Abstract

The utility model provides a building-body and riding two-purpose bicycle. The building-body and riding two-purpose bicycle is composed of parts of a bicycle frame, wheels, a driving device, a bicycle seat, and a bicycle handle. The building-body and riding two-purpose bicycle is characterized in that at least one of the wheels is installed on the bicycle frame by a shaft which is provided with an eccentric wheel, and an eccentric ring can be fixedly arranged on the periphery of the eccentric wheel in a detachable mode. When the eccentric ring has the maximum eccentricity relative to the shaft, the eccentricity of the eccentric ring is two times of the eccentricity of the eccentric wheel. The building-body and riding two-purpose bicycle not only can be used as a body-building and recreational bicycle, but also can be used as a common bicycle.

Description

The body-building dual-purpose bicycle of riding

The utility model provides a kind of bicycle, refers in particular to the bicycle that can change mutually between ordinary bicycle and body-building vehicle.

Existing have a jump, body-building recreation car to stop ﹠ go function generally is divided into two classes, one class is that wheel is oval-shaped, utilize the oval difference of radius everywhere and make the rider produce the sensation of jump, another kind is by using connecting rod mechanism to drive wheel, allow the relative position on the go of wheel and vehicle seat constantly change and make the rider produce the sensation of jump, because of the difference of the structure of these two types of cars and ordinary bicycle structure all bigger, can't change to ordinary bicycle, so can not resembling, they ride the ordinary bicycle, can only be as the entertainment body-building car.

For this reason, the purpose of this utility model is to overcome the deficiency of prior art, and provides a kind of not only can be used as to make that the people produces jump, the body-building recreation car of running to feel uses, and can be as the body-building that ordinary bicycle the uses dual-purpose bicycle of riding.

The technical scheme that realizes the utility model purpose is a kind of body-building dual-purpose bicycle of riding, comprise vehicle frame, be installed on the driving device on the vehicle frame, wheel, handlebar and vehicle seat, its special character be have at least in the wheel one be by axle mounting on vehicle frame, this middle part is an optical axis, two ends are provided with screw thread, dress eccentric wheel on the axle, the eccentric wheel inward at both ends has groove, the leading portion that is packed in the screw top closures at a two ends can stretch in the groove, be provided with a circle ball between groove walls and the screw top closures, ball separates eccentric wheel and screw top closures and axle, eccentric wheel outer periphery eccentric ring, the eccentric ring eccentric throw of the maximum of axle relatively is the twice of eccentric wheel eccentric throw, and eccentric ring is installed on the eccentric wheel removably, and an end of vehicle wheel spoke is installed on the outer ring of eccentric ring.

And eccentric ring is installed in eccentric periphery by bolt, but 3～8 of bolt rectangular distributions.

And eccentric eccentric throw can change in 1～25mm scope.

And when the axle of the trailing wheel in wheel is installed was provided with eccentric wheel, the flywheel in the driving device was installed on the wheel hub of eccentric wheel one side.

The crossbeam that technique scheme further is improved in the vehicle frame is divided into two sections, is provided with bumper between two sections.

And, the back vent of trailing wheel in the wheel and the support of supporting saddle are installed in the vehicle frame are fixed in one, front fork and hound that front-wheel is installed fix as one, and be connected through the hinge between back vent and the hound, and the two ends of crossbeam are distinguished also by hinge and pole, front fork hinged.

As shown from the above technical solution, the body-building that the utility model provides is ridden dual-purpose bicycle by vehicle frame, be installed on the driving device on the vehicle frame, wheel, handlebar and vehicle seat constitute, the difference of it and ordinary bicycle is to have at least one wheel to be installed on the axle on the vehicle frame eccentric wheel is housed, eccentric wheel outer periphery eccentric ring, the maximum eccentricity of the relative axle of eccentric ring is 2 times of eccentric wheel eccentric throw, eccentric ring is installed in the eccentric wheel periphery by bolt, generally 3～8 bolts can be set evenly, unclamp bolt and can adjust eccentric ring and eccentric relative position, the adjusting of eccentric throw when as a whole is done in realization to eccentric wheel and eccentric ring, when eccentric ring and eccentric wheel are eccentric as a global existence, the people just can produce jump because of accentric exists in the process by bike, the sensation of running, when adjusting eccentric ring and eccentric relative position, make both eccentric throw complementations, even both are zero as a single-piece eccentric throw, when not having off-centre, this car just can resemble rides the ordinary bicycle, this body-building is ridden motor moped to the change of ordinary bicycle structure and little as can be seen in sum, and it both can be used as the body-building recreation car, also can make ordinary bicycle and use.

Below with reference to accompanying drawing the utility model is described in further detail.
