Abstract
The invention provides a back transmission device with the advantages that the structure is simple, and the defect of labor waste during the riding of an ordinary bicycle can be overcome, so the riding of the bicycle is labor-saving. A small chain wheel is arranged on a driving shaft in the transmission device, and is connected with a large chain wheel arranged on a driven shaft through a chain, the transmission ratio of the large chain wheel to the small chain wheel is about 1:1.5, and the small chain wheel is used for driving the large chain wheel to rotate, so the principle of output torque force increase of a speed reducing machine is realized. The transmission device is arranged on a bicycle frame, pedals and crank handles are arranged at the two ends of a driving shaft arranged inside the transmission device, a bicycle chain wheel is arranged at the outer end of the driven shaft and is connected with a flywheel through a bicycle chain, and the bicycle transmission running is completed, so the pedaling times and driving shaft rotating speed are respectively and properly increased and accelerated, and the increase of the output force of the bicycle chain wheel is realized, so the riding of the bicycle is labor-saving.
Description
Under technical field
The present invention relates to the device of transmission after a kind of bicycle, especially relatively simple for structure, can make cycling laborsaving.
Background technology
At present bicycle divides two-wheeled, three-wheel, have ordinary bicycle, mountain bike, three-wheel leisure and shipping bicycle etc. a variety of, and Electrical Bicycle is also accompanied with foot-operated transmission, effort relatively all while riding.What bicycle generally adopted at present is the rear transmission that chain connects, rear transmission is mainly made up of pedal and crank, sprocket wheel, chain, flywheel etc., after bicycle, transmission principle is firmly to step on pedal, drive sprocket rotation by crank, sprocket wheel rotates by chain-driving flywheel and trailing wheel, and promotes car front-wheel car is moved ahead.Mountain bike is chain rear wheel drive, and the number of teeth adjustment of multistage chain wheel and the multistage chain wheel of flywheel by sprocket wheel, also can reach the labor-saving effect of riding, but front and back regulate cumbersome difficult grasp, often regulate or regulate improper sprocket wheel easy to wear and flywheel chain wheel.
Summary of the invention
In order to overcome the deficiency of cycling effort, the invention provides one and make driving device behind cycling labour-saving, install again multistage flywheel additional and rear derailleur parts come after speed governing, realize bicycle and can improve again riding speed in the laborsaving while of riding, make bicycle can adapt to various road conditions and ride.
The technical scheme that the present invention solves the employing of cycling effort is: in this driver, minor sprocket is installed in imput shaft, connect and drive the hinge wheel of installing on driven shaft to rotate by chain, make it have the action principle of the raising output torque of reductor, large and small sprocket ratio is decided to be to 1: 1.5 left and right, thereby increase in right amount minor sprocket imput shaft rotating speed, obviously improved the output torque strength of hinge wheel driven shaft.Be fixed in after bicycle rack, outside this driver, both ends of main drive shaft is installed bicycle pedal and crank, and bicycle chainwheel is installed in driven shaft outer end, connects bicycle freewheel with cycle chain, completes the assembling of driver after bicycle.Bicycle is installed the effect that this driver plays, when identical with ordinary bicycle chain wheel speed, increase in right amount foot-operated number of times, when identical with ordinary bicycle sprocket wheel output strength, only need smaller foot-operated input strength, thereby make cycling more laborsaving.
The invention has the beneficial effects as follows, relatively simple for structure, the bicycle of this driver is installed, with the equal sprocket wheel of other bicycles and flywheel situation under, make cycling laborsaving.Installing on the bicycle of this driver, install again multistage flywheel and rear derailleur additional, just can make to carry out speed governing, can realize bicycle under the prerequisite of labour-saving, improve riding speed, and it is more laborsaving to make to ride, making bicycle adapt to various road conditions rides, compare the speed governing of mountain bike, operate simpler, the wearing and tearing that can alleviate sprocket wheel and flywheel.

Detailed description of the invention
In Fig. 3, driver minor sprocket 8 and bearing 12 are arranged on the position that imput shaft 7 makes, driver hinge wheel 10 and bearing 12 are arranged on the position that driven shaft 11 makes, they are connected with driver chain 9, be placed in driver 6 casings position customized, driver closed group is installed into, the large and small sprocket ratio of driver is 1: 1.5 left and right, make like this driver there is the characteristic of reductor, thereby improved output strength.Pedal and crank 1 are arranged on to the driver two ends of imput shaft outward, bicycle chainwheel are arranged on to the outer end of the outer driven shaft of driver.
In Fig. 2, driver 6 use screws by driver fixed orifice 13, are arranged on bicycle rack position, connect bicycle chainwheel 2 and flywheel 4 with cycle chain 3, this driver is installed on ordinary bicycle, bicycle can laborsavingly be ridden.Change installation multistage flying wheel at flywheel 4, and rear derailleur 5 is installed, can realize making to ride more laborsaving, can also improve riding speed.
In Fig. 4, driver shape can be made the long case shape of two ends arc, add moderate lubrication oil by driver oil hole 14, can play the various parts in lubricated driver, make it to rotate light and reduce wear, can regularly replace lubricating oil by driver outage 15, thereby extend the service life of the each parts of driver.
Claims (5)
1. make a driver behind cycling labour-saving, in the imput shaft in driver, be equipped with minor sprocket, on driven shaft, be equipped with hinge wheel, between have driver chain connect, in axle both sides, bearing is all housed, driver seals, and has oil hole and outage.
2. driver after bicycle according to claim 1, it is characterized in that: the imput shaft minor sprocket in driver drives driven shaft hinge wheel to rotate, thereby there is reductor and improve output torque power action principle, large and small gear multiplication in driver is decided to be to 1: 1.5 left and right, thereby increase in right amount the rotating speed of imput shaft miniature gears, obviously improve driven shaft big gear wheel output strength, realized cycling laborsaving simultaneously.
3. Bicycle driving device according to claim 1, the two ends of the imput shaft outside driver are made general, conventional bicycle crank and pedal can be installed, the driven shaft outer end of driver be made general, can select to install various conventional bicycle chainwheels.
