Abstract

The utility model relates to a boosted bicycle which is composed of wheels 1, a handle bar 2, a back top beam 3, a back underbeam 4, a front beam 5 and a driving mechanism. The pedal drive mechanism is composed of a pedal 6, wherein, the middle of which is enchased at the left and the right sides of the bottom of the front beam, a front end is respectively enchased at both sides of the lower part of a front drive rod 7, and a front ratchet pawl 8 is fixed at the upper part of the front drive rod. A gravity drive mechanism is composed of a drive rod 12, a rod cover 13 and a back ratchet pawl 14, and the drive mechanism is composed of the ratchet wheel 18, a big and a small transmission wheels 19, 20, a big and a small gears 21, 22, a chain wheel 23, a chain belt 24 and a belt 25. Boosting can be simultaneously conducted by both feet of the utility model, and the gravitational energy can be converted to the driving force. The utility model has the advantages of high speed and labour-saving.

Description

Boosted bicycle

Boosted bicycle belongs to the improvement of rickshaw driver train.

The available man-power car all is to drive on stretcher by both feet are alternately afterburning by two legs.Its transmission device is gear and chain gear.This driver train easily makes bicyclist self wigwag motion, and its propulsive effort can not fully directly use.Especially bicyclist's self gravity does not utilize, and is wasted, and causes low, the slow-footed shortcoming long-term existence of rickshaw efficient.

The purpose of this utility model is the novel driver train of a kind of rickshaw of development, and this mechanism not only can rationally absorb the power of both legs, and can also absorb bicyclist's self gravity dexterously, it is transformed into promotes the power that car moves ahead.

The utility model is made up of wheel, handlebar, vehicle seat, back upper beam, back underbeam, front-axle beam, driver train.Driver train is made up of pedal drive mechanism, gravity drive mechanism, transmission device.Pedal drive mechanism is made up of stretcher, before driving bar, the preceding ratchet of a symmetry, the middle part of the stretcher of two symmetries is set in respectively on the left and right sides, front-axle beam bottom by axle, the front end of two stretchers is set in by axle on the both sides, bottom of before driving bar, and preceding ratchet is fixed on the top of before driving bar by axle.Gravity drive mechanism is made up of rear drive bar, bar cover, back ratchet, the upper end and the vehicle seat of rear drive bar are fixedly connected, the middle and lower part of rear drive bar is inserted in the bar cover, the upper end and the back rest of bar cover are connected and fixed, the lower end of bar cover is fixed on the rear end of front-axle beam bottom, and back ratchet is fixed on the bottom of rear drive bar by axle.Transmission device is made up of ratchet, large drive wheel, little power wheel, big gear wheel, miniature gears, sprocket wheel, chain, belt, ratchet is coaxial with large drive wheel, this is supported on by the axle sleeve frame on the bottom of front-axle beam, and little power wheel is coaxial with big gear wheel, and this axle is supported on the underbeam of back by the axle sleeve frame.Belt is connected on large drive wheel and the little power wheel, miniature gears and sprocket coaxiality, and this axle is supported on the upper beam of back by the axle sleeve frame.Big gear wheel and pinion, chain are set on the gear wheel of miniature gears and rear wheel.Preceding ratchet and ratchet are in the engagement of the front portion of ratchet, and back ratchet and ratchet are in the engagement of the rear portion of ratchet.

Both feet of the present utility model can be afterburning simultaneously, so do not have the wiggly problem of health, and bicyclist's self gravitation also can change propulsive effort into, so the more existing rickshaw of the speed of this car can double, but also can be laborsaving 50%, be a great revolution of rickshaw driver train.

Fig. 1 is the utility model integral structure scheme drawing.

Example: present embodiment is made up of wheel 1, handlebar 2, back upper beam 3, back underbeam 4, front-axle beam 5, driver train.Driver train is made up of pedal drive mechanism, gravity drive mechanism, transmission device.Pedal drive mechanism is made up of stretcher 6, before driving bar 7, the preceding ratchet 8 of a symmetry.The middle part of the stretcher 6 of two symmetries is set in respectively on the left and right sides, front-axle beam 5 bottom by axle 9, and the front end of two stretchers 6 is set in by axle 10 on the both sides, bottom of before driving bar 7, and preceding ratchet 8 is fixed on the top of before driving bar 7 by axle 11.Gravity drive mechanism is made up of rear drive bar 12, bar cover 13, back ratchet 14.The bottom of the upper end of rear drive bar 12 and vehicle seat 34 is fixedly connected, the middle and lower part of rear drive bar 12 is inserted in the bar cover 13, and can overlap in 13 at bar and move up and down, the bottoms in the bar cover 13 are provided with a coil spring 15 that heads on rear drive bar 12 lower ends, to alleviate the vibration to the bicyclist.The upper end of bar cover 13 is connected and fixed by hoop 16 and back upper beam 3, and the lower end of bar cover 13 is fixed on the rear end of front-axle beam 5 bottoms, and back ratchet 14 is fixed on the bottom of rear drive bar 12 by axle 17.Transmission device is made up of ratchet 18, large drive wheel 19, brief biography driving wheel 20, big gear wheel 21, miniature gears 22, sprocket wheel 23, chain 24, belt 25.Ratchet 18 is coaxial with large drive wheel 19, and this 26 is supported on the bottom of front-axle beam 5 by axle sleeve frame 27, and brief biography driving wheel 20 is coaxial with big gear wheel 21, and this axle 28 is supported on the underbeam 4 of back by axle sleeve frame 29.Belt 25 is connected on large drive wheel 19 and the brief biography driving wheel 20, and miniature gears 22 is coaxial with sprocket wheel 23, and this axle 30 is supported on the back upper beam 3 by axle sleeve frame 31.Chain 24 is set on the gear wheel 32 of miniature gears 22 and rear wheel.Big gear wheel 21 meshes in the front portion of ratchet with ratchet 18 with miniature gears 22 engagements, preceding ratchet 8, and back ratchet 14 meshes at the ratchet rear portion with ratchet 18.For preventing that ratchet 18 from bumping trousers, on ratchet 18, be covered with a ratchet casing 35, ratchet casing 35 is provided with opening at preceding ratchet 8 and ratchet 14 places, back.The storage power that also is provided with in ratchet 18 spring 33 that spirals, an end of the spring 33 that spirals are fixed on the axle 26, and the other end is fixed on the ratchet 18.
