Abstract
The utility model discloses a bicycle spring driving device which comprises a spring shell 2, a treading handle shaft 14, a treading handle 15, a chain disk 16 and power output shafts 10, wherein the treading handle shaft 14 runs through a shell of the spring shell, one side of the treading handle shaft 14 is provided with a ratchet gear 13 by a ratchet mechanism, the ratchet gear 13 is respectively meshed with spring driving wheels 1 which are arranged on both sides of the spring shell 2, the other side of the treading handle shaft 14 is provided with a gear 12, the chain disk 16 which is arranged on the gear 12 is connected with the treading handle shaft 14 in a freely rotating mode, and the gear 12 is respectively meshed with gears 11 arranged on the spring power output shafts 10 of both sides of the spring shell. By applying force to the treading handle 15, a driving assembly which is connected with the treading handle 15 leads the power output shafts 10 arranged on the spring device to finally drive the chain disk 16 to rotate, and the chain disk 16 is communicated with a flywheel of a bicycle, and therefore, the bicycle spring driving device has stable performance and high power conversion ratio.
Description
Technical field
The utility model relates to a kind of bicycle driving device, is specifically related to the device that a kind of spring motor drives bicycle freewheel.
Background technology
Bicycle is as walking-replacing tool or the existing history for many years of body-building apparatus.Engineering staff are pursuing the bicycle that a kind of energy-conserving and environment-protective, light actuating device are used to assemble always.In the prior art, as storage battery bicycle driven, variable speed bicycle or the like.
The utility model content
It is engine installation with the clockwork spring that the purpose of this utility model is to provide a kind of, is used to drive the actuating device that bicycle is advanced.
The utility model has adopted following technical scheme, the utility model by a clockwork spring shell 2, step on arbor 14, step on handle 15, chain drum 16, power take-off shaft 10 constitute; It is characterized in that: connect on the housing of clockwork spring shell 2 to install and step on arbor 14, a side of stepping on arbor 14 is equipped with ratchet gear 13 by a ratchet device, and this gear 13 meshes with the clockwork spring drive wheel 1 that both sides are provided with respectively; The described opposite side of stepping on arbor 14 is equipped with gear 12; And the chain drum 16 that is provided with on this gear 12, and step on arbor 14 and be freely and be rotationally connected; Described gear 12 respectively with the spiral spring power output shaft 10 of both sides on gear 11 engagements that are provided with.
Described clockwork spring shell 2 is the center to step on arbor 14, bilateral symmetry is equipped with spring motor, several inner shafts 3 of described spring motor are interlocked, ratchet 8,9 all is set on the inner shafts 3, the periphery 6 of inner shafts 3 is fixed with clockwork spring 5, the other end of clockwork spring 5 is connected mutually with clockwork spring shell 4, and the outer of clockwork spring shell 4 then links by axle sleeve 7 and clockwork spring shell 2.
After adopting such structure, by to stepping on handle 15 application of forces, connected drive element makes that the power take-off shaft 10 on the clockwork is final to drive chain drums 16 runnings; This chain drum 16 is connected with the flywheel of bicycle.Therefore, has stable performance, the characteristics that the power conversion ratio is higher.
Description of drawings
It shown in the accompanying drawing section-drawing of the utility model concrete structure.
