摘要:
A speed limited wheel includes a wheel main body defining a cavity, a urethane wheel outer overmolded to the cavity, a brake hub and a plurality of brake elements. The brake hub is disposed in the cavity and includes a cylindrical flange. The wheel main body is rotatable relative to the brake hub about a wheel rotational axis. The plurality of brake elements is disposed in the cavity and is circumferentially surrounded by the cylindrical flange of the brake hub. Each brake element is pivotally mounted to the wheel main body for pivoting between a first position spaced apart from a cylindrical flange of the brake hub and a second position engaging the cylindrical flange of the brake hub for generating friction to reduce a rotational speed of the wheel. The speed limited wheel may be a caster.
