Control arrangement for the temperature-dependent adjustment of the filling of a hydrodynamic clutch

摘要

Control arrangement for the temperature-dependent adjustment of the filling of a hydrodynamic clutch for the cooling fan drive of an internal combustion engine with at least two temperature sensors on the internal combustion engine, a control unit for the conversion of measured values and a solenoid directional control valve in the working medium circuit of the clutch, in which the control unit is designed as a two-position circuit with delayed elastic feedback action, which at any time uses only the greatest signal for individual setpoint deviations as a control variable for controlling the control valve. <IMAGE>
