Allison unveils electric propulsion solution for low-floor buses

 

2 min to read


At the Advanced Clean Technology Expo in Long Beach, California, Allison Transmission introduced the new ABE Series, the first e-axle advanced ultra-low floor electric bus powertrain system in the market. The ABE Series e-axles are one of the world’s most powerful and compact fully integrated electric axles for the transit bus market.

The ABE Series 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 allowable grades. The system can handle 100% torque in regenerative braking. With an axle rating up to 28,660 pounds, the system provides more power and torque than any other e-powertrain system in its class on the market. With a dual motor, it has continuous axle output power of 536 horsepower and peak output power of 738 horsepower. A single speed e-axle option also is available. Its proprietary cooling allows for industry-best continuous motor power and allows the vehicle to run closer to peak power for longer durations.

The bolt-in ABE Series fits existing bus frames and suspensions, creating more space for battery packs and other critical electric vehicle components.

An attractive feature for bus manufacturers is the system’s compact design. The bolt-in ABE Series fits existing bus frames and suspensions, creating more space for battery packs and other critical electric vehicle components. The standard system is configured for a 28-inch walk through, but has an optional 39-inch configuration. This makes the system applicable for 40-foot low-floor city and double-decker buses, 60-foot articulated buses, and three-door buses.
