Allison Transmission has unveiled its new ABE Series, the first e-axle advanced ultra-low floor electric bus powertrain system in the market. The company says these e-axles are among the world’s most powerful and compact fully-integrated axles for the transit bus market.
Allison’s Chief Technology Officer, Michael Foster, says: “The product integrates dual electric motors, a single- or multi-speed gearbox depending on e-axle model, oil coolers, pumps and power electronics into a bolt-in system that replaces the entire traditional powertrain within the existing frame. It meets the power and space demands of the transit bus industry, including heavy double-decker, articulated and three-door buses.
“The Allison ABE Series can operate without restrictions at regular highway speeds and on all required grades. It can handle 100% torque in regenerative braking. With an axle rating up to 13 tonnes, we believe the system provides more power and torque than any other e-powertrain system in its class.”
