In order to create a smooth and continuous motion, the spring performance was matched with a damper to ensure the consol travelled smoothly, even when subject to vibrations due to vehicle movement. The spool was manufactured from a specific polymer and designed to align with the geometry of the spring and mating carrier components - which enabled low friction when sliding the assembled parts without stick-slip, causing squeaking. Ultimately, the spring and spool assembly translates rotational torque into a linear sliding motion.
TR teams from the USA and Sweden worked alongside global manufacturers to solve this engineering challenge. "We did extensive research and had many interactions with experts in the manufacturing field. These relationships are so important. To have transparency around the challenges and capabilities - this open communication helps us find the right solution," explains Patrik. Despite the initial challenge, TR was able to provide a full-service provision, offering extensive technical expertise from initial design and prototyping of the product to full serial production.
Patrik adds: "One of our greatest strengths is the breadth and diversity of our manufacturing capabilities. Thanks to our supplier relationships and our strong understanding of the manufacturing technologies - this helps us visualise how the product should be made."
Through collaboration with its customers, as well as utilising its own global teams, TR has created a custom spring and spool system specially tailored to its customer's requirements.
