A hub for a wheel having a built-in brake assembly and suitable for use in industrial vehicles, agricultural machinery, civil engineering plant and materials handling plant comprises a stub axle on which is rotatably mounted a hollow body forming a casing to contain a lubricating and cooling fluid.

A hub for a wheel having a built-in brake assembly and suitable for use in industrial vehicles, agricultural machinery, civil engineering plant and materials handling plant comprises a stub axle on which is rotatably mounted a hollow body forming a casing to contain a lubricating and cooling fluid. A brake assembly with fixed and rotatable disks is disposed within the hollow body inside an annulus constrained to rotate with the stub axle. Associated with the annulus is a scooping device adapted to provide communication between the interior of the annulus and the annular space between the annulus and the hollow body, for improved supply of the lubricating and cooling fluid to the interior of the annulus.

A hub for a wheel, said hub having a built-in brake assembly and comprising a fixed support sleeve, a hollow body which is mounted rotatably on said sleeve and constitutes a casing adapted to contain a hydraulic lubrication and cooling fluid, an annulus disposed within said hollow body so as to leave an annular space between said annulus and said body, said brake assembly being within said annulus and featuring at least one rotary disk which is adapted to be constrained to rotate with an associated wheel shaft, and scooping means associated with said annulus for force feeding the hydraulic fluid radially inwardly from said annular space between said annulus and said hollow body into the interior of said annulus in order to cool and lubricate the brake disk therein.
