Disconnect Clutch

  • Cam Ratchet
  • Roller Ratchet
  • Cam & Roller One-way Clutch

We have pushed our technology to the limits in shortening the response time for switching between 2WD and 4WD in e-Axles. We offer an outstanding lineup of products to match a wide variety of disconnect applications. We offer our disconnect solutions as a set with actuators as well.

Product Lineup

Cam Ratchet Selectable Clutch

Ratchet function added to the cam and roller
Full disconnect functionality

Selector switching between 2WD and 4WD in forward movement

  • Selector switching between 2WD and 4WD in reverse motion

    Inner ring slides for ON-OFF switching
    *A separately purchased actuator is required.

    4WD can be implemented in reverse by connecting the ratchet section with the selector when moving rearward.

  • Fastest switching time (forward movement)

    The cam is always on standby and engages immediately without actuator action.

  • Regeneration in both forward and reverse movement

    By connecting the ratchet section with the selector, reverse input from the wheels can be transmitted to the motor to achieve regerneration during both forward and reverse movement.

Roller Ratchet Selectable Clutch (ON-OFF Type)

ON-OFF function is equivalent to a dog clutch, plus the ability to switch during differential rotation

Selector switching between 2WD and 4WD in forward movement

Selector switching between 2WD and 4WD in reverse motion

Unique structure minimizes selector switching time

Regeneration in both forward and reverse movement

Two-way locking mechanism enables regeneration

ON-OFF switching possible even during differential rotation

Cam & Roller One-way Clutch

The lightest and most compact model for disconnecting during forward movement

No selector nor actuator required

Automatic switching between 2WD and 4WD in forward movement

Automatic ON-OFF when the rotation speed is matched without the need for a selector or an actuator

Fastest switching time (forward movement)

No selector operation is required, thereby allowing the quickest possible changeover times
