Abstract
The utility model discloses a lever driving device for a bicycle, which comprises a right crank 3 which is fixed to a middle axle 1, the front end of a lever 4 which is arranged on the right crank 3, and a fulcrum shaft 5 which is fixed to a bicycle frame 13. A pinion 10 which is arranged on a back axle sleeve 11 is engaged with a gearwheel 9 which is arranged on the left side of a gear shaft 8, and a slide plate 10 is arranged on the right side of the gear shaft 8; in addition, the back end of the lever 4 is provided with a small shaft 6 which is arranged in a slot of the slide plate 10. The driving device with the structure is a function driving; compared with the existing chain driving, the utility model has the advantages of labor saving and big driving power.
Description
The utility model relates to a kind of bicycle rod gear.
The bicycle chain transmission is there to be the history in more than 200 year, and existing chain gear bicycle, easy chain-taking, period of service have been grown and can be out of shape and be elongated, the chain gear of garden shape sprocket wheel, and the variable force that does not also meet human body drives characteristics.
Non-chain gear bicycle sprocket drive spindle transmission and the transmission of treadle formula.Gear wheel shaft driving bicycle manufacturing cost height, and do not meet the characteristics that the variable force of human body drives.Treadle formula bicycle people will step lever up and down and could drive, and does not more meet the mode by bike of people's custom.
This practicality new with later-model from provide a kind of bicycle rod gear, promptly meet the characteristics that the human body variable force drives, and laborsaving big with transmission power.
In order to realize the purpose of above-mentioned utility model, adopted the bicycle rod gear.Right crank is fixedly mounted on the axis, and the front end of lever is installed on the right crank in the mode of running-fit.Fulcrum shaft is installed on the vehicle frame, and lever is crank motion between two turning cylinders of fulcrum shaft.Little axle is installed in the rear end of lever, little axle crank motion in the groove of chute board, and drive the chute board rotation.Chute board is installed in the right-hand member of gear wheel shaft, and the left end of gear wheel shaft is installed big gear wheel.Gear wheel shaft is installed on the vehicle frame in the mode of running-fit, big gear wheel and the pinion that is installed on the backshaft skin.
When driving right crank garden revolution, lever just swings up and down, and between two turning cylinders of fulcrum shaft crank motion.Little axle on the lever rear end also crank motion in slideway side plate groove, make chute board garden revolution, and make big gear wheel also along with the garden revolution, big gear wheel just drives the miniature gears garden revolution that is installed on the backshaft skin like this, formed the function transmission, thereby the trailing wheel that drives bicycle rotates.
After bicycle adopts this rod gear, owing to do not had chain, so do not have chain-taking and metaboly.Compare with the gear wheel shaft driving bicycle, it is simple in structure, and cost is low.Compare with the treadle formula bicycle that also utilizes lever principle to drive, treadle formula bicycle can only step lever up and down by both feet, could drive car and move ahead, and lever driven bicycle has overcome this shortcoming, the people can pedaled crank garden revolution, and the custom that meets people is mode by bike.
Because the bicycle rod gear is the function transmission, and the variable force that meets human body drives characteristics, thereby improved transmission power, and laborsaving.
The utility model will be further described below in conjunction with accompanying drawing and embodiment.
Fig. 1 is the birds-eye view of the rod gear structure of bicycle running part.
Fig. 2 is the front view that Fig. 1 marks lever drive mechanism figure.
Can be seen that by Fig. 1 the front end of lever 4 is installed on the axle of right crank 3, right crank 3 is fixedly mounted on the axis 1.Fulcrum shaft 5 is fixedly mounted on the frame 13.So do not draw because of vehicle frame has all as everyone knows.Rear axle 12 and gear wheel shaft 8 are installed on the vehicle frame 13, and backshaft skin 11 is installed on the axle 12.Miniature gears 10 is installed in the right side of backshaft skin 11, and big gear wheel 9 is installed in the left side of tooth axle 8, and chute board 7 is installed in the right side of gear wheel shaft.Little axle 6 is installed in the rear end of lever 4.But little axle 6 is placed on the interior crank motion of the groove of chute board 7.
See in Fig. 2, follow axis 1 not on same line of centers with the axle of lever 4 running-fits on the right crank 3, and become 90 ° of degree captive joints with the bar that right pedal 2 is installed, the bar of installation right pedal 2 is vertical with axis 1.
When right crank 3 garden revolution, lever 4 is swung up and down, and between two turning cylinders of fulcrum shaft 5 crank motion.Simultaneously, little axle 6 is crank motion in the groove of chute board 7 also, and drives chute board 7 garden revolution.Big gear wheel is also along with chute board 7 garden revolution together like this.Thereby make also garden revolution of the miniature gears 10 that is installed on the backshaft skin 11, and drive the trailing wheel garden revolution of bicycle.Bicycle is travelled forward.
Claims (2)
1, the bicycle rod gear comprises: be installed in right crank 3 upper levers 4, be fixedly mounted on fulcrum shaft 5 and the chute board 7 that is installed in gear wheel shaft 8 right sides on the vehicle frame 13, and be installed in little axle 6 on lever 4 rear ends, it is characterized in that: the front end of lever be installed in right crank 3 the axle on, lever 4 is crank motion between two turning cylinders of fulcrum shaft 5, little axle 6 crank motion in the groove of chute board 7 that install lever 4 rear ends.
2, as claim 1, described bicycle rod gear, it is characterized in that: follow axis 1 not on same line of centers with the axle of lever 4 running-fits on the right crank 3, and become 90 ° of captive joints with the bar that is installed in right pedal 2, the bar that right pedal 2 is installed is vertical with axis 1.
