Double-flexibility and three-speed speed adjusting water pump

Abstract

The invention discloses a double-flexibility and three-speed speed adjusting water pump. A water pump shaft is arranged in a water pump shell. The water pump shaft is an inner integral ball bearing. A water seal and an impeller are arranged at one end of the inner integral ball bearing, and a shaft at the other end of the inner integral ball bearing penetrates a center hole of the water pump shell and extends to the outer side of the water pump shell. A double bearing is arranged at the exterior of the water pump shell, and the outer ring of the double bearing is connected with a belt wheel. An electromagnet core is arranged in a cavity in the inner side of the belt wheel and is connected with the water pump shell. The outer side of the belt wheel is fixedly connected with a drive disc, a soft iron disc is embedded in the drive disc, and a circle of permanent magnet is arranged at the position opposite to the soft iron disc. A large friction disc, a small friction disc, a magnet fixing disc and a composite drive disc are arranged in a cavity formed by the drive disc and the belt wheel. The large friction disc and the small friction disc are riveted to a large spring and a small sprig correspondingly. The large spring and the small spring are connected to the composite drive disc and the magnet fixing disc correspondingly. A circle of permanent magnet is distributed on the outer ring of the magnet fixing disc, and the inner ring of the magnet fixing disc is connected to the water pump shaft through a bearing. Two circles of soft iron discs are embedded in the composite drive disc. The inner ring of the composite drive disc is in press fit with the water pump shaft.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a double-flexible three-speed speed-regulating water pump. Background technique [0002] In the prior art, the water pump of the automobile engine is generally a single-speed water pump. After the engine is started, the water pump has been running at high speed with the engine, driving the cooling water in the engine body, or rapidly circulating between the engine and the water tank, due to the cooling effect of the water tank, resulting in Water temperature, lubricating oil temperature, and cylinder wall temperature rise very slowly, resulting in insufficient fuel combustion and insufficient lubrication of moving parts, resulting in aggravated wear and tear of the engine in cold state. The power consumption of the water pump is always at the maximum state. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a dual-flexibl...
