Abstract
The utility model discloses an over-dead point driver of a bicycle. The utility model relates to the improvement of the structure of a driver of a bicycle. The aim of the utility model is to solve the problem of a dead point of a mechanism in the existing driver of the bicycle. A right driver 9 of the utility model is respectively connected with a five-way pipe 11 of the bicycle and the right end of a centre shaft 12, a left driver 10 is respectively connected with the five-way pipe 11 of the bicycle and the left end of the centre shaft 12, and two foot pedals 13 are respectively arranged on the right driver 9 and the left driver 10. When a pedal plate 13 at one side accords with the gravity direction, and a pedal plate 13 at the other side is arranged at the over-dead point position, the utility model realizes the drive of an over-dead point of the bicycle. When people ride the bicycle upwind or uphill, an effect of the utility model is obvious. The utility model not only saves labour, but also improves riding speed. The utility model is not only suitable for the bicycle, but also suitable for other man-power bicycles. The utility model has the advantage that the original structure of others components of the bicycle is not changed, and the dead point of the mechanism of the driver is eliminated.
Description
Technical field:
The utility model relates to a kind of improvement of bicycle driving device structure.
Background technology:
When the crank (being that connecting lever or title turn greatly) of bicycle is consistent with gravity direction (when two cranks are perpendicular to the ground), require great effort most during the step pedal.The so-called mechanism of mechanical engineering that Here it is dead point, this meets principle of dynamics.Bicycle is on the level land or descending when riding, common inertia by bicycle crank moves past the dead point naturally and overcomes it, but it is slow or when going up a slope when cycling speed, this problem is more outstanding, locate because the direction of the direction of power and the arm of force is consistent at the dead point, kinetic moment is zero, at this moment just feels special effort, and people by bike has to abandon riding and gets off implementation sometimes.At present, there is this problem in nearly all manpower bicycle.
The utility model content:
The purpose of this utility model is for solving mechanism's dead unit problem that existing bicycle driving device exists, provide a kind of bicycle to cross the dead point actuating device, the utlity model has the characteristics at mechanism dead point simple in structure, easy for installation, as can to eliminate actuating device.The utility model comprises bicycle bottom bracket 11, axis 12, two stretchers 13, the stage casing of axis 12 is arranged in the bicycle bottom bracket 11, it also comprises right actuating device 9 and left actuating device 10, right actuating device 9 is connected with the right-hand member of bicycle bottom bracket 11 with axis 12 respectively, left side actuating device 10 is connected with the left end of bicycle bottom bracket 11 with axis 12 respectively, and two stretchers 13 are separately positioned on right actuating device 9 and the left actuating device 10.The utility model is when a batter pedal 13 is in when consistent with gravity direction, and opposite side stretcher 13 had been in dead center position, has realized that bicycle crosses the dead point and drive.The utility model is used on the ordinary bicycle, against the wind or its effect of going up a slope when riding the most obvious, not only laborsaving, but also can improve riding speed; Which type of climatic conditions, which type of road conditions condition be used in the racing car of bicycle race, can improve games results, because all may exist during bicycle race.The utility model not merely is applicable to bicycle, and it also is applicable to other manpower bicycle.The utlity model has simple in structure, easy for installation, do not change the original structure of other parts of bicycle (manpower bicycle), eliminated the advantage at the mechanism dead point of actuating device.
Description of drawings:
Fig. 1 is a principle schematic of the present utility model, and Fig. 2 is an integral structure scheme drawing of the present utility model, Fig. 3 be the E of Fig. 2 to view, Fig. 4 is the structural representation of the specific embodiment four.
The specific embodiment:
The specific embodiment one: (referring to Fig. 1～Fig. 3) present embodiment is made up of bicycle bottom bracket 11, axis 12, stretcher 13, right actuating device 9 and left actuating device 10, the stage casing of axis 12 is arranged in the bicycle bottom bracket 11, right actuating device 9 is connected with the right-hand member of bicycle bottom bracket 11 with axis 12 respectively, left side actuating device 10 is connected with the left end of bicycle bottom bracket 11 with axis 12 respectively, and two stretchers 13 are separately positioned on right actuating device 9 and the left actuating device 10.
The specific embodiment two: (referring to the right actuating device 9 of the present embodiment of Fig. 1～Fig. 3) and left actuating device 10 respectively by transferring arm eccentric orbit 1, fixedly connecting lever 2, adjustable connecting lever 4, transfer arm ball pulley 5, axis fixed hub 6 is formed, captive joint with the outer end of bicycle bottom bracket 11 in the inner of axis fixed hub 6, axis fixed hub 6 is connected to one with transferring arm eccentric orbit 1, fixedly an end of connecting lever 2 is captiveed joint with the outer end of axis 12, fixedly the A of the other end of connecting lever 2 and adjustable connecting lever 4 end is hinged, stretcher 13 is hinged with the C end of adjustable connecting lever 4, transfer arm ball pulley 5 hinged, transfer arm ball pulley 5 to roll and be connected with accent arm eccentric orbit 1 with the B end of adjustable connecting lever 4.The fluted disc 14 of bicycle is captiveed joint with the fixedly connecting lever 2 of Rear gear wheel for bicycle (flywheel) side by connecting panel 15.Other composition is identical with the specific embodiment one with annexation.
The specific embodiment three: the fixedly connecting lever 2 of (referring to Fig. 3) present embodiment is a dome-shaped 20.Other composition is identical with the specific embodiment one with annexation.The fixedly connecting lever 2 of dome-shaped can will transfer arm eccentric orbit 1 to cover, and transfers on the arm eccentric orbit 1 to prevent that earth from entering and dropping on, and the rolling of arm ball pulley 5 is transferred in influence.
The specific embodiment four: the fixedly connecting lever 2 of (referring to Fig. 4) present embodiment is for long avette by 30.Other composition is identical with the specific embodiment one with annexation.Ovate-oblong fixedly connecting lever 2 simple structures, cost are low, can also intuitively transfer arm ball pulley 5 in the rolling of transferring on the arm eccentric orbit 1.
