Fluid Actuated Clutches TRIZ Cases
- Friction Engagement Cooling via Radial Oil Pathway
A radial lubricating oil pathway cools overlapping friction engagement elements using a single peripheral temperature sensor.
- Clutch Control Apparatus Suppressing Oil Leakage via Hydraulic Pressure
A clutch control apparatus applies hydraulic pressure to a piston chamber to retain seal member tension and suppress oil leakage.
- Dual Wet Clutch Radial Offset Design Reduces Inertia
An axial extension of the outer disc carrier features a radial offset that reduces system inertia and wear while maintaining torque transmission reliability.
- Wet Clutch Touch Point Learning via Hydraulic Pressure Analysis
A controller detects clutch engagement by analyzing working hydraulic pressure changes in a wet clutch system.
- Adaptive Clutch Engagement Control via Torque Feedback
Dynamic pressure adjustment responds to torque fluctuations exceeding median thresholds, reducing energy absorption and improving fuel economy.
- Normally Open Friction Disc Clutch Using Centrifugal Lever Torque
Centrifugal lever torque closes the clutch at speed while a return spring keeps it open when stationary, eliminating diaphragm springs.
- Friction Lamella Groove Pattern for Uniform Cooling
Oblique second grooves channel coolant toward the inner friction surface, countering centrifugal forces that otherwise starve the inner area of cooling oil.
- DCT Oil Pump Control via Pressure Models
A DCT oil pump controller estimates line pressure using regression models to manage hydraulic supply without dedicated sensors.
- Four-Wheel Drive Vehicle Propeller Shaft Speed Synchronization
Selective multi-plate clutch engagement synchronizes propeller shaft rotation to suppress noise and vibration during mode switching.
