Abstract

The present utility model discloses a kind of bicycle double-strand wheel transmission device for being installed to sprocket wheel after cycle hub.Including the first sprocket shaft, second sprocket shaft and third sprocket shaft, first sprocket shaft is pedal drive shaft, third sprocket shaft is bicycle rear axis of travel, sprocket shaft is equipped with toothed disc, sprocket wheel between centers is connected by chain drive, it is characterized by: first sprocket shaft is equipped with double gear panel, the double gear panel of first sprocket shaft passes through the toothed disc transmission connection on chain and the second sprocket shaft, the toothed disc being sequentially connected with third sprocket shaft is equipped among second sprocket shaft, second sprocket shaft center tooth wheel disc passes through the Flywheel disc chain drive on chain and third sprocket shaft, the rotation of flywheel dish driving bicycle rear.The utility model have many advantages, such as to ride stablize it is laborsaving, improve riding speed and avoid chain releasing.

Description

Bicycle double-strand wheel transmission device
Technical field
The present utility model is related to a kind of rear sprocket assembly for bicycle, and one kind being installed to chain after cycle hub The bicycle double-strand wheel transmission device of wheel.
Background technique
Current most of bicycles realize cycling using the rotation of chain drive bicycle rear hub, pass through foot pedal Sprocket wheel rotation before driving, preceding sprocket wheel realize that bicycle is transported forward by the flywheel turns that chain drive directly drives bicycle rear hub Row, preceding sprocket wheel are a toothed disc, and sprocket wheel is driven the side that bicycle rack is arranged in, not only laborious in riding also to influence to ride Stabilization.
Summary of the invention
The purpose of the present utility model is to overcome the deficiencies of the prior art and provide a kind of laborsaving stable bicycle of riding Double-strand wheel transmission device.
The utility model is achieved through the following technical solutions:
A kind of bicycle double-strand wheel transmission device, sprocket transmission device are mounted on bicycle frame, including the first sprocket wheel Axis, the second sprocket shaft and third sprocket shaft, the first sprocket shaft are pedal drive shaft, and two sprocket shafts are transmission axle, third sprocket wheel Axis is bicycle rear axis of travel, and sprocket shaft is equipped with toothed disc, and sprocket wheel between centers is connected by chain drive, it is characterised in that: First sprocket shaft is equipped with double gear panel, and the double gear panel of the first sprocket shaft passes through the tooth on chain and the second sprocket shaft Wheel disc transmission connection, the second sprocket shaft centre are equipped with the toothed disc being sequentially connected with third sprocket shaft, the second sprocket shaft center tooth Wheel disc reduces chain releasing, avoids trampling by the Flywheel disc chain drive on chain and third sprocket shaft, multi-chain gear wheel transmission Idle running;Be further described to above-mentioned technical proposal: the double gear panel diameter on first sprocket shaft is greater than the second chain Wheel shaft gear disk diameter improves riding speed;Above-mentioned technical proposal is further described: on first sprocket shaft Double gear panel is symmetricly set on the two sides of sprocket shaft, and double gear panel is ridden more stable when being arranged;Above-mentioned technical proposal is made into one The explanation of step: the diameter of the two sprocket shaft center tooth wheel discs is greater than the flywheel disk diameter on third sprocket shaft, and Flywheel disc drives Dynamic bicycle rear rotation.
The present utility model have the characteristics that ride stablize it is laborsaving, improve riding speed and avoid chain releasing.
Detailed description of the invention
Fig. 1 is Double sprocket-driven bicycle structural schematic diagram.
Fig. 2 is bicycle double chain wheel transmission structures figure.
Fig. 3 is bicycle double-strand wheel transmission device side view.
Fig. 4 is bicycle double-strand wheel transmission device scheme of installation (one).
Fig. 5 is bicycle double-strand wheel transmission device scheme of installation (two).
In figure: chain wheel driving mechanism 1, bicycle rear drive sprocket 2, the first sprocket shaft 3, the second sprocket shaft 4, third sprocket shaft 5, bicycle frame 6, chain 7, pedal 8 and toothed disc 9.
Specific embodiment
The content of the utility model is further described with reference to the accompanying drawing:
It as shown is bicycle double chain wheel transmission structures figure, including chain wheel driving mechanism 1, bicycle rear drive sprocket 2, the first sprocket shaft 3, the second sprocket shaft 4, third sprocket shaft 5, bicycle frame 6, chain 7, pedal 8 and toothed disc 9.
Driving chain wheel driving mechanism is made of 3 grades of sprocket shafts, and the chain transmission of 3 grades of sprocket shafts reduces the length of chain, Chain releasing is avoided, the first sprocket shaft is pedal drive shaft, and two sprocket shafts are transmission axle, and third sprocket shaft is bicycle rear Drive shaft uses double gear panel and two sprocket wheel axis connections on the first sprocket shaft, and double gear panel structure, which makes to ride, stablizes laborsaving, raising The rotating ratio between sprocket wheel is adjusted by the diameter of the toothed disc on setting sprocket shaft in riding speed, such as: on the first sprocket shaft Double gear panel diameter be 18cm, the pinion gear disk diameter on two sprocket shafts is 7cm, tramples the first sprocket shaft 1 circle, can make two chains Wheel shaft at least rotates 2.5 circles, and the diameter of the center tooth wheel disc on two sprocket shafts is 21cm, if 2.5 circle of rotation drives diameter 7cm's If flywheel turns, then flywheel will rotate 7.5 circles, above-mentioned parameter is for example, can be set according to actual requirement of riding The diameter of fixed tooth wheel disc.
