ABSTRACT:
A work vehicle includes lefthand and righthand suspension mechanisms individually having an elastomeric belt entrained about a plurality of roller wheels and a fron wheel assembly, with the front wheel assembly having inboard and outboard side portions connected together by a shaft and being mounted on a pivotable support member. The subject wet disc brake mechanism includes an annular housing assembly supporting the wheel shaft, a brake hub connected to the shaft, a brake assembly having a plurality of interleaved plates disposed within the housing assembly, and a plurality of internal passages for the ingress of a cooling fluid radially inwardly of the plates, the egress of the fluid radially outwardly of a collecting chamber defined within the housing assembly, and for delivering a control fluid to a service brake piston and a parking brake piston arranged in a compact overlapping manner. Moreover first and second pluralities of radial openings through the brake hub and housing assembly respectively promote radial cooling of the plates at a minimal back pressure.
