By nesting a larger rubber absorber between the clutch sleeve and boss, this case cuts axial clutch size while improving impact energy absorption.

Wireless sensing on the clutch pressure plate sends wear data to the CAN line for timely maintenance and reduced damage to connected parts.

Radial pressure zones around an axial spacer spring cut disengaged drag torque while preventing cone formation in clutch friction elements.

An oil passage built into the clutch pressure plate feeds oil directly to pressure-plate-mounted driven clutch plates for more reliable engagement and release.

Temporary friction contact restrains the gear body only during axial shifting, cutting drag in motor engagement and freewheeling states.

Separate inclined tracks and a rotatable pin cut clutch hub wear, improve casting tolerance, and smooth servo-to-slipper torque transfer.

Thin elastic metal sheets let clutch discs move independently in the axial direction, reducing reaction forces and improving engagement control.

A ramp-actuated disconnect shaft and brake stop PMG rotor spin-down at 0 rpm, preventing fault currents after a short circuit.

A pivoting push ring and bearing let a motor-driven clutch actuator replace high-pressure oil systems while maintaining alignment and reducing wear.

Embedded conductive elements let clutch wear be tracked through resistance changes, avoiding visual inspection and complex displacement sensors.

Support teeth, a collar cavity, and oil passageways help the clutch hub resist flexing under load while dissipating heat from plate friction.

A rotary damper flexes the wrap spring at startup, enabling single-hub clutch engagement with fewer parts and simpler assembly.

Threaded drivers, brake plates, and friction discs enable bidirectional torque transfer while automatically locking rotation when power is removed.

A two-height internal tooth crown creates a precise axial stop for the support ring, cutting clutch carrier complexity and production time.

A compressed, rounded base rim prevents friction pad delamination and lowers drag torque from sharp fibrous cutting edges.

Dynamic wet clutch oil-flow mapping balances cooling demand with energy use while preventing clutch flutter in disengaged operation.
