Abstract
The present invention is bidirectional bicycle driving unit, and belongs to the field of bicycle technology. The bidirectional bicycle driving unit includes double chain wheel including inner chain wheel and outer chain wheel coaxially set for sync rotating, double flywheel including inner flywheel and outer flywheel with coaxially set monodirectional clutches, the first chain for connecting the inner chain wheel and the inner flywheel, chain holding wheel on its rack, chain leader with guiding chain wheel, the second chain connecting the outer chain wheel, the outer flywheel, the guiding chain wheel and the chain holding wheel. The back wheel is driven through the first chain when the chain wheel crank runs clockwise, or through the second chain when the chain wheel crank runs counterclockwise. The present invention makes it possible for the bicycle to run through treading in either forward direction or back direction.
Description
Technical field
The present invention relates to a kind ofly, can realize that especially example steps on the bicycle driving device of riding and going ahead from horizontal drive device.
Background technology
At present, be disconnected today of improving in material life, people are more and more higher to the care of health, the gymnasium can provide the condition of taking exercises, but arduous one day of workman, the peasant worked hard one, and students is made great efforts hard study especially constantly, health is all very tired out, and not free and energy removes behaviour's habit fitness equipment every day.
In recent years, " left handed " pioneer does the inverted sequence motion together from falling away, draw, hang upside down to appeal in the tree people, during the medical research table, the inverted sequence motion is to lunar, few cloudy, the cloudy left and right sides six YIN meridians of fainting has good operational effect, make the qi and blood balance, can temper people's cerebellum again, multinomial function such as developing right brain.Chinese patent discloses the sporting car that a key name is called a kind of crank motion scooter engine installation and uses this engine installation, application number is 200420039802.5, though it has realized the motion of bicycle inverted sequence, but because its structure is limit, this kind technology can't be used on the less bicycle in wheel footpath, otherwise can cause transmission device and ground to bump.
Summary of the invention
In order to overcome prior art the shortcoming of existence is arranged, the invention provides a kind of bidirectional bicycle driving unit, this device not only can make bicycle travel by normal custom, can also travel by stepping on, and can be applicable on the various bicycles, and comformability is stronger.
Bidirectional bicycle driving unit of the present invention, comprise sprocket wheel that is arranged on the bicycle middle shaft and the flywheel that is arranged on the hind axle, be connected by driving chain between sprocket wheel and the flywheel, it is characterized in that, described sprocket wheel is made up of coaxial synchronous inner sprocket that fixedly installs and outer sprocket wheel, and described flywheel is made up of with outer flywheel the interior flywheel of coaxial setting; Be provided with first free-wheel clutch between the hind axle at interior flywheel and place; Be provided with second free-wheel clutch identical between the hind axle at outer flywheel and place with the first free-wheel clutch direction; Inner sprocket is connected by first chain with interior flywheel; Be fixed with the chain cable fairlead support on the vehicle frame of hind axle, chain cable fairlead is established in this chain cable fairlead support back upper place, and the below is provided with the fairleader of band fairleader sprocket wheel, and second chain is connected between outer sprocket wheel, outer flywheel, fairleader sprocket wheel, the chain cable fairlead.
When the common mode cw of sprocket crank was just gone, inner sprocket, interior flywheel be by just going i.e. first chain drive of chain, and outer flywheel rotated counterclockwise and skidded this moment, step on chain promptly second chain along with rotation but do not drive trailing wheel.When sprocket crank rotated counterclockwise, interior flywheel rotated counterclockwise and skids, and first chain is along with rotating but do not drive trailing wheel, second chain under the outer flywheel action that clockwise rotates, the direct drive trailing wheel.
The invention has the beneficial effects as follows, bicycle is travelled by normal custom, can also travel by stepping on, can be applicable on the various bicycles, comformability is stronger.Often both forward and reverse directions is ridden, and helps healthy.

The specific embodiment
As shown in Figure 1.Bidirectional bicycle driving unit comprises the two strands wheel that is arranged on the bicycle middle shaft and is arranged on round trip flight wheel on the hind axle, is connected by driving chain between corresponding sprocket wheel and the flywheel.
Described double-stranded wheel is made up of coaxial inner sprocket that fixedly installs 22 and outer sprocket wheel 21, and inner sprocket 22 and outer sprocket wheel 21 rotate synchronously in the same way, and size is identical.
Described round trip flight wheel is made up of with outer flywheel 31 the interior flywheel 32 of coaxial setting; Be provided with first free-wheel clutch between the hind axle 8 at interior flywheel 32 and place; Be provided with second free-wheel clutch between the hind axle at outer flywheel and place, first free-wheel clutch is identical with the second free-wheel clutch action direction, and promptly having only could drive wheels when rotating in the clockwise direction.
Inner sprocket is connected by just capable chain 5 (first chain) with interior flywheel.On the vehicle frame of hind axle 8, be fixed with chain cable fairlead support 6, chain cable fairlead 7 is established in these chain cable fairlead support 6 back upper places between chain cable fairlead support 6 and guide wheel brace panel 9, the below is provided with the fairleader 10 of band fairleader sprocket wheel, fairleader 10 is provided with fairleader sprocket wheel 71, stepping on chain 4 (second chain) is connected between outer sprocket wheel, outer flywheel, fairleader sprocket wheel, the chain cable fairlead, step on that flywheel is outside the outer encirclement form except the chain 4, all the other are interior encirclement form, mainly are to change outer flywheel rotation direction.
As Fig. 2, Fig. 3.Hind axle 8 is arranged in the notch of chain cable fairlead support 6, and fastener is fixed on the vehicle frame 1 by the chain cable fairlead support hole 11 that connects to ground.Fairleader structure on the structure of fairleader 10 and the existing variable speed bicycle is basic identical.
When sprocket crank 12 common mode cws were just gone, inner sprocket 22, interior flywheel 32 be by just going i.e. first chain drive of chain, and outer flywheel 31 rotated counterclockwise and skidded this moment, step on chain promptly second chain along with rotation but do not drive trailing wheel.When sprocket crank rotated counterclockwise, interior flywheel rotated counterclockwise and skids, and first chain is along with rotating but do not drive trailing wheel, second chain under the outer flywheel action that clockwise rotates, the direct drive trailing wheel.
