Fluid Actuated Clutches TRIZ Cases

Variable sweep increase of lockup clutch hydraulic pressure suppresses shock during complete engagement when zero-slip control fails.

Offset upstream and downstream oil passages reduce conduit resistance, preventing operation pressure generation at low temperatures.

Static expansion chamber absorbs clutch pedal vibrations between 50 Hz and 225 Hz, eliminating diaphragm wear while maintaining ride quality.

A ball detent latching clutch mechanism holds the apply plate engaged using mechanical locking.

A hydraulic clutch inching control device regulates oil pressure to maintain the clutch plate heat generation rate within safe limits.

Stamped clutch carrier merges hub and cover into single sheet metal unit with axially extending fingers.

A clutch actuation assembly integrates an automatic actuator within a hydraulic intermediate cylinder to enable seamless manual and automated shifting.

An optical wear sensor measures friction sector thickness in a clutch assembly, eliminating time-consuming visual inspections and reducing maintenance errors.

Strap springs elastically expand to create clearance between reaction plates and friction surfaces, reducing heat and wear from limited horizontal displacement.

Nested radial oil passages reduce axial length and complexity by merging separate fluid paths into a compact clutch drum structure.

Two radially outer spring sets in series transfer torque through a cover plate to reduce the overall spring rate of the damper assembly.

Misaligning the starting clutch valve relative to the vehicle longitudinal axis decouples longitudinal vibrations, minimizing clutch judder during engagement.

Elastic holding device maintains pressing force without continuous actuation, reducing energy demand during shift processes.

A piston rod joint clip device secures the rod within a stop ring using spring arms and latching projections.

Nesting the planetary gear mechanism inside the hollow output member reduces volume and noise while switching rotation direction.

A centering plate supports the pump drive wheel in an automatic transmission to decouple coercive forces from the clutch assembly.

Dual oil grooves on friction plates discharge lubricating oil to separate clutch components and reduce idle drag torque.

A hydraulic clutch assembly uses a fluid coupling mechanism to transmit torque and manage heat.

Protective bellows clip into a segmented fastening ring using piston axial movement for secure release bearing attachment.

A hydraulic cylinder unit uses a bayonet interface and separate plate to enable flexible mounting options.

Merging the piston arm and transfer plate into a single component eliminates sequential movement delays, ensuring rapid clutch release response.
