In the single-reduction rear axle, power is transmitted from the propeller shaft to the driven wheels in one single stage. This type of rear axle is lightweight and has very small internal power losses, which in turn helps minimise fuel consumption.
Demanding conditions and heavy loads are part of everyday life for many Volvo truck drivers. With a Volvo FL equipped with a rear axle featuring a hub reduction you bring extra power to your truck. The ratio reduction takes place in two steps, so the burden on the driveshafts and final drive is lower. This promotes good operating reliability even at high power outputs and high speeds.
