Contents of research and development
① Performance Development for ultra flat and high effective fuel-efficiency type
- The most suitable shape design for new concept torus of round high form.
- Development of the most suitable design technology for blade that considers change of flow sectional area by exfoliation.
- Development of performance to enhance power performance and fuel-efficiency at the same time. (efficiency 89%)
② Lock up clutch development for full slip
- Development of Piston injection hole technique for cooling capacity enlargement while slip lock-up.
- Development of 2- way Lock up clutch for slip control to secure torque capacity through maintenance of differential pressure properly and effective cooling by controlling flux of the friction surface properly.
(working slip lock up mode from 1,000rpm)
③ Damper system development for controlling slip
- Low hardness damper development for decreasing booming noise of a front wheel drive.
- Turbine damper system development for rear-wheel drive automatic transmission vehicles.
- Twin damper system design that is optimized to multistage A/T and security of intellectual property rights.
④ Development of friction lining with shudder resistance for Slip control
- Development of test code for friction lining test regarding slip control of lock up clutch.
- Development of friction lining with shudder resistance that is optimized in slip control by friction performance test.
⑤ Development of Multi-function wet type clutch
- Design and prototype development/test of Wet type clutch for closed-type 3-line structure that combines with start clutch which maximize cooling capacity of friction lining.
- Concept design of torque converter for hybrid that apply round high(?) torus of microminiature type.
⑥ Development of mass-production specification that consider cost and productivity
- Applying slip lock-up technology to mass-production by improvement design of production model.
- Design and development the leader model for 6-speed automatic transmission as compact size/meddie size/full size model
- The selection of new specification development company by The professional Transmission comany in Germany, Japan, Australia.
