EXCERPT:
Drive Axle
The drive axle consists of differential, final reduction gear assembly, wet type hydraulic disk brake unit, and axle shafts to which wheels are attached.
The power from drive unit is transmitted through the drive shafts to front and rear drive axles. The power is then transmitted to differential where it is divided into right and left axle shafts to final reduction gear assembly on each shaft end, thus driving the wheels.
The wet type hydraulic disk brake unit is installed in front of final reduction gear assembly and serves as a service brake.
Axle Mount
The front axle is bolted directly to front frame.
The rear axle is supported by the trunnion method in which axle supports are installed across the rear axle and bolted to rear frame. Consequently, the rear axle is cradled up and down around the center line of differential according to ground condition the loader travels. The trunnion mounted drive axle helps improve operator comfort because loaders with a trunnion mounted drive axle jolt less than those with the conventional cradle supported drive axle, when they travel on bad ground conditions.
