Description
Technical field
The utility model relates to bike tech, particularly a kind of no chain-wheel bicycle.
Background technology
Existing big and small bicycle of all kinds all must have chain wheel driving mechanism.Chain wheel driving mechanism can improve vehicle wheel rotational speed, can make people's application force and car load gravity (gravity that contains the people) reach coordinated balance, meets the human engineering requirement.But the chain sprocket drive friction force is big, efficient is low, chain is fragile, falls chain and happens occasionally, and chain wheel driving mechanism often needs lubricated, lubricating oil usually can make dirty people's clothing or footgear.
Summary of the invention
The utility model designs a kind of no chain-wheel bicycle in order to overcome the above-mentioned defective of existing bicycle, use light, reliability is high.
The utility model is realized by following technical scheme.
Show as Fig. 1, be the structural representation of described no chain-wheel bicycle.The structure of the axle 2 of front vehicle wheel 1, front vehicle wheel 1, fork 4, connecting cylinder 6, handlebar 7 and assembly relation and existing bicycle are same or similar; Vehicle frame is connected and is formed by arched beam 8, oblique frame 9, vehicle seat bracing frame 14, connecting cylinder 6, and vehicle seat 10 is fixed on the top of bracing frame 14; The axle 18 of trailing wheel 17 is fixed on the tail end of oblique frame 9, and trailing wheel 17 is with the same or analogous wheel of existing cycle wheel or is motor that described motor is an external rotor electric machine, and when trailing wheel 17 was described motor, its stator axis was an axle 18; Described motor has electrical generator and motor function, can work as electrical generator, electrical motor exchange use, and current technology can produce described motor; Tailstock frame 11 front ends connect with vehicle seat bracing frame 14 tops, and tailstock frame 11 rear lowers connect with pole 16 supports that if look forward, pole 16 has two behind car, and the bottom of two poles 16 is separately fixed at two of axle 18; Controller 12, storage battery 13 are placed in the tailstock frame 11, and controller 12 has external power supply to insert charging inlet, and controller 12 is connected with storage battery 13 usefulness leads, and described motor is connected (not drawing among the figure) with controller 12 usefulness leads.
Show as Fig. 1 to Fig. 3, the diameter of middle wheel 5 is than the diameter of front vehicle wheel 1, the diameter of trailing wheel 17 is all big, middle wheel 5 constitutes like this: the tire 23 of middle wheel 5 is enclosed within the cylindrical of wheel hub 22, the mesopore of wheel hub 22 is solidly set on the cylindrical of ratchet 24, ratchet 25 usefulness bearing pins 26 are in relation to breach wheel 27, ratchet 25 can rotate around bearing pin 26, the lower end of extension spring 28 lies in the breach plane of breach wheel 27, the upper end of extension spring 28 lies in the bottom righthand side of ratchet 25, ratchet 25 and ratchet 24 relative when static its upper end be between two teeth of ratchet 24, and along in the wheel 5 forward rotation direction touch mutually with a flank of ratchet 24, show as Fig. 2, bearing fit is joined in the inside groove side of the left and right side of ratchet 25 and ratchet 24, and the cylindrical of breach wheel 27 and the interior circle of ratchet 24 are made into normal-running fit.
Show that as Fig. 2 tiltedly frame 9 connects with vehicle seat bracing frame 14 usefulness bolts 20, tiltedly the hole of frame 9 is concentric with the hole of vehicle seat bracing frame 14; The cylindrical of bearing 21 is made into flush fit with the hole of oblique frame 9; The middle wheel 5 that assembles is put between the sky of 14 of oblique frame 9 and vehicle seat bracing frames, axle 19 is passed from the endoporus of a hole of vehicle seat bracing frame 14, a bearing 21, the mesopore of breach wheel 27, the endoporus of another bearing 21, another hole of vehicle seat bracing frame 14 successively, axle 19 does not contact with the hole of vehicle seat bracing frame 14, axle 19 is made into flush fit with the endoporus of bearing 21, and the mesopore of axle 19 and breach wheel 27 is made into close-fitting and merges and use key connecting; At last left foot is pedaled 3, right pedal 15 reverse 180 ° of two ends that are installed in axle 19 respectively.
The together existing bicycle of described no chain-wheel bicycle braking mechanism, and connection brake brake also is connected (drawing among the figure) with the backguy of brake handgrip with the control dial of controller 12, when making brake, the described backguy control dial of pulling controller 12 earlier spurs the braking of brake brake again after to a certain degree.
Near handle position controlling organization (not drawing among the figure) is set at handlebar 7, controlling organization is connected with controller 12.
Suitable protective cover is set respectively covers on front vehicle wheel 1, middle wheel 5, the trailing wheel 17 (drawing among the figure).
An overriding clutch is formed in ratchet 24, ratchet 25, breach wheel 27, bearing pin 26, extension spring 28, its effect is the same with the flywheel (backgear) of existing bicycle, when the people pedal the pedal 3 that turns left, when right pedal 15 moves ahead car, take turns 5 in this overriding clutch combination, when the people stops to pedal commentaries on classics or back-pedalling commentaries on classics, middle wheel 5 slippages of this overriding clutch and rotation.
If trailing wheel 17 described motors, when car normally moves ahead, the people makes the stator coil open circuit of described motor by described controlling organization control controller 12, at this moment the outer rotor kiss the earth of described motor freely rotates and serves as rear wheel, perhaps make controller 12 give described motor from storage battery 13 power takings, at this moment making described motor is motor working condition, serves as drive wheels or power-assist wheel; When brake, brake is the control dial by described backguy pulling controller 12, and controller 12 makes described motor be the generating of electrical generator operating mode, and the electricity that sends is by 13 chargings of controller 12 accumulators.
Be noted that and ride described no chain-wheel bicycle, speed and existing bicycle difference are not many.Because the diameter of middle wheel 5 can be accomplished the twice of existing cycle wheel.Wheel diameter such as existing sixteen bicycles is 56 centimetres, and its hinge wheel has 48 teeth, and its minor sprocket has 20 teeth, and its sprocket ratio is exactly 1: 2.4, and promptly the people is pedaled a circle, and wheel changes 2.4 circles, will advance 422 centimetres of 56 π * 2.4 ≈ of car; If middle wheel 5 diameters of described no chain-wheel bicycle are made 112 centimetres, the people is pedaled 1 circle, will advance 352 centimetres of 112 π * 1 ≈ of car.
The effect that the utility model is useful:
1, described no chain-wheel bicycle does not have chain, the sprocket wheel that resembles existing bicycle, and not only friction force is little and laborsaving, efficient is high, and easy break-down not.
2, if described no chain-wheel bicycle is trailing wheel 17 usefulness and the same or analogous wheel of existing cycle wheel, then simple than existing bicycle structure, cost is low; Described no chain-wheel bicycle, if the described motor of trailing wheel 17, though than existing bicycle structure complexity, cost height, but described motor energy regenerative brake, the brake energy that reclaims is used for the power-assist driving, make the people more brisk by bike, and storage battery 13 capacity that ought dispose are enough big, then described no chain-wheel bicycle just becomes no sprocket wheel Electrical Bicycle.
Although 3 count described no chain-wheel bicycle slightly slower than existing bicycle, but described no chain-wheel bicycle is laborsaving, it is much smaller that the consumption force rate people that the people is pedaled 1.2 circles are pedaled the consumption power of existing bicycle 1 circle, and the people is pedaled described no chain-wheel bicycle 1.2 circles, to advance 422 centimetres of 112 π * 1.2 ≈ of car, this distance equates with the distance of pedaling existing bicycle 1 circle.So because described no chain-wheel bicycle is than existing bicycle labor saving, in fact the people rides described no chain-wheel bicycle ratio and rides that to have bicycle now brisk.
4, owing to above advantage, described no chain-wheel bicycle promotion prospect is good.
