The GURIS development center at the Parsan near Istanbul, the first e-axle is now being developed in collaboration with AVL, following the successful development of truck front axles and planetary axles. The forging plant, along with machining and assembly facilities for the axles, is located at the Parsan site. The required castings are supplied by the Döktas foundry, a GURIS Group company, while the necessary steels are provided by Asil Celik steelworks, also part of the GURIS Group.

With its Technology Center for Commercial Vehicles in Steyr, Austria, AVL is one of the world's leading engineering service providers. The primary goal of developing the e-axle with AVL was to meet diverse customer requirements and provide an optimized drive solution for various applications.

The AVL e-axle solution offers 400 kW of continuous power and 540 kW of peak power, sufficient to meet all typical requirements for long-haul applications. The key innovation of this new system is its multi-speed transmission, which allows for shifting without interrupting torque and eliminates the need for wet clutches, typically causing high drag losses. Additionally, it offers various driving modes that enable shifting the operating points of the electric motors to areas of optimal efficiency. This feature enhances system efficiency and ensures smooth shifting.

Rolf Döbereiner, Product Line Manager at AVL, stated, “To meet market requirements of electric-driven HD trucks, the e-axle developed by AVL and GURIS Industrial Group offers a compact and efficient solution for long-haul trucks without jeopardizing total cost of ownership. The e-axle modular kit provides solutions for customers worldwide, tailored to their respective HD applications.”

Combining AVL's development expertise with the manufacturing capabilities of GURIS companies Parsan and Döktas, the axle has been optimized for series production to ensure high quality. The main development priorities included a flexible, scalable, and modular design, effective packaging within the chassis, maximum efficiency, and minimal weight.

The inverter is already mounted on the axle, and an EACU (E-Axle Control Unit) can be provided for the vehicle's software architecture if required by the customer.
