In automotive engineering, every component plays a critical role in ensuring vehicle performance and reliability. This case study outlines how Hi-Tech Seals provided an effective solution to Formule ETS’ issue with elastomer seals that could not withstand the operational demands of their machinery.
Customer Profile
The customer is Formule ETS, a team of engineering students from the École de technologie supérieure in Montreal. For over 36 years, Formule ETS has been designing and building racing prototypes with a performance-focused approach. Their prototypes have been recognized internationally as complex and accomplished vehicles, and the team itself as forward-thinking that pushes the limits of performance to a professional standard. They compete internationally every year at FSAE and Formula Student competitions.
Application
The sealing ring is located between the rotor and the motor housing of their new electric prototype platform. The seal isolates the lubricant used in the transmission from the internal components of the motor. This vehicle model required a more rigorous design and manufacturing process to enhance quality, safety, and efficiency.
The Challenge
Formule ETS’ challenge was to look for seals capable of withstanding the high temperatures and speeds that were demanded by their electric race car. Previously used elastomers degraded under these operating conditions.
Hi-Tech Seals’ Solution
We collaborated closely with Formule ETS to identify the right sealing solution. During this process, we found that the properties of the elastomer seals they were using did not meet the performance requirements of the vehicle, which led to premature degradation. We supplied them with Double Lip Oil Seals made from specialized materials with properties needed to withstand the vehicle’s high temperatures and speeds.
The Results
Formule ETS received the Double Lip Oil Seals and delivered impressive results. This contributed significantly to the overall increase in speed and the success of the engine’s development.
