Starter unit and method for matching starter units in drive systems to different limiting conditions, in particular different drive engines

Hydrodynamic coupling, operating resources supply system for hydrodynamic coupling and starter unit with a hydrodynamic coupling

Starting unit and gearbox unit with a starting unit

Hybrid drive system comprising a hydrodynamic clutch particularly for motor vehicles

MOTOR VEHICLE DRIVE TRAIN COMPRISING A HYDRODYNAMIC RETARDER

Abkoppelbarer hydrodynamischer Retarder und Steuerungsverfahren hierfür

Powertrain for motor vehicle e.g. truck, has hydrodynamic retarder which is mechanically connected to drive shaft through separation clutch

Anti-runback system for road vehicle being driven on slope has control computer with control members connected to impeller and turbine wheels of torque converter between engine and gearbox

Method for reducing absorbable torque of hydrodynamic clutch in high slip ranges entails filling clutch with desired degree of filling of predefined value, and especially minimum filling level, when clutch is in operation

Optimizing driving off process in drive train with driving off unit and hydrodynamic clutch involves periodically determining vehicle parameters and controlling clutch depending on parameters
