· ZF’s electrified trailer concept on-show at IAA Transportation under its new name, TrailTrax
· TrailTrax can generate energy and CO2 reductions of up to 16 percent by recuperation; with up to 40 percent CO2 reductions achieved by Plug-In charging
· Leading trailer manufacturers also presenting their electrified trailer concepts at IAA Transportation 2024, adopting ZF’s TrailTrax technologies
Hanover (Germany). As trucks become more fuel-efficient, trailers are emerging as a key technology area where further carbon emission reductions can be made. ZF’s electric trailer concept, on show at the IAA Transportation 2024 under the new brand name TrailTrax, integrates its in-house developed 210kW AxTrax 2 e-Axle, trailer EBS, and battery system box into a trailer. Leading trailer manufacturers, including Kässbohrer and Krone, as well as trailer running gear and axle supplier BPW, are adopting ZF’s TrailTrax technologies. Kässbohrer will present an electrified trailer with TrailTrax integration at this year’s IAA, highlighting the growing interest in ZF’s electrified trailer system solution.
ZF’s TrailTrax system provides driving propulsion as well as brake energy recuperation, generating up to 16 percent in energy and CO2 savings when combined with an ICE powered truck. The system can also reduce CO2 emissions by up to 40 percent with plug-in charging. Integral to the system is ZF’s electrified axle, the AxTrax 2, from ZF´s eDrive platform. By integrating it into a trailer running gear in combination with other associated system components, it effectively converts an ICE truck-trailer combination into a hybrid, while extending the range of an electric vehicle.
“TrailTrax technologies offer significant potential to reduce operational costs and CO2 emissions in road freight transportation. Energy losses, including brake friction, air drag, and rolling resistance, are major causes of fuel inefficiency, but with our TrailTrax concept, we can make a big difference,” says Dr. Bernd Meurer, who is responsible for the TrailTrax program at ZF.
“Successfully managing this transformative technology will require the combined efforts of all industry players. We are pleased to see our technologies are gaining traction among leading trailer manufacturers as well as fleet operators across the globe, who recognize the potential that TrailTrax can bring towards achieving sustainability goals.”
At the IAA Transportation 2024, leading trailer manufacturers are presenting their electrified trailers equipped with TrailTrax technologies. ZF is collaborating closely with leading trailer manufacturer Kässbohrer to develop its electrified trailer solution. Kässbohrer’s electrified curtainsider, which features the system integration of TrailTrax, will be on show at the IAA.
Trailer manufacturer Krone is also presenting its solution, highlighting the growing interest in ZF’s TrailTrax technologies. ZF’s outdoor booth will feature a Krone reefer trailer with the TrailTrax system installed. The electrified Krone trailer, capable of reducing CO2 emissions by up to 40 percent, demonstrates the potential efficiency gains achievable with ZF TrailTrax technologies.
Ms. İffet Turken, Executive Board Member of Kässbohrer said: “We highlight the importance of a wide ecosystem of innovation and partnerships to advance the trailer industry towards sustainability. We are proud to collaborate with ZF in the safe and efficient integration of their electrified axle, EBS systems, and battery pack into our trailers.
Our prototyping is carried out at our state-of-the-art European R&D center with the goal to present customers an electrified trailer that both delivers on operational ease and efficiency and can be seamlessly integrated into their regular business operations while helping to contribute to CO2 reductions.”
Field tests of Kässbohrer trailers are expected to commence from 2025 across Europe under the ZEFES (Zero Emissions flexible vehicle platforms with modular powertrains serving the long-haul Freight Eco System) project funded by EU.
Markus Stegen, Managing Director Product Management and New Markets at Krone Trailer, explains: “At Krone, we believe in the importance of electrification in the context of the transformation of the transport sector and work with our industry partners to harness the potential of electrified trailers.”
Markus Schell, personally liable managing partner of BPW said: “Every trailer needs a running gear, suspension and braking technology that can be trusted. With our axles for 7.5t trucks and the generator axles for reefers, we already have a lot of experience regarding the integration of electric drives. It therefore makes perfect sense that ZF, with expertise in drivelines, cooperates with BPW to offer a robust and highly engineered running gear solution with the AxTrax 2 axle for recuperation and traction support for semitrailers that can be easily assembled by trailer builders and is fully trusted by the fleets.”
ZF’s TrailTrax solution is designed to meet future global standards and comply with national and regional regulations. The first electric trailers are expected to enter operation after the relevant regulatory and safety processes have been completed.
