Abstract
The utility model relates to a speed regulator for bicycle centre shafts operated by pedaling positively and inversely, which is composed of the centre shaft, forward and reverse travelling ratchet wheel couples, a pinion, and a support disk. A chain wheel of the centre shaft rotates positively regardless of pedaling positively or inversely. So the bicycles can be caused to travel by pedaling positively or inversely. The rotation speed of a chain wheel of a centre shaft can be regulated by changing the teeth number of the two gear wheels. The speed regulator has the advantages of compact structure, high driving efficiency, and convenient installation. The speed of the original bicycles can be multiplied in series after the speed regulator is arranged. The tiredness can be alleviated by pedaling positively or inversely to change forced muscles of human legs. The riding power is increased. The climbing capacity is reinforced by pedaling inversely. The speed regulator can be used for civil bicycles, cross-country bicycles, racing bicycles, and children's bicycles, and can also be used for power bicycles in scientific researches.
Description
The utility model relates to a kind of positive and negative stepping bicycle axis transmission system.It is applicable to the manually driven bicycle, uses its positive and negative scrunching that bicycle is moved ahead, and is scrunching under the identical condition of rotating speed, and the speed of advance when speed of advance during forward pedaling and backward pedaling is different.The utility model also can be used on the manual tricycle.
The bicycle middle shaft speed-changing device that uses both at home and abroad all is a forward pedaling at present, can not drive bicycle and move ahead when backward pedaling.
The purpose of this utility model is to avoid weak point of the prior art and a kind of positive and negative bicycle middle shaft speed-changing device of being made up of axis, positive and negative capable ratchet even summation gear that all bicycle is moved ahead that scrunches is provided.The utility model compact conformation, the driving efficiency height, institute takes up space little, easy for installation.Step on bicycle and all move ahead owing to just pedaling back-pedalling, thus convertible riding posture, and make two kinds of rotating speeds that move ahead of axis sprocket wheel output under the identical condition of rotating speed scrunching.If this device is installed on the multi-speed bicycle, the attitude of then can not only conversion riding and the gait of march progression of bicycle is doubled (, can be changed into 12 speed) as being 6 speed originally.
The utility model is realized its purpose as follows: the utility model comprises axis 1, positive and negative capable ratchet idol 2, miniature gears 8, pinion shaft 9 and supporting disk 12; Positive and negative capable ratchet idol 2 is contained on the axis 1 of local overstriking with thread connecting mode, and miniature gears 8 supports between two outer rings of positive and negative capable ratchet idol 2 and by pinion shaft 9, and pinion shaft 9 is fixed on the supporting disk 12.Positive and negative capable ratchet idol 2 is made up of inner ring 4, outer ring 5, outer ring 6, just capable ratchet 3 and the ratchet 13 of instead going, inner ring 4 combines with outer ring 5 by just capable ratchet and forms a just capable ratchet, inner ring 4 combines with outer ring 6 by anti-row ratchet and forms an anti-row ratchet, in the endoporus of outer ring 5, be shaped on a circle and just going ratchet and become sprocket wheel 11 on the cylindrical sidewall, to be shaped on a circle internal tooth to form internally toothed annulus 10 being shaped on a circle form of gear tooth on the cylindrical, in the endoporus of outer ring 6, be shaped on the anti-row of circle ratchet and on cylindrical, be shaped on a circle external tooth and form external gear 7; 8 whiles of miniature gears and external gear 7 and internally toothed annulus 10 engagements realize the Motion Transmission between the outer rings 5 and 6, and miniature gears 8 adopts two, is symmetricly set between outer ring 5 and the outer ring 6.When forward pedaling, axis just changes, the forward ratchet in conjunction with, just change, the sprocket wheel of making one with the forward ratchet just changes, sprocket wheel moves ahead by the chain drive bicycle.When backward pedaling, the axis counter-rotating drives the external gear counter-rotating by anti-capable ratchet, through miniature gears inner gear is just changeed again, and sprocket wheel and inner gear are made one, and sprocket wheel also just changes like this, therefore, bicycle is moved ahead.The velocity variations of sprocket wheel can realize by the internally toothed annulus on the change outer ring 5 and the ratio of the external gear number of teeth on the outer ring 6.
The utility model compact conformation, the driving efficiency height, institute takes up space little, easy for installation; Aspect the cycling dynam, utilize positive back-pedalling to change bicyclist's body gesture, thereby the muscle group that conversion people leg is exerted oneself to alleviate human-body fatigue, increase the power of riding, this is the requirement that meets sport biomechanics; Because positive back-pedalling speed ratio difference can be utilized the drive torque of back-pedalling increase to trailing wheel, strengthens hill climbing ability; Improving the bicycle function aspects, the utility model can make bicycle speed progression double (being the single speed car originally, just becoming double speed after the utility model is installed, is that 6 speed can be changed into 12 speed originally); The utility model can be used for civilian vehicle, mountain bike, racing car and perambulator, in addition, also can be used for cycle ergometer in scientific research.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:
Fig. 1 represents constructional drawing of the present utility model.
Among Fig. 1: 1, axis 2, positive and negative capable ratchet idol 3, just capable ratchet 4, inner ring 5, outer ring 6, outer ring 7, external gear 8, miniature gears 9, pinion shaft 10, internally toothed annulus 11, sprocket wheel 12, supporting disk 13, anti-capable ratchet
Fig. 2 represents to install the bicycle scheme drawing behind the utility model.
Among Fig. 2: 11, sprocket wheel 12, supporting disk 14, tightening screw 15, tightening screw 16, press strip 17, chain 18, vehicle frame
When forward pedaling, axis 1 is just changeing, and inner ring 4 is just changeing, and combines and make it just to change by just capable ratchet 3 with outer ring 5, and the sprocket wheel 11 generations drive chain 17 on outer ring 5 is just capable, drives bicycle and moves ahead; Meanwhile the internally toothed annulus 10 on the outer ring 5 drives outer ring 6 and oppositely dallies through miniature gears 8, external gear 7.
When backward pedaling, axis 1 counter-rotating, inner ring 4 counter-rotatings, inner ring 4 combines and makes its counter-rotating (at this moment outer ring 5 combines with inner ring 4 disengagements) by anti-capable ratchet 13 and outer ring 6, external gear 7 on the outer ring 6 is just changeing miniature gears 8 with miniature gears 8 engagements, miniature gears 8 again with outer ring 5 on inner gear 10 engagement, outer ring 5 is just being changeed drive bicycle to move ahead, thereby realizes that back-pedalling moves ahead.
The revolution ratio of sprocket wheel 11 in the time of can adjusting positive back-pedalling by the ratio of number of teeth that changes internally toothed annulus 10 and external gear 7.
