Abstract
A kind of bicycle driven by slot-and-crank, it has particularly done improvement to driving device.This driving device is characterized in a pair of pedal lever also is installed on bicycle rack except that having common hinge wheel, chain, flywheel and crank, and with connecting rod connecting crank and pedal lever.This bicycle pedal force line is near hip joint, and when the power of pedaling was identical, the suffered pulling force of bicyclist's leg muscle was littler than Regular Bicycle, whenever pedaled pedal lever once, and the corner of crank can reach 180 °.The bicycle racing that adopts this transmission device to make can make athletes ' performance significantly improve.The present invention is simple in structure, makes, assembles easily, also can adorn whole chain cover, good looking appearance, and the riding safety performance is good.
Description
A kind of bicycle driven by slot-and-crank belongs to the improvement of bicycle drive.
Common bicycle drive is made up of pedal, crank, hinge wheel, chain, flywheel.Bicyclist's both feet are pedaled the pedal on a pair of reverse crank alternately, make crank make circular movement, through hinge wheel, chain, flywheel transmission, drive trailing wheel and rotate, and drive bicycle and advance.Adopt this driving device, when crank and ground when vertical, the transmission dead angle appears, the bicyclist is whenever pedaled once, the angle that hinge wheel turns over approximately is 130 °.So the acting of the bicycle of this transmission device is discontinuous, the effort of riding, speed is slower.In order to overcome above-mentioned shortcoming, many inventors have designed pedal-type bicycle and drive spindle driving bicycle.As the CN85203897u " pedal-type bicycle " that Patent Office of the People's Republic of China announces, be to replace crank with the pedal type lever, the bicyclist up and down reciprocatingly steps, and drives the chain transmission part with left and right sides flywheel, drives bicycle and advances.This structure makes the people more continuous to the bicycle acting, so it is comparatively fast more laborsaving to ride.But this structure is whenever pedaled and is once all wanted jack, and this wants consumed energy.When a certain batter was pedaled the arrival nadir, this batter was pedaled together with the original kinetic energy of people's leg and is consumed in vain, can not be converted into the kinetic energy that opposite side pedal type lever moves downward.Ride when very fast, the people is to the poor continuity of bicycle acting, this quite common bicycle is whenever pedaled once, 180 ° of the angle out of reachs that hinge wheel turns over, this bicycle rear is not adorned power-transfer clutch and just can not be fallen back in addition, also special interlinked mechanism, complex structure must be set between two pedal type levers.The CN87100276 A " actuating unit for bicycle " that announces of Patent Office of the People's Republic of China and for example, it unites two into one interlinked mechanism and hinge wheel, the crank of both sides pedal, thereby solved shortcoming above-mentioned, but pedal of this device is stepped near nadir, when also having a segment distance apart from nadir, the another pedal also and then moves downward.When the hinge wheel uniform rotation of this device, the linear velocity of pedal upward movement is unfavorable for riding greatly faster than the linear velocity that moves downward.Whenever pedal once, the friction force institute work that the people overcomes between slide block and the guide rod is also bigger.
Purpose of the present invention mainly is to improve at the existing shortcoming of above-mentioned bicycle drive, thereby provides a kind of simple and reasonable for structure, and it is more laborsaving faster to ride, and more meets human engineering, and safety performance is good, the bicycle of good looking appearance.
The design plan of realizing above-mentioned purpose is, at the cycle frame left and right sides one anchor shaft is installed respectively, one end running-fit of a pair of pedal lever is installed on the anchor shaft, and the other end is installed pedal, is connected between both sides crank and the pedal lever with the connecting rod running-fit then.
The bicycle drive of above-mentioned formation, its hinge wheel, chain, chain guard, flywheel, axis parts are identical with ordinary bicycle.Simple in structure, make, assemble easily, also can adorn whole chain cover, safety is attractive in appearance.This car is pedaled force line near hip joint, and when the power of pedaling was identical, the suffered pulling force of bicyclist's leg muscle was littler than Regular Bicycle.And do not need jack in riding, and whenever pedal pedal lever once, the corner of crank can reach 180 °, makes chain continuous substantially to the trailing wheel acting, thereby reaches laborsaving, the fast speed purpose of riding.
Accompanying drawing 1 is a transmission structures scheme drawing of the present invention.
Accompanying drawing 2 is an embodiments of the invention integral structure scheme drawing.
In the accompanying drawing: 1, crank 2, axis 3, hinge wheel 4, chain 5, chain guard 6, vehicle frame 7, flywheel 8, chain stay 9, bracing strut 10, anchor shaft 11, pedal lever 12, pitman shaft 13, connecting rod 14, pedal 15, following pipe
The invention will be further described below in conjunction with accompanying drawing.
The chain stay (8) that the former level of cycle frame (6) is installed is installed with certain gradient, and its gradient can promptly become 21～27 ° of angles with pipe (15) is identical down with horizon, and pedal lever bracing strut (9) is gone up in welding respectively on two chain stays (8); Then a pair of end that the pedal lever (11) of pedal (14) is housed is installed on the bracing strut (9) with anchor shaft (10), one end of anchor shaft (10) cooperates with bracing strut (9) with screw thread, and the other end cooperates with pedal lever (11) with ball bearing of main shaft; One end of left and right sides crank (1) is installed on two of axis (2), all be fixed with pitman shaft (12) on the other end and the pedal lever (11), connecting rod (13) just is connected in therebetween, and connecting rod (13) can be that antifriction-bearing box cooperates or bearing shell cooperates with cooperating of pitman shaft (12).In the time of should making pedal (14) the arrival nadir on the pedal lever (11) in addition in design and assembling, the connecting rod (13) on another pedal lever (11) is misaligned with crank (1), forms 0.5～6 ° angle.Like this when pedal (14) when vertex begins to be stepped on suddenly, hinge wheel (3) can not reverse, and makes chain (4) more continuous to the trailing wheel acting; This structure has increased the distance of pedal extreme higher position and extreme lower position simultaneously, further increases people's acting, so the bicycle racing that adopts this drive mechanism to make can make athletes ' performance significantly improve.
Claims (5)
