Abstract
The utility model relates to a high speed bicycle which is provided with a front and a back wheels, a frame, a handle bar, a saddle and pedals. The utility model is provided with a double-chain secondary chain wheel speed increasing mechanism; a big chain wheel at the middle is connected with a small chain wheel fixed to a shaft sleeve at the back of the bicycle by a chain. The bicycle has high speed change radio, and thus, the utility model has a high speed; simultaneously, pedaling frequency and power are suitable for a human body; bicyclists feel comfortable and light, which is not easy to fatigue and is especially suitable for flat areas, villages or cities in riding.
Description
The utility model relates to the bicycle technical field.
Bicycle transmission device in the past all adopts the one-level speedup, because of being subjected to the restriction in foot-operated space, converter speed ratio is all not too high, even mountain region variable speed bicycle, maximum speed is still unsatisfactory, especially during fast running, need tightly pedal foot-operated, this usually makes people's breathe heavily, especially is unfavorable for cardiac's health.In addition, sprocket wheel aligning property was poor before and after the mountain region variable speed bicycle also existed, resistance is big, mechanical efficiency is low, effort, complex structure, fragile, drawback that the life-span is short.
The purpose of this utility model provides a kind of high-speed bicycle, and it is the speed height not only, and foot-operated frequency and strength are more suitable to human body, and during dispatch driving, the cyclist also feels comfortably cool, brisk, indefatigability.
The purpose of this utility model is achieved in that a kind of bicycle, comprise front and back wheel, vehicle frame, handlebar, vehicle seat, axis and foot-operated, it is characterized in that being provided with secondary sprocket wheel speed increasing mechanism, foot-operated hinge wheel links to each other with little gear wheel in the middle of by chain, middle little gear wheel and sprocket wheel broad in the middle fix by axle sleeve or axle, and are contained on the vehicle frame, are provided with the normal-running fit structure therebetween, sprocket wheel broad in the middle links to each other by the minor sprocket that chain and back axle put, and this minor sprocket is fixed on back axle and puts.
The little gear wheel in above-mentioned centre is a minor sprocket that is provided with ratchet structure, and foot-operated hinge wheel, pedal crank all are fixed on the axis.
The little gear wheel in above-mentioned centre also can be a minor sprocket, and fixedly an axle sleeve is established in the axis of pedal crank outside, and foot-operated hinge wheel is fixed on this axle sleeve, the outer tube normal-running fit on this axle sleeve and the vehicle frame, and this axle sleeve and middle between centers are provided with ratchet structure.
But the vehicle frame top below the above-mentioned intermediate chain wheel shaft entrucking seat also can be contained on the vehicle frame on the tie-beam between axis and back axle, and the intermediate chain wheel shaft can be beam type, stressed even for making, reliable in structure, preferably tie-beam is provided with " " type structure, and the intermediate chain wheel shaft is the twin beams fixed type.
Little gear wheel in above-mentioned centre and sprocket wheel broad in the middle preferably are fixed on the axle sleeve, and axle sleeve cooperates by bearing and axle, and axle is fixed on the vehicle frame.Or adopt other similar or equivalent structures to replace.
Steady for car body when the fast running, can on trailing wheel and/or front-wheel support, be provided with the spring shockproof structure.
Travel for ease of double, the people of back also can be afterburning, sprocket wheel broad in the middle and axle thereof are positioned in the middle of two wheels of front and back, sprocket wheel broad in the middle and middle little gear wheel are fixed on the hollow shaft, the axle of this hollow shaft and fixing two pedal cranks matches, be provided with ratchet structure therebetween, the axle of fixing two pedal cranks and the bearing bearing fit on the tie-beam of both sides, vehicle seat is whole strip shape or is divided into two vehicle seats.Be convenient to firmly for the people who makes the back, safety traffic can be provided with handrail on the vehicle seat both sides, and handrail is fixed on vehicle seat or the vehicle frame.
Because between the utility model back axle cover and minor sprocket be fixed sturcture, thus start and make intermediate chain wheel rotating element or foot-operated hinge wheel rotating element have certain inertia when travelling, steady when travelling, laborsaving.Because adopt two stage speed change, so converter speed ratio improves greatly, the speed of a motor vehicle is very fast, and frequency is slower, and is approaching with human body eupnea frequency, make that the cyclist feels relief, comfortable, laborsaving, indefatigability, have legs, can travel at a distance.Because adopt the single speed structure, so the bidirection chain wheel disc is good to positivity, the chain subtended angle on the minor sprocket is little, so than derailleur and one-level variable speed bicycle mechanism efficiency height, laborsaving.Simultaneously, the utility model also has the characteristics of compact conformation, terse, appearance looks elegant.Be equipped with sensitive brake, the safety in the time of can guaranteeing by bike and nimble.Especially suitable region of no relief, rural area or city are ridden and are sailed.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing, but not as to qualification of the present utility model.
Fig. 1 is the structural representation of embodiment 1.
Fig. 2 is the structural representation of embodiment 2.
Fig. 3 is embodiment 3 two people structural representations by bike.
Among Fig. 1, two pedal cranks 1 all are contained on the axis 3 with foot-operated hinge wheel 2, foot-operated hinge wheel 2 links to each other by the minor sprocket 5 (can claim little gear wheel or flywheel) of chain 4 with middle band ratchet structure, minor sprocket 5 is fixed by an axle sleeve with sprocket wheel 6 broad in the middle, axle sleeve is by bearing and intermediate chain wheel shaft 7 bearing fits, intermediate chain wheel shaft 7 is fastened on " " type tie-beam 8 by the both sides nut, be the twin beams fixed type, sprocket wheel 6 broad in the middle by another chain 9 be fixed on the minor sprocket 10 that back axle puts and link to each other, 11,12 is spring shock absorption mechanism.The speed of a motor vehicle can reach 40-50 kilometer/hour, leicht fallen D/A, and speed is high again, need not use oil again, and is pollution-free, so can replace the low speed motor bike to use.
Among Fig. 1, replace riding, can be used as power bicycle and use, need not establish drop-gear box in addition with lightweight engine.
Among Fig. 2, the intermediate chain wheel shaft is fixed on the top of car below-seat vehicle frame.
Fig. 3, being fixed with between the axle 13 of pedal crank and hollow shaft has ratchet structure, and hollow shaft is fixed together middle the minor sprocket of sprocket wheel broad in the middle and band ratchet structure, and match with bearing on " " font tie-beam 8 in spool 13 two ends.14 is strip shape two people's vehicle seats, and 15 for being fixed on 2 handrails on vehicle seat both sides.
