Problems solved by technology

[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

Embodiment 1

[0023] Such as Figure 4 As shown, the double-flexible three-speed speed-regulating water pump in this embodiment includes a water pump casing 1, a pulley 8, and a water pump shaft 4. The water pump shaft 4 is a shaft-connected bearing. The left end is equipped with water seal 3 and impeller 2, and the right end of water pump shaft 4 passes through the center hole of water pump casing 1 and extends out of water pump casing 1. Water pump casing 1 is equipped with double-row bearing 9, and pulley 8 is set on the water pump through double-row bearing 9. On the shell 1, the inner ring of the double row bearing 9 is fixedly connected with the water pump casing 1, and the outer ring of the double row bearing 9 is fixedly connected with the pulley 8, and the pulley 8 can rotate around the double row bearing 9.

[0024] Such as figure 2 and Figure 4 As shown, the inner cavity of the pulley 8 is equipped with an electromagnet core 7, the electromagnet core 7 is fixedly connected wi...

Embodiment 2

[0031] The difference between the second embodiment and the first embodiment is that the second embodiment does not include the drive disc 11 and the soft iron disc 19, and of course there is no cavity formed by the drive disc 11 and the pulley 8, and the positions of the two turns of the soft iron disc are changed. Among them, the two circles of soft iron discs are: the soft iron disc 15' located in the inner ring and the soft iron disc 17' located in the outer ring, the position of the soft iron disc 15' located in the inner ring and the permanent magnet 14 on the magnet fixing disc 21 Correspondingly, a permanent magnet 18 ′ is embedded on the outer end surface of the pulley 8 , and the soft iron disk 17 ′ on the outer ring corresponds to the position of the permanent magnet 18 ′ on the pulley 8 .

[0032] The working principle and working process of the second embodiment are basically the same as those of the first embodiment, and will not be repeated here.

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...
