Sammanfattning
Addressing the global urgency to reduce climate impact, Volvo Group is committed
to reducing vehicle emissions by 40% by 2030. Trucks are essential to modern transportation,
highlighting the importance of developing sustainable truck and trailer
technologies. Sweden’s new High Capacity Transport (HCT) regulation, aimed at
lowering carbon emissions, supports this initiative. Furthermore, Volvo GTT is exploring
new technologies including the E-trailer, an electric semi-trailer that possibly
reduces fuel consumption by 5-20% compared to traditional models.
The purpose of this project is to develop and optimize the next generation of the
E-trailer. This includes determining the necessary requirements for the design and
development of the chassis utilizing existing Volvo components. Additionally, Hammar
Maskin AB, assigned with constructing the prototype, must modify its chassis
to integrate effectively with the existing components from Volvo GTT.
The methodology employed relies on a design thinking approach, structured into
four interactive phases. The initial phase, "theoretical framework," involves collecting
comprehensive information about the E-trailer and gaining insights into related
fields. The second phase, "identification," focuses on assessing current market offerings
and understanding customer requirements. The third phase, "development,"
encompasses the entire development process, detailing the tools and strategies used.
The final phase, "finalization," thoroughly presents the developed concept, highlighting
its specifications and features.
The final design of the E-trailer features a unique semi-trailer with a single chassis
that integrates dimensions from Hammar Maskin AB at the front, near the gooseneck,
and Volvo GTT’s specifications towards the rear, creating a chassis that curves
and widens at the back. The chassis has an I-shaped cross-section with specific cutouts
to accommodate various components. Modifications have been made to the
mounting of specific components, while others have been replaced to optimize the
trailer’s functionality and performance.
In conclusion, the project successfully developed an E-trailer that meets customer
requirements. Hammar Maskin AB’s chassis was able to adapt to Volvo GTT’s
components, making it feasible to develop a single chassis. Recommendations include
analyzing the placement of certain components and calculating the weight.
Additionally, for future generations, simplifying the chassis to make it suitable for
mass production.
