Abstract
The utility model belongs to a bicycle wheel, particularly a reversing vane type boosting bicycle wheel. The utility model is mainly provided with a wheel ring, a wheel hub and a plurality of wheel spokes. The utility model is characterized in that the outer part of the concave surface of each wheel spoke is provided with an additional vane which can swing in an oriented method, the cross section of each additional vane is of an approximate crescent shape, both end heads of each additional vane are provided with pin holes which are respectively spliced with pin shafts on the wheel ring and the wheel hub, the shape of the convex surface of each additional vane tallies with and is corresponding to the shape of the concave surface of each wheel spoke, and the convex surface of each additional vane keeps a certain gap with the concave surface of each wheel spoke. The utility model has the advantages that the wheel ring is provided with an additional vane which can swing in an oriented method, when people riding bicycles encounter alternating wind directions, the additional vanes installed on the outer sides of the wheel spokes of bicycles swing along wind directions and likewise generate additional force moment which causes wheels to forwards roll, thereby, the utility model completely changes air resistance force into auxiliary force and really reaches the purpose for saving the physical strength of people.
Description
Technical field
The utility model belongs to cycle wheel, relates in particular to a kind of commutation fan blade type morpet wheel.
Background technology
Bicycle has been subjected to generally liking of people as a kind of light walking-replacing tool, the vehicle of using always the most when China town and country people go on a journey especially.Modern bicycle performance becomes better and approaching perfection day by day, and moulding is more attractive in appearance.Laborsaving for the bicyclist is ridden, released electronic or pneumatic bicycle on the market.The disclosed technology of inventor's Granted publication CN2414929Y, a kind of wind-force power-assist is ridden wheel, is that cross-sectional plane is similar to meniscate bounce-back formula blade and makes its convex surface roll direction before wheel with the spoke design of riding wheel.Technique scheme can become power-assisted to air resistance, makes the bicyclist save muscle power.But when the bicycle of using above-mentioned technology ran into the conversion wind direction when riding, bounce-back formula blade can produce additional resistance to the wheel that preceding rolls, and riding speed is reduced.
The utility model content
Main purpose of the present utility model is to overcome above-mentioned technological deficiency, and provide a kind of commutation fan blade type morpet wheel, promptly be provided with orientable swing additional blades outside the bounce-back formula blade on being installed on bicycle, produce too when when the bicyclist rides, running into the alternation wind direction like this and make the additional moment that rolls before the wheel, thereby realize that fully the changing air resistance is a power-assisted, real reaching effectively makes the bicyclist save the purpose of muscle power.
For realizing the purpose of this utility model, the technical scheme that adopts is, a kind of commutation fan blade type morpet wheel, mainly contain wheel rim, wheel hub and a plurality of spoke, wheel rim is equipped with tire outward, spoke is fixed between wheel rim and the wheel hub and rectangular distribution radially, the spoke cross section is approximate crescent, its convex surface rolls direction before wheel, it is characterized in that: the spoke concave surface is inclusive with the additional blades of orientable swing outward, its additional blades cross-sectional plane is similar to crescent, its additional blades two ends is provided with pin-and-hole and pegs graft with the bearing pin that is arranged on wheel rim and the wheel hub respectively, the convex surface of additional blades and spoke concave are coincide corresponding, between the convex surface of its additional blades and the spoke concave surface and keep certain interval.
Described blade oscillating angle is 2 °-5 °.
Described blade inside face is provided with a slice or the above wind wing of a slice of vertical concave surface.
The beneficial effects of the utility model are: its wheel rim is provided with orientable swing additional blades, when when the bicyclist rides, running into the alternation wind direction, the additional blades that makes it to be installed in the bicycle spoke outside is swung along wind direction, produce too and make the additional moment that rolls before the wheel, thereby realize that fully the changing air resistance is a power-assisted, really reach make the bicyclist save muscle power purpose.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
Please refer to Fig. 1-2, a kind of commutation fan blade type morpet wheel, mainly contain wheel rim 1, wheel hub 2 and a plurality of spoke 3, wheel rim is equipped with tire 4 outward, spoke 3 is fixed between wheel rim 1 and the wheel hub 2 and rectangular distribution radially, spoke 3 cross sections are approximate crescent, its convex surface rolls direction before wheel, spoke 3 concave surfaces are inclusive with the blade 5 of orientable swing, described blade 5 cross-sectional planes are similar to crescent, its two ends is provided with pin-and-hole 7 and pegs graft with the bearing pin 6 that is arranged on wheel rim and the wheel hub respectively, and the convex surface of blade 5 coincide corresponding with the spoke concave surface and keeps certain interval.The angle of the concave surface limit blade reciprocally swinging of spoke is 2 °-5 °.The blade inside face is provided with a slice or the above wind wing 8 of a slice of vertical concave surface, can absorb wind-force and become power-assist power.During installation, utilize the plasticity of blade that blade is plugged in the pin-and-hole.No matter be that the swing of blade box haul can produce and make the additional moment that rolls before the wheel with the wind, against the wind or crosswind or alternation wind direction.The utility model is specially adapted to various manpower wheels such as bicycle, three-wheel vehicle.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
Claims (3)
1, a kind of commutation fan blade type morpet wheel, mainly contain wheel rim, wheel hub and a plurality of spoke, wheel rim is equipped with tire outward, spoke is fixed between wheel rim and the wheel hub and rectangular distribution radially, the spoke cross section is approximate crescent, its convex surface rolls direction before wheel, it is characterized in that: the spoke concave surface is inclusive with the additional blades of orientable swing outward, its additional blades cross-sectional plane is similar to crescent, its additional blades two ends is provided with pin-and-hole and pegs graft with the bearing pin that is arranged on wheel rim and the wheel hub respectively, the convex surface of additional blades and spoke concave are coincide corresponding, between the convex surface of its additional blades and the spoke concave surface and keep certain interval.
