As shown in fig. 2, a cantilever-free driving water pump according to a preferred embodiment of the present invention includes: a water pump housing 1, a first water pump bearing 2, a water pump shaft 3, a water pump impeller 4, a second water pump shaft 5 and a drive gear 6. The first water pump bearing 2 is disposed in the water pump housing 1 and is located at the rear end of the water pump housing 1. The water pump shaft 3 is transversely arranged in the water pump housing 1, and one end of the water pump shaft 3 is connected with the first water pump bearing 2. The water pump impeller 4 is disposed in the water pump housing 1 and is located at the front end of the water pump housing 1, and the water pump impeller 4 is connected to the other end of the water pump shaft 3. The second water pump shaft 5 is arranged in the water pump housing 1 and is close to the water pump impeller 4, and the second water pump shaft 5 is connected with the water pump shaft 3. And the driving gear 6 is arranged in the water pump housing 1 and is close to the first water pump bearing 2, and the driving gear 6 is connected with the water pump shaft 3.
In one embodiment of the present invention, the driving gear 6 is used to drive the water pump shaft 3 and the water pump impeller 4 to rotate, so that the water pump impeller 4 drives the cooling liquid in the water pump housing 1 to rotate.
