quite, and foot-operated and chain wheel all is arranged on the axis, and the cyclist also gives trailing wheel by chain with transmission of power by chain wheel simultaneously with the foot-operated power that produces.Its defective mainly is that the people had both produced power when riding downward exerting oneself, and its body weight also produces resistance, and is firmly big more, and the resistance that is produced also strengthens simultaneously.
Summary of the invention
The purpose of this utility model is: a kind of bicycle that utilizes gravity to quicken is provided, it has changed the structure of power pack section, is divided into different positions with foot-operated with chain wheel, makes the gravity adding that also cyclist is produced foot-operated the time, make bicycle running quicker, more laborsaving.
The purpose of this utility model is achieved in that this gravity acceleration bicycle is the same with common bicycle general structure, by the foot-operated power that produces, driving the chain drive trailing wheel by the chain wheel on the axis advances, also contain vehicle frame and power part, its special feature is: ride and separate with sprocket wheel (chain wheel), foot-operated being arranged on the drive sprocket axle 12, chain wheel is arranged on the axis 16; Be provided with the dynamic structure that utilizes gravity to quicken at the rear portion of vehicle frame, this dynamic structure is cooperatively interacted by driving wheel 13, power wheel 11, locating wheel 9,14 and gravity supporting rod 17 and flexible connection dish 10 etc. and forms, driving wheel 13 is arranged on the interior circle of power wheel 11 and with the interior circle of power wheel and contacts, and is that wipe contact or gear contact between driving wheel 13 and the power wheel 11.Drive sprocket axle 12 and gravity supporting rod 17 and foot-operated linking to each other, the strut member 4 under gravity supporting rod 17 and the vehicle seat 3 joins by flexible connection dish 10, and flexible connection dish 10 connects vehicle seat strut member 4 and gravity supporting rod 17 by the bearing pin connection mode.The cylindrical of power wheel 11 and three locating wheel 9,14 mutual toe joints, one of them locating wheel 14 and axis power wheel 15 are toe joint mutually, and the chain wheel on the axis 16 links to each other with trailing wheel by chain.
The utility model design is ingenious, simple in structure, can be applicable to the bicycle of plurality of specifications model, and the gravity that it utilizes body weight to produce quickens to bicycle, and the change resistance is power.This car can be used as the vehicle, and tool movement also can be used as transportation means, has popularizing application prospect widely.
Description of drawings
Accompanying drawing 1 is the utility model bicycle part-structure scheme drawing;
Accompanying drawing 2 is the part enlarged diagram of accompanying drawing 1;
Accompanying drawing 3 is the A-A cross-sectional view of accompanying drawing 1.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.As shown in Figure 1, bicycle of the present utility model and ordinary bicycle profile and the equal broadly similar of structure, the shown just part-structure of car among Fig. 1 for the ease of understanding its inner structure, has omitted among the figure as parts such as foot-operated, chain wheels.The maximum characteristics of this bicycle are to be provided with the structure that power quickens, to ride with chain wheel for this reason and separate, ride and link to each other with drive sprocket axle 12, and chain wheel links to each other with axis 16, pass to power wheel 11 by the foot-operated power that produces via driving wheel 13, foot-operated power can make driving wheel 13 slightly lift forward, and the gravity of human body also is passed to driving wheel 13 wheel 11 runnings of driving up by gravity supporting rod 17, reaches gravity thus and quickens.As shown in Figure 3, power wheel 11 is formed by three layers, in the middle of it is toothed disc 19, respectively there is a platen 20 both sides of toothed disc 19, three-layered node is integrated, its interior justifying is provided with a rubber ring in the accompanying drawing 3, is wipe contact with justifying contacted driving wheel 13 in it, and they can also be gear contact (not shown).As shown in Figure 2, three locating wheels 9,14 are located power wheel 11, driving wheel 13 contacts with the interior circle of power wheel 11, driving wheel 13 drives by bonded assembly on the drive sprocket axle 12 is foot-operated, and gravity supporting rod 17 also is connected with drive sprocket axle 12 and quickens its running for power wheel 11 weight transfer of human body.Driving wheel 13 promotes power wheel 11 motions, to on the axis power wheel 15 on the axis 16, power wheel 15 drives the axis running to location power wheel 14 with transmission of power, and chain wheel is arranged on the axis 16, chain wheel passes to trailing wheel 8 by chain with kinetic energy, and bicycle is promptly advanced forward.Flexible connection dish 10 is movably connected vehicle seat strut member 4 and gravity supporting rod 17 in the bearing pin mode, when the human masterpiece is used for riding, driving wheel 13 is slightly upwards risen, and this moment, human body gravity also acted on driving wheel 13, played the effect of wheel 11 runnings of driving up.
Be a kind of embodiment of the present utility model shown in the accompanying drawing, the utility model is not to have only this a kind of array mode, and according to the difference of vehicle and vehicle frame shape, the relative block position of each parts can be provided with separately, but the principle of effect is constant.
