Title:
SPUR GEAR FINAL DRIVE WITH INTEGRATED BRAKES
Document Type and Number:
WIPO Patent Application WO/2012/125778
Kind Code:
A3
Abstract:
An improved final drive is disclosed. The axle includes a double reduction gearbox for off-road machines, which, unlike currently available double reduction gearboxes, contains no planetary gear sets. The improved drive axle contains spur gears having pockets adapted to contain brake disc packs. The pockets may permit utilization of a plurality of brake packs within the gearbox without requiring additional space or enlargement of the gearbox housing. Use of spur gears may thus enable use of fewer gear parts, while use of multiple brake packs may enhance final drive brake capacity, improve longevity of the brake packs, and lengthen brake servicing cycles.
