A controllable drive () suitable for a motor vehicle coolant pump () comprises a rotatably mounted shaft (), a driven member () which is rotationally fixedly mounted on the shaft (), a driving member () which is mounted so as to be rotatable relative to the shaft (), and a coupling region () which is arranged between the driving and driven members () and holds a viscous fluid. At least one first flow path and at least one second flow path connect a fluid reservoir to the coupling region (), and an actuation device () changes at least one passage opening of at least one flow path. A coupling housing () is connected to the driving member (), and the actuator () is arranged within the coupling housing ().

Controllable drive for a motor vehicle, in particular for a coolant pump

A regulatable drive for a motor vehicle, in particular for a water pump in a motor vehicle, has a rotatably mounted shaft, on which is located a rotatably mounted drive member and a rotationally fixed driven member. Between the drive member and driven member, a coupling region is defined, which can receive a viscous fluid for selectively coupling the drive member and driven member. The regulatable drive includes at least one first and at least one second flow path, which connect a fluid storage space to the coupling region, and it has a device which can be varied in its position by means of at least one actuator and which varies at least one passage orifice of at least one of the flow paths.

Regulatable drive for a motor vehicle component

The invention relates to a heating device for motor vehicles with an internal combustion engine and a coolant circuit. The heating device () comprises a heat-generation compartment () with a cooling jacket () around which a coolant flows, and a rotor () mounted on a drive shaft (). The cooling jacket () is part of a cooling chamber () that comprises a coolant inlet () and a coolant outlet (). A pump wheel () is disposed in the cooling compartment (), is driven by the drive shaft () and circulates the coolant.

Heating device for motor vehicles

The invention relates to a heating device, in particular for motor vehicles, for generating frictional heat by liquid friction with a housing which is arranged in a stationary position and has a working space and a motor-driven rotor in the working space.

Heating device suitable for motor vehicles

Fluid friction clutch is disclosed of the type having a primary disk ( ) fastened on a driving shaft ( ) comprising magnetic material and a driven clutch housing ( ) surrounding the primary disk and mounted with a hub ( ) on the shaft ( ), and with a working chamber ( ) formed between primary disk and clutch housing, into which a shear fluid can enter from a reservoir chamber ( ) according to the position of a valve plate ( ) opening or closing a connecting opening ( ) between reservoir chamber and working chamber and having an armature ( ) lying in reach of the shaft ( ), which can be shifted by magnetic force produced by a stationary electromagnetic coil ( ) arranged on the driven end of the shaft ( ), wherein the hub ( ) of the clutch housing ( ) facing the electromagnetic coil ( ) is provided with an inserted first conducting ring ( ) of magnetic material which is coupled magnetically at one end ( ) with the electromagnetic coil ( ) and at its other end facing the working chamber ( ) adjoins a second conducting ring ( ) of magnetic material which passes through the primary disk ( ) and ends in an area in front of the armature ( ) of the valve plate ( ).
