assemble the final spring and spool product. This saw a collection of experts come together throughout the project to ensure its success. “Leveraging our experience and
global supplier network, we designed a solution that not only met their precise needs but also provided enhanced functionality and durability,” Ringdahl explains. The mechanism requires a
suitable damper to match the spring performance to enable the smooth and continuous motion of the central control mechanism, both in a stationary vehicle or when in operation over uneven terrain. To achieve this, TR developed a spring and spool assembly which translates linear motion into rotation. The client also requested the spring and spool to operate silently. Using a high-lubricity plastic
achieved a low-friction product, making use easier and reducing noise. Customers experienced and even and easy pull due to the aligned geometry of the spool and spring. TR used a specific polymer to produce the spool, ensuring low static and dynamic sliding friction against mating surfaces. To help keep costs down and speed
up installation time, the size of the spool was reduced, which required less raw material and simplified the installation process. The product met the demands of the client’s central console mechanism whilst being reliable, cost-efficient and functionally smooth.

“This approach means our customer
benefits from a reliable, high- performance component, supporting their commitment to quality and innovation,” Ringdahl adds. “Growing with our customers to create functional, forward-thinking solutions is what drives our teams at TR every day.”
IMPROVING EVS MATTERS Introducing new technologies to EVs can have a far greater impact than merely just improving a user’s enjoyment. The world is currently in a race against time to blunt the blade of climate change, and innovations such as EVs can aid in this global mission. The uptake of EVs is essential to reducing the impacts of climate change, especially in densely populated areas. Research from the European Union
has found EVs produce significantly less greenhouse gas emissions than combustion-driven cars over the
course of their lifetime. Hand in hand with curbing emissions, EVs have a neutral impact on air quality, an increasingly vital topic in urban areas. Car manufacturers have been
heavily incentivised to increase their focus on the manufacturing and production of EVs. Firstly, by market shifts as diesel sales in the UK have fallen by a fifth whilst petrol car sales have fallen by 14% according to recent data published by the Society of Motor Manufacturers and Traders (SMMT). And secondly, by the UK government’s policy to ban the sale of new petrol and diesel cars by 2035. Similar action is being taken by many other governments around the world. As 2024 comes to an end, reports
indicate an increase of 18.1% in sales of EVs, an improvement on the 15.6% rise at the same point in 2023. Advancements in EVs, whether that be vehicle mechanics or user-focused elements, are essential to continue to accelerate the transition to electric.
