Cooling circuit pump for a motor vehicle

Abstract

The invention relates to a cooling circuit pump for a motor vehicle, having a stator which is arranged in a motor housing ( 14 ) and in which a rotatably mounted rotor is received. It is proposed that the stator ( 12 ) is received in the motor housing ( 14 ) in a positively locking manner.

1 . A cooling circuit pump for a motor vehicle, having a stator ( 12 ) which is arranged in a motor housing ( 14 ) and in which a rotatably mounted rotor is received, characterized in that the stator ( 12 ) is received in the motor housing ( 14 ) in a positively locking manner. 
     
     
         2 . The cooling circuit pump according to  claim 1 , characterized in that the stator ( 12 ) comprises a laminated core which is mounted by means of a snap hook device ( 16 ,  30 ) in the motor housing ( 14 ). 
     
     
         3 . The cooling circuit pump according to  claim 2 , characterized in that snap hooks ( 16 ,  30 ) are disposed on an inside of the laminated core radially around a circumference of the motor housing ( 14 ) in a distributed manner, wherein latching lugs ( 20 ,  32 ) formed on an end of the snap hooks ( 16 ,  30 ) engage around the laminated core in a positively locking manner. 
     
     
         4 . The cooling circuit pump according to  claim 3 , characterized in that the snap hooks ( 16 ) are attached to a support ring ( 18 ). 
     
     
         5 . The cooling circuit pump according to  claim 4 , characterized in that a tolerance compensation element ( 22 ) is disposed between the support ring ( 18 ) and the laminated core. 
     
     
         6 . The cooling circuit pump according to  claim 3 , characterized in that the snap hooks ( 16 ) are fastened to a rotor can ( 24 ) disposed between the stator ( 12 ) and the rotor. 
     
     
         7 . The cooling circuit pump according to  claim 3 , characterized in that the laminated core of the stator ( 12 ) has a step or a ledge ( 34 ) in an axial extension thereof, on which the latching lugs ( 32 ) of the snap hooks ( 30 ) engage. 
     
     
         8 . The cooling circuit pump according to  claim 3 , characterized in that the snap hooks ( 16 ) are attached to a support ring ( 18 ) which is manufactured as one piece together with said snap hooks ( 16 ) and the motor housing ( 14 ).
