Specific embodiment

Below in conjunction with attached drawing to specific implementation method of the invention, in the following description to some basic common axis It holds, axle sleeve, fastener etc., which is not described in detail, can be referred to as axis connection or the description understood by one of ordinary skill in the art such as hinged；It should Description is not intended to limit the invention to described example, which is intended to help to understand what the appended claims limited The contents of the present invention and method；

No chain conveyer method of the present invention is using parallelogram double leval jib principle, by one of bar and its two A endpoint is fixed, and when rotating other three bars, that bar on fixed link opposite remains the state parallel with fixed link, and with Fixed pivot is that rotary motion using another two on-fixeds pole length as radius is done in the center of circle；

The operation mechanism of no chain kit of the present invention is exactly principles above: as shown in Figure 1, of the present invention No chain kit includes: vehicle frame (01), axle or flower-drum (02), the short rocker arm| that no chain component and power intake are fixedly connected Bar (03), the short rocker arm| bar (04) with vehicle frame axis connection, long-armed treadle (05) are ridden (06)；By axle or flower-drum (02) (this axle Or flower-drum can be high speed flower-drum or variable-speed shaft) it is mounted on vehicle frame (01), the power intake of axle or flower-drum (02) at this time (be then shaft end if it is internal speed-changing flower-drum, then depend on the circumstances if it is outer speed change may be primary teeth wheel shaft shaft end) conduct One fixed pivot, the power intake of a short rocker arm| bar (03) and axle or flower-drum (02), which is fixedly connected, (can be key Connection is also possible to abnormity cooperation connection)；It is another on axis connection (can be with bearing or axle sleeve) on another fulcrum on vehicle frame again (certain unlimited short rocker arm| bar (04), preferably two are being illustrated short rocker arm| bar (04) with increasing the operation stability of mechanism In why do not draw, be for its prominent operation logic, preferably there are two short rocker arm| bar (04) in practical applications)；It is short to shake The other end all axis of armed lever (03) and short rocker arm| bar (04) are linked on two hinge joints of long-armed treadle (05), are thus formed Using two fulcrums on vehicle frame as the double leval jib of fixed pivot.

Depress foot-operated (06), long-armed treadle (05) transferred power to by short rocker arm| bar (03) and short rocker arm| bar (04) and The power input shaft end (07) of axle or flower-drum (02) that short rocker arm| bar (03) is fixedly connected, power passes through power input shaft end (07) power is passed on axle or flower-drum, band motor car wheel operates.

When foot-operated (06) reaches its lower limit, vehicle frame other side phase difference 180 degree without foot-operated on chain kit (08) Be exactly in the suitable position that can be ridden, depress at this time vehicle frame other side phase difference 180 degree without on chain kit (08) It is foot-operated, 360 degree of revolutions are just completed, so circulation is realized and continuously run.

The length of short rocker arm| bar refers to the distance of two hinged support central points on each short rocker arm| bar, short rocker arm| bar (03) Length with short rocker arm| bar (04) be in present design it is equal, so as to it is clearer description and understanding in this case, Long-armed treadle (05) may be implemented and entirely without in chain kit operation process, be able to maintain same angular pose always, effectively It avoids because of variation posture or is ridden caused by lengthening long-armed treadle (05) length and contacted to earth, applied in BMX up to pass weight It wants.

The length of short rocker arm| bar (03) and short rocker arm| bar (04) determines the entire radius of gyration of the no chain kit Amplitude, long-armed treadle (05) length determine the length of foot pedal arm force, by shortening short rocker arm| bar (03) and short rocker arm| bar (04) Length, can reduce the entire radius of gyration of the no chain kit；It, can be with by lengthening the length of long-armed treadle (05) The length for increasing foot pedal arm force, makes to ride more labor-saving；The two is used in combination, and in bicycle, BMX, scooter etc. is upper to have weight The realistic meaning wanted.

The no chain kit be included in vehicle frame other side phase difference 180 degree without chain kit (08), two sides Component realizes a complete rotary motion by 180 phase difference.

Short rocker arm| bar (04) in the no chain kit only denotes one in the accompanying drawings, it is therefore an objective to which everybody is easier The principle for understanding this programme, will increase in practical applications to 2 or 3 and increases the stability of long-armed treadle (05)；But In this case it is also not excluded for only using a short rocker arm| bar (04), such as want by short rocker arm| bar (03) and short rocker arm| bar (04) Be designed to different length achieve the purpose that long-armed treadle (05) different location have different angular poses, it is equally applicable The design.

The shape design of short rocker arm| bar (03) and short rocker arm| bar (04) in the no chain kit, which should be avoided, to be operated It prevents from interfering in journey；Its length is the radius of gyration required by car total to design.
