| 1 | Brushless DC clutch actuator motor |
| 2 | Pressure spring |
| 3 | Recirculating ball nut |
| 4 | Rollers |
| 5 | Engagement lever |
The force required to close the clutches is largely generated by a compression spring via the mechanical system of the lever actuator. This force acts on the outer end of the engaging lever. This has the form of a rocker. The rollers form the central point of contact of the engagement lever.
The brushless DC clutch actuator motors are bolted directly onto the transmission clutch housing. The DC clutch actuator motor drives the threaded bar of the ball screw via gear teeth. Through rotation of the threaded rod, the recirculating ball nuts and thus the rollers are moved in an axial direction. Due to the axial movement of the rollers, the central support point of the engaging lever is displaced, as a result of which the leverage is altered.
