Because adopt said structure, the present invention's campus Tandem Bicycle compared with prior art has following beneficial effect:
1. resistance to abrasion is good, and is easy to maintenance:
The present invention changes bicycle linked transmission always into gear transmission, and transmission efficiency improves greatly, gear material, hardness is identical with motorcycle-gear, takes totally-enclosed transmission, and lubricating condition is good, do not press from both sides and sting clothing, pollution-free, thereby longer service life, through the evidence of riding of climbing repeatedly, load-carrying, many-side such as long-distance: product structure is reasonable, good looking appearance, resistance to abrasion is good, and is easy to maintenance, is subjected to customer's favorable comment deeply.
2. long service life:
Gear-driven service life, the change speed gear box of automobile and transmission shaft were used gear-driven exactly, reach the hundreds of thousands of kilometer its service life than several times of the long service life of chain gear, and the phenomenon of chain rupture bar just may appear in chain gear in use for some time.The axle of the present invention's campus Tandem Bicycle and gear train assembly can be accomplished normally to use need not repair in 10 years.
3. safety, good stability:
The invention belongs to the structural development of bicycle, is to share bicycle in transmission with axle and gear combination replacement chain and chain wheel set, not only laborsaving but also durable; Change the open type transmission of chain into the totally enclosed transmission, the working part of transmission can be steeped with oil immersion, and not only lubricating condition is good, and it can dailyly be protected as new and drive disk assembly, has avoided the erosion of wind and rain dust.The axle of the present invention's campus Tandem Bicycle closely cooperates into an integral body with each part of gear train assembly, the phenomenon that gets loose can not occur, and the whole drive system occupation space is little.
4. can make the campus vehicle again can body-building, amusement and recreation:
Because drive the campus Tandem Bicycle, need everybody of one mind, so it can cultivate student's team unity spirit, this product except the campus as the apparatus of student's the vehicle, collective's exercise usefulness or amusement with facility, also can promote on each Grand Duchy, travelling scenery district, residential quarter, villa garden, square, by guide controlling party in, introduce the sight spot to the visitor, the visitor listens explanation on one side, watch landscape on the way on one side, stepping on car more together, participating in environmental protection on one's own initiative, can also have an opportunity to take exercises.Therefore the present invention is the ideal selection of tourism and leisure, sightseeing amusement, taxi operation.
5. can carry many people:
The present invention is different with existing many person bicycles, tens even tens people simultaneously can sit around, by people's controlling party to and the brake, more because unique design, not only can the aspectant interchange of a plurality of friends can also make car itself more firm, abandon bicycle in the past turn fall down easily, can not face-to-face exchange between the friend, disadvantage that seating capacity is few.
6. in addition, also there is tangible advantage in the following areas in the present invention:
A. structure aspects: the campus bicycle group of pulling together is different with ordinary bicycle, and the gear train assembly that it is made according to the propeller-shaft principle with a cover has replaced the full of stains or spots chain of oil stain.The consumption of power seldom but also has following characteristics:
(1) ride brisk compare with chain bicycle laborsaving;
(2) durable: long service life is the several times of chain bicycle;
(3) in riding safe reliability greater than chain bicycle;
(4) nimble: because large components such as no large toothed disks, chain guard, the minimizing resistance that is in operation, ride convenient.
(5) clean hygiene, do not press from both sides sting, pollution clothes not, only annotate a lubricating oil every year and thoroughly eliminate the fraud of chain.
(6) simple in structure, it is convenient to repair, and compares with the chain derailleur easily to repair not perishablely, need not adopt driving parts such as sprocket wheel, chain, flywheel
B. function aspects: the campus Tandem Bicycle is integrated the Spinning of indoor body-building and the Karaoke of amusement and recreation, can be used as apparatus or the amusement facility of a kind of collective exercise usefulness.
Below, the technical characterictic to the present invention's campus Tandem Bicycle is further described in conjunction with the accompanying drawings and embodiments.
