Problems solved by technology
[0002] At present, the bicycle crank transmission mechanism that has been invented, the patent application number is 85103089, a kind of "telescopic crank mechanism for bicycles", which is a mechanism that produces a radial telescopic movement while the crank is doing circular motion; No. 85107618 "the propulsion mechanism of lever propelling bicycle" it is a kind of lever pedal system that rotatably installs, and there is shortcoming in the crank transmission mechanism of above-mentioned bicycle, and the former has increased motion circumference because crank radius is too long, causes Increase the stretching length of the legs, and the latter is not a regular circular motion, so that the cyclist makes a non-circular motion when riding a bicycle, which brings certain difficulties or inconvenience to the cyclist

Embodiment Construction
[0010] figure 1 , figure 2 , shown in Fig. 3 is that the specific embodiment of the present invention is characterized in that its structure is mainly made up of annular track 3, crank 4, central shaft drive 17, fixing device 18, left and right annular track 3 are groove-shaped tracks, The circular track 3 is located at both sides of the central axis 15 of the bicycle and is connected with the connecting bracket 2. The crank 4 is a straight rod-shaped crank composed of left and right crank connecting arms 5, connecting arm shaft 6, connecting arm pulley 7, and protective cover 8. The arm pulley 7 at one end of the crank 4 is located in the grooved track, and the other end is located between two rows of parallel crank guide wheels 12 in the central shaft drive 17; 10. The crank guide wheel 12, the guide wheel shaft 11, the central shaft drive base 13, and the fixed seat 14 are composed of the central shaft drive 17 located within the radius of the left and right symmetrical c...

A slide-type crank drive mechanism for bicycle is composed of an annular track with two symmetrical slot tracks, crank, driver of central axle and fixer. The slide wheel of connecting arm at one end of crank is positioned in slot track. Its another end is positioned between the guide wheels in said driver of central axle, which is in the radius of said annular track. Said driver of central axle has one end connected with central axle of bicycle. Its advantages are compact structure and saving labour.
Description
technical field [0001] The invention relates to a crank transmission mechanism of a bicycle, which is a new combination of a ring track and a crank sliding mechanism, and is fixed on both sides of the central axis of the bicycle and the tripod by an eccentric method. When the crank rotates around the circular track, it slides back and forth in the center shaft drive, and it is a bicycle sliding crank transmission mechanism that is driven during the reciprocating slide. Background technique [0002] At present, the bicycle crank transmission mechanism that has been invented, the patent application number is 85103089, a kind of "telescopic crank mechanism for bicycles", which is a mechanism that produces a radial telescopic movement while the crank is doing circular motion; No. 85107618 "the propulsion mechanism of lever propelling bicycle" it is a kind of lever pedal system that rotatably installs, and there is shortcoming in the crank transmission mechanism of above-mentione...
