Abstract

The invention provides an automobile water pump comprising a shell and a water pump shaft. A first end of the water pump shaft is provided with an impeller matched with the water pump shaft in a linkage manner, and a second end of the water pump shaft is provided with a driving device driving the water pump shaft to rotate. The impeller comprises a bushing provided with spline grooves, and splines matched with the spline grooves are arranged on the water pump shaft. Due to the fact that the spline grooves are formed in the bushing and the splines matched with the spline grooves are arranged on the water pump shaft, the impeller and a rotary shaft can be mounted fittingly and fixed firmly, and demounted easily.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to an auto water pump. Background technique [0002] The automobile water pump is an important part of the automobile engine. The automobile water pump includes a casing and a water pump shaft is arranged in the casing. One end of the water pump shaft is provided with an impeller that cooperates with the water pump shaft, and the other end is provided with a driving device for driving the rotation of the water pump shaft. , the driving device drives the water pump shaft to rotate, thereby driving the impeller to rotate, the water pump shaft is also provided with a water seal, and the water seal is used to prevent water from entering the casing and affecting the work of the water pump shaft. [0003] There are two main methods for the existing impeller to be installed on the water pump shaft: one is to install it on the water pump shaft in the way of interference fit. The impeller in this w...
