Abstract
A tandem bicycle is composed of a saddle for the two persons at the front and rear parts of bicycle to ride, a handlebar for the front person to manipulate, a vehicle frame that is connected with the front and rear wheels, an independent foot pedal transmission device, wherein one end of the rear wheel axle is a positive thread and the other end is a reverse thread and the positive and reverse threads are respectively joggled with a unidirectional flywheel and the chain of the positive thread flywheel is connected to a fluted disk of the front foot pedal device; the chain of the reverse thread flywheel is connected to a fluted disk of the rear foot pedal device. The utility model is simple and reasonable in structure, rapid and convenient for assembling and operating, quite high in security. The driving is unaffected by other people, so two persons can simultaneously ride the bicycle together to drive the bicycle; or the front one or rear one singly rides the bicycle and at the same time the other person reversely rides the bicycle when one person rides the bicycle so as to form a racing, but not impacting the advancing speed and having the danger that the chain is shed off and thereby reaching the recreational and exercising effect.
Description
Technical field
The utility model relates to a kind of for the bicycle of pulling together of riding more than two people.
Background technology
Existing tandem bicycle kind is more, structure is different.Generally based on the former, the latter is auxilliary, rides synchronously with cingulum is moving.If the latter is motionless, then the former ride very painstaking.If the latter oppositely tramples with naughty phychology, at this moment, not only can not rotate even can produce and take off the chain phenomenon.No. 012452459, Chinese patent disclosed " tandem bicycle ", this car owner will comprise front and back wheel, parts such as W type vehicle frame, front fork, brake, front and back handlebar, seat, front and back, front and back are ridden, support, preceding axis, axis, rear axle, chain, chain wheel, flexibly connect rear bar on its W type vehicle frame, connect the overdrive clutch chain wheel on the beaming roller of preceding axis, axis, described overriding clutch chain wheel is connected on the speed-changing chain through bolt by flywheel and constitutes, the outer flexible connection eccentric bushing that puts of sprocket wheel.Its structure is complicated, is further improved.
Goal of the invention
The purpose of this utility model be to provide a kind of simple and reasonable, can a people or double or three people ride, easy and simple to handle, the safe and reliable bicycle of pulling together, to overcome weak point of the prior art.
By a kind of bicycle of pulling together of this purpose design-calculated, comprise seat cushion for front and back two people's saddle horses, the handgrip of the former operation, the vehicle frame that links front-wheel, trailing wheel, pedal driver independently is characterized in that rear axle one end is the forward screw thread separately, and the other end is a reverse thread, mesh one respectively and singly turn to flywheel, the fluted disc of foot pedal apparatus before the chain of forward screw thread flywheel is connected to; The chain of reverse thread flywheel is connected to the fluted disc of rear treadle device.
By this purpose design-calculated another kind bicycle of pulling together, the seat cushion that comprises three people's saddle horses before, during and after supplying, the former exercisable handgrip, the vehicle frame that links front-wheel, middle wheel, trailing wheel, pedal driver independently separately, an end of center-wheel arbor and rear center's wheel shaft is the forward screw thread before it is characterized in that, in addition in the middle of wheel shaft be reverse thread, mesh one respectively and singly turn to flywheel, the chain of forward screw thread flywheel is connected to the fluted disc of the foot pedal apparatus at the place ahead and rear respectively; The fluted disc of foot pedal apparatus in the middle of the chain of reverse thread flywheel is connected to.
The utility model is simple and reasonable; It is convenient rapidly to assemble; Easy and simple to handle, safety improves.Driving is not influenced by other people, can trample simultaneously when riding more than two people together to drive, and is perhaps trampled separately by the former or the latter, and a people tramples when another people of back oppositely tramples can present idle running, do not influence speed of advance, can not take off chain danger, to reach amusement and movement effects.
Description of drawings
Fig. 1 is the utility model one embodiment complete machine exploded perspective structural representation;
Fig. 2 is the package assembly scheme drawing of Fig. 1;
Fig. 3 is a back wheel drive mechanism scheme drawing among Fig. 1.
Fig. 4 is the running condition scheme drawing.
The specific embodiment
Be described further below in conjunction with drawings and Examples:
Referring to Fig. 1 one Fig. 4, originally the bicycle of pulling together, comprise seat cushion 10 for front and back two people's saddle horses, the former exercisable handgrip 11 links the vehicle frame 14 of front-wheel 12, trailing wheel 13, separately independently before pedal driver 15 and post legged foot device 16, one end of its rear axle 20 is provided with forward screw thread 21, the other end is a reverse thread 22, meshes one respectively and singly turns to flywheel 23, the fluted disc 151 of foot pedal apparatus 15 before the chain 24 of forward screw thread flywheel is connected to; The chain of reverse thread flywheel is connected to the fluted disc 161 of rear treadle device 16.Adopt this kind structure, because two singly turn to flywheel 23 fastening with forward, the reverse thread at rear axle 20 two ends, can be with marching forward.Step on another people of back as a people and then present idle running when oppositely trampling, can not resist mutually and take off the chain phenomenon.This vehicle frame can adopt welded frame or fast dismounting parts to form, and foot-operated and traditional is approximate.
According to technique scheme, the utility model can also be designed to three people and the above bicycle of pulling together of three people, the seat cushion that comprises three people's saddle horses before, during and after supplying, the former exercisable handgrip, the vehicle frame that links front-wheel, middle wheel, trailing wheel, pedal driver independently separately, one end of its preceding center-wheel arbor and rear center's wheel shaft is the forward screw thread, wheel shaft is a reverse thread in addition, mesh one respectively and singly turn to flywheel, the chain of forward screw thread flywheel is connected to the fluted disc of the foot pedal apparatus at the place ahead and rear respectively; The fluted disc of foot pedal apparatus in the middle of the chain of reverse thread flywheel is connected to.Driving system seat 1,3 bearings are the forward screw thread, and seat 2,4 bearings are reverse thread, by that analogy.
