Abstract

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.

IPC Classes  ?

• F16D 59/00 - Self-acting brakes, e.g. coming into operation at a predetermined speed
• B60T 1/06 - Arrangements of braking elements, i.e. of those parts where braking effect occurs acting by retarding wheels acting otherwise than on tread, e.g. employing rim, drum, disc, or transmission
• B60B 5/02 - Wheels, spokes, disc bodies, rims, hubs, wholly or predominantly made of non-metallic material made of synthetic material
• B60B 27/02 - Hubs adapted to be rotatably arranged on axle
• B60B 33/00 - Castors in general
• B60T 8/54 - Arrangements for adjusting wheel-braking force to meet varying vehicular or ground-surface conditions, e.g. limiting or varying distribution of braking force responsive to a speed condition, e.g. acceleration or deceleration by mechanical means
• B60T 7/12 - Brake-action initiating means for initiation not subject to will of driver or passenger
• F16D 51/32 - Brakes with outwardly-movable braking members co-operating with the inner surface of a drum or the like shaped as brake-shoes pivoted on a fixed or nearly-fixed axis with three or more brake-shoes
• F16D 51/56 - Self-tightening brakes with pivoted brake-shoes with three or more brake-shoes, at least two of them being linked or directly interacting mechanically actuated
• F16D 65/08 - Bands, shoes or pads; Pivots or supporting members therefor for internally-engaging brakes
• F16D 65/10 - Drums for externally- or internally-engaging brakes
• F16D 121/14 - Mechanical
