Torque limiter clutchComponent under development

  • Tapering type

The torque limiter clutch is a device that protects mechanical equipment by preventing the transmission of excessive torque when overloaded.
Tsubaki is developing three torque limiter clutch types to meet customer needs.

Contributing to miniaturization, cost reduction, and energy saving of customers’ products

Product Structure

Designed for compactness and durability.

Torque Limit Mechanism

When torque exceeds the set torque, slip occurs on the inner ring side, limiting toque transmission between the inner and outer rings.

  • 1. Torque transmission

    During normal torque generation, torque is transmitted between the inner and outer rings.

  • 2. Excessive torque input

    When excessive torque is input, a strong force is applied between the outer and inner rings.

  • 3. Torque release

    When the force exceeds a certain level, the inner ring and shaft slide to release torque.

Future Applications

e-Axle Drive Unit

Limits the impact load from tires when driving on rough roads, etc., and contribute to the miniaturization of each component and the unit as a whole.

Other potential applications include electric sunroof/sunshade/retractable hardtop/e-bike overload protection and Limited Slip Differential replacement.
If there are any applications our products may fill, please feel free to contact us.
