Abstract

Telescopic stepping on that bicycle was used is turned, including fixed gear, flexible frame, the footboard, fixed gear fixes on the bicycle tripod, bicycle car axis is connected with flexible frame, be provided with a pair of location gear and a pair of driving gear and coaxial a pair of driven gear in the flexible frame, flexible rack and a pair of location gear and the meshing of a pair of driven gear of double -sided belt tooth, fixed gear is the moon tooth form gear of double -deck setting, two driving gears mesh with a fixed gear respectively, the driving gear rolls on fixed gear when stepping on the bicycle footboard, coaxial driven gear will rotate with the driving gear simultaneously, and driven gear drives flexible rack movable. The utility model discloses simple structure, manufacturing costs is cheap, is applicable to to be equipped with to step on the bicycle that turns, can reduce the moment of resistance for it is light when the bicycle is ridden, laborsaving.

Description

The Telescopic pedal crank of bicycle use
Technical field the utility model relates to bicycle part, specifically bicycle middle shaft Ta Guai mechanism.
Background technology
Stepping on that existing bicycle is connected with axis is turned, and the pedal of its right and left is equidistant from the distance of axis, is a kind of lever construction of equiarm in mechanics, thus during cycling as not having speed disk comparatively to require great effort.Although lengthening is stepped on the length turned and can be obtained larger torque, because radius of rotation becomes large, the arm or the leg that rotate swivel will exceed normal range, are therefore difficult to carry out stepping on the rotary motion of turning, simultaneously easy to be tired, produce uncomfortable.The bicycle that the pedal of bicycle connects is stepped on and is turned, and power only just can be applied in stepping between the predetermined rotational area in the unitary rotation interval of turning.When pedal moves from top to bottom, just torque can be obtained by stretcher.Now, put in power the interval that swivel makes it rotation, if step on the length turned, larger torque can be obtained; Be not applied in power interval (interval of idle running) in power, shorten if step on the length turned, then radius of rotation diminishes, and arm or leg would not exceed normal range, therefore easily transport.
Utility model content
The purpose of this utility model is to provide a kind of bicycle labor saving and steps on and turn, and can step on the arm of force turning two times of length by auto-extending within the stressed cycle than existing bicycle, steps on to turn the arm of force and can shorten to the arm of force also shorter than existing bicycle when non-stress.
For achieving the above object, the technical scheme that the utility model adopts is achieved in that the Telescopic pedal crank of bicycle use, comprise fixed gear wheel, flexible frame, pedal, fixed gear wheel is fixed on bicycle tripod, vehicle axis is connected with flexible frame, flexible frame is provided with a pair Positioning Gear and a pair driving gear and a pair coaxial driven gear, two-sided toothed flexible tooth bar engages with a pair Positioning Gear and a pair driven gear, fixed gear wheel is the double-deck selenodont gear arranged, two driving gears engage with a fixed gear wheel respectively, when stepping on bicycle pedal, driving gear rolls on fixed gear wheel, because driving gear and driven gear are coaxial, driven gear will rotate with driving gear simultaneously, driven gear just drives flexible tooth bar motion, flexible tooth bar is double-sided belt tooth, so will stretch out by tooth bar pipe on one side, tooth bar pipe is retracted on one side.Crank motion makes bicycle turn over like this.
Telescopic stepping on of the present utility model is turned, and its structure is very simple, and can miniaturization, lightweight, manufacturing expense is cheap, is applicable to be provided with the bicycle stepped on and turn, and can reduce resisting moment, light, laborsaving when making cycling.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model,
Fig. 2 is planar structure schematic diagram of the present utility model.
Detailed description of the invention illustrates embodiment of the present utility model below in conjunction with accompanying drawing 1: the Telescopic pedal crank of bicycle use, comprise fixed gear wheel 2, flexible frame 3, pedal 8, fixed gear wheel 2 is fixed on bicycle tripod, vehicle axis 1 is connected with flexible frame 3, flexible frame 3 is provided with a pair Positioning Gear 6 and a pair driving gear 4 and coaxial a pair driven gear 5, two-sided toothed flexible tooth bar 7 engages with a pair Positioning Gear 6 and a pair driven gear 5, fixed gear wheel 2 is the double-deck selenodont gear arranged, two driving gears 4 engage with a fixed gear wheel 2 respectively, when stepping on bicycle pedal 8, driving gear 4 rolls 2 on fixed gear wheel, because driving gear 4 and driven gear 5 are coaxial, driven gear 5 will rotate with driving gear 4 simultaneously, driven gear 5 just drives flexible tooth bar 7 to move, flexible tooth bar 7 is double-sided belt teeth, so will stretch out by tooth bar pipe on one side, tooth bar pipe is retracted on one side.Crank motion makes bicycle turn over like this.The utility model bicycle labor saving is stepped on and is turned and in all angular regions in stressed garden, can step on the arm of force turning two times of length by auto-extending than existing bicycle, when non-stress, this patent is stepped on and is turned the arm of force and can shorten to the arm of force also shorter than existing bicycle, so mix this patent bicycle labor saving to step on that turn can laborsaving one times (namely 100%).The strength that people is equivalent to existing bicycle two people is by bike by bike, and such people would not feel tired when bike riding.The utility model cost is low, effect is high, easily promotes.Ride and be furnished with the special bicycle labor saving of capital and interest and step on the bicycle turned and can feel relief much than existing bicycle, the distance of riding can be longer.Ride and more have enjoyment.
