Abstract

The invention discloses a scooter hub internally provided with a drive speed transmission. The scooter hub is characterized in that a hub is hollowly arranged, and the hub is internally provided with the drive speed transmission, wherein the drive speed transmission comprises a drive gear and a pair of driven gears, each driven gear is provided with a ratchet wheel, one side of the drive gear is meshed with the ratchet wheel of one driven gear, the other side of the drive gear is meshed with the ratchet wheel of the other driven gear through an intermediate gear, the inner circumference of the rim of the hub is provided with meshing teeth, the driven gears are meshed with the meshing teeth of the inner circumference of the rim, and the drive gear is in meshing connection with a driving handle. According to the scooter hub disclosed by the invention, the drive speed transmission is integrated with the hub and works to drive the hub to drive, so that the scooter hub has the advantages that the structure is compact, the assembly precision is high, the floor space is small, and the higher structure space optimization is realized; and in addition, the transmission of inner gears of the drive speed transmission is synchronous with the drive of the hub, so as to ensure that the instant transmission ratio is constant, the smoothness is high, the transmit movement is exact and reliable, the transmitted power is higher, the speed range is larger, larger transmission ratio is realized, and the transmission efficiency is high.

Description

technical field [0001] The invention relates to accessories of a scooter, in particular to a scooter hub with a driving transmission device inside. Background technique [0002] Currently, the scooter market is popular. The more common electric scooters have an electric hub, which is composed of a motor wrapped in the hub shell, and the motor drives the wheel to rotate. The electric hub is large in size, too heavy, and consumes power Large, and the sealing effect is poor, and the motor will be easily burned after entering the water, which is not conducive to safe driving. [0003] There are also some manual power-assisted scooters equipped with a simple transmission device, including a chain and a set of drive transmission device. The rotation of the wheel drives the flywheel to rotate, and then drives the axle to rotate to realize the forward movement of the vehicle. However, this kind of transmission device has a large volume and takes up a lot of space; the assembly is ...
