Description
Technical field
The utility model is related to a kind of bicycle synchronous belt flywheels.
Background technology
It is carried forward energetically under environmentally protective situation with international and domestic, people are engaged in short distance traffic activity, and bicycle is best
The vehicles of selection, not only environmental protection but also body-building, use scope is quite wide, and the movement of existing front wheel mainly passes through trailing wheel
It drives, big sprocket wheel is installed in trailing wheel, crank is installed in big sprocket wheel, foot pedal is installed on crank, is driven by foot pedal
Big sprocket wheel rotates, and big sprocket wheel is realized by a chain link with minor sprocket again, and then bicycle moves.
Chain is often blocked and is fallen off current but existing this technology bicycle during use, to meeting
Lead to the inconvenience in ride, while chain is easy to clamp trousers, is easy to stave trousers or damage trousers, and also need
Periodically chain to be given to add lubricating oil.
Utility model content
In view of this, the utility model aim is to provide a kind of cooperation by synchronous belt flywheel and free wheel base so that ride
Trousers will not be not only clamped during row, but also are not necessarily to oil lubrication, convenient bicycle synchronous belt flywheel of riding using process.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is：A kind of bicycle synchronous belt flywheel, including
There is synchronous belt flywheel, and is set to free wheel base inside synchronous belt flywheel, being fixedly connected with synchronous belt flywheel, the free wheel base
Inner surface offers the shaft through-hole for placing bearing, is provided on the outside of the synchronous belt flywheel and is integrally formed with synchronous belt flywheel
, flywheel gear for engaging synchronous belt, the both sides of the synchronous belt flywheel be respectively arranged with it is being fixedly connected with free wheel base,
Protective cover for protecting synchronous belt flywheel, the protective cover surface are provided with the screw for fixed blade guard, the protection
It is connected by screw between cover.
Preferably, the screw is provided with more than one, and it is uniformly distributed in the upper surface of protective cover.
Preferably, the flywheel gear is provided with more than one and is equally spaced on the outside of synchronous belt flywheel.
Preferably, the flywheel seating face is provided with groove.
Preferably, the groove is provided with more than one and is uniformly distributed in free wheel base outer surface.
The utility model has the technical effect that following aspect：Due to being provided with matching for synchronous belt flywheel and free wheel base
It closes, can be meshed with the groove of closed ring rubber belt by the center arbor on synchronous belt flywheel, to transmit movement and move
Power, and then replaced out the chain used in standard bicycle so that bicycle not will produce sliding in ride, not only have
Accurate transmission ratio, and rotational efficienty is high, gear range is big, while it being set to the protective cover of both sides in synchronous belt flywheel,
It can be effectively protected the destruction that synchronizing belt gear is not damaged, and prevents trousers from being generated by folder, extend synchronous belt
The service life of gear, have it is simple in structure, noise is small, wearability is good, without oil lubrication, in the presence of a harsh environment also can normal work
Make, is almost non-maintaining.
Description of the drawings

Fig. 2 is a kind of front view of bicycle synchronous belt flywheel of the utility model；
Fig. 3 is a kind of sectional view of bicycle synchronous belt flywheel of the utility model.
Specific implementation mode
Below in conjunction with attached drawing 1-2, specific embodiment of the present utility model is described in further detail, so that the utility model
Technical solution is more readily understood and grasps.
In the present embodiment, it is to be understood that term " centre ", "upper", "lower", " top ", " right side ", " left end ",
" top ", " back side ", " middle part ", etc. instructions orientation or positional relationship be based on the orientation or positional relationship shown in the drawings, only
It is of the invention for ease of description, does not indicate or imply the indicated device or element must have a particular orientation, with spy
Fixed azimuth configuration and operation, therefore be not considered as limiting the invention.
In addition, the connection between component or fixed form if not otherwise specified in this embodiment, connection or solid
Determine mode can be fixed by bolt commonly used in the prior art or pin fix or axis pin connection etc. modes, therefore, this
It is not described in detail in embodiment.
A kind of bicycle synchronous belt flywheel includes as shown in Figs. 1-3 synchronous belt flywheel 1, and be set to synchronous belt flywheel
Free wheel base 2 inside 1, being connect by left hand thread with synchronous belt flywheel 1,2 inner surface of the free wheel base are offered for putting
Set the shaft through-hole 22 of bearing, 2 surface of free wheel base setting fluted 21, the groove 21 be provided with more than one and uniformly
Be distributed in the outer surface of free wheel base 2,1 outside of the synchronous belt flywheel be provided with synchronous belt flywheel 1 it is integrally formed, for nibbling
The flywheel gear 11 of synchronous belt is closed, the flywheel gear 11 is provided with more than one and is equally spaced in outside synchronous belt flywheel 1
Side, the both sides of the synchronous belt flywheel 1 be respectively arranged with it is being connect by screw 4 with synchronous belt flywheel 1, for protecting synchronous belt
