AI Technical Summary
Existing silicone oil clutches are prone to silicone oil entering the engagement chamber after shutdown, causing the clutch to engage during cold starts, increasing the engine's warm-up rate and fuel consumption.
A silicone oil clutch is designed, which divides the oil storage chamber into a front oil chamber and a rear oil chamber by setting a partition plate in the oil storage chamber, and sets an oil outlet and a return oil channel between the front oil chamber and the engagement chamber. The opening and closing of the oil outlet is controlled by a solenoid valve plate. When the clutch is engaged, the silicone oil enters the engagement chamber and returns to the front oil chamber through the return oil channel. When the clutch is stopped, the silicone oil flows into the rear oil chamber for storage.
It improves the circulation efficiency of silicone oil, reduces the amount of silicone oil in the oil reservoir, enhances the reliability of clutch engagement, improves cold start performance, and prevents the engine from heating up too quickly and increasing fuel consumption.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of clutch technology, and more specifically, to a silicone oil clutch. Background Technology
[0002] Automotive silicone oil clutches use silicone oil as the medium, leveraging its high viscosity to transmit torque. A temperature sensor automatically controls the engagement and disengagement of the fan clutch based on the air temperature behind the radiator. When the engine temperature is low, the silicone oil remains in the reservoir, the fan clutch is disengaged, and the fan speed is slow, essentially idling. When the engine temperature is high, the silicone oil flows into the engagement chamber of the clutch, engaging the fan clutch and regulating engine temperature. However, current silicone oil clutches tend to allow silicone oil to enter the engagement chamber after shutdown. Upon restarting, the clutch is engaged, accelerating engine warm-up and increasing fuel consumption. Utility Model Content
[0003] To overcome the shortcomings of the prior art, this utility model provides a silicone oil clutch.
[0004] This utility model provides a silicone oil clutch, including a main shaft, a housing, and a drive plate. The drive plate is fixed to the front end of the main shaft, and the housing is rotatably connected to the main shaft. A front cover is connected to the front side of the housing, and the housing and the front cover form a meshing cavity. The meshing cavity is for the meshing part of the drive plate to be inserted. An oil storage cavity is provided between the drive plate and the front cover. A partition plate is provided in the oil storage cavity, which divides the oil storage cavity axially into a front oil cavity and a rear oil cavity. An oil outlet hole and a solenoid valve plate for controlling the opening and closing of the oil outlet hole are provided in the front oil cavity. The oil outlet hole communicates with the meshing cavity to allow silicone oil from the front oil cavity to flow into the meshing cavity. The partition plate is provided with at least one through hole connecting the front oil cavity and the rear oil cavity. The through hole and the oil outlet hole are located on opposite radial sides of the center of the oil storage cavity. A return oil channel is provided on the front cover to return the silicone oil in the meshing cavity to the front oil cavity.
[0005] Compared with the prior art, the silicone oil clutch disclosed in this application has the following advantages: When the clutch is engaged, the silicone oil in the front oil chamber enters the engagement chamber through the oil outlet, and the silicone oil in the engagement chamber flows back into the front oil chamber through the return oil channel, reducing the circulation path of the silicone oil, making the circulation efficiency of the silicone oil high, reducing the amount of silicone oil in the reservoir, and improving the reliability of the clutch engagement; when the solenoid valve plate closes the oil outlet, the silicone oil in the front oil chamber can flow into the rear oil chamber through the through hole, reducing the amount of silicone oil remaining in the front oil chamber. After the clutch stops, most of the silicone oil is stored in the rear oil chamber, reducing the amount of silicone oil flowing into the engagement chamber, avoiding clutch engagement during cold starts, improving cold start performance, and preventing the engine from heating up too quickly and increasing fuel consumption.
[0006] In one possible implementation, the active plate is provided with an oil storage cover on the side facing the return oil channel, and the oil storage cover and the active plate form the oil storage cavity. The oil storage cover is provided with an oil return hole for connecting to the return oil channel, and the oil return hole is located on the front oil cavity.
[0007] Compared with existing technologies, the above technical solution can achieve oil storage in the oil storage chamber.
[0008] In one possible implementation, both the oil reservoir cap and the partition plate are snapped onto the drive plate, with the partition plate located between the oil reservoir cap and the drive plate.
[0009] Compared with existing technologies, the above technical solution facilitates the installation of the oil reservoir cap and partition plate, and is conducive to the formation of the front oil chamber and the rear oil chamber.
[0010] In one possible implementation, the oil outlet is located on the active plate, and the active plate is provided with ribs on both sides around the oil outlet. The ribs and the active plate cooperate to form an oil storage groove, and the opening of the oil storage groove is connected to the partition plate to jointly form the rear oil chamber.
[0011] Compared with existing technologies, the above technical solution can achieve a semi-closed structure of the rear oil chamber, allowing silicone oil to enter and exit only through the through hole, which is beneficial for storing silicone oil in the rear oil chamber.
[0012] In one possible implementation, the partition plate has an oil storage tank protruding from the front oil chamber, and the oil storage tank is connected to the rear oil chamber.
[0013] Compared with existing technologies, the above technical solution can reduce the volume of the front oil chamber and increase the volume of the rear oil chamber. After the oil outlet is closed, more silicone oil enters the rear oil chamber and is stored, reducing the amount of silicone oil entering the meshing chamber and improving the performance of cold start after shutdown.
[0014] In one possible implementation, the partition plate is provided with five through holes spaced circumferentially.
[0015] Compared with existing technologies, the above technical solution facilitates the entry and exit of silicone oil into and out of the oil cavity, and makes silicone oil storage easier. Attached Figure Description

[0027] See Figures 1 to 5This application discloses a silicone oil clutch, including a main shaft 1, a housing 2, and a drive plate 3. The drive plate 3 is fixed to the front end of the main shaft 1. The housing 2 is rotatably connected to the main shaft 1. A front cover 4 is connected to the front side of the housing 2. The housing 2 and the front cover 4 form a meshing cavity 5, into which the meshing part of the drive plate 3 is inserted. An oil storage cavity 6 is provided between the drive plate 3 and the front cover 4. A partition plate 7 is provided in the oil storage cavity 6, dividing the oil storage cavity 6 axially into a front oil cavity 61 and a rear oil cavity. 62. The front oil chamber 61 is provided with an oil outlet 8 and a solenoid valve plate 9 for controlling the opening and closing of the oil outlet 8. The oil outlet 8 is connected to the engagement chamber 5 for allowing the silicone oil in the front oil chamber 61 to flow into the engagement chamber 5. The partition plate 7 is provided with at least one through hole 71 connecting the front oil chamber 61 and the rear oil chamber 62. The through hole 71 and the oil outlet 8 are located on opposite radial sides of the center of the oil storage chamber 6. The front cover 4 is provided with a return oil channel 41 for returning the silicone oil in the engagement chamber 5 to the front oil chamber 61.
[0028] As described above, when the clutch is engaged, the silicone oil in the front oil chamber 61 enters the engagement chamber 5 through the oil outlet 8. The silicone oil in the engagement chamber 5 then flows back into the front oil chamber 61 through the return oil channel 41, reducing the circulation path of the silicone oil, thus increasing its circulation efficiency, reducing the amount of silicone oil in the reservoir 6, and improving the reliability of the clutch engagement. When the solenoid valve plate 9 closes the oil outlet 8, the silicone oil in the front oil chamber 61 can flow into the rear oil chamber 62 through the through hole 71, reducing the amount of silicone oil remaining in the front oil chamber 61. After the clutch stops, most of the silicone oil is stored in the rear oil chamber 62, reducing the amount of silicone oil flowing into the engagement chamber 5, avoiding clutch engagement during cold starts, improving cold start performance, and preventing the engine from overheating and increasing fuel consumption.
[0029] In this embodiment, the active plate 3 is provided with an oil storage cover 10 on the side facing the oil return channel 41. The oil storage cover 10 and the active plate 3 form the oil storage cavity 6. The oil storage cover 10 is provided with an oil return hole 101 for connecting to the oil return channel 41. The oil return hole 101 is located on the front oil cavity 61, thereby enabling oil storage in the oil storage cavity 6. The oil storage cover 10 has a ring structure.
[0030] In this embodiment, the oil reservoir cap 10 and the partition plate 7 are both snapped onto the active plate 3. The partition plate 7 is located between the oil reservoir cap 10 and the active plate 3, which facilitates the installation of the oil reservoir cap 10 and the partition plate 7 and is conducive to the formation of the front oil chamber 61 and the rear oil chamber 62.
[0031] In this embodiment, the oil outlet 8 is located on the active plate 3. Ribs 31 are provided on both sides of the active plate 3 around the oil outlet 8. The ribs 31 and the active plate 3 cooperate to form an oil storage groove 32. The opening of the oil storage groove 32 is connected to the partition plate 7, together forming the rear oil chamber 62. This achieves a semi-closed structure for the rear oil chamber 62, allowing silicone oil to enter and exit only through the through hole 71, which is beneficial for storing silicone oil in the rear oil chamber 62. Specifically, the ribs 31 are integrally formed with the active plate 3.
[0032] In this embodiment, the partition plate 7 has an oil storage tank 72 protruding from the front oil chamber 61. The oil storage tank 72 is connected to the rear oil chamber 62, thereby reducing the volume of the front oil chamber 61 and increasing the volume of the rear oil chamber 62. After the oil outlet 8 is closed, more silicone oil enters the rear oil chamber 62 and is stored, reducing the amount of silicone oil entering the meshing chamber 5 and improving the performance of cold start after shutdown.
[0033] In this embodiment, the partition plate 7 is provided with five through holes 71 spaced apart along the circumference, which facilitates the entry and exit of silicone oil into the oil cavity 62 and makes silicone oil storage convenient.
