Abstract

A motorized wheel assembly is provided herein. The motorized wheel assembly comprises an in-hub motor comprising a stator and a rotor. A shaft is connected to the stator of the in-hub motor. The motorized wheel assembly further comprises a hub, attached to and configured to rotate with the rotor. The hub is disposed about the shaft and the in-hub brake system. The wheel assembly further includes a tire disposed about the hub. The motorized wheel assembly further comprise an in-hub brake system positioned about the shaft. The in-hub brake system comprises a biasing system, an actuator plate, a brake plate, and a brake pad system. The biasing system is configured to bias the actuator plate to the engaged position to cause the brake pad system to apply a force to the brake plate to prevent rotation of the hub and the tire.
