Abstract
The utility model relates to a high efficiency pedal for bicycles, comprising eccentric shafts 23, 32 respectively fixed on both ends of the centre shaft of a bicycle frame, main cranks 1, 19 fixedly connected with eccentric wheels by circular rings 8, 28 and auxiliary cranks 4, 16, wherein, one end of each auxiliary crank is connected with the centre shaft 24, and the other end of each auxiliary crank 4, 16 is connected with the slide ways of the main cranks. Working dead angle is eliminated effectively by using the driving of the main cranks, the transmission of the auxiliary cranks and phase differences generated between the main cranks and the auxiliary cranks and between the main cranks by the eccentric wheels. The utility model not only accelerates the speed of ride, but also improves the climbing capacity of bicycles. The utility model has the advantage of labor-saving ride. The utility model is a pedal with a novel structure.
Description
The utility model relates to the efficient pedal of a kind of bicycle.
Bicycle pedal used for a long time, two pedals are individually fixed in vehicle frame axis two ends and 180 ° fixed sturcture each other, and the power (n) of pedaling of every pedal reaches maxim gradually by null value when riding, and get back to zero gradually from maxim again.Therefore then, the another pedal begins the same process that circulates again, has the acting dead angle in riding, a problem of the effort of riding, and especially last big when sloping, often has little time to exchange the strength of one's legs car and has just stopped, so the implementation of have to getting off.
Task of the present utility model is exactly the problem that exists at existing bicycle pedal, and a kind of nothing acting dead angle, good, the efficient pedal in the labour-saving of riding of acting continuity are provided.
Above-mentioned task is to realize like this.The efficient pedal of bicycle comprises the two cover eccentric wheel that are individually fixed in vehicle frame axis two ends, and two cover main cranks and two covers are paid crank.Eccentric wheel is contained on the axis axle shelves, and is fastening, with screw that itself and vehicle frame is fastening again with jam nut.The annulus fixing with the main crank welding is enclosed within on the eccentric wheel annulus and eccentric wheel free-running fit.Pay crank one end and be contained on the axis, lock with pin, the other end is connected with the chute of main crank by Transmission, and 180 ° each other on two pairs of cranks.Pedal main crank in riding and rotate around eccentric wheel, drive is paid a crank and is rotated around axis, drives the sprocket wheel rotation then, because eccentric effect, main, a pair crank rotation produces phase difference, pedals the no dead angle of acting, the labour-saving problem of riding thereby solved pedal.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is the structural representation of the efficient pedal of bicycle
Fig. 2 is the back view of Fig. 1
Fig. 3 is the A-A revolved sectional view of Fig. 1
Fig. 4 is main, pair crank motion time difference scheme drawing

Fig. 6 is pedaled the power functional arrangement for existing bicycle pedal
The efficient pedal of bicycle, comprise two cover eccentric wheel, the main crank that is individually fixed in vehicle frame axis two ends and pay crank, one end of main crank 1 is connected with stretcher 2, the other end and annulus 8 welding, and annulus 8 is enclosed within on the eccentric wheel 23, both are free-running fit, peg graft in shelves limit 22,36 and eccentric wheel two ends, assurance annulus 8 rotates around eccentric wheel, and eccentric wheel 23 is contained on the axis axle shelves 6, fastening with jam nut 7, use screw 10 and vehicle frame 9 fastening again.Pay crank 4 one ends and be loaded on the axis 24, lock with pin 5, Transmission 3 passes main crank 1 upper hopper chute 25 and is threaded with paying the crank other end, and Transmission 3 is a bearing fit with chute 25, and opposite side is owing to there is sprocket wheel.Annulus 28 can not be directly and main crank 19 welding, so weld tapped roundlet cover 12,21 and spout 14 in the outer of annulus 28, it is between two circle covers, annulus 28 is enclosed within on the eccentric wheel 32, both are free-running fit, peg graft in shelves limit 34,37 and eccentric wheel two ends, assurance annulus 28 rotates around eccentric wheel, and eccentric wheel 32 is contained on the axis axle shelves 35, fastening with jam nut 29, use screw 27 and vehicle frame 26 fastening again, sprocket wheel 13 is contained on the axis 24, and spout 14 is positioned at the sprocket wheel inboard.An end of paying crank 16 is contained on the axis 24, be positioned at sprocket wheel 13 outsides, lock with pin 33, sprocket wheel 13 can be same global facility with paying crank 16 also, Transmission 15 passes from the chute 17 of sprocket hole 20, sprocket wheel sideslip slotware 14, be threaded with the other end of paying crank 16, Transmission 15 and chute 17 bearing fits, one end of main crank 19 is connected with stretcher 18, the other end is a fork-shaped, and screw 30,31 passes hole on the fork-shaped and sprocket hole 11,20 respectively and is threaded with roundlet cover 12,21 on being welded on annulus 28.Pay the two ends that crank 4,16 lays respectively at axis 24,180 ° each other, promptly when assembling, making and paying crank 4,16 is on the opposite straight line of axle center, direction with the axis.
Pedaling when riding, because eccentric effect, in the half cycle of pedaling, main crank lags behind pays a crank and a sprocket wheel, and in the half cycle of receiving leg, main crank is ahead of pays a crank and a sprocket wheel on the contrary.In whole process, main crank is constantly changing with the relative angle of paying crank and sprocket wheel, and when a certain batter was pedaled no show nadir still, the opposite side pedal had entered the comparatively suitable position of pedaling.As shown in Figure 4, when pedal by t
0Walk to t
vThe time, pay crank angle α=180 °, the center of circle is O
1, main crank corner β＜180 °, the center of circle is O
2
When pedal by t
0Walk to t
eThe time, the main crank corner is β=180 °, pays crank angle α〉180 °, the phase difference of paying crank is α
1, the phase angle difference of main crank is β
1, and as can be seen from the figure β
1＜α
1, this only is the motion time difference map of a batter when pedaling half way around, opposite side pedal situation is also like this, illustrates that main crank and the phase difference of paying between crank, main crank and the main crank are to change with the variation of pedaling the position.As shown in Figure 5, t is the time, and n is main, pair crank moment, and α is for paying a crank angle, and β is the main crank corner, is t shown in Fig. 5 when the time is identical
Z=t
yThe time, α=a, β=c.When α=β=a, the time difference is t
2As α=a, during β=d, the time difference is t
1When main crank and main crank are alternately exerted oneself, n ≠ 0 but n〉0, β=b-e=d(is pedaled in this angle, people's leg can make energetically, this place is designed to d=145 °), and accompanying drawing 6 is functional arrangements that existing bicycle pedal is pedaled power, wherein t is the time, n is former crank moment, and α is former crank angle.
The efficient pedal of bicycle is skillfully constructed, and is reasonable in design, utilize main crank to drive, pay crank drive, that eccentric wheel makes is main, pay between the crank, produce phase difference between main crank and the main crank, eliminated the acting dead angle effectively, thereby the acting continuity is good, it is laborsaving to ride.
