Problems solved by technology

[0002] The traditional bicycle is a chain transmission, and the transmission mechanism composed of a large chainring, a chain, and a chain flywheel has many disadvantages: because the chain wheel of the chain transmission is large at the front and small at the rear, the pulling direction of the chain is not parallel to the direction of motion, resulting in force components ;The sagging of the chain will cause the force between the links and the direction of movement and the angle to be different to produce component forces; the pin shaft and the sleeve of the hinge bear a large specific pressure, and they will move relative to each other, which will cause the wear of the hinge and make the actual The pitch becomes longer and the sag increases, resulting in poor meshing and chain vibration, resulting in greater friction and component force; the acute angle formed by the left and right flat fork tubes causes the full chain cover to be uneven or the half chain cover to be asymmetrical and asymmetrical. Affects the appearance, not clean and tidy

Abstract

A resistance-drive transmissive bicycle with small, light and neat toothed chains structurally comprises a toothed chain box arranged between a middle shaft and a rear shaft and a left fork plate, wherein the middle shaft, a II shaft, a III shaft and the rear shaft are arranged in the toothed chain box, a driving gear is arranged on the middle shaft, a duplex gear is arranged on the II shaft, a duplex combination consisting of a gear and a chain wheel is arranged on the III shaft, a chain flywheel is arranged on the rear shaft, and a transmission assembly is formed by the gear and the chain wheel. A left bearing crank, a right bearing crank, a left axle wheel and a right axle wheel are arranged on the middle shaft besides the driving gear, and are driven through resistance spots and force bearing grooves to rotate.

Description

technical field [0001] The invention relates to a power transmission mechanism of a bicycle, in particular to the combination of gear and sprocket transmission and the application of leverage. Background technique [0002] The traditional bicycle is a chain transmission, and the transmission mechanism composed of a large chainring, a chain, and a chain flywheel has many disadvantages: because the chain wheel of the chain transmission is large at the front and small at the rear, the pulling direction of the chain is not parallel to the direction of motion, resulting in force components ;The sagging of the chain will cause the force between the links and the direction of movement and the angle to be different to produce component forces; the pin shaft and the sleeve of the hinge bear a large specific pressure, and they will move relative to each other, which will cause the wear of the hinge and make the actual The pitch becomes longer and the sag increases, resulting in poor m...
