Abstract
The utility model discloses a bicycle with a chain wheel type booster, which comprises a bicycle, a transmission chain and a chain wheel type booster. The chain wheel type booster comprises a box body, an output shaft and an input shaft, the output shaft is provided with an output shaft small chain wheel I, an output shaft large chain wheel, an output shaft small chain wheel II and an output shaft crankset, and the input shaft is provided with an input shaft large chain wheel, a double-linkage middle chain wheel and a clutch. Each chain wheel is driven correspondingly through the chain, the output shaft crankset is connected with a flywheel of the rear wheel of the bicycle through the transmission chain, and two ends of the input shaft are connected with a pedal expansion joint through an input end flywheel. A limiting bracket is movably arranged on the box body through supporting points, and the pedal expansion joint is arranged above the limiting bracket. The bicycle with the chain wheel type booster has the advantages of being compact and reasonable in structure, light and safe to ride, convenient and appropriate to fold and the like.
Description
Technical field
The utility model relates to a kind of bicycle, and is especially relevant with sprocket-type servo-unit bicycle.
Background technology
Existing sprocket-type morpet, its sprocket-type servo-unit is owing to adopt three shaft drive, the output shaft chain wheel is located at outside the casing, pedal stroke is spacing by carriage spring, rotatable quick detach joint of no handlebar and lighting, and it is big to exist size, complex structure, poor reliability, folding inconvenient, the low deficiency that waits of safety.
Summary of the invention
The purpose of this utility model provide a kind of compact conformation rationally, the sprocket-type servo-unit bicycle that puts in place of the light and handy safety of riding, folding convenient.
For achieving the above object, the utility model is achieved through the following technical solutions.Sprocket-type servo-unit bicycle, comprise bicycle, driving chain and sprocket-type servo-unit, the sprocket-type servo-unit comprises casing, output shaft and input shaft, output shaft minor sprocket I is housed on output shaft, the output shaft hinge wheel, output shaft minor sprocket II and output shaft chain wheel, the input shaft hinge wheel is housed on input shaft, duplex intermediate chain wheel and power-transfer clutch, output shaft minor sprocket I, the output shaft hinge wheel, output shaft minor sprocket II passes through the corresponding transmission of chain with input shaft hinge wheel and duplex intermediate chain wheel, the output shaft chain wheel is connected with the bicycle rear flywheel by driving chain, output shaft and input shaft by bearing installation on casing, the two ends of input shaft are connected with the step slip joint by the input end flywheel, the step slip joint is connected with step by movable curved joint, power-transfer clutch is connected with the fork handle, by the fulcrum activity spacing bracket is housed on casing, the step slip joint is positioned at the spacing bracket top.
Described sprocket-type servo-unit bicycle is provided with vehicle frame folding quick detach joint on the bicycle crosspiece, be provided with the rotatable quick detach joint of handlebar at the steering shaft middle part of bicycle, and top is provided with handlebar quick detach joint.
Described sprocket-type servo-unit bicycle is equipped with charged source car light on handlebar, be provided with spot lamp at the casing rear, is provided with handrail in the casing front portion.
The utility model compared with prior art has the following advantages: (one) is because the output shaft chain wheel is located in the casing compact conformation; (2) be that the cancellation tween drive shaft has dwindled casing owing to change former three shaft drive into two shaft drive; (3) be owing to be provided with spacing bracket, cancelled carriage spring, structure is more rationally reliable; (4) be because bicycle has assembled charged source car light and spot lamp, be convenient to night safe and ride; (5) be owing to be provided with rotatable quick detach joint of handlebar and handlebar quick detach joint, make folding convenient putting in place.
