Abstract

The embodiment of the invention discloses a split type driving and speed changing device and an electric power-assisted bicycle, and relates to the technical field of bicycles. The split type drivingand speed changing device comprises a speed changing device. The speed changing device comprises an auxiliary driving unit, a first transmission mechanism, a chain wheel and a crankshaft, and the first transmission mechanism comprises a first planet carrier, a first planet wheel, a first sun wheel and a first transmission wheel; the outer side of the first transmission wheel is fixedly connected with the chain wheel; the first planet carrier is arranged on one side of the first transmission wheel, and the first planet carrier is fixedly connected with the crankshaft; the first planet wheel isarranged on the first planet carrier and engaged with the first sun wheel and an inner gear ring of the first transmission wheel; and the auxiliary driving unit is connected with the first sun gear. According to the split type driving and speed changing device, continuous speed changing can be achieved, and a pause feeling is not generated.

Description

technical field [0001] The invention relates to the technical field of bicycles, in particular to a split drive and speed change device and an electric assist bicycle. Background technique [0002] An electric power-assisted bicycle is made by adding a power assist system on the basis of a bicycle. Its purpose is to make cycling easier. [0003] According to the installation position of the power assist system in the electric assist bicycle, it is divided into a front motor system, a middle motor system and a rear motor system. The front motor system is installed in the front hub to directly drive the front wheels. The mid-mounted motor system connects directly to the crank and gears of the bike's bottom bracket. The rear motor system is installed in the rear hub to directly drive the rear wheels. [0004] The power response generated by the mid-mounted motor system is fast, the riding experience is good, and it is more in line with European and American riding styles. I...
