| 摘要 |
The invention relates to a coupling device (2, 40, 50) for a coolant pump (1) comprising at the least one drive shaft (10) with at least one coupling element (3) that is driven by means of the drive shaft (10), wherein the coupling device (2, 40, 50) comprises at least one thermal actuator (21, 22), which is designed such that the thermal actuator (21) is able to assume a first state. In said first state, the at least one couple element (3) is rotationally fixed to the drive shaft (10). The thermal actuator (22) can assume at least one second state, in which the at least one coupling element (3) is rotationally fixed to the drive shaft (10). |
