Abstract
A freewheel on a bicycle comprises an outer wheel body, an inner wheel body and a check ring, first balls are arranged on the left side of rachets and are positioned in a ball path surrounded by the inner and outer wheel bodies, second balls are arranged on the right side of the rachets and are positioned in a ball path surrounded by the check ring and the outer wheel body, the left side of the inner wheel body is provided with a thread connecting cylinder of which the outer diameter is equal to that of the outer wheel body, the inner surface of the thread connecting cylinder is provided with inner threads, and a circle of sprockets are arranged on the outer wheel body and are positioned right above the first balls. The freewheel on the bicycle has the beneficial effects that radial force sent from the sprockets directly acts on the first balls between the outer and inner wheel bodies, so that the second balls mainly bear varying stress brought by footboards, and the correspondingly borne varying stress of the second balls is minimum when the distance among the first balls and that among the second balls are the same.
Description
Technical field
The utility model relates to a kind of bicycle accessories, especially for the flywheel driving component on bicycle.
Background technique
Small flywheel prior art on bicycle generally all comprises an outer wheel body and interior wheel body, between interior wheel body and outer wheel body, is provided with two row's balls.Sprocket is all generally to be located in the middle of two row's balls, thereby makes left and right two row's ball uniform stresseds, but when interior wheel body and pedal shaft joint are positioned at outer wheel body one side, anti-like this rather than quite reasonable.
Summary of the invention
In order to overcome above deficiency, the utility model provides a kind of sprocket to be positioned at the flywheel on the bicycle on row's ball.
The technical scheme in the invention for solving the technical problem is: the flywheel on a kind of bicycle, comprise an outer wheel body, be arranged on the interior wheel body in outer wheel body, be arranged in the back-up ring on interior wheel body right side, described outer wheel body inwardly is provided with a circle ratchet, on described interior wheel body, aim at described ratchet and be hinged with very heavy top flat, between described very heavy top flat and interior wheel body, also be provided with stage clip, described stage clip presses to very heavy top flat, described very heavy top flat withstands ratchet, the left side of described ratchet is provided with the first ball, described the first ball is arranged in the rolling ball channel that wheel body and outer wheel body surround, the right side of described ratchet is provided with the second ball, described the second ball is arranged in the rolling ball channel that back-up ring and outer wheel body surround, described interior wheel body left side is provided with the cylinder that is threaded, a described external diameter that is threaded equals the foreign steamer body diameter, the described tube inner surface that is threaded is provided with internal thread, described outer wheel body is provided with a circle sprocket, described sprocket be positioned at the first ball directly over.
Further, the described cylinder outside that is threaded is provided with some blocks of being convenient to assemble.
Further, described block is provided with 4 and evenly annular around the cylinder setting that is threaded.
The utility model is connected to pedal shaft in use on the internal thread of the cylinder that is threaded and equally uses with existing flywheel, do not repeat them here, and be the first ball life-span of improving the sprocket below, can settle the ball that uses relative hardness and precision more to increase.
The beneficial effects of the utility model are: the radial force direct effect that sprocket transmits is to the first ball be positioned between foreign steamer body and wheel body, thereby what make the second ball mainly bears the varying stress of being brought by wood clapper, thus the varying stress minimum that makes same equidistant lower second ball of identical the first ball and the second ball should bear mutually.
The accompanying drawing explanation
Fig. 1 is an embodiment's of the utility model longitudinal sectional view.
Fig. 2 is an embodiment's of the utility model transverse sectional view.
Fig. 3 is an embodiment's of the utility model schematic diagram.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
By reference to the accompanying drawings 1 to 3, flywheel on a kind of bicycle, comprise an outer wheel body 1, be arranged on the interior wheel body 2 in outer wheel body 1, be arranged in the back-up ring 3 on interior wheel body 2 right sides, described outer wheel body 1 inwardly is provided with a circle ratchet 4, on described interior wheel body 2, aim at described ratchet and be hinged with very heavy top flat 5, 2 of described very heavy top flat 5 and interior wheel bodys also are provided with stage clip 6, described stage clip 6 presses to very heavy top flat 5, described very heavy top flat 5 withstands ratchet 4, the left side of described ratchet 4 is provided with the first ball 8, described the first ball 8 is arranged in the rolling ball channel that wheel body and outer wheel body surround, the right side of described ratchet is provided with the second ball 9, described the second ball 9 is arranged in the rolling ball channel that back-up ring and outer wheel body surround, described interior wheel body left side is provided with the cylinder 10 that is threaded, described cylinder 10 external diameters that are threaded equal outer wheel body 1 external diameter, described cylinder 10 internal surfaces that are threaded are provided with internal thread 11, described outer wheel body is provided with a circle sprocket 12, described sprocket 12 be positioned at the first ball 8 directly over.
Further, described cylinder 10 outsides that are threaded are provided with some blocks of being convenient to assemble 7.
Further, described block 7 is provided with 4 and evenly annular around the cylinder setting that is threaded.
The present embodiment is connected to pedal shaft in use on cylinder 10 the internal thread 11 that is threaded and equally uses with existing flywheel, do not repeat them here, and be the first ball life-span of improving the sprocket below, can settle the ball that uses relative hardness and precision more to increase.
The beneficial effect of the present embodiment is that radial force direct effect that sprocket transmits is to the first ball 8 be positioned between foreign steamer body and wheel body, thereby what make the second ball 9 mainly bears the varying stress of being brought by the step axle, thus the varying stress minimum that makes same equidistant lower second ball of identical the first ball and the second ball should bear mutually.
