Abstract
The utility model relates to a two-person easy-amusement bicycle, comprising front and back wheels, front and back seats, front and back handlebars, front and back large wheel discs, a back center axle flywheel, a back wheel hub flywheel, a supporting beam and a connecting chain. The back center axle is provided with a composite transmission mechanism, and both sides of the back wheel hub are respectively provided with two flywheels; the two flywheels of the composite transmission mechanism are respectively connected with the flywheel of the front large wheel disc and the flywheel at one side of the back wheel hub through the chain, and the flywheel at the other side of the back wheel hub is connected with the back large wheel disc through the chain. The back large wheel disc is used to transmit the motion of a back rider through the chain and the flywheel at one side of the back wheel hub, the front large wheel disc is used to transmit the motion of a front rider through the chain and the two flywheels of the back center axle and the flywheel at the other side of the back wheel hub, and the two motions are mutually independent. Since the back center axle is designed with the composite transmission mechanism, the difficulty of two-person ride is decreased; the other person can rest when one person rides, and two persons can drive simultaneously; easy-amusement performance is increased, and the two-person easy-amusement bicycle is applicable to long distance travel.
Description
One. technical field: the utility model relates to a kind of tandem bicycle, particularly relates to a kind of double amusement and recreation bicycle.
Two. background technology: well-known, bicycle is the walking-replacing tool the most widely that present Chinese family uses, and along with improving constantly of people's living standard, and China's holiday system is perfect, and people are also more and more higher for the requirement of amusement and leisure.Bicycle is as using the most general vehicle, how to make its ride instead of walk and amusement and recreation in one, be the purpose of this utility model.Present tandem bicycle requires two bicyclists that the conformability of height is arranged, thereby has increased the difficulty of riding owing to adopt the chain synchronous drive mechanism, lacks amusement and recreation.Therefore, influenced the development of tandem bicycle and popularize.The utility model greatly reduces the difficulty of riding by improving the transmission device of bicycle, helps the popularization of tandem bicycle.
Three. content of the present utility model
The utility model overcomes the defective of prior art, and it is easier that tandem bicycle is ridden, provide a kind of ride instead of walk with amusement and recreation in one, the converter tools of riding instead of walk of riding safety.
The technical solution of the utility model: this double amusement and recreation bicycle, it contains front and back wheel, the front and back vehicle seat, the front and back handlebar, the front and back big trochal disc, back axis flywheel, the rear-wheel hub flywheel, support beam connects chain.On the axis of back composite driving mechanism is installed, in the both sides of rear-wheel hub two flywheels is installed respectively, two flywheels on the composite driving mechanism are connected with the flywheel of preceding big trochal disc with rear-wheel hub one side respectively by chain.
Composite driving mechanism contains the back axis, back axis housing, back big trochal disc, two flywheels, axle sleeve, packing ring and bearing, this back axis is in the axis housing of back, both connect with antifriction-bearing box at axis housing two ends, back and support, one side of back axis has been rigidly connected and has contained the back big trochal disc of pedal, opposite side has been installed an axle sleeve with two cover antifriction-bearing boxs, two flywheels have been installed on axle sleeve, two flywheels separate with packing ring and rotate with axle sleeve, one of them flywheel is connected with preceding big trochal disc by chain, another flywheel is connected with a flywheel on the rear-wheel hub by chain, at the axle head of this side another pedal that has been rigidly connected.
The rear-wheel hub both sides have been installed two flywheels respectively, and one of them flywheel is connected with the back big trochal disc by chain, and another flywheel is connected with a flywheel on the back axis by chain.The flywheel of back big trochal disc by chain and rear-wheel hub one side transmits back bicyclist's motion, and preceding big trochal disc transmits front bicyclist's motion by the flywheel of two flywheels on chain and the back axis and rear-wheel hub opposite side, and two motions are separate.
The beneficial effects of the utility model:
1. the utility model has reduced double difficulty of riding, because back axis design has composite driving mechanism, make former and later two people's driving separate, but two per capita the independent drive bicycle advance, making does not have the tandem bicycle people of the experience method of yet can very fast grasp riding of riding.
2. the utlity model has amusement and recreation, but the bicycle of independent drive per capita of seat advances before and after in the process of riding, another people can obtain having a rest when a people rode, and also can two people drive simultaneously, had increased amusement and recreation, and had been applicable to long-term travel.
3. the utility model is simple in structure, is easy to processing and manufacturing and applies.
Four. description of drawings:

The double recreation bicycle birds-eye view of Fig. 2
Axis composite driving mechanism structural representation behind Fig. 3
Five. the specific embodiment:
Embodiment: in conjunction with Fig. 1, Fig. 2, shown in Figure 3, the principle of work that is installed on the composite driving mechanism on the axis 13 of back among the figure is: back axis 13 is through back axis housing 10, two ends at back intermediate axle housing 10, be installed in the axis housing of back by deep groove ball bearing 12 and convex edge coro bearng 14, back axis housing is fixed by cycle frame.Select convex edge coro bearng 14, one for use, increase the rigidity that supports, the 2nd, be convenient to axial location.End at back axis 13 has been rigidly connected and has contained the back big trochal disc 3 of footstool, opposite side at the back axis has been installed an axle sleeve 15 with two cover antifriction-bearing boxs 11 and 16, on the external cylindrical surface of axle sleeve 15 with two flywheels 7 and 8 of being threaded, two flywheels are with its size and rotate with axle sleeve 15 at interval of packing ring 17 controls, at the axle head of this side another pedal that has been rigidly connected.During work, back big trochal disc 3, back axis 13, bearing 12,14 and pedal transmit back bicyclist's motion together by chain; Axle sleeve 15, flywheel 7,8, packing ring 17 and bearing 11,16 transmit front bicyclist's motion together by chain.Two motions are separate, mutually noninterfere.
When riding, before big trochal disc 1 by chain 2 with front bicyclist's Motion Transmission to the flywheel 8 that is installed on the axis 13 of back, flywheel 8 transmits motion to axle sleeve 15 by its in-to-in detent mechanism and is delivered on another flywheel 7 by bearing 11 and 16, flywheel 7 by chain 4 again Motion Transmission to a flywheel 9 that is installed on rear-wheel hub one side, this flywheel drives rear-wheel hub by detent mechanism travels forward bicycle.Back big trochal disc 3 transmits motion to by chain 5 on another flywheel 6 that is installed on the rear-wheel hub opposite side, and this flywheel drives rear-wheel hub by detent mechanism travels forward bicycle.Two people that ride can drive bicycle simultaneously, also can the independent drive bicycles, when a people drives or rides when very fast, because the effect of flywheel, another person's pedal can be along with transmissions together, thereby can obtain having a rest, two people can alternately ride, and are convenient.
