Electronic cooling water pump of variable-flow engine

Abstract

The invention discloses an electronic cooling water pump of a variable-flow engine. The pump comprises a pump body, a shaft connected bearing, a flange and an impeller, wherein the shaft connected bearing is arranged on the pump body; the flange and the impeller are arranged at the two ends of the shaft connected bearing respectively; and the flange is in transmission connection with a belt pulley through a clutch mechanism. The pump is characterized in that: a spring strip which facilitates separating a driven plate from the belt pulley is arranged between the flange and the belt pulley; the clutch mechanism comprises a clutch bearing, a magnetic body A which pulls in the driven plate and the belt pulley and a coil which can generate a magnetic field repellent to the magnetic body A after being electrified; the magnetic body and the coil are arranged on a bracket; the electrification signal input end of the coil is connected with the output end of an electronic control unit which can acquire the temperature of engine cooling liquid; and a magnetic body B is pressed into the belt pulley. Engagement and disengagement between the driven plate and the belt pulley is realized by the coil in an electronic control way, so that a cooling system is driven appropriately, quantitatively, accurately and reasonably. The pump has the advantages of low energy consumption, quick response, low noise, high accuracy and long service life.

Description

technical field [0001] The invention relates to an engine cooling system assembly, in particular to an engine electronic cooling water pump. Background technique [0002] With the rapid development of the automobile industry and people's high attention to the environment, energy conservation and emission reduction has become one of the most concerned topics in the global automobile industry. [0003] Petroleum is a non-renewable resource. With the development of the world economy and the continuous improvement of people's living standards, petroleum resources are consumed at an alarming rate every year. And in the oil resources that are consumed every year, a large part is consumed on automobiles. Therefore, the energy-saving problem of automobiles has been greatly concerned by people all over the world. Governments of various countries have successively issued laws and regulations and various measures to encourage the research and development of energy-saving vehicles. T...
