Abstract:

A brake and wheel assembly for vehicles having small diameter wheels and heavy axle loading requiring high capacity braking is disclosed. An axle extension shaft cantilevered transversely on a vehicle frame mounts rotatably a dual wheel hub which also serves as a brake rotor in coaction with a pair of wide brake shoes. A mounting unit for brake mechanism including a rigid backbone member is cantilevered from the vehicle frame across the axis of the axle extension shaft and brake rotor. The backbone member locates and supports front and rear brake cylinder bodies and associated anchor pins for the brake shoes and also supports a brake shoe upper guide. Brake shoe hold-down bases and other components are attached to a back plate of the brake mechanism mounting unit which also includes a side cover. A mechanical parking and emergency brake is included in the assembly along with required brake adjustment features. Compactness, ruggedness, ease of assembling and servicing and the use of standard automotive-type wheels are primary features.
