Abstract

The invention relates to the technical field of bicycle transmission devices, in particular to a transmission assembly, a bicycle transmission device and a bicycle. The transmission assembly comprisesa sliding rail, a movable pulley group, a fixed pulley group, a transmission chain and a rotating shaft; the movable pulley group comprises a first movable pulley and a second movable pulley; the transmission chain comprises a first transmission chain, a second transmission chain and a third transmission chain; one end of the first transmission chain is connected with a first sliding shaft; the other end of the first transmission chain is wound on the second movable pulley and the first movable pulley in sequence; by pulling the first transmission chain, the first movable pulley and the second movable pulley can be driven to oppositely move long the sliding rail; one end of the second transmission chain is connected with a second sliding shaft; the other end of the second transmission chain is wound on the fixed pulley group in sequence and connected with a rotating shaft; one end of the third transmission chain is connected with the first sliding shaft; and the other end of the thirdtransmission chain is connected with the rotating shaft to make the rotating shaft to rotate.

Description

technical field [0001] The invention relates to the technical field of bicycle transmission devices, in particular to a transmission assembly, a bicycle transmission device and a bicycle. Background technique [0002] Existing bicycles generally transmit the pedaling force from the crank and the sprocket to the flywheel and the rear wheel through the circular pedaling of the legs, thereby driving the bicycle to move forward. Therefore it is necessary to propose a transmission structure that can effectively increase the transmission ratio of the bicycle. Contents of the invention [0003] The object of the present invention is to provide a transmission assembly, a bicycle transmission device and a bicycle, so as to solve the technical problems in the prior art that the bicycle transmission structure has a large resistance and travel is relatively difficult. [0004] The invention provides a transmission assembly, including a slide rail, a movable pulley block, a fixed pull...
