Speed limited wheel
09776602 · 2017-10-03 · ·

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.

TONE RING WITH PROTECTIVE FILLER
20180290637 · 2018-10-11 ·

A tone ring for a heavy-duty vehicle anti-lock braking system (ABS) that includes a filler disposed within spaces or notches between teeth formed in the tone ring. The filler is formed of a material that does not interfere with the ability of an ABS sensor to sense the teeth. In one embodiment, the filler includes a plurality of protrusions disposed within the spaces formed between the teeth. The plurality of protrusions are integrally formed with a base that extends circumferentially around the side of the tone ring opposite the ABS sensor. In another embodiment, the filler includes a plurality of fillings disposed within notches formed between the teeth. The filler prevents road debris and/or contaminants from damaging the tone ring teeth and damaging and/or misaligning the ABS sensor. A thin coating can extend over the tone ring teeth and the plurality of protrusions or fillings to encapsulate the teeth.
