To support the development of its hydrogen solutions, Hyliko relies on Dana TM4, a leading industrial player in transmission and propulsion systems for heavy vehicles. This partnership is based on a shared vision: to offer technologies adapted to the real-world constraints of the field.
The systems supplied by Dana TM4 are integrated into the heart of Hyliko hydrogen trucks to ensure power transmission to the wheels under demanding operating conditions. They are designed to meet the demands of specific applications: long-distance transport, energy-intensive equipment such as tippers or cranes, and repeated starts, such as those encountered on construction sites.
This robustness guarantees:
- Long-term mechanical durability
- Stability of performance
- Reduced downtime due to premature component wear
Integrating transmission components into a retrofitted vehicle requires a specific approach. Unlike a new vehicle, retrofitting necessitates working with an existing chassis and specific architectural constraints.
Dana TM4’s expertise allows for the adaptation of transmission systems to these constraints while respecting safety, compatibility, and maintainability requirements.
This adaptability is a key lever for industrializing hydrogen retrofitting on a heavy-duty transport scale.
A partnership based on industrial expertise
By integrating transmission systems designed for heavy-duty commercial vehicles, Hyliko ensures that its hydrogen trucks meet the same usage standards as conventional vehicles. The transition to zero-emission road transport is accompanied by maintained performance and reliability.
Damien Gremillard, Product Manager at Dana TM4, emphasizes the importance of close collaboration between integrator and supplier. This approach secures the transition from innovation to commercial operation.
The partnership between Hyliko and Dana is part of a long-term vision. It provides a robust technological foundation to support the future development of hydrogen trucks, based on a logic of continuous improvement of the deployed solutions.
