Mechanical Actuated Clutches TRIZ Cases

Spherical cup and ring geometry compensates for run-out in clutch release bearings, reducing pedal effort and extending bearing life.

An annular shield with folded flanges clamps the outer ring of a clutch thrust bearing, reducing friction torque in all-wheel drive drivelines.

A clutch actuator plunger absorbs transient loads via a low spring constant mechanism to protect drive components.

A clutch actuation system estimates required force to apply precise motor torque for engagement.

A vehicle power transmission device uses a mechanical hydraulic pump to supply fluid to first and second disconnection devices.

A detection valve moves based on inlet and outlet pressure differences to activate a switch, resolving inaccurate filter replacement timing.

A transmission control valve manages hydraulic clutch pressure to maintain disconnection during gear shifting operations.

Integrating the electromagnet and rotor via a press-fitted bearing support tube stabilizes axial overlap distance, resolving inconsistent attraction forces.

Partial synchronization clutch opening distributes torque between axles, preventing unnecessary switching that reduces traction efficiency.

Separate holders from protective sleeves to prevent wire damage during injection molding while simplifying the manufacturing process.

An integrated clutch regulator reduces weight and cost by merging pressure control with a resonator that absorbs vibration.

A vehicle power switching device uses a solenoid-driven coupler to interconnect the differential and axle for four-wheel drive engagement.

Non-rotating planetary roller carriers eliminate slip-induced pitch changes, removing the need for distance sensors.

A disconnecting overload clutch uses paired transmission bodies held by springs to transmit torque between a hub and pressure flange.

A planetary roller screw actuator uses a stop spring and angle sensor to detect spindle rotation.

Segmented cam follower provides dwell zones for reliable gear engagement while reducing shift force.

A bi-directional overrunning clutch friction disk mechanism uses a slip disk to bias an inner hub member against a roll cage plate.

Replacing toothed sleeves with a friction-based one-way clutch eliminates impact wear and delays, enhancing durability and response speed.

Elastic lugs on the dog ring push the sliding gear back to neutral position, preventing actuator jamming from insufficient stroke.

Cam surfaces generate separation forces against an adjustable spring, resolving the trade-off between precise torque control and device complexity.

A vehicle clutch drive unit uses a dither function to continuously vary position and prevent overheating.

Extended shift sleeve contacts synchronizer rings simultaneously, eliminating the neutral period that causes power cutoff and driver discomfort.

Curved cam tracks decouple clutch displacement from spring wear, stabilizing axial force.

Asymmetric sleeve and blocker teeth reduce high release loads caused by traditional angled designs while maintaining wear resistance.

A multi-clutch transmission control system selects power shift mode to maintain continuous torque delivery during gear changes.

Plate-shaped spring support pieces with axial gaps allow easy insertion of elastic members, preventing interference and deformation during mounting.
