HS Type – hydraulically activated with straight toothing
 

The HS synchronous clutch coupling is a hydraulically activated synchronous clutch coupling with straight toothing. It automatically engages at low speeds when the input shaft overtakes the output shaft. The coupling can be disengaged at any speed by reducing the output to under ten percent and sending the corresponding signal to the hydraulic unit. When engaged, the HS synchronous clutch coupling functions like a classic gear coupling. Due to the straight toothing, the full positive and negative torque can be transmitted without disengaging.
