Description

Technical Field

[0001] This utility model relates to the field of silicone oil clutch technology, specifically a low-torque counterclockwise rotating silicone oil clutch. Background Technology

[0002] As a core component of the engine thermal management system, the silicone oil clutch transmits torque through the shear force of silicone oil to achieve speed regulation and is widely used in fields such as cooling fan control. However, traditional silicone oil clutches have limitations in the design of the oil return path, resulting in nonlinear and fluctuating speed regulation, especially under low torque and counterclockwise rotation conditions.

[0003] In existing technologies, the return oil mechanism of silicone oil clutches mostly relies on centrifugal force and a one-way valve structure to return silicone oil from the working area to the reservoir. For example, the silicone oil in the silicone oil clutch exits from the reservoir through the oil outlet and enters the working area. During return, it directly returns to the reservoir through the return groove. Since the return groove is located downstream of the drive disc's rotation direction, the silicone oil exiting the return groove is close to the return hole (return port), resulting in a shorter return time. This structure is not conducive to linear speed regulation.

[0004] Therefore, how to improve the oil return structure of the silicone oil clutch, extend the oil return path and time, and improve the smoothness and linearity of speed regulation has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0005] In view of the shortcomings in the prior art, this utility model provides a low-torque counterclockwise rotating silicone oil clutch.

[0006] The technical solution adopted by this utility model is: a low-torque counterclockwise rotating silicone oil clutch, including an upper cover, a lower cover, and a drive disc installed between the upper cover and the lower cover. Drive gear rings are provided on the upper and lower end faces of the outer ring of the drive disc, and an oil storage chamber is provided on the inner ring of the drive disc. An oil return gap is formed between the outer edge of the drive disc and the upper and lower covers. Driven gear rings are provided on the upper and lower covers. The gap formed by the interlocking and meshing of the driven gear rings and the drive gear rings constitutes a working area. The drive disc is provided with a connection for communicating with the oil storage chamber. The oil return hole and oil outlet hole are provided. An oil baffle block is provided on one side of the oil return port of the oil return hole. An oil outlet channel is provided on the front and back of the drive disc. The oil outlet channel includes a connecting channel that connects multiple drive gear rings, an annular channel located on the outer ring, and an oil return groove that connects to the oil return gap. The annular channel extends to the upstream side of the oil return port of the oil return hole in the rotation direction, and the oil return groove is located on the upstream side of the oil return port of the oil return hole in the rotation direction. The oil baffle block is located on the upstream side of the oil return port of the oil return hole in the rotation direction.

[0007] One end of the oil outlet is connected to the connecting channel, and the oil outlet channel on the front and the oil outlet channel on the back of the active disc are connected through a through slot.

[0008] Furthermore, the active disk is used to rotate counterclockwise.

[0009] Furthermore, the arc between the oil return groove and the oil return port is less than 30 degrees.

[0010] Furthermore, the return oil groove has an inclined surface that slopes upstream in the direction of rotation of the drive disc.

[0011] Furthermore, several oil storage ports are provided at intervals on the active gear rings on both sides of the outer ring of the active disk.

[0012] Furthermore, there are three oil storage ports, which are distributed in a circular array on the active gear ring with the center of the active disk as the center.

[0013] Furthermore, the oil storage port has a polygonal, circular, or elliptical structure.

[0014] The beneficial effects of this utility model are: by using an annular channel and placing the oil return groove connected to it upstream of the oil return port in the rotation direction of the oil return hole, and simultaneously, the oil baffle is also located upstream of the oil return port in the rotation direction of the oil return hole, the oil return path is effectively extended (see details). Figure 6 and Figure 7 (Comparison of medium-path return oil return). This significantly increases the time for silicone oil to return from the working area to the reservoir, effectively promoting the smoothness and stability of speed regulation. This design mitigates sudden changes in silicone oil flow rate, avoids the problem of sudden reduction in silicone oil volume caused by traditional short-path return oil, and makes torque transmission smoother, thus making it easier to achieve linear speed regulation.

[0015] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The utility model will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

The drive disc is provided with an oil return hole 11 and an oil outlet hole for communicating with the oil storage chamber. 12. An oil baffle 10 is provided on one side of the oil return port 9 of the oil return hole 11. An oil outlet channel is provided on the front and back of the active disc 3. The oil outlet channel includes a connecting channel 13 that connects multiple active gear rings, an annular channel 14 located on the outer ring, and an oil return groove 15 connected to the oil return gap. The annular channel extends to the upstream side of the oil return port of the oil return hole in the rotation direction, and the oil return groove is located on the upstream side of the oil return port of the oil return hole in the rotation direction.
