Abstract

The utility model provides a double-body type sounding flywheel. The double-body type sounding flywheel is characterized in that an outer sprocket ring is connected with an inner core, an outer shell is arranged on the inner core in a buckled mode, an inner threaded hole is formed in the inner side of the outer shell, the circumferential inner wall of the outer shell is in a straight-tooth shape, at least two R-shaped jacking notches are formed in the edge of the inner core, at least three ball notches are formed in the inner wall of the inner core, balls are arranged in the ball notches, a groove is formed in the outer wall of the inner core in the circumferential direction, jacking plates are arranged in the jacking notches, a slope-shaped notch is formed in the tail end of each jacking plate, and O-shaped springs are arranged in the groove and the slope-shaped notches. According to the double-body type sounding flywheel, the outer sprocket ring can be more flexible when used in cooperation with the tooth shape of the outer shell, stable operation of the flywheel is guaranteed, and besides, the flywheel is simple in manufacturing process and reduces production cost greatly.

Description

The sound flywheel of double-body bike

Technical field

The utility model relates to the sound flywheel of a kind of double-body bike, is applied on bicycle.

Background technique

The flywheel used on standard bicycle, its complex structure, fabricating cost is high, is difficult for processing.Though the disclosed technological scheme of patent 200820012082.1 can address the above problem preferably, yet Shortcomings part still in actual production and while using, be flywheel when reversed operation, the roller on outer chain gear ring coordinates dumb with the profile of tooth on shell, the situation that cut-off is malfunctioning easily occurs.

The model utility content

The purpose of this utility model is to provide the sound flywheel of a kind of double-body bike, makes the profile of tooth on outer chain gear ring and shell more flexible when being used in conjunction with, and guaranteed the stable of flywheel, and this flywheel preparation process is simple, greatly reduces cost of production.

The technical solution of the utility model: the sound flywheel of double-body bike, outer chain gear ring is connected with inner core, shell is fastened on inner core, the inboard of shell is provided with interior threaded hole, the circumferential inner wall of shell is straight tooth-shaped, on the edge of inner core, be shaped with at least two very heavy notches of R type, on the inwall of inner core, be shaped with at least 3 ball notches, in the ball notch, ball is installed, edge circumferentially has groove on the outer wall of inner core, very heavy plate is installed in very heavy notch, the tail end of very heavy plate has a domatic breach, and O type spring plays the elastic force effect in groove and domatic breach.

The beneficial effects of the utility model: said structure is adopted in the invention, with flywheel in the past, compare, not only simple in structure, be convenient to processing, reduced the cost of making, and due to very heavy plate being installed in very heavy notch, the tail end of very heavy plate has a domatic breach, and O type spring, in groove and domatic breach, makes flywheel very heavy plate in the process of using coordinate flexibly with the straight tooth-shaped on shell, because steel ring has position-limiting action, make runnability good, stable simultaneously.
