The bicycle saddle is connected with an integrated part of the elastic beam composed of a plate spring, thus effectively realizing cushioning and attenuating shakes due to bicycle vibration during riding.
Description
Technical field
The utility model relates to a kind of bicycle.
Background technology
The chain wheel driving mechanism of the most popular bicycle of people all is to be made of with flywheel and chain drum ingear driving chain flywheel, axis chain drum and a while of being loaded on the hind axle at present.Because the chain drum of captiveing joint with pedal drives wheel by chain direct drive flywheel, pedal drives the arm of force length of driving moment and the arm of force length of car resistance moment differs bigger, thereby require great effort by bike, it is all the more so by bike particularly to run into the weather of blowing.Therefore, mostly the elderly and children are the small-wheel bicycle of riding.And existing small-wheel bicycle only is that vehicle wheel directly reduces, body construction does not change, and the Saddel receiver beam column of saddle and vehicle frame still is a rigid attachment also, and saddle only depends on the saddle spring damping, can not cushion effectively and damping during the vehicle pitching vibrations, make the people feel very uncomfortable.For the elderly, also be unfavorable for safety by bike.
The utility model content
The purpose of this utility model provides a kind ofly rides briskly, laborsaving, can effectively cushion and the car body of decaying jolts vibrations to human body chatter, particularly is fit to the double-stranded secondary driving type damping bicycle that the elderly and children ride.
Double-stranded secondary driving type damping bicycle is by vehicle frame, be loaded on front forked frame, saddle on the vehicle frame, be loaded on front-wheel on the front forked frame, be loaded on the trailing wheel on the vehicle frame rear crotch and the chain drum of the bicycle that the transmission device that is made of the flywheel on the chain drum that has pedal, the hind axle, driving chain constitutes and flywheel between initiatively driving chain wheel and driven driving chain wheel are arranged, chain drum is connect by driving chain with the active driving chain wheel, and driven driving chain wheel connects by driving chain and flywheel.Chain drum, initiatively driving chain wheel, driving chain and driven driving chain wheel, flywheel, driving chain constitute the sprocket wheel mechanism of driving up.Driving and driven driving chain wheel whole wheel hub connects, and is loaded on the projecting shaft that is connected and fixed on the vehicle frame axle sleeve by ball bearing of main shaft.Integral body is connected with spring perch on the vehicle frame main beam, and an end of the elasticity Saddel receiver beam of being made by plate-shaped springs is connected and fixed on spring perch.One end has the whole Saddel receiver standpipe that connects the connecting panel that has the support beam hugging of the seatpillar locking strap other end and is connected and fixed at the other end of saddle elastically supported beam by connecting panel.
Be convenient to regulate and change the height of saddle when riding use, the saddle height regulating mechanism is arranged between saddle elastically supported beam and spring perch for vehicle.The saddle height regulating mechanism by saddle elastically supported beam connecting panel, have height adjustment card hugging DOCK LEVELER, the back plate of regulating jack is arranged and fasten, constitute the block catch gear with the tubulose locknut that blocks the band plate hand of fastening screw thread fit and constitute with whole its upper face upper edge car body axial distribution that is connected of vehicle frame main beam by card, saddle elastically supported beam connecting panel and spring perch are hinged, and the DOCK LEVELER and the saddle elastically supported beam connecting panel other end are hinged.The saddle elastically supported beam is connected and fixed on saddle elastically supported beam connecting panel.
For convenience the height adjustment of handlebar and vehicle are ridden lightlyer, and further improving of double-stranded secondary driving type damping bicycle is that the locknut of the stem tie down screw that connects with the swelling of front forked frame central siphon is the tubulose locknut of band plate hand.Stem has whole bonded assembly handlebar transverse tube strut bar, supports rod end integral body and is connected with handlebar transverse tube locking clip, and the handlebar transverse tube is that the fastener of the tubulose locknut of band plate hand is locked and is supporting rod end by locking clip and locknut.Driven driving chain wheel wheel footpath is greater than active driving chain wheel wheel footpath.
The double-stranded secondary driving type damping bicycle chain wheel driving mechanism that the utility model provides is double-stranded secondary transmission, thereby vehicle is ridden brisk, laborsaving.Saddle connects with the elastic beam that the integral structure part of vehicle body is made by plate-shaped springs, and the car body that can cushion effectively and decay when vehicle is ridden vibrations are to the chatter effect of human body.Handlebar, saddle height are regulated the tubulose locknut of the locknut of the fastener that uses of being locked as the band plate hand, its use, easy to operate, quick.Use that the small-wheel bicycle of making is particularly suitable for middle-aged and old and children ride.
