Freewheel Clutches TRIZ Cases

A rotating and axially movable transmission member tilts opposite cams separately for smoother clutch mode switching with less noise and wear.

A punched sheet-metal coupling element and mirror-symmetrical wire spring secure freewheel engagement while saving space and cost.

A radial-moving transmission member lets this clutch switch drive states automatically, cutting manual intervention and axial thickness.

Sequential wedge and interlock engagement stabilizes torque transfer in freewheel hubs, reducing slippage while preserving coasting.

Phase-shifted cam grooves move clutch cage rings independently, enabling compact four-mode switching with smooth transitions and lower failure risk.

A spring-biased shutter plate and centrifugal claw release switch a ratchet clutch between lock and one-way modes without bulky actuators.

An integrated folded coupling rim lets the sheet metal cage lock to the freewheeling member with higher rigidity and easier assembly.

A tilting claw with a torque transmission unit increases tooth contact area, lowering surface pressure and improving ratchet clutch durability.

Staggered cam rotation cuts disengaging torque in a cam clutch, improving responsiveness, reducing surface damage, and extending service life.

A cam clutch paired with ratchet pawls enables fast, low-force mode switching while maintaining torque capacity and reducing clutch noise.

Roller pockets placed clear of the annular spring cut machining complexity, enable better roller positioning, and reduce cam clutch resistance.

Calculated strut force timing uses notch plate speed and notch spacing to cut clutch energy loss while maintaining reliable transmission shifts.

An interlocking coupling disk gives the sheet metal cage a rigid, secure fit on the freewheeling member while simplifying assembly.

A friction element adds preset torque between gear and housing to keep tooth flanks engaged and suppress freewheel noise during load changes.

A rotating snap-fit cam eases cage ring assembly, prevents cam fall-out, and protects the biasing member for better torque transmission.

Inclined asymmetric meshing surfaces stabilize claw motion during one-way free rotation, reducing violent movement and improving clutch durability.

Sequential multi-angle pawl engagement reduces backlash and wear while maintaining precise one-way torque transmission under strong impact loads.

Alternating bearing and holding portions in a resin retainer prevent cam jamming while cutting clutch weight and part count.

Cut-away retainer sections relieve radial assembly stress in a one-way clutch, reducing weight and preventing resin retainer damage.

Using stacked cam plates and a connecting pin, this case cuts machining cost while enabling center of gravity tuning and faster clutch response.

Asymmetrical clutch teeth and biased claw members stabilize one-way torque transfer by reducing claw oscillation and wear.

An axially movable cam orientation changer tilts engaging cams for quicker mode switching, higher torque capacity, and compact axial packaging.

Rollers protruding beyond the cage ring carry axial load in less space while reducing machining complexity and rotational resistance.

Offset pawl holding angles and elastic biasing help all clutch pawls engage stably, improving torque sharing and preventing overload damage.

Friction resistance lets opposing cam groups lift off without wedging, cutting switching force and raceway damage in a compact cam clutch.

Cam surfaces and dual spiral lock snap rings improve roller clutch support, retainer plate engagement, and assembly stability.

A cam attitude change mechanism stabilizes cam position and cuts direction-switching delay for more consistent clutch engagement.

A passive and active one-way clutch work together to manage forward and reverse torque flow with less actuation complexity and delay.

A cam-pawl coupling times single-turn fork motion to simplify baler drive transfer, cut wear, and keep bale shape uniform.

A cam-driven radial locking element replaces friction-based back-stop designs, enabling compact one-way shaft transmission without external power.
