Description
Art:
This utility model belongs to a kind of vehicles ridden instead of walk.
Background technology:
At present, known two-wheeled cycle has two kinds of gears than type of drive, and is all single-wheel stress: the first is that single the large gear turn the small gear rotates a kind of mode of trailing wheel stress；The second is that size gear ratio can be in the rear wheel drive mode changed.The combination of both bicycles is not the most good is exactly that rotating ratio brings up to good degree by the gear ratio of little to pedal spindle gear wheel and trailing wheel gear.And be all trailing wheel stress, and only trailing wheel energy stress, this single power force type bicycle, the driving force that only trailing wheel is delivered to by chain, become driving wheel.Front-wheel cannot only be become resistance wheel by the driving force of chain.
Summary of the invention:
In order to well overcome single-wheel force type two-wheeled cycle, not high enough and only trailing wheel stress the deficiency of the rotating ratio of size gear, this utility model provides a kind of double-wheel force type two-wheel variable-ratio two-wheeled cycle, well improve the rotating ratio of size gear, and front and back wheel stress simultaneously reaches variable-ratio purpose simultaneously.
This utility model solves the technical scheme that its technical problem is used: as a example by gear wheel with flywheel speed ratio 27 speed, and gear wheel uses 3 speed, and flywheel uses 9 speed.Pedal spindle the right and left gear wheel, rear flying wheel, the little gear of front-wheel, little gear on the right of one universal shaft structure left side flywheel, gear wheel synchronous interaction refers to pull out actuator, and flywheel synchronization linkage refers to pull out actuator, pull out before gear wheel, pull out after flywheel, the parts such as chain of same model.Pedal spindle the right and left gear wheel is same model；Universal shaft structure left side flywheel and rear flying wheel are same model；On the right of the little gear of front-wheel and universal shaft structure, little gear is same model.First a semicircular structure is done in the centre at direction cylinder Yu front fork, is contained in semicircular structure by universal shaft structure, and the central point of the compromise point of universal shaft structure and direction cylinder is on the same line；Universal drive shaft left end is fixed on vehicle frame, pulls out and be fixed on by universal drive shaft left end flywheel after flywheel, universal drive shaft left side flywheel with pull out after flywheel and pedal spindle left side gear wheel chain is connected on the same line.Universal drive shaft right-hand member is fixed on the fixed support of front fork and direction handle, and universal drive shaft right-hand member rotates with in the range of front-wheel and direction handle, and on the right of universal shaft structure, little gear gear little with front-wheel chain is connected on the same line.Pull out on the vehicle frame being fixed on rear flying wheel side after rear flying wheel, pull out after gear wheel and rear flying wheel and flywheel on the right of pedal spindle and connect on the same line by chain.Reach the purpose of variable-ratio double-wheel force simultaneously.The beneficial effects of the utility model are, reach front and back wheel stress and the purpose of front and back wheel variable-ratio simultaneously.Only increasing a universal shaft structure, gear wheel on prototype vehicle, pull out, pull out before gear wheel after flywheel, flywheel, gear wheel synchronizes to refer to pull out, and flywheel synchronization refers to pull out, simple in construction.
Accompanying drawing explanation
In Figure of description 1,1 is universal shaft structure figure, 2 is little gear graph on the right of universal drive shaft, 3 is universal drive shaft left side flywheel figure, 4 is the attachment structure figure of universal drive shaft, 5 is the direction that power rotates, although the power being delivered on universal drive shaft, direction is changed by the swing of universal drive shaft, but the power being delivered on universal drive shaft is unaffected, though the gear at two ends, universal drive shaft left and right differs, but being coaxial configuration, the different gear revolution equivalent right-hand member gear of left end flywheel exports the revolution of front wheel gear, because the little gear of front-wheel and the little gear of universal drive shaft right-hand member are same model.
It Figure of description 2 is this utility model schematic diagram.
Figure of description 3 is left side figure, the 1 gear wheel figure being integrally fixed on the pedal spindle of the left side in figure, and 2 is universal shaft structure figure, the fixed mount extended by the big frame of bicycle in terms of front shelters from, 3 is universal drive shaft left end flywheel figure, and 4 is to pull out figure after flywheel, and 5 is driving chain figure, 6 is the fixed mount figure of fixing universal drive shaft left end flywheel and vehicle frame, 7 is driving chain figure, and 8 is front-wheel figure, and 9 is trailing wheel figure, 10 is to pull out figure before the gear wheel of the left side, and 11 is that left and right gear wheel synchronous interaction refers to pull out actuator figure.
Figure of description 4 is right side figure, the 1 gear wheel figure being integrally fixed on the pedal spindle of the right side in figure, and 2 is little gear on the right of universal drive shaft, 3 is a semicircular structure, providing the position of universal drive shaft for convenience, 4 is driving chain, connects little gear on the right of the little gear of front-wheel and universal drive shaft, 5 is the reinforced liner figure of semicircular structure and direction handle, 6 is rear flying wheel figure, and 7 is driving chain figure, 8 be the right gear wheel before pull out figure, 9 is front-wheel figure, and 10 is that the linkage of before and after's flywheel synchronization refers to pull out actuator figure.
Current single-wheel force type two-wheeled cycle speed change straightgoing vehicle differs primarily in that with double-wheel force type two-wheel variable-ratio two-wheeled cycle；Single-wheel force type two-wheeled cycle speed change straightgoing vehicle, only single-wheel stress and only trailing wheel variable-ratio；And double-wheel force type two-wheel variable-ratio two-wheeled cycle, not only front and back wheel simultaneously stress, and front and back wheel can synchronous speed change simultaneously.
Detailed description of the invention
Below in conjunction with Figure of description and embodiment, this utility model is further illustrated:
In figure 3 with driving chain 5, connect universal drive shaft left end flywheel 3, and pedal spindle left side gear wheel 1, on the same line；Fixed mount 6 between fixing universal drive shaft left end and big frame fixes universal drive shaft left end.
In the diagram with driving chain 7, connect pedal spindle right-hand member gear wheel 1 and rear flying wheel 6, on the same line；The fixing little gear of universal drive shaft right-hand member fixes universal drive shaft right-hand member with the fixed mount 5 of semicircular structure with the fixed mount of the fixing little gear of universal drive shaft right-hand member with front fork, and universal drive shaft right-hand member rotates in the range of front-wheel with direction handle；With rotating link chain 4, linking the little gear of universal drive shaft right-hand member 2, gear 9 little with front-wheel is on the same line.
Structure successfully illustrates:
When rotating pedal spindle, pedal spindle left side gear wheel drives the little gear of universal drive shaft right-hand member through chain-driving universal drive shaft left end flywheel turns simultaneously, and the little gear of universal drive shaft right-hand member is through chain-driving front-drive.Gear wheel flying wheel after chain-driving in the pedal spindle right side drives rear wheel simultaneously,.Front and back wheel reaches to rotate the purpose of stress simultaneously.Before and after use, flywheel synchronization linkage refers to pull out actuator and left and right gear wheel synchronous interaction refers to that pulling out actuator carries out the regulation of gear ratio, reaches the purpose of two-wheel variable-ratio simultaneously.Reach the purpose of double-wheel force two-wheel variable-ratio.
