To help meet customer demands for operational flexibility, ArvinMeritor, Inc. recently introduced its new global hub reduction axle family of single and tandem rear axles for the heavy-haul, construction, refuse, logging, concrete, mining and vocational markets.
The axles – offered first to the Asian market and available in North America in early summer – offer a wide ratio range to meet the needs of virtually any on- or off-highway application, as well as a host of suspension adaptations and brake offerings.
The new global family of hub-reduction axles offers ratios ranging from a fast 3.61:1 to 7.21:1 to meet higher road speed requirements, the company said. These robustly engineered axles offer technology that’s proven in Europe for highway and vocational applications requiring higher gross combination weight and export markets such as South America and South Africa.
The company said the advantages come from several key features of the new fully dressed axle assembly, including: fabricated housing for a lightweight, high-capacity design in both single and tandem configurations and can support a variety of suspension requirements; weight savings up to 600 lbs. depending on model selection; streamlined carrier design for increased ground clearance for improved mobility; proven four-planet wheel-end hub-reduction gearing for higher capacity ratings and superior performance. The single axle is rated at 26,000-35,000 lbs. GAWR, and the tandem is rated at 52,000-70,000 lbs. GAWR; needle-bearing design throughout the interaxle differential provides spinout protection and eliminates the need for a lube pump; driver-controlled differential locks are standard in both the forward and rear axle for increased traction when needed; optimized driveline angles to reduce harsh driveline angle vibrations for longer axle life.
When combined with the Meritor MX-160 front-drive steer axle, the new hub-reduction axle – in either single or tandem configuration – provides maximum mobility in any operating condition for an advanced-engineering all-wheel-drive solution, the company said.
