Pump, particularly coolant pump, for use in motor vehicle for conveying fluid, has coupling device, which has coupling element with latching contour and another coupling element with counter-latching contour

摘要

The pump (1) has a coupling device (14), which has a coupling element (15) with a latching contour (17), where the coupling element is connected with a rotor (2). The coupling device has another coupling element (16) with a counter-latching contour (19), where the latter coupling element is connected with a peripheral wheel (3). The latching contour is locked with the counter-latching contour in a form-fit manner during installation of the pump for torque-proof connection of the rotor with the peripheral wheel.
