Abstract
The utility model provides an adjustable high speed bicycle drive device, which is mainly characterized in that a small triangle support frame is additionally arranged at the front end of the lower part of a triangle frame; a drive shaft is arranged on the small triangle support frame, and both ends of the drive shaft are respectively provided with a small tooth wheel and a multi-stage chain wheel; a big and a small tooth wheels in two stages are arranged on a rear wheel shaft; the small tooth wheel and a tooth disk with pedals, and the big tooth wheel and a small tooth wheel on the drive shaft at the front end are respectively connected in a drive way through a main and an auxiliary chains; the multi-stage chain wheel and a multi-stage chain wheel flywheel on the rear wheel shaft are connected by a driving chain, and the tooth disk at the position of the driving chain can be adjusted. The utility model has the advantages of simple structure, small resistance and abrasion, high transmission efficiency, high reliability, labor saving in riding, and board speed-adjusting ranges.
Description
The utility model relates to a kind of endless chain driving device by rider driving wheeled car, the adjustable adjustable high-speed bicycle driving device of especially a kind of transmitting ratio.
Existing various variable speed bicycle all is to adopt a ring chain and two chain wheels with multistage fluted disc to constitute the speed governing transmission device basically, and the transmission device speed adjustable range of this structure is limited, also requires great effort during rider.A kind of " bicycle height dual drive " disclosed among the Chinese patent CN2163788Y, its architectural feature is to set up the gear cluster transmission device on the basis of existing bicycle, promptly the top between chain wheel and flywheel is provided with the variable-speed drive of big miniature gears of multi-group and chain, by the engagement between gear and chain and gear meshing transferring power and increase, deceleration/decel.Such transmission structures complexity adopts multiple sets of teeth wheel speed change frictional resistance big, and it is terrible wear and tear, thereby transmission efficiency and reliability reduce, and it has only two kinds of selections of high, low speed, and speed adjustable range is narrower, and many velocity modulations that can not adapt to the modern means of communication save requirement.
The purpose of this utility model will overcome above-mentioned weak point of the prior art exactly, proposes a kind of simple in structurely, and the adjustable high-speed bicycle driving device of laborsaving and speed-regulating range width is ridden in wearing and tearing and resistance is little, transmission efficiency and reliability are higher.
The purpose of this utility model can reach by the enforcement of following technical proposal: the front end in existing ordinary bicycle spider bottom is set up little A-frame, settles two ends that the transmission shaft of little gear wheel of single-stage and multistage chain wheel power wheel is housed respectively on it.With the big or small two-stage gear wheel of installing on the hind axle that is contained on the axis band step chain wheel the same side, its little gear wheel is connected with being with the step chain wheel by the main chain bar, and is connected by secondary chain between the little gear wheel of single-stage on its big gear wheel and the front end transmission shaft.The multistage chain wheel power wheel of opposite side by chain drive-belt and hind axle on multistage chain wheel flywheel couple together, constitute the multi-change speed transmission device thus.For obtaining better result of use, the utility model also can adopt following technical measures: described multistage chain wheel power wheel and multistage chain wheel flywheel all adopt three grades of turriform chain wheel structures: multistage chain wheel flywheel bottom installing suspension type tensioning gear wheel on hind axle, so that after chain drive-belt speed governing gearshift,, and have the minimizing drag effect with its tensioning.
Accompanying drawing 1 is the structural representation of the utility model embodiment.
Accompanying drawing 2 is the birds-eye view of the utility model embodiment.
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail.Front end in conventional bicycle tripod 1 bottom is set up little A-frame 2, the transmission shaft 3 of settling tape spool to hold on it, and the two ends of transmission shaft 3 are separately installed with 4 and three grades of turriform chain wheel power wheels 5 of single-stage denticle wheel.The left end of spider 1 bottom axis 6 is fixed with band step single-stage chain wheel 7, and the left end of hind axle 8 is equipped with the big or small two-stage gear wheel 9 that tape spool holds, between its little gear wheel and the single x chain wheel of band step and its big gear wheel be connected transferring power by annular main chain bar 10 with secondary chain 11 respectively between the single-stage denticle on the front end transmission shaft 3 takes turns 4.Be connected at three grades of turriform chain wheel power wheels 5 on right side three grades of turriform chain wheel flywheels 13 by homonymy on chain drive-belt 12 and the hind axle 8, and, at the right-hand member of hind axle 8 the tensioning gear wheel 14 that matches with chain drive-belt 12 is installed with hang simultaneously by selector gear controlling and driving chain 12 residing chain wheel positions.When using the utility model device, act on the two-stage gear wheel 9 that the power on the band step chain wheel 7 passes on the hind axle 8 through main chain bar 10, take turns 4 through the single-stage denticle that secondary chain 11 passes on the front end transmission shaft 3 again by its big gear wheel, and produce the speedup effect at this.Select chain drive-belt 12 residing chain wheel position on three grades of turriform chain wheel power wheels 5 and three grades of turriform chain wheel flywheels 13 by the selector gear on the handgrip, the transmitting ratio of regulating therebetween can further be delivered to the power that is delivered on the single-stage denticle wheel 4 on the trailing wheel, and finishes the task of required high speed or driven at low speed bicycle running.
The utility model compared with prior art, it is simpler to have structure, wearing and tearing and resistance little, Transmission efficiency and reliability are higher, ride the characteristics such as laborsaving and speed-regulating range width, are fit to change Advance existing transmission mechanism of bicycle.
