Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology and relates to an electronically controlled silicone oil clutch water pump. Background Technology

[0002] The car water pump is a key component of the engine cooling system. Its function is to drive the coolant to circulate in the engine cooling system in order to maintain the normal operating temperature of the engine.

[0003] A search revealed that the authorized announcement number is CN210196118U, entitled "Utility Model of a Car Water Pump," which includes an impeller, a drive shaft, and a pump casing. Research and analysis revealed that although it has advantages such as high sealing performance and extended service life during use, it also has the following disadvantages to a certain extent.

[0004] For example, existing automotive water pumps use a constant speed design, which has the defect of insufficient temperature control accuracy. During cold starts, excessive cooling prolongs the engine warm-up time, and under high load, insufficient heat dissipation can lead to overheating failure. At the same time, its continuous high speed operation will continuously consume engine power, thereby increasing fuel consumption. In order to solve the above technical problems, we have designed an electronically controlled silicone oil clutch water pump. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by providing an electronically controlled silicone oil clutch water pump that can save energy, precisely control the water pump speed, and intelligently adapt the coolant flow to the working conditions. This avoids excessive cooling during cold starts and efficiently handles high-load heat dissipation, thereby significantly reducing power loss and fuel consumption.

[0006] The objective of this utility model can be achieved through the following technical solution: an electronically controlled silicone oil clutch water pump, comprising a pump body, a pulley movably connected to the left side of the pump body surface via a sealed bearing, a front cover bolted to the left side of the pulley, a shaft bearing penetrating the right side of the pump body, an impeller bolted to the right end of the shaft bearing, a connecting plate provided in the inner cavity of the front cover, a drive plate bolted to the right side of the connecting plate, a driven plate fixedly connected to the left side of the shaft bearing surface, a valve plate assembly provided between the drive plate and the driven plate, a speed plate fixedly sleeved on the right side of the shaft bearing surface, a voltage sensor and a speed sensor respectively provided on the top left side of the pump body, a protective cover bolted to the top left side of the pump body, and a solenoid valve provided inside the pump body.

[0007] This electronically controlled silicone oil clutch water pump mainly consists of a connecting plate, a drive plate, a driven plate, a valve plate assembly, a speed plate, a voltage sensor, a speed sensor, a protective cover, and a solenoid valve on the surface of the pump body. Through the connecting plate, drive plate, driven plate, valve plate assembly, speed plate, voltage sensor, speed sensor, protective cover, and solenoid valve, the pump speed can be precisely controlled, and the coolant flow rate can be intelligently adapted to the working conditions. This avoids excessive cooling during cold starts and can efficiently handle high-load heat dissipation, thereby significantly reducing power loss and fuel consumption.

[0008] In the aforementioned electronically controlled silicone oil clutch water pump, the driving plate is located to the left of the driven plate, and a sealing ring is provided between the front cover and the pulley. In practical applications, the sealing performance between the front cover and the pulley can be improved by providing a sealing ring.

[0009] In the aforementioned electronically controlled silicone oil clutch water pump, a water chamber plug is installed inside the pump body, and a water seal is installed between the water chamber plug and the shaft bearing. In practical applications, by installing the water chamber plug inside the pump body and installing a water seal between it and the shaft bearing, the internal water chamber of the pump can be sealed to prevent coolant leakage. Simultaneously, it ensures a dry and clean operating environment for the shaft bearing. The water seal, installed between the water chamber plug and the shaft bearing, enhances the sealing performance of the water chamber, preventing coolant from entering the shaft bearing and avoiding damage due to water ingress, thus extending the bearing's service life.

[0010] In the aforementioned electronically controlled silicone oil clutch water pump, a clutch cover is bolted to the left side of the front cover, and the detection end of the speed sensor is located on the top of the speed plate. In practical applications, by setting up a clutch cover, the internal components of the clutch are further sealed, enhancing the overall structural protection and reducing the impact of external factors on components such as the driving plate and driven plate.

[0011] In the aforementioned electrically controlled silicone oil clutch water pump, a working chamber is formed between the driving plate and the driven plate, and the interior of the working chamber is filled with silicone oil. In practical applications, by using silicone oil, which fills the working chamber formed between the driving and driven plates, the silicone oil utilizes its own viscous properties to transmit power from the driving plate to the driven plate, thereby driving the shaft bearing and impeller to rotate. The distribution and flow state of the silicone oil can be controlled by a valve assembly. When the water pump needs to adapt to different operating conditions, the valve assembly adjusts the amount or distribution of silicone oil in the working chamber, changing the viscous connection strength of the silicone oil to the driving and driven plates. The stronger the viscosity, the higher the power transmission efficiency and the higher the speed of the driven plate and subsequent components; the weaker the viscosity, the lower the speed. Ultimately, the water pump speed is intelligently adjusted according to the operating conditions, achieving the goals of adapting the coolant flow rate, avoiding excessive cooling during cold starts, and reducing power loss and oil consumption.

[0012] In the aforementioned electronically controlled silicone oil clutch water pump, a sealing strip is adhered to the right side of the protective cover, and a drying box is fixedly connected to the left side of the protective cover. A cover is fitted onto the left side of the drying box, and a drying hole is provided on the right side of the drying box. A conduit is connected to the front and rear sides of the left side of the drying box. In practical applications, the sealing strip enhances the sealing fit between the protective cover and the pump body, improving the protective effect and preventing dust and moisture from entering the sensor installation area through gaps. The drying box allows for the placement of a desiccant, which absorbs moisture from inside the protective cover through the drying hole, maintaining a dry internal environment and protecting precision components.

[0013] Compared with existing technologies, the advantages of this electronically controlled silicone oil clutch water pump are: it can save energy, accurately control the water pump speed, and achieve intelligent adaptation of coolant flow to working conditions, which can avoid excessive cooling during cold starts and efficiently cope with high load heat dissipation, thereby significantly reducing power loss and fuel consumption.

[0016] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments. Example 1

[0017] like Figure 1 and Figure 2As shown, an electronically controlled silicone oil clutch water pump includes a pump body 1. A pulley 2 is movably connected to the left side of the pump body 1 via a sealed bearing. A front cover 3 is bolted to the left side of the pulley 2. A shaft bearing 4 is installed through the right side of the pump body 1. An impeller 5 is bolted to the right end of the shaft bearing 4. A connecting plate 6 is installed in the inner cavity of the front cover 3. A drive plate 7 is bolted to the right side of the connecting plate 6. A driven plate 8 is fixedly connected to the left side of the shaft bearing 4. A valve plate assembly 9 is installed between the drive plate 7 and the driven plate 8. A speed plate 10 is fixedly sleeved on the right side of the shaft bearing 4. A voltage sensor 11 and a speed sensor 12 are respectively installed on the top left side of the pump body 1. A protective cover 13 is bolted to the top left side of the pump body 1. A solenoid valve 14 is installed inside the pump body 1.

[0018] In actual manufacturing, the driving plate 7 is located to the left of the driven plate 8, and a sealing ring 15 is provided between the front cover 3 and the pulley 2.

[0019] In actual manufacturing, a water chamber plug 16 is provided inside the water pump body 1, and a water seal 17 is provided between the water chamber plug 16 and the shaft bearing 4.

[0020] In actual manufacturing, the left side of the front cover 3 is connected to the clutch cover 18 by bolts, and the detection end of the speed sensor 12 is located on the top of the speed plate 10.

[0021] In actual manufacturing, a working cavity is formed between the active plate 7 and the driven plate 8, and the interior of the working cavity is filled with silicone oil.

[0022] In actual manufacturing, when the engine is running, the belt drives the pulley 2 on the left side of the water pump body 1 to rotate. The pulley 2 drives the front cover 3 and the connecting plate 6 inside the front cover 3 to rotate synchronously, which in turn drives the drive plate 7 bolted to the right side of the connecting plate 6 to rotate. The working cavity formed by the drive plate 7 and the driven plate 8 fixed on the left side of the shaft bearing 4 is filled with silicone oil. The drive plate 7 transmits power to the driven plate 8 with the help of the silicone oil's viscosity. The driven plate 8 drives the shaft bearing 4 and the impeller 5 connected to the right end of the shaft bearing 4 to rotate, realizing coolant circulation. During speed control, the voltage sensor 11 and speed sensor 12 on the top left side of the water pump body 1 will... Real-time operating data is collected and fed back to the solenoid valve 14 inside the water pump body 1. The solenoid valve 14 then controls the valve plate assembly 9 to adjust the amount or distribution of silicone oil in the working chamber. During cold start, the valve plate assembly 9 reduces the amount of silicone oil involved, reduces the viscous bonding strength of the silicone oil, causes the driven plate 8 to rotate slower, reduces coolant circulation to avoid overcooling, and shortens the engine warm-up time. Under high load, the valve plate assembly 9 increases the amount of silicone oil involved, enhances the viscous bonding strength, increases the rotational speed of the driven plate 8, increases the coolant flow for efficient heat dissipation, and prevents the engine from overheating. Under normal operating conditions, the silicone oil state is dynamically adjusted to maintain stable speed and balance heat dissipation and energy consumption. Example 2

[0023] like Figure 3 and Figure 4 As shown, in actual manufacturing, a sealing strip 19 is glued to the right side of the protective cover 13, and a drying box 20 is fixedly connected to the left side of the protective cover 13. A box cover 21 is fitted on the left side of the drying box 20, and a drying hole 22 is opened on the right side of the drying box 20. A conduit 23 is connected to the front and rear sides of the left side of the drying box 20.

[0024] In actual manufacturing, the box cover 21 is opened, and bagged silica gel desiccant is added to the inside of the drying box 20. Then, the protective cover 13 is installed on the left side of the water pump body 1 by bolts. At this time, the voltage sensor 11 and the speed sensor 12 are both located inside the protective cover 13. The silica gel desiccant inside the drying box 20 absorbs the moisture inside the protective cover 13 through the drying hole 22, maintaining a dry internal environment, thereby protecting the voltage sensor 11 and the speed sensor 12 from dust and moisture.
