Abstract

The invention discloses a wheel assembly of a baby stroller and the baby stroller. The wheel assembly comprises an axle and a hub. The hub is arranged on the axle in a sleeving mode and can rotate around the axle. The wheel assembly further comprises a driving mechanism. A space for installing the driving mechanism is formed between the axle and the hub. The driving mechanism is arranged in the space, and comprises a motor arranged on the axle, an outer gear driven by the motor rotate and an inner gear meshed with the outer gear. The inner gear is fixedly connected to the hub or integrally formed together with the hub. The whole driving mechanism is arranged in the hub of the wheel assembly, so the wheel assembly is compact in structure and has a dustproof and waterproof function for the driving mechanism. A speed reduction transmission mechanism is composed of the inner gear and the outer gear, the transmission ratio can be increased, the torque of the hub is increased, and sufficientdriving force can be provided for wheels by means of the low-power motor.

Description
