Abstract
A kind of bicycle wheel disc mechanism equipped with wind spring buffering torque fluctuations, suitable for manually driven bicycle, it can utilize and its internal wind spring is installed, the energy that Dynamic Absorption, release input, for the fluctuation of buffer foot power input, it is exported to which the pulsed pedal force of input is become relatively stable power, but also foot force application is soft, vehicle operates steadily.Wheel disc mechanism is internally provided with pawl, and wind spring is prevented to spring back.Bicycle wheel disc mechanism is additionally provided with clutch sliding bolt, and drive line, switching buffering transmission mode and common drive pattern can be changed.Epicycle disc mechanism is also applied for power source and exports unstable transmission mechanism.
Description
Technical field
In machine application, the output of various power sources has unstable phenomenon, especially with manually driven foot
The fluctuation of treadmill, output torque becomes apparent from.The fluctuation for reducing the output of power source torque is that mechanical transmission course needs are continuously improved
Technology.
Background technology
Very widely used today manpower drives bicycle, is to drive wheel disc then with motor-car by foot pedal, pedal crank
Wheel operation, the variation of arm of force length, the wave for necessarily bringing torque to export when due to the variation of human body force size, pedal crank rotation
It is dynamic.
Invention content
Present invention aims at a kind of bicycle wheel disc mechanisms of offer, defeated by wind spring absorption high-torque in transmission process
Then fashionable portion of energy releases again when input torque is small, as the supplement of driving moment, make to drive
Cheng Pingwen reduces fluctuation.
The present invention is made of three parts：First, foot pedal, pedal crank, rotation bolt；Second is that energy storage box, energy storage box is by interior
Cylinder, wind spring, outer barrel three parts composition, wind spring encloses to be engaged with outer barrel outer tube；Third, one-way clutch, passes through one-way clutch handle
Energy storage box outer barrel is connected with wheel disc.
To realize that torque output process is steady, reducing the purpose of fluctuation, solution of the invention is：The bicycle
Driving source square is inputed to the wind spring in energy storage box by wheel disc mechanism by foot pedal, pedal crank, rotation bolt, passes through the suction of wind spring
It receives, release, then is smoothly exported torque to wheel disc by one-way clutch, drive wheel.
The present invention program further includes：First, the inner cylinder of energy storage box is equipped with pawl, prevents inner cylinder from rotating backward, avoid machinery
It can reversely discharge.Second is that being additionally provided with clutch sliding bolt on pedal crank, clutch sliding bolt wind spring above-mentioned when leaving plays a role, and delays
Impulse moment makes torque steadily export；When clutch sliding bolt engages, then transmission process has masked the effect of wind spring, transmission process
It is identical as ordinary bicycle wheel disc effect.
The advantages of this invention, is：1, this bicycle wheel disc mechanism can be buffered defeated by the interior energy storage box wind spring set
Enter the size variation of torque, reduces fluctuation, keep output torque steady.2, the pedal crank of this bicycle wheel disc mechanism is equipped with clutch
Sliding bolt, for retaining the function of ordinary bicycle wheel disc, therefore there are two types of transmission modes to select.
Description of the drawings：
Fig. 1 is the structure chart of inner cylinder, wind spring, outer barrel, and Fig. 2 mainly shows that the drive line of two transmission modes, Fig. 3 are these
The overall diagram of invention.
Specific embodiment
With reference to the accompanying drawings and examples, the invention will be further described.
The present invention is provided with clutch sliding bolt 3, for realizing the conversion of two kinds of transmission modes.
First, buffering torque fluctuation model with wind spring：In clutch 3 leave state of sliding bolt, foot pedal 1 is stepped, drives foot
11 rotation of the second circle for turning 2, rotation bolt 10, concentric bearings 20 is stepped on, energy storage box inner cylinder 12 rotates, and wind spring 14 deforms upon, passes through
Wind spring 14 drives energy storage box outer barrel 6, since the rotation of outer barrel 6 opens voussoir 7, drives External Ring of One-way Clutch 8,9 turns of wheel disc
It is dynamic.Due to there is wind spring 14 in transmission process, portion of energy when high-torque input is absorbed, is released when small torque inputs
Exoergic amount is exported as supplement, plays the role of buffering, but also feeling when manpower pedal soft.Inner cylinder 12 is equipped with pawl
Pawl slot 16 on 13, with hollow middle shaft 17 coordinates, and inner cylinder 12 is prevented to invert, and ensures that torque input process is stablized.
Second is that ordinary bicycle wheel disc pattern：In clutch 3 engagement state of sliding bolt, foot pedal 1 is stepped, drives pedal crank
2, clutch sliding bolt 3, stir pillar 4 on the third circle 5 of concentric bearings 20, so that the rotation of outer barrel 6 is opened voussoir 7, drive unidirectional
Clutch outer shroud 8, wheel disc 9 rotate.This transmission process shields the effect of wind spring, identical as ordinary bicycle wheel disc effect.
The bicycle wheel disc mechanism is fixed in rack 19, and hollow middle shaft 17 is fixedly connected with rack 19, meanwhile, in hollow
The other side of axis 17 is connect by the 4th circle 15 of concentric bearings 20 with rack 19, and wheel disc is connected by bearing 21 and hollow middle shaft 17
It connects, concentric bearings 20 are fixed on hollow middle shaft 17, and the foot pedal 1 of both sides, pedal crank 2 inner shaft 22 connect, then pass through axis
18 are held to connect with hollow middle shaft 17.
Claims (1)
1. a kind of bicycle wheel disc mechanism equipped with wind spring buffering torque fluctuations is exported from foot pedal input power by wheel disc,
It is characterized in that：1, wheel disc mechanism is internally provided with inner cylinder, wind spring and outer barrel, engages from inside to outside, and pedal force passes through foot pedal, foot-operated
It turns, rotate bolt (10) driving inner cylinder, inner cylinder passes torque to wind spring, and wind spring is opened voussoir (7) with elastic force driving outer barrel and passed through
Wheel disc (9) exports, and the energy that wind spring Dynamic Absorption, release input is used for the fluctuation of buffer foot torque input, is equipped on inner cylinder
Pawl (7) prevents inner cylinder from rotating backward.2, it using the clutch sliding bolt (3) on pedal crank (2), engages, shields with pillar (4)
The effect of spring of rolling out restores the transmission mode of common wheel disc, realizes the switching between common drive and buffering transmission both of which.
