Abstract
The utility model discloses a bicycle with planet gear lever transmission, comprising a sliding way board 5 fixedly connected with a bicycle frame 4. A crank axle 2 is arranged in the middle joint of the bicycle frame 4. The axle on the right end of the crank axle 2 is provided with a lever 3 and a right crank 1. The fulcrum axle 6 on the lever 3 is placed in the slot of the sliding way board 5 and the small axle on the lever 3 is placed in the slot of a rotatable board 8. The rotatable board 8 and an inner gear 11 are connected together and rotate together. A planet gear rack 10 is fixed on a positioning table 9 and can not rotate. A planet gear 12 is arranged on the planet gear rack 10 and engaged with the inner gear 11 and also engaged with the center gear 13 arranged on a back axle hub 14 and drives the back wheel of the bicycle to conduct circumference rotation by the back axle hub 14 to enable the bicycle to forward move. The transmission structure conforms to the requirements of human body dynamics and the ride habit with non-linearity transmission, high transmission efficiency, labor saving and rapid speed.
Description
Affiliated technical field
The utility model relates to a kind of planetary wheel lever driven bicycle.
Background technology
Existing in 1 hundred 30 history of bicycle chain transmission, the chain gear bicycle falls chain easily, driving efficiency is low and poor stability, and the chain gear of circular chain-wheel does not meet body mechanics's driving requirement yet.
Non-chain gear bicycle, existing gear wheel shaft transmission and the transmission of treadle formula.Gear wheel shaft driving bicycle manufacturing cost height, and do not meet body mechanics's driving requirement.Treadle formula bicycle will step lever up and down back and forth and could drive, and does not more meet the mode by bike of people's custom.
Summary of the invention
The purpose of this utility model provides a kind of bicycle with the transmission of planetary wheel lever.Not only met requirement that the body mechanics drives, but also laborsaving, driving efficiency is high and low cost of manufacture.
In order to realize the purpose of above-mentioned utility model, adopted the planetary wheel rod gear.Bent axle is installed in the vehicle frame center tap in the mode of running-fit, and the front end of lever also is installed on the axle of bent axle right-hand member in the mode of running-fit, and crank is fixedly mounted on the square toes of right-hand member of bent axle.Chute board is fixedly connected on the vehicle frame, the fulcrum shaft of lever can be in the groove of chute board crank motion, little axle is installed in the rear end of lever, little axle can be in the groove of rotor plate crank motion, and rotor plate is rotated, rotor plate and inner gear link together, inner gear and the planetary wheel engagement that is installed on the star wheel frame, star wheel frame is fixedly mounted on the positioning table, planetary wheel and the sun gear engagement that is installed on the backshaft skin.
When driving the rotation of bent axle circumference, the lever front end just swings up and down, and pulling fulcrum shaft crank motion in the groove of chute board, the little axle that makes lever rear end is crank motion in the groove of rotor plate also, drive rotor plate and inner gear circular movement together, and the direction of rotation of rotation direction and bent axle.Planetary wheel engagement on inner gear and the star wheel frame, star wheel frame is fixedly mounted on the positioning table, and planetary wheel meshes with sun gear again, and sun gear is installed on the backshaft skin, thus the trailing wheel that drives bicycle rotates, and formed non-linear transmission.
After bicycle adopts the transmission of this planetary wheel lever owing to there has not been a chain, just do not exist to fall yet chain and poor stability shortcoming.With the gear wheel shaft driving bicycle relatively, that the epicyclic gear transmission bicycle has is simple in structure, cost is low, laborsaving advantage.Compare with treadle formula bicycle, though it also utilizes lever principle, it can only step lever up and down by both feet, could drive trailing wheel rotates, and the planetary wheel lever driven bicycle has overcome this shortcoming, and is the same with the mode that scrunches of chain gear bicycle, and the custom that meets people is mode by bike.
Because the planetary wheel lever driven bicycle is a principle of utilizing lever, meets people's mode of riding and body mechanics's requirement, thereby improved driving efficiency, and reached the labour-saving purpose.
Description of drawings
The utility model will be further described below in conjunction with accompanying drawing and embodiment.
Accompanying drawing is a planetary wheel lever driven bicycle running part structure diagram
Can see by accompanying drawing, the front end of lever 3 is installed on the right-hand member axle of bent axle 2, the square toes of bent axle 2 right-hand members fixedly mount right crank 1, one end of fulcrum shaft 6 is fixed on the lever 3, the other end is placed in the groove of chute board 5, chute board 5 is fixedly connected on the vehicle frame 4, because of vehicle frame 1 well-known, so all do not draw, an end of the little axle 7 of the rear end of lever 3 fixed installation, the other end of little axle 7 is placed in the groove of rotor plate 8, rotor plate 8 and inner gear 11 link together, inner gear 11 and the planetary wheel 12 that is installed on the star wheel frame 10 mesh, and pinion carrier 10 is fixed on the positioning table 9, and planetary wheel 12 and the sun gear 13 that is installed on the backshaft skin 14 mesh.
The specific embodiment
When stepping right crank 1, bent axle 2 moves in a circle, lever 3 is that fulcrum swings up and down with fulcrum shaft 6, the other end of fulcrum shaft 6 is crank motion in the groove of chute board 5, simultaneously, little axle 7 on the rear end of lever 3, also crank motion in the groove of rotor plate 8, and drive rotor plate 8 also moves in a circle, the direction of rotation of rotor plate 8 and bent axle 2, inner gear 11 and rotor plate 8 link together, and both rotate together, star wheel frame 10 is fixed on the positioning table 9, can not rotate, planetary wheel 12 is installed on the star wheel frame 10, and meshes with inner gear 11, also with sun gear 13 engagements that are installed on the backshaft skin 14, so when inner gear 11 circumference rotated, planetary wheel 12 and sun gear 13 also circumference rotated inner gear 11 and sun gear 13 direction of rotation, and pass through the trailing wheel circumference rotation that backshaft skin 14 drives bicycles, bicycle is travelled forward.
