Fluid Actuated Clutches TRIZ Cases

A clutch pawl uses an intermediary return spring to restore position against a ratchet wheel without a dedicated lug.

Embedded wear indicator releases particulate matter upon friction plate erosion, eliminating manual disassembly and reducing maintenance downtime.

Radial slots on wet clutch core plates attenuate axial displacement to minimize spin losses and thermal degradation at high rotational speeds.

Pneumatic toothed sleeves disconnect drivetrain axles to reduce fuel consumption and tire wear in heavy cargo vehicles.

A compact airactuated cone clutch fan assembly uses a central piston mechanism to reduce size and weight.

Shift actuator moves transmission to neutral before engine start, eliminating manual intervention and preventing starting failures.

Switching valve blocks pressure supply to third engagement element, preventing unexpected shocks from solenoid failure.

A sheet metal cylinder uses segmented synchronization profiles with circumferential supporting elements to maintain structural integrity.

Opposing dual actuators compress the clutch pack to distribute heat evenly, eliminating localized temperature spikes without increasing assembly size.

A plastic cylinder housing uses a conical reinforcement sleeve fastened via a snap connection to resist hydraulic pressure.

A transmission shaft pressure relief valve adjusts opening thresholds based on rotational speed to stabilize clutch engagement.
