Description

A kind of bicycle

Technical field:

The utility model relates to technical field of bicycles, is a kind of laborsaving damping bicycle specifically.

Background technology: bicycle is the simplest general current instrument, be applicable to the crowd at various ages of grown-ups and children, particularly for the such populous nation of China, not really prosperity and traffic are not under the good situation in economy, bicycle is the walking-replacing tool of people's first-selection especially, existing bicycle mainly contains following deficiency: consumption power is big, and the transformation of energy of riding instead of walk is little, and hill climbing ability is low, it is not laborsaving that variable speed bicycle is economized merit, speed is low, not damping of vehicle seat, poor performance.

Summary of the invention:

The purpose of this utility model is the deficiency that overcomes above-mentioned prior art, and a kind of laborsaving damping bicycle is provided, and has mainly solved problems such as existing bicycle consumption power is big, not damping of vehicle seat, poor performance.

In order to achieve the above object, the utility model is achieved in that a kind of bicycle, it comprises vehicle frame, handlebar, front and back wheel, front and rear brake, center shaft drives chain on the trailing wheel, vehicle seat, its special character is to establish bearing 3 on the trident shaft seat cover 18 of vehicle frame, establish outrigger cover 2 on the bearing 3, on outrigger cover 2, be provided with boss 19, remaining hole 20 corresponding connections on boss 19 and the fluted disc 1, being provided with remaining on fluted disc 1 is connected with gear 4, on trident shaft seat cover 18, establish and fixedly take position 10, establish three planetary wheels 6 on 10 fixedly taking position, three planetary wheels 6 are meshed with gear 4, dress bearing 5 is established axis rod 9 in trident shaft is sat cover 18 on planetary wheel 6, and bearing 7 is established at the two ends of axis rod 9 respectively, axis rod 9 is connected with toggle-action lever 22, quadrant gear 8 on the toggle-action lever 22 is meshed with three planetary wheels 6, and toggle-action lever 22 is connected with stretcher 11, at the 10 peripheral hardware jackets 21 of fixedly taking position.

In order further to realize above-mentioned purpose, its described vehicle seat is divided into inner sleeve 12, and inner sleeve 12 is divided into position-limited lever 15, and inner sleeve 12 and position-limited lever 15 insert in the remaining hole of the outer tube 13 that the bottom is provided with spring 14, the latch 16 of limiting in the bottom of position-limited lever 15; Inner sleeve 12 and outer tube 13 under the described vehicle seat are provided with concavo-convex notch; Boss 19 on the described outrigger cover 2 is three.

Compared with the prior art a kind of bicycle described in the utility model has following good effect: 1, owing to adopt the toggle-action lever of lengthening, according to lever principle, the quadrant gear of toggle-action lever one end drives planetary gear speed-changing, consumption power is little, can improve the work efficiency of bicycle, reduce the labour intensity of riding instead of walk; 2, speed is fast, and hill climbing ability is strong; 3, can prevent effectively that the cyclist from jolting, and gives comfort; 4, simple in structure, unique novel, handsome in appearance.

The specific embodiment:

In order to understand better and to implement, provide specific embodiment below in conjunction with accompanying drawing and describe a kind of bicycle of the utility model in detail.

Embodiment 1, referring to Fig. 1,2,3,4,5,6, adopt steel through the processing punching press, gear 4 is made in cutting, fluted disc 1, fixedly take position 10, trident shaft is sat cover 18, axis rod 9, the outrigger of earlier bearing 3 being packed into overlaps in 2, three boss 19 of processing on the outrigger cover 2, firm with remaining hole 20 on the fluted disc 1 anchor that connects, outer silk on the remaining platform on gear 4 endoporus silk mouths and the fluted disc 1 is tightened firmly, with the bearing 3 that assembles, the outer cover 2 of sitting, fluted disc 1, gear 4 is installed in trident shaft and sits on the cover 18, general fluted disc endoporus is sat the cover external diameter greater than trident shaft should rotate reliable bearing fixing for several millimeters; Offer three on 10 and sit holes fixedly taking position, and sit holes at three and load onto bearing 5 and three planetary wheels 6 respectively, the screw tightening that leaves in 10 lumen orifice of fixedly taking position is sat on the silk mouth of cover 18 at trident shaft, three planetary wheels 6 are meshed with gear 4; Axis rod 9 one ends are loaded onto bearing 7 again and inserted in the trident shaft seat cover 18, axis rod 9 other ends are also loaded onto bearing 7, and the external diameter of bearing 7 and trident shaft are sat cover 18 endoporus and fited very much; Toggle-action lever 22 is installed on the axis rod 9, quadrant gear 8 on the toggle-action lever 22 and three planetary wheel 6 engagements, toggle-action lever 22 is connected with stretcher 11, transparent outer cover cover 21 is installed fixedly taking position outside 10, adorn another stretcher 11 at axis rod 9 other ends again, thereby form the labour-saving pedal driving device; Said apparatus is installed on the trident support of cycle frame, is loading onto chain on handlebar, front and back wheel, front and rear brake, the center shaft driving trailing wheel on the vehicle frame by prior art again; Again with fixed installation position-limited lever 15 on the inner sleeve 12, insert then in the remaining hole of outer tube 13 of inner bottom part dress high pressure spring 14, on inner sleeve 12 and the outer tube 13 concavo-convex notch is arranged, load onto spacing latch 16 according to interior exterior notch correspondence then, leave certain up and down space between the damping internal and external casing, can move up and down, thereby form bicycle shock-absorbing sleeve pipe unit by spring, be fixed on the vehicle frame, car be installed on inner sleeve 12 sat.

A kind of bicycle described in the utility model is during use, owing to adopt the toggle-action lever of lengthening, the quadrant gear of toggle-action lever one end drives planetary wheel, gear passes to power and carries out speed change on the fluted disc, consumption power is little, can improve the work efficiency of bicycle, reduces the labour intensity of riding instead of walk; When bicycle moved in addition, when running into Uneven road, under the effect of the shock-absorbing sleeve pipe unit below vehicle seat, minimizing was jolted.
