SAF-HOLLAND, at the Technology and Maintenance Council's 2022 Annual Meeting & Transportation Technology Exhibition in Orlando Sunday, announced it has begun market and product development phase of its trailer electric axles on real-world transportation applications for North America.

Since first presented at the 2018 IAA Commercial Vehicles show in Hanover, Germany, electric axles from SAF-HOLLAND have gone through further development steps and the SAF TRAKr (or recuperative axle) is currently undergoing testing around the world. The SAF TRAKr uses a high-voltage generator module for electric power regeneration to lower the emissions and fuel consumption of the overall vehicle. SAF-HOLLAND e- axles have been undergoing rigorous testing in real-world operation in Europe and South Africa.

That the recuperative axle recharges the battery as it drives, it comes with more flexibility and range than a shore power model and allows the system to use a smaller battery pack, said Bill Hicks, product manager, Axle/Suspension Systems–Americas,

The modular trailer e-axle system allows for easy installation by trailer manufacturers and uses standard assembly line procedures. The TRAKr e-axle will be available in the future on both SAF mechanical and air suspension tandem axle slider systems for reefer trailer applications. The e-axle is is connected to a battery pack and its operation is controlled by a control system.

The electrical generator drive unit does not have to be removed when servicing the wheel ends. Wheel-end componentry, with the exclusion of the proprietary hub assemblies, remains unchanged for easy serviceability. Wear parts such as brake pads, calipers and brake disc rotors are standard SAF-HOLLAND components to ensure and simplify spare parts supply and servicing.
