Bonded Piston Seal (BPS)

Installed within the planetary clutch of an automatic transmission, it engages and disengages the clutch using hydraulic pressure to perform gear shifting.

Function

Transmission and release of hydraulic pressure through sealing

Size

Approx. Φ100mm ~ Φ200mm

Weight

Approx. 100g ~ 500g

Features

Previously, D-rings were assembled onto die-cast or forged components. However, this has transitioned to BPS (Bonded Piston Seal) and BCS (Bonded Clutch Seal) technology to achieve a more compact design, cost reduction, and superior responsiveness.

 

  • Achieved a more compact design compared to conventional assembly methods.
  • Reduces overall manufacturing and assembly costs.
  • Significantly enhanced gear-shifting response times.
PyungHwa Advantages
  • Leveraging proprietary rubber compounding technology, we apply optimized materials capable of withstanding extreme environmental conditions.
  • The application of a low-friction optimized design improves shift responsiveness and contributes to enhanced fuel economy.
