Abstract:
A coolant pump for providing a coolant to an engine includes a pump frame, a rotatable rotor shaft, a pulley wheel co-rotatably fixed to the rotor shaft, an axially shiftable ferromagnetic rotatable pump wheel, and an electromagnetic wet friction clutch arrangement. The pump wheel is axially shiftable with respect to the rotor shaft and the pump frame. The clutch arrangement comprises a static electromagnet, a clutch disk co-rotatably supported by the rotor shaft, a first clutch friction surface arranged at the clutch disk and a thereto corresponding second clutch friction surface arranged at the pump wheel, and a separate stop friction surface arranged at the pump wheel and a thereto corresponding static stop friction surface arranged at the static pump frame. The electromagnet, when fully energized, axially attracts the pump wheel so that the separate stop friction surface and the static stop friction surface engage to stop the pump wheel.

Claim (Index 12):
A mechanical switchable automotive coolant pump for providing a liquid coolant for an automotive engine, the mechanical switchable automotive coolant pump comprising:\n a static pump frame; a rotor shaft configured to rotate, the rotor shaft being rotatably supported at the static pump frame; a pulley wheel configured to be co-rotatably fixed to the rotor shaft and to be mechanically driven by the automotive engine; a pump wheel comprising a ferromagnet, the pump wheel being configured to rotate and to be axially shiftable, and to be rotatably supported and axially shiftable with respect to each of the rotor shaft and the static pump frame; and an electromagnetic wet friction clutch arrangement comprising,\n a static electromagnet configured to be energized, \n a clutch disk which is co-rotatably supported by the rotor shaft, \n a first clutch friction surface arranged at the clutch disk, \n a second clutch friction surface arranged at the pump wheel, the first clutch friction surface corresponding to the second clutch friction surface, \n a separate stop friction surface arranged at the pump wheel, and \n a static stop friction surface arranged at the static pump frame, the separate stop friction surface corresponding to the static stop friction surface, \n wherein, \n the static electromagnet, when fully energized, axially attracts the pump wheel so that the separate stop friction surface and the static stop friction surface engage with each other, thereby stopping the pump wheel.
