The reason of lower end is welded and fixed, welded connecting is three fixed points of left right end being capable of forming positioned at Same Latitude, and
The second bearing assembly 6 and fourth bearing assembly 8 connecting with forward and backward flexible axle sleeve 11 form two moving points.Five axis
It holds assembly upper end and is provided with steel wire traction ring 13, first wire 14 is set across first bearing assembly 5, the second axis
Hold assembly 6, the steel wire traction ring 13 on 3rd bearing assembly 7, wire 14 and first bearing assembly 5,3rd bearing
The steel wire traction ring 13 of assembly 7 is flexibly connected, and is fixedly connected with the steel wire traction ring 13 of second bearing assembly 6, while steel
The both ends of silk thread 14 are connected in the left speed change hand handle of bicycle by wiring；The same manner setting Article 2 wire 14 passes through
3rd bearing assembly 7, fourth bearing assembly 8, the steel wire traction ring 13 on 5th bearing assembly 9, wire 14 and
The flexible connection of steel wire traction ring 13 of three bearing assemblys 7,5th bearing assembly 9, leads with the steel wire of fourth bearing assembly 8
Draw ring 13 to be fixedly connected, while the both ends of wire 14 are connected in the right speed change hand handle of bicycle by wiring, by above-mentioned
Arrangement can adjust second bearing assembly 6, fourth bearing assembly 8 at two using the rotation of left and right speed change hand handle
Position between fixed point, so as to adjust the sphere gear 10 and speed-changing wheel disc that are similarly positioned on forward and backward flexible axle sleeve 11
The position that disk body 1 contacts achievees the purpose that double speed changes.In speed-changing wheel disc disk body 1 and 12 Contact Transmission of cardan-shaft tube, sphere
The contact increment of gear 10 can to the cylinder bullet block 2 on corresponding position speed-changing wheel disc disk body 1 apply active force, cylinder bullet block 2 with
It is shunk with contained spring 4, the cylinder bullet block 2 for pushing side not shrink by the tooth root of rotating sphere gear 10 at this time
Tooth top, because all cylinder bullet blocks 2 of speed-changing wheel disc are all, the columns of speed-changing wheel disc disk body 1 telescopic in a certain range
Body bullet block 2 can successively contact the continuous engaged transmission of guarantee with sphere gear 10.
Speed-changing wheel disc disk body 1 is separately positioned on the pedal shaft and rear-wheel shaft position of vehicle frame, first bearing assembly 5 and the 5th
Bearing assembly 9 is separately fixed at the both ends of gear axis and is equipped with mounting ring 15, speed change in its front of motor center
Both ends of the drive shaft passes through mounting ring 15 respectively and is fixed on foot-operated board shaft and hind axle, passes through scalable transmission shaft and forward and backward change
The contacting points position of fast wheel disc, which is adjusted, carries out double gearshift adjustments.Cylinder bullet block 2 and 10 contact jaw of sphere gear are smooth hemisphere,
10 engaged transmission of cylinder bullet block 2 and sphere gear.
The flexible position in the both ends of cardan-shaft tube 12 is set as triangular prism or elliptic cylindrical shape spline and flexible axle sleeve 11
Connection.Speed-changing wheel disc disk body 1 can change its size according to actual needs, ride board shaft and pass through sliding cross coupling and preceding speed change
Wheel disc axis body 3 connects, and rear speed-changing wheel disc axis body 3 is by ratchet and the ratchet cover plate and rear-wheel axis connection, so that bicycle rear follows
Speed-changing wheel disc axis body 3 rotates together afterwards.Double speed change steel wires can be connect with speed change hand handle, carry out speed change by speed change hand handle.
In the present invention, user is when using the kind of drive, when people steps on foot pedal, rides speed-changing wheel disc before board shaft drives
Rotation, the transmission shafts that the rotate driving of preceding speed-changing wheel disc contacts cover upper sphere gear rotation, the rotation of sphere gear
Power is provided for flexible transmission shaft rotation, the sphere gear of its tail portion is driven to rotate.Sphere gear drive in tail portion contacts
Speed-changing wheel disc rotates afterwards, and rear speed-changing wheel disc is to be fixed on the spoke of rear wheel, therefore rear-wheel is driven to be rotated, and drives whole
A bicycle walking.When needing speed change, it need to only be adjusted on the flexible transmission shaft being attached thereto by rotation speed change hand handle
Steel wire be just adjustable the positions of two flexible axle sleeves, adjust the position of sphere gear and speed-changing wheel disc therewith, thus to from
Driving carries out the double gearshift adjustments in front and back.
Advantage of the present invention also resides in which and is driven using the higher transmission shaft of stability, and has speed change function
Can, so that more stablizing using the bicycle of which durable, it can be adapted for more complicated landforms.And the module of the method
Change design, so that the product of the method can be adapted for the transformation of mostly shared bicycle, and daily maintenance is easy to maintenance, pole
Reduce human cost greatly.
The above is only not to make limit in any form to the present invention to better embodiment of the invention
System, any simple modification that embodiment of above is made according to the technical essence of the invention, equivalent variations and modification,
Belong in the range of technical solution of the present invention.
