Abstract
The said bicycle has an eccentric wheel-linkage transmission machanism without chain, chain wheel, and toothed free wheel. Similar to common bicycle, it is foot pedaling driven. The said bicycle is simple in structure, low in cost and low in vibration and is firm and durable in that it is dissimilar to common bicycle, which has much failure trouble caused by worn chain, chain wheel and free wheel. The said structure may be also used in tricycle and motorcycle.
Description
What the present invention relates to is a kind of chain-less linkage-driven bicycle.Since bicycle occurring in the world, chain, sprocket wheel, flywheel teeth have all been be unable to do without.Easy to wear and the frequent et out of order of this structure, complex process cost height simultaneously.
According to reports, the Nanchang City, Jiangxi Province has a people to invent chain-less bicycle, is the way that adopts gearing shaft.But, do not obtain promoting because of making and reasons such as the assembly technology requirement is high, vibration is big, cost height.
For this reason, the present invention provides a kind of chain-less linkage-driven bicycle at above-mentioned various defectives exactly.Have that structural manufacturing process is simple, cost is low, advantage such as firm and durable, vibration are little.
The present invention does not still have China and foreign countries, is the major reform of the drive mechanism of bicycle power, and is rising.
Maximum feature of the present invention is to utilize the interlock of eccentric shaft and connecting rod to reach the transmission of power.
The transmission principle of this power is provided by following two accompanying drawings and two embodiment.
Figure one is rotary-type constructional drawing.
Figure two goes up the mo(u)ld bottom half constructional drawing.
Among the figure:
1, the outer dish 5 in back, shroud 9, reverse lever
2, back inner disc 6, pre-eccentric axle 10, commutation hole
3, back eccentric shaft 7, right handle 11, commutation pin
4, connecting rod 8, right pedal
Embodiment one: rotary-type
Form by the outer dish in back (1), back inner disc (2), back eccentric shaft (3), connecting rod (4), shroud (5), pre-eccentric axle (6), right handle (7).
Between outer dish in back (1) and the back inner disc (2), still be the inner structure of freewheel, promptly unidirectional rotation drives.Having a fixing back eccentric shaft (3) to live with the metapore of connecting rod (4) outside the back on the dish (1) connects.
Rear axle is at trailing wheel floral disc axial location, and both are welded into a whole, and back inner disc (2) tightly connects with rear axle.Like this, trailing wheel, rear axle, hub disk (1,2) become one, and can together rotate.
Between the rear axle after shaft relief behind the vehicle frame and the above-mentioned repacking bearing is arranged, its outer garden just is fixed on the vehicle frame, thereby trailing wheel, rear axle, hub disk also are fixed on the vehicle frame simultaneously.
Shroud (5) tightly connects with the axis of vehicle frame, and the front and rear gaps of connecting rod (4) is lived with front and back two eccentric shafts (6,3) respectively and connected (available bearing).Two dishes (5,1,2) are just realized interlock by connecting rod (4) like this.
Note, require in distance and dish (5,1,2) two, front and back at front and rear gaps two centers of connecting rod (4) distance in the heart should equate that two eccentric arms of front and back eccentric shaft (6,3) also should equate.
Tighten at pre-eccentric axle (6) and to connect the right handle (7) of ■ (its axially with shroud (5) radially consistent), (interior) holds the installation right pedal outside right handle (7), the handle on the left side, pedals the same with ordinary bicycle.
Like this, bipod is the same with stepping on ordinary bicycle, with the rotation mode reinforcing, and shroud (5) rotation, through the interlock effect of connecting rod (4), front and back eccentric shaft (6,3), hub disk (1,2) also rotates, and trailing wheel is and then rotation also, and bicycle has just advanced.
Embodiment two: go up mo(u)ld bottom half.
Structure as figure two needs two covers, installs in the vehicle frame left and right sides respectively.Hub disk (1,2) and connecting rod (4) are just the same with precedent, have just used reverse lever (9) instead at vehicle frame axis place.Live with axis and connect (available bearing) in commutation hole (10), commutation pin (11) also is to live in connecting (available bearing) with the preceding hole of connecting rod (4).
Step on a left side (right side) pedal that is installed on the reverse lever (9) so up and down, the trailing wheel rotation is advanced.
Notice that two distances between centers of commutation hole (10) and commutation pin (11) are greater than the eccentric arm of back eccentric shaft (3) at least.This value is bigger, and the up-and-down movement amplitude of pin is just little, needs to obtain comfortable numerical value through test.
The present invention also can be applicable to motor bike, three-wheel vehicle.
Please Patent Office of the People's Republic of China entrust China Bicycle Plant to implement, be rising.
Claims (7)
1, a kind of chain-less linkage-driven bicycle, it is characterized in that the outer dish in back: be still the freewheel inner structure between (1) and the back inner disc (2), promptly unidirectional rotation drives.
2, according to claim 1, it is characterized in that a fixing back eccentric shaft (3) is arranged on the outer dish in back (1), living with the metapore of connecting rod (4) connects.
3,, it is characterized in that the forward and backward hole on the connecting rod (4) connects (available bearing) with forward and backward eccentric shaft (6,3) is alive respectively, to reach the purpose of interlock according to claim 1.
4, according to claim 1, it is characterized in that having on the shroud (5) a fixing pre-eccentric axle (6), it is lived with the preceding hole of connecting rod (4) and connects.
5,, it is characterized in that pre-eccentric axle (6) is tightly connecting right handle (7) according to claim 1.
6, according to claim 1, it is characterized in that having on the reverse lever (9) a commutation hole (10), can on axis, rotate.
7, according to claim 1, live and connect in it is characterized in that commutating pin (11) and the preceding hole of connecting rod (4).
