Axles

Heavy-duty Volvo Axles The Volvo-designed axles on the A25D and A30D are matched to the other components in the drivetrain for optimal performance. The axles are designed for use of optional wheel equipment recommended by Volvo, such as 65 profile tires. Fully-floating drive shafts All working stresses are absorbed by the rigid cast axle housing. The drive shafts transfer only the torque, for maximum durability. Heavy-duty hub reductions Proper gearing at the wheels reduces stress on the uni- versal joints and drive shafts.This means that the dimen- sions and weight of these components can be minimized. The hub reductions are easily accessed for service and repair without removing the wheels.

Differentials Each drive axle has a differential that permits the wheels to rotate at different speeds, which is essential for good cornering characteristics. When locked, off-road performance improves and rimpull can be fully utilized on the wheel with the best traction.

Volvo 100% differential lock All axles have 100% lockable differential locks of a dog- clutch design that physically lock the drive shafts together. The operator controls the differential locks that can be engaged and disengaged on the move.

Advantages • Heavy-duty axle housings for long service life. • Fully-floating drive shafts increase reliability. • Heavy-duty hub reductions ensure long service life for other drivetrain components. • 100% lockable differentials give superior off-road mobility performance. • Differential locks can be engaged and disengaged on the move.
