Abstract
The utility model relates to a bicycle, in particular to a novel transmission device of the bicycle. The novel transmission device of the bicycle comprises two middle axle wheels, two rear axle wheels and two transmission strips. The two middle axle wheels are installed at the left end and the right end of a middle axle and are located on the two outer sides of a bicycle frame. The two rear axle wheels are installed at the left end and the right end of a rear axle and located on the two inner sides of the bicycle frame. The transmission strips are assembled with the middle axle wheels and the rear axle wheels to form a transmission chain. Each middle axle wheel is provided with an annular groove used for containing one transmission strip and a radial groove perpendicular to the annular groove. The novel transmission device of the bicycle has the advantages that the middle axle wheels, the rear axle wheels and the transmission strips form the transmission chain; the middle axle wheels replace chain wheels, the rear axle wheels replace fly wheels, and the transmission strips replace chains, so that the manufacturing cost of parts is lowered; as the two middle axle wheels, the two rear axle wheels and the two transmission strips are included, downward pedaling force of the two feet can be fully utilized, and a rider can feel effortless; the transmission strips are arranged on the left side and the right side respectively, even when one transmission strip is off during riding, the other transmission strip is not off, and then riding danger can be prevented.
Description
Technical field
The utility model relates to bicycle.
Background technology
Existing bicycle drive, only be provided with chain wheel, flywheel and chain on vehicle frame the right.Ordinary bicycle only has a chain wheel, a flywheel and a chain.Though variable speed bicycle has a plurality of chain wheels, a plurality of flywheel, also only has a chain.People by bike the time, be mainly right crus of diaphragm firmly, right crus of diaphragm is firmly stepped on stretcher, is in right steps in 180 degree half-turn scopes from the vertex to the nadir, another half-turn right crus of diaphragm has not just been used power; Now left foot firmly, is delivered to chain wheel, chain, the flywheel on the right again by crank, axis, and power can decay in transmittance process.The right is provided with chain wheel, flywheel and chain, and Zuo Bian No has, and can aggravate wearing and tearing on one side.Only have the chain in the right, if fallen chain in the process of riding, must stop riding even to go out danger.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point and driving device that a kind of new bicycle is provided, this device contains arbor wheel after two middle arbor wheels, two, two transmission bars, replace chain wheel with middle arbor wheel, rear arbor wheel replaces flywheel, the transmission bar replaces chain, can reduce the manufacturing cost of parts.Middle arbor wheel, in the whole circle rotation process of 360 degree, is pedaled the power utilization abundant under the bipod of left and right, the left and right balance, ride comfortable, feels laborsaving.
The utility model adopts following technical scheme.
A kind of driving device of new bicycle, include the axis and the rear axle that are arranged on cycle frame, also include arbor wheel after two middle arbor wheels, two, two transmission bars, two middle arbor wheels are arranged on the left and right two ends of axis and are positioned at two outsides of vehicle frame, after two, arbor wheel is arranged on the left and right two ends of rear axle and is positioned at two inboards of vehicle frame, and transmission bar and middle arbor wheel and rear axle wheel combine messenger chain.Middle arbor wheel is provided with the circular groove that contains the transmission bar, on middle arbor wheel circumference, offers the radial slot vertical with circular groove.In the circular groove of middle arbor wheel, molar is arranged.
The utility model has the advantage of: the bicycle drive of prior art, include chain wheel, flywheel and chain, combine messenger chain.This device by arbor wheel, rear arbor wheel, transmission bar combine messenger chain.Replace chain wheel with middle arbor wheel, rear arbor wheel replaces flywheel, and the transmission bar replaces chain, can reduce the manufacturing cost of parts.This device contains arbor wheel after two middle arbor wheels, two, two transmission bars, and people are by bike the time, and middle arbor wheel, in the whole circle rotation process of 360 degree, is pedaled the power utilization abundant under the bipod of left and right, and the left and right balance, ride comfortable, gives the labour-saving sensation.The right and left has middle arbor wheel, rear arbor wheel, transmission bar, symmetrical configuration, and stress equalization, can reduce or prevent that uneven wear from exaggerating.Respectively there is a transmission bar left and right, even fallen one in riding, also has one and does not fall, and can prevent ride danger and burst accident.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation birds-eye view;
The structural representation front view of arbor wheel in Fig. 2;
The birds-eye view that Fig. 3 is Fig. 2;
The A-A that Fig. 4 is Fig. 3 analyses and observe view.
The specific embodiment
With accompanying drawing, the utility model is further described in conjunction with the embodiments.
Referring to Fig. 1, a kind of driving device of new bicycle, include the axis and the rear axle that are arranged on cycle frame, also include after two middle arbor wheels 1, two arbor wheel 5, two transmission bars 6, two middle arbor wheels are arranged on the left and right two ends of axis 2 and are positioned at two outsides of vehicle frame, after two, arbor wheel is arranged on the left and right two ends of rear axle 4 and is positioned at two inboards of vehicle frame, and transmission bar and middle arbor wheel and rear axle wheel combine messenger chain.
Referring to Fig. 2 to Fig. 4, middle arbor wheel 1 is provided with the circular groove 11 that contains the transmission bar, and the transmission bar is inserted in circular groove.Offer the radial slot vertical with circular groove 12 on middle arbor wheel circumference.Described circular groove can be V-arrangement, U-shaped or circular arc.The present embodiment is U-shaped.
Rear arbor wheel is the same with middle arbor wheel, also is provided with the circular groove and the radial slot vertical with circular groove that contain the transmission bar, and molar is also arranged in circular groove.The diameter of rear arbor wheel is less than middle arbor wheel.
The inner hole structure of middle arbor wheel reaches with the installation of axis and is same as existing chain wheel.
The inner hole structure of rear arbor wheel reaches with the installation of rear axle and is same as existing flywheel.
