Friction Clutches TRIZ Cases

An extender links clutch subassemblies to varying cover plates, enabling aftermarket adaptability without new segment development.

Axial clearance between the first friction washer and the hub prevents pinching stresses during thermal expansion, extending service life.

An asymmetrical hub profile with distinct marking elements prevents incorrect axial alignment during clutch assembly.

A differential disconnect system uses a translatable collar to selectively connect drivetrain shafts.

Segmented friction lugs reduce contact area to lower drag torque, cutting fuel consumption and mass while maintaining torque transmission capacity.

Wave springs separate friction plates to eliminate drag and spin losses during disengagement.

A switchable ratcheting wedge clutch uses a movable cage to pivot a pawl within an inner race pocket for controlled rotational engagement.

A clutch support plate uses protruding ribs to distribute axial forces across rotors while maintaining a thin profile.

A wedge clutch uses a tapered hub surface and cage assembly to control radial movement of segments for power transmission.

Variable metering openings adjust cooling fluid flow based on clutch state, reducing drag torques and energy losses from viscous friction.

A friction clutch sensor spring uses a crowned contact surface and ball mechanism to alter lever geometry.

A clutch device uses a radial cam mechanism to generate axial pressing force between the pressure plate and clutch center.

Annular ring and spacer assembly constrains axial washer movement to reduce friction noise and wear while maintaining clutch disengagement force.

Splitting the second disk pack creates two torque paths, reducing leaf spring load and preventing buckling under high transmission forces.

Rivets weld to mountings and deform into flanges, eliminating holes that reduce surface area and lower manufacturing costs.

A friction ring uses a resin mixture with aligned short fibers to form a wear-resistant lining.

Molded bearing blocks replace manganese phosphate coatings to lower friction and wear in overrunning clutches.

Tapered grooves between friction segments channel oil inward, improving cooling efficiency and preventing thermal degradation in wet clutches.

Laser cutting creates multiple pawl tongues from a single blank, resolving the trade-off between tongue quantity and production time in slack adjusters.

A control device corrects current command values to maintain accurate transmission torque in multiple-disc clutch systems.

A segmented clutch structure distributes torque across multiple friction interfaces to reduce operating force.

A clutch-brake assembly uses spring retainers with projecting portions to telescopically position springs and transmit force between a piston and base member.

Eliminates plastic coatings and torque fluctuations by deforming the adjusting screw thread to lock the operating point against vibration.

Radial oil grooves channel clutch fluid from the output shaft to outer components, solving lubrication gaps caused by flattened mounting surfaces.

Laser welding connects segmented carrier sheets to resolve alternating stress stability issues while maintaining production cost efficiency.

A cylindrical clutch assembly uses radially movable friction pads to transmit torque between coaxial members.

Spring-biased struts shift the coupling assembly between modes, eliminating external control elements that increase mechanical complexity.

A wet multiple-disc clutch supplies oil radially through a nozzle and clutch boss to lubricate drive plates without axial shaft machining.

A transmission-grade plastic support shim absorbs axial forces transmitted through the roller cage flange.

A clutch damper disk uses a non-circular engagement hole and specific cutouts to manage compressive loads.

A path-controlled adjustment device maintains a constant actuation path using a flexible tension element and drive spindle.

Rotating arms project a friction shoe against a bell-shaped member surface, enabling independent exhaust brake use regardless of gear engagement.

A clutch cam ring rotates to maintain engagement position consistency as the disc wears.

A concentric connecting bolt clutch arrangement simplifies chopping drum adjustment via external pressure plate operation.

Centrifugal force drives a J-shaped pawl into a convex boss, preventing dislodgement and maintaining reliable locking under high-speed operation.
