Voir Technology “Upgrades Again” the Voir®ETV™ Three-in-One Oil-Cooled Transmission System Protection Solution

Release time：2022-07-04

Integrated automotive engineering enables ultra-high rotational speeds, but also poses greater challenges for oil seals. Voir®’s ETV™ three-in-one oil‑cooled transmission system has undergone its third upgrade, further enhancing the reliability and stability of transmission components while reducing installation complexity and overall system costs.

Voir® ETV™ three-in-one oil‑cooled transmission system protection solution dynamically balances internal and external pressures, ensuring reliable operation and resolving longstanding industry issues such as oil leakage and negative pressure, thereby delivering exceptional performance.
1. Speed upgrade: from 13,000 RPM to 17,000 RPM to 18,000 RPM; no oil leakage after 1 minute.
2. The waterproof rating has been upgraded from IP67 to IP68 to IP69K, and the oil‑resistance rating has been upgraded from Level 7 to Level 8.
3. Withstands water pressure up to 60 kPa for 60 seconds, balancing internal and external pressures to extend service life.
4. Air permeability upgraded to 6 ± 1 L/min at ΔP = 7 kPa.

Voir engineer: “Our independently developed Voir® ETV™ solution products have been widely adopted by German-, American-, and Chinese‑brand automakers, delivering significant economic and social value, enjoying high market recognition, and ensuring consistent automated production.
