Meritor is supporting severe-duty applications with the new MX-610 front drive axle and MZ-610 tridem rear axle. The MZ-610 tridem offers wide-ranging axle ratings and a high ground clearance as well as a gross axle weight rating of 60 tons […]
Meritor’s P600 planetary axles are now available with optional five-planet wheel-ends and can now be configured for use with central tire inflation systems. The optional five-planet wheel ends allow a 20% higher gross combined axle weight rating (GCWR) when compared […]
TORONTO, Ont. — We’re at the dawn of a new era in the propulsion of heavy trucks. Electric powertrains are opening new packaging and integration possibilities, including driven axles. Traditional transmissions, driveshafts, power dividers or differentials are no longer required.
Peterbilt vocational trucks can now be spec’d with the new PACCAR 20,000- and 22,000-pound wide track steer axles designed for applications such as refuse, construction and heavy-haul.
First revealed at the Mid-America Trucking Show in March, Dana’s Dual Range Disconnect drive axle system offers the fuel savings benefit of a downsped 6×2 drivetrain and the performance benefits of conventional 6×4 setup with a mid-range axle ratio. The key word here is disconnect. While running at speeds up to about 54 mph, the system functions as a 6×4 with torque going to all four wheels for optimum traction. It also runs at a 3.10:1 ratio for better performance and startability. Above 54 mph, the interaxle driveshaft disengages, leaving the driving to only the forward drive axle. Interestingly, the axle ratio of the forward axle is 2.26:1, which lowers engine rpm and in effect creates a downsped drive train. The benefit, of course, is better fuel economy resulting from a 300-400 rpm drop in engine speed.
Volvo Trucks has put a new spin on an old powertrain management strategy; by locking out top gear on its I-Shift overdrive transmission, drivers can pull loads efficiently in 11th gear (direct drive) and still get the performance they want. When running empty, sensors in the transmission and the suspension sense the lower weight and unlock 12th gear, which is overdrive. The truck can cruise home in at a very low engine speed at a higher road speed.
This video explains how Adaptive Gearing works and features more excerpts from an interview with Gene Brice, co-owner of Idaho Milk Transport. Adaptive Gearing is ideally suited to tank fleets that run about half their miles empty, and when you hear Brice’s fuel economy with this system, you’ll be asking if it can work for you too.
And don’t forget to check out our Focus On report on Volvo’s Adaptive Loading system to see what it has to offer.
When Volvo announced its new Adaptive Loading technology at the Mid-America Trucking Show in March, much was made of its seamless, no-driver-input-required ability to switch between 6×2 and 6×4 axle configurations.
That was then.
Five months later, after having about 200 trucks equipped with Adaptive Loading in use across North America, fleets that employ the technology are reporting a wide variety of other welcome results, including improved fuel mileage; much faster drop-and-hook times; much longer tire wear; greater payload because the system itself weighs about 300 lb less than a standard 6×4 setup; increased traction on wet pavement; easier take offs on snow and ice; and even improved driver retention.
HAGERSTOWN, MD — Mack Trucks this week inaugurated its new axle line at its Hagerstown, MD facility, with a look to its past. The new line, where Mack powertrain components have been assembled since 1961, is part of a US$30 million investment, which brought assembly of all Mack heavy-duty drive axles and machining of Mack carrier housings to the plant.
