One-way clutch

Proprietary design supporting space-saving integration

This clutch features a unique structure that ensures concentricity by incorporating rollers.
There is no need for additional bearing arrangements on the customer side, contributing to a more compact and lightweight unit.

Cam & Roller Clutch

more Quickly, more Smoothly more Quickly, more Smoothly

Cam & Roller Type

The lightest and most compact model for disconnecting during forward movement

Structure

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

Unique design, proprietary to Tsubaki

Rollers are interspersed axially with the cams to insure concentricity. The result is reduced idling friction and quieter operation.

Applications of One-Way Clutch TechnologyElement Development in Progress

Ratchet function added to the cam and roller
Full disconnect functionality

Structure

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.
