Word forms: (regular plural) beam axles
(Automotive engineering: Vehicle components, Engine, transmission, and exhaust)
This kind of hub is used mainly on larger vehicles, where a beam axle is fitted instead of independent suspension. This model features a multi-link beam axle at the back to help counter rear-end instability. The trucks are a refined version of the five-link coil-spring suspension with beam axle used on the previous heavy-duty trucks.
