Abstract
A fluid pump (10) for a motor vehicle comprising a pump rotor (20) for pumping a fluid, a shaft (12) for driving the pump rotor (20) and a clutch (16) for the switchable coupling of the shaft (12) to the pump rotor (20). The clutch (16) is designed to connect the shaft (12) to the pump rotor (20) in a positive-locking manner and to separate said shaft from said pump rotor.
Claims17
A fluid pump (10) for a motor vehicle, the fluid pump comprising:
- a pump rotor (20) for pumping a fluid;
- a shaft (12) for driving the pump rotor (20);
- a clutch (16) for the switchable coupling of the shaft (12) to the pump rotor (20);
- characterized in that the clutch (16) is operable to connect the shaft (12) to the pump rotor (20) in a positive-locking manner and to separate the shaft (12) from the pump rotor (20),
- wherein the clutch (16) comprises a coupling element (36) which is axially displaceable with respect to the shaft (12) and is operable to come in engagement with a further coupling element (42), and
- wherein the axially displaceable coupling element (36) comprises a helical groove (56), in which a pin (48) can be latched in a radial direction in order to move the axially displaceable coupling element (36), when rotated, away from the further coupling element (42).
