The invention discloses an integrated drive sprocket with a back riding function and convenient to disassemble, assemble and maintain. A left hub is arranged at the left end of a center shaft, a right hub is arranged at the right end of the center shaft, a driven disc is arranged on the right end face of the right hub, a drive disc is arranged on the right side of the driven disc, a bearing is arranged in the middle of the drive disc, the drive disc is installed on the center shaft located on the right side of the right hub through the bearing to be connected with the driven disc of the right hub into a whole, a reverse gear shaft pin hole is formed in the upper end of the right hub, a reverse gear bolt hole is formed in the upper end of the drive disc, and a reverse gear bolt is installed in the reverse gear bolt hole. According to the integrated drive sprocket with the back riding function and convenient to disassemble, assemble and maintain, the driven disc is arranged on the right end face of the right hub, a variable-speed wheel disc is combined with the hubs into a whole, when back riding is conducted, the reverse gear bolt screws into the reverse gear shaft pin hole formed in the upper end of the right hub, and back riding action can be carried out to conduct physical exercises with various techniques.
Description
technical field [0001] The invention relates to a walking-replacing bicycle, in particular to a conjoined drive sprocket with the function of riding backwards and being convenient for disassembly and maintenance. Background technique [0002] The bicycles sold and used in the market do not have the function of going backwards, but can only be ridden forward, and cannot be used as sports equipment to exercise the human body to strengthen the body and bring into play potential application functions. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defects and provide a one-piece sprocket with a reverse function to improve the application function of the bicycle and meet the needs of consumers. [0004] The solution of the present invention includes left and right hubs, a central shaft, and a driving disc. Its structural feature is that a left hub is provided at the left end of the central shaft, a right hub is provide...
