Abstract
The utility model relates to a drive mechanism, particularly a backward concentric same speed swing mechanism which is used for a drive system of a bicycle. The utility model aims at the deficiencies which exist in a double circuit pedal drive mechanism on the existing drive system of the bicycle, such as uncomfortableness and inharmony in cycling, and the fatigue is brought on easily in cycling. The utility model provides the backward concentric same speed swing mechanism on the drive system of the bicycle which has reasonable structure, comfort and harmony in cycling, and the fatigue is not brought on easily in cycling. The utility model comprises a left shaft roller, a left conical tooth, a right shaft roller, a right conical tooth, a shaft coupling conical tooth and a plurality of bearings, wherein the left conical tooth is arranged on the left shaft roller; the right conical tooth is arranged on the right shaft roller; the shaft coupling conical tooth is meshed with the left conical tooth and the right conical tooth. According to need, two different structures with chains or no chain can be worked out by the utility model.
Description
Technical field
The utility model relates to a kind of transmission device, particularly a kind of reverse concentric same speed rotary mechanism that is used on the bicycle drivetrain.
Background technology
Pedal transmission mechanism on traditional bicycle is to adopt the single loop pedal transmission mechanism, during use, the mode of motion of sprocket wheel rotation before single loop pedal transmission mechanism on the bicycle has only mono-to lean on both feet alternately firmly to drive, structurally it exists a motion dead angle, when bicycle goes up a slope or quicken, make the cyclist feel hard; In addition, on traditional bicycle owing to adopted the single loop pedal transmission mechanism, directly saddle horse is capable for bicycle, and the position of bike saddle must be adorned high, otherwise people's shank can't be exerted oneself because of being in case of bending, and behind the position of the bike saddle dress height, people's bipod does not reach ground, the people by bike the time safety relatively poor.At the existing defective of single loop pedal transmission mechanism on traditional bicycle, people have designed a kind of double loop pedal transmission mechanism that is used on the bicycle drivetrain, the bicycle that this double loop pedal transmission mechanism is housed is light, laborsaving when going up a slope or quicken, and its bike saddle position can be reduced, people's bipod can contact on the ground, and is safer when making by bike.But car is advanced because the left and right sides beaming roller of double loop pedal transmission mechanism oppositely steps about adopting two direct geared external toothings to realize, so left beaming roller and right beaming roller can not be concentric, make it one in front and one in back, or one on the other, form an error angle, according to mechanics viewpoint, the dislocation time, long causing easily all exerted an influence fatigue to human body harmony, traveling comfort.
Summary of the invention
Task of the present utility model is at the in use existing above-mentioned fatigue that causes easily by bike time of the double loop pedal transmission mechanism on the existing bicycle drivetrain, uncomfortable in the time of by bike, inharmonic weak point, provide a kind of people of making by bike the time, to be not easy to cause fatigue, and more comfortable when making by bike, more coordinate the reverse concentric same speed rotary mechanism on the bicycle drivetrain of more reasonable structure.
The technical solution adopted in the utility model is finished in the following way: the reverse concentric same speed rotary mechanism on the bicycle drivetrain comprises left beaming roller, left bearing, left tapered tooth, two locating dowel pins, little bearing, right beaming roller, right tapered tooth, right bearing, connecting shaft awl tooth and two centre bearers.Wherein, left bearing is contained in the left beaming roller left side, the tapered tooth in a left side is contained in the left bearing right side, and be connected as a single entity by locating dowel pin and left beaming roller and be fixed on the shell, left side beaming roller left end can be adorned foot-operated handle, right-hand member has a pothole that little bearing is housed, little bearing bore connects together with the left end convex of right beaming roller, right tapered tooth and right bearing are contained in the left side of right beaming roller respectively, right two sides, the flank of tooth of right tapered tooth be towards a left side, and by locating dowel pin itself and right beaming roller are connected as a single entity, right bearing is fixed on the shell, connecting shaft awl tooth respectively with the tapered tooth in a left side, right tapered tooth is meshed, and two centre bearers are contained on the connecting shaft awl tooth side by side, and two centre bearers are separately fixed on the shell.The tapered tooth in a left side is identical with the number of teeth of right tapered tooth, thereby realizes oppositely with one heart with fast rotating purpose.When rotating left beaming roller, right beaming roller is fast together with the mind-set counter-rotation.
Can design chain by the utility model reverse concentric same speed rotary mechanism as required or not have two kinds of different structures of chain.(1) when using the transmission of two times mechanisms of chain conduct, left and right sides sprocket wheel and foot-operated is loaded onto in the outer end of left and right sides beaming roller, when stepping left threading, left side sprocket wheel drives flywheel by chain advances car, at this moment the moving connecting shaft awl of the left tapered cingulum on left beaming roller tooth rotates, make right tapered teeth directional opposite sense uniform movement, make right sprocket wheel return.Step on right threading again, right sprocket wheel drives flywheel by chain advances car, and the right tapered tooth on the at this moment right beaming roller makes left tapered teeth directional reversing sense motion by the tapered tooth of connecting shaft.Thereby make the revolution of left sprocket wheel, so just can about step and ride the driving bicycle running.Also positive dirction on one side simultaneously, on one side reversing sense step on to ride and make the car cruising.(2) when adopting no chain-driving, foot-operated about loading onto, and on the left and right conical tooth on the opposite of the connecting shaft awl tooth of reverse concentric same speed rotary mechanism, respectively adorn one with the tapered tooth of its ingear, by tapered tooth power is sent to rear axle and drives bicycle running, its function is with that chain is arranged is the same.
Adopt the utility model can design the bicycles that chain arranged or do not have chain more, make its more reasonable structure, more comfortable by bike.
Description of drawings
Fig. 1 is the structural representation of reverse concentric same speed rotary mechanism.
