Abstract
The utility model relates to a driver for a bicycle, which has a cocurrent drive system and an inverted drive system. The chainwheel and flywheel of one set of drive system all are installed on the inner side of a chain to constitute the cocurrent drive system. The chainwheel and the flywheel of the other set of drive system are respectively installed on two sides of the chainto constitute the inverted drive system. The utility model is suitable for a two-wheel pedal bicycle, a three-wheel pedal bicycle or a hand power trolley. The utility model has no need of manual shifting operation. The speed of the utility model can be changed by changing a drive direction.
Description
The utility model relates to the driving device of the wheeled car that is suitable for the rider driving specially, especially comprises wheel and the three-wheel of chain or the driving device of two wheel bicycles of different size.
Requirement based on road conditions and rider, often need this type of vehicle to move with friction speed, no doubt can regulate the speed of a motor vehicle with the method that changes rider limb motion speed, but because the set of the housing construction of rider, too fast slow excessively motion all is not suitable for and fatiguability, so people have studied various transmission systems so that can travel and can adapt to the speed of physical activity with proper speed.The patent No. is that 89212066.5 utility model patent is exactly a kind of device of adjustable two kinds of speed of a motor vehicle, and its actuating device has two strands, and variable speed operation need be used artificial joystick.
The purpose of this utility model is to disclose a kind of double-stranded actuating device that manual manipulation can be selected moving velocity as required voluntarily that need not.
The utility model is a kind of double-stranded actuating device of bicycle, chain belt transmission system with the different converter speed ratios of two covers, every cover driving system all contains the sprocket wheel that is contained in the axis place, be contained in the flywheel on the trailing wheel (drive wheel) and the chain of contact sprocket wheel and flywheel, it is characterized in that the sprocket wheel of the first cover driving system and the same side (inboard) that flywheel is contained in chain constitute transmission in the same way, flywheel is identical with the sprocket rotation direction; The second cover driving device middle sprocket and flywheel are contained in the both sides of chain respectively, constitute reverse transmission, and flywheel is opposite with the sprocket rotation direction.
Because the transmission direction of two cover driving systems of the present utility model is opposite, do not have the wheel rider with which side to driving, it is mode of operation that one cover driving system is always arranged, drive wheel is advanced, and another set of driving system is a sliding state, be the core and the cover slide relative of its flywheel, when driving direction changes, two cover driving systems are become by operating conditions respectively and slide attitude or become operating conditions by sliding attitude, therefore as long as change driving direction, be that pin is stepped on forward and changed into to post legged, or hand shakes forward to change into shaking backward and just can overlap driving system from certain and change another set of driving system work into, again because of the converter speed ratio difference of two cover driving systems, is accompanied by driving direction and changes, cause the selection of driving system, also just changed road speed.Just change the speed of a motor vehicle voluntarily as long as rider changes driving direction (sense of motion of pin or hand) like this, and need not the manual handling gear shift.Hereinafter will and contrast accompanying drawing and at large disclose the utility model by embodiment.
Description of drawings:
Fig. 1 is the stravismus scheme drawing of embodiment;
Fig. 2 is flywheel, minor sprocket and chainlet wheel carrier and the scheme of installation on wheel hub thereof of reverse drive system.
Embodiment is that a cover is installed in the double-stranded actuating device on the bicycle, it has the sprocket wheel of comprising 3, first cover of chain 4 and flywheel 5 and contain sprocket wheel 6, the second cover driving system of chain 7 and flywheel 8, please see Figure 1, sprocket wheel 3 together is contained in axis 9 right sides together with right crank 1, chain 4 is enclosed within the outside of sprocket wheel 3 and flywheel 5, and flywheel 5 is contained in trailing wheel (not shown) right side, constitute one and overlap driving system in the same way, it is the first cover driving system mentioned above, it is that deceleration system is used to go slowly that the ratio of number of teeth of sprocket wheel 3 and flywheel 5 is about 20:48, sprocket wheel 6 is positioned on axis 9 left sides together together with left crank 2, be contained in chain 7 on the sprocket wheel 6 by being contained in the minor sprocket 11 on the chainlet wheel carrier 10,12 contact flywheels 8, and flywheel 8 is contained in the trailing wheel left side, constitute a reversing sense driving system, be the second cover driving system mentioned above, sprocket wheel 6 is about 48:20 with the flywheel ratio of number of teeth, is that accelerator device is used for fastrunning.Certain this actuating device can not only be used for two and take turns bicycle, is equally applicable to three-wheel vehicle, handcar, drives the crank place as long as sprocket wheel 3,6 is positioned on, and flywheel has been contained on the drive wheel (perhaps on the semiaxis) just.Minor sprocket the 12, the 11st for tension chain 7 is provided with, is installed in the both sides up and down that are positioned at flywheel 8 on the chainlet wheel carrier 10.
Claims (2)
1, a kind of double-stranded actuating device of bicycle, chain belt transmission system with the different converter speed ratios of two covers, every cover driving system all contains the sprocket wheel that is contained in the axis place, be contained in the flywheel on trailing wheel/drive wheel and the chain of contact sprocket wheel and flywheel, it is characterized in that the sprocket wheel of the first cover driving system and the inboard that flywheel all is contained in chain, constitute driving system in the same way; The second cover driving device middle sprocket and the both sides that fly to be contained in respectively chain constitutes the reverse drive system.
2, device according to claim 1 is characterized in that the sprocket wheel side of reverse drive system is provided with the chainlet wheel carrier, and the both sides up and down that two minor sprockets are in flywheel respectively are housed on the chainlet wheel carrier.
