Abstract
The utility model relates to an assistant accessory for a bicycle, particularly to an inertia energy storage booster for a bicycle, comprising a flywheel type unidirectional clutch arranged on a central shaft of the bicycle, wherein the flywheel type unidirectional clutch is connected with an external hung inertia wheel device by a transmission device. Compared with the prior art, the inertia energy storage booster for the bicycle has the advantages of reasonable design, simple structure, convenient installation, process difficulty reduction of a bicycle body, low processing cost and the like.
Description
Technical field
The utility model relates to a kind of bicycle auxiliary accessories, and a kind of bicycle inertia energy storage servo-unit specifically is provided.
Background technology
Under the prior art, the auxiliary accessories that a kind of bicycle is arranged, it can provide energy storage power-assisted help for bicycle, application number provides a kind of body structure coaxial with bicycle middle shaft (as shown in Figure 1) for 200810192035.6 patent of invention, be that bicycle middle shaft and inertia wheel and driving system are installed on the bicycle bottom bracket position simultaneously, this need be with the bicycle bottom bracket enlarged-diameter to more than the 150MM, and needs the eccentric position above right end cap that transmission excess axle and bearing are installed.Above structure causes following problem: frame five-through is excessive, and the bicycle center of gravity changes, and not attractive in appearance; Cycle frame as the benchmark location, after the oversize change of five-way, causes the original production technology of vehicle frame and original production facilities also need do bigger change with five-way, and productive costs is too high, is difficult for realizing batch manufacturing; Right end cap eccentric position working accuracy height, processing is big, cost is high.
In addition, application number is 200810192035.6 patent of invention design employing secondary gear transmission, wherein also has one-level transmission group knocking in the casing outside, and the two-stage driving efficiency is not high relatively, and case external gear poor lubrication is fragile.
Summary of the invention
The utility model is at above deficiency, provide a kind of reasonable in design, simple in structure, easy for installation, reduce vehicle body technology difficulty, bicycle inertia energy storage servo-unit that tooling cost is low.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of bicycle inertia energy storage servo-unit comprises the flywheel-type free-wheel clutch that is arranged on the bicycle middle shaft, and described flywheel-type free-wheel clutch is connected with external hanging type inertia wheel device by driving device.
External hanging type inertia wheel device comprises the inertia wheel casing that is arranged on the cycle frame, is provided with inertia wheel in the described inertia wheel casing, and the axle drive shaft of described inertia wheel connects described bicycle middle shaft by described driving device.
Driving device comprises the sprocket wheel that is arranged at described bicycle middle shaft, and sprocket wheel connects the axle drive shaft of described inertia wheel by chain.
A kind of bicycle inertia energy storage servo-unit of the present utility model, adopt external hanging type inertia wheel apparatus structure, this structure does not change the position and the size of bicycle bottom bracket, the inertia wheel casing is placed on the center frame that axle drive shaft is assemblied in casing links to each other of five-way top, inertia wheel, the utlity model has following advantage: adopt the assembly relation and the position of standard Middle shaft assembly, each parts of car body not to change; Inertia wheel axle drive shaft working accuracy is easy to guarantee and the car load good looking appearance; Manufacturability and manufacturing equipment to vehicle frame do not have new requirement, realize that easily industrialized mass production, cost are low.
And the utility model only needs the one-level transmission to meet the demands, and driving efficiency can reach more than 98%, and selects fine pith chain-driving, reliability height for use, and volume is little, good weatherability and cost are low, and assembly technology is simpler.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the position erection plan of the bicycle inertia energy storage servo-unit under the prior art;
Fig. 2 is the position erection plan of a kind of bicycle inertia energy storage servo-unit of the present utility model;
Fig. 3 is the structural representation of a kind of bicycle inertia energy storage servo-unit of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.
Provide a most preferred embodiment below:
A kind of bicycle inertia energy storage servo-unit comprises the flywheel-type free-wheel clutch 2 that is arranged on the bicycle middle shaft 1, and described flywheel-type free-wheel clutch 2 is connected with external hanging type inertia wheel device 3 by driving device.
External hanging type inertia wheel device 3 comprises the inertia wheel casing 32 that is arranged on the cycle frame 31, is provided with inertia wheel 33 in the described inertia wheel casing 32, and the axle drive shaft 34 of described inertia wheel 33 connects described bicycle middle shaft 1 by described driving device.
Driving device comprises the sprocket wheel 4 that is arranged at described bicycle middle shaft 1, and sprocket wheel 4 connects the axle drive shaft 34 of described inertia wheel 33 by chain 5.
Adopt the utility model when treadled cycle, promptly drive two groups of moment driving systems simultaneously, one group is connected the direct drive trailing wheel with bicycle rear and advances the effect that another group driving inertia wheel 33 plays energy storage and releases energy.Experiment showed, under inertia wheel 33 most of situations it is that the energy of the non-useful work of doing is collected and stored when riding, very little to the consumption of propulsive effort; When the power that drives trailing wheel during less than force of inertia, high speed inertia energy storage device releases energy immediately provides power for trailing wheel.Move in circles by this, thereby improved manually driven efficient, make ride legpower evenly, steadily, effect obviously laborsaving, speedup arranged.
Above-described embodiment, the utility model specific embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.
