Title:
WHEELS AND BRAKES FOR VEHICLES
Document Type and Number:
WIPO Patent Application WO1998003354
Kind Code:
A3
Abstract:
A braking system for an automotive vehicle is provided which comprises, in combination, a wheel having a specifically-defined wheel rim for mounting a tire thereon, and a specifically-defined disc carrying the wheel rim for mounting the wheel upon a wheel support of the automotive vehicle. A cylindrical support is secured to the wheel. Radially-inwardly facing arcuate brake lining structures are secured to the cylindrical support. Brake shoes are mounted upon a non-rotatable part of the automotive vehicle in spaced positions around the rotational axis of the wheel support. A pressurized-fluid operating system of a specifically-defined structure is provided for moving the brake shoes in a braking action radially-outwardly from inactive positions towards, and frictionally-engaging, the brake lining structures, and for returning the brake shoes radially-inwardly to the inactive positions upon termination of said braking action. Primary additional structure is also provided for effecting movement of the brake shoes to further inactive positions by drawing pressurized-fluid from the braking system.
