Description
Technical field
The invention belongs to bicycle manufacturing technology field, more particularly to a kind of bicycle driving device.
Background technology
With the development in pluralism of society, bicycle is a kind of indispensable walking-replacing tool, the driving of bicycle be by
People's tap pedal rotates completion, and one end of crank is connected with axis in existing bicycle driving device, and axis also participates in
Transmission, i.e. the application point of power is nearer from the center of circle, therefore does not show the rotation advantage of output fully, i.e., roundlet (axis) drives great circle
(chain wheel), it is not laborsaving enough, easily cause the fatigue of cyclist.
Secondly, existing bicycle have one it is fatal the shortcomings that, i.e., it is extremely low in the drive efficiency of dead center, when voluntarily
When car crank is consistent with gravity direction, step pedal is most laborious, and here it is the dead point in mechanical engineering.When bicycle is flat
Or descending generally moves past dead point to overcome it when riding naturally by the inertia of bicycle crank, but when cycling speed compared with
During slow or upward slope, the problem is than more prominent, and because the direction of power and the direction of the arm of force are consistent at dead point, now kinetic moment is
Zero, thereby result in the very big waste of manpower.
The content of the invention
It is an object of the invention to provide a kind of bicycle driving device, by the way that one end of crank is directly installed on into chain wheel
On, as far as possible away from axis, the functioning efficiency that solves existing bicycle force is low, it is big to eliminate power used during dead point, using laborious
The problem of.
In order to solve the above technical problems, the present invention is achieved by the following technical solutions：
The present invention is a kind of bicycle driving device, including axis, the axis be arranged on the First Five-Year Plan it is logical in, the axis one
End is fixed with chain wheel, and the axis other end is fixed with bracket panel, and the surface of chain wheel one is fixed with a crank, the table of bracket panel one
Face is fixed with a crank, and the crank includes the first pivoted arm, the second pivoted arm and the 3rd pivoted arm, and one end of the 3rd pivoted arm is fixed
There is pedal.
Further, offered on the chain wheel and be engaged corresponding through hole with the first pivoted arm, first pivoted arm passes through
Through hole is riveted on chain wheel, is offered on the bracket panel and is engaged corresponding through hole with the first pivoted arm, and first pivoted arm passes through
Through hole is riveted on bracket panel.
Further, one end of first pivoted arm offers is engaged corresponding through hole with the second pivoted arm, and described first
The pivoted arm other end is provided with nut, and one end of second pivoted arm is riveted on the first pivoted arm by through hole, second pivoted arm
The other end offers is engaged corresponding screwed hole with the 3rd pivoted arm, and the 3rd pivoted arm both ends are equipped with screw thread, and the described 3rd
One end of pivoted arm is fixed on the second pivoted arm by way of screw thread and screwed hole are screwed, and the other end of the 3rd pivoted arm leads to
Cross to be screwed and have pedal.
Further, the crank on the crank and bracket panel on the chain wheel is on axis central point rotational symmetry.
Further, the through hole opened up on the chain wheel is to the distance between middle axis center and the length ratio of chain wheel radius
(0.7~0.9):1, the length ratio of the distance between through hole opened up on the bracket panel to middle axis center and bracket panel radius is (0.7
~0.9):1.
The invention has the advantages that：
1st, one end of crank is directly installed on chain wheel by improving drive device, makes the application point of power remote by the present invention
From the center of circle, it is connected different from existing bicycle crank one end with axis, direct rotary toothed disk, it is excellent shows the rotation contributed to chain wheel
Gesture, transmission efficiency, realize labor-saving effect.
2nd, the drive device after the present invention improves makes the position of new role point be higher than former application point, i.e. new role point is in more
Unstable poised state, therefore when eliminating dead point, power is smaller, that is, is easier to eliminate dead point.
3rd, the present invention is simple in construction, novel, and cost is not high, practical, does not change bicycle other original structures, extensively
The general manufacturing applied to bicycle, apply also for other manpower bicycles.
Certainly, any product for implementing the present invention it is not absolutely required to reach all the above advantage simultaneously.
